Perhaps it has something to do with the way the car is being driven. I am not by any stretch implying that the owners with multiple failures are mistreating their cars but it does seem strange that some cars have had multiple failures and some cars have had none.
Perhaps it has something to do with stop and go traffic, rapid acceleration, sustained high speed cruising, etc.?
