Just bang out of no where! Apparently, not as uncommon as the fanboys would like you to believe. There was a new Model X being towed in on dollies at the same time as my car. Everyone from the tow truck driver to the SC advisors knew immediately what was wrong before even looking at the car because they have seen it so many times. I drive my Model S very delicately because I planned to keep it as a long term daily driver. Now I am looking for an early exit!! I haven't had a car leave me stranded on the side of the road since I was in college driving POS hand me downs, which was about 30 years ago. They didn't cost me $100K. And I have owned literally every "unreliable" American and European brand you can name, including their super unreliable exotic brands. The salt in the would was Tesla Roadside trying to tell me I had to pay for the tow when they screwed up ordering the tow truck!
