I'm starting to feel fairly frustrated that there still isn't a fix for the shudder the car does when accelerating quickly. Service center told me about 20% of model x cars have this issue and that they are working on a fix. Meanwhile it's been months and there still isn't a fix. Considering a spent my entire life savings and then some on a 120K car, I feel like it should be fixed within a certain amount of time or it should be replaced with a car that fits in the 80% group. (I love Tesla and this is my first negative thread. I still love my car, but I like to accelerate often and a car that shakes this much, or at all, while accelerating is not what I thought I was paying for. My shudder is bad!).
