What is wrong
On certain sport utility and passenger vehicles equipped with 4-cylinder engines, the water pump pulley center hole was improperly machined.
Risk
In some instances, the interference fit between the inner wall of the pulley center hole and the water pump drive shaft was not as tight as specified in the drawing specification. This could result in the water pump pulley dislodging from the water pump shaft, which can cause severe engine damage/seizure during vehicle usage.
Remedy
Dealers will replace the water pump. Owner notification began september 12, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact subaru at 1‑800‑782‑2783.

Cylinder head gasket failure.

Filed Jul 10, 2009 · Engine · 65,000 miles · OR

Noticed the smell of coolant when exiting the car after driving. I investigated this and found a small coolant leak coming from the back of the left cylinder head. The car is a 2003 subaru legacy gt w/ the 2.5l engine. I have owned the car since new,and had the first few services performed @ the dealer purchased,and even had a trans recall repair performed there as well.the car had around 65000 mi. On it when the leak was first noticed by me not the dealership,even though it is a known issue as told by a service rep when I questioned them on it. It took several visits to get info from them on this because they "didnt want to reveal too much info" to me,the consumer.apparently if subarus coolant additive was added before 100,000 mi. And documented @ a certified service center,subaru would cover the bill for a new cylinder head gasket, if not then it would not be covered. My question is if the additive was so important for the head gasket to survive being run then why wasnt it added at the factory or dealer before sale,and whose job was it to tell the consumers that it needed to be added.the bill is around 1200$ and from my research and observations of vehicles w the same motor (I work in the auto body repair business) this happens to most fairly early in the engines life.I think that this needs to be addressed by subaru the manufacturer,and result in a total recall and repair of this problem.they have already lost me as a customer, and actually the last time I tried contact w them theyre response was "we will remove you from our contact list".

Vehicle had coolant flush in dec 2007 (39,924 miles). Coolant leaked after this service. In jan 2008 (40,912 miles) subaru dealer put additive in coolant to seal leak and indicated manufacturer extended drivetrain warranty for this model. In dec 08 coolant leaked. Head gasket replaced 6 weeks after warranty expired (46,457 miles). There was no extension to the drivetrain warranty despite being told such by service advisor (apparently that ended in 2002). Subaru did pay for all by $500 of work. Subaru also indicated they would not guarantee the drive train belt from failing and recommended replacement at my cost.

Took vehicle in for regular maintenance and it was discovered that my head gasket is leaking. Will need to repair for $1,200-1,500.

Both head gaskets blown on a 2003 subaru legacy with about 54,000 miles and regularly maintained by the dealer car just 6 weeks out of warranty.

Filed Jul 26, 2007 · Engine · CA

Car has 78,000 miles. During reg oil change it was discovered ;hat my head gaskets are leaking oil. If not repaired will crack my heads. Cost is $2,2oo-$2,400. This seems very premature for such a serious, expensive repair to be needed. Of course warranty ran out @ 75,000 miles. Didn't extend warranty because in the past I have found that they never cover what breaks.
