“At approximately 85,000 miles, the check engine light on our 2005 Subaru Outback xt went on and we took the vehicle in to our local repair shop to check the light and they recommended having the vehicle towed to our Subaru dealer. The vehicle was towed in and the dealer service person called stating that timthe turbo had failed (along with the cv boot & alternator belt). I provided the information regarding our official Subaru 100,000 mile gold plus extended service contract which we purchased for $1975. …”

“2005 Subaru Outback. The car was in park and my right foot was tucked back behind my left foot which was resting on the foot rest pad on the far left side of the floor. The engine was idling normally when suddenly it went to very high revs for 4 to 5 seconds and then returned to normal idle. Later the same evening, as I slowly entered my garage and applied normal brake pressure, the car first slowed (as expected) then suddenly began to accelerate. I applied hard brake pressure and the car stopped. …”

“I have been experiencing a problem while accelerating from a stop or from coasting, such as when a red light has just turned green. I begin to depress the accelerator and the engine just about dies. This has nearly caused me to get t-boned at intersections numerous times. I have brought it to the attention of two different Subaru dealers and they say that nothing is wrong with it. I have heard that other Subaru owners are having this problem but Subaru will not admit that this is a safety issue.”

NHTSA complaint #10160409, filed 2006-06, 20,000 miles

“I have been having a problem with my car for the 2-years and has been getting worse. The throttle pedal at times will become non-responsive and the engine idle cannot be controlled. At this time the check engine light is on with a code. P2138. I have taken the car to the dealer with no luck they could not find anything wrong. The car has left me stranded several times and I had to limp or be towed home. The RPM can be anywhere from idle to 3000 RPM and as I said the pedal has no control. I have replaced the accelerator pedal assembly and the problem was gone for the past six months. …”

“I took a cross-country trip this summer from la to kansas city, mo. I had the car serviced and everything checked out before I left both going and coming back. I left kc to head back to la. 3 hours outside of kc I saw my check engine light come on and the temperature gauge up to red. I pulled over immediately. Smoke poured out of my car. I put coolant and water in it 3 times. It seemed fine when I started the engine, then the needle would go up to red. I didn't dare drive it, so I called aaa. They towed me to a Subaru dealership in ks. I was told my head gaskets had blown. They fixed them. …”
