2023 Subaru Ascent Driver assistance Problems

On XXX, I was operating my vehicle heading Pocono PA, on I-80 in [XXX]. At approximately mile point 142.4, the vehicle's onboard Forward Collision Avoidance System (FCAS) suddenly and unexpectedly activated without any obstruction, hazard, or vehicle ahead. The abrupt, automated braking and system intervention caused an immediate loss of vehicle control, forcing the car into a 180-degree spin. The violent shift in momentum caused the vehicle to roll over on the highway before coming to a stop. No other vehicles were involved in the initiation of the crash.

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 dismissed the problem every time and has been unable to fix or reproduce the problem on demand. The random frequency of this problem can easily lead to a significant accident for the driver or others in the vicinity. And the lack of resolution from the Subaru dealer has lead me to report the issue here in hopes that if this is occurring for other vehicles that the company takes an actual resolution to solve the issue in their cruise control function.

I was entering an intersection to make a left-hand turn. I was driving at a low speed. My foot was pressing the accelerator and the car entered the intersection. In the middle of the intersection, the car wheels suddenly stopped turning. There was nothing in front of the car. Cars behind me began honking since my car stopped suddenly and unexpectedly while I saw a notice displayed on the car messaging, but I do not know what it said. I am unsure if the car engine turned off or not, but I remember turning on my hazard lights, putting the car in park and pressing the start button. I was able to drive out of the intersection to a safe location and turned off the car engine. I restarted the car and drove immediately to the dealer where I purchased the car from for them to evaluate it. It is currently being submitted for diagnostics at the car dealer. I told them I would make this safety report while I waited.

When crossing a bridge at 40 mph with wide open lanes and shoulders the vehicle on cruise control suddenly braked aggressively and came to a full stop in the middle of a state highway bridge. Conditions were daylight, headed towards sun, no shadows on bridge. The road surface was smooth asphalt. There were shoulders as wide as the active lanes. There was no warning and very little time for a driver reaction. This type of vehicle behavior will most certainly cause rear end collisions.

Incident Description – Event 1 On August 28, 2025, at approximately 4:45 p.m. while driving on Sugar Ridge Road, my 2023 Subaru Ascent suddenly jerked violently into the left lane without warning while the EyeSight Driver Assist system was active. I had to take immediate corrective action to maintain control and avoid a head-on collision. This behavior has occurred on multiple occasions under similar circumstances. My husband has also experienced the same issue while driving, which demonstrates this is not an isolated event. Incident Description – Event 2 On multiple other occasions, while the EyeSight Driver Assist system was engaged, the vehicle veered dangerously close to a semi-truck traveling beside us. I had to react instantly to prevent sideswiping the truck, which could have resulted in a severe accident. We have noticed this behavior occurs nearly every time we are alongside a semi-truck on the highway.

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.

Incident

Subaru Eyesight will turn off randomly while driving or while parked (turn the vehicle off, unlock the door, sit for a minute or two and when restarting the vehicle, eyesight indicator is orange - off. Example - getting fuel at a full service gas station. Yes the vehicle is available for inspection. Our safety is put at risk. Once Eyesight is off it will not reset/restart, so you are driving without the number one Subaru safety feature. We can reproduce the error. The Dealer just looked at the codes and said it was normal operation. We reported the error to Subaru Customer care and we have a case number. Subaru Customer care is going to contact the Dealer. There is a small red "i" indicator light in the dash that will light up after Eyesight fails. There are no warnings of the failure. We understand rain, snow and fog will impact Eyesight. We had a 2020 Subaru that Eyesight only shutdown when expected (heavy rain, snow, fog) and would restart once we were in the clear, but now we are told that sunlight and windshield condensation affects Eyesight's functionality. We were also told by Customer care that the cameras where changed on the 2023 Ascent model.
