The airbag warning light for the front passenger seat has been intermittently lighting. Both when the passenger seat is occupied and vacant. The light sometimes indicates the passenger airbag is off when there is a passenger in the seat. I took the car to the Subaru dealer where I purchased the vehicle.. Per the dealership service report: “SCANNED CODES AND FOUND CODE B1760 STORED IN BODY CONTROL MODULE REGARDING THE PASSENGER FRONT SEAT BOTTOM. RECOMMEND REPLACEMENT DUE TO A FAULTY OCCUPANT DETECTION SENSOR.” This car was recalled several years ago regarding the passenger seat airbag sensor issue. The car was serviced per the recall. This car has not been in an accident. The car has approximately 70,000 miles which were driven primarily by me. The front passenger seat was occupied less than 25 percent of the time. There was never anything spilled on the seat. The seat was not used to transport anything other than a passenger. The dealer service department now wants $1566.79 to fix this issue. I contend that recall did not fix the issue correctly and I should not be charged for a faulty part or design that was not properly remedied the first time. The dealer will not resolve the issue and has referred me to corporate Subaru. I have contacted Subaru and am awaiting a response. Case # 260818-1700931. This is a safety issue that Subaru needs to address immediately.
NHTSA complaint #11758062 — an unverified report by a vehicle owner.
This 2020 Subaru Forester has experienced repeated failures involving the Auto Start/Stop system. When stopped in traffic, the system shuts the engine off as designed, but on multiple occasions the engine has failed to restart normally when the driver needed to proceed. This has left the vehicle unable to move in active traffic and created a serious risk of collision. The failures have occurred in highly dangerous situations, including a busy [XXX], a major [XXX] intersection, and most recently while entering a freeway. In these incidents, surrounding drivers had to brake hard to avoid striking the disabled vehicle. The occupants reasonably feared a serious collision, and the events were potentially life-threatening. The battery was replaced, but the Auto Start/Stop no-restart condition later occurred again, so battery replacement did not resolve the problem. Subaru issued Technical Service Bulletin 16-147-24 on XXX for 2019-2021 Foresters. The bulletin addresses TCM reprogramming related to engine behavior during Auto Start/Stop restart and instructs technicians to reprogram the TCM when the described symptom is reported. However, the bulletin’s warranty section provides reimbursement under the Basic New Car Limited Warranty. For a 2020 vehicle, the original 3-year/36,000-mile basic warranty would ordinarily have expired before this 2024 bulletin was issued. The vehicle is now being evaluated by an authorized Subaru dealer. The condition is intermittent and dangerous because the driver cannot know whether the engine will restart when movement is required. The vehicle is available for inspection.

Airbag light came on - dealership confirmed it is an occupant detection system failure - wiring harness has gone bad. No history of moisture exposure, which would leave faulty part as the problem. Similar to Subaru recall from 2020 on heated passenger seats - this vehicle was not included in that recall, but is in the same year range and has heated seats. Entire bottom piece of front seat must be replaced, including wiring harness and seat mounting bracket; otherwise air bags may not deploy in case of accident. Quick online search reveals this problem has been prevalent in other 2018 Foresters not included in the original recall.

I brought my vehicle to an authorized Subaru dealership (Byers Imports, LLC in Columbus, Ohio) to diagnose the reason for the airbag warning lamp illuminating. The dealer had the manufacturer's WUM-98 Safety Recall (NHTSA Campaign Number 19V701000) performed to remedy a defective Occupant Detection System (ODS) sensor harness.Despite the recall remedy being completed, the Supplemental Restraint System (SRS) airbag warning light re-illuminated on the dashboard, completely disabling the front passenger-side airbag.The dealership confirmed that the passenger-side airbag remains completely disabled and inoperable due to a hardware failure of the internal occupant detection sensor mat. Because the initial WUM-98 recall was previously marked as "closed" in Subaru's automated system, the manufacturer refused to cover the repair under the recall. I was forced to pay $1,258.34 out of pocket up front to order a replacement front passenger seat cushion assembly (Part #64139SG061LL) to restore basic airbag safety to the vehicle.The initial federal safety recall remedy failed to permanently correct the underlying safety hazard. The vehicle continues to exhibit the exact same life-threatening defect (disabled passenger airbag) targeted by the original recall, and the manufacturer is shifting the financial burden of this failed remedy onto the consumer.

I have been having problems with my 2025 Subaru Forester since I purchased it. It has failed multiple times to alert me of people and cars when I am backing up. I have RCTW on my vehicle .Sometimes it alerts me when there is a car or person is coming behind me ,sometimes it doesn't. I have a video dated June 4th 2026. Three times people walked right behind my car when I was backing up. I almost hit them! I decided to video tape it. The back up camera also doesn't always work and did not go off when I was backing into the curb until I hit it without an alarm going off. The lighting alert system was also messed up because the light was on green until I almost hit the curb. This also happened on June 4th and I have a video. I could have hit a small animal or child or damaged my car. I have brought this to the attention of my Subaru Service department and they claim they can not replicate this problem.This is of great concern for me and I have filed a Lemon Law Case as I am too fearful I will hurt someone or myself because of these issues. In addition to this, my headlights are aimed down at the ground and I live on curvy country roads. Hard to see at night. My service department said Subaru of America would have to approve the adjustment. They never got back to me on this issue. The tech specialist told the service department manager that I had electrical problems with my vehicle as she witnessed the HVAC working improperly. My radio, navigations, phone and sound systems also cause distracted driving. The Radio would blast on high volume randomly . The navigation, phone and radio volume would be blasting without being able to turn this down. There is no way to turn off the radio. If you do, the whole navigations screen won't work. My navigation system is not functioning properly and has blacked out . Subaru has seen my vehicle 6 times for these issues . They claim they can't replicate the problem. My car is sitting in the garage. It is too unsafe to drive.

My 2021 Subaru Forester has a recurring, worsening defect in the Idle Stop/Start (ISS) system that creates a stalling hazard. When ISS shuts the engine off at a stop, the engine intermittently fails to restart when I try to move again. It cranks progressively slower, warning lights illuminate, a continuous alert sounds, and the vehicle cannot proceed until I shift to Park and restart manually. This has left me immobile in live traffic at lights, stop signs, and mid-turn. The system also attempts to shut down in unfavorable moments, such as mid-turn, or as I am already releasing the brake (meaning it was depressed only lightly or briefly); it then tries to restart while still mid-shutdown, producing a pronounced shake. This is not a battery-charge problem. It has occurred even when the battery tested above its rated cold-cranking amps, and after each failure the engine restarts smoothly by manual start, indicating the starter, engine, and fuel systems function normally. I raised this before 2024, but it was not recorded until May 2024. At that visit the dealer performed the TCM reprogramming in Service Bulletin 16-147-24 (Forester, auto start/stop engine speed drop on restart) plus an ECM update. A later visit added another ECM update. A dealer has now identified yet another TCM reprogramming, quoted for a fee. The failure has persisted across all of these updates. Dealer staff acknowledge repeated customer complaints with these exact symptoms and say there is no known effective fix. Because ISS cannot be permanently disabled through any factory control, I must remember to disable it manually every drive to avoid a restart failure in traffic. The vehicle is available for inspection. This is an ongoing, unresolved safety defect that repeated manufacturer software remedies have failed to correct, and it can leave the vehicle disabled in live traffic.

**Component or System:** Subaru EyeSight Driver Assist System (specifically the Pre-Collision Throttle Management system). **Incident Description & Warning Messages:** There were no warning lamps, messages, or symptoms of any problem prior to this failure. The incident occurred while I was stopped at a red light at a busy intersection. When the light turned green, I removed my foot from the brake and pressed the gas pedal to proceed, but the vehicle would not accelerate. The system had engaged a false-positive throttle cut. At that exact moment, the car began beeping repeatedly and the EyeSight logo flashed on the dashboard, incorrectly indicating an obstacle or imminent collision, even though the path in front of my vehicle was completely clear. **Safety Risk:** My safety and the safety of others were put at significant risk because the vehicle was unexpectedly immobilized in an active intersection during a green light. This sudden, unwarranted loss of acceleration created a high risk of being rear-ended by the drivers behind me who were expecting the flow of traffic to resume. **Reproduced, Confirmed, or Inspected:** Because this incident just occurred, the problem has not yet been reproduced or confirmed by a dealer or independent service center. Furthermore, the vehicle has not yet been inspected by the manufacturer, police, or insurance representatives.

Persistent Battery Drain on a 2021 Subaru Forester Limited. Problems began in year 4 of ownership (~17,000 mileage), after Subaru Starlink Subscription services expired. Red (Error) Starlink SOS indicator light was evident, where a normal light would show green. Battery would fully drain after about 3-4 days of inactivity while parked in a commercial garage. After repeated dead batteries, a jump-starter battery pack was used regularly, as well as a wall-outlet battery charger. The problem has not resolved with a new and appropriately specified AGM battery, replaced in December 2025. The only solution is to pull the engine-bay fuse #5, which disables the Data Communication Module (DCM), as well as other features (hands-free microphones and audio system). By pulling the fuse #5 consistently, the problem has ceased, even after a two-week period of no use. This provides irrefutable evidence that the DCM powered by fuse #5 is the source of the battery drain. The only resolution Subaru would offer was to insist on a dedicated diagnostic visit to a dealership, with the associated costs of hundreds of dollars to be borne by me, the customer, without a clear understanding of the costs or remedies to resolve this problem. I feel unsafe driving my vehicle for more than short trips given the risk of stranding or further electrical malfunctions that would impact critical vehicle functions or safety systems.

My new vehicle, with under 4,000 miles, has already suffered multiple chewed wires due to rodents attracted to the soy-based wire coatings used by the manufacturer. This is not a minor inconvenience — it is a serious safety issue. Damaged wiring can cause loss of power steering mid-drive, ABS and braking system malfunctions, airbag deployment failures, engine stalling on highways, and electrical fires — any of which can result in injury or death. The manufacturer knows soy-based coatings attract rodents, the consequences are safety-critical, and proven mitigations exist (capsaicin-infused coatings, hardened sheathing, metal conduit) yet are not implemented from the factory. If vehicles are engineered to withstand foreseeable environmental hazards like water intrusion, heat, and road debris, there is no justification for leaving critical wiring defenseless against a well-documented and predictable threat. A material choice known to invite damage, paired with insufficient physical barriers, is not an external cause — it is a design flaw.

Driving along and various system warnings came on, then started losing power, then the engine died and the car was completely dead. Got a jump start and the car ran for a couple of minutes and died again. Had it towed to a repair shop and when they checked it the next morning, they couldn't find a problem and it ran great for them. I replaced the battery and alternator just to be safe because we were about to leave on a trip.

2021 Subaru Forester The vehicle has experienced recurring electrical and battery-related issues for several years. The original battery was replaced by the Subaru dealer with a larger-capacity battery because of repeated starting concerns. The replacement provided only temporary improvement. The vehicle continues to experience rough starting on a regular basis, even after installation of a newer aftermarket battery with a higher cold-cranking-amp rating. The current battery is approximately five months old. The most significant safety concern occurs during Auto Start-Stop operation. On multiple occasions, the engine has shut off at a stop as intended, but then failed to restart when attempting to move again. When this occurs, multiple warning lights illuminate on the dashboard and the vehicle is unable to proceed until it is shifted into Park and restarted manually. Because of this issue, I now disable the Auto Start-Stop feature on every drive to avoid a potential failure to restart while in traffic. The issue has been ongoing for years and has occurred with multiple batteries, including the dealer-installed replacement battery and a newer aftermarket battery. The dealer suggested that an aftermarket dash camera could be contributing to battery drain. The dash camera was disconnected, but the problem continued. I am concerned that failure of the vehicle to restart after Auto Start-Stop operation could leave the vehicle disabled in traffic and create a safety hazard. The condition appears to involve the vehicle’s electrical system, battery management system, charging system, Auto Start-Stop system, or a combination of those components. The vehicle is available for inspection upon request.

Sirius add pop-up on the infotainment screen, locks you out of the system. Not allowing use of hands free calling, text or climate control. Recurring issue making vehicle unsafe.
NHTSA complaint #11741839 — an unverified report by a vehicle owner.
While driving the head unit was connected to Google automotive with Google maps giving me directions and music through you tube music when a full screen sized ad for Sirius XM took over the entire screen. I could no longer see the map and directions, couldn't use the climate control. The entire screen was locked by this add until I removed my focus from the road to hit the small X icon in the top right corner of the add to close it out. Ads for a product I've never used taking over my entire head unit distracting my driving and following the directions from Google maps is unacceptable and unsafe.

Problem: Recall for passenger side airbag malfunction in heated seats for my model year. Manufacturer has said they addressed the recall but they have not. My car and thousands of others are unsafe for passengers to ride in because the airbag system does not work. Warning light is the airbag symbol and message that alerts driver that SRS system is not working. Manufacturer and dealers want to charge $200 to look problem over and then tell you its off warranty. My car has 96000 miles and this has been a problem since they “did the recall”. Subaru tells owners that passenger should ride in back seat. How does that work with two car seats. Subaru needs to take responsibility for their engineering design and fix this safety defect. These cars are death traps.
