Oh I just knew someone was gonna pick that nit.
Really though, the first thing I thought after reading the full details was inadequate cooling system. Like, the engine working harder than anticipated for too long and overheating. Maybe need a new radiator and bigger pump pulley. But the chances of any car manufacturer screwing that up are nill. Probably a goofed sensor, bad thermostats or some such thing.
