2021 Subaru Forester

I am filing this complaint regarding a recurring and dangerous safety issue with my 2021 Subaru Forester. The auto stop/start feature intermittently fails to restart the engine after it shuts off when stopped. When this occurs, multiple dashboard warning lights come on, an alarm sounds, and the vehicle requires putting the transmission into "Park" and shutting it down completely before it will start again. This has happened multiple times at intersections, traffic lights, and freeways during rush hour (stopping and starting frequently), leaving me temporarily stranded in live traffic. The local Subaru dealership service department was unable to replicate the issue, however upon inspecting the vehicle's charging system, the battery was found unable to hold charge from the alternator and was replaced on June 9th, 2025. Now after less than 1 year of replacing the battery, the problem persists. I have been made aware of TSB 16-118-24R (TCM reprogramming for auto start/stop restart failure) and TSB 09-80-21 (Thermostatic Control Valve failure) which appear directly related to this issue. This is a serious safety hazard. A vehicle that cannot restart in live traffic puts the driver and other motorists at significant risk of a crash. I am requesting that NHTSA investigate this issue and consider a formal recall.

While driving this car on April 4, 2026 at around 6PM, I experienced the distinct smell of gasoline. I had driven for about 5 minutes on our way to a local restaurant that is approximately an 8 minute drive from our residence. My wife said that she had just filled the gas tank that afternoon. After arriving at the restaurant, I checked the gas cap to ensure it was tightly sealed. I also checked to ensure no fuel was leaking from the car. After finishing dinner, we I drove the car back to my residence and once again, 5 minutes into the drive, I smelled gasoline. After we arrived home, I check the vehicle exterior for leaks and found no liquids under the car. The following day, April 5, 2026 at approximately 1115 AM, having once again found no liquids or gasoline under my car, I drove the car to my local repair shop; an 8 minute drive. About 5 minutes into the drive, I smelled gasoline again. I parked the car at the repair shop, but while adjusting the parking to fit better between the painted lines, I saw and heard a large puff of smoke from the hood area. I immediately put the car into Park, shut off the engine and ran from the car. After exiting, I saw that the car ignited with visible fire under the engine compartment. I called 911 to request fire department help. No damage to any structures or other cars occurred. Q1 Above: No the car is totaled and unavailable for inspection as far as I know. Q2 Above: I had to run from a burning car. Q3 Above: No. Q4 Above: Yes, the car was inspected by my insurance company, USAA. Q5 Above: No, there were no warning lights or any indictor that there was trouble. I would like to note that the car was brought in to my Subaru dealership service station (Hyman Brothers in Midlothian, VA) for a heater element safety recall several months ago.

Automatic start/stop fails to turn car on - intermittent. Taken it to Subaru detailer miltiple times and paid for services to correct the issue, but the issue persists. Fist time - replaced the battery in July 2025. 2nd time, went on a ride along for 1 hour, issue did not happen, replaced spark plugs, issue persists. 3rd time, updated TCM software, issue still persists. Subaru of America is aware of the issue and have not gotten a resolution either.

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!

After arriving home from a short drive to the grocery store I parked my car in the drive way and went inside. On the drive home I could hear a low humming coming from the speakers and the car was decelerating when the accelerator was not being pressed, no warning lights or sounds came on. About 10 minutes after I parked a neighbor knocked on the door letting me know my car was smoking from inside the hood. Within a minute or 2 the entire hood of the car was engulfed in flames. The entire front half of the car burned to a crisp, the fire also burned half a tree. The car was burning so hot that it melted the hood of the car, had I parked it with the hood facing my house my house would have caught fire. The problem has not been reduced or confirmed by dealer or independent service. The vehicle is being stored by the insurance and for the time being is accessible for investigation. Because I was having trouble with the infotainment system, the humming coming from the speakers, and a recent warranty extension by from Subaru for the infotainment system due to known issues I suspect that the fire was caused by electrical issues.

We purchased a 2021 Subaru Forester Touring SUV on [XXX] at the El Cajon Subaru dealer and this July, I experienced the transmission (CVT) inadvertently shift from drive to neutral twice in one day. This was a concern to me and after I did research online, I was very surprised to discover that this has been an apparent issue with the CVT transmission. We then arranged to have the vehicle towed to the Kearney Mesa Subaru in San Diego for them to diagnose the problem. They found NO issues! I contacted the Subaru Manufacturer at Subaru.com and received a Case # and Jorge, a customer service individual called us today, 8-6-2025 , to address my inquiry. He informed us that if the dealership was unable to duplicate the problem then he was unable to request further action. This was an issue that he was unfamiliar with, or had ever even heard of, and could only suggest that we have the vehicle seen, again, by another dealership to see if they can determine the problem. This is very disappointing as we have only driven this vehicle less than 1000 miles since purchasing. And since I'm now reluctant to drive any distance in this vehicle, or on freeways, will need to have it, again , towed to another dealership as suggested! I would very much appreciate any information you can provide on how to approach this circumstance and if you have encountered any additional complaints specifically related to the Subaru CVT transmission shifting unexpectedly into neutral. Thank you for your attention to this request as we find this a significant safety concern that needs to be addressed. .INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I commute with my car and recently it started to speed up all by itself. I removed my floor covers thinking the gas pedal might be stuck on it but that wasnt the problem. While accelerating from a stopped position, it revs up and accelerates rapidly all by itself. Tapping the break pedal to deactivate accidendal cruise control doesnt work. I have to slam the break just to stop it from accelerating on its own. This is the fourth time it's happened. I have my personal mechanic change the oil every 3k miles and follows the factory recommendations on all other manufacturers recommendations. Very scary to drive because it happens at random.
