Subaru Forester lane assist problems

Filed Oct 8, 2026 · Driver assistance · NY

On October 7, 2026 at approximately 7:40 PM, the EyeSight system inexplicably stopped working with a warning light notification. Prior to the EyeSight failure, the touchscreen froze completely with subsequent inability to control the climate and other control options. After pulling over and stopping the engine and then restarting several times, the problem did not resolve. After parking and shutting the engine and then restarting after a hiatus of not driving, the problem resolved. The EyeSight system failure created a risk due to loss of pre-collision braking and throttle management, lane keep assist and adaptive cruise control. No incident occurred. I am scheduling a visit to Subaru dealer on October 13, 2026.

Leading up to a windshield replacement, my eyesight cameras that help with adaptive cruise control and lane keeping assist kept failing. This feature would turn on and off repeatedly. When I got my windshield replaced, it took longer than expected because of the camera calibration. The microchip(s) inside one of the three cameras was fried and they had to put in a new camera. This failed camera was an original to my car and the justification provided was that "this sometimes happens." For the fuel/propulsion system, I was topping off my car with gas one day when something went very wrong. My fuel tank was just shy of full, and when the gas pump handle tripped to stop pumping gas, a large amount of gasoline came flooding out as I removed the gas pump handle. This was scary and highly concerning because I have never experienced this with any previous vehicle before. The dealership, in cooperation with corporate, identified one other instance of this issue occurring somewhere in the midwest. Their best guess as to what happened is that the air relief valve of my gas tank somehow became blocked and that is what caused the overflow of gasoline. The solution was to turn the air relief valve around from facing the outside of my car to the inside metal frame. July 2026 marks one year since acquiring my car, and these experiences thus far make me question the safety and longterm viability of my car and the Subaru brand. This is ironic, because Subaru's legacy and strong reputation of safety and build quality was my primary incentive for getting one in the first place.

On March 12, 2026, my 2025 Subaru Forester Hybrid, owned for less than 1 month at the time and purchased on 2/14/2026, sustained a star chip to the windshield during normal driving conditions. While the physical damage itself was minor, the vehicle is equipped with Subaru EyeSight, a camera-based advanced driver assistance system (ADAS) that relies on precise optical clarity through the windshield. I'm now required to have the windshield replaced, because the manufacturer and dealer requires it. According to both Subaru and the vehicle’s owner’s manual (page 15), windshield replacement must be performed using OEM (Original Equipment Manufacturer) glass to ensure proper calibration and safe operation of the EyeSight system. My insurance provider is attempting to authorize the use of aftermarket (non-OEM) windshield glass despite this. This presents a serious safety concern. The EyeSight system controls or assists with critical safety functions including pre-collision braking, adaptive cruise control, and lane keep assist. Aftermarket glass can introduce optical distortion or variation that can interfere with camera calibration and system performance. Using non-OEM glass in a vehicle designed around camera-based safety systems creates a risk that these features may not function as intended, potentially increasing the likelihood of a crash. This directly impacts federally recognized vehicle safety systems. There appears to be a gap between manufacturer safety requirements and insurance replacement practices. Consumers are being placed in a position where cost-saving measures may override safety-critical specifications. I'm requesting that the federal safety agency open a formal safety investigation into the use of non-OEM (aftermarket) windshields in vehicles equipped with camera-based ADAS systems. I further request that the federal safety agency establish clear regulatory guidance or requirements ensuring that windshield replacements follow manufacturer specifications, including the use of OEM glass.

I had two codes on my 2022 Forester over last two weeks. First one u0284 was for the Active Grill Shutter. This happened because for some reason Subaru decided to put the fog lights on the same fuse as the AGS. Fog light blew, shorted out blew the fuse, this caused every safety system in the car to turn off. By default these are open so why does loosing 1-2MPG, or longer time to warm up a car cause every safety feature to turn off. Answer is they kill everything so you have to come in and pay hundreds for $15 bulb. This week had a o2 sensor go bad while I was driving. Had lane assist on , adaptive cruise, etc. Check engine went on and car start to rapidly decelerate, and again all safety features where turned off for something that is not fixed would potential cause reduce MPG, damage the catalytic converter, cause black smoke. None of this should require all safety features to be turned off. This is going to kill someone. I know your not suppose to have your hands off the wheel when using lane assist but people do it. I was in bumper to bumper traffic on 40 going 65 MPH. Not only would I have been at risk but everyone around me. Worse case is I do not have my hands on the wheel, the o2 sensor fails, car pulls into the car beside me and someone dies because Subaru wants money more than safety.

My 2017 Subaru Forester Touring (VIN: [XXX] , 118,200 mi) has a recurring EyeSight failure where the system becomes disabled and will not complete camera registration or calibration. Subaru of Sterling (VA) diagnosed active code B28A0 “Vehicle Model Judgment” and noted that the EyeSight stereo camera would not accept vehicle model registration. The technician documented: “Error for camera adjustment incomplete. When attempting to relearn UI for Eyesight camera, system is not taking vehicle registration; suggests camera replacement and perform recalibration.” This occurred after a confirmed DCM/STARLINK parasitic draw had caused repeated low‑voltage conditions until the dealer reset the DCM to factory mode (per the RO: “No further draw present at this time”), suggesting EyeSight registration may have failed due to prior voltage instability rather than true hardware failure. Subaru's service flow for B28A0 indicates this code can occur when the model write/registration is incomplete, interrupted, or mismatched—not necessarily when a camera has failed. Subaru lists causes such as: CAN communication issues, incorrect model registration, incomplete write due to ignition timing, or power/fuse issues during aiming (EyeSight diagnostic manuals). I am reporting this to the federal safety agency because EyeSight is a safety-critical system that governs adaptive cruise, lane keep assist, and pre-collision braking. My dealer is recommending camera replacement without documenting that Subaru’s required pre‑replacement steps (model registration inspection, CAN/LAN re-scan, voltage and fuse verification, genuine-part verification, etc.) have been completed. I request ODI review because EyeSight should not fail to register unless hardware is defective or a procedural/voltage issue exists. I want this documented in case this represents a broader pattern of EyeSight registration/calibration failures on Forester models using the same stereo camera platform.

The eyesight system fails on almost a daily basis. When this happens, multiple safety features shutdown. Lane assist and departure warning stops working. Collision avoidance stops working. Cruise control stops working. Proximity warning alarms stop going off. The local dealership has repeatedly just indicated that this is how it works.

I was going down a highway using the lane keeping assistance feature. Suddenly the vehicle stopped following the road and ran me into a ditch. I was able to steer back onto the road, but if the ditch had been deeper I believe there would have been a rollover accident. The root cause is that when the audio system is turned up in the vehicle, the warning chimes do not interrupt the music or sound loudly enough to be heard over it. When the vehicle needs manual intervention assistance staying on the road, the driver may not hear the warning sound in time before the system disengages. The warning chime sounds need to be able to be heard over the audio system. This exact thing has happened to me 2-3 times in the last year.

While driving on I-17 Southbound near mile marker 311 at approximately 75 mph, I experienced a sudden and dangerous malfunction of the Lane Keep Assist (Auto-Steer) system in a 2021 Subaru Forester. The feature was active at the time and unexpectedly veered the vehicle sharply toward the concrete wall on the left shoulder of the highway. I attempted to regain control, but due to the abrupt nature of the malfunction, I overcorrected and collided with the wall on the rear driver side. There were no vehicles in the immediate vicinity, or this could have resulted in a multi-vehicle collision at high speed. I hit my head during the impact but did not require emergency medical services at the scene. Road conditions were dry and clear, with no visible debris or extreme weather factors. There were no warning lights or error messages from the vehicle prior to or during the incident. The Auto-Steer system did not disengage on its own before veering off course. This was the first time driving this particular vehicle, which was a company car, and I immediately reported the incident to my employer. The damage was reported and the vehicle is seemingly available for inspection. At the time of this report, the issue has not yet been formally diagnosed by a dealer or service technician. The failure of this driver-assist feature significantly endangered my safety and potentially the safety of others had there been nearby traffic. I am filing this report so the issue can be investigated, and similar malfunctions prevented in the future.

I got in my vehicle after getting gas. I was on my way to Neosho, MO, hundreds of miles from home. Thes lights were all on and I couldn't get them to go off. I figured it was because my windshield was dirty. I turned my wipers on to find out one needed replaced. I paid $30 for 1 since I have an odd type of wipers and I had been to 3 auto stores to find it. The Eye Sight, brake, check engine, air bag, and lane assist lights never went off. Now they come on randomly and go off randomly. This causes all safety features to not work. No adaptive cruise control, nothing. I finally got them to go off somehow the day I came back home. I live nowhere near a Subaru dealer. It had no other effect on my vehicle as far as I could tell. Now when they come on. I pull over until they come back on or have to drive it home to sit.

The check engine light and a flashing 'S' and other lights stating the safety features such as Eyesight, lane departure, RAB, etc. are turned off. This started on 1/15/25, and I took the car to the dealership on 1/16/25. The dealership stated the EVap System Leak Detection Pump sensor indicated a leak, and the EvaporateLeak Check Module needs to be replaced but is back-ordered until mid-March 2025. They turned off all the lights and told me I could keep driving the vehicle. On 1/20/25, all of the lights were back on. The car lags to accelerate and is using gas at a rapid rate. I feel unsafe driving the car for another two months with the check engine light on and the acceleration capacity decreased. The dealership will not allow me a rental vehicle unless I leave it on their lot for two months until the part arrives. I cannot agree with that. The dealership informed me that multiple Forester and Crosstreks models have the same problem. This car was purchased brand new from the Olympia dealership and it currently has about 22,000 miles on it.
