Subaru Outback stalling problems

Filed Oct 26, 2026 · Electrical, Engine · FL

I purchased this 2024 Subaru Outback three months ago with 19,000 miles. It currently has 26,000 miles and is still under its factory powertrain warranty. On October 25, 2026, after completing a short trip, I was stopped at a red light on State Road 524 in Cocoa, Florida. When the light turned green, the vehicle began to accelerate forward, but the Auto Start-Stop system failed to successfully restart the engine, causing the vehicle to completely stall in the middle of active traffic. I shifted the vehicle into Park, depressed the brake, and pushed the ignition button to restart it. Instead of cranking, the vehicle experienced total electrical chaos—the dashboard, infotainment screen, and interior electronics began flashing erratically, and the engine refused to start. The vehicle had to be pushed out of the path of traffic by hand and subsequently towed to a Subaru dealership. The dealership confirmed that the Auto Start-Stop system had critically drained the battery below operating thresholds. There were absolutely no prior warning signs, dashboard battery lights, or slow engine cranks leading up to this event. The vehicle simply died without warning in live traffic. This creates a severe safety hazard; had this stall occurred while merging onto a highway like I-95 during stop-and-go traffic, it easily could have resulted in a high-speed rear-end collision. Because Subaru does not provide a permanent override switch for the Auto Start-Stop feature, drivers are forced into a recurring safety defect with no warning indicators that the system is about to fail and strand the vehicle.

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.

2010-2018 TR580 Outback Torque Converter Lock-up failure symptoms in TSB 16-90-13R fits my 2011 Subaru Outback. 2.5I Premium, (TSB) Originally issued on 1/6/2014 + later revised on 5/7/2014, Early yrs of the TR580 suffer from TCLUF, which causes stalls + bogs down during stops or idling at traffic lights, premature wear, valve-body/solenoid failure, overheating, breakdown of transmission fluid/coolant + Catastrophic Chain Failure. These issues were exacerbated by Subaru specifying these transmissions have a "lifetime fluid" that never has 2 be replaced. Most Subaru failures were related 2 fluid breakdowns. The Subaru lineartronic CVT, designed in house by Subarun2 integrate w the company's longitudinal boxer engines + AWD system, built by Subaru in Ōizumi, Town in Ora District, Gunma Prefecture, Japan. lineartronic launched about 7 yrs after Nissan's 2003 X-Tronic CVT arrived here. Nissan had lots of trouble w early CVT's which led 2 transmission failures. As is the case w most new tech in a specific market sector, especially CVT's, the most Subaru CVT problems occurred in the 1st few model yrs. Each time my family or myself drive we are putting our lives in dire jeopardy, risk + danger of wrecking + even lost of life, too many close calls by peeps that almost rear ended us at a light, because of bogging down or almost stalling. The engine shudders + RPM drops very low as the vehicle stops, feeling as though a man trans car is stopping w/o a clutch being pressed. The problem was never fixed or looked into by 2 different dealerships + even though Subaru issued TSB 16-90-13R, identified wear of internal torque converter thrust washer as that wear can prevent lock up clutch from releasing properly, effectively keeping engine mechanically connected 2 transmission as vehicle stops. Subaru's corrective part used a needle bearing design instead of the earlier solid bushing.

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.
