Example complaints

“Chevrolet has a recall on some vehicles for a bad transmission valve body, but my vehicle isn’t a part of the recall and I’m having the exact same issues. Currently my only vehicle that I have to transport my 7 month old is a complete safety risk. My check engine light is on and the code its throwing is to replace transmission valve body assembly. My Tahoe is shifting very harshly when driving normally, it feels like it slams into gears causing the whole car to jerk. …”
NHTSA complaint #11745868, filed 2026-06“I was at a red light and when I tried to take off the RPMs reeved up and my car would not move so I turned it off, opened and shut my door, restarted my car and it would move 100yds if that, then the RPMs shot up again (acted like it couldn’t shift out of first gear). Car has 101,647 miles, was serviced on time, no issues before and no warning lights on the dash came on before or after the issue happened. Car has not been repaired yet and still no lights on the dash.”
NHTSA complaint #11634899, filed 2025-01“My transmission failed, yes it is available for inspection. The failure occurred without warning. I was driving my truck on the highway, suddenly it began to hesitate and making a loud winding out noise. The truck was hesitate on going forward. Yes, I had the vehicle towed to Banks Chevy, I was told the torque converter blew metal shavings into the transmission and it was a common problem with these vehicles. No warning at all, I just had my oil changed at the dealership, it was running great, out of nowhere this happened.”
NHTSA complaint #11747899, filed 2026-07“While driving, the vehicle's RPM's accelerated quickly and then the vehicle stopped in the middle of the road and would not move. I could not even get it to the side of the road to be out of traffic. All regular maintenance has been performed. The mileage is almost 100,000, but not there yet. This could have been a very dangerous situation as I was heading to an interstate highway. No warning lamps ever lit up and no strange sounds or vibrations ever came from the vehicle. This happened suddenly. No warning whatsoever. The vehicle is being repaired today. …”
NHTSA complaint #11626645, filed 2024-11“I was starting to accelerate to a higher level of speed onto the highway; 55 mph going up a hill. I was unable to accelerate much as I pushed on the gas, however the RPM's would get higher. while I was at 45 mpg the RPM's were at 3.5. All of sudden my service engine light came on. I knew something was wrong. Turned around took my car back home very slowly, had my husband come look at my car, who has mechanical experience. Transmission fluid is dark and gritty; when its suppose to be a red in color and smooth. I am now needing to replace a transmission in a vehicle that is 5 years old. …”
