While driving home from work yesterday, I heard a knocking noise coming from my engine. I was just pulling into my parking lot and shut it down. Found no oil on the dipstick. Had it towed to the dealer, appears front crankshaft seal failed. Did I mention its a 2007 Aveo5 with just 11k on it. Dealer will not replace engine, they are going to repace the crankshaft, and bearings.
