Fuel system reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

SUDDEN AACCELERATION: Cold started the car in garage, all OK. Then backed out and into turn around where I placed foot on the brake. At that moment suddenly accelerated and engine revved to 2000rpm (sounded like). I had to push down very hard on the brake pedal (where my foot already was) to stop the car before crashing into a tree. Foot was clearly on brake pedal at incident (that was the only way I could stop the car). It was not on or close to accelerator pedal and no floor mat or other objects was on or near the accelerator pedal. Very concerned about safe vehicle with this sudden acceleration. Appointment with Subaru dealer made for full diagnostic check. Dealer is White Bear Subaru, [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Today while waiting at a stop light the auto start stop engaged. When the light went green I put my foot on the gas and the vehicle stalled. The car was on but not running, several alarms were on the dashboard. I had to put the car in park, turn it off and then restart the car. This is a repeated issue and has been going on at least once a month since we purchased the car in 2021. We've brought it to the dealer and they said there was nothing wrong because there was no OBD code. I have checked myself and I have not found any code. This is extremely unsafe

As I was approaching a T intersection and preparing to stop at the stop sign, I started to apply my brakes when all of a sudden my car accelerated and lunged forward almost into the path of oncoming traffic on the intersecting road. As I had originally started to apply my brake, it felt as if the brake dropped slightly under my foot but, as the car lunged forward, I immediately jammed on the brake so I am not 100% sure about that dropping sensation. It all happened within a matter of seconds. Anyway, jamming on the brakes stopped the forward momentum and the car stopped before actually entering the path of an oncoming car. If I had started to brake any closer to the intersection, I may not have had time to stop the car in time to avoid a broadside collision with the oncoming car. I have owned this car about a year and a half and this is the first time anything like this has happened. There was no warning lamps, messages etc at the time or prior to the incident. After the incident, my husband checked online and saw that others have described a similar experience with their Subarus and, apparently, there is an ongoing lawsuit involving this problem. This just happened last evening so I have not yet taken my car to the dealer to be inspected but plan to do so soon.

Crash reported

On Sunday, August 20, 2023 I was pulling into a parking spot in front of an Anytime Fitness at a local strip mall. As I applied the brake, the motor raced and accelerated driving me into a pillar outside of the fitness center. I was in shock, not understanding what had happened. Had I chosen to park one stall to the right, the car would have gone through the window of the business instead of the pillar. Considerable damage was done to the pillar and to my 2021 Subaru Outback, but I was not injured, and no one else was injured. I had the brakes checked at my vehicle service center and was told the brakes were functioning as they should be. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others. No warning was provided by the vehicle. The crash occurred in two seconds.

My wife turned into a parking spot slowly with her foot on the brake, and the car suddenly accelerated without warning. It went up on the curb while my wife slammed on the brake and stopped the car. She then put the car in reverse and backed into the parking spot. Came home without further incident but was very upset. I intend to question the dealer, Parkway Subaru in Wilmington, NC. I see articles online that relate problems like this to a number of different models and makes. My wife does not want the car anymore, but how can I be sure any car I replace it with does not have the same problem? 6/15/23 The contact called to add additional information to the complaint. The contact owns a 2021 Subaru Outback. The contact stated that while his wife was driving into a parking space at 1 MPH with her foot off the accelerator and depressing the brake pedal, the vehicle inadvertently accelerated. The contact stated that his wife was able to depress the brake pedal to the floorboard and bring the vehicle to a complete stop.

Crash reported

Car experienced unintended acceleration and the pre-collision safety system failed to engage. Car accelerated into a building and the driver stopped car's attempt to continue forward progress by taking the car out of drive mode. The pre-collision system failed completely. The Electronic Control Units seemed to fail entirely. This happened while pulling into a parking space at a very low rate to speed (until the car "took off").

Since we bought our 2021 Subaru Outback in May 2021, the vehicle hesitates when accelerating mainly after filling up with gas but also at other times. We have taken the vehicle in 4 times for service, but Subaru cannot duplicate the problem. Another issue we are having is that every time it rains, there is a puddle of water that forms on the passenger side floor board. We have taken the vehicle in 4 times for service, but Subaru cannot duplicate the problem.

Driving at 65 mph, engine stopped taking gas, slowed to below 30 in heavy freeway traffic. Resumed normal operation in about a minute. Then failed in similar fashion 5 minutes later. Took my 2021 Subaru outback xt to the dealer where purchased. They have been unable to duplicate the issue and want me to drive the car without any fix. I refuse to do that as if it happens in a situation where I must accelerate to be safe, it is going to be disastrous. They point to no recall on the 2021 model, but had this issue for the last 3 years on many of their models. What to do?

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
