| Nov 2025 | ENGINE AND ENGINE COOLING | The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving 30-40 MPH, the check engine warning light and other unknown warning lights were illuminated, and the engine was running rough. The vehicle was taken to an independent mechanic, where the contact was informed that the vehicle could not be diagnosed due to a lack of equipment. The vehicle was then taken to Gary Sapp Automotive, where it was diagnosed with engine failure. The mechanic determined that the engine needed to be taken apart for the repair or replacement. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The manufacturer was notified of the failure and informed the contact that the vehicle was not covered under an extended warranty.

| Nov 2025 | POWER TRAIN | I was stopped at a stop light and all of a sudden, the engine just revved amd revved and no drive only reverse, and it happened 4 times until tonight, 11/11/25 @ 8:38pm I am stuck at another red light and have to back my truck up to Home Depot and get a tow. Only a 5 year old truck with 71122 miles and ALWAYS WELL MAINTAINED WITH PAPERS AND GOES OUT ON ME. NOT ACCEPTABLE GM! You make things and used to be solid, like a rock trucks but now I feel robbed as a long time Chevy fan/enthusiast but I may have to change manufacturers unfortunately. | Crash: No Fire: No | Unknown |
| Nov 2025 | ENGINE | GM 6.2 engine recently tested for the national recall regarding valve and lifter issues. Recall was cleared as ok, but they found burnt cylinders in multiple areas within the engines. Several issues are still occurring with this engine, and I think most are related to the recall effort. 1. Engine will use oil at an abnormal pace when towing anything heavy. Recently used an additional 2 quarts of oil when towing a trailer that weighed 10, 000 pounds over 1600 miles. 2. Recently engine seemed to lose compression at a stop light and turned off. This happened an additional 5 times until I could get the truck off the road and into a safe place. The engine would immediately start and then die within 5-10 seconds. Towed to a Chevrolet dealership and the service manager tried to move it into the bay for diagnostic testing. started and stopped 4 additional times as they attempted to drive if 100 feet into the service bay. Towed to my hometown dealer that afternoon for diagnostics testing. The next morning when they started the truck it cranked fine and has been running since (7 days). No lights appeared on the dash during the breakdown or warnings appeared in their testing I have spoken to several other Chevrolet owners about the 6.2 engine issues and what was occurring with my truck They also had seen an increase in oil usage when towing heavy. I believe that your investigation needs to delve further into not only issues with the lifter / rods but also into other mechanical concerns that are oil dependent and related such as burnt cylinders. This last issue occurred on October 27, 2025. | Crash: No Fire: No | Unknown |

No metal found in the fluid. The issue was with the torque converter. I had my oil changed 1.5 weeks prior with a 21 point inspection. I was curious if there was a TSB for this issue.

| Oct 2025 | POWER TRAIN | I experienced a locking up or no power to the rear wheels. It was raining and the rear wheels would spin. I had no traction. I had to take a few turns and had to be careful or I would have fishtailed into other vehicles. When I stopped at a stop light/or sign then proceeded forward the rear wheels would spin in place. The tires wouldn't grab the pavement. This is the best way I could explain it. | Crash: No Fire: No | Unknown |
| Oct 2025 | UNKNOWN OR OTHER | The air conditioning only blows HOT air. The vehicle was inspected by my mechanic and states that the compressor and belt have failed and needs to be replaced. I realize that my 2020 Silverado is out of warranty, but after looking into this situation, I have found that GM has had known air conditioning issues with certain Silverado models, especially 2019-2021. I believe this is a widespread defect and should be covered and repaired through a goodwill program. I am bringing the Silverado for repairs to my mechanic on 10/31/25 as I live in South Florida and cannot continue driving this vehicle without air conditioning. | Crash: No Fire: No | Unknown |
| Oct 2025 | ELECTRICAL SYSTEM | 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 | Crash: No Fire: No | Unknown |

The failure mileage was approximately 62,265. | Crash: No Fire: No | 62,265 |

Seems very similar issue as other chevys with water intrusion. | Crash: No Fire: No | Unknown |
| Oct 2025 | POWER TRAIN,ENGINE | While driving the engine shut off without any warning lights which could have caused a serious accident causing bodily harm or property damages as I was unaware of the issue and was going 50mph at the time - this occurred on 10/23 I noticed a ticking and brought the vehicle to the dealer for inspection on 10/20, at the time of this inspection the technician said that they could not replicate the sound and I explained that this was happening at 3000 RPM. The technician said that I would need to bring the vehicle back and they would need to start to take apart my engine piece by piece and I said the ticking is part of the known lifter problem and the technician shrugged his shoulders offering no other options. That same day I took my vehicle to another independent shop and he confirmed the ticking is a known issue that occurs prior to the lifter collapsing. After the vehicle shut itself off, and I was able to restart the vehicle, many warning lights appeared on my dash, there were none there before, one of the codes that was flashing was ESC and the vehicle began to lurch and downshift. I called my mechanic who said the code was to do with the electronic stability control system but I should be okay to drive until I could get to him for him to look at the codes. On 10/24 I took the vehicle to the mechanic and another code was for Cylinder 3 misfire which he stated could be the collapse of the lifter and the codes will not clear. The vehicle now downshifts without warning, there is an engine knocking that is occurring and the vehicle is not safe to drive as the engine may seize at any moment. | Crash: No Fire: No | Unknown |
