Electrical System Problems of Subaru Forester - part 1

The defect presents itself when the equipped data communications module (dcm) attempts to communicate with 3g cellular networks. As 3g networks within the u. S. Are no longer functioning, the call will continuously fail even after the vehicle has been turned off, draining the battery and resulting in a no-start safety risk for drivers.

Previous recall for passenger ods. Having continued issues with passenger airbag ods not recognizing someone sitting there. Intermittently turns on and off even if no one is sitting there. Took it to a dealer and they want me to pay out of pocket for diagnostic and possible parts. Very high concern for even allowing someone to sit in the car (even my pregnant wife) in the case there was ever an accident.

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 vehicle has experienced four separate engine shutdowns while stopped in traffic. Each time, the engine turned off unexpectedly, requiring a manual restart. One incident occurred near a railroad crossing with my child in the car. The vehicle also lurches forward at low speeds and hesitates when accelerating after being stopped. These issues persist despite service visits. I believe they may relate to technical service bulletins regarding the auto start/stop and battery systems (tsbs #16-147-24, #10232217, #07-218-23r, #10251098). Subaru service staff have acknowledged awareness of these problems. I’m submitting this complaint to ensure the safety risk is documented and investigated.

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.

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.

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.

We were traveling in rural California, 1 hour north of bishop, CA on CA-120 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.

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.

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.

- *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:* - 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.

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.

Vehicle self-accelerated abruptly while parked and crashed into another vehicle causing damage to both vehicles.

Parasitic battery drain.

I am writing to report a serious safety concern involving my '22 Subaru Forester, which is equipped with the auto start/stop feature. This issue created a dangerous driving situation that could have resulted in severe injury or death to myself, my family, or other drivers on the road. While driving on the highway, our Forester's auto start/stop system malfunctioned causing the engine to shut off completely while the vehicle. Specifically, the vehicle shut down in the left lane of traffic and failed to restart immediately leaving us unexpectedly immobile. Fortunately, my husband remained calm and immediately placed his foot back on the brake, placed the vehicle in park and restarted the vehicle manually by pressing the ignition button. However, had he hesitated during the confusion by not placing his foot back on the brake we could have been rear-ended, possibly by a large semi-truck which would have propelled us into the vehicle in front of us. Our dealer said the auto start/stop system failing to restart the vehicle due to a weakening battery—for which there is no warning. The fact that a non-critical feature like fuel-saving start/stop is allowed to override the engine's operability based on battery voltage is deeply concerning. Batteries degrade over time. But a degraded battery should not be allowed to disable a moving vehicle. Having spoken directly with Subaru of America about this issue, they acknowledged and documented my case however I was told that it would be used as data for potential future action if other similar cases arise. In the meantime, no corrective action is being taken by Subaru, with me as an owner or proactively with the feature design. I respectfully urge the NHTSA to investigate this matter as a potential safety defect. The auto start/stop system, as implemented in certainsubaru models (specifically the 2022 Forester in my case) may compromise safe vehicle operation when battery voltage drops below a certain threshold which is a safety flaw.

After arriving home from a short drive to the grocery store I parked my car in the drive way and went inside. On the drive home I could hear a low humming coming from the speakers and the car was decelerating when the accelerator was not being pressed, no warning lights or sounds came on. About 10 minutes after I parked a neighbor knocked on the door letting me know my car was smoking from inside the hood. Within a minute or 2 the entire hood of the car was engulfed in flames. The entire front half of the car burned to a crisp, the fire also burned half a tree. The car was burning so hot that it melted the hood of the car, had I parked it with the hood facing my house my house would have caught fire. The problem has not been reduced or confirmed by dealer or independent service. The vehicle is being stored by the insurance and for the time being is accessible for investigation. Because I was having trouble with the infotainment system, the humming coming from the speakers, and a recent warranty extension by from Subaru for the infotainment system due to known issues I suspect that the fire was caused by electrical issues.

I’m facing a really big issue here. I’ve been experiencing all the textbook issues in my vehicle for both of the recalls that did exist for my vehicle. I purchased my vehicle in [xxx], and I was just in to walser Subaru in st. Paul mn where they said my recalls were completed in April 22, 2022. That is absolutely not true. I was at the dealership all day that day. So I called miller hill Subaru in duluth mn where it said it was done, and all they provided me with was the 2 dates I had brought it in for a general inspection and for an a/c issue. All I had done there was a transmission flush and both of those times were well after April 22nd. I purchased my vehicle from anderson auto in rice lake township. So now I have my car with recalls that were falsified that they were done, but I am expected to pay for them. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Driving on the garden state parkway in NJ on August 1st at approximately 1pm my car just stopped in traffic and steering locked up and all lights came on dashboard along with a constant beeping sound-I was in the middle of a four lane highway traveling south-I could not get out of my car and feared someone would hit me as I was a "sitting duck" while cars were swerving around me-my only saving grace was that my flashers worked after I turned them on-I called roadside assistance as I was starting to panic and was told they could not help me as I was on a private road-I saw a helicopter overhead and at the same time a police office weaving in and out of traffic behind me to slow and stop the traffic-he then proceeded to push my car off the road with his car to the shoulder and called a tow truck-car was towed to nearest Subaru dealer where they performed a diagnostic test and found nothing wrong with my car!! how could that be?? I was then charged for the test and the tow-have called Subaru customer care several times but they say they cannot help me because the test result showed nothing-please help me as I no longer have peace of mind driving this vehicle and I am a single woman in my 70's who needs to drive long distances several times a month- there were no previous warnings in my car it just stopped.

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.

Yesterday 6/19/25 I was driving out the driveway when the vehicle accelerated on its own, and not slowly, but like it had been punched. I was actually coasting at the time since I didn't want to stir up dust. My foot was not on the gas pedal. And it was not the floor mat. It happened on its own, the first time in 87,000 miles. It probably cannot easily be replicated as it was completely random, although now that it's happened once, it very well could happen again if there's a faulty or aging part or sensor. Neither the local dealer nor Subaru has acknowledged the problem (I called both today) but it's a serious safety issue. No check engine light or other means of warning. It just happened out of nowhere. Glad I was in the driveway and not in town waiting while a pedestrian was crossing the street.

The rear backup camera failed. No warning lights appeared. This is a safety issue. This repair was expensive should not have happened at 79019 miles. The problem was inspected and estimated by our Subaru dealer. We were told that the radio/screen unit first needed replacement, then if that didn't fix it, to then replace the camera. We were give a rough estimate of $2500 to replace both items. We decided to get another estimate. They determine it was the camera, which we had them replace.

The passenger airbag sensor often, but not always, malfunctions in my 2017 Subaru forrester. Often it says passenger airbag off when there is a passanger. Occording to kbb kelly blue book there is a current recall in place for 2017 Subaru forresters for exactly this issue, including for my car - but when I typed in my liscnese plate in the NHTSA website, no unrepaired recalls showed up for my car.

My vehicle is equipped with automatic start/stop system. In early 2024, I began having issues with sluggish restart during the start/stop cycle. I took it into the dealer at that time, who stated it required a software update and charged the battery. The issue persisted. It was more serious, as it was not just sluggish on the restart, but the restart would fail and stall the car. This happened in heavy traffic, which was very scary and unsafe. I took the vehicle back into the dealer in late 2024 for the same issue. They did another software update and charged the battery again. They recommended that we purchase a new battery. One month later, we purchased an upgraded agm battery, as it was recommended for auto start/stop systems. The issue continued to persist. First, with sluggish restart. Later, the auto start/stop system failed again in heavy traffic. We took the vehicle in again, and again the dealer stated it was the battery. They recommended we purchase a new battery. It was explained the battery was 6 months old, and the issue has never been fixed. Further, it was pointed out that the car could be restarted manually with the push button ignition, after a start/stop system failure. That led us to believe it was not a battery failure, but a deeper system failure. The dealer continues to assert it is the battery, even though it happened with a factory battery and a new, upgraded, battery. Neither of the batteries have failed testing, and report as "good" on the diagnosis forms. We believe there is a system issue, that is causing issues with the auto start/stop system, and is not being identified by the dealer. It is a safety issue, as it has happened in heavy traffic several times. We have attached diagnostic reports from March 2024 and June 2025, but cannot find the October 2024 diagnostic report.

Without any prior issue of having the engine turnover from being parked for more than 20 hours, the car would not start. It’s like the battery completely died overnight. I was able to unlock it but the car would not start, and therefore was unable to go into neutral because I didn’t have a long enough screwdriver with me to manually override into neutral. So it had to be jumped partially to be towed (had it towed for more than just the battery because it’s under warranty). The interesting part is that my car has a factory issued battery, and my car was the third Subaru made after 2020 that had to be towed due to the same issue, in the same day. Maybe the batteries are defective? regardless, since everything relies on power now, having a provided device to allow for manual override would prevent folks from being stranded. I tried using my key and the screwdriver that comes with the spare tire. Both were to short.

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 2025 Subaru Forester hybrid. The contact stated that the hatchback had opened independently while the vehicle was parked. The contact stated that the doors had opened unintendedly while the vehicle was being washed at the car wash. The contact stated that the door required to be slammed to close and to latch securely. Additionally, the contact stated that while reversing out of a 2-15 percent sloped driveway, the reverse automatic braking (rab) system's beeping sound engaged while there were no vehicles or objects in the proximity of the vehicle. The contact stated that the vehicle stopped abruptly, causing the driver's side seat headrest to hit the contact's head violently. The contact stated that the vehicle became inoperable. The contact exited and inspected the surroundings of the vehicle. The contact verified that the vehicle had not collided with an object. The contact returned inside the vehicle, and the vehicle responded as needed. The contact pulled into the driveway. The contact contacted the doctor's office weeks later, and was referred to the er. The contact went to the er, where a CT scan, and other tests were performed, but internal bleeding was not found. The contact sustained a concussion and persistent headaches. Additionally, the contact underwent an mri and was waiting for the neurologist to interpret the mri test results. The vehicle was taken to the dealer, where the contact was advised to deactivate the reverse automatic braking(rab) system. The manufacturer was notified of the failure and sent a field technician who inspected and test-drove the vehicle. The manufacturer later informed the contact that the vehicle had operated as designed while reversing on the sloped driveway. The vehicle was not repaired. The failure mileage was approximately 100.

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.

Currently suspected that the vehicle battery was installed incorrectly during assembly. Engine fire started at the battery wiring and vehicle was a total liss.

I’ve experienced recurrent failures with my Subaru’s ac system, and it’s become more than just an inconvenience—it’s a real safety concern. In hot weather, the cabin can become unbearably warm, making it difficult to concentrate and increasing the risk of fatigue or even heat-related illness, especially for passengers who are older, very young, or have medical conditions. What’s even more frustrating is the poor quality of the system and Subaru’s lack of communication about what appears to be a known defect. Despite numerous complaints from other owners and repeated service visits, there’s been no clear explanation or long-term fix offered. The situation is not only uncomfortable—it’s unsafe, and the lack of transparency and accountability from Subaru has been incredibly disappointing.

While I was driving to work, with cruise control set at 65, I hit a deer head on. All airbags deployed and engine ceased and I was able to brake car to a stop on the shoulder of the road. Within minutes, the engine erupted in fire and thankfully I wasn't trapped inside and was able to get out, because by the time I got 4-500 feet from the car, it had been totally engulfed in flames. From the time I hit the deer to the fire starting was less than 10 minutes. Fire truck wasn't even on scene yet and I was still speaking with highway patrol on the phone. If I had been trapped or the vehicle had rolled I wouldn't be here today. It was that quick.

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 airbag sensor (ods) malfunctions for front passenger seat. The "airbag off" warning lights up when the seat is occupied. This was fixed by dealer back in 2020 under recall wum-98/NHTSA id 19v-701000. However, this problem recurred intermittently about five months ago. I called capitol Subaru in san jose, CA and spoke with service advisor, dan padilla, who informed me that the recurrence of this safety issue would no longer be covered under this recall. He offered to schedule an appointment for a diagnosis, but I declined since it would cost $300. I also spoke with jorge, case specialist, from Subaru of America who reiterated that the aforementioned recall only covers a one-time repair and cannot be reopened. It is my understanding that safety recalls do not expire and that "federal law often mandates the manufacturer to provide free repairs for safety recalls on vehicles up to 15 yrs old. " how can NHTSA help in resolving this car safety issue with Subaru? the ods system is unreliable and poses a risk to my passengers.

The battery is getting drained by the car's system.
