NHTSA Complaint #11687825 — 2021 TOYOTA RAV4

My driver seat suddenly stopped working correctly when trying to move the seat forward or backward. It would make this lagging noise and feel like it was jumping. We had to keep the seat in the position that would be safe for me to sit in and operate the car effectively, but needed to get it fixed because my partner could not sit in the same position and operate the vehicle safely from that position. Took my car to the dealership and they found the track on the right side of the seat was inoperable and the whole bottom frame needed to be replaced. The tech could not produce a reason why this happened, simply saying it gave out. No messages or other symptoms prior to the failure. It happened quickly, one day it was working fine and the next it failed.
