Example complaints

“I was almost involved in an accident on the highway last night, either the transmission or the real axles broke as I was driving 70 MPH. Never informed of any recall and I want answers, as it could have been a horrible accident. The car was towed to my home last night. This occurred in battle creek michigan on m66 south”
NHTSA complaint #11372526, filed 2020-11, 49,000 miles“When idling or when you cold start the car it tends to have a slight shake/tremble feel all throughout the car even passengers felt it also when accelerating slowly and you hit 15 MPH car tends to shift hard into 2nd gear”
NHTSA complaint #11246257, filed 2019-08, 38,000 miles“The vehicle accelerated on its own when it was in park, with the emergency brake engaged, and the engine was turned off. Home security camera captured the entire incident on film. Would be happy to provide the NHTSA with the footage.”
NHTSA complaint #10944214, filed 2017-01, 15,100 miles“Was simply driving my normally and out of no where there was a loud pop and driving the car all I heard was a loud grinding noise as I stepped on the gas, and the car would not shift into reverse. No lights or warnings had ever popped up into the dash. Also very strong burning and metal smell came from the car. I have taken the car to an independent repair shop and was determined the rear differential has gone bad. …”
NHTSA complaint #11489605, filed 2022-10“The recall that was done on the 2014-2015 CTS-V should have been a recall on ALL models of CTS because all of the models in the timeframe received the dsame flawed rear differential. My 2015 CTS Luxury has only 80k miles on it and the differential has chunks of metal in its oil. It is the exactaame differential as is in the CTS-V. At any time my rear end will lock up once the dofferential fully eats itself. It is an extreme saftey hazard for anyone driving any type of CTS from 2014-2015.”
