2023 Subaru Outback: false forward collision warnings

Filed Aug 3, 2026 · Driver assistance · WI

Phantom Braking of Pre-Collision Braking 2023 Subaru Outback Turbo Wednesday, July 29, 2026. 9:30 am, sunny day Driving south on local city street. Brakes slammed on, car stopped, flashing yellow lights on left Combination Meter stating that Pre-Collision Braking was activated. There was no vehicle/obstacle/animal in the road. No parked cars, no cars backing out of a driveway. Road was completely clear. No strange shadows, no cracks in street. Pre-collision braking system hallucinated an obstacle and activated, throwing me forward into steering wheel, and dog in the back seat thrown forward into back of driver’s seat. Restarted car and drove off. Turned off system every time I drove the car until I took it to the dealer 2 days later. Problem was not reproduced by dealer . No messages or warning lights prior to incident. The repair order stated that there was a "sticky" substance on the windshield, but I had just had the car washed. I didn't notice anything on the windshield.

In the last approximately 8 months my car has deployed the forward collision warning--Slamming on the brakes-red lights flashing on the screen-seat belts locking--for no apparent reason. Nothing was in front of me!! Twice I was in a local construction zone with cars right behind me and was nearly rear-ended!! Very Frightening experience each time! I took it to the Subaru dealer but they found nothing wrong with the eye sight technology. They did a test drive and it did not do that for them.. But what are the chances that it would occur for them when it has only occurred once a month or so. Contacted Subaru Customer line and was basically told unless it could be collaborated by their mechanics -there was nothing they could do.! Unbelieveable!! Ironic if my safety features are going to get me in an accident!! I am fearful about driving the car as there is no rhyme or reason to the device malfunctioning and slamming on the brakes. I hope you have some information on this to help me.

My son was traveling at an appropriate highway speed when the truck in front of him stopped suddenly. He braked immediately and was able to slow down significantly, but not enough to avoid colliding with the back of the truck in front of him. He was going approximately 20 mph, still braking, when the collision occurred. His best recollection is that the vehicle's pre-collision system did not engage until after he collided with the truck. There was damage to the front end of the vehicle but it was not severe. My son moved the vehicle onto the shoulder of the highway and put it in park. The driver of the truck called the police. My sons got out of the vehicle. While they were talking with the other driver and the police, a fire started under the hood of the vehicle and within several minutes the entire vehicle was consumed. The wreckage was towed to 1022 Shannon Court, Livermore CA 94550. In July 2023 we were involved in an accident that impacted the front bumper, left front quarter panel, and Subaru EyeSight system of the same vehicle involved in this accident. Repairs after the July 2023 accident were performed by Kraft Body Shop in Santa Clara, CA. Repair and calibration of the Subaru EyeSight system were performed by Santa Cruz Subaru after that accident.

While driving at a high rate of speed on a remote road, using cruise control, my vehicle suddenly braked/decelerated for no reason. Could have been the automatic emergency braking, adaptive cruise control, or forward collision warning. The first time it happened, a warning bell sounded, red lights flashed, and the vehicle decelerated VERY rapidly. It happened again about 6 weeks later, but the second time there was no audio or visual warning, the vehicle just decelerated rapidly. If there had been a vehicle behind my vehicle I might have been rear-ended because there was nothing on the road in front of me to warrant rapid deceleration. Also, on both occasions, the deceleration was swift enough to cause items in the vehicle to dislodge.

I purchased the vehicle about a month ago and almost on a daily basis the precollision breaking system would cause the car to break when there was nothing there. It has picked up parked cars on the side of the road as well as breaked for no apparent reason. I have been almost rear ended a number of times. The precollision breaking system takes several steps to turn off and needs to be turned off every time the car is started. I spoke to the dealership and brought the car in to be looked at. I thought maybe the cameras were too sensitive. I requested for the precollision breaking system to be disconnected since I felt like it was a safety concern. They were unable to reduce the sensitivity or disable the system. They said they could disable it but in doing so I would lose several other features on the car. They could not tell me which ones.

I purchased a new 2023 Subaru Outback in December 2022. The two displays on my 2023 Subaru Outback (both the main entertainment one and the tiny dash one) randomly restart without notice and/or freeze and are unresponsive. This disables adaptive cruise control, EyeSight warnings, lane departure warnings, front collision warnings, rear back up camera, navigation, Apple Car Play, phone capabilities, and electrical display odometer. Even in reverse, the backup camera will appear at times and then freeze, so the image I am looking at on the display is not true. I noticed this the other day when I was in reverse and saw a mother and child walking outside of my review mirrors that never appeared on the camera. I have taken it to my Subaru dealer where they had trouble twice uploading new software onto the car. They finally uploaded the "new" software and the issue persists. This last issued occurred today 3/22/2023 - I was on a 10 minute drive and the software restarted at least 11 times in the short 10 minutes. I am unsure what else this electrical/software issue impacts but it seems to be a safety one if I cannot trust the rear camera, departure or collision warnings, or cruise control. Luckily, I have never been in cruise control when the system malfunctions, as I'm not sure what the result would be. This has occurred at random speeds, as slow as 12mph, as fast as 60mph. It has happened when I have been on phone calls and when I have not been on phone calls. I have photos and videos of the unresponsiveness, and have attached the invoice for when I got it serviced on 3/20/2023. This is a serious issue and it seems Subaru does not have a fix at this time. Since this is a new car, I was also told that if this happens after my warranty, it will be MY responsibility to pay for the updated software and to fix this glitch, and that they will charge me for service and the update.

The contact owns a 2023 Subaru Outback. The contact stated that upon purchasing the vehicle from the dealer on October 3, 2022, he noticed that the automatic collision alert to the Emergency Services, the diagnostic alert, the remote services, the SOS emergency alert, the stolen vehicle recovery alert, the Roadside Assistance alert, and the multimedia features were inoperable.
