My 2012 Audi A3 with 15,000 miles stranded me earlier this year when the air conditioner compressor seized which caused the accessory belt to shred which caused bits of rubber to break through wires going to a coolant temperature sensor. No alternator.
Five years ago, my F-150 with under 10,000 miles broke its accessory belt leaving it with no power steering ( a problem!) and no alternator. It had to be towed.
My 1984 Toyota Celica with 20,000 miles on it at the time blew out the oil pressure sensor along with all of the engine oil at the top of a bridge across the San Francisco Bay. Ok, I'll concede this may not be relevant these days given it was 30 years ago.
I have no idea where you come up with "very rare".
Toyota Tundra, 165k Miles, never been in the shop..Hell, only had one flat.
Of course, I have 5k on my 85D with no issues either.
