| Date | Component | Summary | Severity | Mileage |
|---|---|---|---|---|
| Sep 2023 | VISIBILITY/WIPER | Was driving at highway speeds (65 mph) and within the posted speed limit and a small, unidentifiably small object was kicked up by a car in the adjacent lane and hit the windshield, resulting in a small ding that immediately spread to a large crack across most of the windshield. | Crash: No Fire: No | Unknown |
| Sep 2023 | VISIBILITY | The contact owns a 2020 Subaru Forester. The contact stated that the windshield was cracked. The crack had developed on the passenger’s side of the windshield’s edge where the windshield meets the frame and expanded 6 inches horizontally. The contact had not taken the vehicle to the local dealer or the glass shop. The windshield was not replaced. The manufacturer had not been informed of the failure. The failure mileage was 8,978. | Crash: No Fire: No | 8,978 |
| Aug 2023 | POWER TRAIN | The thermo control valve malfunctioned causing the check engine light to come on which shut down all the safety features in the vehicle including the front eye sight camera, blind spot warning, the rear automatic braking, lane departure warning, adaptive cruise control, and lane keeping assistance. The check engine computer readout diagnostic trouble code was P26A5 "Engine Coolant Bypass Valve "A" Position Sensor Circuit Range/Performance". The vehicle was taken to a Subaru dealer who found the thermo valve performance was out of spec. The valve was replaced. This vehicle has not been recalled although the manufacturer replaced the part in 2021 vehicles acknowledging the valve was faulty. Because of the mileage on my vehicle, it was not covered under the warranty although many have been replaced under the manufacturer's warranty due to the failure of this valve under the 60,000 mile warranty. Through a "Goodwill gesture" Subaru replaced the part in my car at no cost. I believe this should be a recall item for others who experience this issue. | Crash: No Fire: No | Unknown |
| Aug 2023 | UNKNOWN OR OTHER | Windshield cracked for no apparent reason. | Crash: No Fire: No | Unknown |
| Aug 2023 | VISIBILITY/WIPER | The windshield suddenly crack for no apparent reason. I inquire about this problem from the Subaru service department and I was told that its not covered by warranty. I found out from my own research that a lot of Forester owner have complain of the same issue. | Crash: No Fire: No | Unknown |
| Jul 2023 | POWER TRAIN,LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | While driving, the 2020 Forester, the check engine light, collision light, eyesight function lights all went on at the same time. I brought vehicle to check diagnostics and it is showing Engine Coolant Bypass Valve "A" Control Circuit low in Power Train System. Their were no messages prior to all the lights turning on and I was able to bring into the dealer for oil change but not able to make an appointment for repair for a few days from now | Crash: No Fire: No | Unknown |
| Jul 2023 | VISIBILITY/WIPER | For the 3rd time in less than 3 years my windshield crack from a small pebble hitting it. Either Subaru is making very thin windshield glass, or the material used is not sufficient to suppress small pebbles and causes the windshield to crack, often. The latest crack happened July 25, 2023 in the PM with a small 1/4 inch crack, by morning it had grown to over 2 feet. It seems to me there is a design flaw here. | Crash: No Fire: No | Unknown |
| Jul 2023 | ENGINE | While driving on the highway, the engine suddenly stopped and several warning lights appeared on dash. Driver was able to coast to shoulder but could have been a bad accident. It happened again on the way to dealer service center. Dealer reproduced the problem and identified it as a faulty thermo control valve. Dealer fixed it under warranty. Review of web reports makes this seem like a common problem with various Subaru automobiles. | Crash: No Fire: No | Unknown |
| Jul 2023 | VISIBILITY | The contact owns a 2020 Subaru Forester. The contact stated that there was a chip on the front windshield that was not caused by an impact. The front windshield was cracked. The contact called the local dealer and was referred to an auto glass shop. The vehicle was taken to the auto glass shop that replaced the front windshield, but the failure recurred. The contact stated that while her son was occupying the vehicle, he noticed that the front windshield was cracked. The vehicle was not repaired. The manufacturer was contacted. The failure mileage was 25,000. | Crash: No Fire: No | 25,000 |
| Jul 2023 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | Error code (P26A3?)for - Engine Coolant Bypass Valve. Causes the "Check Engine" light to come on and automatically disables ALL of the safety and collision mitigation systems. The Engine Coolant Bypass Valve failure is common and a known issue and Subaru has already updated the part on newer vehicle models. The common failure of the coolant bypass valve should not be disabling the safety features and the collision avoidance systems. | Crash: No Fire: No | Unknown |
| Jul 2023 | ENGINE AND ENGINE COOLING,ENGINE | The contact owns a 2020 Subaru Forester. The contact stated that while driving approximately 70 MPH, the accelerator pedal was depressed, and the vehicle started to lose motive power. The check engine warning light was illuminated. The vehicle was steered to the side of the road where the vehicle then stalled. The vehicle was restarted approximately 15 minutes later. The vehicle was towed to a dealer where it was diagnosed that the thermal control valve and electric water pump needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 13,000. | Crash: No Fire: No Towed | 13,000 |
| Jul 2023 | POWER TRAIN,FORWARD COLLISION AVOIDANCE | I was driving on a paved two lane rural route and hit a small bump in the road. Immediately, my check engine light came on and all the safety features turned off. Control panel showed multiple safety features off and the Sport mode indicator light blinking. My car only has 17K miles on it and I have had it just over a month. I was able to drive it safely home and when I called the dealership the next morning I was told I could continue to drive it until the service appointment six days later. When I got home, my husband checked it with his CEL reader and got the code for the temperature control valve (an issue known by Subaru). This was confirmed by the dealership and I was told after having driven it for several days that it should not be driven. The repair is being covered under the power train warranty. | Crash: No Fire: No | Unknown |
| Jul 2023 | POWER TRAIN,VEHICLE SPEED CONTROL,FUEL/PROPULSION SYSTEM | Our thermo control valve (TCV) assembly failed and caused dangerous loss of speed and control while on the highway. Subaru is fully aware of the defect in their design as they issued a service bulletin to inform their service centers of a new, fixed TCV assembly that is retaining the same part number (a notice only sent to their service centers, NOT to owners). Please see attached. Despite being aware of the defect, Subaru has not voluntarily replaced the defective TCV assemblies or even bothered to notify owners. Instead, they are letting us put our families and other drivers in dangerous situations through sudden loss of control. There are pages and pages of other owners experiencing this dangerous issue and - like me - being surprised to find it's a known issue that Subaru is not proactively fixing (see any of the owner forums like subaruforester.org). | Crash: No Fire: No | Unknown |
| Jul 2023 | Chest Clip, Buckle, Harness | My one year old is able to press the chest clip and it unlatches. So now the only thing holding him is the buckle. He has been able to undo the chest clip. While driving in traffic. This should not happen. Could be terrible danger if got in a car accident. | Crash: No Fire: No | Unknown |
| Jun 2023 | VISIBILITY/WIPER | Windshield randomly cracked while parked. There was no hit to the windshield that was detected. Crack runs down middle of windshield. | Crash: No Fire: No | Unknown |
| Jun 2023 | VISIBILITY/WIPER | (06/22) - Small pebble hits windshield and creates a "star-pattern" crack measuring 2.25 inches in diameter. Booked earliest appointment for windshield replacement on Tuesday 06/27. Have not touched windshield and have not driven vehicle as of this day. (06/24) - Waiting for windshield replacement appointment; star-pattern crack has extended aggressively overnight while parked under shaded carport (average temp 64 degrees), far beyond what is typical. As of 06/24 there are 2 long cracks extending in opposite directions measuring 9 inches above and 13 inches below original impact diameter. Please note that Subaru has had prior class action lawsuits filed for similar issues regarding brittle/unsafe windshields for Subaru Outback and Forester 2016-2020 models. | Crash: No Fire: No | Unknown |
| Jun 2023 | ENGINE | While driving on an Interstate highway the engine suddenly lost power and various warning lights lit up on the dash, including brake, eyesight, RAB. Managed to limp to the shoulder without getting hit and had the car towed to the dealer, who replaced the thermo control valve assembly under warranty. | Crash: No Fire: No | Unknown |
| Jun 2023 | UNKNOWN OR OTHER | My wife was out this morning meeting friends for coffee. She gave a friend a ride home and she noticed a crack in the windshield on the drivers side. There was no indication that it was hit with a rock or anything else. I see that there was a lawsuit against Subaru for defective windshields. | Crash: No Fire: No | Unknown |
| Jun 2023 | POWER TRAIN | The thermo-valve controller gives out on this vehicle. Through searches and discussions with two separate dealerships, this seems to be an incredibly common issue. It's enough that Subaru has actually completely replaced the design of this piece for whenever it gets replaced. This triggers a check engine light which already removes many features on the Subaru. My understanding is that this part controls and measures the engine temperature which means that drivers have no clue if their engine is overheating or not when it goes out. Subaru has gotten away with covering this part over their Powertrain warranty since the vast majority of their vehicles are having this part break within 3 years. Most drivers are happy with this because the major ($1500-2000) repair is covered. The issue is that people that drive more often, like myself, are stuck footing the bill for a part that Subaru has admitted doesn't work properly just because we've now fallen out of this 60k mileage warranty. From my research, it's not a part that is greatly affected by mileage, so much as time since the dealerships have noted that every replacement they've seen has fallen within 3 years, regardless of the mileage. For that, I'm asking that there be a true recall put in place for this part. This is a major expense for almost anyone and isn't fair for Subaru to hide behind a warranty that won't apply to everyone when they know they created this improperly. Even the reps at the dealership mentioned that they see this far too often for it not to be a recall, but that most people are still under 60k miles, so there aren't normally issues. | Crash: No Fire: No | Unknown |
| Jun 2023 | VISIBILITY | The contact owns a 2020 Subaru Forester. The contact stated while driving approximately 2 MPH down her driveway, she heard an abnormal popping sound coming from the dashboard. The contact observed that a crack had appeared in the center of her windshield that formed at the bottom of the windshield. The contact stated that the crack extended more to the passenger’s side of the windshield. The contact called the local dealer and was advised by the dealer to contact the insurance provider for assistance. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 50,000. | Crash: No Fire: No | 50,000 |
| Jun 2023 | AIR BAGS,UNKNOWN OR OTHER,ENGINE | Thermo control valve needed replaced. Check engine light and all safety lights turned on. All safety features were disabled when light came on. Subaru has has a recall on 2019 but not 2020 . | Crash: No Fire: No | Unknown |
| Jun 2023 | VISIBILITY/WIPER | While driving, I heard a loud POP. I thought something hit the car, but I was not close behind another vehicle or road hazard. For about 15 minutes I thought no harm, no foul. Then suddenly, I saw a long, mostly horizontal crack from the bottom left and extending about 18" toward the center of the windshield. I called the Subaru dealer [where I bought the car] and was quoted $910 parts and $590 labor, but they were unable to give me a service appointment date at that time. I don't feel the car is safe to drive, so I am looking for a quicker repair from an independent windshield replacement shop. At the same time, I researched Subaru windshield cracks and found numerous reports of easily cracking Subaru windshields. It appears that if I replace one Subaru windshield with another Subaru windshield, I may just be waiting for another Subaru windshield crack in the future. | Crash: No Fire: No | Unknown |
| Jun 2023 | VISIBILITY/WIPER | Windshield cracked in the bottom black area. This is a known problem for other model years. Subaru should issue a recall / fix for the 2020 Forester also. | Crash: No Fire: No | Unknown |
| Jun 2023 | ELECTRICAL SYSTEM,ENGINE,FORWARD COLLISION AVOIDANCE | The thermo control valve on my 2020 Subaru Forester is broken and needs to be replaced. I have owned the car for 2 years, am the first owner, and it has less than 19,000 miles. 90 minutes into a drive the "coolant temp low" indicator light came on. After I pulled over, turned off the engine, and turned it back on the check engine light and sport mode indicator light came on, and all ADAS were disabled. The coolant level was low so I refilled it and took it to the manufacturer the next morning. They inspected my car and confirmed it the thermo control valve was broken. It is still broken as I cannot afford the repair and it is available for inspection upon request. My safety was put at risk by not having access to the ADAS forward collision warning, emergency breaking, and lane departure. | Crash: No Fire: No | Unknown |
| May 2023 | ELECTRICAL SYSTEM | This vehicle has approx. 45,000 miles and the electrical has failed. We have replaced the battery and tested all components in which they then operate fine. However overnight the battery fully drains, leaving us with no vehicle again. This vehicle has no accidents, maintained every 3 months and the health report even shows no issues/errors. No other symptoms have been noted. this car works and runs 100% like it did day 1 up until 3 days ago. Where it has died overnight every day. Luckily my husband is a mechanic as he indicated the last instance of a new battery going in, the dashboard was flashing and going haywire to the point that it wouldnt stop until he removed the battery. He indicated that its likely this would have been an electrical fire if the battery was not removed therefore could have caught on fire with myself and our 14 month old inside. There were no warnings, no alerts, no vehcile safety alerts, the mysubaru app in fact still says we have a 100% healthy vehicle. | Crash: No Fire: No | Unknown |
