2020 Chevrolet Silverado 1500 Electrical Problems

While driving home from work the truck displayed numerous trouble codes including ebc failure, braking failure, traction control failure and trailer brake failure as well as vehicle governed to 42 mph. I took it to the dealership and they checked all of the braking system and could not find any issues. They reset the codes, and changed all 4 pads and rotors as all 4 wheels were 1/32 out of true as a precaution. I drove it home about 5 miles with no issues. The next morning I was on my way to work and the codes reappeared with me being governed to 62 mph. At the stop sign I had no braking at all. Pumping the brakes resulted in no braking or pressure in the pedal. Luckily there was no traffic and I was able to use a hill to stop. I turned around and went the mile back to my house and was unable to stop again ending up with the front end in my neighbors yard. I had the vehicle towed back to the dealership where they still have not found a cause or a solution to the issue

The contact owns a 2020 Chevrolet Silverado. The contact stated that while the vehicle was parked, turned off, and unoccupied, the rear of the vehicle caught fire. The fire was initially extinguished by a maintenance worker, and the fire department later applied water to the area to prevent the fire from reigniting. The fire department was unable to determine the cause of the fire, and a fire report was not provided. The contact was unaware whether a police report was filed. The vehicle was not destroyed or towed. The vehicle was taken to a dealer, where it was diagnosed that the rear wiring harness had failed and needed to be replaced. The dealer also informed the contact that the rear bumper and tailgate were damaged as a result of the failure and would need to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was not available.

The component that failed was the wiring harness installed in the engine area. the harness was installed right next to a dip stick. The dip stick has a sharp metal piece welded to it and it punctured the harness cutting wires on the inside. This could have been a potential fire hazard. The problem was able to be reproduced, inspected and confirmed by a certified chevy mechanic at Philips Chevy in Frankfort, IL. The mechanic also showed me the failure point on the vehicle upon a visit. The dashboard lights were flashing randomly, headlights were very dim which it very difficult to see, android auto stopped working and not able to use hands free, so that became a safety issue, cruise control stopped working, and was receiving errors for a failed fuel pump.

The contact owns a 2020 Chevrolet Silverado 1500. While operating in negative (-41°F) degree winter conditions, the "Service Emission System" entered an EPA-mandated speed limitation in LIMP Mode messages were displayed. Dealer diagnostics confirmed DTC: P20B9 (Heater Control Circuit Open) and P20C1. The failure was identified as the melting of the Diesel Exhaust Fluid (DEF) tank electrical connector due to undersized terminal pins overheating (Joule heating). The contact stated that it was a latent design defect that posed a fire risk and a safety hazard due to sudden loss of motive power in arctic climates (-45°F). General Motors acknowledged the defect in 2500HD models, Special Coverage: N212342980; but excluded the 1500 models. The failure mileage was 29,354.

What happened: In mid-December 2025, my 2020 Silverado 1500 (VIN: [XXX] ) suffered a catastrophic failure of the DEF Tank Assembly (P/N 84914535) at 29,354 miles—less than 30% of its warranted life. This is a latent design defect involving undersized terminal pins that suffer thermal degradation and melt the connector during high-amperage heater operation in arctic conditions (Ref: GM TSB 21-NA-006). Component Availability: The failed assembly is held at the dealership. I have submitted a "Part Preservation Request" to ensure it is available for forensic inspection by federal regulators. Safety Risk: The failure triggers an EPA-mandated "Limp Mode," initiating a software-forced reduction in speed. Unexpectedly losing speed on high-speed, icy Alaskan highways—where roadside snowbanks prevent safe egress—creates an extreme risk of rear-end collisions. Furthermore, a vehicle restricted to 5 MPH or rendered inoperable in temperatures of -30F to -50F poses a direct, life-threatening risk of cold-weather exposure in remote areas. Confirmation: Failure was confirmed by Lithia Chevrolet GMC of Fairbanks on Jan 7, 2026. GDS2 diagnostic verified DTCs P20B9, P20C1, P205D, and P204C. Data was reviewed by the GM District Manager of Aftersales (DMA) and GM Customer Assistance (Case #[XXX]). Warning Symptoms: Check Engine lamp and "Service Emission System" message appeared in mid-Dec 2025, followed by a "Speed Limited" countdown. The electrical disconnect was abrupt due to terminal pin melting, as documented in my forensic engineering report. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving it said "service ESC", "brake system failure" and then "trailer brake system failure" "max speed 62." Brakes when pressed would not work. Had to cruise to stop. When truck shut down and restarted it said "max speed 43" and check engine light came on. Truck was then towed to mechanic and waiting to be looked at/worked on.

There was a brake system failure and the brakes stopped working while going 50 mph

Engine idling rough shaking stalling loss of power

Truck experienced reduce power mode. Took to have codes ran and it showed 24 separate codes when engine light comes on. While riding down the road, truck will go into reduce power mode, shift automatically into 4x4, and several other notifications will appear. Taking to dealership and was told the electrical wiring harness was shorting out causing this issue. Cost around $700 for repair, happened one month later, took it back and no charge for the 2nd time. It is currently in reduced power now. Dealership stated to replace the wiring harness would cost over $3,000. Dealership stated this was a manufactures defect, but no recall was issued so all cost is on the owner.

Shop has had the truck over two months and cannot figure out the problem will not go stuck in limp mode.

There is an issue with the wiring harness that causes vehicle to lose power. Dealership says manufacturer defect because designed with harness cover is too thin and is to close to engine so burns wires. Many other users have complained of this issue and is frequent in this model.

Odometer Fraud. The contact was attempting to purchase a 2020 Chevrolet Silverado 1500. The contact stated that while attempting to obtain a loan from the bank for the vehicle, it was discovered that there was a mileage discrepancy after obtaining a Carfax report. The vehicle was a private sale. At the time of the initial inquiry on Facebook Marketplace, the vehicle mileage was 63,000. The contact discovered that the mileage was 203,000.

Vehicle started and behaved as expected when leaving my home and for a dozen lights or so between my home and place of the incident. While stopped at a red light, the auto stop function shut the truck down as normal. On re-start when getting green light, after releasing brake pressure, the start up was belabored for two turnovers before starting up. As I pulled off the stop with a green light, the dash lights illuminated and display started rolling through system failures, one of which was the brakes system and ESC. I cautiously proceeded through my turn to a thankfully quiet intersection as the brakes were completely unresponsive. I had ZERO brake function. I was able to slowly come to a rolling stop enough to get the truck in park where I turned it off and back on and the brake function returned. I cautiously drove to the local chevy dealer where I was informed that the battery drain pulls from low voltage when it needs extra power for start up. This is utterly terrifying that it is even possible for the battery to start the truck WITHOUT ANY BRAKE FUNCTION. Had this happened just two lights before or after where I was, it would have been a news headline. I could have easily been headed up and over a bridge leading to a catastrophic event at the bottom where I would have been completely unable to stop my truck by any means other than a collision. I would have preferred a dead battery at a red light. Seems a whole lot safer. I'm now stressed beyond measure at the thought of some failure in the future that could lead to another event such as this. My truck is now a nightmare wondering what electrical malfunction is going to put me and/or my wife and daughter in a life or death situation, let alone others on the road. This shouldn't even be an option for the truck to start at the expense of a critical safety function. Not to mention there is no function for the auto start stop system to be deactivated permanently by my choice. I am beside myself and scared to drive.

The contact owned a 2020 Chevrolet Silverado 1500. The contact stated that while stopped at a stop light, he observed smoke emanating from the area of the vehicle between the cab and the bed, prompting him and the other occupants to quickly evacuate. Within moments, the vehicle caught fire and was engulfed in flames. Local emergency services arrived and were able to extinguish the fire. The contact was informed that fire investigators on scene determined that the fire had appeared to originate in the electrical system associated with the seat belt located behind the rear passenger side seat. No warning lights were illuminated. The vehicle was towed to a tow yard and was likely to be deemed a total loss by the contact's insurance provider. A fire report was filed. A police report was filed, and no injuries were reported. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 19V814000 (Seat Belts); the VIN was included, but the vehicle had already been repaired. The manufacturer was not notified of the failure. The failure mileage was 100,000.

I’m reporting a safety concern involving a 2020 Chevrolet Silverado 1500 with the 3.0L Duramax diesel engine. The vehicle went into limp mode and died on the side of the road. AAA installed a new battery, which temporarily restored operation, though the “Service Charging System” warning remained. I drove it home, let it sit for several days, and then took it to a Chevrolet dealership. Although the warning light had cleared, I brought it in out of caution. The first dealer diagnosed a failed alternator and recommended replacement at a cost of $2,158.75. I was also told the vehicle was not included in any active recalls related to this issue. Believing the price was high and wanting a second opinion, I went to another Chevrolet dealer. They ran the same diagnostic and found no issue with the alternator or generator, charging only a diagnostic fee. They also said if the alternator had needed replacement, the cost would have been around $1,300. I mentioned to both dealers that I had seen similar alternator/charging system failures recalled on other 2020 Silverado models. Online forums and customer complaints suggest that many Silverado 1500 trucks with the 3.0L Duramax are experiencing similar problems, indicating a potentially broader issue. Given the inconsistency in diagnostics, the significant cost discrepancy, and the number of similar consumer reports, I believe this issue may be more widespread than current recalls reflect. I respectfully request that NHTSA investigate whether the existing recall should be expanded or if a new recall should be issued for 2020 Silverado 1500 models equipped with the 3.0L Duramax. This issue occurred shortly after a separate failure related to the NOx sensor, which I am submitting under a separate complaint.

My 2020 Silverado duramax was at the dealer for recall , next day check engine light came on and rear wheels got locked up , the dealer installed new transmission valve , next day same problem check engine light and rear wheels locked up again, now the dealer said is something to be with a speed sensor and I have to paid for it , my truck was perfectly working before all this recall thing, it’s been 3 weeks now with no transportation, because GM and Chevy dealer don’t want to respond or fix this problem with the transmission valve and transmission control module software that was installed My truck was all good before this matter

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at approximately 15-20 MPH, the message “Engine Power Reduced” was displayed on the instrument panel, and the vehicle started shaking and decelerating. The vehicle was taken to the dealer who diagnosed that the engine wiring harness needed to be replaced. The dealer informed the contact that another part needed to be replaced; however, the contact was unable to recall the exact part. The vehicle was not repaired. The manufacturer was informed of the failure and informed the contact of a possible number for assistance. The manufacturer had opened a case regarding the failure. The failure mileage was approximately 124,000.

My break system failed twice in 2 weeks. On Feb 01, 2025 around 5:35 pm, I almost ran over a dog the first time because I lost access to breaks and emergency breaks and could not stop going through my neighborhood. Today on Feb 13, 2025, I had picked my son up from school, and the breaks went out after we left the school. This time I almost ran into a car but had to turn off to the right to avoid hitting it. My son and I could have injured the person driving in front of us and ourselves. I looked up the problem, and it seems that many others have faced the same problem. When I turned off the truck for 10 minutes, the system would reset itself and start working normally again. I took the truck to the shop, and it is currently there so they can run tests on it. I recorded what it looks like on the dash when I lose all braking.

Vehicle has been in and out of service for the past 5 months with multiple alerts including "Brake system failure 43mph top speed," "service esc," "service brake assist." On major interstate car would not accelerate past 43mph putting myself, infant, toddler, and wife in danger. Multiple attempts have been made to repair the vehicle and nothing has been successful. Lifters, CAM, torque converter, EBCM, master cylinder, calipers, and the list goes on. When this happens the brake is extremely hard to press making it difficult to stop the vehicle. Issue has been reproduced by dealer and attempts have been made under warranty to repair. Car only has 36k miles on it and the issue began prior to that. GM ongoing solution is to bleed the brakes, which clearly has not resolved the issue. Still hear ticking and noises from engine. Something needs to be done to remedy this issue. This is a safety hazard for myself, my family, and everyone driving around me.

While changing a blown fuse for the instrument cluster, my truck unexpectedly caught fire, endangering my safety and causing significant damage to the vehicle. The fire started behind the passengers side fuse box within the wiring harness (GM# 84717166). The dealership determined that the failure was due to wire harness chafing on the thread side of a tie bar bolt. Due to General Motors not responding to their request for repair information via the TAC, they concluded that the bolt needed to be shorten in order to reduce the chafing. There were no warning signs or indications that this was going to or could occur. The burnt harness is available for inspection but the vehicle has been traded in due to no longer trusting how it was manufactured.

While driving 55+mph on a parkway the service parking brake, check engine light and the traction control light came on with a warning "Engine Power Reduced" which was dangerous because I could not accelerate and there was not a spot to pull over. This is frustrating due to the fact that I was having this same issue 6 months ago and Chevrolet said it was a wiring issue and it wasn't covered by the warranty because it had 42k miles. Chevrolet said it was a known issue but it was not at the level of a recall and it cost $1800 to fix.

Our 2020 Chevy 1500 Trail Boss was waiting for an ordered instrument cluster at service department. The surveillance camera, film the vehicle catch on fire after being parked for 2 days. The smoke started from the inside, and the vehicle engulfed in flames until the fire department came. After the fire was extinguished very little was left of the vehicle. Basically a frame and engine was the only thing left. The vehicle had a little over 70k miles.

While driving brakes failed and codes came on saying brake system failure 43 mph, this problem apparently is a programming issue that will cost over 600 dollars because “reprogramming” isn’t covered. Brake pads were over 50% life and it is a very dangerous error.

A/C blower motor over heated and caught the electrical wires on fire under the dash. I had just left my house for work about 1 mile from home and the dash started smoking then a fire started under the passenger side glovebox parked the car in the middle of the street and I was able to exit the vehicle and put the fire out with a half bottle of water I had in the car. I then called 911 and I believe it was EAST Pierce fire department. They shortly arrived and confirmed it was an electrical fire and that there was no more heat coming from it. The fire department then gave me A ride home. The vehicle has been towed to Sunset Chevrolet in Sumner Washington where the Vehicle was purchased New in 2020.

The trucks installed trailer wiring can cause a traffic accident. The wiring harness is known to have electrical issues but is not being corrected under warranty. It is difficult to know of these issues until you hook up a trailer or camper. The trailer's brake light and turn signal are affected by the faulty wiring. The dealer narrowed the problem to being between the plug and fuse. Other people have voiced their concerns with the trailer wiring.

When you try and start the truck, the instrument panel lights up fully but when you push to start the instrument panel dims and acts like the battery is dead and won’t crank. The engine light is on. After a few presses, it finally cranks and starts fully. Has happened repeatedly and randomly.

Brake system failure reported on screen. Extremely hard to stop vehicle.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at undisclosed speeds, the instrument cluster became inoperable and failed to provide correct information. The contact stated that the alternator cable was loose and intermittently failed to operate as designed. There were no warning lights illuminated. The contact called the local dealer and was informed there were no open recalls on the VIN. The vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The contact stated that the failure was related to the NHTSA Campaign Number: 19V888000 (Electrical System). The failure mileage was approximately 19,000.

Check engine light came on. Authorized Dealer Advisor stated "vehicle may shut-off or not start." Took to Authorized Dealer. Dealer found Evap System Error Code P0499. Dealer replaced Evap Valve Harness Connector. Approximately 48hrs Check Engine Light came on again. Will schedule service with Authorized Dealer.

Already paid for transmission repair and now paying for engine wiring harness. Service update was sent out to dealer in May of 2020 to fix issues before selling vehicle. That was not done.

dash gauge cluster - ALL gauges drop to "zero" while driving speed, oil pressure, engine temp, fuel, etc., a/c compressor stops working but blower still works

2020 Silverado 1500 LTZ, Turn signals on mirror do not work

Electrical acutated tailgate will not come down. The truck came with a soft bed cover that locks. If my child was to hide in the bed somehow it would pose an immediate risk to life and health as the tailgate will not come down and does not have any type of manual override. The interior controls do not work to lower the tailgate, the key fob controls do not work to lower the tailgate.

Purchased the truck through CARMAX and two weeks later received the “Service Brake Assist” and “Brake System Failure” message on the Console. This has happened twice in in one month.

The infotainment screen brightness is set too high, such that turning the brightness setting down enough for the infotainment screen to not be too bright turns the backlighting on the instrument cluster down to where it's almost unreadable. In this specific case I was trying to use Apple Maps through Carplay for navigation in an unfamiliar rural area, where lighting on the roads is almost inexistent besides in towns. During the day it's not too much of an issue, but any time between dusk and dawn one must make a choice between visibility out the windshield and being able to quickly read anything on the instrument cluster. It is my opinion that this issue is enough of a safety hazard to force GM to make changes, but unfortunately isn't the most egregious "feature" of this screen. That title belongs to what happens when you put the vehicle in reverse at night. It seems whoever designed it thought the view of the backup camera on the infotainment screen is the only thing you should be able to see, since it changes the brightness back to its daytime setting. This makes seeing out of the vehicle in any direction where the screen is even slightly in your view almost impossible. It also means you must wait a second or two for your eyes to adjust if you want to, for example, look at the backup camera on the screen then look out the rear window. In my case, even looking out the rear window into a garage with a light on was difficult after looking at the backup camera view. Add to all of this any kind of vision issues like needing prescription glasses or contacts, and your eyes are constantly trying to adjust between being able to see what your next turn might be and being able to read any signage that may be present. Simply put, it seems GM took the idea of making the vehicle a rolling smart device to be the primary use, even above having the ability to see where you're going safely.

- My back up camera developed a fish eye distortion. - It makes it hard to see how close something is behind you, making it dangerous backing up with children in the area. - Yes, although the dealer is trying to claim it is ''normal'', even though it was not that way when I bought the truck, or I would not have purchased it. - There were no warning lamps or other symptoms prior to the problem. It appeared before 2,500 miles were on my vehicle.

The contact owned a 2020 Chevrolet Silverado 2500. The contact stated the seat heater was disengaged but failed to respond, causing the seat to remain hot. There were no warning lights illuminated. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The contact stated the failure had been reoccurring. The contact stated while the vehicle was parked and running, she heard an abnormal popping sound coming from the vehicle, as she turned around, she noticed smoke coming out of the vehicle. The contact stated a fire had started underneath the driver seat and she was able to extinguish it with the assistance of emergency units. The contact stated she sustained mild burns on her hands and arms but did not seek medical assistance. A police report was not filed. The vehicle was towed to a tow lot, where it was totaled. The dealer was notified of the failure. The manufacturer was notified of the failure and did not provide any assistance. The approximate failure mileage was 5000.

The radio continuously keeps blacking out turning off and back on over and over. Radio has been replaced and everything and it’s still an issue.

Momentary loss of electrical power going over bumps, stabilitrak warning then complete loss of cabin power, engine power and power steering. Corrects after approx 1 sec.

While driving all warnings lights came on and all gage needles started moving back and forth.

At least 3 times while driving the entire radio and information system has shut down while driving and completely gone black for 2-3 minutes and reset to factory reset This does not show as recall but worried that it may shut down vehicle completely Have told dealership during routine maintenance and they said they find no problem Obviously there is a reason this is happening

INFOTAINMENT SYSTEM RANDOMLY SHUTS DOWN COMPLETELY(SCREEN TURNS OFF ALONG WITH ALL AUDIO AND CONNECTED DEVICES). ALSO THE USB PORT REFUSES TO CONNECT AND/OR RANDOMLY DISCONNECTS ITEMS ATTACHED TO IT. THIS HAPPENS WHILE THE VEHICLE IS STOPPED OR IN MOTION. IT HAS DONE IT ON THE HIGHWAYS, FREEWAYS, INTERSTATES, CITY STREETS, COUNTRY ROADS, DIRT TRAILS, MY WORKS PRIVATE PROPERTY, EVERYWHERE IN SHORT. HAPPENS ON HOT SUMMER DAYS AND COLD WINTER NIGHTS. ITS 100% RANDOM. CHEVY KNOWS OF THE ISSUE BUT HAS REFUSED TO FIX FOR MORE THAN A YEAR NOW.

THIS TRUCK HAS 2700 MILES ON IT. GOT IN TO DRIVE IT HOME FROM THE STORE TODAY AND THE SERVICE ENGINE LIGHT IS ON. SAYS STABILITRAK ERROR AND ANTILOCK BRAKE ERROR. BRAKE PEDAL FELT STRANGE SO I WAS AFRAID TO DRIVE IT AFTER READING SIMILAR STORIES ABOUT TRUCKS VEERING OR NOT BRAKING WHEN THE PEDAL IS DEPRESSED. CALLED DEALER TO SCHEDULE SERVICE. THIS TRUCK HASN'T EVEN HAD ITS FIRST OIL CHANGE YET AND ALREADY HAVING ELECTRICAL PROBLEMS.

BATTERY KEEPS DISCHARGING. MAKING SURE NO LIGHTS LEFT ON IN VEHICLE. TOTALLY DRAINED BATTERY IN JUST 3-4 DAYS WITHOUT CRANKING OR MOVING. AFTER RECHARGE CRANKED NORMALLY

MY WIFE GOT INTO AN ACCIDENT WHERE SHE REAR ENDED FORD FIESTA AND HIT IT SO HARD THAT VEHICLE PUSHED A 2006 DODGE FULL SIZE PICKUP 100 FEET DOWN THE STREET AND THE AIRBAGS DIDN'T DEPLOY

BACKUP CAMERA ONLY IS FUNCTIONAL IN PERFECT WEATHER CONDITIONS. IF IT'S DARK WITH NO LIGHT, THE CAMERA HAS RESOLUTION SIMILAR TO A 1950 TUBE TV. IF IT'S RAINY OR CLOUDY, THE BACKUP CAMERA IS NOT FUNCTIONAL EITHER. THERE ARE NUMEROUS YELLOW LINES AND EXTREMELY POOR QUALITY PICTURE IN MANY OTHER CONDITIONS TOO. CHEVY HAS NOT DONE ANYTHING TO FIX THIS ISSUE IN MY TRUCK. THE VISIBILITY IS SO BAD I HIT MY TRAILER HITCH ON THE BUMPER 7' OFF OF MY HITCH LOCATION. I COULDN'T SEE THAT MY TRAILER WAS THAT CLOSE TO ME ON THE SCREEN

THIS TRUCK IS 2 MONTHS OLD AND ONLY HAS 2300 MILES ON IT. ON SUNDAY 12/27, THE TRUCK WOULD NOT START. ALL DASH PANEL AND LIGHT INDICATOR WARNINGS CAME ON INCLUDING 4 WHEEL DRIVE ASSIST FAILURE, BRAKE SYSTEM FAILURE, TPS FAILURE, CHECK ENGINE, BATTERY ERROR, ETC. AFTER JUMP STARTING THE BATTERY, THE TRUCK TURNED ON BUT THE CHECK ENGINE LIGHT STAYED ON ALL DAY. ON MONDAY 12/28, THE TRUCK DID NOT START AGAIN HOWEVER, THIS TIME, NO INDICATOR LIGHTS, DASH PANEL OR ANYTHING CAME ON AND I WAS ALSO UNABLE TO EVEN LOCK THE TRUCK. IT WAS TOWED TO THE DEALERSHIP AND AFTER 2 DAYS THEY STILL HAVE NOT FOUND THE PROBLEM WITH THE TRUCK ALTHOUGH THEY HAVE INDICATED THERE IS A CLEAR PROBLEM. THE TRUCK IS STILL CURRENTLY AT THE DEALERSHIP.

1ST OCCURRENCE, 9840 MILES- SLOWING TO STOP SIGN, ABOUT 10MPH, TRUCK JUMPED VIOLENTLY, FELT LIKE I WAS REAR-ENDED. SERVICE PARKING BRAKE, SERVICE ESC, TRACTION CONTROL OFF MESSAGES AND CEL ON. STUCK IN GEAR. RESTARTED TRUCK, RESUMED NORMAL OPERATION BUT CEL REMAINED. 2ND OCCURRENCE, 9865 MILES - 65MPH ON HIGHWAY GOING AROUND CURVE, TRUCK JUMPED VIOLENTLY CAUSING REAR END TO BREAK FREE SLIGHTLY, THOUGH I KEPT CONTROL. TRANSMISSION NOW SEVERAL GEARS LOWER AND STUCK THERE, TURNING 2400 RPM AT 65MPH. SAME THREE WARNING MESSAGES AND CEL. TRIED MANUAL TRANSMISSION MODE, BUT IT DISPLAYED NO GEAR INDICATION, AND THE +/- BUTTONS DID NOTHING. PULLED OFF HIGHWAY, RESTARTED, ALL MESSAGES WENT AWAY, CEL REMAINED. TRUCK RESUMED NORMAL OPERATION. 3RD OCCURRENCE, 9905 MILES (ON THE WAY TO THE DEALER) - I WAS STOPPED AT TRAFFIC LIGHT, FIRST IN A STRING OF CARS. LIGHT TURNED GREEN, I STARTED TO ACCELERATE, JUST INTO THE INTERSECTION, TRUCK JUMPED VIOLENTLY, SAME WARNING MESSAGES, STILL HAD THE CEL FROM THE LAST TIME. TRUCK WAS NOW STUCK IN A HIGHER GEAR, COULD BARELY GET THROUGH INTERSECTION. VEHICLE BEHIND ME NARROWLY MISSED REAR-ENDING ME, AND OTHERS WERE BLOWING HORNS AS I LIMPED TO THE FAR SIDE OF INTERSECTION. THIS IS A MASSIVE SAFETY CONCERN. IF ANY OF THE ABOVE SCENARIOS HAD OCCURRED ON SNOWY/ICY ROADS, I COULD HAVE INJURED OR KILLED SOMEONE, INCLUDING MYSELF AND/OR MY [XXX] YEAR-OLD. DEALER REPLACED TCM, BUT IS STILL NOTING "LOSS OF COMMUNICATION" CODES BEING GENERATED. A CHEVY ENGINEER HAS REQUESTED THEM TO INVESTIGATE THE WIRE HARNESS FOR DAMAGE IN A PARTICULAR LOCATION, SUGGESTING CHEVY KNOWS OF A MANUFACTURING ISSUE. IF THAT'S SO, AND CHEVY HASN'T ISSUED A RECALL - OR EVEN A TSB - THEN THIS POSES A STRONG CASE FOR NEGLIGENCE ON THEIR PART. ARE THEY WAITING FOR SOMEONE TO GET INJURED OR DIE BEFORE ACTING ON THIS? I'VE NOW BEEN WITHOUT THE TRUCK FOR 10 DAYS. PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

RADIO AND DASHBOARD ELECTRONICS SHUTOFF COMPLETELY WHILE DRIVING AND THEN WILL COME BACK ON A MINUTE LATER! LOOSES ALL CONNECTIONS TO PHONE, MAPS, BLUETOOTH ETC...., THEN OUT OF THE BLUE TODAY THE AIRBAG LIGHT AND SERVICE SAFETY RESTRAINT SYSTEM WARNING CAME ON! THIS IS SO DANGEROUS AND IS GOING TO CAUSE ME TO HAVE A WRECK!

BACKUP CAMERA IS COMPLETELY WASHED OUT AT NIGHT AND DURING THE DAY IS FUZZY AND OUT OF FOCUS. DEALER SAYS THIS IS NORMAL. ITS A SAFETY ITS A SAFETY HAZARD TO ME.

I HAVE A 2020 SILVERADO 1500 LT TRAIL BOSS WITH JUST OVER 5000 MILES ON IT WITH ONE PREVIOUS RECALL WHICH WAS COMPLETED. ON THIS OCCASION I WAS TRAVELING ON THE HIGHWAY AT ROUGHLY 65MPH WHEN ALERT SOUNDS CAME ON FOLLOWED BY A MESSAGE ON THE CLUSTER SAYING TO SHIFT THE VEHICLE TO NEUTRAL AND PUSH START BUTTON. I DID THAT AND THERE WAS NO RESPONSE. I WAS IN THE FAST LANE AND DID NOT HAVE ENOUGH SPEED TO GET TO SHOULDER SO I PULLED TO CENTER TURN LANE OF HIGHWAY TO STOP. I ATTEMPTED TO START THE VEHICLE SEVERAL TIMES OVER 5-10 MINUTES WITH NO RESPONSE. CLUSTER GAUGES WOULD CYCLE LIKE WHEN VEHICLE IS STARTED, BUT IT DID NOT ENGAGE THE STARTER. I ALSO TRIED TO REMOTE START FROM KEY FOB WITH SAME RESPONSE. THERE WAS TRAFFIC TRAVELING AT HIGH SPEED IN OPPOSING DIRECTION ON EITHER SIDE SO IT WAS UNSAFE TO INSPECT THE VEHICLE. I USED ONSTAR TO GET ROADSIDE ASSISTANCE AND ABOUT 15 MIN LATER POLICE SHOWED UP TO PROVIDE ASSISTANCE. ONSTAR SAID IT WOULD BE CLOSE TO AN HOUR FOR A TOW, BUT POLICE GOT ME ONE ABOUT 15 MINUTES LATER. LUCKILY TEXAS COPS ARE PRETTY COOL SO WE JUST HUNG OUT UNTIL TOW TRUCK ARRIVED.

TL* THE CONTACT OWNS A 2020 CHEVROLET SILVERADO 1500. THE CONTACT STATED THAT THE BACK OVER PREVENTION CAMERA FAILED TO FUNCTION AS DESIGNED. THE VEHICLE WAS TAKEN TO ANDERSON CHEVROLET (31201 AUTO CENTER DR, LAKE ELSINORE, CA 92530), AND THE CONTACT WAS INFORMED THAT THE INFOTAINMENT SYSTEM WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE CONTACT STATED THAT THE VEHICLE WAS NEW AND THAT THE VEHICLE WAS TAKEN TO THE DEALER FOR THE RUNNING BOARD AND THAT THE VEHICLE REMAINED AT THE DEALER. THE CONTACT STATED THAT THE DEALER DECLINED TO EXCHANGE THE VEHICLE FOR ANOTHER VEHICLE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 100. THE VIN WAS NOT AVAILABLE.

INOPERABLE INFOTAINMENT SYSTEM / BACKUP CAMERA / RADIO / ONSTAR. UPON STARTING VEHICLE, SCREEN STAYS BLACK AND NONE OF THE AFOREMENTIONED SYSTEMS WILL OPERATE.

THIS VEHICLE WAS DELIVERED TO ME IN LATE MARCH 2020. NEW SMYRNA BEACH CHEVROLET SOLD ME TWO FAULTY VEHICLES. THE FIRST THEY TOOK BACK AND NOW THIS SECOND VEHICLES BACK UP CAMERA WORKS INTERMITTENTLY FROM DAY ONE. GM NOR THE DEALER SHIP CAN LOCATE THE REPLACEMENT PART AND THIS HAS BEEN ON-GOING FOR 3 MONTHS NOW. I DO NOT FEEL SAFE DRIVING A VEHICLE THAT HAS A FAULTY CAMERA. I FEAR THAT AS A RESULT, BODILY INJURY COULD RESULT TO SOMEONE ELSE. GM HAS FAILED TO GIVE ME AN ETA ON THE PART, FAILED TO PUT ME IN A LOANER VEHICLE, AND FAILED TO RESOLVE THE PROBLEM BY OFFERING ADEQUATE TRADE ASSISTANCE TO GET ME INTO A WORKING VEHICLE.

DEAD BATTERY AT 1400 MILES... NO WARNINGS AND NO LIGHTS LEFT ON, NO EXCUSES!
