The worst model year for it is 2014.
What component or system failed or malfunctioned, and is it available for inspection upon request? The A/C condenser and the vehicle battery failed. The failed components are available for inspection upon request. How was your safety or the safety of others put at risk? The A/C failure causes the driver's side to blow warm air, creating severe window fogging and reducing visibility in extreme weather, while the electrical/battery failure compromises vehicle operation and safety features. Has the problem been reproduced or confirmed by a dealer or independent service center? The A/C issue matches General Motors Technical Service Bulletin PIT5767A, caused by an internally bypassing condenser due to a mispositioned block-off plate. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has not yet been officially inspected by a manufacturer representative, but the defect aligns with known GM manufacturing specifications under bulletin PIT5767A. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Symptoms appeared suddenly with the air conditioning losing performance (driver's side blowing significantly warmer than the passenger side) alongside concurrent battery and electrical system failures.

Several times, while driving, the truck will simply shut down. It will becoime difficult to steer, then the engine will stall, killing the rest of the steering and the breaks as well as the dashboard, radio, etc. This can happen at any speed, low speed especially. I will give you an approximate date below, but there have been several incidents. The truck was looked at by our local mechanice, who could not find a problem and by the dealership electrical specialist who has also been unable to locate a problem.

NHTSA complaint #11763787 — an unverified report by a vehicle owner.
My 2021 Chevrolet Silverado 1500 RST with the 6.2L engine experienced an engine seizure. The engine was replaced by a Chevrolet dealership under a GM safety recall. Immediately after picking up the vehicle following the recall engine replacement, the truck stalled while still in the Chevrolet dealership parking lot. There was no warning before this first stall. We continued our trip because we did not realize at the time that the stall could indicate a problem following the engine replacement. During the drive from [XXX] to [XXX], the problem continued. In [XXX], the check engine light illuminated and the truck began malfunctioning. The vehicle subsequently stalled again. The problem continued after returning to [XXX]. A Chevrolet dealership in [XXX] inspected the vehicle and reproduced/confirmed a problem involving the camshaft position sensor wiring/connector. The dealership demonstrated the problem by manipulating the connector/wiring and recorded a video of the diagnostic procedure. The vehicle is currently at the Chevrolet dealership and is available for inspection. The affected component should also be available for inspection because it has not yet been repaired. The [XXX] dealership has characterized the wiring/connector condition as normal wear. However, the first stall occurred immediately after the GM recall engine replacement, while the vehicle was still on the repairing Chevrolet dealership's property. Unexpected engine stalling creates a serious safety risk because the vehicle can lose propulsion without warning while driving, including at highway speeds or in traffic. I am concerned that the camshaft position circuit/wiring/connector problem may be associated with the recall engine replacement procedure or replacement engine. I am requesting that NHTSA investigate whether other vehicles receiving this GM 6.2L engine recall remedy have experienced similar camshaft position circuit failures or unexpected stalling after engine repair.

NHTSA complaint #11763216 — an unverified report by a vehicle owner.
Body to frame ground cables corroded in half two different times within about 6 months. First time engine wouldn’t start had to have it towed to dealer for repair, over 30 codes were shown when this happened. Next incident some of my lights were working intermittently and my steering was rendered inoperable for 20 to 30 seconds at a time making it impossible to steer the vehicle, several codes were found when this happened, I drove the truck to a Chevrolet dealer for repair. Both repairs were deemed to be corroded ground cables. Chevrolet has a “customer appreciation program” covering 2019-2024 Silverado trucks but for some reason my VIN number doesn’t land in the program even though it has the same issues that are covered for the other silverados.

I notice that check engine light went on with TC, parking brake service , some pad lock ( dont know what the ped lock is). 2nd time this happen the parking light service light went on and the brakes locked up again in traffic. 0
NHTSA complaint #11762475 — an unverified report by a vehicle owner.
The automatic power-unlatching tailgate assembly failed. The tailgate unlatches, opens, and cycles closed completely on its own while the vehicle is in motion and driving on public roads and when the gear shifts from drive to park and park to drive. The vehicle and the tailgate assembly are fully available for inspection upon request. The tailgate opening unpredictably while driving at road speeds creates an extreme safety hazard. It risks cargo flying out into traffic, which could cause a severe multi-vehicle accident or injure pedestrians. Additionally, it creates a massive driver distraction while trying to monitor the opening and closing tailgate in the rearview mirror while maintaining control of the vehicle. Sometimes there isn’t a warning light and sometimes it shows a warning light “tailgate open” I have taken it to the dealership and was told it isn’t part of the active recall for similar makes and models and my vehicles year/make/model needs to be added to the current recall for these concerns. It opened on its own while in park and turned off when the mechanic was replacing the license plate light.
NHTSA complaint #11762348 — an unverified report by a vehicle owner.
Twice under 3200 miles while pulling into driveway on an incline the vehicle shifted to neutral then turned off and began to roll backwards down my driveway. No codes or CEL came on the display read press start to restart engine so I did that and it started and ran normally until it happened again while pulling into driveway. I took vehicle to my local chevy dealer they pulled history codes and saw 8 communication error codes with various areas of vehicle, checked battery and charging, test drove it and said they found nothing wrong with vehicle. This is a safety issue and should be investigated further, very disappointing on a brand new vehicle only 3 months old.
NHTSA complaint #11762231 — an unverified report by a vehicle owner.
The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that the vehicle experienced various intermittent electrical failures while driving at various speeds. The contact stated that the power locks and windows either failed to operate as needed or independently operated while driving. The vehicle was inspected by a friend, and a potential issue with the ground fault cable was found. The friend recommended that a dealer inspect the vehicle. The contact stated that the instrument panel intermittently displayed the messages, "Steering Column Lock Needs Service", "Check Engine", and other unknown messages. Additionally, the brake pedal depressed to the floorboard while attempting to start the vehicle but resumed normal operation after the vehicle was started. The vehicle was taken to a dealer but has not yet been diagnosed or repaired. The failure mileage was approximately 80,000.
NHTSA complaint #11761890 — an unverified report by a vehicle owner.
While stopped at a highway red light, the vehicle jolted forward and numerous dash lights came on, including messages saying “Brake System Failure, Service ESC, Service Trailer Brake, Service Parking Brake, Engine Power Reduced, Power Steering Reduced.” This is the first time any of these messages have ever appeared. This made the vehicle incredibly difficult to steer and the braking ability was almost non-existent. Had this happened one minute earlier or later, a multi-vehicle and potentially fatal accident would likely have occurred. Vehicle was towed to a dealer who confirmed the error messages and severely reduced performance. To me, this seems consistent with GM service bulletins PIT5730 and 20-NA-073. The dealer, however, is quoting me $3,700 to repair the master cylinder and electronic control braking module. Whatever the case, this absolutely needs to be upgraded to a recall before this happens to somebody at the wrong time.
NHTSA complaint #11761729 — an unverified report by a vehicle owner.
The contact owns a 2025 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, there was an abnormal odor inside the vehicle. The contact stated that water was coming from underneath the driver’s side dashboard. Additionally, the steering wheel was jerking while the lane assist feature was activated; however, the vehicle was not veering to the left or right side of the lane. No warning light was illuminated. The vehicle was taken to a local dealer where it was diagnosed, and several failure codes were retrieved, and a water test was performed; however, the failure could not be duplicated. The vehicle was repaired; however, while the contact's husband was driving at an undisclosed speed, there was an abnormal sound coming from the vehicle. The driver pulled over to the shoulder of the road, and after selecting the 2WD feature, the 4WD feature was disengaging, even though the 4WD warning light was not illuminated. The vehicle was taken to another local dealer, Chevrolet of Troy (1375 S Market St, Troy, OH 45373) for a second opinion. The contact was informed that DTC: U1611 was retrieved, and several unknown repairs were needed. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 23,000.

NHTSA complaint #11761203 — an unverified report by a vehicle owner.
I applied brake and pedal went straight to floor without any stopping. I had to steer into a ditch to avoid a collision resulting in more damage to steering system, frame, windshield and body. This was complete brake system failure and yes is available for inspection. I was in a very rural area at time and was able to avoid a collision however, if I had been in city or on highway it could have easily resulted in injury or fatalities. The problem is currently under federal investigation and has been widely reported as a serious problem which may soon result in widespread recall. The vehicle has not been inspected yet by dealership or anywhere else as it just happened 18 hours ago. There were no warning lights or chimes before the incident when pedal went to the floor. After incident dashboard lit up with warning lights including, Brake, ABS, Traction control, power steering, Collision system, Engine light, Steering Column and others. Truck speed limited to 43 mph. And pedal still goes to the floor without applying brakes.
NHTSA complaint #11761308 — an unverified report by a vehicle owner.
This vehicle is a 2024 Chevrolet Silverado 1500 featuring a 6.2L V8 engine and a 10 speed transmission, currently at 58,136 miles. The vehicle was experiencing a severe shudder. An official GM Technical Assistance Case (TAC) engineering case was opened on July 30, 2026 confirming a verified DFM cylinder deactivation or valve train malfunction. However, on August 21, 2026 the dealership falsified the repair log by printing ‘Concern Not Duplicated’ to the manufacturer, while physically installing an unapproved aftermarket Range Technology DFM Eliminator module into the vehicle’s engine harness to artificially override the factory emissions and cylinder deactivation programming to mask the mechanical failure. This vehicle is part of the active NHTSA Engineer Analysis EA26005, and the manufacturer’s dealer network is actively using unapproved third party hardware shortcuts to evade mandatory warranty repairs before the vehicle’s 60,000 mile factory powertrain limit expires. I called GM to report and request a warranty freeze and regional field engineer to go to a different dealership and was told they can’t freeze a warranty because the TAC was closed on August 28, 2026 as resolved even though it was not resolved.
NHTSA complaint #11761073 — an unverified report by a vehicle owner.
Purchased vehicle in August of 2025 and there was an open recall for engine issues at that time. Took vehicle back to dealership in October or November for dealer to inspect. The vehicle passed the engine test and oil was changed to a heavier weight. From October/November 2025 I’ve been noting that there’s been a significant loss of engine oil prior to scheduled maintenance that requires anywhere between 4-5quart top off every three months or so. Feels like the vehicle is sluggish and has no “get-up”. Also, the Auto Emergency Brake light/system keeps malfunctioning. Even after it’s been replaced several times the light comes back on and you’re not able to control the forward collision gauge.

Check engine light repeatedly comes on. Take it in, multiple Chevy dealerships “fix” the errors such as fuel line pump 5x, gear shift issues, modules that went bad and various other issues. I Routinely take care of vehicle (oil changes, tire rotations and service when needed) This truck will randomly shut off while driving (stop and go traffic ) I was told to turn off the start/stop which I do every time I get in the truck. However it recently wouldn’t turn over after going through a car wash, it would try and try till I manually stopped it. It’s running rough now and I pray everyday the check engine light doesn’t come on or that it doesn't just shut off mid drive. This truck has been hell on wheels and I bought it with 10 miles on it. Bought it from AutoNation in 12/2023.
NHTSA complaint #11760615 — an unverified report by a vehicle owner.
On July 22, 2026 took truck to dealership for oil change and reported getting random (trailer brake, power steering) service alarms. Was told it might be a ground strap issue and was sent on my way. After investigating, there is a GM service bulletin (#23-NA-201) on the issue but does not cover my truck. After a week of vacation, began driving truck again and alarms became more frequent, including loss of power steering and jerking of steering wheel while driving. Arranged with dealership to replace the ground strap (at my expense). By the time they could schedule, the alarms were constant and the truck had completely lost power steering. One of the power steering failures nearly resulted in an accident while turning.
NHTSA complaint #11760322 — an unverified report by a vehicle owner.
The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that the infotainment center intermittently went black, and there was water leaking into the vehicle through the top and lower center of the front windshield and the rear windshield. The vehicle was taken to a dealer, where the rear windshield was replaced without a diagnostic being performed; however, the failures persisted. Additionally, the side view mirrors intermittently failed to unfold when starting the vehicle. The contact stated that while driving approximately 40 MPH, white smoke emitted from the exhaust, the vehicle hesitated, and it lost power. The Check Engine warning light illuminated, along with "Service Electronic Stability Control", "Trailer Brake System", "Steering Assist Reduced", "Service Brake Assist", and "Brake System Failure" messages, and the vehicle failed to exceed 40 MPH. The vehicle was towed to a second dealer, Arcadia Chevrolet Buick (210 S Brevard Ave, Arcadia, FL 34266), where it was diagnosed that the lifter and torque converter had failed. The lifter and torque converter were replaced, and the system was flushed. Approximately 800 miles later, the engine failed again. The vehicle was towed to an independent mechanic, who diagnosed that the torque converter and transmission had fractured. The torque converter and transmission were replaced; however, the warning lights and messages illuminated again, and the vehicle continued to hesitate when driven over 42 MPH. After being parked for a few days, the warning lights were no longer illuminated and the mirrors opened, but the engine hesitation persisted. The vehicle was not further diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 10,000.
