CHEVROLET Complaints

Vehicle was recalled for loss of propulsion.Pico test was done ,changed oil.6,000 miles later engine locked up on freeway.Engine is in for replacement.2022 suburban 6.2 liter 66,000 miles

My 2025 Chevy Silverado 1500 6.2L V8 experienced an internal engine failure at approximately 16,500 miles, requiring replacement of the entire long block under the factory powertrain warranty. The authorized Chevrolet dealership diagnosed internal cylinder wall scoring, and the engine could not be repaired. The failed engine should still be available for inspection if requested. About 4,000 miles after my last oil change, while the Oil Life Monitor still showed about 50% remaining, the vehicle repeatedly displayed "Engine Oil Level Low" warnings. I checked the oil level with the engine cold, and the dipstick showed the level was normal, so I believed the problem was a faulty oil level sensor. The next day, the warning changed to "Add Engine Oil," and I immediately took the truck to the dealership. The dealership confirmed the issue was not the sensor but internal engine damage caused by cylinder wall scoring, requiring replacement of the entire long block. Fortunately, the engine did not seize while I was driving, and no crash or injury occurred. However, before the failure was diagnosed, the only warning was repeated oil level messages that did not match the actual oil level. There were no abnormal engine noises, knocking, or noticeable loss of power. A driver could reasonably assume it was only a sensor issue and continue driving without realizing the engine had already suffered severe internal damage. If the engine failed while driving, it could create a serious safety hazard. Although GM replaced the engine under warranty, I remain concerned that a vehicle less than 16 months old with only 16,500 miles experienced such a major engine failure. I am also concerned that similar failures could occur after the factory powertrain warranty expires, leaving owners responsible for repairs that other Silverado owners have reported can cost approximately $13,000. I respectfully request that NHTSA investigate whether similar failures may also affect 2025 6.2L V8 model.

2021 Chevy Tahoe with 6.2 engine (VIN: [XXX]) has been experiencing severe oil consumption, and making odd noises during operation. All while NOTshowing ANY recalls for the issue. Although there's an active recall/investigation into the 6.2 L87 engine, which my vehicle has. I've been having Valvoline document the severe oil consumption during oil changes per manufacturer specs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

90 degree elbow on top of fuel hat on drivers side fuel tank cracked and had a bad fuel leak causing an immediate fire hazard in my garage with how combustible fuel is. There were no warning signs just walked into my garage one morning with a very strong smell of gasoline. The issue was dealt with by myself I didn’t have to take it to a mechanic to repair

STEERING NOT RETURN TO CENTER. DEALER DIAGNOSED STEERING GEAR NEEDING REPLACEMENT. DANGEROUS ON TURNING ON A CORNER AS HAVE TO PULL WHEEL BACK TO CENTER MANUALLY.

Truck suddenly refused to shift gears/stopped moving forward in HEAVY TRAFFIC, placing me and my family--and others on the roadway--in danger. Dealership inspected the vehicle on three separate occasions for the same (recurring) issue, replacing the control valve body on one visit and the entire transmission on the third. No advance warning that the issue was about to occur on any of the three instances, but check engine light came on afterward along with a message reading "reduced acceleration/drive with care".

Getting error message on and off last several weeks - "Shift into park" which does not allow the ignition to be turned off!! The only way to resolve this issue is to jiggle the gear shift or restart the car, changing gears and trying again. Sometimes it works on the second or third try! Frustrating!!! What is it doing to the shift assembly? Have called local dealer they will diagnose and repair at my cost! In the neighborhood of $250.00 for diagnostic, which will be applied to the total repair costs. No idea what that bill will be. General Motors just advises if it needs repair save my receipts in the event of recall for reimbursement. The car only has 21,600 miles!! I have seen other complaints on line and there are videos on You Tube on how to repair this issue, obviously I'm not the only one this is happening to. The gear shift boot and console have to be removed to repair. If the above actions do not work, how do you shut the ignition off??? Just let the car run until it's out of gas??? Not what I would classify as safe! General Motors should be taking steps to rectify this problem immediately but since they have not had "enough" complaints to warrant investigating further they are sitting idly by! HELP!

The valve body assembly is not letting it to shift right when driving from 50mph to 60 mph it has a clunking noise I have it replaced and is still not working correctly GM knows there is a problem with the 10 speed transmissions I have a 2023 3500 diesel with the same problem as the recalls on the 2020 to 2022 years It is doing the same thing as the 20,21 22 transmissions are having.

The diver side fuse box started a fire in the vehicle. The tracking control system light was flashing on and the vehicle lost power. Filed claim with insurance company. Insurance company issued a total loss and took possession of the vehicle.

Steering rack failure, does not return to center most of the time. Every once in a while it will. Loud clunking in steering, started right around 36k mile warranty expiration, but I didnt know what it was so did not report it right away.
