2024 Subaru Outback WildernessEngine & coolingFuel system

After refueling, that is a period of time where there is hesitation and sputtering with the engine. It is a problem due to not being able to fully accelerate into traffic. No warning lamps or messages noted. This has not been seen by a dealership for this. This has becoming more of an issue happening most every time I fill up.

The auto start/stop function on my vehicle malfunctioned while I was in heavy traffic. The auto start/stop function shut off while stopped in beltway traffic but did not start again when it was time to begin moving again. The dashboard lights flashed and I attempted to turn the car off and restart it, but the vehicle would not start. This was a serious safety issue because I was stranded in a busy highway lane with cars passing at high speed on both sides, unable to safely exit the car or move the car out of the...

4-5 lanes of traffic. Fortunately, a police vehicle was stopped behind me and he was able to put on his emergency lights and secure a safe exit from the vehicle and clear the lanes closest to the side of the highway. He assisted me to push the car to the side of the beltway. I called AAA and the technician charged the battery. The car did start but I had it towed to the Subaru dealership in case the same issue happened again. The dealership took a week to replicate the problem and eventually came to the conclusion that it was the battery. They did not mention that this issue has been documented in some Subaru models. A Google search advised me that this has been a recurring issue and advised that I submit this report to NHTSA. The dealership replaced the battery and the issue has not happened since, however I have mostly been turning the auto start/stop feature off manually for fear that the same thing might happen again. Unfortunately I did not learn about this issue until after the dealership had returned the car to me. I believe they only replaced the battery and no further manufacturer inspections were mentioned. The battery part is PB001993.

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.

2026 Subaru Outback WildernessEngine & cooling

At approximately 500 miles from delivery, the vehicle experienced a catastrophic mechanical failure caused by a malfunctioning PCV (positive crankcase ventilation) valve, which resulted in oil fumes being expelled through the exhaust system. This is a manufacturing/component defect that should not occur in a new vehicle at such low mileage, and I have serious and reasonable concerns that oil contamination may have affected the catalytic converter, oxygen sensors, and/or other emissions and engine components,...

regardless of whether the PCV valve itself has since been replaced. I want to be clear about the severity of this incident, as it is directly relevant to the safety concerns underlying my request. The failure occurred while I was driving on a New Jersey highway, approximately 1.5 hours from home, alone in the vehicle with my two young children, ages 6 and 8. The vehicle began emitting a volume of smoke from the tailpipe significant enough that three separate police vehicles surrounded my car out of concern that it might catch fire or explode. This was an extremely frightening experience for both myself and my children, and it is not one I am willing to risk repeating in this vehicle, regardless of what repairs have since been made. I also want to note that I received no warning lights or indicators on the dashboard before or during the onset of this failure. The smoke was first visible outside the vehicle and only afterward began seeping into the cabin. The absence of any prior warning is of particular concern to me, as it means I had no opportunity to pull over or take precautionary action before the situation became visibly hazardous. Subaru is refusing to provide a new lease to me.

NHTSA Complaint Narrative - Draft On July 9, 2026, in the evening, my leased 2026 Subaru Outback Touring caught fire while we were driving home. We were stopped in a left-turn lane waiting on a left-turn signal. When the light turned, the vehicle in front of us moved forward - which, in hindsight, was fortunate, because molten metal was sprayed across that exact spot moments later. The engine effectively exploded, throwing molten metal from the melted hood and engine components into the air around the car. We...

exited the vehicle immediately, leaving it burning in the left-turn lane. The fire department, based only about half a mile away, arrived within approximately 4 minutes, but it still took them roughly 35 minutes to fully extinguish the fire given its intensity. The vehicle had just been returned that day (or very recently) from a 3.5-week internal engine repair at the dealership. This was the third time I had reported the same underlying engine problem to Subaru - the recent lengthy repair was the first real attempt by the dealer to address it, and it failed within days of the vehicle being returned to me. My spouse and I were in the car moments before the explosion. Had we been delayed even briefly - for example, had the car ahead of us not moved forward when it did - we believe we could have been seriously injured or killed by the explosion and flying molten debris. The vehicle was a total loss. I am filing this complaint because: This was the third report of the same engine issue prior to the fire, indicating a recurring, unresolved defect rather than an isolated incident. The failure occurred immediately after a dealership repair specifically intended to fix this problem, suggesting the underlying defect was not - or could not be - properly corrected. The nature of the failure (explosive engine fire while driving, throwing molten metal across an active traffic lane) presents a serious risk of injury or death to occupants, other drivers, and bystanders

Vehicle was not accelerating properly, so took to the dealership (Mike Shaw Subaru) to have work completed. Technicians indicated that the engine valves (shim valves) all had to be replaced and other work needed to be performed such as: Intake manifold, shim valves, gasket throt chamber. After dealership assured me that all work was performed and car was okay to take home, the next time it was driven it burst into flames. After filling the tank with gas the vehicle was at a red light. Once accelerator was pushed the vehicle engine burst into flames. Unsure if it is a faulty part or incompetent technician

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.

My 2024 Subaru Outback has twice become inoperable while stopped at a traffic signal. In both incidents, the engine was off while stopped, but the vehicle remained powered on and would not restart. The vehicle also would not properly power down. The car could not be safely driven or moved and required towing both times. This created a serious safety hazard because the vehicle became disabled in active traffic and could not be restarted or properly shut down. After the first incident (on [[redacted]]), the Subaru...

The dealership has now had the vehicle for approximately three weeks and states they cannot replicate the issue. No cause has been identified and no repair has been made. During one of these incidents, my [[redacted]] child was in the vehicle while we were stranded in traffic. This appears to be a repeat electrical / ignition / operability failure affecting the vehicle's ability to restart or properly shut down after stopping in traffic.

The engine, running at idle in and out of gear, did not respond to input from the gas pedal. Pushing the gas pedal did not have any effect on the engine revs. This was dangerous because I was attempting to enter a busy roadway and suddenly was faced with zero throttle response although the engine was still running and was in gear. The car has 5,300 miles. The transmission failed at 1,300 miles and was replaced by the dealer. The present incident began when, for unknown reasons, the car battery did not have...

enough power to start the car after being parked for 30 minutes. I got a jump start, and after letting car run for several minutes, attempted to leave the parking lot as described above. The car would move in forward and reverse at idle speed, but there was absolutely no response to gas pedal input. The car was towed to the dealer who will look into this.
