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 ..

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 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

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!

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

At a stop light, auto stop engaged. When foot put on gas, engine died and every warning light the car has appeared on the dash board. It took several tries, but I did get the car started again. Took to dealer who confirmed the incident and replaced the starter at 38, 126 miles. The fuel pump relay was also replaced. After this incident, the cancel auto stop/start button was used most of the time when driving the car. 10 months later, forgetting to engage the cancel button, and the auto stop/start working, the car once again died at an intersection. We were able to get it restarted and it went back to the dealer. They again confirmed that the starter was faulty and once again replaced it and the fuel pump relay. This occurred at 44,770 miles. Thankfully, In both incidents, we were stopped at intersections with traffic lights. The first was in a left turn lane surrounded by cars on a hill. I was able to engage the parking brake before I rolled back into anyone. The second incident was at a flat intersection. Others were stopped around us and no one was approaching us with speed. My concern is that this will occur when waiting to make a left turn at an intersection and the car would roll forward into traffic. Another concern is if highway traffic is stopped and then starts moving again. If the car stalls and won't restart, traffic around you would go forward and traffic behind them would approach your stalled car at speed. Someone is going to be killed from this problem if they haven't been already.

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.

During severe stop/go, thick, holiday traffic on I-495 (DC Beltway), during daylight hours, once AGAIN (this has happened several times before), the auto engine shutoff feature catastrophically malfunctioned, turning the car off, and simultaneously, activated the entirety of the dashboard to flash on/off, causing nearly every indicator light to come on, and then had difficulty restarting. This has been brought to Subaru's attention multiple times and they essentially have washed their hands of it and stating since they can't duplicate it, it essentially must not be occurring and they cannot repair it.
