“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.”
NHTSA complaint #11466335, filed 2022-05“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. …”
NHTSA complaint #11572939, filed 2024-02“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. …”
NHTSA complaint #11527114, filed 2023-06“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. …”
NHTSA complaint #11689866, filed 2025-09“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. …”
