2015 WRXcvt engine surges
For awhile now I've been having these annoying power surges, usually when getting onto and up to high way speeds. The car is completely stock and use premium gas. Happens wether full throttle or not and you can usually feel when it's about to start happening because the rpms go higher than usual for the amount of throttle being used. I tried to have the Subaru shop take a look and see what's wrong but they couldn't replicate it and found nothing wrong, in an attempt to fix it they pulled the plugs and reset the computer. From talking with people in my area that own Subaru cvts this isn't an issue any of them have been having. The videos were taking from two separate incidents tonight and no change on my part with the throttle. If anyone has any ideas as to what is going on I'd love to know. Thank you!

So are you not pushing in the throttle after the first rev and the rest of rev spikes are the car independently doing it? That would scare the **** out of me.
Or is it just more power then youre used to? |

That's all the car. After I feel the initial spike I get off the throttle to bring the rpms back down, sometimes after doing so the problem won't occur but other times getting back on the throttle brings it right back to doing that. Definitely not afraid of power but have never had or been a car where this is an issue. Trying to get the videos uploaded now

Hell no thats not normal! Throttle should only respond if you touch it. Turbo or not lol
What happens if you brake when it surges? Does it stop it? |

As soon as I'm off the throttle it stops. And to be clear, that is happening with the accelerator pressed but not moving it. When that was happening tonight I was around 60% throttle according to the display

The TC is part of the tranny...Hopefully it's just the converter and not the bands of the transmission itself...don't know much about the cvt...hopefully you're under 36,000 miles?

Yeah I'm going to do that but will honestly probably get another we couldn't replicate it or couldn't find the issue.

Definitely not normal. Show them the videos and explain to them what's happening.

There is a tech tip that talks about surging issues if the oil is over filled. If I remember right I had a similar issue with a forester xt. I ended up having to do a tranny relearn and issue went away.

Did you ever figure out what was causing the issue? I’m having a similar issue with my 2015 WRX with a CVT. But mine has a stage 1 tune and intake so I’m afraid the dealership will make a big deal out of that.

It's a 2015. You have warranty to 100,000mi / 8 or 10 yrs on that transmission.
What you're describing is a shot CVT transmission. Get it replaced under warranty and if the car is perfect until the rest of your lease consider keeping it; if it's anything less than perfect dump it on Subaru at the end of your lease. |

Sounds like a slipping CVT belt.

it's normal, traction control is holding the tranny back.
Try it with the traction control off (push once). Fyi, simple way to test if your belt is slipping or not, is put in Drive with brake, and rev the engine. The rpm should not pass 3k, if it passes 3k then your tranny is going out. Last edited by Shinka; 09-12-2018 at 09:00 PM. |
