While in a parking lot moving at very slow rate speed the car suddenly accelerated on its own. I had just slowly turned within a parking lot in preparation to backing into a parking space. I had just removed my foot from the accelerator and the car was almost at a stop and I was about to brake and put the car into reverse when it suddenly and rapidly accelerated on its own. My foot was not touching the accelerator at the time (it was over, but not yet touching, the brake). The car felt as if someone had suddenly slammed on the accelerator, but my foot was not on the accelerator at the time. Luckily my foot was over the brake when the rapid unexpected acceleration occurred and also luckily there were no cars in front of me. I was able to immediately slam on the brake so that the car did not hit anything. Before I was able to brake, the car quickly lurched forward at a surprisingly rapid rate of speed for a short distance. Quick application of the brakes stopped the sudden and rapid forward movement of the car. I did not notice any warning lights or messages on the car. This could have been a very dangerous situation. If someone had been walking in front of the car, they would have been hit and potentially seriously injured. If there had been cars parked in front of the space I was about to back into, the car would have hit them and caused damage. This happened earlier today and I have not yet reported it to the dealer. No police or insurance personnel were involved as I managed to avoid an accident. The event occurred today, Wednesday December 3rd at about 11 am. There were no other witnesses. To my knowledge this is the first occurrence of this rapid unexpected acceleration for this car.

I experienced sudden acceleration in downtown and almost hit three cars, caused me to run three red lights and almost hit pedestrians. I had the car, 2017 outback Subaru towed to the dealer and was told there are no recalls, but saw many problems listed on the federal safety agency website. It was terrifying and still shakes me up when I think what could have happened. Subaru told me this was the first they have seen this and that I do not have the extended warranty and I would be held for the cost. I am beyond upset. They tried to have me pick up the car after finding nothing. I told them they are to keep it until they find the issue. I have a loaner from them.

My vehicle accelerated when I was at a red light. My foot was on the brake. It also accelerated when I was backing out of our driveway. This resulted in a type of “ lurching” motion. The incident at the red light happened once. The incidents while backing out happened 3 times. No warning light were displayed. The vehicle has not been inspected yet. My safety was at risk because it accelerated once when my foot was on the brake and excessively when I was slowly backing up.

I was driving my 2017 Subaru Outback on a trip from New York to Florida. On I-95 in heavy traffic I hit a bump in the road, and at that instant, nearly every warning light on my dash came on, including EyeSight, lane departure, and emergency braking. My adaptive cruise immediately disengaged causing the vehicle to suddenly slow (this incident was at highway speed). The "brake" light was also illuminated. Not knowing what happened, I pulled over on the side of the highway and found that the wire to the electric parking brake on the passenger side had disconnected from the brake module. I tried to plug it back in, but it would not stay. I secured the cable with a hair tie and continued on the trip. Approximately 500 miles later, I hit another bump or pothole, and the same thing happened. I checked under the car again, and discovered that the driver side had failed in the same manner. I secured the cable with another hair tie and was able to complete my trip. When I returned home, I discovered that this is a known issue and there is a Subaru TSB published, 06-63-18R. There is no warranty on this issue, and I was charged nearly $750 to fix a KNOWN PROBLEM caused by a plastic retainer. In my opinion, this issue should be treated as a safety defect and subject to a recall to replace with the newer part. Having all of your vehicle assists suddenly fail at highway speed in heavy traffic is a disconcerting and dangerous event.
