I have a Model X long range that is a little over 1 year old with about 12,000 miles on the odometer. It developed the "dreaded" suspension shudder under acceleration. Tesla replaced both front axles and this seemed to help, however after about 600 miles of driving following the replacement I was just driving around town at low speed one evening and as I slowed down for a stop light there was a loud "thump" on the front right side followed by a very loud screeching/grinding noise. I pulled to the side of the road and the car shut down. I contacted Roadside Assistance. They had me reset the car and try to move it; however, it would barely budge and there was a loud grinding noise coming from the front when I stepped on the accelerator. Tesla sent a tow truck and towed the car to the Marietta, GA Service Center (about 120 miles from where I live). They serviced the car the next day and told me that one of the newly installed front axles had broken. Also, after they replaced that axle they took the car out for a test drive and the other newly installed front axle broke. So, they replaced that one too. When I picked-up the car the next day, I was told that when the axles were originally replaced they hadn't been seated properly and that now the problem should be solved. So, I returned home and the car seemed to be running fine with no vibration (shudder) when accelerating. Today I took the car out for a short drive and as I accelerated away from a stoplight, I heard the same loud "thump" on the front right side followed by the same grinding noise. So I assume an axle has broken again. This time the car continued to be drivable and I was able to make it home. I've set-up another service appointment; however, since this problem has happened twice now in close succession I'm starting to wonder if there is some basic flaw in the drive train. Even if they repair it again, I won't feel I can trust the car for trips (i.e., I worry I'll get stranded somewhere far from home and possibly far from Tesla Service). I'm wondering if anyone else has had this problem and if they know what it took to fix it.
