This low-mileage vehicle experienced a catastrophic engine failure at freeway speed.

The engine died and would not restart on the side of the freeway and was towed to a service facility. After complete disassembly it was determined that the engine was not rebuild-able due to a slipped cylinder sleeve which resulted in piston, cylinder head and block damage.
