The power passenger seat makes a grinding noise that sounds like it's the motor. It happens about 50% of the time. The driver seat has been fine and I've recorded video showing the difference. The dealer took it in and agreed something was wrong. They ordered new tracks for the seat. The problem appeared resolved for a few days but then reappeared.

Every time we bring it into the dealer though to get them to fix it again, the noise disappears. I believe that it's not the tracks but the motor. We will bring it in again when another grocery list of problems pile up with the car...we usually have about 3 things broken under warranty at any given time.
