2018 Subaru Outback: sudden unintended acceleration

Filed Jul 15, 2025 · Driver assistance, Engine · NJ

Arriving at my childhood home, I followed the driveway to the left to park in front of the garage door. With my foot on the brake and slowly rolling to a stop, the car suddenly accelerated and jolted forward making contact with the garage door and the frame of the garage. This caused damage to the house, garage door and the front of the car. Thankfully there was no other car in the way or a pedestrian! Only the house and car were damaged. This was sudden and there was no warning or prior occurrence to make me aware of the problem. We spoke to the dealer service manager and at first he said he never heard of anything like that. After further conversation he admitted that another car had a similar issue. They kept the car for two weeks and couldn't repeat the issue. We then went on line and found there are several class action lawsuits against Subaru for the same thing - unexpected and sudden forward acceleration! But when contacting Subaru corporate for assistance in resolving this, they claimed they never heard of any class action lawsuits or problems such as this. We need help dealing with Subaru. They are playing with us.

About 8 months ago I was turning into a space in the parking lot of a large store (Kohls) the car lunged forward on it's own when I took my foot off the accelerator. I was able to stop the car with the brake pedal before ramming a lamp post. I did not report it to a dealership. Nothing like it has happened in the 8 months/3000 miles of driving since. It took me completely by surprise without any indication of system failure.

2 incidences where the car accelerated on its own. 1st time pulling into a parking Space, Slammed on brakes barely got it to stop otherwise I would have gone through a store front. 2nd time same night in heavy traffic going to the George Washington bridge crawling in traffic while keeping at least a car length Between me and the car in front of me it did it again and I had to pull up on the parking brake and again I hit the brakes as hard as I could otherwise I would have slammed into the back end of a tractor trailer. I have owned this car for about a year and nothing like this has ever happened. Absolutely terrifying To the point where I don't Even want to keep the car. Called Subaru told them what was happening and they said they never heard of this before but they Don't have any appointments with loaner car until October 10th.

Car jerked back and suddenly accelerated without warning as driver had foot on brake and was slowly pulling into parking spot. Car hit wall of parking garage causing front end damage. Parking collision warning did not sound at any point. Car was going 1-2 MPH and was 5 feet from end of parking spot when incident occurred. Sudden acceleration when driver has foot on brake can cause injury to driver, passengers or others in the path of the car. No hazards in parking garage were present that could have caused accident, which was witnessed by driver's work colleague. No police report filed. Incident was reported to Subaru, which ran diagnostic and could not replicate issue. No warning messages were present prior to the incident. It appears there are 2 current class action lawsuits filed against Subaru reporting similar issues with 2018 Outback. I am unsure what component failed to cause this issue; car is available for inspection on request.

The vehicle, a 2018 Subaru Outback Limited 3.6R, was being pulled into the garage at the owner’s home. With brakes applied, and while putting vehicle into park, the vehicle suddenly accelerated forward making contact with a suspended shelf attached to the back wall of the garage. The force of the vehicle was such that the shelf and back wall of the garage were completely separated from the home in one piece and pushed approximately 10 yards away from the home before the shelf broke away from the wall upon impact with the ground, perpendicular to the back of the house. The vehicle then traveled down two hills in the back yard, across a water saturated easement, over a concrete drainage culvert and came to rest at the base of an incline in an adjacent yard approximately 150 ft from the garage. Air bags did not deploy and the owner suffered minor contusions causing pain and stiffness, but no significant injuries are noted as of this report. The vehicle was totaled and significant damage was caused to the residence. No collision warnings were displayed prior to collision and emergency braking did not apply upon acceleration. This was the first incidence of sudden acceleration experienced by the owner so this issue has never been checked out by a service technician and will not be repaired. The vehicle had less than 8000 miles on the odometer. The vehicle is currently located in a repair lot and the owner’s insurance company has been requested to hold the vehicle for inspection prior to disposal. The cause of the sudden acceleration is unknown, but the owner is confident that the brakes were being applied at the time of occurrence, and that they remained cognizant throughout the incident as they were unable to stop the forward progression of the vehicle until it came to rest on the muddy incline.
