Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

1998 Subaru Legacy Owner Comments

problem #15

Legacy 4-cyl

  • Automatic transmission
  • 144,000 miles


My 98 Subaru Legacy outback 2.5 liter, 144K miles was sporadically overheating while driving on the highway through a snow/rain storm. The temperature gauge would go up, and the cabin heater would start producing cool air. I pulled over and let it cool down, filled the radiator back up with water (it had overflowed) and drove slowly home. When I took it to the mechanic, he suggested when hearing the symptoms that it was a blown head gasket, and that this Subaru engine was notorious for this. He even suggested a class action suit. After he checked it out, it was indeed a blown head gasket. After some web research on car forums, I found several other people with exactly the same problem with this particular engine.

Vehicle requires replacement of head gaskets, as part of the engine coolant system. Original service complaint was the " check engine light came on". after three days at dealer service, it was determined that the head gaskets needed replacement for the cost of $ $2,700. Because the engine has to be removed to access the gaskets. Labor will involve 3 days. The dealer has admitted that this is a design problem with the Subaru and models from 1999 will be covered. I feel the cost is excessive because of a design defect. I am will to pay but not $ $2,700. I was expecting $ 400-$500 dollars. For a $ $20 dollar seal! while not a safety defect; it certainly is a design defect!

Legacy 4WD 4-cyl

  • Automatic transmission
  • 48,528 miles
Dealer wrote: "noise from valve train...advised owner these are solid lifters and are noisy when cold, also characteristic of this engine is 'cam walk' which also will be noisy for a few minutes when cold then goes away." That wa at 48.5 K miles, now at 53000 miles, noise is much louder when cold, and still perceptable when warm. Bought car used form dealer--resale value is now much lower due to noise. Their explanation is nonsensical. Obviously dubaru does not want to deal with this issue--I wrote to Subaru usa and they refered me back to dealer.

At the beginning of February, 2003, blown engine in a 1998 Subaru Legacy 2.5 GT. Dealer stated that the problem was due to cold weather in the northeast, and that there were 4 other Subaru's with blown engines in his lot awaiting repair. I had the engine replaced with a 1999 Subaru at a trusted mechanic's (at a cost of $4000), and today the alternator on this 1999 engine died ( this had been a recall on the '98 Subaru's).

Asked dealership to look at knocking noise in engine 2 years ago, no problem identified. Asked another automobile repair facility about the noise and they claim Subaru had a history of piston slap that will eventually get worse resulting in burning oil and engine damage.

Engine noise when cold. Sounds like a lifter is sticking. It disapates when the engine warms up, however, can last up to 15 minutes or longer depending oh how cold the engine was when started. When I drove this vehicle to the dealer for its 30000 service, I thought a rod was going to shoot through the engine was that noisy. It lasted at least 10 miles of driving until the noise disapated. This auto was purchased by my mother in law (now deceased), is in her estate and has two months before warranty expires. The dealer will not repair due to alleged Subaru bulletin. Subaru of America says it is normal, will not cause a problem over the life of the engine, however claims they have not produced nor will produce a Subaru bulletin on this issue. This is not a normal operating noise and it will no doubt damage the engine over time. I would not buy this car with this sound and would not expect anyone including any Subaru dealer or Subaru of America to purchase with this engine noise, let alone try to sell one in this condition. In my mind it is a manufacturing defect and a responsibility of Subaru to fix. This is a problem Subaru needs to step up and take the responsibility for an inferior engine design. Or post a warning on every car warning potential buyers that their car may develop an engine noise due to engine design, that will effect their ability to sell the car at a later date.

I am getting a loud slapping noise from the engine on cold starts it last for about ten to fifteen minutes or untill the engine warmes up, the dealer says that it is a piston slap and that is normal. I do not agree, when I first bought the car it did not have that noise, and it is getting louder, I do not want to wait to have this problem fixed, my warrantee will expire soon
