Electrical System Problems of Subaru Forester - part 2

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.

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 freeway for about 25 miles. The next day drove to and home from work (25 miles reach way) with no issues. The following day, my car wouldn't start from my home. Jumpstarted with the manual one and brought it to the shop a few miles away. Got to the shop and turned off the engine. When turning on again, it wouldn't start.

My 2021 Subaru Forester battery has died twice in the last 10 months. I could not jump start the vehicle the first time about 10 months ago. I needed aaa to jump start it. I took the car to the dealer; they recharged the vehicle and said the battery was fine. They did not bill me. The car died again this week. This time I was able to jump start the vehicle myself. The safety issue is I might need to get to a doctor's appointment or other emergency in a hurry. I may be out shopping or hiking and need to return home, perhaps in bad weather. I might be stranded in a busy intersection or a lonely country road. The battery is simply not trust-worthy. The vehicle was inspected by the dealer, and they said the battery was fine. There was no warning lamp before the battery failed. The car is not safe-I don't know when it won't work.

I was stopped at a red light when, suddenly, my car engine completely shut down, a loud and high-pitched alarm began to squeal and many alerts flashed on my screen. One of the alerts stated that the eye--sight was not functioning. The car would not move when the traffic light turned green and I applied the gas pedal. Cars behind me and those in oncoming traffic had to swerve around me. I was in the center lane of traffic. Fortunately, I was able to put the emergency blinkers on. The traffic light turned red again. It occurred to me to shift into park and attempt to restart the car. The car did restart and I was able to drive home when the traffic light again turned green. I made an appointment to take the car into concordville Subaru and, there, I was told that the battery was low and I was given a new battery since the car is under warranty. I am reading from other owners that this is a temporary fix only and that it does not address the real problem.

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.

[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 pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My dealer diagnosed issues with my car the gasket around my sunroof failed and allowed water to infiltrate the cabin and the electrical system over time. This caused corrosion in the electrical harness, which caused battery failure, failure of the adaptive headlight system, and random electrical glitches. My interpretation of their diagnosis was that this was a cascading failure that might have led to problems with other electrical components such as power brakes, other adaptive systems, etc. , and affected safety, if it had not been diagnosed in time. An insurance appraiser confirmed the dealer's diagnosis. Repairs (including replacing the electrical harness) have been completed and so the situation is not available for further inspection. When the adaptive headlight system stopped working, this was reported on the dashboard, but the cause of this and the base problem was not.

12/14/24-I was stopped at a red light at a very busy intersection. The engine was in stop mode by the start/stop feature. When the light turned green, the car failed to start. The entire car shut down, with alarms sounding and dash lights flashing. The entire system had to reboot before I could restart the car. It was a freighting experience. Fortunately, I wasn't killed by traffic zooming by or by some person with road rage. 12/16/24-issue evaluated by local Subaru dealer. Their evaluation was that when the auto start feature was activated, my car battery was too low to work. There was zero warning about a low battery before this failure in traffic. I had to buy a new battery. The auto start/stop feature is not an enhancement, but a safety hazard. Owners should be able to permanently disable this unnecessary drain on batteries and starters. I did a search, and there are plenty of others that experienced similar issues with their Subarus.

The wum-98 recall fix did not address the problem with the front passenger occupancy detection system. We, and many other Subaru Forester owners are continuing to experience problems post recall repair with the srs airbag light on, indicating error code b1760 "occupant detection sensor mat" failure. Subaru is not covering the cost of addressing this problem, and the entire seat frame and bottom cushion (that includes the sensor mat) are required to be replaced at the consumer's expense, with bills for repair in excess of $2,000. And, due to the high demand for this repair, parts are not available to perform the repair for as much as 6 months! this is jeopardizing the safety of occupants in the front passenger seat for extended periods of time while waiting for parts, whereby the airbag is not active due to the sensor mat problem. The original recall should have encompassed not only the harness cable component, but also the sensor mat.

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.

1. The car shut off several times, with the steering wheel locking up and becoming stiff, the brakes failing to respond, and loud, erratic sounds emanating from the vehicle. The car is available for inspection. 2. Yes, the car crashed resulting in damage to the car, driver, and other driver (e. G. Car in front). 3. This is the second time the car has been brought to the dealership (the second time being Subaru south hill in pennsylvania) and they cannot identify the problem. 4. The vehicle was not inspected by police, or insurance, as far as I am aware. 5. There were no warning signs before the failure.

I had a problem. Arming the remote control. With Forester Subaru 2014 -2015 model car w/n arm. With key or electronically. I had changed battery you can arm manually sometimes , alarm will go off if you use the key to open door and shut it off with key. In ignition. Had a diagnostic test done. With code b1500. Tpms lights stays on also. Tires are good. Pressure good. Extra remote key is good batteries changed. Any info concerning this. Thank you. This happen week and half ago Nov 11,2024. Have an appt will Subaru dealer on Dec 5 to toubleshoot. Is there any recalls for this matter.

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!.

My backup camera would not operate after washing my car. When I was backing up, I got an alert that something was in my way. There was no picture, so I could not see what it was. I had to stop and get out to see. This could lead to serious problems, like getting hit by other vehicles while have to get out and look for obstacle. This could also be a risk to children crossing behind the car, because eventually the driver will tire of getting out and walking around the car. When I went to take the vehicle to the dealer the next day, the car had dried off, and the camera came back on. I looked at other Subaru forums and found many NHTSA recalls on cameras on different year Subaru's. The problem still seems to persist on my model, but no recall.

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.

The automatic shutoff that occurs when the vehicle stops to prevent idling, disengaged two separate times in the span of 4 days. Both incidents occurred at very busy intersections and failed to restart both times. When attempting to restart the car, lights came up on the dash, along with beeping, and failed to restart the car after the light had turned green. To restart, the car had to be completely turned off for about 60 seconds and then could be restarted. To avoid having to experience this issue again, or worse - get into an accident - I took it to the shop where they could not recreate the issue.

The contact owns a 2021 Subaru Forester. The contact stated that while waiting at a traffic light, the accelerator pedal was depressed, and the vehicle immediately shut off. During the failure, the message "eyesight disabled" was displayed and the vehicle could not immediately be restarted. The gear shifter was shifted to neutral(n) and the vehicle was pushed to the side of the roadway. The vehicle was eventually restarted and operated normally. The cause of the failure was not yet determined. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was 37,000. The VIN was not available.

The key keeps getting stuck in the ignition. . . . . . . . .

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.

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).

Passenger's seat belt sensor is alarming when no one is in the seat. The passenger side airbag warning light is also coming on and off. I took it to the dealer, and they confirmed that the sensor in the seat pad is bad. The airbag light was intermittently going on for several weeks before I took it in. The car has been at the dealer since mid-August, and I am told that the part is currently on backorder without an estimated arrival date.

I bought the car certified used from a grand prix Subaru in hicksville, NY. They did not mention this issue. I’ve had the car for 2 years, drive it 1-2x a week, have it serviced regularly, etc. All of a sudden in the past week it’s needed a jump 2x, maybe a few days apart. My lights are on auto, always, & shut off when the car turns off after a few seconds. My interior lights are all set to off, after the first jump. Doors & cargo door are all closed well. Battery has been tested & they say it’s not bad & doesn’t need replacing. So what is draining the battery then? when the battery is dead, it’s completely dead. No turnover at all & the cargo door won’t open until it’s running & charged enough again. I’m shocked the cargo door can’t open without the battery!.

My 2018 Subaru Forester has a faulty passenger air bag sensor, which has been diagnosed by my local Subaru dealer, with a repair cost of $1,500+ for labor and parts. It has intermittently turned on and off again, but after getting a separate issue fixed by my dealer, they diagnosed this problem, and every time the car is turned on, the warning light is constantly displayed, and the passenger seat airbag light shows "off" even when someone is in the passenger seat. Upon research, this is a known and common issue with other Subaru Foresters with heated seats in the same model year (my Forester does have heated seats), but my VIN is not included in the Subaru recall for this specific repair. This greatly puts the passenger in my car at risk, as the sensor does not recognize that a person is in the seat while they are riding, and if we were to be in an accident, their airbag would not deploy. I am frustrated that this is a known, common safety issue that affects my model and year of car, but my VIN is not included on the recall list. I would expect that my car should also be included in the recall and fixed by the dealer at their expense as it is clearly documented many times on other 2018 Subaru Foresters.

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.

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.

113,727 miles. 2016 Subaru Forester. 5 different warning lights all came on at the same time. Before that I noticed occasionally there was a delay starting again at a stoplight. Reputable mechanic replaced the valve body of the transmission. They said they service 2-3 Subarus for this same issue every month.

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?.

Blind spot detection goes on an off. Safety is impacted by the system going on and off. Took care to Subaru dealership.

Starting up the car in the morning after a long day stuck in traffic (over 100 degree f weather), moved about 5 feet then the eyesight system stopped working, rear braking stopped, and power steering gave out - the car started and the engine ran normally. The car was abandoned as unsafe until diagnostics could be performed and a different car was used to get around . That evening the car started up fine, also the next morning to reproduce conditions. Tested the battery, which showed "good" (93% charge/40%healthy). I suspect that, in the morning the a/c, headlights, radio, backup lights, etc. . . Put a large draw on the electrical system resulting in a system wide shutdown of adaptive features - however loss of power steering is insane and can easily result in death if it happens while driving especially while making a turn if the driver is not prepared/strong enough to force it. The linking of non-critical system to help the driver to an essential system is just asking for trouble.

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. Photos attached.

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.

Vehicle: 2024 Subaru Forester touring date of report: [July 3, 2024] what component or system failed or malfunctioned, and is it available for inspection upon request? on June 19th, 2024 I noticed the side mirror of my 2024 Subaru Forester touring has melted. This component is available for inspection upon request. How was your safety or the safety of others put at risk? the melting of the side mirror poses a potential risk of fire if it continues to deteriorate. This not only endangers the occupants of the vehicle but also poses a threat to nearby vehicles and property. Has the problem been reproduced or confirmed by a dealer or independent service center? the problem has not been reproduced or confirmed by the dealer. Subaru has declined to cover the issue under warranty, attributing it to user-caused damage, which I strongly dispute. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? the vehicle has been inspected by Subaru, who declined to cover the issue under warranty. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? there were no warning lamps, messages, or other symptoms prior to the melting of the side mirror. The problem was first noticed recently, within two months of owning the vehicle. Additional comments: I have owned the car for less than two months and have taken meticulous care of it. The car is always parked in my garage, ensuring no sun exposure. The only place I have had the car washed is at the Subaru dealership, which further confirms that I have not done anything to damage the car.
