2020 Subaru Outback engine problems

Filed Oct 30, 2026 · Engine · CO

Subaru dealer service tech reporting upper oil pan leak. The repair requires engine removal to gain access to the upper oil pan, which is a very costly repair. My concern, does the leaking oil get onto the hot exhaust system create a fire risk.

I have a 2020 Subaru Outback with just over 70,000 miles on it. Well before hitting 70,000 miles, there were two occasions where a loud, unusual noise occurred while reversing out of my garage. Additionally, I occasionally hear a strange noise when shifting into Reverse from Park. I also sometimes notice a whining or humming sound when accelerating from a complete stop, such as at a traffic light. Regarding the two loud noises I experienced, I have saved an audio file recorded by another consumer who posted it online describing the exact same issue — the sound is identical to what my car produced on those two occasions. The audio file is available upon request and may assist in diagnosing the issue. Please note that the date I provided for when the noise first occurred is approximate, as I cannot recall the exact date. Since the noise occurs most frequently during reverse, I am concerned there may be an issue with the CVT transmission.

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.

Vehicle: 2020 Subaru Outback Onyx/Limited/Touring XT (2.4L Turbo FA24) Component: Engine Lubrication / Oil Pan Sealant I am reporting a manufacturing defect involving the engine oil pan seal on the 2020 Subaru Outback 2.4L Turbo. Upon inspection of fluid accumulation at the transmission joint, a Subaru dealership diagnostic confirmed that the engine oil pan seal has failed. The dealership noted that engine oil is leaking and being forced rearward by airflow while the vehicle is in motion, saturating the transmission assembly. Technician Admission: The service department at the Subaru dealership explicitly stated that this is a "known manufacturing issue" with the FA24 engine series. Financial Concession: To acknowledge the nature of this premature failure, the dealership waived the $185 diagnostic fee, resulting in a $0 invoice (attached). Inadequate Coverage: Despite the dealership’s admission and a repair quote exceeding $1,100 (file is attached), Subaru has not yet issued a recall or extended warranty for this specific 2020+ turbo application, though similar issues with RTV sealant have plagued the brand’s newer engine platforms. The technician confirmed that the leak is significant enough that oil is traveling the length of the transmission. This presents a potential fire hazard if oil contacts high-temperature exhaust components (such as the turbocharger or catalytic converter) and contributes to environmental contamination. This is the Turbo (XT) model. Turbochargers generate much higher heat, which makes an oil leak significantly Subaru National Customer Service has advised me to file this complaint with the federal safety agency. I am requesting that the federal safety agency investigate the frequency of oil pan seal failures on the 2020+ 2.4L Turbo (FA24) engine to determine if a mandatory recall or extended warranty (similar to past CVT or engine seal settlements) is warranted to protect consumers from the high cost of a documented manufacturing flaw.

A fire started under the hood of my car while I was driving. There were no warning lights on in my car and the temperature gauge was in the middle where it usually is. Earlier in the day, I smelled gas, but I thought it was a different car as the smell of gas went away after a car that had a lot of exhaust coming out was no longer in sight.

Car stalled in traffic. The engine was cranking but it would not start. Had AAA tow off the road and to my home. Car sat for 10 days waiting for a fuel pump (thought this was the problem). After sitting for 10 days the battery was totally dead! New fuel pump installed battery was jumped but could not start the car. After 2 hours on the charger the battery still did not have enough energy to turn over the engine. Car is in a certified service shop (Wilhelm). Battery replaced and same starting issues with the new battery and the new battery is discharging at a very high rate even though the car is not starting. Bought the car used in 2023 so I have no knowledge of the history of the car. Service provider running factory diagnostic testing but so far no determination as to cause of the high rate of discharge. Verified that the fuel pump is fully operational. What we know is that with a fresh fully charged battery and a working fuel pump the car will not start and remain running. The engine stops and the battery drain is excessive.

Hi: When I was driving yesterday, the engine warning light and brake warning light both turned on. The car was like frozen on the road cannot be moved no matter how to press the gas pedal. The police helped to call tow and move my car out of the road. The tow driver left my car at a flat parking lot. On the lot, when I tried to restart my car, the car started to shake side to side and up and down. I can feel some part is dislocated and one piece of heavy thing was swaying in the car. The engine warning light was on for two times during the last two years. First time when I sent the car to the dealership, they performed the check and fixed it by free. The customer service person told me the problem is the sensor failing and the fixing was free. So, I guess it is the system defect and the manufacture already knew it. So the repairing was free. However, with one year, the situation happened again. The second time I sent the car for fixing, the service person told me it was the same problem of sensor failing but they charged me around two hundreds dollar for the second time fixing. Yesterday, the same situation happened again with the brake warning light on at the same time. It is almost another one year after the second time I sent car for repairing. My most concern is the car completely suddenly stopped during the driving. If I was on the highway, serious collision may happen and I am already passed away.
