2022 Subaru Outback

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.

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.

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.

After highway driving for 50 miles, stopped for a red light. Engine died but all lights stayed on. Sat 5 minutes with dead engine and when I tried again, the car started. Drove 1 mile to next light and it happened again. Went to Auto Zone (it was a Sunday and dealerships were closed) and they tested the battery which was 100%. Two days later, drove car for 10 minutes then parked for errand; 15 minutes later, car wouldn't start. Let it sit for a minute and it started right up. This happened 8 months ago (engine died at stop light after having been driven 30+ miles) but Subaru dealership could find nothing wrong. Also, radio speakers randomly will blast so loud it startles and distracts everyone in the car.

- Engine failure. Yes. - At a stop light the auto-restart function failed, following this event the vehicle began making a knocking noise, we towed it to the dealership for evaluation and their diagnosis was that it needed a new engine. - Dealership stated they too heard the knocking noise in the vehicle and it is engine damage due to low oil. However, the dipstick read fine when we took it into the dealership and we did not have a low oil warning. - Inspection completed by dealership - Received no warning lights nor messages regarding symptoms of the problem prior to failure. Initial event happened on 12/26 when at a stop light following the auto-off during braking function the car did not restart automatically. Car was turned off, and restarted. Following that event the vehicle had a knocking noise that increased in volume with driving. Did not drive the car after arriving to our destination. Towed the car to the dealership where we were told it needed a new engine.

Driving on the highway, engine started making a rattling noise, then began to labor and eventually stopped being able to accelerate at all. Oil pressure warning light came on around the time the acceleration gave out altogether. We pulled over to the side of the highway and got out of the car, seeing steam/white smoke coming out of the front of the car. The smoke increased and after several minutes, the front of the car caught on fire.

We had had no issues at all with our 2022 Subaru Outback until June 2025. Mileage at the time of the incident was approximately 52,000. We were driving one evening in June and all of a sudden the engine stopped and we could not drive it. It only produced a knocking sound when we attempted to turn the engine on. We had the car towed to the dealership and after taking the engine apart, they reported that an intake valve broke, flew and split one of the pistons causing the motor to seize up. There were no warning lamps, messages or other symptoms prior to the engine failure. Regular oil changes had been performed on the car. This issue came completely out of left field as we had previously had no engine issues.

While stopped at a yield sign waiting for traffic to clear so I may proceed with my left turn, I stepped on the accelerator pedal to make my left turn; however, my car did not go because the engine had turned off due to the auto stop feature. Once the engine restarted, I was no longer clear about proceeding with my left turn and had to apply the brakes very hard immediately to stop my vehicle. The auto engine stop is a dangerous feature that should not automatically be applied when starting the car.

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.
