I took delivery of a 2022 Model X Plaid 2 weeks ago. On my drive home, the car was shaking so badly that I turned around and drove right back to the dealer. They set up a service for the following week to balance the tires. They could not get the tires to balance and ended up replacing the 2 rear tires and it finally balanced. 6 days later, I got in the car, heard a very loud POP under the drivers side door and then a bunch of warnings and the car completely shut down. I couldn't open any doors. Car had to be towed out of my garage. After 2 days, I got a message that the Rear Drive Unit has failed. Has anyone ever faced this? Do I fight to have the car replaced? Is this an east fix?
