6 NHTSA complaints · 2021-07 → 2026-08
“The transmission hesitates, slips, skips gears, bangs into gear, and frequently delays engagement before suddenly surging forward. Engine RPM increases without corresponding acceleration. Occupants are abruptly thrown forward and backward during normal driving”
“Within one week of delivery of this new vehicle, the transmission began slipping out of gear and the car loses power for 30-40 seconds in the middle of driving. Shift System Fault, Transmission failure, and PowerTrain Malfunction are the errors coming up on the screen”
“Navigator transmission goes into neutral when accelerating at speeds of 50+. Trans completely overhauled. Still does it. Almost had 2 accidents when changing lanes on the freeway, trying to accelerate and instead slowing down with cars behind fast approaching”
