“The Subaru of america dealership would not pay for a ecu replacement at the Subaru dealership I brought the 2007 Impreza outback sport to. The bill is $1,100.00 and I am really disappointed in this dealership. They said the mileage is too high to be covered by any warranty. The mileage to date is at 113,000 miles. I received a letter to get the fuel tank one way fuel valve replaced. I did not get that replaced and the Subaru dealership said that has no effect on the ecu to fail. Is that true?”

“I replaced the battery on 7/11/15. I needed a smog certificate this month for my registration renewal and my vehicle would not pass for certification. I had driven the vehicle over 700 miles after battery replacement and was told that I needed to drive it an additional 50 to 100 miles non-stop to reset the vehicle to pass the inspection. I asked at the dealership can't you reset the vehicle here so that all this driving and mileage is not required, the dealership stated no. The volkswagen have a reset button on a panel but not the Subaru or any other vehicles. …”

“I was making a slow speed (~25 MPH) left turn with my 2007 Subaru Impreza 2.5i station wagon on a dimly lit intersection at night during the rain. I misjudged the turn, and turned about 2 yards too early. I drove off the road and into a ditch, colliding headon with a concrete storm drain. The driver side airbag deployed at the moment of impact. After the impact, the electrical including the headlights, stereo system and cabin lights were functioning. I was able to exit the car, and spoke with a witness who was able to call the police department. …”

“Left and right cylinder head gaskets were blown at 41,295 miles. Low mileage for this type of major engine failure. At 56,976 miles the ignition coil, spark plugs and ignition cables required replacement due to mis-fire condition associated with a cracked ignition coil. The exact same failure occurred at 81,856 miles. Both failures were accompanied by blinking check engine lamps requiring the vehicle be towed to the dealer for repair. Repeat failure of major components reflects persistent defects in design or manufacture.”
