Jiffy Lube back in WV had some issues as well. Two of which happened to associates of mine.
1. Guy takes his ~2000 Blazer to JL for an oil change. Once finished, he drove off, didn't get far, and the engine seized. Someone forgot to put oil back in.

2. Woman takes her ~1995 Windstar in for a fuel filter change. Once finished, she drove it home and parked it in the garage. Some time passes, and the van explodes. They forgot to fully tighten some fuel lines. Fumes/gas reached the gas hot water heater in the garage (floor level, since house was built before new code).

Crazy.
