Complaint Summary
POWER TRAIN
Owner Narrative
The transmission of the 2021 Suburban failed. While operating the vehicle down a state highway, out of nowhere the power was reduced significantly while in traffic. It would not go over 30 MPH after forcing itself to 30 MPH while driving down the busy highway. After struggling to find a safe place to park, the vehicle would not, and still will not, go into reverse. There were no warning lights of any sort prior to this incident. Now there are several warning lights. The vehicle has been towed and taken to a repair shop with current unknown diagnostics as we are waiting our turn for the vehicle to be diagnosed. This vehicle has a transmission that is currently under Class Action for GM knowingly selling defective transmissions.
