This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Vehicle reduced power and displayed many errors on the dashboard, including reduced function of forward collision avoidance, reduced acceleration, ESC SES TC. A vibration/rumble was observed (unsure if it was steering assist or propulsion surging), as well as increased engine speed without vehicle acceleration and no engine speed increase while pressing the accelerator. Turns seemed to make the symptoms worse and cycling power on the truck would temporarily clear the faults. Root cause was determined to be TSB 21-NA-149 Cause 3 and diagnosis and repairs took more than a week.
Brake control module failed and is available for inspection. It is still at the dealership as the part needed for repair is backordered. I had trouble braking and steering vehicle putting myself and others at risk but fortunately was in a parking lot at low speed. Problem has been inspected confirmed by dealership only. Warning lamps/messages first appeared at time of incident, none prior.
Hi, My truck was ordered May 2021. Came in January 22, 2022 as a 22 model year. Its a 4 wheel drive with the Duramax diesel option. Ran great until around 6000 miles where I started to experience a miriad of electril issues including a completely malfunction anti collision system, transmission problems, several electrical problems and worst of all "Reduced Acceleration" otherwise known as "Limp Mode" in diesels. The check engine light came on also and my MPG dropped from 18-28 mpg to 12 mpg.The dealer told me that they were backed up with diesel trucks and to hold off. On July 8, 2022, the truck went into limp mode while trying to accerae onto a major highway. I had the horn blown at me and almost got rearended trying to get on the highway. I had nowhere to go and it took me about two minutes to get up to 60mph. I got off the highway and limped to the dealership. The truck spent 122 days in the dealership and despite me trying to lemon the truck, they said it was fixed after around 110 days. I was forced to pick it up. It broke down in the parking lot before I could drive out of the dealership. I am now taking action agaisnt GM. This is not a Chevrolet issue with the dealership but GM. Their factory reps rebuilt some wiring harness in my truck. Something to do with the transmission module. Again, I dont have a problem with the dealer. The truck seems to be running fine but I have notice some strange behavior with the forward anti collision system and the auto brake. It doesn-??t work all the time. I can, t tell when it will work and if it works at all. I will be bringing the truck back to the dealership. Now, this is a major problem because im not the only one complaining about the anti collision system. I know someone who says his same year diesel Chevy pickup has an issue with the camera not working in the front and he doesn-??t trust the anti collision system as well and he is in the business. This is a major problem GM is hiding from the public.
Remote started my Tahoe, got in and the dash said -??brake system failure-??. I put it in reverse and sure enough complete loss/failure of brakes. Let the car shut down and cycle, tried to move it again, same thing happened. Depressed my foot on the brake to the floor and no response from the brakes or braking system.
The contact owns a 2022 Chevrolet Tahoe. The contact stated while starting the vehicle at a parking lot, the ABS, the Electronic Stability Control (ESC), braking system failure, traction control, and the brake motor warning lights were illuminated. The contact stated she began to drive at a slow speed and noticed that while depressing the brake pedal, the brake pedal was firm and failed to stop the vehicle. The contact came to a stop and parked the vehicle. The vehicle was not drivable. The contact towed the vehicle to the local dealer however, the warning lights were off. The mechanic was unable to duplicate the failure. The manufacturer had been informed of the failure. The failure mileage was approximately 4,000.
