Subaru Forester electrical problems

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 but in order to replace the DCM to the 4G it will cost upwards of $2000.

Car drains battery. 45,000 miles and has had 3 batteries and have been told it needs another. Dealer says start stop switch, requires a battery of 750 CCA and not the Subaru recommend battery. Car will die in traffic and driver seat adjusts to different positions by itself. Told that these problems will never stop unless I get a higher rated battery than required.

While at a Stop as the engine turns off and awaits decompression of brake to turn on again vehicle moves forward bit, then the engine shuts down while in drive (stalls) had a vehicle hit me in rear but luckily I had my trailer hitch on because it saved me from body damage . I had to place in park and restart this has happened several times before and I’m kinda nervous and makes my wife nervous when stopping at lights or stop signs it might turn off in the middle of the intersection. When this occurrence happens all dash lights pop up … I checked engine with code reader after the incidents but it doesn’t give out any info on what could possibly be happening. I had the Dealership change the Thermo control module in 2025 but these occurrences has happened before and after the TCM replacement.Having the dealership check is like wasting my time and money because they aren’t able to pinpoint the cause without a code . There has to be a problem somewhere in the system it’s just that the dealership in Hawaii has no clue ..

There was a recall on this vehicle from 2022, and we did not own this vehicle at that time. Recall passenger side airbag contact under seat can cause fire or electrical issues. I contacted Subaru and they said the recall was satisfied in 2022. If that's the case, the repair piece must have been faulty as the issue has come back. The dealership I took the car to said they have seen about 4 of this same issue within the last two weeks. Subaru is unwilling to assist in this, and I cannot pay the 1800.00 dollars the dealership wants to repair this vehicle. I've asked more questions of Subaru since their answer and have not received a response. I would like to know why their website says this was complete July 15, 2025, not 2022. It was not complete in 2025, or we would have had the repair done. Any help in getting someone to see if this is in fact another recall and how to tell if the recall was truly completed in 2022, possible faulty recall parts now. This is crazy if numerous folks have gone in with the same issue. We need Subaru to take a good look at this.

REPORT OF FAILED RECALL REMEDY (RECALL 19V-149 / WUE-90) My 2015 Subaru Forester experienced a total recurrence of the defect addressed in 2019. The vehicle became trapped in 'Park' intermittently on several occasions before remaining immobilized. During one incident, the manual shift-lock override failed to function. While the brake lights functioned during these incidents, the failure to shift is a documented symptom of a failing brake light switch. I had the switch replaced by a technician who initially suggested a full shifter assembly replacement. However, replacing ONLY the brake light switch immediately and permanently resolved the issue. This confirms the recall-related part was the point of failure. Subaru of America was notified but declined to acknowledge this as a failure of the safety remedy. I am also reporting intermittent 'ghost' activations of the right turn signal stalk.

My 2022 Subaru Forester Sport, <24,640 miles, suffers from persistent, life-threatening safety failures. Thick white exhaust is present in every temperature, and a heavy burning smell fills the cabin during acceleration regardless of outside temperature. I have been dealing with these failures since March/April of 2023. My car was in a rear-end collision in May 2023 and was repaired at an authorized Subaru body shop. Despite these authorized repairs, the mechanical and electronic failures have continued to deteriorate. My car has required 4 emergency tows and was out of service for around 90 days in 2025 alone. It has been to several independent mechanics and they tell me that since everything happens intermittently, I must take it back to Subaru as it should be covered under warranty due to the low mileage. However, four different authorized dealerships consistently claim "nothing is wrong". My car sits at these dealerships for weeks at a time without a significant change in the odometer. I had 2 claims with Subaru of America this year, including a claim for the vehicle randomly unlocking itself (not via remote), but they closed both claims and nothing was done. Ongoing failures in steering, suspension and braking systems make the vehicle unstable and dangerous to drive. I have a 2-inch thick file documenting repeated service visits for these specific issues yet Subaru refuses to acknowledge or repair them. The primary computer system, media system, and Eyesight (ADAS) safety suite fail daily. The dashboard lights up constantly when these safety features fail. The system frequently freezes and resets while driving, which disables all safety and navigation features without warning. The remote start fails to warm the car after 10 minutes in cold weather; once the heat functions, the car is filled with chemical fumes. All of these issues continue to get worse as time goes on.

Two incidents happened first battery died, we replaced the battery. Then Battery died again, we replaced the alternator on June 5, 2025. Then on Saturday September 13, 2025; all system lights came on at once on the dashboard then the battery died again. Car locks up and is stalled out. Cannot restart car, has to be towed. We replaced the battery cable and cleaned the terminals. Three months later, December 1, 2025; the battery light came on then all system lights came on at once, the battery died again. This happened on Interstate 95, it could easily have caused a crash. Car locks up again and is stalled out again. Cannot restart car again, has to be towed again. Something in the electrical is causing this, we do not know what.

Subaru Forester 2019 January - February of 2025: issue initially presented as the hatch beeping, indicating that it was not closing fully. The hatch would not pop back up as if something was in the way, just remain down & continue beeping. The car would then not start, with only the hatch beeping noise (beep beep beep) going off. When I drove it, it kept warning me that the hatch wasn't shut completely. After I parked it in the garage, the next morning it would be dead. The issue was supposedly resolved in February of 2025 as I replaced the battery on my own and replaced this part: 29182AA060. Schomp Subuaru reported no issues with their diagnostic tests. November 30th - December 2025: I started the car just fine. When I opened the trunk and closed it, it gave me three beeps and wouldn't fully close, even if I pushed it shut and locked it. The next morning, the car would not start - the battery was dead. The tow company also could not jump start the car. As the car was being towed, the hatch alert was the only thing working/beeping. Even when not trying to use the hatch. I have used the car every single day up until this issue started. I have not left the keys in the car. The car is now back at the dealership. The unreliability of this can/has left me and my passengers stranded and cold. The dealership found no issue the last time this occurred even though there was a class action lawsuit about this exact issue, but somehow my car was not considered included. I cannot have Subaru tell me that there is no issue again.
