Mobile service came and looked at my car Monday and said it needs new upper ball joints (at 47k miles) and a new VC right control board. (this will be it's third one). The last one was replaced two weeks ago in St. Louis during a road trip. The car is operable, but the ball joints are getting exponentially worse each time it's driven. I'm not sure I would trust it to on a 300 mile road trip. I asked what to do and Mobile said they would escalate my case but it would need to go to the nearest service center which is about five hours away. That was Monday and so far, I haven't heard anything. I can set up an appointment through the app, but there's no way on knowing if they will have the parts in stock when I arrive, and I can't afford to stay in a hotel until they do arrive. I also can't drive two cars and leave the Tesla until it's repaired. As you can see from the mileage, this is our daily driver and I need it back as soon as possible. I need to know the parts will be available when I arrive, so service can be done that day. Iv'e tried calling their local number and just get stuck in an endless loop that says go online or through the app. Even when I tried the option for new sales, it wasn't possible to speak to a real person. How are you going to tell people how great Tesla is, if you don't answer the phone!
