Good Day! I bought my 2021 Subaru Outback XT Onyx in Jan 2021. I had waiting 6 yrs for Subaru to use the Turbo Motor in the Outback again. I've had this car for 5 years with my warranty running out Jan 2026, but I only drive 5000-7000 miles per/yr. Current odometer is 29,901 miles. At my most recent oil change service at the Dealer, they showed me a video of my cars drivetrain from underneath. There were two bad seal leaks. One at the transmission pump housing and the other at the Upper Oil Pan. I had been there for an oil change a year earlier for the same service and there was no mention of these issues! After speaking with the service advisor, he said to call Subaru Customer Advocates. They listened to my situation and a few days later offered a $1400 credit for a $4000 job that involves the removal of my cars engine (upper oil pan) to replace it because it's bolted to the frame there. The other leak seal involves dropping the transmission. These are major repairs that following will dampen my ownership experience after decades of Subaru praise by Americans. I researched this issue online and found out there was a manufacturing defective regarding the silicone liquid seals they used for 2020-2022 Outback, Ascent, & WRX! This procedure was used throughout the driveline with the Turbo Motor & CTV Trans. There are 1000s of accounts of this defect placing burden on the owners of these cars who bought them in good faith. I did the research, called the dealer & Subaru with the discovery & overall complaint! I asked for 80% to 100% help with these repairs because how many more will I have to deal with after these two are repaired??? I have received zero responses from either after expressing that this was a known defect, Bullitens went to all the dealers, nothing was mentioned to the owners, and they've just covered those cars still under warranty. Since I didn't drive enough, the seal issues on my car took longer to start leaking, and then out of warranty. HELP!
NHTSA complaint #11758285 — an unverified report by a vehicle owner.
The contact owns a 2020 Subaru Outback. The contact stated that on various occasions upon bringing the vehicle to a stop or upon acceleration the vehicle had experienced a total loss of automotive power, and all of the warning lights would remain illuminated. The vehicle was taken to a local dealer where it diagnosed and the contact was advised that the battery, and thermal valve were faulty and needed to be replaced. The battery had been replaced five times however the contact noted that the failure persisted. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 19,000.

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.

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

The contact owns a 2025 Subaru Outback. The contact stated that the vehicle failed to start while attempting to start it. There were no warning lights illuminated. A tow truck company successfully jump-started the vehicle, and the vehicle was towed to the local dealer. The dealer was unable to duplicate the failure. The contact returned to retrieve the vehicle, and the key fob failed to operate, and the vehicle failed to start. The dealer provided a loaner vehicle. There was no indication that the battery had failed; however, the dealer replaced the battery. The dealer had not yet determined the cause of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was approximately 10,000.
NHTSA complaint #11753796 — an unverified report by a vehicle owner.
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

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.

The warning lights on our 2020 Subaru Outback have lit intermittently for the past 2 years. When bringing the vehicle into the dealer for service and oil changes, this was reported. Recently the TPMS light began to light intermittently. Tire pressure was checked and adjusted but the problem persisted. When we brought the vehicle in for service, it turned out that all tire pressure sensors needed to be replaced BUT the service techs identified other problems that surfaced JUST AS THE CAR WAS NOT COVERED BY WARRANTY - the most serious being an oil leak caused by FAILURE OF CAM CARRIER SEALS. This caused a dangerous condition where oil was leaking onto the engine and into the spark plugs. I find it odd that this EXPENSIVE issue was not discovered sooner. Subaru and only Subaru has been servicing this vehicle since new and they should have caught it.

There is a crack in the exhaust manifold and the exhaust smell is entering the cabin affecting driver and passengers' health. The problem has been confirmed by a Subaru dealer and an independent mechanic. There were no warning lights, I was made aware after routine maintenance by an independent mechanic. The same part has failed in multiple Subaru models: Recall WUJ-95 (SOA says my car is not covered in the recall/campaign due to my car's production date being 24 days after the "Affected Production Dates") . Additionally, Subaru of America extended the exhaust pipe warranty on the same part on other models, as late as 2018, so the part continued to be in use and problematic. Subaru of America says replacing the part is not covered by a recall for my car, however I feel strongly that it SOA should replace the part due to the proximity of my production date and the continued issues with the part across multiple models.

NHTSA issued a notice for a recall on the 2015 Subaru Outback for an exhaust pipe bellows crack which causes exhaust noise and odor which affects emission and engine performance. I had noticed our Subaru's exhaust smoke coming in through the air vents while idling and also a general loss of power for the vehicle. When I dug into the causes, I came across this recall and did the VIN look up on the NHTSA website and also the Subaru website for active recalls. The Subaru website states that the recall was completed. I then called the subaru retailer to check if there were any records for the recall work that was completed for NHTSA ID Number: 10199936. They could not find any records. I called in Subaru corporate to see if they could shed any light on the recall. Subaru corporate says that the recall work was performed on August 6th, 2020 but is unable to tell me where it was performed or even if it was actually replaced. My local Subaru dealer has no records and Subaru corporate says that the work was performed. I am stuck with an exhaust leak that is potentially dangerous as time goes on where it might fail emissions. Subaru corporate has not wanted to address this or investigate the discrepancy, but instead asks me to work with the dealer to get records. The dealer says there's no records of the work ever being done. So I'm in limbo with a particularly faulty car.
NHTSA complaint #11746783 — an unverified report by a vehicle owner.
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.

On Monday [XXX] were driving on [XXX] going north up [XXX]. I was doing about 60-65 mph in traffic which was flowing in both directions. While ascending the pass, the car suddenly started to misfire, rapidly lost power, power steering failed and all dash lights lit up. With no shoulder to pull out this was a very scary experience. Eventually managed to limp to a spot where I could pull out off the pavement. Car was dead. Popping the hood showed significant battery corrosion. I had a toolkit with me. The voltmeter measured the battery voltage at 9.3V. Thinking maybe cleaning the battery terminals would allow the car to be restarted, I managed to get the cables off and cleaned everything with a wire brush. But still no power. After a while a state trooper passed by and hung on while I contacted a towing service. After another 1.5 hours, the tow truck arrived and towed the car the 60 miles or so to the dealership in Denver with my wife and I in the cab of the tow truck. Dealer repair invoice indicated Data Control Module (DCM) "causing excessive draw on electrical system." More significantly, the battery had drained below the the operating threshold voltage required for vehicle drivability (understood to be 10-10.5V). There was no mention of this by the dealer service adviser. Although dealer diagnostic was carried out, no computer codes were provided. Vehicle mileage at time of incident 73,456. I have owned the car since new and have all service records. Car was repaired and picked up from dealership on 06/10/26 with a replacement DCM. Battery was charged up but not replaced and left in corroded state. Battery will probably have been weakened by such a total discharge with reduced life expectancy. I have uploaded the dealer repair invoice. I have reported this incident to Subaru of America. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
NHTSA complaint #11739030 — an unverified report by a vehicle owner.
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.
