1st incident My son was driving the truck when all the emergency lights came on. He pulled over and the engine was on fire. He ran to a strangers house to get buckets of water not safe for my child at all. Come to find out that an engine rod slipped and put three holes through the engine causing oil to spill and a fire unbelievable! Lucky my son wasn’t injured. Chevy blames my son for that!

My 2021 Chevrolet Equinox, VIN [XXX] , previously showed an active recall related to fuel system and stalling issues. The recall no longer appears under my VIN, but the same dangerous symptoms are happening. The vehicle jerks during acceleration, hesitates, loses power, and stalls while driving. These problems create a major safety concern because the vehicle can suddenly lose power in traffic. T

I am requesting that the vehicle be inspected for recall-related failures, warranty coverage, special coverage adjustments, or goodwill assistance due to the safety risk involved. I would like documentation showing whether the recall repair was previously completed on this VIN and whether any warranty remains on the repaired or replaced parts.

What component or system failed or malfunctioned, and is it available for inspection upon request? Engine seized and vehicle was towed to dealership. It is available for inspection. How was your safety or the safety of others put at risk? Loss of propulstion, described below. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, dealership where originally
... purchased. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Inspected at dealership by GM/Chevrolet technician. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None prior to failure Detailed description: On 5/21/2026, during normal driving, the engine in my truck lost propulsion due to a major internal failure. This is a 2023 General Motors 6.2L (L87) engine that was inspected at the dealership where it was originally purchased for the previously issued NHTSA "loss of propulsion" recall and passed without any noted issues. This engine only has ~20,000 miles on it. The engine failed in relatively heavy traffic and could have easily resulted in a serious accident due to inability to route my vehicle to a safe area while under power. This all happened without any prior warning, no check engine lights, noises or lamps or symptoms. The dash simply illuminated with a "Press Start" message.The truck was towed to the dealer for evaluation. The dealer called me today (5/26/2026) stating the engine was seized and a new engine would have to be ordered from GM for installation. This event occurred while the vehicle (2023 Silverado ZR2) is still under the original 36 month/36,000 mile warranty.Read more

The pedal was very hard to press, and when pressing with all my weight, I could slow the vehicle to a stop, but it took a great distance.

While traveling at 55mph yesterday, I experienced a full engine failure which shut the car off fully while traveling on a single lane double yellow road. I was able to coast to a secure location.

The contact owned a 2015 Chevrolet Tahoe and stated that while driving, the vehicle's doors locked and unlocked randomly, the cabin lights flickered, and the doors failed to unlock properly during entry attempts, while the radio randomly selected its own options and the touchscreen occasionally stopped working despite the alternator and battery being replaced. Furthermore, the vehicle suddenly and
... randomly lost motive power and shut off on main roads, highways, and at stop signs, which caused the dashboard to flash on and off and the power steering to fail completely. When attempting to turn off the vehicle by twisting the key, it refused to shut down initially and triggered a large engine bay fan to kick on, though replacing the temperature gauges eventually resolved this specific shutdown issue. The vehicle has been taken to multiple dealers and independent mechanics, but was failed to be diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure.

I own a 2015 Chevrolet Silverado equipped with a GM V8 engine that experienced significant engine failure symptoms consistent with known GM engine defect issues and related recall/service campaign concerns. Prior to failure, the vehicle began exhibiting abnormal engine noises, warning lights, performance issues, and symptoms indicating internal engine damage. The condition worsened and resulted i
... n major engine failure requiring extensive repair or engine replacement. The failure created safety concerns due to the potential for sudden loss of power and loss of propulsion while driving. Based on the symptoms, model year, and engine configuration, I believe the failure may be related to known GM engine issues involving internal engine components, lifter failures, AFM/DOD system failures, bearing damage, or related defects that have been the subject of recalls, special coverage adjustments, technical service bulletins, or investigations affecting GM trucks and SUVs. I believe the vehicle should qualify for coverage, repair assistance, recall-related repairs, or special policy consideration from General Motors due to the nature of the engine failure and the known history of similar failures affecting comparable GM vehicles. I am requesting that GM review the vehicle history, diagnostics, and failure condition to determine eligibility for recall coverage, special coverage adjustment, warranty assistance, or reimbursement related to the engine failure.Read more

After doing research online, this problem is affecting all years of the 2019+ blazers with the 3.6L V6 engine AND other known problems with other models and years of their other lineup of cars, it’s very widespread across their platforms.

While driving my 2021 Chevrolet Silverado 1500 Trail Boss, multiple warning lights and messages suddenly appeared related to the ABS and brake system. The brake pedal became extremely difficult to press and the truck became unsafe to drive. The issue happened unexpectedly while the vehicle was in operation, creating a serious safety hazard and risk of accident or injury. After the incident, the t

I was also informed that the condition and quality of the braking components were not acceptable for a vehicle of this age. This vehicle is only five years old and has been regularly maintained. For approximately the last three years, routine maintenance including oil changes, tire rotations, and inspections were performed at a Chevrolet dealership. At no time was I warned of any brake-related issue or safety concern. A major brake system failure should not occur suddenly on a properly maintained vehicle, especially without warning. This incident was extremely dangerous and could have resulted in a serious crash. I am submitting this complaint because I am concerned there may be a defect involving the brake system, brake booster, ABS system, or related components on this vehicle.Read more
