2019 SUBARU FORESTER Electrical System Problems

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...

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...

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....

- *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...

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

My 2019 forester touring. The sound system will randomly raise to extremely high volume. It’s an extremely loud, distorted, static version of what you were listening to. You cannot turn it down with the volume control with knob or power it off. It is unresponsive and you must wait 5-10 seconds for the sound to go back to normal. Not knowing when it’s going to happen scares the heck out of me. I’m afraid to drive off the road or cause an accident when being startled in this way. This has been happening since one month of my owning the car. (Ordered it, got it October of 2018] I’ve had it to the dealer numerous times and called Subaru of America. I was told if the problem doesn’t duplicate at the dealer nothing can be done. I only have 24k miles on it. It’s not safe! I now a have...

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.

The contact owns a 2019 Subaru Forester. The contact stated while driving approximately 55 MPH, there was an alarm heard before several unknown warning lights illuminated and the vehicle lost motive power and decelerated to 35 MPH. The contact shifted to neutral to restart the vehicle. The contact pulled over to the side of the road and waited for a while before continuing to drive. The eyesight, brake light, automatic transmission, oil temp, and several other warning lights illuminated intermittently. The failure occurred a second time on the same day. The dealer was contacted and advised the contact to take the vehicle to the dealer whenever the lights were illuminated. The vehicle had not been taken to the dealer to be diagnosed or repaired. The manufacturer was made aware of the failure and referred the contact to the dealer for assistance. The failure mileage was 119,000.

The issue started last year over a period of several months when my car kept stalling at a traffic light. After stopping on a red light my car stalled. I had to shut off the car then restart to get it going. Had the battery replaced and problem was gone until this week. Car stalled at the traffic light again (in the middle of busy downtown and being the 1st car at the intersection), but this time it wouldn't restart and battery light turned on when attemped to restart. Called Subaru road assist and requested jumpstart service. While waiting for road assist to arrive, attempted to jumpstarts with a manual jump starter, but didn't work. Attempted with the jumpstart cables, but still didn't work. Subaru assist arrived and was able to successfully jumpstart my car. The Subaru tech assessed my battery and showed 75% battery life. Drove home on the...

[XXX], driving home, dark at [XXX] in Airway Heights WA. About 10 mins to home, lights in dashboard suddenly lit (brake, check engine, battery icon, water temp icon, 2 yellow colored pictures that had the word “off”, park, ABS, exclamation point next to a circle that had a symbol in circle like a Mercedes Benz, and another symbol colored yellow). I kept driving with very little power in the car and it was hard turning the wheels to left or right turns. I was so scared thinking I would be stranded in the middle of the street! Made it to my carport and drove it in. Turned off car; attempted to restart but didn’t, and during the times I started the car, it would make a stuttering noise. The lights that lit up remained, wouldn’t turn off until attempt to start again when the lights all turned off. INFORMATION REDACTED...

As I was driving, every warning light came on, my car emitted a high pitched alarm and the car stopped working. This happened twice. I had to put my car in park. Turn off the car and turn it back on to make it driveable. I took it to the dealer and was informed that the battery and starter required replacement. The battery was covered by an extended warranty (I paid $100 or 20% of the cost), but the starter was not covered by any warranty since my car has 41K miles and is 5 yrs old. I contacted Subaru and they agreed to pay $800 towards the $1209.13 repair. My Subaru Case # 241016-1801159. I believe my starter failed because of the automatic start/stop engine feature. I asked the dealer if the starter failure could have been detected during a regular maintenance and they said no.

After starting these lights came on the dashboard: check engine, flashing I drive, no eyesight, rab off. Seems related to start/stop system which randomly dies when I release the brake. The whole dash lights up and I have to put the car in P and start it again. Thanks.

Car suddenly stopped accelerating several times over the course of several months, at seemingly random speeds, once even at a full stop when attemptign to begin acceleration. Required to turn it off and on again (in park, break still works) and it works again. I towed the car to the dealership, and they told me after a few days that they could not recreate the issue and nothing was certifiably wrong with it. The only thing that came up on the sceen was the EYE LIGHT system wording with a slash through it.

The battery on my 2019 Subaru Forester was replaced in September 2022. It was the best battery available offered at Les Schwab. But a few days ago, the battery was completely dead again and couldn’t even be jump started with my Jump N Carry after being parked in my garage for ~3 weeks. After taking out the battery and getting it fully recharged at Les Schwab, they also tested the battery saying it’s still in good shape. I suspect there is parasitic battery drain issue going on with this model.

I have had multiple issues with my car for the past month. First, my rear right wheel has been making a fan-like sound when going above 35mph and it gets louder until 70mph. It is most likely the wheel bearings going out but, I only have around 50,000 miles on the car. This seems to be a common issue with Foresters. Secondly, my rear Harman Kardon speakers have stopped working. This also appears to be a recurring issue with Forester's, with both their standard and premium sound systems. Lastly, my engine check light turned on and shut off my adaptive cruise control, forward collision warning, emergency braking, and rear automatic braking. I'm surprised that these issues are still happening to Subaru since they have been complained about by consumers for years.

most of the safety quiet. motor cut out, eyesight quiet working, check engine light came on service person said the diagnostic showed a code p2682 engine coolant bypass valve control low. steering light came on. No prior warnings. happened while driving at speed limit on interstate.

An electrical failure of the auto start/stop feature led to an unavoidable accident. I came to a stoplight, going slightly uphill, and the car shut off as designed. Releasing the brake re-engages the starter to continue driving, however when I released the brake, the car’s electrical system went haywire and the car immediately rolled BACKWARDS, damaging the car behind me. I took it to Subaru and the mechanic said the battery was low, but the car is designed NOT to initiate the start/stop feature, to prevent this from happening. They acknowledged that the accident was not my fault, but provided no further assistance. I was found at fault in the accident despite having no control over the scenario.

4/2/2024 at 5:30am my Eyesight system flashed a message in orange that the Eyesight system was off - not temporarily disabled. This is NOT due to an obstruction of the cameras by weather/glare/dirt etc. All functions controlled by Eyesight including lane departure, adaptive cruise control, and forward emergency braking, as well as reverse automatic braking are disabled by this malfunction. I removed the negative lead from my battery in an attempt to reset the system which did not clear the error. No check engine light accompanied this error and all other systems seem to be functioning normally.

Start / stop feature. Multiple incidents. Continuing issue. Stop at a light or in traffic. The car turns off. Let off the brake the car completely looses power sometimes or dies. Need to move shifter to park to restart. When the vehicle dies completely. Unable to move shifter of use hazards. This has happened on the highway at stop lights leaving me stranded in the middle of the road with no vehicle power. Or having to restart. Battery, starter and Alternator have been tested and are good. Safety issue.

My 2019 Suburu Forester battery will not hold a charge. Whenever I want to use it, my husband must jump the Forester with cables from his car's battery. I am careful not to park it for long and use it for trips to dentist, doctor, and other necessities. We bought the Suburu Forester brand new off the car lot in 2019. The car has under 3k miles of use--it looks in perfect condition. We've changed batteries but that did not solve the start up problem. It is a safety hazard depending upon where I have to stop the car. The "incident" is one of many recurrences. After 7 days of nonuse, parked in my garage, the car fails to start.

All of a sudden, the eyesight and collision prevention stopped working, the check engine light came on, the blue light thermostat indicator came on. We had no heat. The flashing "S" (sportsmode indicator) came on. We were driving on the highway and still over an hour from home. It was snowing, we could not adequately clear the windshield of fog so our visibility was severely compromised. We lost all Eye Sight capability which meant that we were vulnerable if there was ever a crash or an obstruction in the roadway.

On Friday, December 15, 2023 I started my car, Subaru Forester Touring 2019. After starting these lights came on the dashboard: check engine, flashing S drive, no eyesight, RAB off. I was reading online that there have been complaints to NHTSA similar to my problem ( NHTSA ID # 11490232, 12479843, 11511658, 11490977, 11479843, 11499756, 11480952, 11491752, 11474804) to name a few reports.This has never happenedbefore. The mileage on my car is about 54,400 miles at time of incident. It seems to me that there is a pattern here that needs to be resolved and the owners informed so they can get if fixed before it happens and causes safety problems for Subaru Forester owners. I am kindly asking your office to seriously look into this specific problem and help us, the consumers, to inform Subaru to fix these issues. I thank you for taking the time to read my...

The original battery does not support the CAN system and replacing the battery does resolve the issue. The system will shut off while stopped at a light to save fuel, and turn back on when you press on the brake or the gas. There is an error where the vehicle will try to start itself when you’re not even cranking it. This can be dangerous if the car shuts off at a light and won’t turn back on because the feature drains the battery. This needs to be a recall as Subaru is aware of the issue and implemented a new battery for the vehicles and want to charge double. Why should the consumer pay for something that the company is aware is a problem? And came up with a solution to the problem, but is trying to profit off of it instead of fixing their mistake?

On November 30th around 5:30 PM on [XXX] my wife struck and killed a 6 point buck. Thankfully a SC Highway officer was coming in the opposite direction saw the accident and aided my wife in getting out of the car as he had seen a fire in the engine compartment area. Shortly thereafter the car exploded and was engulfed in flames and totally destroyed. Neither the patrol officer nor the tow operator can remember an auto fire resulting from striking a deer.

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.

I own a 2019 Subaru Forester. Approximately 5 months ago, I experienced a failure in the auto start-stop feature. My car intermittently shuts down when stopped at traffic lights or in the middle of an intersection. Subaru conducted a diagnostic assessment to address the issue, but they couldn't identify any problems. This has happened about six times within the last five months. They claim to have never encountered this issue before. The temporary solution is to turn off the car and restart it, which is not safe when it occurs in the middle of an intersection. Following my dealership's recommendation, I replaced my battery with a standard EFB battery, However, the same issues persisted. Notably, the problem consistently occurs after driving on the highway for approximately 60-80 minutes and then coming to a stop at traffic lights. It is evident that the issue is not related to the battery. This...

Three times in the last week or so, coming to a stop, in traffic, the car throws a warning about the EyeSight not working and it shuts the car off. The first time I was still rolling and had not come to a stop. The other two times I was just barely stopped and it happened. It would be horrible if it happened while driving fast. You have to put it in park and hit the start button to turn the electrical off and then hit the button again to start the car. Windshield is clean. No visible obstruction to the camera system. Clear weather every time. No rain. Daytime driving.

Subaru has issued a service bulletin regarding this issue. The vehicles auto engine on/off (gas saving feature) fails to restart while driving due to OEM battery is known to be too weak. Only way to resolve the issue is to replace with higher capacity battery requiring new battery tray and additional new equipment. Current, customer has to pay repairs out of warranty. Incidents are frequent and reoccurring.

This is a follow up from previous complaint 11525953 dated 6/8/2023. My subaru forester stalled again on 8/2 at an intersection after 15 minutes of driving, and then again on 10/4 at an intersection after 45 minutes of highway driving. There are no warning signals or any indication of engine problems. I replaced the air filter in June hoping that might solve the issue.

1 . TERMAL CONTROL VALVE 2. TRAVELING OUT OF STATE AND ENGINE LIGHT CAME ON 3. WARNING LIGHT (CHECK ENGINE WAS ON) 4 CONFIRMNED BY DEALER 5. ALL LIGHTS ON DASH BOARDS ON

The contact owns a 2019 Subaru Forester. The contact stated while driving 60 MPH in a thunderstorm, the vehicle lost motive power inadvertently. The check engine, the Vehicle Dynamic Control, and the Eyesight Driver Assist system warning lights were illuminated. The contact was able to pull to the side of the road. The contact stated that the engine continued running, and the instrument panel functions were operable; however, the vehicle failed to respond upon depressing the accelerator pedal. The vehicle was towed to the local dealer, and the vehicle operated as needed. The dealer test-drove the vehicle but could not determine the cause of the failure. The contact stated that she picked up the vehicle; however, the failure recurred while driving. The vehicle was taken back to the dealer, and the dealer diagnosed that water was leaking out of the thermal control valve and onto the electric wiring. The vehicle...

2019 subaru forester failed thermo control valve. There are literally 1000s of complaints on this issue and SOA refuses to issue a recall. Subaru has issued a bulletin to replace the faulty design with redesigned part. When this fails the car goes into limp mode and all lights come on. Very dangerous and quote frankly completely irresponsible that subaru refuses to recall this failure. I am out of warranty and it's minimum 2k to fix. I have a 2019 vehicle parked that I can't get Inspected and can't afford to fix because Subaru of America is trying to save money. Just a matter of time before this causes a tragic accident before they own up to recall.

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.

On our way to a vacation in NJ, we were driving on the expressway and a deer jumped over the rail into the hood of the car. The car immediately started to smoke ( dark black). We got out of the car, retrieved two luggage bags, and the car burst into flames. All within 60 seconds of hitting the deer. About five years ago, same thing happened to my daughter driving a Subaru WRX…. Twice in the same family….no recall?

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.

Sun roof malfunction. Would not open. Once open, went on highway and had to close it. This was distracting to me, driver, and put us all at risk for no weather protection or debris on highway. The sunroof malfunctioned again by not responded and would not close. No warning for any errors. Has not been inspected by insurance. It is available for inspection. Online forums show multiple people are having this issue!

Over a dozen times now, when at a traffic light, the automatic on/off feature turns the cars engine off. When you take your foot off the brake to reactivate the engine, there is an EyeSight Disabled warning and the car stalls and fails to turn off. You have to turn the car completely off to restart it. I have previously brought the car into a Subaru dealer for servicing after this happened. It has continued happening since then.

2019 Subaru Forester Premier. 6/29/23 All ok while driving for 3 hours on highways. Never had any issues before. I stopped car to take a break, when I restarted the car. All the warning lights lit ou and eye-site was off and could not be turned on. Check engine light on along with many others. Had 30 minutes more to go, stopped a few more times to check on the engine compartment - all ok. Brought it to the dealer today, 6/30/23, they were going to need 4 hours to replace a Thermo Coupler Valve? Issued a loaner car, and said Subaru will cover it under warranty even though it has expired. Only 24500 miles on a 2019 Forester.

Automatic Rear lift gate will not raise (but does unlatch); the lift gate cannot be raised manually after latch is released. One can only open it about 6 inches until there is heavy resistance- like the strut has seized or a sensor has triggered a brake. Now, the rear gate cannot be opened in an emergency.

The Starlink Infotainment system started to continually reboot despite any attempts to reset it. With the car shut off, the CD player began continuously spinning up then winding down. This drained the battery. I had to pull a fuse labeled BACKUP to prevent this from happening. This has rendered the backup camera unusable.

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...

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...

March 9, 2023 at 7 AM, I was driving in Philadelphia and traffic had slowed slightly and I was going 5 MPH, coming to a stop in traffic when my car completely "froze", and all the lights on the dashboard came on and it said "auto start disabled" and my car would not move. I tried to hit "start/stop" button but nothing worked and I tried to hit my blinkers so I could warn the cars behind me, but nothing worked in the car and it was stalled. This was the situation for 4 full minutes. I am lucky the cars behind me were paying attention and did not hit my car when it abruptly stopped like that with no warning at all. I am really concerned about this car's safety. This issue occurred to the same car in 2021 and I made an incident report then as well. The...

Apparently the electrical system drains the battery when the car is not being used. If I let my car sit for 3 days the battery will be dead when I come out to use it.

First, the driver's side window would not go up when rolled down, but instead went up and down on its own, until I stopped the car and restarted it. A few days after that, on Friday, January 13, 2023 while on my way to work, I was stopped at a traffic light. All of a sudden beeping started happening, the "Eyesight" light came on, other things were showing, and the car died. I was too freaked out to notice anything else. I put the car in park and restarted it, and it was fine. Today, January 16, 2023, the exact same thing happened when I was stopped at a traffic light, again on a very busy highway. I am extremely worried and will be contacting the dealership tomorrow.

The Thermo Control Valve has stopped working It causes the engine to overheat while drive. The windows fog up in the cold making it hard to because the defrost does not work Yes by an independent service center No No the engine light came while I was drive.

Battery drain quickly. Overnight battery drain. Car driven for over 40 miles and the following day the battery is drained and won't start. Car left for one week with out driving - battery drained and won't start.

Car stalls out sometimes when running while stopped. This is not the stop/start system. Also, driver door power window will sometimes raise and lower on its own.
