2020 SUBARU FORESTER Electrical System Problems

While driving on public roads, all dash warning lights illuminated simultaneously. The instrument cluster displayed “EyeSight OFF.” At the same time, the electronic parking brake engaged / the vehicle would not accelerate and required me to stop and shift to Park. The only way to restore drivability was to turn the vehicle off and restart. This has occurred intermittently, including in traffic, creating a serious safety hazard for myself and surrounding drivers.

The contact owns a 2020 Subaru Forester. The contact stated that while his wife was stopped at a red traffic light in the middle lane and surrounded by other vehicles, the auto START/STOP system engaged; however, when the brake pedal was released, the vehicle failed to restart. After several attempts, the vehicle eventually restarted, allowing the driver to safely pull over. There were no warning lights illuminated. The vehicle was towed to the local dealer, where it was diagnosed with a dead battery. The dealer advised the contact about turning off the auto START/STOP system. The battery had been marked as good on two separate occasions. The battery was replaced. The contact reached out to the manufacturer, who opened a case but confirmed there was no warranty coverage on the vehicle. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 36,585.

Mileage: 36,585

Car frequently dies and won't want to start. Have changed the battery already. Will come to a stop and it will just randomly shut down. Have had to shift to park and restart the car. This is unsafe.

2020 Subaru Forester periodically will stall out at a light or stop sign in heavy traffic. It then takes several attempts to restart. (Sometimes completely dead) My mechanic hasI changed the battery and checked the alternator, all in working order. It’s hard to figure out what is wrong because it doesn’t happen all the time.

We were traveling in rural California, 1 hour north of Bishop, CA on [XXX] when our vehicle's "Check Engine" light, "Parking Break" light, and several other lights lit up on our dashboard. Our car began to stall out immediately. We were able to pull off to the side of the road as best as we could as we were towing a camper at the time as well. We waited for 4 hours to get our vehicle and camper towed 1 hour away to a mechanic. The mechanic couldn't fix our car, but we were able to get an engine code reader to clear the codes as they came up. The closest Subaru dealership was 4 hours away in Las Vegas, NV. We had to drive through mountains and Death Valley. Despite using the engine code reader to clear codes every 30 seconds, our car stalled out 6 times on the way. The problem was the thermo control valve for P26A6, a known problem with Subaru vehicles like ours. We had our vehicle serviced in July 2025 for 60,000 miles and the dealership did not say anything about this known issue.

I, the owner of a 2020 Subaru Forester am writing to you in regards to an issue with my vehicle’s Eyesight program. Over the past month, there have been several instances where the Eyesight program fails and caused the vehicle to suddenly stop without warning. This prevents me from safely moving the vehicle to the side of the road as the car stops. In other words, the car abruptly stops on the spot. This creates an immediate danger to life and health to myself and to other motorists. This issue must be addressed immediately and the necessary steps taken to ensure the safety the driver, passengers and other motorists on the road. Thank you for understanding.

When stopped at an intersection the car stalled. It would not restart for three minutes and caused a dangerous situation for my family and children in the car while traffic was moving. There were no warning signs, lights, or engine codes. The problem is random and cannot reproduced. The car is available for inspection.

Parasitic battery drain

I was stopped at a red light and the engine stalled. It read "FOR SAFETY, AUTO RESTART DISABLED". All warning lights on the dashboard lit up. I had to put the car in park and restart it in order to drive. I was honked at and put in a dangerous position. This has happened at least twice now.

This has happened 8 times in a month span. The car is currently being looked at by the dealership and so far they can’t find anything wrong. When I’m stopped in traffic, my car’s engine turns off. Once the light turns green and I press on the accelerator I hear a beep and the car doesn’t move . The dashboard shows a few error messages and a message stating that the eyesight has been turned off. In order to get the car to work again I have to put it in park, turn it off, and turn it on again. It is particularly dangerous because the car won’t move when the light is green.

While driving, the vehicle's Automatic Stop-Start System Engaged as usual when the car came to a stop (e.g., at a red light or in traffic). However, when releasing the brake, the Automatic Stop-Start System failed to restart the engine. Not only it failed to restart the engine, but multiple attempts of manually start the engine all failed. And the car became stranded in the middle of road with heavy traffic. Had to call 911 and tow truck to get the vehicle out of the road. No dashboard warning or error message appeared prior to the failure. Never had issues with engine cold start prior to the failure. Basically, the battery was good to cold start the engine prior to the incident, but while driving when the car came to a stop at a red light for few seconds, the Automatic Stop-Start System's engagement somehow suddenly cause the battery not able to start the engine anymore. The issue poses a serious safety hazard, particularly if it occurs in traffic, at intersections, or on highways, as it may leave the car stranded in a dangerous location.

the [S] is constantly blinking, the check engine light On, the temperature light is on as cold, and the eye sight and anti collision is off.

Numerous times when using the "gas saving feature" when the engine stops after the brake is pressed, the car has stalled and I have had no control over the vehicle. I have had to turn on my emergency flashers and restart my car in order for it to move again. Luckily whenever it has happened for me I have been stopped on a flat surface, and not on a hill, but if this ever happened while I was trying to turn I would be T-boned, or if it ever happened while I was stopped on a hill I would roll backwards. This also increases the chances of me being rear ended, because the person behind me has to be paying attention that my car has stalled. My Apple Car Play has also not worked since I purchased the vehicle in 2020. Their only suggestion was that I needed to swap out my iPhone cord every few months, and then it may or may not work. Also what if I was not an Apple user?

I am writing to express serious concerns about the Auto Start-Stop feature, which poses a significant safety risk when it causes shutdowns in critical situations. Recently, my vehicle shut off due to Auto Start-Stop while in the express lane of a highway. A depleted battery prevented it from restarting, leaving me stranded without the ability to shift to neutral or activate brake lights and hazard signals. For 30 minutes, I was stuck in a vulnerable position, forcing high-speed traffic to swerve dangerously close to my vehicle. While the battery issue was a factor, the car would have remained running had I been able to turn it off manually once parked. Reports from other drivers indicate similar issues, including stalling, hesitation, and complete system failures. Given these risks, I urge the NHTSA to investigate this feature and require manufacturers to provide a permanent disable option rather than a temporary one that resets.

Periodically, the vehicle stalls at stop lights, stop signs, and in other situations when coming to a complete stop. Once the vehicle comes to a complete stop and turns off due to the auto-stop/start function, it stalls immediately after the car re-starts and you press the gas pedal. This leaves the vehicle stalled in intersections and in potentially dangerous conditions. You must engage park and restart the vehicle while stopped in the middle of traffic, which poses a significant safety risk. I believe this issue is related to the auto-stop/start functionality. The vehicle has been inspected by a Subaru dealer several times, but they claim they cannot reproduce the problem and there are no diagnostic codes or warning lights. No other mechanic has inspected the vehicle.

This has happened multiple times, is increasing in frequency. Stopped in traffic at a red light. The Auto Stop/Start was enabled and activated when stopped at the light. When the light turned green, tried to go, but the AS/S system failed. A “No Eyesight” warning flashed and disappeared; various symbol lights blinked across the instrument panel. Car would not start, hazards would not activate. After 10-20 seconds, I was able to put the car in park and restart the engine (would not start before then). No battery or check engine lights had been on previously, up to date on oil changes, 66k total miles, vehicle fully maintained at the nearest dealership. This was scary as I was stuck in the middle of the road on a state highway with traffic and cars behind me. Many people have reported this issue in Subarus and I’d like for this dangerous problem to be formally addressed.

My car completely lost power. I had driven to the stop light and was waiting when it lost power. It had no power for several minutes and was unresponsive to the ignition or anything else.

Stopped in traffic near a red light. The Auto Stop/Start was enabled and activated when stopped at the light. When the light turned green, tried to go, but the AS/S system failed. A “No Eyesight” warning flashed and disappeared; various symbol lights blinked. Car would not start, hazards would not activate. After 20-30 seconds, I was able to put the car in park and restart the engine (would not start before then). No battery or check engine lights had been on previously, up to date on oil changes, 35k total miles, and I had a quarter tank of gas. This was scary as I was stuck in the middle of the road with my children while cars behind me tried to pass on either side. Many people have reported this issue in Subarus and I’d like for this dangerous problem to be formally addressed.

The auto start stop feature has caused my car to shutdown with all lights lit on the dash in more than one scenario. In traffic on the freeway, I had my foot on the brake. It auto stopped. Then when the traffic was starting to move, I went to push the accelerator and the dashboard lights all lit up and the engine shut off completely. The car was still in drive but it was off. I had to shift the car into park and push the start button to start the engine back up. It has happened before at traffic lights with the same outcomes. I went to subaru dealer and they said some of the batteries were faulty and replaced it but that is not the issue since it is still happening. It is dangerous in traffic!

Stopped at a red light at busy intersection. The Auto Stop/Start was enabled and activated when stopped at the light. When the light turned green, tried to go, but the AS/S system failed. A “No Eyesight” warning flashed and disappeared; various symbol lights blinked. Car would not start. Driver activated hazard lights, which flashed for no longer than three to five minutes before stopping completely. While car was stalled in traffic, a few lights continued to blink on the dash.

Vehicle traveling W on [XXX] Bryan TX. Automobile suddenly started shaking and not developing power, Driver was able to pull off on the shoulder barely clearing the #2 lane. The engine would crank but not sustain operation. The auto required transport to the home garaging location. Subsequent analysis of the fuel showed it to be gasoline, no water, lacked appearance of any foreign matter. With the ignition on 12V were detected at the gas tank terminal, however the in tank pump would not produce fuel flow at the connection at the top of the tank. Had the vehicle been operating in the #1 lane it may not have been possible to clear the traveled lanes thus causing a traffic safety problem. A State Trooper did provide protection until the vehicle was transported. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2020 Subaru Forester. The contact stated while at a complete stop, the automatic START/STOP, the feature intermittently failed to operate upon depression of the accelerator pedal. The contact stated that the failure occurred without warning. The contact stated that once the vehicle was restarted, the vehicle resumed normal operation. The vehicle was taken to the dealer where the contact was informed that the failure was related to the battery. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 80,000.

Mileage: 80,000

The head unit suddenly stopped working. It unfortunately isn’t covered Under warranty. The screen consistently turns on and off.

A week after my routine oil changed at 31K, the check engine light along with flashing "s" pop up. The next day the check engine disappeared. I was some what happy and continue to drive car as normal for 2 days, then check engine light came back again and this time is staying for good. I just can't believed that 4 years old car is having this issue. I've owned so many cars prior to this 2020 Subaru Forester, never once that those cars have problems like this one. I feel that i'm at risk driving without no eyesight or collision prevention warning.. when the check engine comes on, those two things are disable. After a long research and reading about so many people with same issues, i feel that they should be a recalling to fix the thermal valve control.

Within one month the same thing happened. I turn on the car and the eyesight warning light is on (eyesight feature disabled), flashing "S" drive is on, "break" light is on, and check engine light is on. Due to this cruise control isn't working. My plan was to take it to a mechanic/dealership that Monday. By Monday morning, after about 15 minutes of driving, all warning signs disappeared. This exact thing happened a few weeks later (this morning). I started googling issues and seems like this is an issue for many customers and is just a malfunctioning Thermo Control Valve, no actual problem. What do I do about this? This is much less important - but also seems like a quality issue, at drivers side, the seat cover is starting to crack, looking like this is car is over 10 years old, we've had it for less than 4 years and this shouldn't be happening on a car of this caliber.

I picked-up my new 2020 Subaru Forester on January 2, 2020. Within two years the battery became too weak to start the engine. Since then, I've had to repeatedly charge the battery. Now a battery maintainer is constantly connected to the battery. I've seen online reports that multiple late model Subarus have had battery issues, and that Subaru of America voluntarily replaced batteries and addressed related electrical issues for some of its customers. Subaru of America has all of my contact information, but I was never informed of their voluntary fix of the battery issue. Due to the fact that I wasn't contacted about the battery failure issue, do I now have any recourse? Many late model Subarus have an automatic engine stop/start feature. I've read reports of Subarus not restarting in traffic, I therefore do not feel safe driving my 2020 Subaru Forester. Why didn't this dangerous problem trigger an NHTSA recall?

The thermo valve leaked into connector, causing engine to shut down abruptly to prevent overheating. This happened at 70 mph on interstate highway in traffic. Part was replaced with modified thermo valve later. Barely able to coast to narrow shoulder flanked by deep ditch, with vehicle very close to interstate traffic, so much so that exit from vehicle ill-advised. After towing, vehicle was serviced by Subaru dealer. At time of part failure many warning lights & messages appeared, but not before the event.

The thermo control valve on vehicle failed on 2020 Subaru Forester which is causing vehicle to loose acceleration, multiple errors codes displaying on the vehicle instrument dash panel and no heat in the vehicle (see attached photo for reference). The failure of this device could cause a vehicle fire depending on what position/ and or state the thermo valve failed in. There needs to be a manufacturer recall on this particular part as there is numerous amounts of complaints and issues. Subaru needs to make it right with the customer. we need to drive safe vehicles on the road.

Vehicle shuts off while driving.

1-16-24:car wouldn’t open and start; jump-started by AAA to dealer; dealer kept overnight & checked battery: said charge held, ready to go home. 1-30-24, 4 pm-ish: able to start n drive, but check engine& eyesight warning light came on- late in day, so didn’t drive to dealer. 1-31-24: car dead; jump-started by AAA again & drove to dealer. On 2-1-24, dealer sends a video & says replaced battery, but check engine light & eye sight warning light still on; investigated further & found there was a lot of water that had pooled under the passenger seat & caused some corrosion- I.e.: shorted out electrical system. I asked dealer to report to Subaru since this seemed like a car defect. 2-9-24- dealer says Subaru won’t repair it at their expense and it’s a 25 hour job & will cost a lot. Dealer wanted me to file a claim with my insurance, but car was not driven through rain, high water, or stored in a flooded garage or on a flooded street. The water in the car seems like a design defect on the part of Subaru.

I started the car to make a trip to town to run some errands. When I cranked the engine the Check Engine light came on. The S for Sport Mode was flashing and a No Eyesight warning came on. Also SRS Side Airbag light came on to indicate it was not working. And another light came on showing a car going out of its lane, but I don't know if it was the Lane Keep Assist light or not.

Driving my 2020 Subaru Forrester on 1/26/24, at night. Stopped at traffic light. Car started shaking, dash lights system lights came on. Turned off car and restarted. Car would not accelerate. Had towed to mechanic. Diagnosed as probable thermo regulator. Could not repair because part only available from Subaru. Called dealer who was not sympathetic or helpful. Told to bring in and leave. Would get to it when they could.

Check Engine light came on along with EyeSight, traction control and flashing [S] lights. Dealer confirmed that the thermo control valve failed.

When I am idling at a stop sign or sitting in traffic and I have come to a full stop, the car's engine shuts down as a gas-saving feature. This is not the problem! The problem is that sometimes when this feature engages, when I lift my foot off the brake to start driving again, a shrill constant ringing sound starts and the engine won't power back on. There is an error message that comes on that says "eyesight disabled." When this happens, none of these factors (the ringing, the error message, the dead engine) stop until I put the car in park and power it down completely, then restart the engine. Then none of the symptoms are there anymore and the car drives normally. I have not noticed any consistency about when this problem does or does not happen - it occurs in all weather types, temperatures, times of day, slopes/flat roads. I sometimes go months without it happening, and other times it happens twice in several days. The only consistent thing is that it only happens when the car is at a full stop and the engine has shuddered off to save gas. I live in Chicago and almost exclusively drive short distances in the city, I hardly do any highway driving. This has happened maybe 20 times since I bought the car in February, 2023.

My vehicle has repeatedly required being jump-started after sitting for a period of time. Recently it has become a safety issue because the engine is designed to turn off at times in order to traffic to improve fuel efficiency. After research, Subaru has a known issue with the DCM system used to power the optional (subscription based) Starlink system. This system uses 3G signals to provide emergency assistance; however 3G signal has been decommissioned and the system is unable to connect to a tower and never stops trying. This creates a parasitic drain on the battery that can (and has) prevents the car from being able to restart from a stopped position.

Vehicle continuously suffers a total loss of power (engine shuts off) while driving, creating obvious hazard to the user of the car and other drivers. This continues to happen without warning and often while driving through intersections and other dangerous situations. No warning lights precede these events. We brought the vehicle to the Subaru dealership and, after testing/diagnosing the problem, they informed us the vehicle needs a larger battery (which also requires installation of a larger battery tray) than the one that came equipped with the vehicle from the manufacturer. No aftermarket modifications have been made to the battery or electrical systems and the current battery is the size and type recommended by Subaru in the owner’s manual; the dealership, however, advises that that battery is insufficient and needs to be changed for a larger-sized battery.

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 contact owns a 2020 Subaru Forester. The contact stated that the auto START/STOP feature was malfunctioning. The contact stated that upon coming to a complete stop, the engine turned off, but failed to restart after releasing the brake pedal. The message "Engine Disabled" was displayed. The contact depressed the brake pedal and pressed the Push to Start button and was able to continue driving. The contact stated that the failure had been recurring. The dealer was notified of the failure and advised the contact to manually deactivate the auto Start-Stop feature by pressing a button. The contact stated that she followed the dealer's instructions; however, the feature had been engaging independently and the failure had been recurring while at a complete stop. The vehicle was taken to the dealer to be diagnosed. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 39,000.

Mileage: 39,000

Daughter was driving vehicle on the morning of September 15, 2023, when smoke came from under hood. Immediately pulled over and engine was engulfed in flames. Got out of vehicle and moved a safe distance away as glass started to break and fire department arrived on scene. Picked up vehicle on September 12, 2023, after having the thermal control valve replaced (warranty) but after doing research there are other components that also had to be replaced (fuel line, etc) as part of this repair. Noticed there have been other vehicles with recall due to thermal control valve just nothing on the Subaru Forester. Completely traumatized as the vehicle was gone in a little over 3 minutes. Have been in contact with Subaru but no resolution on what they believe caused the car to catch on fire. Did authorize them to get “black box” on September 29, 2023.

I’ve owned my Subaru forester for over a year now. About 6 months ago while getting off an exit and at a light, when I went to accelerate my car died. All lights came off and no power to vehicle. I was able to restart and drive home. Called the dealer took it in and paid almost $2k for repairs. Today the same thing happened on the turnpike in stopped traffic. This could have been a bad accident.

At a stop light, auto stop/start system shuts down the vehicle engine. When the light turned green, and I lifted my foot off the brake, the engine failed to restart. The dash will lit up .. check engine light, eye sight light ... etc will come on. I had to shift to park and restart the engine. I read that low remote battery can be a problem, I replaced the remote battery but it has not resolved the issue. Engine failed to restart at stop light after being shut down by auto stop/start system multiple times in last six month. Only recourse is shift to park and restart the engine. This seems to be manufacture problem with auto stop/start system. It is a safety issue for me and my family having a stalled car at stop light due to engine being shut off by auto stop/start system and failed to restart until put in park and restart it.

The car dies when it stops for a traffic stop. Sometimes it starts again and and sometimes it does not. It does not do it when the air is on. People honk at you in traffic if you do not start right away. I thought there was a recall on Subarus for same which is why I never bought one. The vehicle has been inspected. It also unlocks itself sometimes after I lock it.

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.

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.

While driving the vehicle suddenly stalled and stopped running. The dashboard illuminated with most lights and the check engine message came on the screen. I was thankfully able to get into the shoulder on the road safely without creating an accident or getting injured. The vehicle would not start again and had to be towed to the dealership. I am now out $1800 because I am slightly over my powertrain warranty in mileage on the vehicle. This is a known issue in bulletin: https://static.nhtsa.gov/odi/tsbs/2022/MC-10208664-0001.pdf I am not only disappointed with Subaru of America and NHTSA that this is not already a recall but I am also willing to seek legal action and compensation if this repair is not going to be covered. There are many incidents and reports online of similar issues: https://www.subaruforester.org/threads/2019-thermo-control-valve-assembly-and-warranty-merged-thread.823510/ https://www.carcomplaints.com/Subaru/Forester/2020/drivetrain/power_train.shtml I have filed a case with Subaru of America corporate and am waiting to hear back. Someone is going to cause an accident or end up dead because of this faulty part. It is borderline criminal that this is not already a recall.

The Battery life was considerably short. It started requiring frequent jump starts.

Stopped at a stop light for a few minutes and when trying to move forward the car just stopped working. This happened twice.

The Subaru starlink system has no controls around transfer of ownership. I only discovered this after receiving a $150 charge 2 months after I traded in the car to a Subaru dealer. Even after trading in the car I was able to unlock, lock, start the car, and track the cars location. This represents a significant safety risk to the consumer and must be addressed immediately.

When I was driving this car one night, every dash light was suddenly activated and remained on -- and as a result all safety features were deactivated. When I was able to do so, I touched the battery cables together to reboot the system. I had to do this 3 times over the course of 4 days. Realizing the problem was chronic, I took the car to the dealership (a 2 hour drive), where a service tech explained the problem 'was caused by a low battery.' This car is only 2 years old. A new car battery should last longer than 2 years. It thus seems to me the battery was defective or the car improperly drained it somehow. More important, there is no warning that a 'low battery' -- one which can easily start a car -- could still deactivate safety features while driving.

Engine shuts off when coasting into a turn when car is moving at less than 5mph. Causes loss of steering. Will restart if gas pedal is pumped. Dealer can find no problem. Does not happen predictably and can not always be replicated. Very dangerous.

Repeated experiences of battery going dead after simply opening and closing doors a few times a day for four days. Engine was not started in this time. All interior light were off and rear hatch remained closed. Safety risk is being stranded in rural locations, at times with no cell service. Local Subaru dealer indicated I needed an authorization code from a battery lawsuit settlement to look into it. Lawsuit doesn’t include my vehicle VIN and only reimburses cost for battery replacement and possibly towing, not a repair. Research into the problem has indicated that this “parasitic drain “ can be remedied by replacing the defective older PRG Module with the effective newer one. This should be covered by the warranty on a two year old car. Local dealer would only refer to the lawsuit for direction. Suspect they are “buying time” until warranty expires to avoid doing the appropriate repair. See attached file for example of correct repair from another Subaru owner.

In less than 2 years of owning this car the battery failed putting me in a very dangerous situation. While standing in the middle of the road to make a turn into incoming traffic the car was off because of the auto stop-start system. As I released the brake and tried to accelerate to cross the intersection the car failed to restart automatically and stalled as if the battery did not have enough power. I had to place the car in parking and restart it again in the middle of the road. This happened multiple times. I took the car to the dealer and it was confirmed that the battery was bad and it was replaced. The new battery was good for sometime but lately it feels that it lacks power again, specially to restart when off from the auto start-stop system. This problem is very concerning as it can cause a major accident if unable to restart when expected.

Battery will not hold a charge. Battery frequently needs to be recharged. Bought a portable jumper, to ensure vehicle will start away from home where the battery would otherwise be charged in the garage.

I've owned this car for less than a week and already have to replace a battery that was said to be completely fine. It does not retain charge or replenish when parked.

2nd event - SOY based transmission wiring chewed. TWICE in two years. Car garaged, traps in garage. Our cost: about $1500. Time in shop - 3 months, due to "no parts".

BATTERY DRAINS constantly and car will not start. This has happened several times the past month. I understand that it is an ongoing issue with other Subaru's. This is dangerous and must be fixed. This issue has happened 3 times in 2 weeks. 8/1, 8/13, 8/15/2022

There are various lights on on the dash of the vehicle when nothing is seemingly inherently wrong with the vehicle. I notified the dealership about this issue, the dealership claimed that special parts were ordered but I still have not been notifed of their arrival. This puts my safety at risk due to the fact that I am not sure wether the car actually has an issue, or if it is a mere malfunction. The vechicle is now shaking.

Battery drained, towed to dealership twice within a month battery replaced then failed within 2 weeks everything checked out ok but battery still drained very frustrating

The contact owns a 2020 Subaru Forester. The contact stated that the battery was continually being drained and needed to be recharged frequently. There were no warning lights illuminated. The vehicle was taken to the local dealer however, a cause for the failure was not determined. The dealer recharged the battery. The vehicle was not repaired. The contact related the failure with electrical system defects which consistently drained the battery. The contact recharged the battery after each time the vehicle was driven. The manufacturer was not notified of the failure. The approximate failure mileage was 2,000.

Mileage: 2,000

Battery constantly dying. Significant safety concern. Never no when the car is going to not start. Unreliable

Electrical defect in recent Subarus causes parasitic battery drain when the car is not in use. Our battery drained to the point that the vehicle couldn’t start without a jump due to this defect.

The battery drains regularly, causing the vehicle to be inoperable. Battery is dead after 3 days of non use, leaving vehicle unable to be used.

The contact owns a 2020 Subaru Forester. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed; however, the vehicle failed to respond. The vehicle stalled and then went into sleep mode. The contact was able to restart the vehicle after several attempts. There were several unknown warning lights illuminated. The contact stated that the vehicle also experienced failures with the electrical system. The vehicle was taken to the local dealer where the contact was informed that the vehicle was operating as designed. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 1,300.

Mileage: 1,300

At the time,time, car was not fully 2 years old.. its brand new.This is an addition to a post created a week ago. After the dealership offered to detail the interior of the car to solve the sulferic acid feeling I noticed that the flap above the driving wheel started to feel warm. This happened right in the morning in February. I'm not sure if I am feeling an electrical voltage, smelling the exhaust or there's still sulferic acid in the car. Every once in awhile I my hair smells like oil.. Whatever it is it makes your head feel heavy. My toddler feels something because during a drive he will say " hot". This puts our safety at risk if we are smelling the exhaust or feeling voltage while driving in the car. Sometimes it smells like fuel I the trunk of the car or acidic

Battery draining requiring multiple charging.

The battery died after less than two years. There is a class action lawsuit related to recent Subarus draining batteries very quickly due to parasitic power drain because of a faulty electrical system. The 2020 Forester was included in the initial lawsuit, but this model was thrown out of the lawsuit by the judge since none of the plaintiffs owned a Forester. However, it is a known issue. Prematurely and unexpectedly dead batteries, as I experienced, can cause motorists to be stranded and face related hazards, as well as to incur unexpected costs. I spent more than $200 to replace my battery long before the minimum expected three-year battery life.

I bought my new 2020 Forester in November 2019. It now has 1604 miles on it. Twice already I've had to have it towed to the dealership because the battery was dead from just sitting in my driveway. The first time, February 2021, they said it was a bad battery. The second time, January 2022, they said it's because I don't drive the car enough. Said I have to drive or idle the car for at least 15 minutes twice per week which is a waste of gas and time for something that shouldn't happen to start with! There are already lawsuits about this constant battery drain but the 2020 Forester isn't included and it should be! There is NO reason for the battery to constantly drain to the point that the car won't start when the car is sitting with everything turned off!

The contact owns a 2020 Subaru Forester. The contact stated that while driving at an undisclosed speed, the radio system malfunctioned, which caused the blind-spot detection system, headlights, and instrument panel to fail to operate as needed. Additionally, the eyesight system would inadvertently engage, which caused the vehicle to stop without warning. The contact restarted the vehicle to correct the failure. The vehicle was taken to the dealer, and AutoNation Subaru Scottsdale (15678 N Northsight Blvd, Scottsdale, AZ 85260) and diagnosed with radio software failure. The dealer replaced the radio on three separate occasions; however, the failure recurred. The dealer also reconnected the eyesight system and resolved the eyesight system failure. The manufacturer was made aware of the failure. The failure mileage was approximately 1,000.

Frequent battery dying problem in 2020 Subaru Forester from Grayson Subaru, Knoxville, TN I am a 67 year old woman who does much scientific research in remote places alone at night. During the day, I manage 3 farms 100 miles apart. I am constantly opening and closing gates, getting out briefly to check livestock and fix fences. If my keys are left in the ignition even briefly, as I get in an out for small tasks, the car battery is dead. Other times it is simply dead for no reason at all. In my over 50 years of driving all sorts of cars and trucks, I have never had this problem. I have had constant problems with this car battery dying in as little as 5 minutes after driving 50 miles. I have brought this problem to Grayson Subaru’s attention and spent hours waiting as they checked for problems. They never find anything. I have made numerous calls. They assure me this is “normal”. This is NOT normal. Not in my over 50 years of driving cars. I am forced to carry a car booster with me at all times. This is a TERRIBLE situation for a car which typically is owned by people who often camp, are doing sports in remote places or need a small rugged car for farm work or field research or outdoor activities. Here are just a few times I have contacted Grayson Subaru over this problem. I have had dead battery many more times than this (just in past 2 weeks Jan 5, 10 and 14, 2022), but have had to jump it off because I was in a dangerous. I bought the car in Sept 2021 from Grayson as a new car: Calls and visits to Grayson over the battery problem. Jan 22, 2021; August 11, 2021; Aug 23, 2021; Aug 24, 2021; Oct 5, 2021; Nov 17, 2021; Jan 11, 2022. I do not want to invoke the Tennessee Lemon Law (T.C.A. 55-24-101 to T.C.A. 55-24-112), but I also cannot continue to drive such an unreliable car. I see there is a “battery drain" lawsuit for 2020 Subaru Foresters. I believe this car has the same problem. What do I do?

The contact owns a 2020 Subaru Forester. The contact stated that the battery drained quickly, and the vehicle had to be jumpstarted after three days. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 2,000.

Liftgate open for tailgating party. Battery drained despite NO lights being on at all. This should NOT happen. Left me (50yo woman) and 3 kids stranded in a very bad part of town.

I was in a parking lot at the time driving very slowly to pick a spot. When I went to turn right into the spot my car accelerated at an alarming speed. I had not control over it as it kept turning. It hit the car parked in front of my space pushing it and went on to hit the car parked to the right damaging both the front left and right sides of my vehicle and the 2 parked cars before coming to a stop. Fortunately it was 9am and not very crowded, there were no passengers in both vehicles and no one walking in between or by the cars which could have been tragic. I was wearing a seatbelt. The police were called and completed a report. The Subaru dealership was called and Subaru of America was called. The car was inspected by a Bosch.-EAA representative for Subaru on 8/4/2021. I have not heard back from Subaru so far although I was told it could take several weeks. There were no warning lights prior to the incident but afterwards there were several warning lights on. A few months before I got into my car and the radio was blaring and constantly switching channels and I was not able to turn the radio off. When I got home and turned off the car and turned the ignition back on 30 minutes later it had stopped. We notified the incident to Subaru at the next oil change. I immediately notified USSA car insurance and filed a claim. I have not had the damages assessed for repair because I have to wait for the inspection results from Subaru. I felt it was important to document this incident in case other 2020 Forester owners have experienced the same thing. Frightening.

Purchased new on 5/22/2020. On Aug 8th after not driving the car for 3 days, attempted to start vehicle. Would not start. Battery dead. Charged battery with a jump. Drove car home. Next am. Car would not start. Battery dead. Currently trying to get car in for service. This is very dangerous stranding people randomly.

The battery on my 2020 Subaru Forester Premium /LFF14 drains within a week if not driven. There appears to be a parasitic battery drain problem. The car will not start. I replaced the original factory battery with a larger, after-market battery having been told by several sources that this problem is common to Foresters and is caused by defective batteries being supplied to Subaru. However, the new battery did not solve the problem. I regularly test the battery with a battery tester that indicates that the battery is OK, but is discharged and requires charging. I now keep a trickle charger on the car continuously. This seems to keep the battery charge up to 98%. I have retained the original battery which holds a charge indefinitely out of the vehicle. I am aware that driving the car to recharge the battery is extremely hard on the alternator and will cause it to prematurely fail. The car was purchased in August of 2020 and currently has less than 500 miles. This is a recurrent problem.

My car shut down while stopped at a traffic light. Several dashboard lights flashed or lit up, including the battery indicator, the EyeSight indicator said it was turned off, and many others I don’t know. It felt as if the battery had died. The car was in standby mode while stopped and the air conditioning was running. The car stalled and died when I took my foot off the brake to drive. The battery has died 6 times in the past year. If the door was ajar, the hatch left open, or the engine turned off while parked in drive, the battery was dead the next day. If it’s left overnight with the emergency flashers on, the battery is dead the next day. This is too many for a brand new car. I’ve already bought a brand new battery after the first one died. What do I have to do to keep the battery alive? I’m a Lyft driver, and thankful this issue didn’t leave a rider and me stranded many miles from home.

I tried to unlock my car but the remote didnt work- I had to use the blank key inside the remote to get in the car. I couldn't start the car- my husband tried to jump it- that did not work- I called AAA they tried jumping it - that didnt work-- AAA told me the battery was good but totally out of charge 0%-- I called the subaru salesman I bought the car from & he walked me thru alot of steps & we couldn't find anything wrong besides the battery!! he told me to have my husband try to give me a jump again & after 4 hours the car turned over! What caused it????? no idea??? the next day (7/5/21) I took it to an auto parts store & they tested it out- alternator-perfect--- battery @ 550 with the max 620--- today I read an article about Subaru batteries failing! well mine did for no apparent reason--- maybe they should all be recalled!! I missed my 1st day of vacation due to this!!

Battery is completely drained and I was unable to commute. Vehicle picked by Subaru roadside assistance to nearest dealer (Victor Subaru)

What component or system failed or malfunctioned, and is it available for inspection upon request? - The original battery on our 2020 Subaru Forester died after some repairs related to getting rear ended. The battery died for the first time in March 2021, 8 months after we purchased the car with around 5500 miles on it. That battery was replaced with a brand new Subaru battery. The battery has died 3 times since being replaced. The current battery is available for inspection. In addition to the battery dying, we have recently noticed two situations where the rear hatch has not properly latched. I have a video of the rear hatch trying to latch and popping back open over and over again. I've only noticed this twice, but the first time I noticed this I realize we had been driving with the rear hatch open and our dog could have been put in serious risk if the rear hatch opened. How was your safety or the safety of others put at risk? Issues with the battery dying multiple times puts me at risk of being stranded. The issue of the rear hatch means that anything that is placed in the rear of the vehicle may not be properly secured and could potentially fly out of the vehicle if the unlatched rear hatch opens while driving. Has the problem been reproduced or confirmed by a dealer or independent service center? The original dead battery was initially identified by a body shop. The dealer was not able to find anything wrong with the vehicle upon first inspection, but we are going to take it in again. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle was inspected by a body shop (recommended by our insurance) and the dealer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The only symptom we are able to routinely detect is a low voltage on our battery, which we believe indicates a parasitic draw.

BATTERY WAS DRAINED FOR NO REASON AND CAR WOULD NOT START. WHEN TRIED TO START DASH LIGHTS ETC., WENT CRAZY. GAUGE FOR TACHOMETER AND SPEED WHIPPED FROM SIDE TO SIDE, LIGHTS FLASHED ON AND OFF. THE STARTER GAVE THE CLICKING NOISE YOU HEAR WHEN BATTERY IS DEAD. CALLED AAA TO JUMP AND THEY COULD NOT GET IT TO START. I CHARGED BATTERY OVERNIGHT AND THE ENGINE STARTED. TOOK CAR TO DEALER THEY COULD FIND NOTHING WRONG WITH THE BATTERY OR CHARGING SYSTEM. THEY COULD NOT EXPLAIN WHY THIS HAPPENED. I PURCHASED A BATTERY TENDER TO MAINTAIN CHARGE IN BATTERY.

WHEN ATTEMPTING TO LEAVE OUR HOME DRIVEWAY ON FRIDAY, APRIL 2ND, 2021 (APPROXIMATELY 4PM LOCAL TIME), THE IGNITION BUTTON FAILED TO START THE CAR. INITIALLY, POWER WAS RUNNING TO THE DASH. I CALLED THE SUBARU EASTSIDE DEALERSHIP IN KIRKLAND, WA WHERE THE CAR WAS PURCHASED. THEY TOLD ME TO CALL ROADSIDE ASSISTANCE, WHICH I DID THE FOLLOWING MORNING. WHEN MY WIFE AND I MOVED OUR CAR SEAT AND BELONGINGS TO THE OTHER CAR IN THE DRIVEWAY, THE REAR LIFT GATE STARTED TO MALFUNCTION AND WOULD NOT OPEN (RESULTING IN A REPEATED 3 BEEP SOUND), BLOCKING ACCESS TO MY JUMPER CABLES, WHICH WERE IN THE TRUNK. EVENTUALLY, THE ELECTRICAL SYSTEM STOPPED RESPONDING ALL TOGETHER. WHEN ROADSIDE ASSISTANCE (SENT OUT BY SUBARU ROADSIDE) EVENTUALLY SHOWED UP THE FOLLOWING MORNING, A JUMP START BY THE TECHNICIAN STARTED THE VEHICLE.

A CHANGE IN SOME 2019-2020 SUBARU MODELS CAUSES AN INCOMPATIBILITY BETWEEN OBD-II DEVICES AND THE SUBARU STARLINK SYSTEM (WHICH IS USED TO DISPATCH EMERGENCY SERVICES IN THE EVENT OF AN ACCIDENT, AND FOR OTHER PURPOSES). SUBARU SERVICE BULLETIN 15-257-19 11/11/2019 RECOGNIZES THE PROBLEM, BUT DOES NOT OFFER A SOLUTION OTHER THAN TELL THE CUSTOMER NOT TO USE THE OBD-II DEVICE. SINCE THE STARLINK SYSTEM PRIOR TO MODEL YEAR 2019 WAS COMPATIBLE WITH OBD-II DEVICES, IT SEEMS LIKELY THAT A SUBARU INITIATED CHANGE IS CAUSING THIS INCOMPATIBILITY. AS STATED IN THE BULLETIN, IN ORDER TO AVOID HAVING THE CAR NOTIFY THE DEALER EVERY 3 DAYS OF THE PROBLEM, THEY HAVE CHANGED THE NOTIFICATIONS TO ONCE EVERY 10 DAYS. THIS IS NOT SOLVING THE PROBLEM, BUT MERELY PUSHING IT DOWN THE ROAD. SOME CONSIDER STARLINK A SAFETY SYSTEM, AND PAY EXTRA TO HAVE IT AVAILABLE. COPY OF SERVICE BULLETIN ATTACHED. THIS IS A CONTINUING, REPEATED PROBLEM STARTING ON 3/11/2020 AND IS A CONTINUING INTERMITTENT PROBLEM. FIRST DEALER SERVICE ON 3/17/2020 FOUND NO PROBLEM BECAUSE THE ISSUE HAD TEMPORARILY RESOLVED ITSELF. THE SERVICE BULLETIN WAS NOT FOUND BY THE OWNER UNTIL 4/2/2020 AFTER SEVERAL BACK AND FORTH EMAILS WITH SUBARU CUSTOMER SERVICE BEFORE THEN.

VEHICLE IGNITION IS OFF AND IN PARK. THE SAFETY ISSUE OCCURS WHEN THE REAR TAILGATE IS LEFT OPEN. AFTER 20 MINUTES OF LEAVING THE REAR TAILGATE OPEN, ALL THE INTERIOR LIGHTS TURN OFF CORRECTLY AS A PUBLISHED SAFETY FEATURE TO HELP PREVENT A DEAD BATTERY UPON DEPARTURE. THE USER THINKS EVERYTHING HAS SHUT OFF WHEN THE LIGHTS TURN OFF, HOWEVER, THE REAR TAILGATE ECU DOES NOT TURN OFF OR GO TO A LOW POWER STATE AFTER THE INITIAL 20 MINUTES CAUSING A HIGH DRAIN ON THE BATTERY. THE HATCH ECU CONTINUES TO DRAW IN EXCESS OF 4 AMPS WHILE THE HATCH IS LEFT OPEN, CAUSING A DEAD BATTERY IN AS LITTLE AS A FEW HOURS. THE USER CAN UNKNOWINGLY BE LEFT STRANDED WITH A DEAD BATTERY CAUSING A SAFETY ISSUE. THIS IS A SERIOUS OVERSIGHT AND ENGINEERING ERROR THAT WILL LIKELY LEAVE MANY PEOPLE UNKNOWINGLY STRANDED WITH A DEAD BATTERY.
