| Nov 2024 | 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 | **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 |

| Jul 2024 | UNKNOWN OR OTHER | I’ve owned the vehicle under a year and am already on my second window replacement. I drive the same route everyday and ever experienced windows cracking in any other vehicle before this vehicle. | Crash: No Fire: No | Unknown |
| Jun 2024 | ENGINE | Thermo control valve defective. Not informed one week ago when I purchased car at end of lease. Problem known to Subaru since 2019 or sooner. Would not have purchased if I had been notified about this major problem | Crash: No Fire: No | Unknown |
| Jun 2024 | VISIBILITY/WIPER | I was driving along the highway when I heard the sound of a pebble hitting my windshield. When I got home, I immediately checked my windshield and did not see any damage. I was quite relieved. Two hours later, I looked out and saw a very long crack had appeared. The crack went from nothing to about 22 inches long in a matter of hours. I went to investigate further and saw that the pebble created a small pit on the edge of the windshield. Unfortunately, like typical windshields, the pit did not remain consistent in size and stay put. Instead, it spread out as a very large crack on the window. I read today that Subaru has a lawsuit against this very thing - faulty windshields. I have had this vehicle two weeks and now have a very costly repair because of the eyesight technology. I bought this car for its reliability without knowing that it had faulty windshields. | Crash: No Fire: No | Unknown |
| May 2024 | VISIBILITY | The contact owns a 2021 Subaru Forester. The contact stated that while driving at an undisclosed speed, the front windshield cracked without impact. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 34,350. | Crash: No Fire: No | 34,350 |
| May 2024 | UNKNOWN OR OTHER | To whom this may concern, My name is [XXX] . I was the owner of a 2021 Subaru Forester. I bought this car brand new and I loved this car. One of the biggest reasons I bought a Subaru is because of the multiple safety features the car has. I've had this car for three years and always felt safe until last week. During a road trip on [XXX] at [XXX] My car hit a deer on the front drivers side and within seconds caught on fire. The entire car was engulfed in flames within 3 minutes. All passengers were unharmed and we were able to get 95% of our stuff out of the car. This experience was pretty traumatic knowing that I was supposed to be driving the safest car in America and it caught on fire very easily from a baby deer hit. Not only did my car catch on fire but it left us stranded in the middle of Utah. Thank god it was in a big enough town that had a car rental. Insurance is still assessing my car and I'm currently in the market for a new car but with everything that happened it makes me feel very uneasy about getting another Subaru.

| Apr 2024 | VISIBILITY/WIPER | Just discovered this morning that the windshield of my car has a long crack without being hit by any item like stone or small debris. It also affects the eyesight as it malfunctions occassionally | Crash: No Fire: No | Unknown |
| Apr 2024 | VISIBILITY | The contact owns a 2021 Subaru Forester. The contact stated while driving at an undisclosed speed, she observed micro-fractures developing on the front windshield of the vehicle. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 15,000. | Crash: No Fire: No | 15,000 |
| Apr 2024 | VISIBILITY/WIPER | Windshield has cracked twice with no visual impact site or minimal impact. Occurred almost ‘spontaneously.’ Both incidents had significant splintering on the windshield impairing visibility. Incidents occurred within 6 months of each other. The windshield cracking can also affect the ‘Eye Sight’ camera with the car safety features. Appears to be a known issue with the type of glass used. | Crash: No Fire: No | Unknown |
| Feb 2024 | ENGINE,FUEL/PROPULSION SYSTEM | Vehicle was parked and idling unoccupied for under 5 minutes when an extremely noxious, hot blast of fumes came from underneath the back. Black smoke immediately entered the passenger cabin through the vents and flames were visible in the engine compartment and running onto the ground. Entire vehicle was burned beyond recognition in a matter of minutes. Ten days earlier the TCV, a known problem, had been replaced at a dealership per TSB 09-80-21. The vehicle had been driven under 300 miles since the replacement. Afterwards, a manufacturer rep inspected the vehicle, indicated the fire started in right rear of the engine compartment, could have possibly been a fuel leak, but damage was too extensive to determine the exact cause. The referenced TSB explicitly requires a new fuel line for every TCV replacement. | Crash: No Fire: Yes | Unknown |
| Feb 2024 | POWER TRAIN,VEHICLE SPEED CONTROL,ENGINE | The 2021 Subaru Forester had been functioning normally with no warning lights. About 25 minutes into the drive I had come to a stop light on an upward incline. When the light turned green I moved from the brake to the gas as usual. However the auto-start function on the car failed, causing the engine to stall. A loud clunking sound was heard and the dashboard lit up with multiple lights, although I do no recall which ones were illumined. I attempted to press the gas again and the car did not respond. During this short time my foot was pressing on the gas the car rolled backwards and collided with the vehicle behind me. I continued attempting to press the gas pedal and still no acceleration was made. After parking and restarting the car it has resumed normal function. I have not yet visited the dealership so this issue has not yet been reproduced, nor has the offending system been inspected. I'm summary, the automatic engine start failed at a critical location, putting myself and others in serious danger and ultimately caused a crash. | Crash: Yes Fire: No | Unknown |
| Feb 2024 | ELECTRICAL SYSTEM | The automatic shut off feature causes the car to lose all power. No power at all in the middle of traffic and I can't even use hazard lights to warn anyone. When at a stop the auto shut off turns off the car and when I take my foot off the brake it completely dies. It has happened 5 times in the last 3 days. Very dangerous. Imagine this happening on the freeway during rush hour. It's a miracle if no one has been killed. I saw countless posts from others on different forums. I have only owned this car for a week and half, taking it to the dealer today. This needs to be a recall paid for by Subaru, it is unacceptable. | Crash: No Fire: No | Unknown |
| Feb 2024 | VISIBILITY/WIPER | Had a rock barely touch my windshield causing a crack | Crash: No Fire: No | Unknown |
| Feb 2024 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | Once or twice a day my vehicle hesitates from a light and I have to almost floor it to get it going again.I have brought it to 2 different Subaru dealers 3 times and they say they can't fix the problem. | Crash: No Fire: No | Unknown |
| Jan 2024 | UNKNOWN OR OTHER | My vehicle starlink infotainment system does not work. This is a safety hazard because it prevents drivers from using their back up cameras and this car has many blind spots. This also frustrates drivers and causes distraction as navigation is not available. The screen display abruptly stopped working. I brought my vehicle to the dealer and their solution was to spend $1700 on a new infotainment system. Owners should not have to be paying to utilize safety features marketed for the vehicle they bought. There were no warnings prior to the system breaking. | Crash: No Fire: No | Unknown |
| Jan 2024 | UNKNOWN OR OTHER | My Forester was parked and when I started the car I heard a pop, pop, pop. Looked at my front windshield and watched it crack from the lower left - driver side - up to the center of window, with each pop. Googled - the community has posted similar problems with Subaru windshields. Temperature on [XXX] in Phoenix was 60 degrees at the time of windshield popping. No impact, parked car, started engine and crack just started and I watched it expand from 2 inches to 24". Very scary!

| Jan 2024 | POWER TRAIN | Thermo control valve failed at about 42000 miles on 2021 Subaru Forester Premium, on 1/1/24. Owned 3 yrs 1 mo. Car was parked at work. Immediately after car was started up for return commute -- check engine light was on, ADAS systems ("Eyesight") disabled, blue low coolant temperature light on, and no heat through HVAC. Fortunately car driveable, despite safety being compromised with disabling of the safety features (blind spot monitor, rear cross traffic alert) and concern about damaging engine being forced to drive home with check engine light on. Engine failed to warm despite 40+ min highway trip. As this was commute vehicle, forced to take next day off work to have check engine light looked at. The next morning windshield ice had to be manually scraped (no heat). Drove car gingerly to dealership (<10 mins) avoiding freeways, for fear of damaging engine. Unknown if windshield defroster would've worked if started fogging mid-trip (safety concern). Dealership inspected vehicle - diagnosed thermo control valve failure, and replaced part. I was not charged as the car was still covered under powertrain warranty. No warning prior to the failure. Drove normally on the morning drive to work. Dealership replaced TCV with a part that has the same part number, per Subaru's TSB. Given experience of others indicating high failure rates of TCV after 3-4 years, and what I suspect is genuine design defect, I expect replacing the part to only have temporarily reset the clock -- seems certain to fail again. I have no confidence that Subaru has implemented an actual solution. I do not know if the next failure of this powertrain component will happen under warranty, or if it will incur signficant out of pocket costs (well over >$1000 to replace). Furthermore, if TCV fails whilst driving (as could have happened, and has been reported by others elsewhere), this will be a safety hazard with sudden disabling of blind spot monitor / rear cross traffic alert. | Crash: No Fire: No | Unknown |
