I've mostly had older cars 5-10 years old and I rarely had issues with anything in the engine. It was typically suspension, brakes, lights, the starter battery etc.

Tesla make it's difficult to fix their cars by restricting parts or bricking their cars that have been in a crash. Whilst you can get your traditional car fixed pretty much anywhere, likely to get your Tesla fixed you need the dealership more than ever.
