Had my first significantly unsatisfactory SC experience last week. The car was scheduled to have the front DU replaced, the side window alignment fixed and one of the arm rest screws (which I gave them) put back. The seatbelt inspection was scheduled and I asked them to check the tire pressures (which the car reported as 42 all around). They had the car for 3 days. While I had the loaner (a new 90D) I called and asked them to check the rear camera (the 90D camera looked like HD) to see if it was out of focus/working properly. They called on day 2 to say that they were checking the oil level in the DU, it was low, and the noise was now much lower. On day 3 when I picked up the car I found that 1. the front DU noise was now louder than before, 2. the armrest was not fixed, 3. the tires were now at 41 psi, 4. the windows were not aligned properly and 5. the battery was down to 106 miles (I dropped it off at 192). I am not sure what they actually did to the car, but it is NOT fixed. I am really disappointed and not sure where to escalate this to. This visit to the SC was, in my opinion, a total FAIL on Teslas part.
Just under 10K miles on car.
