NHTSA Complaint #11679174 — 2022 GMC SIERRA 1500

The vehicle’s shift control module in the transmission is malfunctioning. The vehicle is shifting hard and having trouble finding the gears. The safety issue is that this is a known GMC transmission malfunction with the risk that the rear wheels can lock up when downshifting in the higher gears. Sudden rear wheels lock up proses a risk to cause an accident on the roadway potentially harming the driver and passengers in the defective vehicle as well as risking other drivers on the road. No warnings were given before the malfunction. The vehicle has been regularly serviced on time and taken care of. The malfunction began and within one week the vehicle progressed to shifting so hard I didn’t feel comfortable driving it especially with my child in tow.
