2018 Chevrolet Silverado 1500 Transmission Problems

2018 6.2l engine dropped 3 lifters at just a little over 70k miles. Vehicle is my wife’s and almost caused her and my child to have an accident while traveling on highway at posted speed. Vehicle lost power that resulted from premature engine failure resulting in vehicle losing power to the brakes and steering while in heavy traffic.

The transmission has been shifting hard. I have had it serviced to try and address the issue. It continued to shift hard, until suddenly slamming me down and locking me into first gear.

I purchased my truck in December 2018 which is a 2018 Chevrolet Silverado 1500 4x4 crew cab automatic from Servco Chevrolet Dealership in Waipahu, Hawaii and making monthly payments for my truck February of 2019 truck runs good and purchased the warranty also had my oil and service changed when time is due which I always kept up.

on or about [XXX] while driving through Olathe Kansas, the torque converter and subsequently the transmission on my 2018 Chevy Silverado 1500 failed while driving in heavy traffic. While navigating to a safe place outside the high-speed traffic corridor, the truck would run at approximately 3000 RPM at a speed of 40MPH. By sheer luck, we were not involved in a traffic accident.

We just purchased the truck from a Chevrolet dealership 6 days prior took it on a trip to Missouri. Truck transmission shuddered then downshifted nearly causing a rear end accident behind us. Luckily the driver was attentive and did not hit us

My truck has had transmission issues since we purchased it. At 79,000 miles the factory transmission finally went out and needed replaced. The truck currently has 81,000 miles on it and is already having transmission problems with the rebuilt parts.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact stated that the vehicle was shaking and jerking.

The transmission has been slipping since the truck was brand new (<100 miles) and has always slipped but recently became worse and slips all of the time. This is a known issue with this transmission and should be included in the recall. The transmission slipped going around a curve and almost lost control of the vehicle.

Doing 65mph on interstate on cruise control, the transmission went into 'false neutral' and engine revs went sky high. Truck slowed quickly, almost got rear ended. After that, the transmission did engage and I barely made it home.

2 separate lifter failure incidents at 61,000 miles. One failure, happened on a busy interstate, while flowing with the speed of traffic. Truck started to misfire, jerk and blow smoke.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that the vehicle had experienced several safety related failures which included unintended acceleration. The contact indicated that the transmission needed to be replaced on multiple occasions due to the failure.

On or about Feb 9, Power Train transmission, Modular’s. While traveling about 40mph the truck shifted suddenly to low gear, and the water pump blew resulting in steam or smoke from engine hood. Automatic shifting was not possible, after slowing to 5-10 MPH check if mauls shifting was an option.

My 10 speed transmission is failing, problem is a shutter in the transmission at various speeds. Have the shutter verified as not wheel balance problem, as all wheels were spin balanced. Upon looking up info online they said it could be dangerious and cause an accident....

Motor vehicle accident 4/21/22. Vehicle stalled hit by 18 wheeler. Several times on several occasions after that on several days vehicle stalled in interstates with multiple 18 wheelers, trucks cars almost hitting me/my vehicle each time it stalled. Now and since May 2022, the transmission completely failed and is inoperable at this time. The stalling in the middle of interstate traffic where the speed limit on 4/21/22 is 55mph & on the interstate 65mph(The vehicle coasted slowly to the side of the road & stopped changing gears to go in either direction)

April 2022 & 5 2022 Complete transmission failure in traffic ALMOST causing death in traffic, emissions failure, leather seat defect REPEATED left fog light failure

When entering traffic, upon acceleration the truck stalls, and shutters. Going into traffic a vehicle had to maneuver to avoid collision with me. I took it to the dealer and they said transmission should get a flush and transmission oil was low.

Several times, while driving right around 55 MPH, the transmission downshifted for no reason on thruway conditions. When this happened, it was almost like slamming on the brakes quickly. On all occasions, my body lurched forward.

In may 2018 I purchased a new chevy silverado lt z71 pu. I live in colorado and when I drive the truck down the I-70 mountain pass the transmission is downshifted beyond what io would call a safe down shift. Im traveling down the pass, just coasting, down hill assist mode is off @ roughly 55 MPH the transmission down shift hard.

Your engine is making a ticking noise and the check engine light is on due to a bent push rod caused by a failed lifter in the AFM (Active Fuel Management) system — a manufacturing defect. Your mechanic identified this as a known issue affecting 2018-2021 Silverados, but GM has refused warranty coverage and Goodwill assistance despite acknowledging the problem stems from their manufacturing error. Fixing this will require removing the engine valve cover and replacing the bent push rod and failed lifter assembly.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle hesitated or shuddered while depressing the accelerator pedal. There was no warning light illuminated.

Torque converter failed which LED to premature transmission failure at 115,000. Known common issue with 6L80 and TSB advising this.

2018 Chevy Silverado with 84,000 miles and the transmission is broken. Truck is currently in a shop to have a new transmission installed.

The components that failed were the transmission because the vehicle was driving and continued to slow down until it came to a complete stop gradually, and had to be pushed home. And also, there was an issue with the doors unlocking on their own and all windows rolling down by themselves. The safety risk was the issues that happened without any knowledge of any issues at all with the vehicle.

Bad torque converter cause transmission to totally fail. Had chevy do transmission flush,2 yrs ago. Back in Aug 2024, transmission started to slip,while driving,then totally failed,no forward or reverse gears,nothing, had truck towed into chevy dealer, almost $7000.00 later,transmission had to be replaced.

My transmission had a history of failing trans symptoms, all documented at the dealer from 10,000 miles until it ultimately failed at 127,000 miles. Those symptoms where a down-shift thud, confusion to what gear it should be in, shuddering, shaking and fluid temp running hot without towing a load. Was told by the dealer this was all normal, that the transmission was "still learning".

Transmission slipping and shuddering when fluid warms up. Dealership diagnosed torque converter/transmission failure. Stated it may cause transmission lockup while driving

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the vehicle stalled and lost motive power. The vehicle was taken to the dealer where it was diagnosed with engine failure.

Transmission Failure & Torque Converter Clutch Failure, Less than 90,000 miles on vehicle. This is a known issue with this year and model truck that GM is aware of. It has been inspected by the certified dealer and they are aware that this is a known issue.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving 35 MPH, the transmission failed to operate as designed and the vehicle started losing motive power. The contact stated that the vehicle returned to normal functionality afterwards.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while her husband was driving at an undisclosed speed, the vehicle was shaking erratically. The vehicle was taken to an independent mechanic where it was diagnosed with transmission failure.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed and while attempting to accelerate, the vehicle hesitated. The contact took the vehicle to an independent mechanic where the vehicle was diagnosed with transmission failure.

2018 Chevrolet Silverado 2020 was under warranty (22,000 miles)….felt a little vibration in my steering wheel and suspected a transmission problem and called the dealer’s service department. I told them what I felt and they said…yes you have a transmission problem (that Chevrolet knows about) bring it in and we will fix it. The fix was…change transmission fluid to synthetic.

Vehicle wouldn't accelerate while in moving traffic. RPM gauge would move but speed gauge would not and vehicle would not accelerate past 30-35. When I pulled over and put my vehicle in park then attempted to put in drive, it would not move.

The GM 6L80 transmissions have a faulty torque converter. When it goes out it causes a horrible vibration and drive train failure. Which leaves you stranded in traffic or on the side of a busy highway.

Torque converter was broken and destroyed my transmission just at 90,000 miles. I could easily have been stranded in major city traffic at any point if this had failed any earlier. This problem has been known in various GMC vehicles throughout the years.

On Saturday Aug 6th, 2022 my girlfriend and I were driving in my 2018 Chevy Silverado and the car just came to a complete stop really hard. Once the truck froze up, the car would go FOWARD but very slow, jerkish, and sluggish. We were almost hit by three cars behind us when the truck froze up.

The transmission failed at 81k miles. Upon doing some research, it sounds like this is caused by the wrong transmission fluid that was installed by GM, not myself, the owner. If known about early enough, flushing the transmission 3 times and replacing with the newest transmission fluid is to correct the problem.

For months this truck as stuttered while driving. Eventually one day the RPMs would shoot to 3500 when trying to shift gears and would struggle to shift. After having the spark plugs replaced and a tune up ($660 later) it started randomly just losing power to the engine while driving.

I was on highway 65 coming out of Rocklin Ca going back to Yuba City Ca. The Chvey Silverado with out any warning it just lost power and I had to pull over. I am glad I was on the slow lane.

When coming to a full stop, the transmission down shift really hard. It makes the vehicle jerk forward. It doesn't matter if you are going up hill/downhill or on a flat road.

Tl* the contact owns a 2018 chevrolet silverado 1500. While driving 55-60 MPH, the vehicle failed to accelerate, lost power, and spontaneously moved. There were no warning indicators illuminated; however, the "icy road conditions drive with care" message was displayed.

Tl* the contact owns a 2018 chevrolet silverado 1500. The contact stated that the vehicle was experiencing transmission failure. After the contact went back and forth with the manufacturer and dealer (bill cramer chevrolet buick gmc, 2251 w 23rd st, panama city, fl 32405, (850) 250-1403), they settled on trading the contact's 2015 silverado for a 2018 silverado with the same transmission failure.

The transmission slips or shudder, also has free wheeled when going down hill at slow speeds, also occurs in reverse, usually about 1 to 2 car lengths. Have returned to the dealer several times and been told that gm does not have a remedy. Had the service recommendation of a transmission flued flush done twice with different fluid installed with no change.

Parked and shut off, disconnected trailer. Truck rolled back while in park. I jumped out of way and tried to open door to stop.

Transmission skips 1st gear and jumps and shakes vibrates. The transmission has to have a total rebuild

-Transmission failed. - Driving down the highway and the truck just quit. (Morning rush hour traffic) -truck was towed to my mechanic -only made a weird noise the day before.

My transmission failed at around 69,000 miles. This was confirmed by the dealership. I bought my vehicle from and was covered under warranty.

While pulling a 14' enclosed trailer when I left off the gas pedal there was a sudden low growl/vibration coming from the bed area of the truck. I was slowing down for a red light and it started at around 20mph.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle shuddered abnormally. No warning light was illuminated.

My truck has been into the dealership repeatedly from Aug 2024 to where it sits now to this day because of the engine and the electronic fuel management system. This fuel management system has destroyed my engine by allowing excessive oil consumption to which it turns the oil black. The engine goes from v8 to 4 cylinder to save on fuel which makes the engine work harder.

shudder while driving

My 2018 Silverado z71crew cab LT , 5.3L engine was having issues with hold Freon in AC unit. We took to dealer to be fixed in June 2025. They added Freon and it was running good for a week then once again blew but no cold air.

No check engine light come on until continued driving over 15-20 miles. Transmission slams into second gear when taking off or when stopping it may or may not downshift into first causing safety issues when in traffic. Possible electrical error or clutch inside transmission.

10 miles from home on [XXX] after Thanksgiving with my children sleeping at [XXX] in snowy cold weather, my engine began to fail. Power was limited on hills and the check engine light would come on and go back off when on flat or downhill. The next morning I took my truck to the dealer that I purchased it from where I was told the lifters had failed and I need a new engine.

The contact's husband owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle hesitated while depressing the accelerator pedal. The vehicle was taken to an independent mechanic where the contact was informed that metal shaving were discovered in the radiator due to a defective torque converter.

I’ve had to have the transmission replaced before hitting 123k miles There is a constant shake, tremble in the car that dealer mechanics cannot figure out and they relate the issue to the transmission Electrical dashboard and AC lightning fixture burnt out

Vehicle went into limp mode on I 65 in Indiana. Chevy dealer replaced tvb/ thermal bypass valve with newer version that opens at a lower temperature.Hard to get vehicle to the side of the highway. State Police arranged a tow truck to remove vehicle from highway.

Driving on the fwy going 73mph While running Transmission stopped working and I’m not able to accelerate to move forward and safely pull over to the shoulder. The problem was not been confirmed by the dealer or service center. The vehicle was not been inspected by anyone.

The automatic transmission in my 2018 Chevrolet Silverado 1500 with the 4.3L V6 has experienced repeated failures and overheating events starting shortly after a scheduled dealer transmission flush at approximately 50,000 miles.

TRANSMISSION STARTED SHIFTING WEARD CONTACTED DEALERSHIP. THEY STATE THIS UNIT IS NOT UNDER RECALL BUT IT IS AN 6L80 AND IT IS ALL OVER YOU TUBE AND THE INTERNET ABOUT FAILURES THAT START WITH THE PM VALVE AND/OR THE TORQUE CONVERTER HOUSING THAT IS STAMPED BUT MOUNTING BRACKETS ARE WELDED TO IT CAUSING HARDED STEEL TO MEET STAMPED STEEL CAUSING FRICTION AND WEAR THAT POLUTES THE REMAINDER OF THE TRANSMISSION AND CAUSES FAILURE BEFORE 100000 MILES; USUALLY JUST AFTER 50000ISH. WHEN TRANSMISSION FAILS IT CAN CAUSE LOSS OF PROPULSION OR COLLION.

Brakes sometimes require more pressure to stop or slow down. Transmission shutters and makes a clunking noise between shifting points. Kind of a sound bad u-joints make.

My vehicle has had transmission and engine problems that should not have been an issue until after at least 100,000 miles. At 11,577 miles I reported hard down shifting as well as a hard shift / kick when going from reverse to drive when the transmission would feel like it would slip and then kick when shifting from 1st to 2nd gear on automatic transmission. There were no codes and dealership said they couldn't duplicate problem. At 58517 miles the service 4x4 warning light came on as well as a shifting problem was continuing. A transmission valve body was replaced and a transmission service / fluid replacement was done under warranty or extended warranty. The shifting problem has continued. It has come to my understanding that Chevrolet put out a bulletin about changing the transmission fluid should solve the problem and to tell customers that some hard shift could be normal and not a problem. And I have heard about some class action lawsuits that have been filed. A second and more major issue was the 5.3 liter engine failure that occured at 62,093 miles after having a tapping noise develop and some loss of power. But this issue began earlier at 40,125 miles when I had a fuel injection clean due to it running rough. Extended warranty replaced engine with a used motor and I was still charged $1158.93 for amounts extended warranty didn't cover. My Son's 2015 Silverado 1500 which I owned previously had to have the transmission rebuilt for just under $5,000 just out of extended or manufacturer's warranty. We don't pay $60,000-$70,000 to have engines and transmission fail before 100,000 miles and before the loans on vehicles are paid off. We shouldn't have to be paying a loan on a vehicle we can't even drive because it is in the shop for an extended period of time. At 62,298 miles after getting the truck back from the engine failure, the starter then failed and was replaced under extended warranty with $133.76 cost going to me.

The truck started shuttering one day it was like I was driving on the drunk bumps but I wasn't. Also it will drop gears when it shouldn't and at times it will kinda jump like it's losing power and don't want to go. I have taken it to my step dad who has been a transmission mechanic all his life and he said the transmission needs to be rebuilt but even rebuilding it won't solve the problem because it is a flaw in the way it was made so rebuilding it they use the same parts and everything so it will eventually do the same thing again it's all just a matter of when. He also had me go to another really good transmission guy and he said that we could replace the torch converter but still may need a rebuild l. I don't know if any that has to do with my passenger tire wear or my wheel bearing coming loose while driving only one bolt was holding it on when my husband checked it. The wheel bearing coming loose is pretty big safety problem. As for the transmission my step dad works at a transmission shop and he said they get probably 3 to 5 trucks a week having the same problem mine is having and I know they have been recalls on other trucks that have the same problem as mine just my one wasn't in the batch they recalled .

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, there was an abnormal shuddering sound coming from the engine compartment. The contact stated that the stabili-trak warning light was illuminated. Additionally, on one occasion when the vehicle was started and shifted into drive(D), the vehicle failed to accelerate. The vehicle was taken to a dealer but was not yet diagnosed. The manufacturer was not notified of the failure. The failure mileage was 106,000.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that the vehicle was vibrating abnormally while driving 45 MPH. There were no warning lights illuminated. The vehicle was taken to an independent mechanic who determined that the brake pads and rotors needed to be replaced. The mechanic later determined that the torque converter needed to be replaced. The local dealer was contacted, and determined there were no recalls on the VIN related to the failure. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that there was no recall coverage for the failure. The failure mileage was approximately 75,000.

Sometimes when traveling higher speeds (55-70)and braking going downhill, a hard brake will come out of nowhere. Not enough lock up the brakes or anything but enough to scare the crap out of you!!! If it would happen to a elderly person or a less experienced driver, they could probably lose control or wrack. With the power train...sometimes when accelerating(from a stop or low speed)it seems as though it gets stuck in gear or skips a gear. You won't have any power then bam... almost cerps the back tires

Hard shift when transmission is shifting around 70 MPH and also transmission temperature keeps rising above 230 degrees. Shuddering when shifting after city driving.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the vehicle intermittently shuddered. No warning lights was illuminated.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving 30 MPH, the transmission became stuck in second gear. The contact pulled over the right side of the road and turned off the vehicle for two minutes.

transmission temprature excessively high, there is a TSB#21-NA-199 Document[XXX] on Thermo bypass vlave on 2018 trucks 6 speed transmissions. 200 degree transmission temp is too high. Service advisor originally said thats normal, after high temp issue a 5th time.

Had to replace rear end now transmission is starting to act up like might be going out (the truck started by like having a shake as you drive ot not for long period just every so often to when I gave ot rhe gas the really loud whinning noise let off gas it stopped )looked up to see if any others and many others with the same model as mine is having same trouble as I am and have not seen any recalls,but many people have been having same issues .

Transmission failed and truck shut down mid road while going uphill. Shifting jumps when gears are switched and power jumps and goes down while stepping on gas pedal. At first it showed a check engine light but because I was traveling I had to skip and tried turning on again.

Transmission jerks with hard shift and rough idle

Purchased this vehicle from a used car dealership 2 months ago. Now the transmission seems to be going out with 132,000 miles on it and funny noise from the transfer case. I have researched and found numerous complaints about the drive train on this vehicle and as a disabled veteran I don't have the funds to have it fixed.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the contact stated that the vehicle felt like the transmission was slipping. The contact stated that the transmission was shifting abnormally.

Transmission vibrates when it approaches 35 MPH and 65 MPH. The vibration feels like rumble strips and last for 3 seconds

Transmission jerking on downshift between 3/2 and 2/1 gears! I have seen GM has been aware of a recent transmissions issue with 2012-2018 plus 2019-2022 years

I've been in and out of dealers over the transmission shifting points and hard down shifts when almost stopped. And the a/c condenser has cracked on the side for no known reason at 75k miles except for the fact of bad manufacturing

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at unknown speeds for an extended period, the transmission temperature, traction control, and the check engine warning lights illuminated. The contact was able to continue driving.

Torque converter failed resulting in failure of transmission. Requiring complete replacement of transmission at the cost of $7100 from dealership.

The transmission caused a vibration and sometimes a surge when it would go into gear. I had to be very careful when initially driving forward, especially in heavy traffic making sure I had a safe distance ahead of me. The entire vehicle would shutter when accelerating almost at any speed.

I have a 2018 Chevy Silverado that has issues with the transmission slipping into different gears as well as hard violent jerking even on the freeway ,and I heard hard rumbling in my transmission burnt out with only 76,000 miles, it's like they're designed to go out.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while her son was driving at an undisclosed speed, the vehicle shuddered. Additionally, the contact stated that the transmission was stuck in first gear.

My vehicle has been properly maintained since new. At around 90,000 miles the transmission started making noise. I had trans filter changed and the noise abated.

While on the Interstate with cruise control on, my truck started to vibrate while on highway, then shakes so badly it becomes difficult to grip steering wheel firmly. Slowly came to a stop and checked all four wheels. Waited on side of road until engine cooled down somewhat and then got off highway at next exit and made my way back home on side streets NOT DRIVING OVER 40-45 MPH.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving approximately 64 MPH with the cruise control engaged, the transmission became inoperable. While going up a hill, the vehicle was shifting hard in first and second gear.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving 45 MPH and approaching a stop light while slowing, the vehicle lost motive power without warning. The contact was able to restart the vehicle.

Transmission doesn’t shift smoothly and often slams into second gear from first very hard. Downshifting on rare occasions shifts to a lower gear before necessary causing rpms to go from 2800-3000 up to 4500-5000. I have to touch the gas real quick to upshift. Also brakes seem to require extra strength to engage if hard braking is required. Like the booster is not reacting properly.

The truck has has multiple issues.RR taillight always blows fuse,which I think sometimes stops my back sliding glass,I have no power to it,this has been an issue since day one,always have to carry fuses,then not long after having the truck,it has stabili trak issues,it stalls when first put into drive.delayed take off sometimes the truck jumps forward and revs the rpm’s up to 1000 X rpm sitting then it jumps to a fast hard takeoff.the truck does something called chuggel and buck I believe,it bogs way down,and then again it’ll slip buck it kicks jerks and also harshly engages.I love Chevy and haven’t given up hope just yet.this is my first Chevy.

While I'm very slowly backing up my attached small 2 wheel trailer the Transmission over heating warning light comes on. This has happened SEVERAL TIMES!!!!

Under light to medium load on the throttle, the transmission will shift very hard from 1st to 2nd gear and sometimes 2nd to 1st while decelerating. Another issue is that the transmission or torque converter will shutter, but that is not as often. It does not happen every time, but happens way more often than it should for it being a 2018 with 26k miles.

The transmission failed. The truck had heavy shifting and the transmission needs replacement. The truck was no longer safe to drive.

Transmission shifts out of gear spontaneously while driving and warning light comes on for “transmission hot idle engine” forcing the vehicle to become inoperable unexpectedly without allowing the vehicle to drive forward or reverse to get to a safe location. Transmission temperature gauge rises quickly to 280 degrees in less than an hour of normal driving before overheating.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle would not properly accelerate while depressing the accelerator pedal with the check engine warning light illuminated. Additionally, while depressing the brake pedal, the braking system malfunctioned causing the braking distance to be extended.

While driving my transmission will shudder and the vehicle will lose power causing the vehicle to slow down abruptly. It also will shift very hard making a loud noise.

Transmission noise -something loose only 60k miles

The torque converter failed internally allowing the torque converter clutch to shudder. The fluid exchange has already been done on RO#587959. Vehicle had 40k when torque converter was replaced.

While driving this truck I get a severe shudder at various speeds and now its not shifting gears correctly. I have been told there is a big problem with these 6 speed transmissions ans torque convertors.

The engine gave out at 60k miles. Only covered buy the extended warranty I bought. the transmission thunks on downshifts.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving 75 MPH, the traction control and the transmission overheating warning lights illuminated. The contact was able to park on the side of the road for 30 minutes for the transmission to cool down.

Radiator started leaking at 40,000 miles. Leaking at a weld where tube connect to side tanks.

Radiator developed a leak as described in General Motor's Service Bulletin PI1513F dated January, 2019. Safety was put at risk due to having a vehicle which could have a sudden radiator failure and permanently damage the vehicle. The Dealership I had my radiator replaced at would not state if they have had this issue occur often.

Tl* the contact owns a 2018 chevrolet silverado 1500. The contact stated that while driving approximately 55 MPH, a warning light indicating that the transmission was overheating illuminated. The contact pulled over and turned-off and restarted the vehicle and continued driving.

Failed to shift gears. Jerking and shaking. Bunning smell.

Transmission locked up and failed. Acted like it bound up. This happened during a normal shift sequence, acted tight then engine just kept over revving.

When I place the truck in drive in the morning or after the truck has been sitting for more than a few hours, the transmission engages hard, lurching the truck body foward. The dealership acknowledges the problem, but said there is no fix.

When I drive I get a hard shift/slipping when taking off and I get a hard downshift when slowing down or coming to a stop. I have taken it to the dealer and they say they fix it, return it, and same problem. When I come to a stop and am sitting for a while the vehicle begins to shake out of nowhere.

Coolant water keeps spilling from water pump. As I was driving on the freeway, the pump blew and spilled all the coolant and had to pull over to the side. Had to get it replaced paid $150 for the part and than labor another $150.

Transmission overheats when backing a trailer up a slight hill and will not move untile it cools down.

Transmission problems including slipping, shifting harshness, clunking, especially on downshifts and slipping when towing. Clunking noise/feel when slowing down/stopping. Especially noticeable on hills, but present on flat and downhill roads at surface streets as well as freeways and highways.

My vehicle is having hard downshifting issues. Mainly from 2 to 1 and occasionally from 3 to 2. I notice there isnt a recall listed but it definitely seems like a serious issue.

On 8/17/2020 I started getting a severe shaking in the front end of my 2018 chevrolet silverado crew cab 4x4 ltz. Thinking that I threw just a wheel weight I took it to my priority chevrolet in chesapeake virginia and found out it has a shutter shake as the dealership called it.

While driving on interstate towing empty 12' trailer, the engine stopped and received stabilitrack message and transmission too hot. This happened again after letting engine cool down. Had the tramission fluid changed two days later.

The plastic radiator has cracked and is leaking coolant heavily. Truck still under powertrain warranty by gm is only offering to cover 20% of the $1,823 repair cost. I noticed it when stopped to get gas, the vehicle leaking approximately 1.5 gallons of coolant while stopped for approximately 3 minutes.

When I opened doors the fuel pump turns on, while I'm driving it shifts and runs funny and you hear popping noises. The gauges mess up and radio turns on and off. Like its being hacked.

Tl* the contact owns a 2018 chevrolet silverado 1500. The contact stated that while driving approximately 35-50 MPH, the vehicle decelerated, shuddered and loss motive power. The check engine and traction control warning lights were illuminated.

Service stabilatract comes on before I start the truck still since the day I bought it the dealership does not know what's wrong. And since I bought the truck the tranny really bangs and clunks a lot it's annoying when trying to drive in stop and go traffic it gear chases way to much. It can't be good for the tranny life.

Tl* the contact owns a 2018 chevrolet silverado. The contact stated that while driving, the transmission would overheat. The air conditioner was not working and the fans were running.

At approximately 15,000 miles I was parked in a yard and blocked in so I backed up on a small hill and the truck jerked badly for about 15 feet I thought it was the positive traction trying to catch on the grass but further into driving the truck I noticed it happening more and more in forward or reverse and in shifting into gears are at times hard.

Bought this truck brand new with 9 miles on it. (previously drove a ram 1500). My first gm product I've bought in my life and I'm disgusted!

Transmission slips, knocks, and grinds in some instances. No check engine light from these issues but spent 30k + and I having these issues at 13,500 miles.

The eight speed automatic transmission stutters and acts like it doesn't know what gear to go into under light to normal acceleration. This occurs while cold and during the warming period, (normally up to around 180 degrees), but tends to resolve after the engine is completely warmed up.

Transmission is having hard shift and shutter at a speed of 60/65

Multiple Ttansmission failure, Torque Converter failure which leads to a completely destroyed transmission, vacuum pump to transmission fails which then completely destroys the transmission, transmission cooler failure which destroys said transmission. Due to parts availability, GM continues to replace with reman transmission which continues to fail. 6L80E transmission.

While driving on an Interstate the vehicle violently shook and drive shaft ce off.

Transmission failed at approximately 120,000 miles. All maintenance had been done and 90% of miles on vehicle were highway miles. Appears as though there's a thermostat mounted on the exterior of the transmission that is prone to failing around the 100,000 mile area, and when this part fails, there is no transmission fluid circulating to be cooled, so the transmission gets so hot it fails.

Transmission locked up. Vehicle has low miles.

Transmission issue!! Jerks on downshift as well RPM ramp up after shift of gear in 2nd to 1st gears

6l80 transmission out of no where started kicking in and out of gear while in busy traffic. The motor would rev up and then kick itself back into gear multiple times. This wasn’t stop and go traffic also moments later I was at a light turning left as I did the vehicle start this losing power to the transmission except this time I was in the oncoming traffic’s lane trying to turn.

Vehicle shuts off while driving in traffic at low and high speeds stabilitrak service light comes on and the vehicle dash goes dark Radio and temp control panel go dark/ black

unknow getting gas in oil at 62532 miles on it which can cause the motor to grenade. a lot of the 5.3l on 2018 has this trouble from watching utube and using research, should be recalled and transmissions trouble as well.

The truck excellerate when I stop at stop sign or red light, with my foot on brake pedal acts like it is going to take off without my foot on gas

Transmission shifts very hard in lower gears and is very sluggish at times.

Transmission issues with 78500 miles, one owner, no hauling other than a boat. headed to shop... multiple complaints on 2018 transmissions why no recall

The transmission started shifting improperly at 40k and the fluid gets to hot

The transmission stopped working randomly on the highway after being driven for 45 minutes perfectly fine. Thankfully this happened near a stoplight so the traffic on the highway was going slower than normal otherwise it could have been very bad. Local mechanic confirmed that the transmission was no good and has ordered a replacement.

The transmission clunks and slips a lot.

While driving or idling Transmission temp was around and staying at 240.

While driving highway speed on cruise control the RPM levels start jumping up and down and it feels like your driving over the rumble strips. It only last for a second or two at a time, but it does do it a good amount of times while driving.

Hard downshift from 2nd to 1st

Transmission slips, transmission downshifts hard, transmission will have a loud thud when reengaging after taking foot off gas pedal in stop and go traffic, especially on the expressway. Thud can be felt in the cab of the truck. Electronic 4 wheel drive grinds when engaged in motion.

I purchased this truck new in november of 2018. It had 4 miles on it. My previous truck I owned for 10 years.

When driving on highway transmission surges/pulsates under light acceleration. When accelerating most often when vehicle is already in motion there is a extreme delay in shifting which causes a jerk at lower speeds or an delayed then hard shift at slightly higher speeds. Most noticeable in traffic.

Transmission clunks when slowing down

This trucks transmission shifts whenever it wants to... I was driving 45mph and coasting to a red light when it downshifts hard but when the light turned green again and I pressed the accelerator I had no torque, like I was in 5th gear and should have been in 2nd. I pressed a bit harder and it downshifted hard again and was at 5k rpms!

When vehilce goes from 6 cylinders to 4 cylinders it shakes really bad and causes headaches at all speeds ! Worse at higher speeds
