Just picked up a new 2012 Wrx two weeks ago. I've tried to adhere to the break-in recommendation to the best of my ability, although I can't say it never went to 5ish. Anyway, the turbo used to kick in around 2,800-3,000 RPMs, now it doesn't seem to kick in until 4,000 or even later and it's definitely not the kick it was when I first pulled off the lot. It almost seems like the engine is flooded a bit. And when I push down the accelerator I almost feel little hesitations or shuttering. I know everyone say you get used to the power and therefore it seems slow, but the engine doesn't seem likes it's responding as it did for the first 300 miles. I want to take it in since it is under warranty, but I'm afraid the dealer might say they can't find anything wrong with it. Is this temperment common to turbo engines. I always thought that was the turbos of old. Any insight would be greatly appreciated. Thanks

I'll start by saying Welcome.

As for the power loss goes, I've never experienced this (except when my motor blew at 6k miles) and there was a significant loss in power on my way home from my friends house, this drive was when I realized the motor was blown due to no response, and the horrible noise coming from it.

Also, I've read on here about people getting hairline spits in the hoses exiting the turbo.
Honestly, it's got a warrantee, let the dealership check it out.

Any check engine lights? It almost sounds like you're having a misfire issue.

Trust your judgement, use the warranty, take it in.

At the very least, if they don't find anything, you'll have it on record that you had them look at it. You never know if/when that could be important.

Sounds like a boost leak to me and a CEL will not always be thrown when you have one. Check the piping coming from the throttle body to the top mount. Those little rubber slips around the pipe are crap just remove them and t-clamp that rubber hose and issue will go away. Hell I have even had it pop off after I went FMIC.

Are you sure you are not experiencing the "break in engine" mode. By pressing hard on WOT you definitely feel it the power surged around 3500 RPM for me. Now that I just passed 3K over the weekend, the engine is ab it tame now. But I still feel the power and maybe the engine throttle adjusted to my shifting habit a bit more.

But I'm no expert here....

I know this was posted last year, but I have had a similar experience with my 2013 WRX. The car always felt a little rough around the edges, which from what I read, was normal. However, I recently plugged in a OBD2 bluetooth reader and Torque pro android app, and my boost was never climbing past 4 PSI under heavy acceleration. I did a datalog, and my air fuel ratio was boucing around from 10-20 and all numbers in between. In talking with some friends who work with turbos and reading forums, it seems to be a boost leak. No CEL codes were thrown, but just an obvious decrease in power and smoothness. I will report back after my service appt. in 2 days.

Also, my friend brought up a good point that anyone having this problem must insist that their spark plugs be checked...If you are driving around (like I have) for a few months with this issue, your spark plugs might be close to shot, corroded, or what have you.
