The tailgate on the truck popped open without being triggered to. This continued to happen like every 5-10 seconds. It drained the battery and was a hazard as I drive down the road.

An electrical component related to the vehicle's rear sliding glass window and rear defroster malfunctioned and overheated, causing smoke to fill the cabin of the truck as it was being driven down a busy highway. Immediately following the smoke, the rear window violently shattered due to overheating from the malfunction. This dangerous defect was known to exist in our model and year of truck, as documented in customer satisfaction program n192265660. This bulletin shows that gm knew about this exact issue, yet allowed the vehicle to be sold and driven. This incident was incredibly dangerous and easily could have caused my wife (who was driving) to crash the vehicle due to limited sight and distraction. My wife called me following this incident and was terrified and confused. There were no warnings, signs, or symptoms suggesting an issue with the electrical component until the incident occurred. We immediately contacted gm, who advised we were not permitted to get the vehicle fixed until they completed their inspection; however, it has been nearly a week and no inspection has occurred at this time.

This complaint is submitted as additional information related to a previously filed safety complaint for the same vehicle and incident. Since the original submission, general motors product assistance claims verbally denied responsibility, refused to inspect the vehicle, refused to provide written confirmation of their denial, and ceased responding to emails and calls. Gm previously instructed me not to repair the vehicle and promised a rental vehicle and tow, neither of which were provided. The vehicle remains unsafe to drive due to smoke intrusion and shattered rear glass and has been left exposed to freezing and rainy conditions. This incident appears consistent with a known rear window defroster thermal defect similar to gm customer satisfaction program n192265660. Gm’s refusal to inspect or mitigate increases safety risk.

Rear window defrosted heated up so hi my window exploded.

Dear sir or madam, I am writing to formally report a safety-related defect involving the power unlatching tailgate switch on my Chevrolet 1500 truck and to request that this make and model be added to the current safety recall affecting chevy hd vehicles. The power tailgate unlatching switch malfunctioned and would repeatedly attempt to open and close the tailgate while the truck was parked. On one occasion, this occurred continuously overnight. The following morning, my key fob was completely unresponsive, and the truck had zero battery life. The battery would not accept a charge, and the vehicle had to be towed to the dealership. Upon inspection, the dealership confirmed that the battery had been fully depleted and permanently damaged due to a short in the power tailgate switch. The faulty switch continuously drew power as it attempted to actuate the tailgate, ultimately destroying the battery. This failure created a serious safety and reliability concern, leaving me stranded with a completely inoperable vehicle. Given that this issue resulted from an electrical short and caused total battery failure, I believe it represents a significant safety defect. Based on the similarity to issues addressed in the current chevy hd safety recall, I strongly believe this make and model should be included in that recall. I respectfully request that this matter be reviewed and addressed to prevent other owners from experiencing the same hazardous situation. Thank you for your time and attention to this matter. I look forward to your response. Sincerely, charles senn.

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.

Vehicle has less then 700 miles. Upon driving vehicle, the dashboard started losing information, no speedometer. When I tried to pull the truck over to the side of the road, the power steering was lost. It was nearly impossible to turn the wheel, then the engine stopped. I was unable to turn on blinkers or hazard warning lights. When I put the vehicle in park to try a restart the engine would not turn over. The transmission was locked in park and unable to shift to neutral to try to push vehicle to safe spot. At this point I was blocking the road. Called for roadside assistance, two hours later vehicle was towed to Chevrolet dealership, were it is being assessed.

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.

At 150 miles on the odemeter the tpm light came on I pulled off the highway, got out and checked all 4 tires. Not noticing any issues I got back on the highway and turned on the stereo. The speakers sounded like they were blown apart. Static and the sound of muffled vibrations. I drove to my intended destination and turned off the truck. After finishing my business at this location I started the truck and the tpm light was not iluminated. This is a hige safty issue. As a firefighter paramedic I have personally seen dead and mulated people that stoped on the highway and got out to check there vehicle and were struck by another vehicle. This issue is going to cause people to immeadiatly stop and get out of there vehicle thinking there is a flat tire. There is obviously a computer glitch in the 2026 cheverolet Silverado 1500 series.

While driving the vehicle the tailgate came open by itself. I had left my house and when I arrived at my friend’s house to pick him up the tailgate was down. I closed the tailgate and while driving a driver honked their horn to alert me that something was wrong. When I pulled off the road the tailgate had come open for a second time.

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.

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 ,.

Tail gate has water intrusion and opens on it own. I was charge over $200 to have this issue looked at that I was told was a recall. Turns out my vehicle is not listed on the recall yet and was not advised before being charged.

Transmission/ignition. Can not lock vehicle and battery will die. When turning the ignition to off, dash message 'shift to park' appears. Must turn ignition on and off repeatedly to get it to go out. Dealership tried tightening a plug but it did not work.

The contact owns a 2022 Chevrolet Silverado 1500. The stated that while the vehicle was parked, the tailgate opened independently, and the tailgate was manually closed. The contact stated that the next time after stepping out the vehicle, the tailgate opened independently. The contact stated that the failure persisted. The contact stated that when the vehicle was started the tailgate was down, and the hazard light flashed. Most recently, the vehicle failed to start. The contact realized that the battery had failed to function as intended. The contact associated that the failure was a possible short circuit from the tailgate. The contact disconnected the battery. The vehicle was taken to the dealer, where it was diagnosed and determined that the tailgate switch had failed and caused the battery to drain. The vehicle remained at the dealer pending the repair. The manufacturer was not notified of the failure. The failure mileage was approximately 59,000.

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 -30°f to -50°f 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).

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the tailgate was constantly opening unintendedly. The failure also occurred while the vehicle was parked overnight, causing the battery to drain. Additionally, the contact stated that the rearview camera was inoperable. The vehicle was taken to the dealer, where it was diagnosed, and determined that the tailgate switch and rearview camera had failed due to water intrusion. The dealer replaced the tailgate switch; however, the rearview camera was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 38,000.

Was taking an exit car felt like lose control and got hit with the sign pole on the exit. I have been complaining for the safety reasons and the location and other issues in car to onstar and chevy for months. Went to freeport chevy dealer and changed oil, when I bought the car pre-approved but the when I went for the service they said no oil was changed since the car was new. And I have been paying for all the warranty and extended service but they said all oil change and others will cost approx $3200. They changed the oil but I have been seeing on the chevy app filter was never changed and the car didn’t feel same after the service.

Fuel pump control module failed and vehicle is available for inspection upon request. Cell [xxx] truck engine shut down twice on interstate 10 eastbound in TX at interstate speeds, in heavy traffic causing dangerous threat to my family and I while powerlessly navigating between high speed traffic and 18 wheelers to exit road independent service center?yes and independent. Code read on truck's computer confirmed a failed fuel pump control module the vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others? there were no warning lamps, messages or other symptoms of the problem prior to the failure. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving at highway speeds, multiple warning lights illuminated on the dashboard at the same time, including engine and powertrain warnings. The vehicle suddenly began operating abnormally, with loss of power and unstable driving behavior, making it unsafe to continue driving. This same issue has occurred multiple times previously and the vehicle has been taken to an authorized Chevrolet dealership for repairs on three separate occasions. Each time, repairs were performed, but the problem returned. The most recent incident occurred while driving on the highway and created a serious safety risk to the driver and other vehicles. The vehicle is not safe to drive.

My transmission blew up and I almost wrecked my truck. No engine lights came on, and still no engine lights are coming on it only has 69,000 miles on it and has never missed a service. Its currently at the dealership where I bought it from.

1- tailgate keeps opening by itself. It has opened while driving down the highway and things fell out of back of my truck almost causing an accident. It has opened while sitting in my driveway after I have turned the truck off and gone inside. I have reported this to a dealer they said my VIN is not on the recall list. I would like my VIN added since it is obviously an issue with the silverado's. 2- I recently has to bring my truck to the dealer for the transfer case sounding like there were bolts in a blended and a pinging sound by the bell housing while in park. They stated it was the front axle and fixed it saying it was a power train thing. The noise is back and now out of warranty.

Trailer brake warning.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the vehicle was repaired under NHTSA campaign number: 25v274000 (engine and engine cooling), but the failure occurred. The contact was informed by the dealer that the vehicle had passed inspection, and the dealer added a higher viscosity oil, installed 6 oil fill caps, and replaced the oil filter. The contact stated that six months after the vehicle was repaired, there was an abnormal squeaking sound coming from the engine. The contact stopped at a gas station to refuel. Afterwards, the vehicle failed to restart, and there was smoke coming from under the hood. The contact stated that the engine had seized. The contact was at the gas station when the failure occurred. The vehicle was towed to a dealer; however, no cause for the engine failure was found. The contact was informed that the sound was coming from one of the drive belts. The vehicle was not repaired. The vehicle was then towed to another dealer, where it was diagnosed and determined that the abnormal sound was coming from loose bearings in the engine. The contact was informed that the engine needed to be replaced. The long block in the engine and the radiator were replaced on January 1st. The contact stated that a week after the vehicle was repaired, the vehicle failed to start. After several attempts, the vehicle restarted. The vehicle was taken back to the dealer. However, no cause for the failure was found. The dealer recharged the battery. The contact stated that shortly afterwards, the vehicle failed to start. The vehicle was taken back to the dealer, where it was diagnosed and determined that the starter had failed. The contact requested that the dealer check the ground strap, but the dealer refused. The vehicle remained at the dealer unrepaired. The contact stated that the dealer would notify the manufacturer of the failure. The approximate failure mileage was 44,469.

Unknown, esc , traction control, service brake. The truck stop and those 2 codes shows and is on but doesn’t it move.

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 2022 Chevrolet Silverado 1500. The contact stated that while driving at 65 mph, the vehicle vibrated and failed to accelerate as intended while depressing the accelerator pedal. Additionally, the vehicle failed to exceed 40 mph. The contact was able to pull over into a rest area. The power tailgate and power windows failed to function as intended, and the vehicle failed to restart. The message low battery power was displayed on the instrument panel. The contact attempted to jumpstart the vehicle however, the vehicle failed to restart. The vehicle was towed to the dealer, where metal shavings were found in the oil pan and oil filter, which caused the engine to fail. The contact was informed that there was a hole in the radiator. The manufacturer was made aware of the failure and paid for the engine replacement. The vehicle was repaired. The contact stated that days after retrieving the vehicle, the radio became inoperable. The contact stated that while the turn signal was activated, there was no sound, and the light on the onstar button failed to illuminate as intended, and the WI-fi intermittently failed to operate as intended. Most recently, the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the telematic module had failed. The vehicle remained at the dealer unrepaired. The manufacturer was made aware of the failure. The failure mileage was approximately 52,000.

The telematics module on my car stopped working. It caused all of my warning tones to go out and are not audible. Furthermore the onstar system is not working. I have read a lot of post and it seems like the module is a high fail item and if it fails after the manufactures warranty then we are left with a pretty hefty bill just to get one of the safety features to work. Gm needs to fix this at their expense given the amount of modules that have failed in the past few years on newer vehicles.

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.

The problem that happened on my truck was the telecommunication module went out at 45k miles. That controls several features on my truck such as compass, navigation, remote start from cell phone, clock and several others. The biggest problem is that a check engine light pops up and you cant use your key fob to remote start your truck since the check engine light is on. I took it to the gm dealer to get fixed and they had to replace the module. According to my service advisor this is a common problem and I am looking for a recall or more information into why it failed.

Driving home 2 blocks from my house when truck stalled completely no power would not start total black out. Resembles recall campaign number14v614000.
