2015 Subaru Forester acceleration problems

Filed Feb 3, 2026 · Acceleration, Engine · MA

On 3 different occasions the car randomly accelerated at a high speed without stepping on the gas pedal. The first time was in a parking lot. The second time was on a busy road while traveling at 35 mph. The car accelerated to about 60 mph, fortunately once applying the brakes the vehicle slowed down to gain control. The third time it happened was recently on [XXX] while slowly backing down [XXX]. The car accelerated backwards at a very high speed narrowly missing a fence in the neighbors yard. These incidents have happened with large time frame gaps in between the occurrences. After the third incident I took the car to a dealer Planet Subaru in Hanover MA. After keeping the car for a few days, the dealer called and said that they could not find anything wrong with the car and there was nothing that they could do for me. This issue is obviously very serious, if the car surges forward randomly while someone is crossing in a crosswalk it could be potentially fatal.

We were driving at 75 mph in the left lane when our car suddenly dropped in speed to 40 mph as though the transmission had dropped into neutral. There were no warning lights or any indication about what was happening. We were in heavy traffic, with trucks and car hitting their brakes. This could have caused a very serious accident. We managed to move our car to the right shoulder. The car's transmission re-engaged and we picked up our speed. This happened 3 times in the space of a few hundred miles while we were on a road trip. I called Subaru. They had no idea what it was. We went to the nearest Subaru dealer and they ran a diagnostic test, even including a 12 mile test drive with the computer hooked up. Nothing showed up. They told us to continue our trip. Then it happened 2 more times! The last time, again, in the left lane, on cruise. The engine rpm clocked up at 7500 rpm before I was able to get the car off the road. The engine died and we had to be towed to a shop. Again, no warning dash lights. This is a serious flaw and very dangerous.

I was backing out of a parking spot, and there was a telephone poll behind me in my path. I needed to pull forward to navigate around this poll. After backing up some, I put the car into drive to pull slightly forward, and the car lurched aggressively, so much so that I got out to see if it'd caught on something. It did not -- there was absolutely nothing there. So I got back in and tried to continue forward, and the accelerator went full force. I floored the brake pedal, but the car behaved as though I was flooring the accelerator. The car drove itself over a cement block, through a staircase and into the brick wall of an abandoned building, continuing to accelerate for a few seconds while against the wall. Air bags did not deploy. I walked away without physical injury, thank goodness. There were no warning lights, symptoms of or dashboard indicators of a problem before or during the issue. Upon investigation online, we see that there is a pending class action for this exact issue. The vehicle has been inspected by our insurance carrier and been deemed a total loss. Insurance has asked that we turn the title over to them in order to receive our payout, and I believe they plan to destroy the car.

Suddenly lost acceleration and engine stopped - without any dashboard signal of low gas or engine issue. Car was able to start after couple of minutes. At the time of losing acceleration and stopping gas indicator was showing two bars - and car was not running with low fuel indicator. My whole family was in the car and stopping in the middle lane of a busy national highway of 65 miles speed limit on a Saturday late in night was very scary!
