Vehicle speed control, Back over prevention, Forward collision avoidance, Jul 6, 2026, crash
I was already parked in a spot in a public parking lot. I tapped the accelerator pedal to move the car a few inches. The vehicle responded by violently accelerating, hitting a vehicle directly in front of me in another parking space. I applied my brake but the car would not stop. The force of the acceleration pushed the car out of the it's spot and it hit a curb and tree appox 30 ft away. In defensive move I turned my wheels to the right and continue to try and brake. This caused my car to hit the car on the right side of me. Property Damage occured. No injuries. Vehicle defect.

The speed control (adaptive) doesn't work. The interior heater doesn't work. Several lights including the 'check engine' light come on the dash. The lane departure system doesn't work. (It appears the thermo control value subassembly may be at fault.) The car has approximately 25K miles on it.

While doing a casual drive, engine made a noise after work at night. Woke up in the morning and check engine light as well as the EyeSight light was on. Checked everything and noticed the coolant was low; but upon filling it, did not resolve the issue. Took it to a Subaru service center and was told that it the Temp Valve had been stuck and that they had replace not only one for my year model the same day, but also a ‘20 and ‘19 in the past week. Have looked online and noticed others have been unfortunate around the same mile range 60k.

My vehicle is equipped with EYESIGHT. I was driving to my home after work at night and suddenly the infotainment system screen went blank; including Braking Assist, Adaptive Cruise control, Lane assist, Emergency Braking etc including Navigation, also the HVAC shut off and EYESIGHT that controls these as well, shut off. It was suffocating in the car due to no A/C and thusf I tried to pull over at a remote text-stop place and tried restarting the car but in vain. All screens were dark, no warm air, I couldn’t see what direction I was driving to, as well as I solely relied on navigation. I brought this car for it’s safety features and warmth in this cold temperature in UPSTATE NY and this happened. I waited for 20 mins, charged my phone for only 4-5% with a fellow citizen who was waiting there as well and checked online just to see a lot of people reported the same issue with 2021 Subarus with EYESIGHT. And there is NO way one can fix it. I tried contacting the dealer but in vain. I am afraid that if this would happen again, I wouldn’t be in a situation to face this scary experience.

Received error code P2682, a faulty Thermo Control Valve. This happened on 11/17/2023. Car potentially could have quit running in traffic. Subaru has identified the issue with TSB 09-80-21R. They have changed the design of the valve due to the many failures. My car has 74,000 miles. My brother in law has the same vehicle with 57,000, and his car is in the shop today for the same issue. The service tech working on his vehicle stated that he does a couple of these repairs a week, and that Subaru knows this part will fail and should issue a recall

Eyesight driver assist went out rendering safety features inoperable. Touch screen also blanked out so unable to adjust a/c, navigation,radio etc. Car had been on long distance all hiway drive and at 7 hours systems failed. Weather was in the 60s, overcast and it was in the afternoon. Pulled into rest stop and turned engine off then restarted but still failed. Drove 2 more hours and next rest stop systems came back after letting car sit off for 10+ minutes.

The windshield has spontaneously cracked on 4 separate occasions. Subaru denies this is a defect and claims all have been caused by rock chips. This is not true. The cracked windshield has caused the vehicle on numerous occasions to slam on its breaks while traveling at 55 mph or greater as it “senses” a collision. This has nearly caused 3 accidents so far.
Air bags, Forward collision avoidance, Jun 23, 2023
Yet to be diagnosed but possibly the cockpit control computer. Dealer service department has not been able to diagnose. No components have been replaced yet except for a software update that did not correct the issue. Safety systems all report as not functioning, These include all "eyesight systems";the air bags, automatic emergency braking, lane departure and lane keeping. Additionally all center console functions are not functional, including HVAC and radio. The vehicle has been to the dealer twice where the problem could not be reproduced. No other inspection has been performed. No warnings or other messages appear prior to the failure. The failure persists for approximately 10 minutes, after which normal operation resumes. I write this following the fourth occurrence of the failure.
Fuel/propulsion system, Forward collision avoidance, Apr 14, 2023, crash
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.
Lane departure, Forward collision avoidance, Apr 27, 2022
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.

My windshield cracked within a few months and few thousand miles of purchasing my vehicle for no real apparent reason.
Forward collision avoidance, Jan 7, 2022
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.

Several times, at random, the infotainment system goes blank. Screen goes black and can NOT adjust any of the ADAS controls! After 10 to 20 seconds the system seems to reboot and slowly returns to normal operations.

2021 outback purchased Feb 2021. Within 2 weeks the touch screen, which controls the cruise control, heating, all eyesight controls went blank. This causes cruise control at highway speed to quit, causing sudden deceleration at highways speeds. Sometime the screen reboots, most times it requires driver to pull car over to reset. This also controls GPS and Heating/Air. There have been times when I have working canines in the car and loss of air conditioner in summer months has been extremely problematic requiring pulling car off road to open windows to ventilate. Multiple trips to dealer, and open case with SOA results in no resolution, as there apparently is no fix. Recently 11/1/21 instructed when this happens to push my front defroster button five times after reboot to record codes. How distracting while driving is this? Feel like this is severely underreported as owners frustrated. Receiving dealer instruction to look at touchscreen while driving causes the cars alert function to activate saying “keep eyes on road”. Why are they advising this unsafe action? Recent software updates as late as last week of October installed and does not fix issue, verified by dealer service manager. Multiple incidents, recorded on my phone video, last incident occurred 7/12/2021.

The emergency braking forward collision system has deployed several times when it should not. In some circumstance the braking could result in the person behind me rear ending me. The main problem is that if the car detects another car directly in front of you, the system will sometimes deploy even if the vehicle is not in the same lane as you. I've had the emergency brakes deployed incorrectly in the following situations. I am driving in the left lane of a 2 lane road with a speed limit of 45 mph and the road is banking sharply to the left. Because of the sharp bank, a car was directly in front of me but in the right lane, so this is a normal non dangerous situation but the brakes deployed. I exited a parkway, the exit ramp banks sharply to the right as most exit ramps do. Directly ahead of me but off the road is a disabled vehicle. There is no danger to me as it is safely off the road, but the brakes were deployed. In both instances there was no one following close behind me but if there was, either situation could have resulted in them rear ending me. I have taken to disabling the emergency braking feature because I no longer feel safe using it. Unfortunately this takes 7 key presses to accomplish and it resets every time you turn the car on. I contacted Subaru customer service to complain, but got ridiculous suggestions, like just turn off the emergency braking when you expect to be driving with a lot of cross traffic. If not rectified, sooner or later that's going to cause an accident.

On 3 Occasions the Eyesight automatic braking activated with no apparent reason. The first was at highway speeds, second at 45mph and the third at about 30/35mph. In the first case a car entered the lane but there was considerable distance. In the second a car made a right turn into my lane and was slow but there was about 1/4 mile or more space and the last one occurred as, my wife, followed the curve of the road to the right. There were no vehicles near by only a median. In each case there was no gradual slow down only a full force application of the brakes. This led to the car lunging forward. Fortunately in all cases there was no one behind us or we would have been rear ended. The associated red heads-up lights activated at the very same time as the brakes did. I have called the dealer for an appointment to bring it in. No one else has inspected the vehicle.

My problem is an intermittent one. The infotainment display goes blank and reboots. When this happens I have lost Rear Automatic Braking, the Eyesight System, cruise control, the backup camera display and driver monitoring along with other non-safety related systems (radio, environment control). The dealer has not been able to reproduce, but has gotten error codes to send to Subaru of America (SoA) along with print out of error messages received via the My Subaru website. The vehicle has been to the shop 6 times in the first 9,000 miles. There has been no inspection of the car by SoA, just dealer service. There is no warnings until the issue occurs. SoA has been notified via Certified Letter and has been unresponsive as to a fix since 7/19/2021.
Forward collision avoidance, Jul 22, 2021
Subaru has apparently integrated their Eyesight Collision avoidance system with their infotainment system and the infotainment system crashes constantly. When it crashes about 50% of the time Eyesight goes offline and kicks cruise control off. At highway speeds this is VERY dangerous. The vehicle will slow down 5-10 mph between when the system crashes and when someone realizes what has happened in order to put their foot on the gas pedal to keep their speed up. I've almost been rear-ended multiple times now because of this. Subaru has been aware of this issue for TWO FULL model years now and is going into a 3rd year with the SAME problem. The update they issues in Spring 2021 made the problem worse not better. Subaru must be forced to either fix the issue immediately or recall the entire system and replace it before someone dies in a highspeed accident caused by this system. Until two days ago Subaru of America's employees were arrogant, condescending, and beyond unhelpful. Wendy Clough has stated Subaru plans to issue an update in August has no actual confirmed timeframe. Subaru has done NOTHING to communicate with owners or dealers on mitigation options, if any, nor to warn customers of potential risks. Subaru must be forced to notify all owners of the issue immediately.
