2021 Chevrolet Silverado 1500 Electrical Problems

Your tailgate won't open, likely due to water getting into the electronic switch and causing corrosion. This is the second time it's happened to your truck, and the dealer says it could cost around $1,000 to diagnose and possibly fix. GM has issued a recall for this exact problem on 2020-2024 Silverados, and your truck should qualify since it matches the recall year and issue. The repair will likely involve replacing the corroded tailgate switch and checking the wiring harness and connectors for water damage.

Your driver's side window switch stopped working, leaving you unable to roll down the window. The dealer confirmed this was a manufacturing defect with the switch itself and repaired it. The switch replacement should resolve the issue permanently.

I just bought this truck off a used car lot certified dealer and I noticed the engine light on then the truck would hesitate to start and I know the battery is dying so I looked it up and I got a recall on 2021 Chevy Silverado just like mine just wondering why mine is not under recall or why won’t mine get fixed but everybody else is the same year in the same problems can get fixed. I think mine should be fixed.

Check engine turned on and at the same time the vehicle turned into safety mode abruptly, it slowed down to 10 miles an hour while on the high way and receiving a message stating that the "engine power reduced", the issue was presented to the dealership and they believe to be fixed with a sensor issue, the light came back on a few days after the initial repair and once again the engine lost power while driving the vehicle, the vehicle was then taken back to the dealership for repair once again, both times I mentioned the service bulletin, which they did not consider in their repair, stating that the issue was specific for a code (which all codes present are in the service bulletin) the 2nd repair was done on a actuator, which they stated should fix the issue, and did not, a 3rd time the vehicle lost power while hauling a trailer, this time I brought up the concern of them not reviewing the service bulletin, this time they confirmed that the service bulletin was the issue causing the check engine light (GM service bulletin no: 21-NA-149) now they are looking to slowly start repairing the issue and wait for the check engine light to turn on again to then go back and forth and review step by step the instructions in the bulletin.

The vehicle has an electric tailgate lock switch failure/defect. The tailgate unlocks on its own and pops open while driving, at stop lights, in drive-thru restaurants, and while parked which causes a safety hazard to the driver and passengers in the vehicle, as well as other drivers around the vehicle. Even after closing the tailgate, it will unlock and pop open on its own again. Then, I tested the closed, locked tailgate by shacking and pulling it open from the top edge which caused the tailgate to unlock and open on its own. This causes a thief risk of personal belongings and vehicle parts. There are no warning lamps or messages about the component failure. Since no recalls for the vehicle's VIN number are listed, it has not been confirmed by the dealer.

The tailgate randomly opens and closes during driving causing contents to fall out of the tailgate and creating a hazard for other motorists and damaging personal property. The tailgate now will not open and there is no manual override to open the tailgate. Certainly a design flaw and now not allowing access to the tailgate. I've contacted 5 local gm/chevrolet dealer service departments and they cannot offer any guidance on how to manually or power open the tailgate. I have a tonneau cover on the tailgate which makes it pretty much unable to access. I'm a firefighter and put my gear in the tailgate and need access asap. Please advise on how I can get GM/Chevy to assist with this issue. A police officer was behind me when the contents fell out of the tailgate on 6/9/25. This has happened several times since and most recently on 1/17/26. This needs addressed asap. Thanks!

A week or two before I took my truck into decorah Chevy isr because tailgate was going up and down all by itself while I was driving or parked without me by it. They said it was just the latch button . So they fixed it they said and still my blinker lights would just come on and then I hit a deer and my seatbelt did not latch and my airbags didn't deploy even though my app says they did. I'm wondering if all three are connected with electrical . Either way my air bags did not deploy and my truck has extensive damage and my seatbelt didn't lock ,

The vehicle has been showing a “shift to park” message error upon shutdown even though the vehicle is fully in park and door automatically unlock when parked. This has left the accessories on and drained the battery

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while the vehicle was parked, the contact was unable to remove the key from the ignition. The contact stated that several attempts were needed, and up to 45 minutes were needed to remove the key from the ignition. The vehicle was taken to the dealer, but was not diagnosed or repaired. The contact was referred to a locksmith regarding the failure. The manufacturer was made aware of the issue and referred the contact to the NHTSA Hotline for further assistance. The approximate failure mileage was 101,000.

Vehicle was at a stoplight with the auto start button engaged on it. The vehicle completely stalled. All the power is drained from the car. leaving me stranded in the highway. I got it towed and when replacing the battery still nothing will roll over or even turn on.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that upon arriving at the destination and turning off the vehicle, several attempts were needed to release the key from the ignition. The contact also had to leave the key in the ignition on several occasions because the key could not be released or removed. The vehicle originally returned to normal functionality, but the key had since become permanently stuck in the ignition. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the ignition switch. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 69,000.

This is a recurring and random issues: 1. The "Stereo" shuts off and will take anywhere from a minute to 10 minutes to come back on. The issue is: a. This cuts out the use of hands free operation. b. It stops all use of GPS c.I can no longer use my cell phone to call in an emergency 2. The backup camera (which is the "Stereo") goes blank or dark on occasion. Cannot see to the camera for backing up anymore. 3. The "Stereo" stops responding, but still has power. This means the radio or music or whatever is still playing but I cannot turn it DOWN or OFF. Very unsafe that I cannot turn this off when driving, cannot hear sirens, etc. I have tried to have this addressed by Chevrolet. They "reset" the truck but I did not work. They want to replace the "stereo/backup camera/communication system" but cannot guarantee this will actually fix the issue. It is over $2000 to "try" this fix I contacted GM customer service and was told NO RECALL, NO RECOURSE

Auto tailgate would open and shut on its own, the rear tailgate button stopped working and then only the interior switch would work, Then after a month, the tailgate would not open and switch shorted out. Seems very similar issue as other chevys with water intrusion.

While driving at anywhere from 18–25 mph or 70–85 mph, my speedometer starts going crazy, the engine accelerates or decelerates, the speedometer shows random numbers, and you can hear and feel that the motor power feels different. Not all the times but is started to show more often

The following is a list of persistent electrical failures in my vehicle, several of which present a significant safety risk. I have attempted to resolve the issues: •Emergency OnStar Button Failure: My vehicle's emergency OnStar buttons consistently fail to function when the ignition is off. This is a critical safety defect, as the system is designed to work on a backup battery during an emergency, such as a crash. The system only operates when the ignition is on. • Excessive and Dangerous Floor Hump Heat: Following a service visit on October 2, 2025, the front floor hump became excessively hot, melting personal items and posing a fire and burn risk. •Fabricated Safety Warnings: The vehicle's computer system repeatedly displays false and misleading messages. Examples include an incorrect "new brake pads detected" prompt and a "taking your eyes off the road" warning that does not apply to this vehicle. These phantom messages are distracting and can cause driver confusion. •Persistent Connectivity Failures: The vehicle experiences frequent and consistent failures with its Wi-Fi and GPS systems, indicating a potential electrical or software malfunction. Numerous resets attempted by the manufacturer's technical support have not resolved the issue. • Computer Display Anomaly: the Chevrolet symbol appeared in red on the computer screen when the truck was started. The vehicle has repeatedly experienced spontaneous changes to the radio station and the air conditioning switching from cold to hot without driver input. •Unusual Decompressing Sound: When the vehicle has been sitting for an extended period, an unusual decompressing sound can be heard coming from the rear underside whenever a door is opened. Date: Software updates on January 27, 2025 and October 2, 2025. Diagnostic Test performed on October 2, 2025 that failed to resolve the issues. The OnStar buttons only works when the vehicle is turned on. I do have photos and videos available to support your claim.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that the vehicle failed to start. The vehicle was taken to the local dealer, where it was diagnosed and determined that the battery needed to be replaced. The vehicle was repaired on two occasions, but the failure persisted. While attempting to open the trunk, the trunk failed to open. The manufacturer was not contacted. The failure mileage was approximately 500.

Tailgate experienced issues with not unlatching when button is pushed and also unlatching when button is not pushed.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving at various speeds, or while attempting to reverse, the infotainment system displayed a blank screen; however, approximately a minute later the infotainment screen displayed as intended. The contact stated that the radio became silent and then thirty seconds later the infotainment system operated as intended. A dealer was contacted. The vehicle was taken to the dealer where it was determined that the infotainment system needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 44,540.

My 2021 Silverado has the same issue as the current recall, whereas the tailgate open by itself when the vehicle is operations. This happens when it rains. The first time I noticed it I lost a cooler out of the back of my truck on the interstate highway. The second time it came down when hauling a trailer and cause minor damage to the tailgate. I have since removed the fuse that controls the tailgate. I notified Chevrolet of the issue, but the stated that my truck is not under the current recall.

Engine started making clicking noise when accelerating. Followed by a large screeching noise. Dash read "shift to neutral and start again" pulled to stop and tried to start. Does not crank at all.

Batter dies for when it's cool out side and the truck has a brand new battery. The battery has since I've had the truck .replaced the battery last year and it stills die..when it's cool outside..false reading on brakes had them checked twice at the dealer ship .the truck loses power when turning the corner and I makes a loud clunk nose when I drive..

The rear power tailgate was randomly opening and closing on its own, on several different occasions. The safety risk was, if the tailgate would have opened when traveling down the roadways, items in the back could have fell out and possibly striking another vehicle and causing an accident. The truck has been taken to Gandrud Chevrolet in Green Bay WI, confirmed there was a faulty tailgate switch and replaced. There was no warning before the switch failed, it just happened on its own.

The tailgate is opening automatically without anyone near the vehicle or keys. It has only started recently and I see similar vehicle models are being recalled for the same issue. My concern is that this could happen while driving down the road, posing a risk to other drivers if there are items in the bed of the vehicle. Prior to the tailgate opening unexpectedly, the button to push on the tailgate that opens it quit working. It will only open with the keys or button in the cab, or now at random times.

Tailgate, inadvertently opens. Causing, causing items in my truck bed to be exposed, although I haven’t lost anything while traveling. I have witnessed this occurrence while truck is locked sitting in my driveway, last incident was last night, 13 Feb 25. Also, noticed it when pulling out of a repair shop after getting brake pads put on vehicle. Wife had witnessed it a few months ago while driving back from town. I noticed a recall had been made about Chevrolet trucks and inadvertently opening tailgates. However my truck was not listed as a recall, when I checked VIN. Called Chevrolet garage to see if they could find my VIN on the recall list. Most of the recalls were on the 2500 and 3500 series but it also listed trucks with switch in cab for tailgate to open. I do have an appointment for the problem at Chevrolet garage in the 18th. To fix problem and prevent causing a hazard on the roads.

1. The automatic tailgate opens by itself randomly. It appears to be malfunctioning. I am unable to open it from the tailgate now. When it’s open it continues to attempt to unlatch making the noise. It’s opened while driving. 2. So far I lost a cooler on the highway due to this problem which would cause a road hazard to other drivers. 3. I brought it to the dealer they said it’s not there problem due to my vin not matching the recall even though there’s a recall for this problem with same year trucks. 4. It has not been inspected due it not being an official recall. 5. No warning lights regarding this issue.

I washed my truck and now suddenly the tailgate opens and closes whenever it decides and I have paint that is bubbling and it looks as if it’s gonna all chip right off the hood

UNKNOWN. PARK Switch module is not working correctly. The vehicle keeps displaying message saying the vehicle needs to be the parking position.

Push-button tailgate electrical failure. Tailgate opens on its own while driving and while truck is off. This is a known issue that has already been recalled by GM but my truck was not included in the recall, even though the problem and repair are exactly the same as the currently recalled vehicles. I had to pay a GM Dealership to make the repair as the vehicle was unsafe to drive due to potential for flying debris from the bed while driving.

Hello: I have this issue with my vehicle, and have read several people on Chevrolet Silverado message boards noting that their windshield wipers do not function properly when turned on. My wipers only work when I push the button to wash the windshield and they do not work in any other setting. I believe this is something that should be looked into and it seems like this is a good place to start.

I was driving down the highway when my tailgate open on its own. This has happened 4-5 times where items could have fallen from my truck bed and caused an accident. There is an active recall for this issue but according to my VIN my vehicle isn’t affected but it clearly is. Dealer has inspected and confirmed it’s the same issue as with other models.

There is a current recall out there for the tailgates releasing on 20-24 Chevy Silverado 2500 and 3500. I own a 1500 and am having the same issue. Water is getting into the rear electronic switch and releasing the tailgate unbeknownst to me. I have lost items that were in the bed on the pickup on the road while traveling. Can the recall include the 1500 models also?

Vehicle attempted to do an 'over the air' update to the infotainment system. This prompted an error message, stating the update failed and return to the dealership. Took vehicle to GM dealer, diagnostics were run, and dealer stated that an update was not available, and the module for the infotainment system was bad. Quoted me $1600 for replacement and install. Have read multiple reports with owners' having the same issue. Infotainment system attempts to do an update, and it fails. The owners are left paying out of pocket for something that was not their fault. This needs to be a recall. Not only are you paying a hefty amount for a repair that is not your fault, but the entire Infotainment system doesn't not work (stereo, cooling/heating info, back up camera etc)

The tailgate activates on its own, whether the truck is on or off, in motion or parked, the tailgate will activate and open at random times. There is no button that is pressed down, and no user error making this happen. When driving the vehicle, the tailgate will slam open and if you are pulling a trailer, the tailgate will slam into the trailer hitch and cause damage. Also, contents falling out of a truck bed is also a serious concern for other drivers. The truck was read for codes, and the code U0140 came up for the body control module that is malfunctioning. The truck has not been inspected by the manufacturer as of yet, but if need be, it can be arranged. The first time this error was noticed was in August 2024, and has been happening on & off since then. There were no dashboard lights on showing an issue was present when it first started and even now there are still no warning lights. Please consider issuing a recall, this is a major safety issue for other drivers.

The inner tailgate on my 21 Silverado is not functioning properly. The upper electronic button on the tailgate operates the inner tailgate and will release when opening the vehicle. It will continue to release by itself and can cause damage to the vehicle or to other vehicles while carrying a load.

Multiple times at varying speeds my 2021 Silverado has produced engine misfire codes. I have never been able to get to it quick enough to see what cylinders are misfiring so it always gives me a general P0300 code. The following first two times it was confirmed by Widrick truck and diesel in Carthage, NY. The last time it happened, the code disappeared before I would take it to the Chevy dealership. Widrick said they can’t fix the problem because they don’t know what it is, and Chevrolet denies there is a problem at all. The truck still has less than 50k miles on it

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the vehicle stalled with several unknown warning lights illuminated. The vehicle was taken to the dealer where the vehicle was diagnosed as a failure with the engine wiring harness. The contact was informed that the engine wiring harness needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The failure mileage was approximately 52,696.

In January 2024, the electric tail gate started to spontaneously open and close. This occurred while driving and in park. I took it to Outten Chevrolet in Allentown, Pa, where they stated it was a problem with a switch. They replaced it. Within a month I was told there was a problem with this model, and a recall was being planned. Over several months , I kept inquiring about the status of the recall, hoping to be reimbursed. I finally contacted Chevrolet directly. I was told that there was a recall, but my vehicles VIN number was not included. I feel that I should be reimbursed.

Electric tailgate opener button switch on tailgate failed and allowed tailgate to open while traveling. Lost a tote containing tools onto the roadway when accelerating from an intersection. Luckily it was a rural road with no traffic and no one hit tool tote in the roadway. This seems to be a serious safety hazard especially if a motorcycle would of hit lost cargo in the roadway.

My check engine light came on. When taking it to the dealership, they say it's the Catalytic converter. The converter is not an electronic part, so we replaced the o2 sensors and the check engine light came back on. I've taken this truck to several people who repairs cars, and The vehicle is only 3 years old , should not need to be replaced. A converter should last 10-15 years. In doing some Research, I found the the 2019 recalled for the ECM module. Causing the same issue as the faulty reading on a catalytic converter. I am now out of warranty due to being 2,000 miles over the limit.

Rear tail gate opens when parked and while driving. It also opens when key has been removed.

The key fobs for keyless start/lock/unlock stopped working and batteries replaced still didn’t work. Brought to dealer to be fixed. They replaced a sensor thinking it would be the fix- did not work. They found a corroded wire and replaced it. Asked them what happened and how it corroded. They said it was nothing we did wrong it just corroded. Cost $1000+ for fix for an issue that seemed to “just happen”

Back in March 2024 the tailgate opened on its own only a few times. Now April 2024 it opened on its own several times without a button being pushed. After it opened it made several clocks like the tailgate is trying to lower. Now the tailgate button does not work and can only open it with the key fob

1. Trucks start/stop delays. When in traffic or crossing over lanes the truck fails to turn back on/start. When the truck does turn back on, the truck jumped forward almost sending me and my family into on coming traffic. 2. When trying to start the truck the starter will turn over constantly not turning on the truck (motor is turning over). The starter will time out after about 20+ seconds. The starter does this when auto start/stop is activated, so we get stuck in traffic almost causing accidents.

On Sunday, January 4th, the tailgate of the truck began unlatching and opening on its own. It has done this repeatedly since that date. Only unlatches when the vehicle is in park and unlocked. The electronic latch will continue to cycle (click) after the tailgate has initially opened. Exterior taillights and side markers flash as they should with each cycle. This issue is identical to the warranty recall issued recently for the 2020 through 2024 Chevrolet and GMC 2500 & 3500 trucks.

On the evening of Dec 19th, our 2021 Chevy Silverado 1500 DuraMax with 19K miles on it caught fire, burned, and was declared a total loss. We were on our way to go pick up our travel trailer as were we leaving for a trip on Xmas with our 2 dogs and my brother-in-law. Smoke started billowing out from under the hood and within minutes the front end was engulfed in flames. I have pics/videos. We’re ok but that was a scary situation that could have had a different outcome. We could have been on the highway towing our trailer with our 2 dogs and bro-in-law and who knows how long it would have taken the fire department to arrive on scene on the highway. There were no warning lights etc. to notify us. The truck gets driven, taken care of and I had just driven it the day before. We’re not aware or have seen any recalls. All info is on our Chevy app. We filed a claim with our insurance, and it has been paid off now, but in reality, "our fault" in insurers eyes. No cause was determined. That being the case, GM has closed claim and say not liable for personal property lost in fire, as insurance didn't contact GM with any mfg defects and insurance has already paid off the truck. We are repeat Chevy customers. This was our 4th leased Silverado and we also have a Traverse. The lease on the burned-up truck was coming due May 2024. We way overpaid on the milage. We're not filing a homeowners claim for lost personal property as insurance has paid off the truck and we don't want to be dropped. My question is wouldn't this be under warranty? Should the truck not be replaced? We didn't cause the fire. Much more damage could have occurred. People and pets could have possibly been injured or worse. If we were towing our travel trailer, that would be another big loss. The truck is no longer "available". Insurance told me today it's being sold for parts, which honestly kind of scares me. I wouldn't want a truck part that was in a fire, damaged or not. Videos not attached.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving approximately 60 MPH a burning rubber odor and a smoke haze was present inside the cabin of the vehicle. After stopping to investigate under the hood flames were present at the passenger side fire wall of the engine compartment. Moments later the cabin of the vehicle was in flames which quickly spread and the entire vehicle became engulfed in flames. The fire department was called to the scene to extinguish the flames. The vehicle was destroyed and towed away. A police report and fire report were taken. The cause of failure was not determined. The manufacturer was not notified of the failure. The local dealer was contacted. The failure mileage was 90,000.

Push start button malfunctioned. The vehicle would not turn off last night and took about 30 minutes to get vehicle to turn off. Next day, had the same issue where vehicle would not start and left me stranded. After calling for a tow truck, I was able to start the vehicle. When researching the problem online, I saw several other complaints of the same issue where the buttons malfunctioned and could either not start their vehicle or turn the vehicle off.

Engine suddenly began to run rough and slowed substantially while driving. If this occurred at highway speed, it could have presented a safety risk. Multiple check engine lights and error messages appeared at the time of the event - "service emissions system" and "65mph max speed" Dealer inspected vehicle and found a shorted wiring harness and fuel injector. The faulty parts were replaced

On three separate instances (two after paying $3,000 to "fix" it) my 2021 Trailboss is flashing warnings of: Park Assist Off, Steering Assist is Reduced Drive with Care, Service 4WD, Service Trailor Brake System...all while driving down the rode and losing all gauges/flatlining and no fuel warning engaging (had a 1/2 tank). The Chevrolet Dealer claims it's not producing a code (Thankfully I recorded the evidence)...Truck has just over 40k miles and has been driven with care. **Pictures are all while driving down the road** Serious electrical and SAFETY ISSUE and it needs to be RECALLED and addressed!

Tailgate opens on its own or doesn’t want to open with push button

I bought this vehicle brand new off the lot in 2021. Truck hasn’t had any problems until this year. Every few weeks it will randomly just not want to start, I’ll usually check the battery and the battery will be completely drained. I can’t figure out what is causing the battery to drain like this, but something needs to be done as I have literally been stranded places due to my truck just deciding not to start randomly. Today i’m having this exact problem, my trucked was parked overnight in my garage and I went to go to work this morning and once again the truck won’t start and battery is drained. All my doors are shut and no interior lights are left on.

The monitor has disconnected many phone calls and rejected software updates. The monitor has been reported to the dealership and has been in many times for harness replacements, harness for the door locks and the timeframe for the repairs was a couple of weeks. The monitor still disconnects calls and I must pull the car over and restart the truck the monitor stays off sometimes until the monitor wants to engage. The history of the truck with this issue has been documented with the dealership

The 2021 LT Trail Boss with the 5.3L engine started a really rough idle, engine knocking, random misfiring, had Service Emergency Brake, Service ESC messages on the display, check engine light and several other dash warning lights. The dealer diagnosed the truck with lifter fail apart (failure), intake valve push rod bent, and PCM failure. Odometer reading 19,368 miles.

2021 Chevy Silverado durmax brought it in three times now for starting issues 2nd time found data module was bad two weeks later brought it back for same issues. Dealer said they can’t find anything wrong I’ve broke down on hwy 5 in. Dangerous spot and know I don’t feel safe driving this.

Can't pull a trailer without the SERVICE TRAILER BRAKE SYSTEM LIGHT coming on a dinging over and over. Had my trailer completely rewired only to find out its a malfunction on my truck not my trailer. My truck is a 2021 Silverado z71 trail boss with low mileage

The ESC, parking light, traction control, and engine light came on while driving home. The engine started to shake. There was an issue with braking and steering the vehicle that made it difficult to control. A message on the dash said Service ESC. A report was sent via OnStar Notifications that said An issue with the emissions system is detected. After trying to restart the vehicle a few times, the lights will not go away. The truck is driving rough.

On July 27, I encountered a failure of the rear vision display system on a 2021 Chevrolet Silverado. In short, the system used to display the rearview image went blank, and remained blank, the moment I first shifted the vehicle into reverse. Hence, no rearview image was visible while I was in the process of backing up the vehicle. I believe this may be a noncompliance with FMVSS 111 or a closely related safety defect (I worked in Safety Engineering at General Motors and Ford for a combined total of more than 30 years). I made a video to document this failure, and I uploaded it to YouTube. It is available at the following URL: https://youtu.be/zhBZwteAcBg This vehicle was provided to me as a loaner vehicle while my personal vehicle was being repaired by Quality Chevrolet in Escondido, California. Shortly after leaving the dealership, I pulled over to the side of the road and paired my cell phone with the vehicle. It took several attempts to successfully accomplish this. I then made a hands-free call and then proceeded to drive home. Within a couple miles, I decided to make a U-turn. Given the size of this vehicle, completing this U-turn required backing up. The moment I placed the transmission in reverse, the center display went blank and consequently no rearview image was displayed. Even after I shifted the transmission back to Drive, the center screen (which is also used to display other things like the radio station, time, temperature, etc.) continued to remain blank. However, the audio continued to function (noted at 1 minute and 15 seconds into the video). I decided to make a video to document the condition prior to turning off the ignition as my experience has been that such malfunctions are likely associated with software errors that can be difficult to track down and replicate. I drove this loaner vehicle several other times before returning it to the dealer. On each occasion, the rearview image displayed when the vehicle was put in Reverse.

Car Fire - Started at the rear of the cabin between the cabin rear window and the truck bed The fire engulfed directly around and inside the fuel tank. The car is available for inspection as far as im aware at the tow / salvage yard The safety of myself and any passengers were greatly put at risk. The fire engulfed the inside cabin within seconds, and caused a total loss on the car. The problem has not been identified elsewhere. However the almost exact scenario has occurred in the manufacturers other 2021 model vehicles on the Tahoe and Yukon, with recalls on file for both for incorrect seal around the fuel tank, causing fuel tank fires. The car manufacturer does not want to help at all, they are willing to deal with insurance company and that is it, who will just pay out the value of the car. The police and fire crew local to the incident have ran reports on the fire. No warning lamps occurred before or during the fire. The car was operating as normal until the large explosion. There was no accident, nothing was hit, witnesses described small embers / flames flying up from the truck bed right before the big explosion, indicating there was fuel spitting out and catching on fire.

Driver side front marker light bulb not working after 700mi. Not a big problem but annoying enough for a 2 week old, $49,000 truck.

ON THURSDAY FEB 18TH IS WAS SNOWING WHEN I LEFT WORK, DROVE AROUND THE BELTWAY APPROXIMATELY 30 MILES GOING ON AVERAGE 30-40 MPH.NO ISSUES JUST BAD ROADS. RIGHT AFTER I LEFT THE HIGHWAY AND TURNED ON TO A MAIN ROAD, I WAS APPROXIMATELY 1 MILE ON THAT ROAD IN THE MIDDLE LANE DRIVING STRAIGHT AT ABOUT 25-30 MPH WHEN MY NEW 2021 SILVERADO (5000 MILES) LOSS POWER. THE BATTERY AND CHECK ENGINE LIGHT CAME ON WITH NO ENGINE POWER. AS THE VEHICLE WAS COASTING ATTEMPTED TO GET OFF THE MAIN ROAD, BUT DIDN'T MAKE IT DUE TO THE SNOW COVERED ROADS AND SLUSH. ENDED UP IN A MERGE LANE STILL IN TRAFFIC AND WAS ALMOST HIT NUMEROUS TIMES. TRIED TO RESTART AND GET TO A SAFE LOCATION, BUT WHEN PUSHING THE START BUTTON THE SILVERADO WOULD CRANK EXTREMELY LONG PERIOD OF TIME AND THEN FINAL CUTOUT. WAS ON THE PHONE WITH ON STAR WHERE THEY PUT ME IN CONTACT WITH THE LOCAL POLICE DEPARTMENT WHO NEVER SHOWED AND THEN LEFT ME A MESSAGE THEY WERE COMING OUT DUE TO THE INCLEMENT WEATHER. THANKS. AFTER TALKING WITH POLICE DISPATCH ON STAR SETUP A TOW TRUCK, BUT GAVE THEM THE WRONG ADDRESS WHICH WAS MORE THAN AN HOUR AWAY FROM MY LOCATION. ONCE BACK ON THE PHONE ON STAR STATED THEY HAD TO CALL THE SAME TOW TRUCK DRIVER/COMPANY WHICH OF COURSE HE WAS OVER AN HOUR AWAY. ONCE THE TOW TRUCK DRIVER ARRIVED 3 HOURS AFTER MY TRUCK BROKE DOWN HE SAID HE WAS ORIGINALLY ONLY 10 MINUTES FROM MY LOCATION PRIOR TO ON STAR SENDING HIM TO THE WRONG LOCATION. WHAT A MESS. HAVE A LOANER CAR BECAUSE I HAVE BEEN TOLD A FUEL PUMP IS ON NATIONAL BACKORDER. ALSO THAT THEY WILL BE REPLACING THE VALVE SPRINGS WHICH IS ANOTHER ISSUE I THINK? HOPING TO KNOW MORE THIS WEEK.

INFOTAINMENT SYSTEM DOES NOT WORK ALL THE TIME. XM RADIO HAS NO SOUND AT ALL, OR AS I AM DRIVING DOWN THE ROAD THE XM RADIO VULUME ON ITS OWN GOES SO LOW YOU CAN NOT HEAR IT AND THEN YOU CAN NOT TURN IT UP OR DOWN WITH THE VOLUME CONTROL ON THE DASH OR THE ONE ON THE STEERING WHEEL. TO CORRECT THIS ISSUE ONE HAS TO TAKE THIER EYES OFF THE ROAD AND USE THIER PHONE IF IT IS PAIRED WITH THE SYSTEM OR TURN THE RADIO TO FM OR AM. AFTER DOING THIS THE VOLUME CONTROL WORKS ON XM.
