| Apr 2025 | VEHICLE SPEED CONTROL,ENGINE | Driving vehicle down freeway about 75mph heard noise and truck shut speeds down to about 60mph on a major freeway. Per mechanic lifter has collapsed and it has been a common issue that Chevy knows about. He said that it could have been alot worse by seizing the engine and causing harm to drive or other people around causing a major accident. There is a major safety issue to life and or death caused by this issue that has NOT been a concern and causing people to pay over $5000.00 for repairs. Chevy has known about the faulty lifters for years and doesn't seem to care about safety concerns. | Crash: No Fire: No | Unknown |
| Apr 2025 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | On Feb 10, 2025 while in busy mid-day traffic on the highway going 55mph my vehicle without any warning signs or warning messages on dash, or dash indicator lights suddenly went into limp mode , began making a loud knocking from the engine, and started shutting down. I stopped the vehicle as soon as I safely could do so and had it towed back to the selling dealer for them to diagnose the issue. The dealer then informed me that i had a bent lifter on the left bank but they did this based on codes and not any tear down. They referred me to another local dealer. I had my vehicle towed there where they also stated lifter. Once they began to replace the lifters on the left bank scarring was found on my #3 cylinder wall and at that point I was told that my truck had catastrophic engine failure and the engine would have to be replaced. They also told me that my truck had no oil in it and the issue was caused from carbon build up. I have had every maintenance service performed on time and at the selling dealer and have all service records. I was not overdue on maintenance. I have never been told about any oil leaks or any other issues that needed to be resolved on my vehicle. I had driven the truck the night before with no issues.. There was no oil on the ground or under the vehicle for them to say there was no oil in the vehicle. I was never told that i needed spark plugs due to carbon. I believe that this has to due with the AFM issue that GM is well aware of. I had to purchase another vehicle due to the damage that was found on this required an engine replacement | Crash: No Fire: No | Unknown |

| Apr 2025 | VEHICLE SPEED CONTROL,ENGINE | Component/system that failed: The transmission control module in my 2020 Chevrolet Silverado 1500 has malfunctioned. The vehicle has issues with slipping between gears, rough shifting, and hesitation when accelerating. This component has already been inspected and diagnosed by a certified Chevrolet dealership, and the part is currently on backorder. The vehicle is available for further inspection upon request. Safety risk: This issue poses a serious safety risk to myself and others. The gear slipping and delayed response when driving—especially when merging onto highways or changing lanes—creates unpredictable behavior that can lead to an accident. The truck sometimes fails to engage gears properly, which makes it dangerous in traffic situations. Diagnosis confirmation: Yes, the problem has been confirmed by a Chevy dealership service advisor (Jose Diaz), who provided a formal quote and diagnosis for the replacement of the transmission control module. Inspection by others: The vehicle has not been inspected by police or insurance representatives, but Chevrolet Customer Assistance is currently reviewing the case, and I was advised to submit this documentation. Warning lamps or symptoms: There were no warning lamps initially, Symptoms include slipping gears, hesitation when pressing the gas pedal, jerky shifting, and difficulty accelerating smoothly. These symptoms have progressively worsened over time. Additional context: I have learned that many 2020 Chevrolet Silverado trucks have been recalled for the exact same issue, but my VIN is currently not included. I believe this is a manufacturing defect and that my vehicle should be considered for inclusion in the recall or further investigation. | Crash: No Fire: No | Unknown |
