Took delivery of my X90D 5 days ago. Had the seats xpelled the following day then CQuartz applied the next business day. Have had the car to commute to work for the first time today and am noticing a wobble when accelerating or decelerating. Can manually wobble it when using my hands if I am not sitting in it. The passenger seat doesn't wobble. Any one else have this issue? Read about the same problem in the model S forum. Can anything be done? I've also noticed my trailer lights don't turn on when plugged into my trailer electronic receiver but I will try another trailer to make sure it isn't the trailer itself that is the problem.
