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.

2005 Subaru Forester Owner Comments

problem #11

  • 160,000 miles


The contact owns a 2005 Subaru Forester. While driving approximately 35 mph, the engine made an abnormal noise and the vehicle shook. The contact released pressure from the accelerator pedal, but the vehicle accelerated independently. The contact maneuvered the vehicle onto an emergency lane and parked. While the vehicle was parked, the failure recurred. The contact shut the vehicle off and restarted the engine. The vehicle was taken to the dealer, but the failure could not be diagnosed. The manufacturer was not made aware of the failure. The approximate failure mileage was 160,000.

On July 28, 2014 I was pulling into my parking space at my condo.the brakes wouldn't stop the car and the engine seemed to surge forward. The passenger with me looked down and said the gas pedal looked to be all the way to the floor. The car had to be towed, and I am still awaiting for the damage estimate from my insurance company.

The contact owns a 2005 Subaru Forester. The contact stated that while driving approximately 35 mph, the accelerator pedal was engaged and there was no response. The vehicle was coasted to the side of the road where the engine was turned off. After several few minutes the vehicle resumed normally. The vehicle was taken to an independent mechanic for diagnosis. A trouble code detected a malfunction with the throttle sensor. The mechanic was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not notified of the problem. The approximate failure mileage was 58,000.

I was pulling into an intersection with an oncoming car at a safe distance for me to safely pull out. Upon pressing the accelerator pedal the car did not respond. It only idled. And moved the car along at idle speed. Suddenly the approaching car that was at a safe distance when I pulled out were getting very close. Fortunately the driver was alert and slowed down so I could pull off the road - at about 3 mph. I fairly certain that it was a sensor in the gas pedal that went wrong. Similar to Toyota's problem, but instead of accelerating uncontrollably, it would not me out of harms way fast enough.

After buying it new and owning it for two years with no problems, in 2007 we had spontaneous acceleration problems with our 2005 Subaru Forester, resulting in 2 low-speed crashes into buildings and one that I managed to stop before hitting anything. No one was injured, but we had repair costs and insurance premium increases. The dealer said they found no problems, even though when I tested it with them, we reproduced a similar event. My detailed communications with Subaru of America (including information from the internet about other earlier similar Subaru problems) resulted in their denying any problem. I had a class-action attorney in juneau, ak write Subaru of America with the same results of denial by Subaru. All of this occurred in Alaska (our main home). The dealer was very kind and in 2008 took it as a trade for a Honda fit since we could not sell it with that history. I assume that other Subaru owners have had similar problems, which should begin to surface now. Thank you, and I look forward to hearing from you.

I recently (end of November, 2004) purchased a new Subaru Forester. When the car is started, maybe six times in the four months I have had the car, it immediately lurches into full speed the second the accelerator is touched, and sends you twenty or more feet forward (once backwards) before you can possibly brake. I have narrowly avoided several potentially fatal accidents. Today I had a real accident. When I went into carter Subaru this morning, they would not listen to me. Told me they had never heard of such a thing ever happening to a Subaru, that something that only happened once a month was impossible to check. The manager basically called me a liar and asked me to leave. It isn't just this accident, the car can be repaired, but this is a car defect that can certainly kill someone. On at least two occasions, once in grocery lot and once leaving my driveway, it was only by chance I didn't hit a pedestrian. I feel the car is unsafe and shouldn't be driven, but even more disturbing is Subaru's attitude that nothing can be done, and that I am a liar. Bruce mcalister

My 2005 Subaru Forester suddenly accelerated as I approached a stoplight. The car was in neutral, the clutch was not engaged and my foot was on the brake. The acceleration subsided after I placed the car in first gear and slightly pressed on the gas pedal moving the car forward about a foot. This sudden acceleration occurred over a dozen times in the course of 24hrs. The car was taken to the local Subaru dealer where several test runs were performed as well as a monitor test. No codes showed up so I took the car for a test run with one of the service advisors and the car accelerated several times within 10-15min. I took the car for a second test run with a mechanic who believed the throttle was improperly opening. The mechanic then inspected and cleaned the pin connectors at tps and map sensors. He then road tested it several times to determine if the problem had been resolved and found no more sudden acceleration problems. It was determined that the problem most likely was a sticky throttle.the car now runs well.

My 2005 Subaru Forester suddenly accelerated on its own while my foot was on the brake. I had to push really hard on the brakes to avoid surging ahead into traffic.
