Vehicle is burning oil, oil came out through where the dip-stick is placed. Found oil on the exhaust tips. Mass air flow sensor is malfunctioning. Requires new coils and spark plugs even though I have already replaced them. Required a new battery, however, replacing the battery did not keep the vehicle from turning off by itself. O2 sensor, bank 1 sensor 2, is also malfunctioning.

Driving on the highway at ~70 mph and suddenly lost all throttle response, the car would not accelerate only loose speed. Engine started to shutter to low rpms, and because of this drastically lost speed and nearly got into an accident with oncoming traffic while moving to the side of the highway to pull over. After eventually pulling over, engine continued to shutter to low rpms and could not hold an idle - would just stall after repeated attempts to start it up. Car was towed to closest dealership and after waiting 4 days finally heard it was the engine wire harness that needed to be replaced. Researching the issue I found that Subaru made a design change for the wire harness to prevent water/moisture failure which is most like what happened to my vehicle. Stuck with a $1400 bill due to a design flaw, I decided to purchase a 2020 model which hopefully doesn't have the same issue. After calling Subaru of North America and explaining the situation, they offered me $1000 towards the new purchase. It was a kind gesture however I question if it is somewhat admission of guilt for the design flaw. 2015 WRX 138K miles was meticulously maintained with all necessary maintenance completed at proper intervals and oil changes every 3-4K miles.

2015 WRX 2.0L manual transmission while driving the car in everyday situations I have had (3) distinct problems associated with the engine/throttle/idle. 1) ghost blip: When coming to a stop, around 5-15 mph, put it in neutral coast to a stop idle will inexplicably spike from ~700rpm (idle) --> ~1.2-1.5K RPM (for a second or two...like a ghost blipped the throttle). No pressure applied to accelerator. 2) rough idle: While sitting at a stop, in neutral, ~700rpm (idle) --> will dip to ~650-600rpm for a fraction of second & reoccur every 2-4 seconds. Feels like someone lightly shaking your seat from left to right. 3) near stall: While sitting at a stop, in neutral, ~700rpm (idle) --> will dip the rpms low enough that the whole car noticeably shakes...similar to the shake you would experience if the engine were actually about to stall. The rpms will fumble around a bit and then hiccup back to normal idle after 4-5 seconds. All three items have been brought to the attention of the local Subaru dealer on (2) occasions w/ the reply unable to diagnose problem and/or it is normal.

I do not drive my vehicle very often as I drive my work truck six days a week. I got into my vehicle before getting on the freeway and realized I needed gas before I left. I got to the gas station with my gas light on and parked. After paying for gas I realized my gas cap access door was not open, as I thought I opened it. I tried multiple times opening the door with the release lever on the floor by the drivers seat. After twenty minutes of confusion I called the dealership and they told me to bring it over right away ( good thing they are down the street from me). After waiting for about an hour and talking to the tech and service writer I was able to obtain information on the cause of this (some what). There is a part on the release mechanism that is weak and fails causing you to not be able to access your gas cap. This could be catastrophic if you are on a road trip or away from any dealership. The service writer also had said this is fairly common with the new 2015 WRX and they are getting about two vehicles coming back with the same problem per week. Subaru needs to take responsibility for their faulty design and recall all vehicles affected. This should be investigated immediately.
