2021 Subaru Outback

Car experienced unintended acceleration and the pre-collision safety system failed to engage. Car accelerated into a building and the driver stopped car's attempt to continue forward progress by taking the car out of drive mode. The pre-collision system failed completely. The Electronic Control Units seemed to fail entirely. This happened while pulling into a parking space at a very low rate to speed (until the car "took off").

The contact owns a 2021 Subaru Outback. The contact stated that while driving approximately 68 MPH with the cruise control activated, the vehicle suddenly lost motive power. No warning lights were illuminated. The contact stated that it was difficult while attempting to shift the gear lever out of drive(D). The contact stated that once she was able to shift the gear shifter, she shifted into park(P) to turn off the vehicle. The vehicle was restarted after multiple attempts. The contact then noticed that the parking brake had engaged independently. The vehicle was taken to a local dealer, where the failure could not be duplicated. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 14,000. The contact stated while driving on Mass Pike the Adaptive Cruise control was engaged, in the middle lane and no problems the vehicle lost power. After five minutes and traffic moving, the vehicle was trying to reboot but the emergency brake was on without anyone applying it. And the contact had a difficult time putting the vehicle into to park to restart the engine.

I purchased the car new in January 2021. During the first several months there were no issues. After that, the "Infotainment" system which controls the sound, nav, hvac, etc. systems would suddenly go black and those functions would stop working. It would seem to reboot as a computer does when you restart it. That was distracting but mostly just annoying, lasting less than 30 seconds. I will call that a "soft reboot." That happened many times over the next few months. On two occasions, the screen would black out and not only those systems would cease to function, it would shut down cruise control and Eyesight. Call that a "hard reboot." This was very dangerous. In traffic at 70-75 mph when the cruise control suddenly stops working, the car decelerates immediately and quickly. There are no warning signs or messages; it just goes black and shuts down those systems. Cars following would quickly be within a dangerous proximity. Not a safety issue but a hard reboot also wipes clear some settings including the nav destinations. During that period I spoke with service managers at two Subaru dealerships who said that it was a common problem and Subaru had issued a "patch" that was supposed to fix it. I live approximately an hour from the nearest dealership and had some difficulty finding a time to take it in for the upload. Finally I took it in to Scenic Subaru in Mt. Airy, NC on September 9, 2022 to get the update, with around 22,500 miles into a 36,000 mile warranty. I left the dealership at approximately 4 p.m. headed for Winston Salem, NC, approximately an hour drive. Within 5 miles from the dealership it did a soft reboot. That happened two more times. I called the dealership to advise them but it was too late to return. Then, still within an hour from the dealership, it did a hard reboot, shutting down everything as I described above. It functioned properly until it did a soft reboot today, 220 miles after the update.

The Navigation system will randomly go blank and then restart while driving. This not only affects any navigation which is currently in progress, but also disables the Cruise Control, Eye Sight, Lane Departure and other Safety devices. This has occurred numerous times while driving on an interstate highway and is dangerous and life threatening.

We bought this vehicle new and since we have had issues with the infotainment shutting down multiple times while driving. The infotainment screen along with all safety features associated with the electronic panel turn off. We have taken it to the dealership multiple times and keep getting told that they can't replicate the problem. We have recorded the issue and sent proof but Subaru manufacturing keeps delaying any inquiries in hopes to bypass lemon law.

*Eyesight system detects collision hazard and applies brakes when entering certain curves. *Unexpected braking in curve, particularly when roadway is wet poses a danger to driver and other motorists. *Not reproduced by dealer or service center, problem is captured on dashcam video. *Vehicle has been inspected by dealer *Eyesight system seems to "glitch" frequently, causing a variety of warning lamps on dashboard, full shutdown of infotainment system, and disabling all built in eyesight safety features.

THE MAIN COMPUTER SYSTEM THAT CONTROLS THE EYESIGHT SYSTEM, CRUISE CONTROL, LANE DEPARTURE, ALL HVAC CONTROLS, NAVIGATION, ETC. SHUTS DOWN (GOES BLACK), AND REBOOTS RANDOMLY. WHEN THIS OCCURS, ALL OF THE FUNCTIONS AND CONTROLS ASSOCIATED WITH THE COMPUTER SYSTEM ARE LOST. CRUISE CONTROL DROPS OUT AND THE BUILT IN SAFETY FEATURES ARE DISABLED. IT IS DISTRACTING TO THE DRIVER AND REQUIRES THE DRIVER'S ATTENTION TO RESET FEATURES THAT WERE LOST. IT IS A KNOWN PROBLEM BY SUBARU AND HAS NOT BEEN FIXED ON MY VEHICLE FOR OVER A YEAR NOW. THIS COMPLETE COMPUTER BLACKOUT EVENT OCCURS ALMOST EVERY TIME I DRIVE THE VEHICLE.

The Subaru Eyesight system malfunctioned while I was driving. All Eyesight components were enabled at the time of the incident, including pre collision braking and forward collision warning. I had been stopped at a red light at a four way intersection. I was the first car waiting at the red light, with other cars behind me and to each side. The intersection had multiple lanes in each direction. There were four lanes going the direction I was driving, and I was in the second from the right. When the traffic light turned green, I took my foot off the brake and onto the gas to begin accelerating. I accelerated through the large intersection reaching approximately 20 miles per hour. The speed limit is 25 or 30 there so I was continuing to accelerate to that speed and was just about through the intersection when the pre collision braking suddenly engaged with no warning at all. My foot was still on the gas trying to accelerate when this happened. All of the lights that show on the windshield seemed to light up red, and it showed that the pre collision braking had engaged on the dashboard screen behind the steering wheel. The car came to an immediate stop in the middle of the road and would not move forward. I took my foot off the gas and my car would still not move. My dashboard said something along the lines of “firmly press brake to hold stop.” I hit the brake, then everything returned to normal and I could move forward. I moved forward, safely switched to the right lane and pulled into the nearest driveway to get off the road and park. I then disabled all Eyesight features and called my Subaru dealership who said they will “diagnose and recalibrate” the system on 1/14/2022. My car and windshield were clean and my windshield is the same from the factory with no defects. No cars were in front of my- the road ahead was wide open, clear, flat, and straight. No one turned in front of me or anything. Fortunately I was not rear ended but it was very scary and dangerous.
