Dunno why, but it certainly happens here. Could be a climate thing with the rubber seals and hoses and stuff..... but it happens.
The owner of that car is a friend of a friend, I think. If I'm destined to fine out more, I'll share... but it certainly looks consistent with the other instances. Basically the car just spontaneously combusts, with no warning whatsoever. This happened at KUL- Kuala Lumpur International Airport.... right at the passenger drop off, so he obviously drove all the way there, got out of the car, was in the middle of loading/unloading the car (tailgate is open) and next thing he knows.... *kablooie*.
