During my last visit to the closest SC (1.5+ hours away), there were no loaners and they gave me a week's worth of Uber credits ($100/day). My car ended up sitting outside for 9 days until they were able to work on it. They didn't enable service mode until then and I could see the car's exact location in the overflow parking lot and that the interior temperature was exceeding 109 degrees during the day. In fact, I had to ask them to plug my car in as the battery got down to 10%. The repair ended up taking less than 2 hours. I had to pay out of pocket for the return Uber ride up there with the promise of reimbursement. It's been three months and my emails go unanswered.
Unfortunately, this is a common occurrence every time I drop my car off there. The car usually cannot be looked at for at least 2-3 days and they assume that you are dropping the vehicle off for the appointment and not waiting. Why not just schedule an appointment when there are techs able to work on the vehicle? It seems to be a time/resource-management issue. I understand that they are overwhelmed with the influx of new cars with issues, but they should not continue to schedule appointments if they already have a three-day (or more) queue of cars. I would prefer that they reschedule my appointment 3-4 days in advance if that means I can have my car back in one day at a future appointment. I have never been able to wait for my vehicle (which has been serviced at least 9 times in the last year) and they have always taken three or more days for any repair at the SC. I have also noticed that the waiting area, which used to have a TV (with live content), snacks, waters, coffee, and soft drinks, is now barren with a scrolling Tesla ad on the television. If I didn't love my car so much....
On a positive note, the Tesla mobile techs (formerly known as the Rangers) in Colorado are pretty fantastic, knowledgeable and accommodating. Our local tech, Jack, has had my whole front fascia removed in my work's parking lot to replace headlights, he has reprogrammed my key fobs, manually pushed software, replaced small body panels, etc. Maybe if they had a couple more of these guys, they could alleviate even more of the congestion on the SC for the more common/easier fixes.
