“When accelerating it sounds like my vehicle is stuck in brake degrading or is making that distinguishing noise. My vehicle is in the shop for the second time to fix the same issue of park assist, side detection and front camera service. When expressing my concern for this problem of the sound the dealership said let's fix the service issues first as everything is electronic. I hope my vehicle is safe to drive.”
NHTSA complaint #11339970, filed 2020-07, 41,500 miles“During a road trip, we came to a stop and upon stepping on gas to proceed on the road and it wouldn't go. The engine revved and pulled until we were able to move. We took it to a dealership as well as private mechanic and was told it is an engine problem and running $3k or more to have it fixed. We have small children and consider this a safety hazard. Unfortunately, this is the only vehicle we have to commute.”
NHTSA complaint #11737962, filed 2026-05“For several months my check engine light has been flashing when I’m driving, especially on the highway. At times my vehicle feels sluggish. I press further own into the gas pedal and I am not getting adequate propulsion. It also feels like this when I’m going up a hill. I brought the vehicle to two independent service centers to get a diagnostic. One indicated getting misfire readings on two cylinders. The other indicated getting misfire readings in three cylinders. As you would imagine this is an extremely concerning safety risk.”
NHTSA complaint #11712159, filed 2026-01“Transmission issues on 2018 Chevy Tahoe. The vehicle stopped on the Hwy. Dealership says the transmission needs to be replaced. Is uncertain why the transmission has gone out on the vehicle since it’s only 4 years old. Error message came on my vehicle and I called the dealership. From my research it appears Chevrolet is continuing to have problems with the transmission on its Tahoes. This is unexceptionable. The consumer has to pay the price not the manufacturer. Please assist.”
NHTSA complaint #11462462, filed 2022-04“Vehicle stopped accelerating while coming up to speed from an on ramp to the interstate while traveling from Indiana to Florida. Vehicle was towed to the nearest Chevy dealership where we were told the engine had blow and would need replaced. Vehicle has been sitting on the same dealership in Florida since early July. My families lives were put at risk as we were traveling at a low rate of speed on the interstate. As well as, sitting on the side of the interstate in a remote area waiting for a tow truck and cab. The dealer has confirmed what happened via inspection. …”
