“My 2005 Subaru Forester, has been serviced regularly at dwyer and sons Subaru dealership in commerce, michigan. During all scheduled maintenance, I've always discussed with their service department that I have a potential problem with the engine. The engine would downshift very hard or seemed like something was banging. Or running very rough. The RPM would also seem to run lower than normal. Every time I made them aware of the problem, while the vehicle was under warranty, the dealership was never able to diagnose the problem. …”

“We purchased a 2005 Subaru Forester from a Subaru dealer in august 2008 at 60,000 miles. Since august 2008, we had four episodes of engine stalling with check engine lamp coming on. We had to have our car towed four times to the Subaru dealership. The first and third towing resulted in replacement of ignition coil. The second towing resulted in no repair since the problem could not be diagnosed. Before the fourth towing, we just got on a freeway and started to accelerate when engine lost power so we quickly got off the freeway and managed to park Forester in an empty parking lot. …”

“My car hesitates, sputters and bucks when the weather is wet. At first this only happened when the engine was cold. While this problem is sporadic, it has occurred many times since we bought the car. It now happens when the engine is warm and the car is being driven on the highway, causing a dangerous situation. The dealer at first told us many times to ignore the problem because it would go away when the car warmed up; they failed to find the defect at first. Now, after finding the cylinder misfire problem they now claim the defect isn't covered by warranty. …”

“Our company uses ten Subaru foresters as fleet vehicles for utility field work. Of the ten vehicles five are 2005 foresters and out of the five, three different vehicles had to have the catalytic converter replaced at the company's expense. Another vehicle was a 2006 model and had its catalytic converter changed at no cost due to warranty. The four vehicle VIN numbers and miles at which they had to be replaced are: mileage 94,742, mileage at 82,491, mileage 90,732 and mileage 64,059(2006 warranty). We find this failure rate to be abnormally high and question the parts failure rate.”

“After taking my Subaru forrester in for a recall for a valve in the gas tank. I was told the headgasket leaked and needed replacement! During the repair of the headgasket I received a call from the dealership informing me I also had a cracked cylinder head. This is my 4th Subaru I never experienced anything like this before. When I researched the issue I noticed that Subaru had a ton of headgasket recalls starting in 1997. There seems to be a general lack of quality in regards to this.”
