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 just bought my Subaru outback brand new in October 2025. I’ve maintained my oil changes at the dealership. I bought it from in the last one was last may 26. I filled up my tank with a full tank of gas June 1. On June 2 when I was driving home from work on the I 94 Highway in Detroit Michigan I was going about 50 mph when my check engine light went on and within seconds the engine failed. The car was still on, but the gas pedal wouldn’t work and I was in the far left-hand side lane of the highway. I was able to slowly pull over to the fire right hand shoulder, even though it was during peak traffic time. As I pulled over, I started seeing smoke come from under the hood. I then seen a big flame which made me quickly get out of the vehicle and then seconds two minutes later the entire vehicle was in golf in flames and had many explosions throughout. I had no prior indications notifying me that there was something wrong with my vehicle. I had no problems with it. There was only 12,500 miles on the vehicle. There was no obvious cause to this happening. It was only me in the car however if there were small children in car seats or less mobile elderly people in the car, I don’t think that they would have made it out safely. The fire department came and put out the fire. A police report was made with the Michigan State troopers. My insurance is progressing. They are working on a claim. I also contacted Subaru of America and opened up a case with them. I notified the Subaru of Troy dealership that this happened.

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.

Purchased my 2011 Subaru Outback 3.6R Limited from the dealership, new. Since 2013, the Subaru dealer has discovered multiple oil leaks, replaced the head gaskets 3 times, thermostat 4 times, the alternator 3 times, timing belt 4 times, radiator 3 times, starter once, and my HVAC system twice...all due to my engine seizing multiple times while driving on freeways. No warning lights, just the engine seizing suddenly. This caused a few minor bumper accidents on the freeways because of these incidents. Nothing was reported because no one was injured. Last year the engine was replaced with a used/refurbished one by the dealership. In less than 11 months after this engine was replaced, the dealership states I'm having multiple oil leaks again, most originating from the cam carrier. Now, my engine is struggling on slight grades. The newly installed used engine only came with a six month warranty and now Subaru states I need another engine replacement. Money is tight, so for now I'm keeping a pan under my car to catch the oil and I will keep topping off the oil every week.

The failure involves the engine (powertrain), which was under warranty. The vehicle has experienced four catastrophic engine failures resulting in sudden loss of power, including at highway speeds (65–75 mph). The most recent failure also involved an oil-saturated catalytic converter. These failures occurred between 06/25/2024 and 03/16/2026. During this ~629-day period, the vehicle was only in my possession for about 184 days, as it remained at the dealership for diagnosis, repairs, and repeated engine replacements. The issue remains unresolved. The vehicle is currently in my possession, available for inspection, and is not being driven due to safety concerns. All failures occurred during normal driving and caused sudden loss of power with no prior warning, leaving the vehicle inoperable and stranded. This created a significant safety risk due to inability to maintain speed or safely merge, increasing the likelihood of rear-end collisions. The failures have been confirmed by an authorized Subaru dealership, with multiple engine replacements performed under warranty and most recently as a goodwill repair. Both the dealership and Subaru of America have acknowledged they cannot determine the root cause. The dealership’s Operations Director stated the vehicle is not safe and he would not allow his family to drive it. The vehicle has been inspected multiple times by the dealership and Subaru of America. However, no inspection reports, diagnostic data, or detailed findings have been provided despite repeated requests. Additional issues (including a broken axle and oil-saturated catalytic converter) were only identified during a third inspection after being missed previously. Requests for explanation were not answered, and further details were withheld as “internal.” There were no warning indicators prior to the first three failures. During the fourth, a temperature warning appeared only seconds before failure.

This car is a very well-maintained, low-use vehicle with regular oil changes and routine maintenance performed on schedule. Early in this drive, I noticed an unusual hissing sound as I approached a stop. When I tried to brake, I realized my brakes didn't seem to be responding. I pressed the brake pedal harder and realized that with 50-100 pounds of pressure (guess), I could slow the car down. As I came to a stop, the engine died. I restarted the car, and it died again immediately. After the following restart, I realized I could manually keep the RPM up in neutral while at stops, and press with significant force to get the car to stop. Had I not been comfortable two foot driving or understood the issue, this surely would have resulted in a crash of some sort. The car indicated a check engine light, loss of traction control, a flashing BRAKE light, and a flashing cruise control light. I took the car immediately to a local shop where they identified the problem as a vacuum leak at the brake booster. The plastic piece that the hose clamps onto had cracked off, leading to this problem. This make and model does not seem to have a check valve downstream of this component.

The Tumble Generator Valve (TGV) assembly within the intake manifold failed on my 2019 Subaru Outback at only 48,000 miles causing catastrophic engine failure. This is a critical engine component that is expected to last significantly longer than the vehicle's current low mileage. The premature failure of this part triggers engine warning lights and disables key driver-assist safety features (such as EyeSight), creating a distraction and potential hazard while driving. This indicates a material defect in the TGV components used in this model year, causing catastrophic failure well before reasonable service life expectations.
