NHTSA Complaint #11507971 — 2013 TOYOTA 4RUNNER

1) The failed component is the door locks. Or more precisely, the motor for the electrical operation of the door locks. When failed, the door remains locked even when pulling on the interior handle to open the door or when trying to unlock the door using the interior latch. You are essentially locked inside your car. I believe the door should always unlock when the handle is pulled, and the interior lock lever should always unlock the door as well. Both of these function "normally" when the actuator is not failed. The failure first appeared in late 2018/early 2019. I noticed that when I locked the vehicle using the key fob, I was not hearing the audible "beep." And when the car was shifted out of PARK, I was not hearing all the doors lock. I then realized the drivers front door was not locking. I lived with this for a while, long enough for the drivers side rear door to fail, and then the right rear door failed as well. The front right and rear door have never failed. I purchased a Toyota lock assembly for the drivers side front and it functioned perfectly after replacement until this past week. It appears to have failed again. And I was essentially trapped in the drivers seat. I had to give it and electrical command to unlock while pushing on the manual lever in order for the door to unlock. Pulling the open handle did not open the door, and pushing on the manual lock lever did not open the lock. The failed component appears to be a small motor in the lock assy. I replaced this motor in the left and right rear door lock assembly's and that corrected the problem. I am going to replace the motor in the lock assy I removed in 2019 and reinstall it in hopes of correcting the problem. I can send you the Toyota lock assy I will remove, and one of the motors I removed from one of the rear door lock assembly's. 2)The failed door locks trap occupants inside the vehicle. 3)Did not visit a dealer or repair center. 4)No inspections have been performed. 5)No
