“The alarm will sound randomly while driving or parked. We are not sure what is going on. It happens dozens of times a day and alarms my teenage driver. The button is not pushed, nothing is touching the car. Just random. We want this fixed because it is a safety concern, especially when she is driving and the alarm goes off for no reason.”
NHTSA complaint #11170389, filed 2019-01, 100,000 miles“My driver side door lock button does not work. As the driver, I am unable to unlock or lock doors using this button.
