I have a 2015 WRX w/ the CVT and have been having some issues with it. All started when I had the first oil change done at Autowest Subaru in Roseville CA. After the oil change my car felt a Lil sluggish and was shifting hard for an automatic (I know in sport and sport sharp mode it shifts a lil quicker but this felt different than it was prior to the oil change. Then it started doing this thing where when I'd take off and hold it at a steady throttle not letting off it would shift really hard from 1st to what felt like 3rd then back to 2nd immediately back to 3rd then back to 2nd so on and so on until I let off the throttle. So I called the dealership and the service advisor said it's normal. I said bull**** and brought it in. After showing several techs what the issue was they finally took it in the back and 2 hours later discovered that the transmission fluid was over filled. This was at 3k miles now I have about 9k on it and it's still doing this funky shifting thing and I've taken the car back to the dealership several times one time they reset the transmission learning computer and that seemed to work for a couple days then it starts acting up again. Their telling me there's nothing they can do unless it starts doing it every time. I feel like I spent $30,000 on a lemon and the dealership doesn't give a ****. Any suggestions on what I should do would be appreciated.
