Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When accelerating, the car feels stuck to gear up. After 2 seconds of loud revving, it would switch and have a prominent jerk motion that it finally switched gears. There have been times the car wouldn't go past 30 mph, stuck at the gear making a loud noise. This is dangerous! There's absolutely no way I can get on the freeway never getting past 30ish mph. I checked recalls for this vehicle and there isn't any. No warning lights in the dash.”
