| Jul 2025 | STEERING,LANE DEPARTURE | 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. | Crash: Yes Fire: No Injuries: 1 Towed Medical attention | Unknown |
| Jun 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE | The Auto-Stop/Start feature frequently fails to properly restart the car, often causing the car to stall during the restarting process, leaving me effectively disabled on a busy road. The battery has already been replaced once. | Crash: No Fire: No | Unknown |
| Jun 2025 | VEHICLE SPEED CONTROL,UNKNOWN OR OTHER | I commute with my car and recently it started to speed up all by itself. I removed my floor covers thinking the gas pedal might be stuck on it but that wasnt the problem. While accelerating from a stopped position, it revs up and accelerates rapidly all by itself. Tapping the break pedal to deactivate accidendal cruise control doesnt work. I have to slam the break just to stop it from accelerating on its own. This is the fourth time it's happened. I have my personal mechanic change the oil every 3k miles and follows the factory recommendations on all other manufacturers recommendations. Very scary to drive because it happens at random. | Crash: No Fire: No | Unknown |
| Jun 2025 | ELECTRICAL SYSTEM | My vehicle is equipped with automatic start/stop system. In early 2024, I began having issues with sluggish restart during the start/stop cycle. I took it into the dealer at that time, who stated it required a software update and charged the battery. The issue persisted. It was more serious, as it was not just sluggish on the restart, but the restart would fail and stall the car. This happened in heavy traffic, which was very scary and unsafe. I took the vehicle back into the dealer in late 2024 for the same issue. They did another software update and charged the battery again. They recommended that we purchase a new battery. One month later, we purchased an upgraded AGM battery, as it was recommended for auto start/stop systems. The issue continued to persist. First, with sluggish restart. Later, the auto start/stop system failed again in heavy traffic. We took the vehicle in again, and again the dealer stated it was the battery. They recommended we purchase a new battery. It was explained the battery was 6 months old, and the issue has never been fixed. Further, it was pointed out that the car could be restarted manually with the push button ignition, after a start/stop system failure. That led us to believe it was not a battery failure, but a deeper system failure. The dealer continues to assert it is the battery, even though it happened with a factory battery and a new, upgraded, battery. Neither of the batteries have failed testing, and report as "good" on the diagnosis forms. We believe there is a system issue, that is causing issues with the auto start/stop system, and is not being identified by the dealer. It is a safety issue, as it has happened in heavy traffic several times. We have attached diagnostic reports from March 2024 and June 2025, but cannot find the October 2024 diagnostic report. | Crash: No Fire: No | Unknown |
| May 2025 | ELECTRICAL SYSTEM | Without any prior issue of having the engine turnover from being parked for more than 20 hours, the car would not start. It’s like the battery completely died overnight. I was able to unlock it but the car would not start, and therefore was unable to go into neutral because I didn’t have a long enough screwdriver with me to manually override into neutral. So it had to be jumped partially to be towed (had it towed for more than just the battery because it’s under warranty). The interesting part is that my car has a factory issued battery, and my car was the third Subaru made after 2020 that had to be towed due to the same issue, in the same day. Maybe the batteries are defective? Regardless, since everything relies on power now, having a provided device to allow for manual override would prevent folks from being stranded. I tried using my key AND the screwdriver that comes with the spare tire. Both were to short. | Crash: No Fire: No | Unknown |
| May 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE | The automatic shutoff that occurs when the vehicle stops to prevent idling, disengaged two separate times in the span of 4 days. Both incidents occurred at very busy intersections and failed to restart both times. When attempting to restart the car, lights came up on the dash, along with beeping, and failed to restart the car after the light had turned green. To restart, the car had to be completely turned off for about 60 seconds and then could be restarted. To avoid having to experience this issue again, or worse - get into an accident - I took it to the shop where they could not recreate the issue. | Crash: No Fire: No | Unknown |
| May 2025 | UNKNOWN OR OTHER | Automatic stop activated at traffic light. When the brake was disengaged, the star would not start. The occupant was stalled at the traffic light during rush hour in a thunderstorm with limited visibility for approximately 15 minutes. Winter Haven Police Department was dispatched but did not arrive probably due to other weather-related traffic situations. After that time, the engine did start and was moved into a lot without incident. The good Samaritan that assisted stated he had just stopped down the street on another disabled vehicle in traffic due to malfunctioning auto stop/start. Here is the issue. The alternator and battery have both been checked twice and were in proper order. The OE battery was in use. There was no warning to indicate any issue with the batter. In fact, the Subaru app was reporting the vehicle was operating normally while the vehicle was dead in the road. I work with a local law enforcement agency and have worked fatal crashes on that road. It is unacceptable for the vehicle to not have some type of redundant system to warn owners that the vehicle battery is failing before they are thrust into a possible deadly roadway breakdown. | Crash: No Fire: No | Unknown |
| May 2025 | ENGINE | 2021 Subaru forester limited- Stop Start when stopping at a red light. Sometimes the engine does not restart when releasing the brake pedal. Message on dash put car in park and press start. Occurred. April 24 2025 and May 5 2025 | Crash: No Fire: No | Unknown |
| Apr 2025 | ENGINE,FORWARD COLLISION AVOIDANCE | Was stopped at traffic light. Start Stop system was engaged. Engine turned off as normal. When I took my foot off the brake the engine did not engage and the Eyesight warning light came on that the Eyesight system was not functioning. Put the car in park and engaged the ignition button and the engine started. Turned off the Start Stop system and the car functioned normally after that. Have read postings on Subaru forum that this has happened to others. | Crash: No Fire: No | Unknown |
| Apr 2025 | VEHICLE SPEED CONTROL | The contact owned a 2021 Subaru Forester. The contact stated that his wife attempted to turn into a parking lot while her foot depressed on the brake pedal, the vehicle jolted into acceleration, ultimately crashing into two parked vehicles at 5 MPH. The front passenger side of the contact's vehicle crashed into the front of two vehicles. No property damage was reported. The vehicle came to a stop upon impact. The air bags did not deploy. The vehicle was not towed. The Steering Responsive Headlight Warning Light was illuminated. A police report was filed. The vehicle was destroyed. No Injuries were reported. The local dealer was not contacted, and the vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 39,500. | Crash: Yes Fire: No | 39,500 |
| Feb 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | My dealer diagnosed issues with my car as: the gasket around my sunroof failed and allowed water to infiltrate the cabin and the electrical system over time. This caused corrosion in the electrical harness, which caused battery failure, failure of the adaptive headlight system, and random electrical glitches. My interpretation of their diagnosis was that this was a cascading failure that might have led to problems with other electrical components such as power brakes, other adaptive systems, etc., and affected safety, if it had not been diagnosed in time. An insurance appraiser confirmed the dealer's diagnosis. Repairs (including replacing the electrical harness) have been completed and so the situation is not available for further inspection. When the adaptive headlight system stopped working, this was reported on the dashboard, but the cause of this and the base problem was not. | Crash: No Fire: No | Unknown |
| Feb 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,SERVICE BRAKES | 1. The car shut off several times, with the steering wheel locking up and becoming stiff, the brakes failing to respond, and loud, erratic sounds emanating from the vehicle. The car is available for inspection. 2. Yes, the car crashed resulting in damage to the car, driver, and other driver (e.g. car in front). 3. This is the second time the car has been brought to the dealership (the second time being Subaru South Hill in Pennsylvania) and they cannot identify the problem. 4. The vehicle was not inspected by police, or insurance, as far as I am aware. 5. There were no warning signs before the failure. | Crash: Yes Fire: No Injuries: 1 Towed Medical attention | Unknown |
| Jan 2025 | UNKNOWN OR OTHER | In the summer of 2024, my forester started completely stall out when I was stopped at a stop light. The auto start/stop system seemed to not turn back on. I would have to put the car in park, turn the car off and turn it back on. It was very scary being in traffic and people getting upset behind me. This happened multiple times. I took my car to the dealership. I was told an update needed to be installed and it was not anything I could do at home. After that point, it worked better, but still started back up hard at times. When I remembered, I typically started turning the feature off each time I drove it because I do not trust the feature. Unfortunately, it happened again yesterday. We were at a stoplight, and the car did not start back up, it stalled out. My husband had to quickly try to put the car in park, turn it off and then back on. Cars started honking at us. I am very concerned about this feature. | Crash: No Fire: No | Unknown |
| Jan 2025 | ELECTRICAL SYSTEM | MY 2021 Subaru Forester battery has died twice in the last 10 months. I could not jump start the vehicle the first time about 10 months ago. I needed AAA to jump start it. I took the car to the dealer; they recharged the vehicle and said the battery was fine. They did not bill me. The car died again this week. This time I was able to jump start the vehicle myself. The safety issue is I might need to get to a doctor's appointment or other emergency in a hurry. I may be out shopping or hiking and need to return home, perhaps in bad weather. I might be stranded in a busy intersection or a lonely country road. The battery is simply not trust-worthy. The vehicle was inspected by the dealer, and they said the battery was fine. There was no warning lamp before the battery failed. The car is not safe-I don't know when it won't work. | Crash: No Fire: No | Unknown |
| Jan 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE | 12/14/24-I was stopped at a red light at a VERY busy intersection. The engine was in stop mode by the start/stop feature. When the light turned green, the car failed to start. The entire car shut down, with alarms sounding and dash lights flashing. The entire system had to reboot before I could restart the car. It was a freighting experience. Fortunately, I wasn't killed by traffic zooming by or by some person with road rage. 12/16/24-Issue evaluated by local Subaru dealer. Their evaluation was that when the auto start feature was activated, my car battery was too low to work. There was zero warning about a low battery before this failure in traffic. I had to buy a new battery. The auto start/stop feature is not an enhancement, but a safety hazard. Owners should be able to permanently disable this unnecessary drain on batteries and starters. I did a search, and there are plenty of others that experienced similar issues with their Subarus. | Crash: No Fire: No | Unknown |
| Jan 2025 | POWER TRAIN,ENGINE | At 40936 the valve body needed to be replaced. With such low milage vehicle is having problems. | Crash: No Fire: No | Unknown |
| Nov 2024 | POWER TRAIN,VISIBILITY/WIPER | Having repeat issues with the windshield cracking. My vehicle has around 32k miles, and I'm already on my 3rd windshield. I've never had this issue with any other vehicle. It's been extremely costly. Also the transmission failed and had to be replaced at 26,000 miles. | Crash: No Fire: No | Unknown |
| Oct 2024 | VISIBILITY/WIPER | The front windshield is covered in chips all over it I've got a few bigger ones repaired. However the whole windshield needs to be replaced I don't even know where they've come from I mean the whole windshield is just covered and tiny little chips and when the sun shines on it while you're driving It makes visibility extremely hard. And from what I gather researching windshields on Subaru this is a flaw... I've had plenty of vehicles and never have seen such a bad windshield. I recently purchased this vehicle in August and it has $112,000 mi on it. I did not see the issue with the windshield until after purchasing it and driving in direct sunlight. I did notice a few big chips in The windshield and the dealership did repair those... | Crash: No Fire: No | Unknown |
| Oct 2024 | ELECTRICAL SYSTEM | The contact owns a 2021 Subaru Forester. The contact stated that while waiting at a traffic light, the accelerator pedal was depressed, and the vehicle immediately shut off. During the failure, the message "Eyesight Disabled" was displayed and the vehicle could not immediately be restarted. The gear shifter was shifted to neutral(N) and the vehicle was pushed to the side of the roadway. The vehicle was eventually restarted and operated normally. The cause of the failure was not yet determined. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was 37,000. The VIN was not available. | Crash: No Fire: No | 37,000 |
| Sep 2024 | VISIBILITY/WIPER,LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | **Component Malfunction**: The windshield developed cracks shortly after purchase, which expanded without impact, affecting visibility and causing the Safety Eyesight system to malfunction. **Safety Risk**: The expanding crack impaired vision and led to safety system malfunctions, posing a risk to driver and passenger safety. **Problem Reproduction**: It is unclear if the issue has been reproduced or confirmed by a dealer or service center. **Inspection Status**: The vehicle has not been inspected by the manufacturer, police, or insurance representatives. **Warning Signs**: There were no warning lamps or messages prior to the failure; the issue appeared in the first week after purchase. | Crash: No Fire: No | Unknown |
| Aug 2024 | STRUCTURE | While driving on the highway on 8/15/24, the rear driver's side door randomly opened. The warning/indicator light came on, as well as the overhead lights. I also immediately was able to hear extra road noise coming from that side and could clearly see through my side view mirror that the door was ajar (it was not wide open). I have not had the car inspected by anyone. | Crash: No Fire: No | Unknown |
