i have a classic P85 built in late 2012. For the most part it's been trouble free. However, a couple of weeks ago I noticed that the driver power seat would make clicking sounds and move slightly by itself back and forth. This would happen mostly as I was leaving my neighborhood. More recently, there have been three instances where the seat has moved while I've been driving and its moved a good inch or more, enough that it pops up on screen asking if I want to save or restore the seat position. It's to the point now where it's gotten a bit dangerous and I'm going to call tesla on Monday. Just curious if anyone else has had or heard of this problem?
