During a service visit, a replacement electronic control unit (ECU) may have been installed with incorrect programming, which can cause the automatic door locking (ADL) function to not lock the doors as intended.

Risk. Doors that do not lock as intended while the vehicle is in motion may open during a crash, increasing the risk of injury.

While parallel parking in a parking structure; my car accelerated full throttle backing up hitting the back wall ; then I tried going forward to straighten the car up, it accelerated full throttle forward hitting the front wall. I had an doctors appt. there and decided to still straighten car and I said if it goes full throttle again I would immediately put the car in neutral and turn the car off, which I did. Each time the car went full throttle I hit the brake pedal as hard as I can push. Leaving the car I tried locking the car with my key fob, it wouldn't lock or turn off the headlights, it caused the horn to keep beeping for no reason.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
