Two problems related to automatic emergency braking have been reported for the 2023 Subaru Ascent. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2023 Subaru Ascent based on all problems reported for the 2023 Ascent.
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.
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.
