Subaru Forester electrical problems

24th February 2020 - Bought the car from Subaru dealer. Couple of service records prior to May 24, 2022. - May 24, 2022 (9,037 miles) | RO# 806326: The lower oil pan leaked prematurely and had to be completely replaced under warranty. During the same visit, explained LONG BRAKE PEDAL issue, and was given an estimate. - - June 1, 2022 (9,039 miles) | RO# 806767: Just 2 miles after that repair, the oil pan had to be torn apart again because the internal oil level sensor failed and got stuck. - January 19, 2024 (18,854 miles) | RO# 838995: The vehicle suffered a dangerous engine shutdown in the middle of traffic due to the factory Thermo Control Valve defect (TSB 09-80-21). While resolving this safety defect under warranty, the dealer used scare tactics to upsell me $794.23 out of pocket for unrelated maintenance. - July 3rd, 2025 - You can see from invoice records that indicate, customer requesting a quote on repairing the windshield chips, as I learned on 26th August 2026 (during call with Subaru corporate) that it was under extended warranty, dealership offered me a quote and did not volunteer to repair at no cost nor conveyed information on extended warranty. This damage happened twice due to poor quality of Windshield in my car. - 23rd August, 2026 - 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. - 24th August, 2026 - Similar incident happened the next day. - 25th August 2026 (39,000 miles) | Present Day: The lower oil pan seal has failed yet again. Dealership is suggesting a battery replacement. Shared inspection video shows, rusts on bolts, very unusual for a car driven only 39000.

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.

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

The contact owns a 2021 Subaru Forester. The contact stated that while trying to roll up vehicle windows from driver sits and passenger sit they would roll up to 3/4th all the way up and they would roll back down after. The contact stated this was a recurring event. The dealer was aware of failure and diagnosed issue needing repairs for window regulator and run channels for driver and passengers side. Manufacturer was made aware of failure and let contact know it was outside of warranty. The failure mileage was approximately 22,500.

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.
