I hand washed my 2015 Subaru Forester using a garden hose with no pressure nozzle on the hose. While drying it I noticed a very strong burning smell. I then noticed smoke coming from the drivers side door mirror. It smoked for 30 to 40 seconds. Afterward my key fob door locking/unlocking functions do not work. Also the dome lights and clock do not work, as well as the TPMS. When I lock the car with a key, it only locks the drivers door. If I lock the car manually with the inside push button and close the door all doors are locked, but when I unlock it with the key the "Panic Horn" starts beeping. The car has not been repaired yet and is available for inspection. There were no warning lights or messages prior to the smoking mirror. This happened inside a washbay and I was definitely concerned about a major fire, luckily this did not happen. …
Horn on steering wheel stopped working. Don't know when it stopped working, no lights, warnings on dash, nothing. You only use horn when you need it and when needed for safety concerns, it did not work. Almost got in an accident when needing horn which did not work and was first discovery of this safety defect. Same situation twice after first discovery of no horn while waiting for Dealership appointment day. But horn would work by pressing panic button on fob. Steering wheel, nothing. Dealer confirmed Steering Roll Connector causing horn to be inoperative on steering wheel. Very expensive basic safety component repair for Subaru customers. Best extended factory warranty back in 2015 was 7yr/100k mi. Our Subaru was only 8yrs 8mo old and with only 79k miles. Out of warranty, but Subaru of America did help with bill as a good faith jester being so close to being in warranty. …
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. …
While driving 45mph on an icy road (approximately 25 degree(F) outside temp) the car suddenly lost power as if the CVT transmission was in neutral. However, it was still in drive. Pressing the accelerator only raised the RPMs but no power was sent to the wheels. There were cars behind me and my car was slowing down due to no power. I was fortunately able to pull off to the side of the road, stop, put in park. I put back into drive, power returned, and car drove normally for the remaining ~10miles of my trip. No warning lights from vehicle occurred during this event. This sudden loss of power could have been very dangerous especially given the road conditions. If drivers behind me were not following at a safe distance the sudden reduction in speed could have caused an accident due to the icy roads. I have not yet taken the car to be inspected, but will do so as soon as possible.
Unknown origin. Airbag issues started in September October 2022. 2015 Subaru Forester. Vehicle with Heated Seats similar to open recall. Warning notice display as to Airbag dysfunction. Airbag determined to not function by Dealer. But informed not within the specific airbag recall affecting other same era (2015) Foresters now under recall altho symptomatically the same issues as other Vehicles subject to recall. Quoted up to $2000 to fix the Vehicle. Subsequently, the driver side warning assistance sensors have stopped working on the Vehicle. Because the VIN # does not fit within the recall matching system, Subaru could not replace the airbag without payment. Even after offering some payment accommodation on the part, Subaru wanted $1000 or so to repair and could not give a final estimate in advance. This Vehicle has less than 40,000 miles on it.
We had driven up Mt Washington in NH (about 6000ft high) and were returning back. We had used the X mode (hill assist) intermittently on the way down. Had driven almost 150 miles back to home, when the car suddenly lost power and started to shudder. We were able to coast to the side. We tried to start again and again the same problem. We noticed that the brakes seemed quite warm. After about 5 minutes we tried again and were able to drive slowly to a gas station, but no one to help since it was late. Since fuel was low at 1 bar (60 miles distance to empty). We filled up the tank and made our way home driving slowly on the back roads. We are not sure if it could be a problem with the fuel, electrical system, brakes or the hill assist. While the car seems to run fine on short trips of a few miles, have not taken it out on any longer drives.
