2022 Subaru Outback: engine failure

Filed Jun 26, 2026 · Electrical, Engine · MD

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.

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.
