Driver Assist & Collision Avoidance complaints by model year
To start, I had to replace the engine in my 2024 Legacy that I purchased brand new in June 2024. Subaru of America handled the situation incredibly poorly, I was unable to use any warranty and I was out over 6,000 dollars. Second, my passenger airbag light has been on since September 2024. I was told to replace the sensor the whole seat rail would need replaced and would be over 1000 dollars. Apparently not covered under warranty either. Lastly, god forbid you have to drive West when the sun is going down. MULTIPLE times my vehicle has popped the “obstacle detected” while I’m traveling 75 down the interstate and spikes the brakes automatically causing a massive hazard. This is my third Subaru, but it will certainly be my last. Customer service was horrible and issues are not resolved properly.
NHTSA complaint #11751237 — an unverified report by a vehicle owner.
Driving my car at 39mph and approaching a vehicle stopped at an intersection perpendicular to my left, she accelerated into my path and Subaru eyesight provided no warning and did not attempt to break at all before the collision occurred. I was able to slow to maybe 15 mph but disappointed eyesight did not work as intended.
NHTSA complaint #11748634 — an unverified report by a vehicle owner.
The factory touchscreen infotainment system is experiencing severe screen delamination (internal adhesive failure). This defect causes uncontrollable 'ghost touching,' where the screen registers phantom inputs. The system cycles through radio stations, changes audio sources, and changes navigation without driver input, causing an extreme, sudden driver distraction. Furthermore, the system frequently freezes and crashes, which completely disables the backup camera display. This prevents a clear view behind the vehicle and creates a severe safety hazard for pedestrians. The dealer confirmed the issue. Contacted Subaru of America and they are unwilling to assist at all with fixing the issue, leaving the customer to pay full price to replace the screen. Does not seem like a fair business practice.
NHTSA complaint #11742852 — an unverified report by a vehicle owner.
All Safety features stopped working while driving multiple times and loading feature pops up on the display screen. Speakers will go mute randomly, no sound will emit including phone calls. Automatic stop feature has engaged on the interstate multiple times, locking breaks (This is extremely dangerous) and lane assist does not recognize the difference between a lane or tar strips road patches. Will Automatically move the car into the next lane, even when a vehicle is in the lane. I have reported the issues to the dealership I bought my vehicle from. Also have cam footage of electrical issues.
NHTSA complaint #11733299 — an unverified report by a vehicle owner.
I am reporting a Sudden Unintended Deceleration event in my Subaru. The vehicle grinded to a halt without driver input. The car stopped in the left lane of a major highway. We put on our hazards and called the state police for help. They were unable to get to us in time. We were hit from the rear. The car's failure created a stationary hazard that led to a high-speed rear-end collision by a Jeep and truck which caused the car to do a 360-degree spin.
NHTSA complaint #11721080 — an unverified report by a vehicle owner.
I drove into the parking lot of Walgreens, then drove around and pulled into a parking spot facing the south side of the building and put my foot on the brake to stop and park. Instead of stopping, the car suddenly lurched forward violently and slammed into the brick wall of the building. My wife called 911 since I told her my chest really hurt. When the police came, I told them my foot must have slipped off the brake and hit the accelerator, since I had no idea what else might have caused the car to accelerate like that. My wife drove the car home and then drove to the ER where the EMTs had taken me. A CT scan showed that I had a fractured sternum, since my chest hit the steering wheel full force after the air bags failed to deploy. I was in excruciating pain for a few weeks, and after I felt better, we submitted a claim to our insurance company. We then took our 2017 Subaru Legacy to a certified Subaru collision repair center. We were shocked to find that the car was totaled, since it was still drivable. Something kept bothering us about the crash, since EyeSight should have applied the brakes if I had accidentally accelerated and it detected a brick wall in front of our car. After some research, we stumbled on the information about the Class-Action Lawsuit that was just settled by Subaru for reports of Sudden Unintended Acceleration (SUA). The description of what happens with SUA was exactly what I experienced, but this was the first we had heard of it. We were never notified about the lawsuit, even though our VIN number shows our car was involved. Our Subaru dealership had all our contact information since we bought our Legacy from them and they have done all the maintenance work on it. Unfortunately, we released our car to Copart as part of our insurance settlement, so there’s no way to check the EDR data. PLEASE let others know about this major safety issue before anyone else is seriously injured!

The infotainment touchscreen in my 2018 Subaru Legacy experiences “ghost touch,” where the screen registers inputs without driver interaction and becomes unresponsive. While driving, the screen changes settings on its own and distracts the driver. As a result of the touchscreen malfunction, critical safety features including Blind Spot Warning and Lane Keeping Assistance became disabled. This directly impacted safe vehicle operation. The issue was diagnosed by an authorized Subaru dealership, which confirmed the head unit is defective and requires replacement. Subaru previously issued a warranty extension for this known defect. Subaru of America denied goodwill assistance despite the safety-related nature of the defect.

Multiple instances of the vehicle emergency collision avoidance system responding to a parked car or a car stopped in a left turn lane (i.e. waiting at a light). 5X+ The car audio alarm goes off, and the vehicle abruptly brakes while moving in traffic. Essentially the avoidance collision system detects parked vehicles (always in other lanes) as troublesome instances. this has occurred on winding residential streets, and slightly curved highway intersection 1X.

The infotainment head unit system and screen with the backup camera is completely malfunctioning. There have been instances where the screen glitches out while backing up and I have almost been in a collision. The head unit makes constant random noises, and screen pop ups that cannot be turned off. This makes for highly distracted and unsafe driving as it makes it quite difficult for the car user to maintain sole focus and attention to the roadways and driving. The extreme glitchiness and phantom touches/noises are just as a distraction and safety concern as driving while using a cellphone which is against the law. The infotainment unit should be fully recalled, not just have a warranty extension. The Subaru dealership has inspected the head unit and declared the failure that was part of a now expired warranty extension. The failures came without warning; however the glitches have gotten more frequent and worse over time.
NHTSA complaint #11680921 — an unverified report by a vehicle owner.
Aug 2025: 2018 Subaru Legacy, 55,500 miles. ISSUE: Rearview camera froze with high-pitch sound for about 10-seconds, then shut off, while in Reverse. I was not aware immediately of this. Did not hit the cars behind me but definitely could have. Unknown if reverse lights affected. Based on online searches, rearview cameras not working is criteria for a recall. BACKGROUND: My main screen is affected by Subaru Screen Delamination (can't use touch at all). My exact model got an extended warranty, but I was not aware of this extension until after it passed. Subaru of America and dealers refused to service it unless I paid full price out-of-pocket. Fast-forward to now, reverse camera being affected. I also see mention online of emergency broadcast radio being blocked, since it does not stay on one channel, due to screen issues. I do not recommend Subaru (not the only issue I've had on a once new vehicle).

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
purchased my 2016 legacy in 2022, I was offered the bronze warranty due to milage. My vehicle was bought back due to loud noises coming from the engine. Was told there was a peze recall and it was fixed. Brought it back to the dealership for the same sound and they found nothing wrong. A few weeks later leaving work, I noticed my muffler was hanging. I took it to a local muffler shop where the repaired it and repaired the heat shield which was loose and knocking up against the exhaust. Still taking my vehicle to the dealership for the warranty clear coat/ zetec and was told that I needed two-wheel bearings and that I was over milage, that it wouldn't be covered. I had both wheel bearing replaced and rear brakes within the first year of having the vehicle. Later part of 2024 my dashboard was lighting up, not allowing any of my safety features to work and I have no traction in the snow. I took the vehicle back to the dealership where I was told that it had a bad valve body, That the vehicle was over the milage for the extended warranty repair. I was sold a lemon, but there is nothing I can do about it.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
This issue started on the trip back from Nashville. Upon cold start in the morning the center console display won't start. This affected infotainment, climate, eyesight, cruise etc. The system didn't work during the entire trip of 3 5 hours and inability to operate climate control caused the car to build up fog on all windows reducing visibility significantly at times. Turning ignition off, lock-unlock sequences didn't help the issue. The system booted normally after it sat locked for few hours upon arrival. A visit to dealer didn't find any issues. The usual comment the car needed software update, which I couldn't verify.
