“Please read upload documents. My 2015 Subaru Outback began showing signs of excessive oil consumption in the summer 2018. Apparently this was a known problem with Subaru and class action lawsuit was filed against Subaru for models made prior to 2015. My vehicle failed a oil consumption test in the fall of 2018. I was told by white bear Subaru if the vehicle failed an oil consumption test Subaru of america would pay to have a new short block installed due to this ongoing engine defect. …”

NHTSA complaint #11174234, filed 2019-02, 65,000 miles

“I was going 55 MPH on a straight flat surface when all of a sudden the RPM's shot up to around 4000 but the car was not accelerating. It was like it went into neutral. I pulled over to the side of the road and the car proceeded to die. Fortunately, it started right up and I drove home. I had a almost a full tank of gas. I had only driven it for 5 minutes as I was on my way home from work. I just had the oil/filter changed not even 2 months ago. I have 54,000 dealer serviced miles on the car. It was 86 degrees out. 2015 Subaru Outback premium 2.5”

“I warmed the car up and drove to shoprite. Twenty minutes later I returned to the car to put the stuff away to go home. When I pressed the button to start the car only the radio started and the message flashed keyless start up deactivated see manual. I saw the manual could, just about understand it, did what it told me nothing changed. I called roadside assistance at Subaru and the lady said it was my battery even though I told her what the message said on the screen. She sent someone to jump the battery .when he arrived 50 minutes later the car started perfectly. …”

“Gas pedal sensor dose not respond on take off from stopped vehicle. Have almost been t-bone 5-6 times. Also from a cost to putting pressure on pedal it fails to respond. On left turns you are a sitting duck not knowing if pedal will respond or you are sitting out in front of some closing in on you at high rate speed . This has happened 10 -12 times on highways an city streets”

NHTSA complaint #11014803, filed 2017-08, 52,000 miles

“Unintended acceleration. When driving at low speeds--what would traditionally be 1st and 2nd gear (the car has a continually variable transmission)--and while keeping constant pressure on the gas pedal, the transmission changes the acceleration of the vehicle on its own in a process that feels like it can't find the right gear , and it provides a jerking feeling (usually only a couple of jerks ). …”
