What owners say about the power train

Verbatim from NHTSA complaints, newest first
“My CVT Transmission started having problems with the Valve Body inside the transmission. On acceleration from a complete stop my vehicle would start "bucking" hard causing a violent back and forth rocking or "jerking" of the drive train and vehicle. I did not request a inspection of the failed Valve Body when I paid to have it replaced. The life and safety of myself and others are at severe risk of injury or death resulting from a complete failure of the Valve Body component when driving on highways or other roads because without any warning the vehicle will come to a complete stop which would cause a rear end collision possibly at highway speeds. Also I'm concerned about the Torque Converter having a failure because of the intense pressure from the failed Valve Body with the constant "bucking" on acceleration. I took my vehicle to both a independent transmission shop and a Subaru Service Center and the Independent Transmission Shop told me I needed a new transmission and the Subaru Service Department kept telling me they didn't know what was causing my vehicle symptoms. Subaru of America extended the warranty on my vehicle to 100,000 miles because of the…”

“The contact owns a 2011 Subaru Outback. The contact stated while driving at various speeds, the vehicle failed to properly accelerate while depressing the accelerator pedal. The vehicle was taken to the local mechanic who diagnosed that the transmission output shift was bent and needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were not notified of the failure. The failure mileage was 100,000.”

“Torque converter issue that causes stalling similar to a manual transmission vehicle. The issue should have been a full recall but instead was only a "bulletin." For my own safety, I am stuck paying several thousand dollars for an issue the manufacturer is aware of but refused to cover by full recall. It is not just wear-and-tear, and is a danger to myself and other drivers on the road. And because the previous owner(s) were negligent in making sure the vehicle was repaired under warranty, I'm left paying a giant, unexpected bill. Does that seem like the right thing to you?”

“When coming to a stop the RPM's drop and the engine will stall, similar to not engaging the clutch on a manual transmission. Luckily there has not been a crash to date but the condition has worsened to the point it is no longer safe to drive and must be repaired. This is a known safety flaw with the torque converter and Subaru denied any responsibility or assistance in the quoted $2,400 repair.”

“Coolant leak, steering power fluid leak, break pad leak, gasoline line leak, seat heater, clicking noise after turning off car, leaking seats and rear view mirror also leaking, steering wheel expanding due to possible air bag, heater and ac vents lose and also chemical smell/gas/coolant coming from front and back of car, sunroof not secured. Every wiring wet, charger port in middle compartment wet when plugging something in. Everything auto does not work. Car sounds like something is constantly leaking air or gas somewhere, even when off. My safety was at risk by having severe chemical burns on my skin everywhere, hair falling out due to exposure, almost passing out while driving due to inhaling components, low visibility due to auto dimming in rear view and side mirrors. The problem has not been confirmed due to me being in a financial bind at the moment. The car has not been inspected. due to financial problems I am not able to get the vehicle looked at. There were no warnings except for the blue temp light came on but immediately will shut back off. Car also severely vibrates when turning on. They started appearing around against of 2024”

“Bought vehicle from Carvana, immediately noticed transmission shudder issues when driving near 50 mph. Brought vehicle in to multiple repair facilities. It had warped brakes, bad calipers, needed a new torque converter at least and the repair shop recommended a total transmission replacement. The whole vehicle shakes when driving near that speed or braking.”
