Example complaints

“The now infamous blown head gasket in phase I 2.5l engines is the focus of my complaint. Subaru of america has at least recognized the phaseii 2.5l engines in 1998 models and newer, but only because of a different metal was the problem . The overwhelming number of cases in the phase I 2.5l (1998 and prior) engine is an obvious indicator of design flaw in the actual shape of the product itself. A recall investigation is a definite must. Just another unhappy Subaru customer.”

NHTSA complaint #10066010, filed 2004-04, 99,800 miles

“Outback 1997: 108,000. Car overheated suddenly on a short trip. Replaced thermostat and flushed/filled radiator at local firestone. Two days later, car overheats. In both cases, radiator fluid ejected onto engine. Took car to dealer who identified the now very common blown head gasket . Repairs made at a cost to me of $1400! This is a defect in these automobiles that needs to be taken care of by Subaru. What does it take for this problem to be addressed? I was fortunate to not have burned my engine, others have not been. Time to take action!!”

“1997 Subaru Outback 2.5 dohc engine 1) car was suddenly leaking anti-freeze, brought it in to shop asap 2) head gasket busted, ruined the engine 3) needed to replace most of engine, including block checked other sites, this seems to be a hugely common problem with Subaru 2.5 dohc engines and they aren't doing anything about it.”

NHTSA complaint #10151537, filed 2006-03, 111,000 miles

“Noticed oil leaking from engine. Had to have front crank seal replaced. Also needed to get timing belt replaced as oil leaked into timing belt cover. Cost $368 to get fixed. Leakage began when car was just a few years old. That should not have happened as car had not been in accident or abused.”

NHTSA complaint #10154592, filed 2006-04, 50,000 miles

“Spark plug popped out of head while driving, engine died. Spark plug unable to be reinserted resulting in a head replacement. Very expensive! Only 135000 miles regular mechanic said that he has seen 4 of these cases in this model in the last 3 months. No acknowledgement form dealer about mechanical defect.”
