There are 7 owner-reported powertrain & transmission complaints for the 2017 Tesla Model Xin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
This year Tesla has a known "acceleration shutter" due to the front CV joints' angle being too sharp causing premature wear. I have been dealing with this issue since the vehicle was new. Tesla has replaced my CV joints 5-7 times and during the repairs they have left bolts out of the vehicle, left bolts loose and damaged the front drive unit so much by bad repair jobs they have had to replace the front drive unit twice. In the most recent episode, the motor mount has cracked and was making a loud banging noise under acceleration and declaration. Most concerning is the fact I found some brake lines not in their keepers and they were rubbing on this mount. (I have photos). I have had my vehicle at 3 different Tesla service centers and at least two are inadequate. My concern, especially with the loose and missing bolts, is the sense of bad workmanship which could lead to a real problem in the future. I have, myself, fixed the brake line issue and tightened the motor mount bolt and the car is fine but don't know what else is not done properly, so I will be asking a service center (over , 100 miles away) to please check to make sure there isn't anything else loose due to the front drive unit being replaced. I also have another bad half shaft which was replaced about 10,000 miles ago back in October of 23'. I have pictures of all this nonsense if you are interested. But again, my concern is what if they leave something important loose that can kill someone. I've had many episodes of shoddy workmanship from two different service centers. Hundreds of miles apart. It appears to be either a training or culture issue. The jury is still out on the 3d service center, but it's not looking good at the moment.
Car has been sent to the shop twice for the axles / half shafts and also two times for the front drive unit

I'M NOT FROM THE US, BUT WANT TO LET YOU KNOW THAT THERE ARE ALSO SAFETY PROBLEMS WITH MODEL X CARS IN EUROPE. MY CAR, A TESLA X FROM APRIL 2017 WITH 93.682 KILOMETERS DRIVEN BROKE DOWN WITH A BROKEN SUSPENSION PART. THE WHEEL WAS MOVING FOR- AND BACKWARDS COMPARED TO THE VEHICLE. TESLA CALS THE PART FORE LINK ASSY LH (1041570-00-B). WHEN PARKING THE CAR IN REVERSE, THE FRONT A THE CAR CAME UP FOR 5 CENTIMETERS. IT HAPPENED ALSO DRIVING SLOWLY FORWARD. THE BIG RING ON THE END OF THIS PART (THE SITE THAT IS CONNECTED CLOSE TO THE WHEEL) WAS COMPLETELY TORN OPEN. TESLA ALSO HAD TO REPLACE THE LEFT AND RIGHT FR SUSP AFT LINK ASSY BECAUSE OF "WEAR AND TEAR". UPPER CONTROL ARM WERE ALREADY REPLACED IN JUNE 2020. REAR MOTOR REPLACED JANUARI 2018, ELECTRONICS FOR OPENING FRONT DOORS REPLACED IN MARCH 2020, NEW POWER STEERING APRIL 2020. I LIKE YOU TO INVITE THE ALSO LOOK AT SUSPENSION SAFETY ISSUES IN EUROPE WITH THE MODEL X AND S. THESE ISSUES HAVE NOTHING TO DO WITH ROAD CONDITIONS, WE HAVE VERY NICE SMOOTH ROADS HERE IN THE NETHERLANDS. I MADE A VIDEO OF THE MOVEMENT OF THE FRONT LEFT WHEEL.
