Unfortunately I’m in the other camp. Bought a MX 100D inventory vehicle with ~900 miles on it and took delivery mid-November. I figured that since it was an inventory car any “infant mortality” issues would already have manifested and been taken care of. When I picked up the car, I noticed the satellite radio wasn’t working — had to go back to have the XM radio antenna installed, which was left out by the factory. Was at the service center for over a week waiting for parts. Got it back, ran great for 3-4 weeks, then got a warning message “Car Needs Service: Steering Assist Reduced”. Took it back to the SC, spent another week+ with them investigating the issue, but they could never determine the root cause. Got it back, and a week later I go to raise the 3rd row seats, there’s a popping sound and the left seat won’t unfold. E-mailed the service advisor (he and I know each other well now), he’s very apologetic, he orders a new seat cable and will let me know when it’s in.
The local SC (Pittsburgh/Wexford) has been great through this...they gave me a Model X loaner both times and did valet pickup and drop off, and have been very accommodating to my schedule. That doesn’t change the fact that a car with ~2000 miles on it shouldn’t have had to go in for service three times. My previous car was a Lexus RX and it was in for scheduled maintenance once a year, other than that, zero problems in 40k+ miles. Tesla’s QA is not yet where it needs to be for a luxury car company or a mass-market company. I still love driving the MX, and there’s nothing else like it, but I’d rather drive MY car than a loaner.
