2019 Subaru Forester

We have replaced the battery twice and likely will need a third battery soon. I have learned that there is a known issue with the DCM trying to connect using 3G. This is causing a parasitic drain on the battery. The vehicle will fail to start. This has occurred many times over the last few years. We have just learned of the problem.

Dear National Transportation Safety Board, I would like to bring a situation that happened to me while driving my 2019 Subaru Forester last Saturday March 7th, 2026 at 10:40am. I was coming back to my house from an errand. While waiting for my garage door to go all the way up, my car suddenly accelerated forcefully and lunged through the garage and into my home through the wall. There was a chest freezer that was against the wall in the garage which was against the back wall. This freezer was also taken through the wall and into my laundry room. The freezer was crushed. The front of the car and tires were up through the wall and in the home. There was a water spigot also in the garage that came into my home that broke and dispersed water. The furnace was crushed, water heater damaged, washer and dryer damaged, a water cooler damaged along with crushed metal bifold doors that were ripped off HVAC closet. And other things in garage totally crushed. Thankfully, no-one was killed. I was barely able to get out of car as when it suddenly accelerated, and clipped the bottom of garage door that wasn’t finished being up, then it went towards the left and corner of garage instead of of how I would normally pull in and park which would have been straight and middle of garage. The car went so fast and would not stop until it had hit the items in house that would make it not be able to go any further. This vehicle definitely had something faulty with it that caused this car to suddenly take off and crash. And the air bags did not go off. Surprised with such a forceful impact. My car had 62,039 miles on it and was well maintained. I bought brand new at Dellenbach Subaru in Fort Collins, CO in December 2018. Please contact me at [XXX] nk you so much in advance, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2019 Subaru Forester. The contact stated that while driving at an undisclosed speed, the vehicle stalled, with several unknown warning lights intermittently illuminated. The failure had occurred on several occasions. The vehicle was taken to an independent mechanic, where it was diagnosed with thermal control valve failure. The vehicle was repaired; however, the failure persisted. The vehicle was taken to a dealer, where it was diagnosed, and it was determined that the thermal control valve needed to be replaced. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.

Pipa Rx Aire base latch system appeared to latch when it wasn’t secured to the anchor. I moved the base between vehicles. When reattaching the base, the right indicator clicked and turned green without actually being attached to the anchor. The seat felt secure, but shifted when I removed the carrier, which is when I realized it was not attached. Photo of latch system showing green and of manufacturer information is attached.

The Thermal Control Valve on my Subaru Forester failed while I was driving recently. The failure caused the car to stop while making a turn. It was a very frightening experience. Luckily at that time the traffic was light. The car was towed to a Subaru dealer, and the Thermal Control Valve was replaced at no charge because Subaru extended the factory warranty. Subaru should have had a Recall Notice put out because this problem could cause serious bodily injury.

Engine lost power and was misfiring while many warning symbols appeared on the dash. There was a divider separating the lanes. The car coasted to almost to a stop, but the engine chugged enough to slowly turn left at the first opening in the divider and just barely made it off the main road. The engine stopped. I restarted it several times. The engine was misfiring barely running. The electric brake was applied on its own. The car did not respond to moving the shift selector out of park, so the car was immobilized. I put the 4-way flashers on and called AAA. There seemed to be no way for me to move it out of park or release the electronic parking brake. AAA could not respond quickly and suggested I call the police to divert traffic around my car for safety which I did. The tow truck operator was able to disengage the wheels and was able to flatbed it to the nearest repair shop. This being Saturday 1/3/26 it wasn't until Tuesday the repair shop determined the car would not run long enough to provide a reliable diagnosis due to the multiple trouble codes coming up on the computer analysis. I had the car towed to the nearest Subaru dealership who replaced the thermos control valve under their warranty extension. The dealership said usually when this part fails it just triggers a check engine light and not the dangerous situation I experienced. I believe a recall to replace this part should be issued on all cars with this defective part as its failure can cause a dangerous situation without warning.

I had a tire rotation at my Subaru dealer in 12/2024. Two weeks later I had a flat and could not break two lug nuts. Tire repair dealer found that the lug bolts had been stripped. I had the remaining lug bolts examined by the dealer and a 3rd was found stripped. All three had to be replaced. I underwent tire rotation on 12/11/2025 and dealer found a fourth lug bolt stripped which needed replacement. I was assured this was not the fault of the mechanics and was instead told that this was a manufacturer problem with the lug bolts. If this is true, there are a host of Subaru's out there with lug nuts that cannot be user removed to repair a flat. Although when stripped, the lug nuts are apparently firmly attached, does this represent a wheel / tire failure issue? Thanks for your attention.

The contact owned a 2019 Subaru Forester. The contact stated that while driving and merging onto the highway in the rain approximately 62 MPH, the contact’s vehicle was rear-ended by another vehicle that was driving erratically. Due to the impact, the vehicle spun out of control approximately 3-4 times and the vehicle bounced off the concrete highway sound barrier. The vehicle continued to spin out of control and struck the barrier wall on the passenger’s side before coming to a stop. The contact stated that the rear driver’s axle fractured and ended up on top of the wheel, and the wheel was flat on the ground. The contact stated that the air bags failed to deploy upon impact or during the crash. The vehicle was not drivable. The contact and his wife were transported to the hospital and were both treated for whiplash, body pain, and pain to the head and neck. The contact also had a throbbing headache from the crash. The contact and his wife both received CT scans that showed no signs of injuries. The other driver also spun out of control and struck the metal guardrail located in the middle of the highway. The contact stated that the other driver had not received medical attention at the scene. A Police Report was filed. The vehicle was towed to a collision yard where it remained. The insurance company had not inspected the vehicle; however, the contact expected that the vehicle would be deemed a total loss. The contact stated that the driver who caused the accident was cited by the Police for causing the crash. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 71,400.

Subaru Forester 2019 January - February of 2025: issue initially presented as the hatch beeping, indicating that it was not closing fully. The hatch would not pop back up as if something was in the way, just remain down & continue beeping. The car would then not start, with only the hatch beeping noise (beep beep beep) going off. When I drove it, it kept warning me that the hatch wasn't shut completely. After I parked it in the garage, the next morning it would be dead. The issue was supposedly resolved in February of 2025 as I replaced the battery on my own and replaced this part: 29182AA060. Schomp Subuaru reported no issues with their diagnostic tests. November 30th - December 2025: I started the car just fine. When I opened the trunk and closed it, it gave me three beeps and wouldn't fully close, even if I pushed it shut and locked it. The next morning, the car would not start - the battery was dead. The tow company also could not jump start the car. As the car was being towed, the hatch alert was the only thing working/beeping. Even when not trying to use the hatch. I have used the car every single day up until this issue started. I have not left the keys in the car. The car is now back at the dealership. The unreliability of this can/has left me and my passengers stranded and cold. The dealership found no issue the last time this occurred even though there was a class action lawsuit about this exact issue, but somehow my car was not considered included. I cannot have Subaru tell me that there is no issue again.

I have reported this before but it never went anywhere. When at a red light or in a traffic slowdown, the car will activate the auto start/stop system. Three times in the past 2 days, the car would not turn back on and required me to turn the car off and back on again. You can imagine that this leaves me in a dangerous situation because the cars behind me see a green light and get ready to move, or they see traffic clearing up and they get ready to move. I am forced to turn my car off and back on again in the middle of a 4 lane highway or on a busy city street. I get cursed at and nearly rear ended each time this happens. I did an internet search and there are entire threads dedicated to this exact problem with this subaru model and year. There should be a recall. It is very unsafe

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 I was driving on a major road, the car appeared to sense an issue and automatically started to brake. While I was a road with 55mph drivers, my car was forcing me to stop. May warning light appeared; Eyesight Issue, Check Engine, Brake and many others. I was able to disengage the crash prevention manually and continue to drive. When I took it to my mechanic, he told me all the codes went to a Technical Service Bulletin for the Thermo Control Valve. He reset the codes and told me to take it to Subaru for an under warranty repair. Once I left the mechanic, I was travelling home and the car had the same issues, again while driving on a very busy road. This time I could not disengage the system, and I struggled to get the car over to the left shoulder. It was very narrow, and not safe. I ended up having to have the car towed to the dealer. The dealer did fix the car, under warranty. However, twice I was caught on busy roads in a very dangerous situation. I am very glad that I was not injured, nor those that came to rescue me. But this should not have happened. The Technical Service Bulletin was issued on April of 2024 and I had no idea.

The auto stop/start feature occasionally causes the entire vehicle to totally shut off. This happened 3 times 2 years ago and I was to it was a low battery. On 10/4/25, the car is stopped at a red light on a four lane highway and when my wife stepped on the gas to start, the vehicle totally shut off. After panicking, I helped her turn the electronics on in order to start the flashers, then move the vehicle from drive to park, and then restart the vehicle. With cars moving at 55 miles an hour toward a green light we were very concerned about getting hit from behind. Luckily, we were not hit. The Subaru dealer then suggested the problem might be the ECM and they charged us $203 for a software update. It is not clear what causes this total vehicle shutdown but it is a significant safety issue that puts the vehicle and occupants at risk. I hope the Subaru engineers have identified and fixed this issue in future models.

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

Car has died 10+ times in the last 2 weeks. Will not hold a charge and it’s getting to the point that my car is dying in the middle of the road, during heavy traffic. That or the car will just not start unless jumped

- *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.

About a month ago while approaching a stop light turning green at a busy intersection, I was slowing into the left turning lane when my car just stopped. No avoidance, no alerts. I had a semi behind me who started pulling out around me in heavy traffic. I could use my flashers. I turned the car off, then on and it finally restarted. This is a 2019 Subaru Forester, original owner, only one incident - but it was definitely weird, and unsafe!

My Subaru smelled like gas and caught on fire while I was driving to work less than 72 hours after it left the service department at the local Subaru dealership. Earlier that week I dropped the car off for service due to a check engine light and multiple other warning lights on the dashboard. The check engine light was determined to be due to a faulty thermo control valve (a known issue on several models of 2019-2021 Subarus). During that service appointment, the thermo control valve was replaced under warranty, the 60000 mile service, state inspection, and an oil change/tire rotation were completed. The morning of the incident, the car smelled like gas, but there were no warning lights on the dashboard and the temperature and gas gauges were all in range. While looking for a safe place to pull over on the side of the road, the gas smell worsened, I heard a pop, the check engine light and every single other light on the dashboard lit up, it smelled like burning jet fuel, and the front of the car was smoking and there were flames, and all mechanical and electrical control of the vehicle was compromised. The car coasted to the side of the right lane. I was unable to operate the gear shift to put the car in park. I opened the driver’s side door, removed my seatbelt, grabbed my backpack, lunch bag, and phone, and exited the vehicle while it was still rolling. I ran around the back of the car to get onto the side walk. Flaming, melting pieces of plastic were coming off the bottom of the car. Flames and smoke were visible on the front hood of the car. I called 911 while the car continued to roll across several lanes onto the other side of the road. The burning car rolled and hit a guardrail on the opposite side of the road and continued to burn until the local Fire Department arrived on scene. Local police and the fire inspector wrote reports. My insurance declared the car a total loss. I have informed the local dealership and worked to get them access to the vehicle.

The contact owned a 2019 Subaru Forester. The contact stated that while driving on a main road at 30 MPH upon approaching a red light the contact attempted to slow down by depressing the brake pedal, however the vehicle would not slow down, the contact proceeded to swerve to the right and in the process crashed into a lamppost and power pole with the entire front end of the vehicle. There was property damage to both the lamppost and the power pole, and the vehicle came to a stop upon impact. The airbags were deployed. The vehicle was going 30 MPH at the time of the crash. The vehicle was towed to a local junk yard. No warning lights were illuminated. A police report was filed. The vehicle was destroyed. The contact was injured, and she was seated in the driver's seat. No one outside of the vehicle was reported to be injured. The contact sustained injuries to her chest, abdomen, and shins. Medical treatment was required for the injuries. The approximate failure mileage was 50,000.
