Engine and engine cooling

29 reports1 crash1 fire
“THIS IS THE SECOND WELL MAINTAINED SUBARU LEGACY THAT THE ENGINE HAS BLOWN IN UNDER 150,000 MILES. FIRST A 1999 AND NOW A 2005. RESEARCH ONLINE SHOWS THAT THIS IS AN ONGOING PROBLEM AND HAS ALSO BEEN CONFIRMED BY INDEPENDENT MECHANICS. PLEASE ADVISE WHAT RECOURSE I CAN TAKE LEGALLY AS SUBARU HAS NOT OFFERED TO HAVE THE CAR TOWED FOR AN INSPECTION. THE LAST TIME THEY OFFERED A $500 CREDIT TOWARDS A PROPOSED REPAIR THAT WAS ESTIMATED AT THOUSANDS OF DOLLARS OVER THE CLOSEST INDEPENDENT. I WOULD LIKE TO FIND OUT IF THE GOVERNMENT HAS HAD ANY SUCCESS IN GETTING SUBARU TO ADMIT THE PROBLEM AND DO SOMETHING MEANINGFUL TO ADDRESS IT, OR IF THERE IS A CLASS ACTION SUIT I CAN JOIN TO GET SOME SATISFACTION. THANKS YOU. *KB”

“THE CD PLAYER TURNS ON BY ITSELF WHEN RADIO IS ON. NOTHING SPECIFICALLY MAKES IT HAPPEN LIKE HITTING A BUMP OR ANYTHING IT DOES IT WHILE CAR IS STILL. CAR WAS TAKIN ON TO BE LOOKED AT BUT THEY SAID NOTHING COULD BE DONE. ALSO, GEAR SHIFT DOESN'T ALWAYS LOCK IN PLACE. WHICH MAKES THE CAR NOT ABLE TO START AND/OR MOVE IF ON A SLIGHTLY HILL.”

Service brakes

22 reports
“While driving to work, my brake pedal went to the floor and I lost 90% of braking power. After managing to get the car back home, and topping up brake fluid, I noticed a puddle of it right in front of the passenger rear wheel. After doing research, found that this was a problem for this car, covered under recall WQK-47. Having bought this car used a few months ago, I checked and apparently this recall had been performed, but was obviously not successful in preventing the failure of my brakes. After researching the recall, found that there were 2 remedies depending on the inspection performed by the dealer when the car was brought in for the original recall work. According to the service records, the application of a protective rustproofing wax material was performed, which was supposed to prevent the deterioration of the brake lines. The other remedy for the recall was to replace the brake lines, which was not done on my vehicle. After this issue happened, I brought my vehicle to my Subaru dealer, and contacted Subaru of America to open a case. After a week and minimal communication or information from Subaru of America, I received a call stating they would not…”
