2022 Subaru Outback electrical system problems

“My Subaru often stalls when the start-stop function is happening such as when I stop at a traffic light. When I lift my foot off the break, the engine tries to restart, but stalls out. It happens at almost every stop. I had my battery tested and it is fine. This week, the car actually completely stalled out in heavy traffic and I had to put it in park and restart it.”

“In September 2026, after a jump start, my vehicle's battery emitted a strong sulfur/rotten-egg odor, indicating overheating and overcharging. I was advised to shut it off immediately. The vehicle is now undrivable and parked, and I am concerned it presents a fire risk. This is the latest failure of a chronic electrical defect documented in the dealer's own repair orders since early ownership: •⁠ ⁠March 16, 2023 (4,985 mi): vehicle needed a jump start. Dealer tested the battery, said it passed, and blamed my driving habits. •⁠ ⁠May 16, 2023 (5,503 mi): vehicle again needed a boost. Battery failed the dealer's test and was replaced under warranty; dealer cited Subaru bulletin 07-213-22R. •⁠ ⁠August 4-8, 2025 (15,188 mi): vehicle again needed a boost. Battery failed the dealer's DCA8000 test (low CCA) and was replaced a second time. A dark-current draw test found the Telematics Data Communication Module (DCM) causing a parasitic draw (code B2A0C); the DCM was replaced. When I arrived to collect the vehicle after being told it was repaired, it would not start in the dealer's own shop. Subaru paid for the DCM repair as one-time goodwill while stating it was not…”

“My 2022 Subaru Outback Premium has had repeated intermittent stall/no-start events. The exact failed component is UNKNOWN, but the issue appears related to the fuel system, engine control, electrical system, or heat-related sensor/relay failure. The vehicle is available for inspection upon request. The first event occurred while parked: the engine shut off/would not start, while the dashboard and screen remained powered. After about 30 minutes, it started again. A later event occurred while driving: the engine suddenly shut off, but the dashboard and infotainment screen stayed on. I could not restart the engine for about 10 minutes. When it restarted, the vehicle would not accelerate past about 30 mph, suggesting reduced-power/limp mode. This created a serious safety risk because the vehicle lost motive power while in traffic. The vehicle was taken to a Subaru dealership. The dealer diagnosed the high-pressure fuel pump as failing and replaced it under the powertrain warranty. About one month later, the same issue occurred again while parked: the vehicle shut off, all dashboard warning lights illuminated, and it took several minutes before it would restart. The…”

“The contact owns a 2022 Subaru Outback. The contact stated that while driving at an undisclosed speed and making a left turn, the message "EyeSight Disabling" was displayed. No warning light was illuminated. The vehicle then lost motive power and was unable to restart. The contact called 911, and two bystanders assisted in pushing the vehicle to a Jiffy Lube. The vehicle was towed to the dealer, who determined that the battery had failed and needed to be replaced. The vehicle was not repaired. Upon research, the contact associated the failure with the engine. The manufacturer was made aware of the failure. The failure mileage was approximately 58,000.”

“I parked my 22 Subaru Outback in my enclosed garage about 11:00 AM. I was in and out of the garage at least five times between 11:00 AM and 6:00 PM and in a room next to the garage the rest of the time. At 6:00 PM I went into my backyard. Upon returning inside the house about 7:30 PM I heard the car running in the garage. The car had remotely started sometime between 6:00-7:30.The keys had been hanging up all day and were not touched. My phone had been placed on a shelf and was also untouched between 6:00-7:30. There was no explanation for why the car started in the garage. Fortunately it wasn't while we were asleep. We took the car to the dealer the next day and were told it was impossible for the car to start under the conditions described above and there was nothing wrong with the car. Although we never had issues with the car previously We drove it from that dealer to another dealer down the road and traded the Subaru for another car so we no longer own it. I just wanted to report it in the event this is not an isolated incident.”

“On May 19th 2026 around noon time, while we (me and my wife passenger) were driving my 2022 Subaru Outback Touring (2.5L, non-turbo) in active congested traffic on our way to airport, the engine shut off as expected by the Auto Start-Stop system when I came to a stop. When I released the brake pedal to proceed, the engine failed to automatically restart. The vehicle became immobilized in a live traffic lane, creating a serious safety hazard with traffic backed up behind me and oncoming vehicles unable to predict my situation. No warning lights or alerts preceded the failure. After shifting to Park and pressing the ignition button multiple times, the engine eventually restarted. There was no prior history of stalling, no check engine light, and the battery and vehicle have been maintained per Subaru's schedule. This is a critical safety defect: a vehicle that disables its own engine in traffic and fails to restart on demand puts the driver, passengers, and surrounding traffic at immediate risk of rear-end collision. The Auto Start-Stop system should never leave a vehicle stranded in a live roadway. The vehicle is available for inspection. I have/have not yet…”
