“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.”
“leak in cam carrier gasket caused large ammounts of smoke to fill engine bay and enter cabin air system. Struggled to breath and vision to an extent was obstructed. when car was parked, smoke continued to fill the engine bay. problem was confirmed by an independent technitian, with the vehicle undergoing a complete inspection about a year ago from the dealership of purchase. no warning lamps turned on until enough oil had seeped from the leak in the liquid silicon gasket, at which point the low oil warning light had turned on.”
“My 2016 Subaru Outback CVT transmission has exhibited an intermittent jerking and grabbing sensation when accelerating from a stop, worse when cold, since at least February 2023. This is a known defect covered under Subaru warranty extension bulletin 16-115-18. February 2023 — An authorized Subaru dealer documented the complaint in writing. The technician stated the vehicle never warmed up during the test drive and dismissed the concern. The CVT issue was never repaired. I was never informed of Subaru's CVT warranty extension program. February 17 2026 — seven days before my warranty expiration — the same authorized Subaru dealer physically identified and documented a CVT oil pump cover leak. The same jerking complaint was again documented in writing. No repairs were made and the warranty expired one week later. The CVT defect has been physically confirmed by an authorized Subaru dealer within the warranty period and Subaru of America has denied my warranty claim in writing. This issue presents a safety concern. The unpredictable jerking and hesitation when accelerating from a stop creates dangerous situations in traffic, particularly at intersections and when…”
“My 2016 Outback 2.5L model experienced an exhaust noise and/or odor coming from cracks at the bellows section of the front exhaust pipe which includes the catalytic converter. It was diagnosed as leak occurring at the front exhaust pipe. Quoted repair for replacement part only is $2700 plus $1000 labor to repair. Upon investigation, it was discovered that Subaru Recall WUJ-95 with subject Exhaust Pipe Front (EPF) Bellows Cracking was issued in 2020. My specific VIN was excluded from this recall but I have experienced the exact issue described in the recall. As a result of this situation and exhaust inhalation the car is not able to be driven, this cause breathing issues for me, my wife and our 9 month old baby.”
“Steering wheel controls frequently fail to work properly on the cruise control system specially the speed control. Also the exhaust system bellow has cracked. The moonroof leaks into the cabin and floor area of the passenger side. Also leaking into the A pillar on the passenger side. I only have a picture of the engine valve cover that is leaking and had to be replaced. I have video of the exhaust leak coming from the crack in the bellow pipe. Do not have video of the cruise control speed issues as I can’t take a video while driving.”
“The contact owns a 2016 Subaru Outback. The contact stated that while driving at an undisclosed speed, the low oil warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the engine seal had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 110,000.”
