The electrical system fails, and the battery is not charging sufficiently. When the auto start/stop engages, the car does not restart in traffic. Requested a battery test at the dealership in May 2025; was told it could not be done that day because it would require leaving the dealer service shop. Eventually, the electrical system became unstable, and the car stopped in traffic on 11/07/2025. Replaced battery following OEM specs. In February 2026, symptoms reappeared with a new battery failing on 02/15/2026, resulting in all saftey systems failing in traffic when auto start/stop enages.

While at a Stop as the engine turns off and awaits decompression of brake to turn on again vehicle moves forward bit, then the engine shuts down while in drive (stalls) had a vehicle hit me in rear but luckily I had my trailer hitch on because it saved me from body damage . I had to place in park and restart this has happened several times before and I’m kinda nervous and makes my wife nervous when stopping at lights or stop signs it might turn off in the middle of the intersection. When this occurrence happens all dash lights pop up … I checked engine with code reader after the incidents but it doesn’t give out any info on what could possibly be happening. I had the Dealership change the Thermo control module in 2025 but these occurrences has happened before and after the TCM replacement.Having the dealership check is like wasting my time and money because they aren’t able to pinpoint the cause without a code . There has to be a problem somewhere in the system it’s just that the dealership in Hawaii has no clue ..

- *Incident 1 (2023):* While driving, my vehicle suddenly stopped while in drive gear, accompanied by a high-pitched alarm and multiple engine service lights. It took over 30 seconds to shift into park and restart the vehicle. The incident occurred at an intersection, and I was fortunate to avoid any collisions. - *Incident 2 (September 2025):* The same problem recurred on two separate occasions- AFTER CERTIFIED REPAIRS. The vehicle came to a complete stop while driving uphill at a decelerated speed, and also while stopped at an intersection. In both instances, the gear was in drive, and the vehicle shut down completely, displaying engine service lights. *Previous Repairs:* - *TCV Replacement:* The Thermo Control Valve was replaced under warranty due to a faulty issue affecting the EyeSight system. - *Battery Replacement:* The battery was replaced under warranty in 2023 after the initial incident. Whats concerning is that my dealer said to have found an “after market” appliance hooked up. This said feature was placed by certified subaru dealership when vehicle was purchased. This said item was never identified as to causing the said issue. Which raised even more safety concerns.

50k Mileage Mark: When the vehicle turned off at the stop light to save gas, the car stalled. I had to frequently put the car back in Park, and restart the engine. Since then, I had to turn off the “auto turn off” function for fear of the car stalling on the road. This has caused unnecessary anxiety and fear while driving, harming my psychological wellness. Since the 50k mark this has happened about 10 times. The most recent issue was this month

CVT Transmission failed and not repairable. 6 months out of warranty but under mileage for warranty at 37,000 miles. Fairly new vehicle that is useless w/o $9,000 for a replacement transmission. Exact same defect in 2018 and older models that Subaru is covering repairs and extended warranty for those years.

On April 16, 2024 the Thermo Control Valve on my 2019 Subaru Forester failed while I was going 70 mph in the middle lane of rush hour traffic. All of the warning lights came on at once as my engine stalled. I lost all mechanical power and was barely able to make it off the highway without getting hit. There was no prior warning that the Thermo Control Valve was bad. I had the car serviced at a Subaru dealership three weeks before the incident and was told that everything looked good on my car. The dealership replaced the Thermo Control Valve under extended warranty coverage. I have a second 2019 Subaru Forester that also falls in this group of vehicles, but Subaru will not replace the Thermo Control Valve until it fails.

While driving on a highway outside Milford, CT my vehicle is check engine light suddenly illuminated. I had a sudden loss of power, no heat, and the engine temperature was unable to read. Engine temperature was not accurately reporting and showed it as being cold as indicated by blue light warmup light. My eyesight, pre-collision system, and sport mode was disabled due to the engine light being illuminated. The vehicle was seen at a Subaru dealer, who diagnosed the issue to be the thermo control valve. Dealership informed me that it was unsafe to drive and I risk complete engine failure, overheating, and or fire if I continue to operate without required repair. As a result, I was stranded overnight, three hours away from home. Repair was completed on [XXX] at cost of $1830. I learned at the dealership that this is a known issue, in 2021 Subaru replace the plastic components of this part with aluminum due to similar issues experience by many customers. Customers are reporting vehicles going into “limp mode” and even engine damage. I learn that there is a class action lawsuit regarding the same issue, which can be reviewed here: [XXX] Please help to recall vehicles and push Subaru to repair/refund.

Defective/failed thermal control valve. Valve failed while I was driving, resulting in safety systems (e.g., lane keep assist, pre-collision braking). Looking this up, this is a known issue to Subaru.

When driving, ALL lights on the dash went on and vehicle safety features did not work- no cruise control, automatic breaking, automatic headlight adjustments, etc. We were over 500 miles from home and had the oil changed but it did not fix the problem. Had $72,000 miles on it, 4 years old. We had to drive home that distance to get it repaired over a 2-3 day period. No safety features were enabled as we drove. Thermo Control Valve was deemed faulty and replaced. Seeing after the fact that the TSB was issued without any VIN numbers: [XXX] , I believe it should include our VIN number and be recalled and the replacement paid for.

My wife was driving her 2019 Subaru Forester (purchased new) and the Eyesight disabled and the check engine light came on. The car was still running, but not as it normally would. It had less power but would still maintain the speed limit. At home the car idled differently, like it was running too rich or too lean. The exhaust also smelled funny.
Power train, Forward collision avoidance, Jun 23, 2023
Was driving in the right-hand lane on the interstate with the cruise control set, went to change lanes as I was approaching a slower moving semi truck going up an incline. Cruise control deactivated with no inputs from myself. Vehicle began to decelerate. Looked at instrument cluster, the Check Engine Light was on along with Eye Sight Off symbol. Additional symbols for forward collision avoidance and rear active braking were also on. No warning signs were present prior to the cruise control turning off. The unexpected loss of power increases the risk of collision while traveling on the highway. Vehicle was taken a Subaru dealer, diagnosed with code P2682, Coolant Bypass valve performance, with a recommendation to replace the coolant bypass valve.

On June 20, 2023, the "check engine" light came on my 2019 Subaru Forester and "Eyesight" flashed on my dashboard as disabled. I immediately went to my mechanic and he ran a diagnostic which showed the following: "P26A3 - Engine Coolant Bypass Valve." My car has 75,000 miles and is out of warranty for the powertrain. In reviewing online forums, this problem is a recurring one that is affecting many Subaru owners. The cost is $1,200 to $1,500 to fix. I believe this should be a recall issue. Other drivers have noted sudden engine shutoff but I have not experienced that yet. The car is currently in the shop. Subaru knows this is a problem.

On January 1, my wife was returning home from a grocery run when our 2019 Forester’s dashboard suddenly lit up like a Christmas tree--Check Engine, EyeSight, Anti-Lock Brakes, Anti-Skid, and blue Temperature lights all came on simultaneously. The Forester did not lose any appreciable power but the heater stopped working and was only blowing cold air. My wife was only a couple of miles away and brought it straight home. I checked under the hood but had no idea what was going on, so I drove it over to my local Autozone for a scan, and it came back with the 'P26A3' Code, as well as 'P3300,' and 'P2100' (Throttle Control Motor-Circuit Open). I brought our Forester back home, did some online research, and discovered that this code typically indicates a thermal control valve assembly (TCVA) failure. Our vehicle's 60,000-mile powertrain warranty had just expired but fortunately, we live near a reputable repair shop which was able to take the Forester in the next day, confirm the codes and TVCA failure, and then make the repair. Further research revealed that this appears to be a widespread quality control problem and typically costs affected owners between $1,100 and $2,000 to fix beyond the expired standard 35,000 mile /60,0000 mile powertrain warranties. In fact, there is a Subaru Forester Owners thread that runs over 33 pages with 654 posts from other owners throughout the world reporting the very same failure over the past year, nearly always between 50,000 and 70,000 miles. (https://www.subaruforester.org/threads/2019-thermo-control-valve-assembly-and-warranty-merged-thread.823510/) This past week, a friend of mine who's an old school mechanic, took the old TCVA apart and discovered that coolant had actually leaked into the part's internal electronics and shorted them out, causing the failure. He was amazed that the short circuit did not damage my Forester's computer. It's certainly a design and manufacturing defect and a recall should be issued by Subaru.

Eye-sight system shutdown and the car, although it was drivable, ran rough. Since there is a huge reliance on the monitors as they are designed to "forward think" to aid the driver, this was a major disruption to the driving experience. Not knowing what the disabled components affected, was a huge cause for alarm. Upon seeing the check engine light come, my wife brought the car home and I hooked up my device to read the code (P26A3 - showed up). Then I looked up that code and was directed to multiple incidents where that very same thing has become frequent on this model and a few others like it. We called the Winston-Salem NC Subaru Dealer (Flow) and they suggested we bring the Forester in for a check. Once they checked the vehicle out and confirmed the code we mentioned, they told us the "TCV" problem was found on our vehicle and they have seen others with the same problem. They even had the parts in stock to make the repair that day! They kept the parts and said they were going to be sent back to Subaru of America for analysis.Interesting detail: once we drove the repaired vehicle, it ran better than it ever had and the only work they did was to fix the TCV issue (according to the repair paperwork).

The Thermo Control Valve had went out. When the valve went out, the Subaru Eyesight became disabled. This also turned off the forward collision, automatic emergency braking, blind spot warning, lane departure, and rear cross traffic warning and braking. Subaru has a service bulletin, 09-80-21, stating the issue.

Auto safety systems compromised with illumination of check engine light and engine temp warning light. Subaru dealership service department determined problem with Thermo Control Valve. Engine was not overheating as the vehicle was being driven in winter time, February in Alaska. Only indication of problem was indicator lights and reduced heat from cabin heat system. Vehicle went into "limp" mode as soon as warning lights illuminated, disabling advanced safety systems.

Driving uphill when the car suddenly jolted, lost power, and all warning lights became illuminated. All safety features were disabled as well. The sudden stop almost resulted in being rear ended and the car was barely drivable afterwards. Diagnostic trouble codes: P26A6, P2004, P2005, P060B, P0191, P24B9, P2200, P2400.

The engines shut down or stalled on me while driving completely. It did not accelerate when I was trying to move the car off the road. the engines sputtered / shaken , all the lights came up on the dash board, smokes started to come out of my engines. this problem is similar to the recent Subaru recall on the fuel pump. Please add 2019 Forester on your list of recalls. This is a serious and dangerous issue, i could have been killed if I was dring on the freeway. I was lucky it shut down on a little local street when I was dring slow , about 30 - 35 mpg. Imagine if this happened on the freeway, it could have created a chain reaction , and a lot more people will be involved, and deaths might be involved. Please add Subaru 2019 forester sport on your list immediately because deaths involved. Thank you.

On 10/7/2022, all the warning lights came on and stayed on, even after tightening the fuel cap and replacing the battery. I brought the car to Ocala Subaru this morning, and paid for a diagnostic that shows the Thermal Control Valve needs replacement. Apparently this is now a common problem on this year and model Subaru. I was told that this is not covered under the powertrain warranty, even though it is part of the engine assembly, and is a very expensive repair, even though the car has only 43,669 miles on it. I was told the part is on national back order and that the car is okay to drive, but that most of the safety systems that have the lit warning lights are now disabled. This is the car my wife uses to transport our 6-year-old granddaughter to school and swim practice and events, as well as elsewhere, and I feel this has compromised their safety and warrants a recall.

check engine light came on end of August. Took into dealership early September (9/6/22) to find that the P26A3 code or Engine Coolant bypass Valve is defective. I have 47k miles on my 2019 Forester, so luckily it is under the powertrain warranty ( up to 60k). however, dealership is backlogged and waiting on parts . they were giving out loaners but can no longer do it due to the long lead time on parts as well as no place to let vehicles park for several months. I have been driving my vehicle at a limited capacity, however, living in Michigan the days are getting colder, and the need for my defrost to work properly is a must. with this issue my vehicles heating system is never warming up . thus causing a safety issue when I cannot use defrost on my car while waiting for parts to come in. I understand that all manufactured car parts have long lead times right now, however this is now a safety issue when not being able to use the defrost (directly related to this needed repair) on my 2019 forester.

The problem seems to be a faulty Thermo Control Valve Assembly. When I started the car, the dashboard lit up with several warning signs including the check engine light and 6 or 7 other warning lights. I also received texts and emails from Subaru saying to have my vehicle serviced ASAP. My 2019 Forester only has about 16,000 miles on the odometer. Continuing to drive would cause damage to the engine and potentially the car could abruptly stop on its own. Our car has been in the service department of our dealership for five weeks. I just received a call this morning that we had to return the loaner rental today, but that the thermal control valve is not expected until mid- or late-October. (It is now September 20.) I researched several Subaru blogs, and it seems that many others are having the same issue with their Foresters. Our dealership has five automobiles in their service department waiting for this part (and this is only one dealership). I also researched the Subaru service bulletins and see that they have a newly-designed thermo control valve assembly (same part number as the old one but a different date etched into the part). Apparently this has been an issue known by Subaru since at least September 2021 when their service bulletin came out. It seems that with so many owners having the same issues, there should be a recall and part replacement without cost to the owners.

The problem cited below is on a 2019 Subaru Forester with 20,101 miles. The 'check engine' light came on when I started my vehicle as well as all the ADAS warning lights came on. All ADAS were inoperable. The car was drivable so I cautiously drove it to a Subaru dealership. While driving, I noticed the engine never warmed up. Running a cold engine causes an emissions problem and may be a violation of an EPA standard. The problem was diagnosed by the dealership as a faulty Thermo Control Valve Assembly, Part Number (21319AA010). Upon researching the problem on www.SubaruForester.org, I discovered over 240 similar postings about the same complaint on the same model car. I consider this to be a Safey issue with a potential of significant engine damage causing engine failure as well as making all the ADAS inoperable. Subaru of America is aware of the extent of this problem and should be made liable for recalling these vehicles and fixing this safety problem. The vehicle is currently (since Aug. 23, 2022) at the dealership awaiting a back-ordered part. I am currently negotiating with Subaru to have the part repaired under the 5 year/60,000 mile powertrain warranty. Please look into this issue since so many other owners of this vehicle are having this same issue. Thank You.
