NHTSA Complaint #11430693 — 2020 TOYOTA HIGHLANDER

The driver seat started making a motorized noise 2-3 days after I purchased the vehicle. Over the few months from my oil change the noise got louder and louder as we moved the seat back and forth. When I took my vehicle in for its first oil change I addressed it to the dealership as the seat was now no longer able to move forward or backwards. During their inspection they stated there was a lego which was not possible as I had at the time a 1 & 2 year old who would choke on a lego so there is no way I would allow them to play with legos that small, mega blocks okay because those are huge but legos are too small. Anywho the seat was functionable after the inspection which lasted about a month and then went out again. I then brought it up again at the next oil change which they Checked it out and it worked a bit then went out again. The last time I took my vehicle in for its last oil change I addressed it, they took it apart and left it that way as it is now but were unable to locate the reason why it was defaulted. I however found that a piece was missing from one side of the track under the seat but they couldn't see that it was the reason for the malfunction. I have tried multiple times at least 5 times and speaking with the 2 service managers but to no avail this driver seat still can not be adjusted which means no one can drive my vehicle aside from myself not even in case of an emergency. There are no warning lights or alerts that come up.
