Subaru Ascent Acceleration problems by year

With ACC and Lane Centering on while driving on US 98 in Mississippi at approximately 3 PM on 11/09/2026, the vehicle experienced a sudden haptic-like vibration or lurch. Passenger felt her body move forward against the seatbelt. Driver cannot confirm whether brakes applied. After the incident, driver disabled Lane Centering for the trip while retaining ACC. Recurring issues: lane centering deactivates on curves, ACC accelerates before detecting new lead car after lane changes, false steering wheel hands-on warnings (prescription sunglasses interfering with monitoring system). NO CRASH OR INJURY REPORTED.

The contact owns a 2026 Subaru Ascent. The contact stated that while attempting to make a turn, the vehicle unexpectedly accelerated. The contact forcefully depressed the brake pedal to bring the vehicle to a stop. The contact's shin struck the steering wheel during the failure. The vehicle was taken to the dealer; however, the failure could not be duplicated or confirmed, and the vehicle was not diagnosed or repaired. The contact expressed concerns that the vehicle was unsafe to drive. The approximate failure mileage was 15,000.

My vehicle will abruptly break coming to a complete stop if a vehicle behind me approaches too quickly or gets too close to my vehicle. Yes the its uptoday on inspections and no errors show with in the vehicles computer system.

The contact owned a 2025 Subaru Ascent. The contact stated that while pulling into a parking spot with a foot on the brake pedal, the engine suddenly revved loudly and unintendedly accelerated. The vehicle crashed into a pole head-on and came to a stop. The vehicle was towed from the scene and was deemed a total loss. The contact sustained cuts on the hands, a sore back, a brain bleed, and body soreness. Medical attention was sought. The dealer was notified of the failure. The failure mileage was 22,000.

While cruising on a 2-lane road or a freeway, the vehicle will cross over the adjacent line, either left or right. This generally happens between 50 to 75 mph. The event happens either when cruise control is on or off. Wind is not necessarily the problem. The solution requires one to take the necessary immediate steering correction. At times, the departure from the lanes may repeat. This may be a temporary correction. This may create a head-on collision if not immediately correctly manually. VERY DISTURBING!

In 2024, 2025, and 2026, I have had 2 incidents in each year where the cruise control is set to 60 to 65 mph and the cruise control then accelerates the car past 100 mph. When this occurs, tapping the break does NOT disengage the cruise control. All 6 times I have had to slam the breaks to a full dead stop while the car tries to accelerate anyway. April 4, 2026 and April 14, 2026 are the most recent occurrences and all occurrences so far for this issue have been during a downhill road incline. The dealer has...

The contact owns a 2026 Subaru Accent. The contact stated that there was a failure related to the brake pedal design. The contact stated that there was an approximate one-inch difference in spacing between the brake pedal and the accelerator pedal in previous model vehicles. The contact stated that there was an approximate four-inch gap between the brake and accelerator pedals, while previous models had an approximate three-inch space. The contact stated that the difference created a hazardous driving condition and...

I have had my lane assist come on by its self a few times, which is very dangerous because it seems to take over and will pull on the steering wheel. I've also brought my car back to the dealership a handful of times to have it hooked up to a computer and also someone ride with me because the car will either hesitate to accelerate or stutters and doesn't seem to want to go when I am between 20-30 miles an hour. Other times when I'm at a light or stop sign it hesitates also. I was told there was nothing wrong with it and they reprogrammed to transmission but it didn't help at all.

The vehicle was being driven on a public road, going roughly 45mph. I felt a very harsh studder/clunk and completely lost responsiveness from the accelerator. There was no throttle response even pumping the pedal all the way to the floor. I was able to coast to a parking area and make a safe stop. Once I was stopped, I turned the car off, back on again, and it got me the rest of the way home. This was the most severe instance of the problem, but both primary drivers of the car have experienced the accelerator going...

There was a SUDDEN and UNINTENDED acceleration without the driver input while braking to park going approximately 1 - 2 MPH. Our safety was at risk. The vehicle was not in our control. A police report was generated. Rather than stopping we crashed into the apartment building causing significant damage to both the apartment and our vehicle. There were no warnings, no automatic braking to avoid the collision, the air bags did not deploy. The total damages are still being determined by the dealer and insurance company.

unknown defects in some vehicles that could cause sudden and unintended acceleration without driver input Yes, our safety was at risk. The vehicle was clearly not in our control. A police report was generated. The car plowed through the garage no control to brake The damages are being inspected by insurance. There were no waring lights that I could see

The driver was driving into a parking lot preparing to park, when the vehicle accelerated and started going forward at a higher speed. The vehicle struck a parked vehicle, then travelled across the parking lot, over curbs, a grass median, landscaping, and struck a rock building at a high rate of speed, causing a partial collapse of the wall. The vehicle is available for inspection through the insurance company. No analysis of data was done and nothing was inspected. There were no symptoms of the problem beforehand. The vehicle has automatic emergency braking, but it evidently didn't operate. It is unknown if this was caused by driver error in accelerating and never braking.

The vehicle hesitates like it doesn't want to get up to speed, despite pressing the gas pedal to accelerate. The RPM needle bounces. Dealership has not been able to "replicate the hesitation I feel when accelerating." They originally tried to say I didn't tell them the problem was happening when it had time to warm up, which is a lie, I have all the scheduling notes made by the employee who set the appointment up. Dealership said it passes diagnostic testing despite my serious concerns as the owner driving it...

Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance, Eye Sight, RAB, some ! Symbol, and check engine light are all on and not working. You know everything that makes a Subaru. This is not the first or even second time. We are on the fourth instance of this happening. We live 2+ hrs away from the closest dealers. The first few times it occurred, we called to make a appointment. Each time was always a few weeks out and the issue would...

My wife was pulling into a parking spot at a Safeway in Seattle. The car, instead of stopping, sped up when she stepped on the brakes, slamming into a brick wall. She shifted into reverse, and the car sped backwards, then shifted to drive, and sped forward and slammed into a wall again. She shifted to park and pulled on the parking brake. Then, after 5 minutes with the car off, she drove home without incident and parked, although the car was severely damaged.
