There are 4 owner-reported driver assist & adas complaints for the 2023 Subaru Ascentin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.

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.
