Acceleration & Cruise Control complaints by model year
I experienced unintended acceleration while operating my vehicle. I was slowly pulling into a parking space at a gym when, without warning, the vehicle suddenly accelerated rapidly forward. I did not intentionally press the accelerator at that time. The unexpected acceleration caused the vehicle to surge ahead and collide with a light post, resulting in significant damage to the front bumper. Fortunately, there were no pedestrians or other vehicles in front of me, so no injuries occurred. This incident created a serious safety risk, as the sudden and uncontrolled acceleration could have resulted in harm to myself or others if anyone had been in the vehicle’s path. At this time, it is UNKNOWN whether the issue has been reproduced or confirmed by a dealer or service center. It is also UNKNOWN if any warning lights, messages, or prior symptoms were present before the incident. The vehicle is available for inspection upon request.
NHTSA complaint #11730321 — an unverified report by a vehicle owner.
Unintended acceleration, on 2 occasions. First occasion, car was in DRIVE waiting at a traffic stop and the engine radically increased it's RPM from idle to over 6000 RPM, remaining there. Braking control maintained the automobile's position. Shifting the car into neutral caused RPM to increase further. The car was shut off, restarted, and seemed to function normally. On the second occasion, which occurred later the same day, the car was off and then started, and while still in PARK with my foot on the brake immediately jumped to over 6000, remaining there. Once again the car was shut off, restarted, and seemed to work normally. It was taken directly (and slowly) to the manufacturer's service center at my local Subaru dealership. They have not been able to re-create the problem as of this date.
NHTSA complaint #11724063 — an unverified report by a vehicle owner.
At the end of a drive of 75 mi, 55-65 MPH on an 8 lane highway the engine stalled. Stopped in HOV lane. Restarting failed several attempts. Called police 911. Dusk, with light rain, slick highway. Poor visibility. Wife and I prayed a lot. Scarier than my year in Vietnam. Restarted after about 10 minutes, and prior to police arriving. Made it home 5 min away. Neither dealer nor Subaru can recreate or define the cause. My family and I fear the thought of driving again in that car. Not knowing the cause means no one can fix it.

THIS IS THE SECOND SUCH EXPERIENCE WITH THIS CAR! On Friday, September 12, 2025 at 3:32 p.m., I was driving slowly in a parking lot preparing to park. As I started to turn the car into the parking space, my car surged forward without my pressing on the gas pedal. I pressed on the brake, and the car came to a stop.

NHTSA complaint #11591225 — an unverified report by a vehicle owner.
After shifting my car into reverse, I slowly started removing my foot from the brake pedal. At this time, the car started rapidly accelerating backwards so I put pressure back on the brake pedal to stop the car. When doing so, the ABS light came on my dashboard, I heard a griding sound like the car was still trying to accelerate, and there was a loud constant beep. I was able to shift the car into neutral and then into park to stop the car and then turned the car off. I contacted the dealership about the issue, but have not yet been able to further investigate or bring it into the dealership.

NHTSA complaint #11586322 — an unverified report by a vehicle owner.
Vehicle is equipped with Subaru EyeSight Driver Assist which includes reverse automatic braking. Vehicle was reversing towards a parked vehicle on the street and the RAB feature failed to apply the brakes and the vehicle collided with the parked vehicle. I am extremely disappointed that the safety system in this car failed to work as advertised/expected resulting in damages to both cars.
NHTSA complaint #11585165 — an unverified report by a vehicle owner.
As I pulled up behind a car that was stopped at a stop sign, I took my foot off the gas pedal, and put it on the brake pedal. The moment i put my foot on the brake pedal, my car surged forward. I had a moment to think, and I confirmed that my foot was on the brake pedal, I had felt the brakes trying to resist the surge. I put the car into neutral, and it jerked to a stop. No one was hurt, I stopped the car in time, but I wondered if this had happened in other settings, what danger it would have posed. This has previously occurred rarely and intermittently when, starting out on some cold mornings, i shifted from reverse to neutral to drive, when backing out of my driveway in the morning.The car surged forward and I had to be quick on pressing the brake pedal hard to get it to stop before hitting a mailbox post. No warning lights went on, in any of these incidents. I called a Subaru dealer, who said there had been no recall history re this uninitiated surge behavior.
NHTSA complaint #11561489 — an unverified report by a vehicle owner.
Vehicle was using the self driving feature of the Subaru Eyesight system. With the system engaged, the vehicle is supposed to accelerate and apply brakes accordingly as to keep a distance from the vehicle in front. Today, that system failed. The vehicle, with the Eyesight system engaged, accelerated right into the vehicle in front. There was no warning. The vehicle will be go for repair on 12/5/23. I have used the Eyesight system since purchasing the vehicle in 2019 with no issues, except for today. Luckily, I was driving at a very low speed but this safety concern can cause catastrophic injuries if it is not fixed.

NHTSA complaint #11536960 — an unverified report by a vehicle owner.
When running on a highway and you press down on the accelerator hard to merge onto a highway or go around a vehicle to move out of the way of vehicles quickly coming up behind you, the engine takes over and speeds up on its own. It has occurred three times on a newly purchased used car and it will increase speed up to 100mph. You have to press intermittently on the brakes to pull over to the shoulder and turn off the car for five minutes for the car to reset. If you try to just break, you get a burning smell. I see two class action lawsuits on similar acceleration issues for 2015 to 2017 Outback/Legacy series.
NHTSA complaint #11513949 — an unverified report by a vehicle owner.
I had a episode of sudden unintended acceleration while I was driving in the highway. If I would let the brake pedal go, my car would probably escalate its speed to maximum until it crashes. The RPM was almost 5 even though I was applying the brake. I could not make it stop by applying the brakes at all . I only could make it finally stop when I changed the gears to neutral and them to park and finally turn the engine off. I was lucky I was in the highway and when I got in the first light it was green, other wise an accident would've happened.

NHTSA complaint #11460011 — an unverified report by a vehicle owner.
This vehicle is equipped with the Subaru "Eyesight" system which is a number of safety features like automatic cruise control, lane keep assist, and others. About once a week on average while driving the entire system will shut down and the screen will go dark. You lose the radio, bluetooth, navigation, and all the Eyesight systems. After about 30 seconds it will reboot and things will come back online but this is a major safety issue because you loose systems that help with safety. The dealership said it's a known software issue and there's nothing they can do until an update is available. I called Subaru USA customer support in September and they said an update would be available by the end of October and nothing was released. I called in early November and they said they were still working on it but had no release date.
