2021 Subaru Forester

The contact owned a 2021 Subaru Forester. The contact stated that while driving at approximately 4 MPH and slowing to park, the vehicle accelerated on its own. The contact stated that the vehicle drove out of the parking lot and crashed into a wall. The contact stated that the air bags deployed and that the vehicle had then shifted into reverse (R) and driven out away from the wall and crashed into a parked vehicle and stopped. The contact stated she was unaware of any warning lights. The contact stated that she had 1 passenger in the front seat and 2 passengers in the rear seat. The contact stated that everyone was shaken and achy, but no cuts or other injuries. The contact stated later that the passengers went on their own to seek medical attention. The contact stated that the passenger front bumper, hood, and wheel well were damaged, and the rear bumper on the passenger side had damage from the crash with the parked vehicle. The contact stated that the other vehicle had minor damage to the right rear quarter panel. The police were called and issued a report. The vehicle was towed to a collision repair shop, but had not been repaired. The vehicle had not been diagnosed for the independent acceleration and reverse failures. The contact stated that her insurance provider had not yet declared the vehicle a total loss. The manufacturer was not informed of the failure. The failure mileage was approximately 30,000.

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.

On January16,2026 while driving from Houston,TX to Austin TX the vehicle experienced a complete loss of power on Highway 71 W. We were traveling at approximately 70 MPH when the engine completely failed. We were forced to immediately pull over onto a narrow shoulder Our situation at that point was dire: we could not exit the vehicle as other cars were speeding by. Fortunately an emergency vehicle from the Texas Department of Transportation pulled up behind us with his emergency lights flashing. He told us we were in a dangerous situation and, due to our location, he was not able to tow us to safety. Our only option at that point was to allow the emergency vehicle to puss us to a safe location off of the highway. The driver pushed our vehicle approximately 1/2 mile to a motel parking lot. We contacted Austin Subaru, arranged for a tow truck, and proceeded to the dealer. The dealer technician advised us the Thermo Control Valve had failed. We were told this failure was common. The repair was at no charge since Subaru, being aware of the problem, had extended the warranty on this part. The action by Subaru to extend the warranty instead of proactively replacing the part before failure seems blatantly irresponsible

I am writing to file a formal complaint regarding repeated, severe, and dangerous malfunctions of the vehicle's engine Start/Stop (Idle Stop) feature. The system is failing to operate as intended, resulting in the engine stalling while the vehicle is in motion or under crucial driving circumstances, creating significant safety hazards. History of Incidents I have experienced four separate incidents where the engine unexpectedly stalled or shut down, creating extreme risk: Incident 1 (Railroad Tracks): The engine stopped while I was actively driving over railroad tracks. The car stalled on the tracks, and within seconds of the engine restarting, the crossing gates came down and a train passed. I narrowly avoided being hit by the train, missing the impact by approximately ten seconds. Incident 2 (Heavy Traffic/Bridge): During heavy, back-to-back traffic as a bridge (PGA bridge) was opening, the car momentarily stopped and then resumed movement. The unpredictable stopping motion created a severe risk of being rear-ended, as the following vehicle would have had difficulty anticipating the sudden, unintended stop. Incident 3 (December 2025): While taking a right turn, the engine stopped suddenly, with dash lights blinking, during only a slight pause in vehicle movement. This occurred while the vehicle was still maneuvering. Incident 4 (The following day): The engine stopping malfunction described in Incident 3 occurred again the next day. Attempted Repair and Ongoing Concern Two years ago, the dealership installed a new battery following the first two incidents. However, the problem has now recurred this week (December 2025). The dealership has informed me that using a third-party device to permanently disable the Start/Stop function would void the powertrain warranty. Causing Mechanical Stress: I believe the continuous, potentially faulty activation is putting unnecessary stress on the battery, electrical system, and engine components, which may ultimately shor

My Subaru has an auto start/stop. I was at a complete stop, making a left-hand turn, and my car completely shuts off with the following message: For safety, auto restart disabled; eyesight with a \ through the words, put car in park and restart vehicle. In the time it took me to put the car in park and restart, I was almost T-bone. This was terrifying. This had happened on previous occasion in stop and go traffic which is dangerous because my car has come to a complete stop without any warning to me where the driver behind me There are no warning symbols, warning lights, or any type of signal or symptoms to notify me that my car was going to stop completely.. Typically I remove my foot from the break, the car starts and then I put my foot on the gas pedal and the car moves forward. In the situations described above the car just stopped.It just flat out stopped. There’s never been any indication or signal to indicate the car is not going to restart The retailer replaced my battery and said it should help. I called the Subaru factory rep who was of no help. She said she is not a trained technician and all that she could offer to do was to contact the retailer. The dealer was not able to reproduce the problem. The retailer replaced the battery without any response about the safety issue. I asked if Subaru had a safety board I could report this too and the factory rep said no, but she will document it and they’ll do an internal review to see if we have any other similar issues reported, however, they will not contact me because they don’t talk to the public about these issues. I told her there are hundreds of these if not, thousands concerns online stating the same issue. The rep said she would document my concern. Documentation is good if there’s a fix but I’m concerned about the unnecessary death of a driver.The retailer also advised I could do the auto start override, I’m trying to make a point of how serious of a safety issue this problem can be. Thank you!

The vehicle has experienced four separate engine shutdowns while stopped in traffic. Each time, the engine turned off unexpectedly, requiring a manual restart. One incident occurred near a railroad crossing with my child in the car. The vehicle also lurches forward at low speeds and hesitates when accelerating after being stopped. These issues persist despite service visits. I believe they may relate to Technical Service Bulletins regarding the Auto Start/Stop and battery systems (TSBs #16-147-24, #10232217, #07-218-23R, #10251098). Subaru service staff have acknowledged awareness of these problems. I’m submitting this complaint to ensure the safety risk is documented and investigated.

Issue started with hearing a clunking noise from the front of the car, had the dealer inspect at 37,000 miles. They said they the clunking was caused by ECU issue and reprogrammed the ECU to correct it. Obviously, a software update did not correct the noise. Had an independent repair shop inspect the vehicle and found both front control arm bushings were cracked and torn allowing the control arm to move around causing the noise. Since the control arms are an integral component of steering the failure of these bushings could've caused loss of control, or an accident. They were replaced by the independent shop and now the noise is gone.

The contact continued to drive, and two blocks later, the vehicle stalled. No warning light was illuminated. The contact was able to restart the vehicle. The vehicle was taken to the dealer, where it was diagnosed with battery failure. The battery was replaced. The contact picked up the vehicle, and on the drive back to the residence, the vehicle stalled. The contact stated that the vehicle was almost rear-ended by the vehicle behind. The vehicle was towed to the dealer. The dealer replaced the fuel injectors. The contact picked up the vehicle, and the following day, while driving to work, the vehicle jerked abnormally and the vehicle stalled. The vehicle was towed to the dealer; however, no cause for the failure was found. The vehicle was not repaired. The contact stated that the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 32,000.

Unintentional Acceleration - 2 times within 4 days of each incident. 9/17/25 while stopped to pull into a parking lot my 2021 Subaru Forester accelerated as I was stopped. I had to slam on the brakes, take a deep breath and was shocked at the pull and speed the car wanted to go. 9/20/25 Pulled into a parking spot, not moving and the car again pulled and accelerated. Again I slammed on the brakes to stop from crashing into other vehicles or whatever was in the vicinity the car wanted to go. There were no warning messages, no symptoms prior to these 2 incidents. The car only has about 24,000 miles on it and all maintenance has been done on time and at the dealership. No outside mechanics have ever worked on the car. I called AAA to tow me as I was not safe to drive the car and had it towed to the Suburu Dealer where I purchased the car. This is an extremely dangerous situation. The floor mats were not near the gas pedal or the brake pedal and It was absolutely 100% not my error in foot pedal placement. I will not drive the car any longer until the dealer calls to tell me what is wrong or what they have found to be the problem. There is a civil lawsuit against Subaru for this situation but when mentioning it to the dealer they acted like they knew nothing about it. This is not something that should be ignored. I was lucky the 2 times it happened and I hope to God it never happens again!
