Sorry to say, but buying a Tesla is honestly a risk regarding issues with the cars. I have all 3 (s, 3 and X) and have had the following issues with the Model X;
- Trailer hitch missing on delivery and only installed months later
- Car would not leave Park, and had Parking Brake Needs Service Warning - Needed to be picked up at my home from the garage
- Fogging of the taillights - Both replaced
- Car Needs Service - Steering Assistance Reduced and Automatic Emergency Braking is Disabled - Wiring issue
- Drivers window opens extremely slow - still not rectified
- Screen yellowing issue and replaced
The car was out of service so many days in the first year I filed for protection under NJ Lemon Law.
Now having said all of the above I decided to keep the car and after the first few months of issues the car has not had any other problems so far. Even though it has been problematic for us (as has my Model S and our Model 3 is now starting with it's first issue - replacement of 12V battery), we still like these cars better than any others we have owned including Porsches, BMWs, Mercedes and Audis.
I tell most people it is a lot like owning the first generation iPhone, it is awesome most of the time, but be prepared for some issues. I still recommend Teslas to everyone that asks, but I explain that while you can have a trouble free experience, you should prepare for the Tesla Experience
