We recently went for a hike which involved parking in a lot with no shade. Sun was reasonably strong but ambient temp was in the 70-80s. When we came back from the ~2 hour hike and got in the car, the cluster gauge was on but the MCU was black and hot to the touch. No matter what reset I tried, the MCU would not come on and the car would not start. After about 10 minutes, the car decided it was OK to start and drive, but MCU was dead with all auxiliary stuff being dead also (meaning no AC, no ambient temp measurement, no sunroof control, no music, etc). About 10 more minutes and the MCU came on, but I had to reset it twice to make it work. Questions: - Isn't this exactly what the cabin overheat protection should solve? - Does this happen to others? - Is this a warranty problem or kind of like an overheated iPhone, there is not much one can do but cover the unit from the sun?
