We have classified the 1 complaints from 2010 Subaru Impreza about ENGINE AND ENGINE COOLING into the following categories.
First failure was my clutch due to the pressure plate being installed incorrectly from the factory and was warranted. second failure was an air fuel sensor which also was covered under warranty. third failure was my 4th cylinder cracked piston. the dealership which has been the same that i have gone to for all my service and warranty refused to warranty the pistons because of an aftermarket exhaust which was installed for the first two warranty failures mentioned above. i was forced to pay out of pocket to have the repairs done!
Before the failure white smoke came out the tailpipe and the engine was hesitating. piston #4 had a failed ringland causing the engine to fail. to correct the failure the engine had to be taken apart at the dealer and have new parts installed. the car was out of my possession for two weeks. the car had only ~8000 miles on it and it appears to be a very common problem on 2008-2010+ subaru impreza sti's. *tr
