“Bought car in 2013, have replaced the turbo 3 times! First within less than a month of ownership. Again in 2016 & again 3 months later. January 2018, again the car left me stranded for the 4th time! The Outback has been in the garage for almost 4 weeks, only to find out the turbo had a stripped support, which cost me a 'new, used motor!!! I bought my 1st Outback in 2000 off the showroom floor, never had any major repairs, just routine maintenance. Drove her until sept 2013 due to a crash, which was totaled.”

NHTSA complaint #11173599, filed 2019-02, 124,000 miles

“This is the first Subaru I've ever owned and so far it's been a nightmare. I have had to repair: an oil leak in the engine that required the whole engine to be taken apart. While replacing a seemingly simple part, the hydraulic lifts that keep the back hatch open, the threading that holds the screw in broke off and I had to hire a mechanic yet again to weld that part to be able to screw in the screw to hold the lift in place. And now, the entire interior lighting doesn't work, including the stereo, all the dome lights and the remote control system. …”

“Subaru Outback 2.5xt. 2005 check engine light came on & I could hear whistling or whoosing sounds from engine area. Took it to an auto repair place slowly,asap & there it sits. Has 155,000 miles on it & I maintain & love my car! The gears in the turbo 'broke apart' & left shards of metal in oil pan & at this time who knows where else. Was hoping there was a recall as I maintain my vehicles & it seems like a manufacturer error.”

“Driving on interstate freeway, in heavy traffic, with the cruise control set, when the vehicle suddenly lost all power and throttle response. The check engine light came on, and the cruise light started blinking. Engine continued to run at high idle but speed and RPM were not maintained. I was lucky enough to cross 4 lanes of traffic and stop. Turned off the engine, which was running at 2200 RPM. After a brief stop and investigation, I was able to restart the engine and drive normally to an auto parts store. I scanned the obd ii code (DTC code) and found p2138 - throttle position sensor. …”

“Head gasket leak causing anti-freeze leaking.,. Began after 100k extended warranty expired. Told that caused due to defect in engine design. Later models with new design have not had problem. Subaru is knows about issue, but not taking any action to compensate for repair (ext. Cost around $3k).”
