2022 Subaru Outback: engine stalls while driving

Filed Oct 6, 2026 · Electrical, Engine · OR

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.

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 dealer then stated the battery was weak and replaced the battery. The new battery tested good after replacement. One week later, the issue returned again. A consistent pattern is that the problem occurs when it is hot outside and the vehicle has been running for more than one hour. The vehicle has been inspected by a Subaru dealership multiple times. The problem has not been reliably reproduced by the dealer, but the dealer previously confirmed a failing high-pressure fuel pump and later a weak battery. Warning lamps appeared at the time of failure, including multiple dashboard lights/check engine-type warnings after the engine shut off. There were no consistent warning messages before the stall/no-start events.

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 taken the vehicle to a Subaru dealer for diagnosis.

I experienced two serious electrical failures within a few days that caused the vehicle to stall without warning. At Nov 29, 2025, after parking for about 20 minutes, the car would not start. Symptoms included: • Very weak clicking from the starter • Dashboard flickering and dimming • Unable to shift out of Park without manual override • Jump-start did not work even though power was delivered The vehicle was towed to the Subaru dealer. The dealer reported: • Battery “low but fine after charging” • Alternator “normal” • Starter “normal” • No warning codes On Dec 2, 2025 the vehicle had been released without repairs. Only a few minutes after leaving the dealer, the car stalled in live traffic during an Auto Stop/Start event. Symptoms: • Immediate loss of all electrical power • All warning lights flashing erratically • Hazard lights did NOT illuminate externally • Gear shifter locked again • Vehicle would not restart on battery • Subaru roadside assistance jump-started the vehicle With Auto Stop/Start disabled, it was barely drivable and returned to the dealer. This appears to be a serious electrical or charging-system failure, possibly involving: • intermittent alternator failure • voltage collapse during Auto Stop/Start • BCM or power distribution fault The vehicle can stall unpredictably in traffic without warning, creating a significant risk of collision.This is not normal battery discharge — the battery was fully charged at the dealer minutes before the second failure. I am filing this complaint because this issue is dangerous and the dealer cannot reproduce or diagnose it. A formal investigation or recall may be necessary.

Automatic auto off-on began to fail and car didn't start well. I began to disable the automatic auto on off while driving because it began to sound like it would stall out while stopped at a traffic light . Then I forgot to disable the automatic auto off on and car stalled out while stopped at a traffic light. I took it to dealer, Rafferty Subaru, they couldn't find anything wrong with it. Then a few days later check engine light and other icons started flashing on dashboard. I took it to dealer, they said the gas cap was off. For the next week the automatic auto off on sounded like it would fail so I disabled it, the car didn't start normally every morning, and it began to feel like it didn't shift correctly as I accelerated or slowed down. About one day later it suddenly lurched to almost a stop while driving, check engine light was flashing, other icons on dashboard were flashing, the Park Brake icon started flashing. The engine continued to run but I couldn't go more than 2 mph. I put it in park and it started to smell like something was burning so I turned it off. I had to have it towed to the dealer, Rafferty Subaru.

The relatively new car (2022) stalls out randomly at intersections and red lights. This is a major safety issue as we have had the car totally shut down in the middle of 2 busy intersections. We had to dial 911 and have the police come to assist. We brought the car to the dealer and they did not find a problem but it continued to happen. There were no warning lights or messages - stalling happened randomly. May be related to the gas saver engine stop feature when at a complete stop.

Multiple occasions of dead battery or stalling in an intersection have occurred since the car was 6 months old, with mileage of only 3,000 miles. Dead battery accompanied by electrical malfunctions such as loss of nav system, climate control system, and driving safety systems. Battery failure in cold weather in Michigan winter resulting in long waits for tow truck. Loss of heat in very cold temps on a road trip.
