> Worn half shafts caused shudder under acceleration, replaced at ~20k miles I owned a 2016 Model X, and I got the dreaded half-shaft shudder after only 5k miles. When I took it in to the SC for evaluation, the tech driving the car blurted, "Oh yeah, there it is! This happens with all the Model Xs" when moderately accelerating uphill and the car shuddered quite a bit. Fast-forward 20 minutes, I'm sitting at the desk with the SC rep, and they say, "Yes there was a shudder, but that's normal." That was the 11th -- and final -- issue I had with that car. I traded it in for a Jaguar I-PACE shortly after and never looked back.
