NHTSA complaint #11607419, filed 2024-08“I have a 2018 GMC TERRAIN which I bought brand new from General Motors.

I have taken it to the dealership on three different occasions for repair and I still have this issue. General Motors engineers were involved in every step of the repairs. They just do not know what is going on with the car or fix it and they are too stubborn. The dealership told me today that they cannot do anything else to the car. …”
