So with around 7600 miles on the clock on my P3D+, the rear drive unit has failed. Worth noting that I took delivery during 3rd quarter in 2018 (THE quarter when Tesla was pushing HARD to crank these out), AND I have self-installed an aftermarket sub/amp system. For what its worth, I've installed audio systems in my own cars for the last 8 cars and while that doesn't make me a pro, I also like to think I did it right/clean. The short: rear drive unit failed, they're replacing the entire unit, i feel l Full story: My wife charged up to 100% on this trip as she was going far. When the battery was at around 56%, she felt what she described as the rear "dragging". During this time a message pops up saying "Rear drive unit problem, car coming to a complete stop" or something along those lines (i wasn't there). The car eventually comes to a complete stop in the middle of the road at 9pm. The message to try exiting and re-entering comes up (and doesn't work). Car won't shift into D or R. Wife calls Tesla support to explain the situation, and was told to call 911 (really?). I call Tesla myself to explain the situation, and they say they won't have a tow truck for the next 4-5 hours. While I'm trying to work out a tow with Tesla, I get a call from the wife because the police showed up and want to push the car off the road. I hang up with Tesla and walk through the steps with the wife to get it into transport mode. The car had trouble staying in transport mode, moving about a foot before the car shuts down (black screen, rear motors lock up). It took several reboots and putting into transport mode before they're able to get the car off the road. I couldn't have my wife sitting 150+ miles away by herself in the night for 4-5 hours, so I decided we'd use our our tow services with AAA to get the car to her friends house 40 miles away. The next morning, Tesla towed the car to the nearest SC. To which I got a loaner and was explained that the rear drive unit failed, it's rare, it's a big job, they'll need the car for a while as they want to monitor it after replacement, and that they'd let me know when its ready. This happened thursday night, today is Tuesday. Still waiting. They did not mention anything about the aftermarket sub or whether or not it had anything to do with the failure. Does this change my love for the car? NO! I love it. BUt it does leave me wanting more out of Tesla's support. I don't think tesla's response of calling 911 was appropriate. I also feel like the claims about having redundancy with having a dual motor car didn't work out here. And the fact that it kept coming OUT of transport mode can be frustrating/dangerous. Anyways, just wanted to share as my googling of this issue has me concluded that while it has happened, it's not a super common thing.
