I had a 2011 Subaru Legacy2. 5;at 1130 am,I was pulling into a parking space at a local convenience store near us that we often go to,when suddenly on turning right into the space I heard the engine "rev"at a fast speed even though I had lifted my foot from the accelerator. (I used to drive a manual shift,and it reminded me of the sound an engine would make when trying to upshift too fast between gears)before I could react the car surged forward into the space,and I was barely able to slam the brake before it covered the 6 to 8 feet and hit a guard post,crumbling the front end to where the engine is bent and the car a total loss. The airbags did not deploy. (fortunate,as when I returned home I found the letter from Subaru that my car was part of the takata recall)interestingly,the engine still started and the car was drive-able ,despite the radiator being cracked in half(we were able to park it after having it towed). I looked up the symptoms I experienced and feel that there may have been issues with the electronic throttle control mechanism or the app(which senses the position of the accelerator ,as I am sure you know)my check engine light never went on. The car had acted as if it had idling issues a couple of times but not with regularity, and it had never stalled or displayed any other warning of this. I had just driven the car about 7 miles before this happened. I will never buy another Subaru;I have had other cars with troubles in the past but this is by far the most dangerous. I am just thanking the lord that the airbags didn't deploy and we weren't crushed(my 17 year old daughter was in the passenger seat). And,the car only had 24,350 miles on it! practically new condition!sad,because I really liked this car.
I've owned my 2011 Subaru Legacy since may of 2011 with no incidents related to speed control. Late August 2014, I was pulling into my driveway of the home we've lived in for 13 years, and midway through the turn I heard a revving noise. My foot was off both the accelerator and brake and the car unexpected lurched forward at a high speed, crashing into our chain link fence and tree before bouncing back into the driveway. As the car started to accelerate, I depressed the brake to the floor, but nothing happened. I was alone in the car and the airbag(s) did not deploy. I was probably going 25mph when I hit the tree. The metal fence post was flattened and the tree had a significant chunk of bark removed. There were no skid marks or other on our driveway of concrete. I had an oil change at the dealer the Tuesday before the incident (8 days prior). I'm not ruling out that something could have been mistakenly tweaked or tampered with during this visit. To test the speed control issue, I have contacted the dealer to see if any troubleshooting/ diagnostics test can be ran. Apparently it's highly unlikely the scenario that caused it (if not driver error, which I'm aware of as a possibility) can be recreated and/or solved. I believe I've ruled out driver error because if I had mistakenly pressed the accelerator and not the brake, I would have switched over to the brake in time to stop the impact from being so drastic at such a high speed.
The contact owns a 2011 Subaru Legacy. The contact stated the vehicle was in park when it accelerated in reverse through a yard crashing into a retaining wall. The contact was able to turn the vehicle after it crashed into the retaining wall. The vehicle was taken to the contacts residence but had not been inspected. The VIN was unavailable. The failure and current mileage was 150.
