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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Subaru Legacy Owner Comments

problem #4

Dec 132008


  • 46,457 miles


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.

2003 Subaru Legacy is leaking anti-freeze. Coolant leaked due to a defective engine design. The aluminum block and head did not contract together causing the problem.
