“Car when idle shuts off in middle of traffic locking break an steering wheel can cause accident happened to me in middle of traffic thank god I was close to emergency exit car shutoff not allowing to brake had to press emergency brake.”
NHTSA complaint #11323974, filed 2020-05, 140,074 miles“There is a recurring problem that the seat will automatically go into the easy exit position. This is not a problem for me as I drive with the seat as far back as possible, but this is a huge safety concern for my wife. Why hasn't this been recalled yet? This seems to be a common problem in this make and model. God forbid the electrical problem worsens and causes a fire.”
NHTSA complaint #10549236, filed 2013-10, 29,000 miles“While driving vehicle my seat will decide to move on its own and pull me away from the pedals also the dome light comes on and it does this all the time very dangerous now my car will not start at all due to the ignition switch I believe.”
NHTSA complaint #10928199, filed 2016-11, 135,000 miles“While driving the vehicle, the seat suddenly went all the way back and the interior lights came on. This has happened several times since then, we finally figured out it was the ignition, with the car acting like the key just got put in the ignition or just pulled out, and the seat moving all the way back for easier ingress/egress and the courtesy lights coming on. Since I am only 5 foot 4 inches, when the seat moves back I can no longer reach the petals, a very dangerous situation while driving.”
NHTSA complaint #10967171, filed 2017-03, 90,000 miles“While driving, I moved my foot from the accelerator to the brakes, and my knee brushed along the key fob dangling from the ignition switch. The seats then automatically retracted to the rear position. This has now happened four times, and seems to be extremely dangerous--particularly because it happens when moving my foot to the brake. While I reacted quickly enough in these normal incidents, if I was braking to avoid an accident, I doubt I'd be so lucky.”
