2023 Subaru Forester Driver Assist & ADAS Problems

Eyesight camera randomly turns off and on while driving. Has been consistent over several months pierced to be an ongoing issue that was previously recorded from 20 14–20 21 super Forrester. Very similar issue now with my 2023.

In driving our 2023 Subaru Forester at 45mph at 10:00 am in the morning, with NO cars in front of us, in back of us, or on either side of us- suddenly the brakes locked up! Had there been anyone behind us, there could have been a dangerous collision. We have owned this car for 2 years, done all maintenance on it, and have NEVER had this happen before. We feel unsafe driving it now. We pulled the car over, got out to look under the car, thinking maybe we hit something in the road...but there was nothing...no warning....we contacted Subaru corporate, was given a Case number, but are still waiting to hear from them.

I was driving on a two lane highway in the mountains and came around a small right-veering turn in the road. I straightened out the wheel to resume traveling straight, and my car’s auto-steer kicked in and pulled left into the center divider, and then right across two lanes and crashed into the side of the mountain. The auto-steer has pulled me out of lanes prior to this incident as well.

While driving on a highway, one lane in each direction, my lane was going to end. In front of me were painted yellow highway lines directing me to head right to the new lane on the right side of the steel railings. My adaptive cruise control with lane keeping assistance still had me heading straight instead of to the right. I had to strongly turn my steering wheel to the right to avoid hitting the railing. Also I was following a car into a rotary with my adaptive cruise control on. Thankfully I wasn't going fast and the car started to speed up a little as the car in front of me turned around the rotary. I was able to steer it in the right direction. My point is, some of the new technology is showing commercials with drivers with their hands off the steering wheel, relying on the technology. I was glad I had complete control of the car, but these features aren't perfect.

We were traveling on a limited access highway at approximately 65 miles an hour. Both the adaptive cruise control and the driver assist were engaged. A car approximately four car lengths ahead of us exited the highway into the breakdown lane. My car slammed on its brakes and reduced speed to less than 40 miles an hour with no warning. Had there been a vehicle behind us we certainly would have been hit. This is not the first time we have had difficulty with the adaptive cruise control braking unpredictably , but it’s the first time it endangered our lives.

If you have the adaptive cruise control (or regular cruise if you disable adaptive) and accelerate to pass another vehicle, as soon as you take your foot off the gas to coast back down to the cruise setting the car slams on the brakes to bring the vehicle back to the set speed. I have almost been rear ended several times when this happens. This has occurred since I purchased the vehicle. The dealership says this is a design feature and not a defect. It doesn't matter what speed the cruise is set at. If you are exceeding the set speed, the brakes apply when the accelerator is released.

On January 3, 2024, my Subaru forester suddenly lost emergency safety features such as the blind spot warning system. Many warning messages flashed on the screen as I drove north on rt 1 and the blind spot warning system was totally disabled. I believe that other safety features were likewise disabled, as well. I was upset as I had traded in my 2015 Forester because it lacked those safety features that in my new car had abruptly just stopped working! I drove my car to the Concordville Subaru dealership for diagnosis and repair. I was told that the tech found error code P0455. The tech also found that the gas cap was secured and he reset the code and test drove the car. The error code did not re-occur upon test driving the car. I was told that that error code meant that gas fumes had escaped from the tank and that, when that occurs, all safety features are disabled. As my gas cap was secured that explanation seemed very weak to me and I asked how that explanation could be correct. I was told that Subaru could do a "smoke test" to ensure no leaks of gas fumes. I was given a loaner car and the test was done and no issues were found. As my car was running fine, I took my car home. I am writing this complaint over a year past the incident because I have now had a second incident, different in detail, but I am fearing some major problem with the car. I will write a complaint regarding the second incident which occurred on January 5, 2025.

Subaru Infotainment system frozen I've been experiencing an issue where the screen suddenly freezes and emits a loud beeping sound. I've tried restarting and resetting to factory settings multiple times, but the issue persists. The situation is worsening; my infotainment system has been unusable for a couple of days now, which means my backup camera is also not functioning. My friend mentioned that I could report this to the NHTSA, as it directly relates to safety concerns.

Forward collision braking activated for no reason. No traffic in front or behind when activated. Steady speed of 35-40 mph when activated - conditions were clear and dry. No warning prior to incident, message appeared on dash during braking. Seat belts activated and car came to a complete and very abrupt stop. Thankfully no vehicle behind us or most likely would have been rear ended. Problem has not been reproduced as we will not drive the vehicle without disabling the Forward Collision feature on the car. Vehicle had less than 2500 miles on it when incident occurred. Vehicle has not been to the dealer for inspection yet but will have them check the Forward collision system at first oil change service unless requested sooner. Emailed Subaru customer service to notify them of the incident.
