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.

1999 Subaru Legacy Owner Comments

problem #2

May 112011

Legacy SUS 4 cyl

  • Automatic transmission
  • 179,000 miles


This engine has had oil leaks before it went out of warranty. It would leave puddles of oil in the garage floor. Put a tray there to catch the oil. Enough to pour it back in every week.

I Took it in to repaired for oil leaks at mileage 150,000, mechanic said, "Forget it. You need a new engine."

Not too long after that it began to overheat. To a Mechanic who said, "Forget it. You need a new engine." Diagnosed with probably 2 blown or leaking head gaskets.

UGH. Can't afford a new engine.

It's been sitting for a LONG time in my driveway. I start it and drive it for about 15 minutes and return it to its resting place. I would like to get it fixed for my son to drive. But not about to spend $2,000+ on it.

Enough of the whining.

problem #1

Feb 012011

Legacy GT 2.5L

  • Automatic transmission
  • 98,000 miles

I am the third owner and bought it at 92k miles in Feb. '11. Overheating @ 102k miles on the 2.5L GT which is around the same time others online started having the same problem. I have tried changing to a new OEM thermostat and doing a radiator flush at Jeffy Lube with no luck. I've also tried those liquids you pour into the radiator overflow with no luck. After doing a research I found that SIX STAR head gaskets were the best replacement over the Subaru OEM gaskets. I order it from ($118). It is best to have the cylinder heads machined, water pump replaced & all the timing belt pulley & timing belt replaced when doing the head gasket. After that was done I didn't have no more over heating problems. DON'T BUY CHEAP head gaskets because you'll end up replacing it in about 20k miles. That's another $1500-2,000 job you don't want to pay for again. I highly recommend buying SIX STAR head gaskets!!! I'm still running my '99 Legacy GT and its at 118k miles as of April '12.
