Default 2010 STI - Has the hesitation/ringland/tune problem been fixed?

Hi all, thinking of picking up a 2010 STI but wanted to do some research first. Has Subaru fixed the hesitation/tune problem in the 2010 STI's or are they still there? I know the 07, 08 (and possibly 09?) STI's had tune and ringland issues.

Would it be best to just get a protune right away (voiding engine related warranty) or just wait it out? I'll be doing a protune eventually anyway.

I would get the protune just to be safe. My 08 had a cobb ots map at 1k miles, had full exhaust and protune at 3k miles, and a stepped up to a big turbo at around 12k miles. Still stock block, still no issues at all and im about 37k miles right now.

Most of the issues seemed to be with the 08's. In 09 subaru changed many of the engine parts which seemed to help. The tune still sucks on the new ones though.

unless they changed the pistons you're still going to have problems.

if you're worried about voiding your warranty, how is the dealer ever going to know you got tuned?

I have a 2010 sti. Everything seems fine so far. The Cobb AP is not available for 2010 models yet, previous units do not work.

yep, i've heard that they're working on getting the ap-sub-003 working on the 2010s, but it will require more patience than i probably have, lol.

I too have a 2010 STi and I haven't found any issues with mine. As far as I know, there hasn't been any issues with 09's after, what I think, the August 2009 build dates.

IMO it's all in how you break the car in. I've been taking it easy, and doing random romps on her every now and then. I've been messing with the DCCD, the SI Drive, and modifying my driving habits so that I feel there is proper engine/drivetrain load. You take it too easy on her, and potential problems won't show until much much later. You run it like a raped ape, and your problems will surface before 2000 miles. Finding that middle ground is key. The crosshatching on new cylinders fade after something like 50-100 miles. So the piston rings set within that time. Just have to make sure they have the proper tension and the only way to do that is to flux the engine power.

Buy one if you're in love with it, duder. I absolutely LOVE my car.

With my 08 I spend half my time in love with it and half hoping it doesn’t blow up. It seems I can’t buy a car I like that doesn’t have some sort of potential ticking bomb issue.

I bought my 08 used from a friend with 8000 miles on it. He had the factory ECU reflash from SOA and then put an Invidia DP with a Cobb AP and a Stage 2 map. He went through the proper break in with it so hopefully it will be ok. But it scares me when I see another blown engine thread with 27,000 miles on it

Well,

This is comforting, considering I just placed my order for the Special Edition STi.

I'm with you on that... I've done the whole engine building thing (VW/Audi scene), I subscribe to the theory that was posted earlier on in this thread about break in periods. If you drive your new car off the lot with .1 miles on it and start beating the piss out of it immediately, then expect there to be a catostrophic failure within 3k-5k miles. After 500 miles, I'm down with beating **** up. This has been my experience with the vw 1.8t. But who knows, the Subie may be a different animal.

Knowing Subaru, they will change the STI next year... I'm surprised it lasted three model years...

I love these threads! In order for Subie to have corrected any 'issues' with the WRX/STI, they would first have to admit that there was an issue to be corrected. I haven't seen Subie ever say anything like that.

And to the post a few above this... about Subie changing the internals for 2010... Nope. There were a few stupid OP's that posted a while ago tha they saw something about Subaru released/published about the 2010's having hardened internals. . . That was true, but it was also true in 2008, 2007, 2006, ect ect. Naive people start these rumors.

So long as the pistons are hyper-cast and the OEM map runs lean because of emissions, you're going to get cracked pistons. If its an issue, then keep your car 100% stock to get your car fixed under warranty. If your car is coming out of warranty, then the world is your oyster and you can do whatever you want to your car. Personally, I've got a secret stash of $$ for a short block with forged pistons, just in case.

Oh you let the cat out of the bag now the wife is going to see this and find it and spend it before you find out and when your pistons do crack and you go to do a rebuild the money will be "missing" O.o


OP I would not lose to much sleep on this. If I was in your shoes ( which I am not shy a few grand ) then I would look to get a good tune after purchase and fall asleep with a grin on my face knowing what I get to wake up and drive the next morning.

+1. I have over 14k now on my late model 08 and the last 4k have been catless/ 20g. No issues yet for me but I also broke it in right and then tuned it at 900 miles.

Have to watch the oil consumption though. Mine had been sucking alot of oil out the PCV and into the turbo inlet when in boost. The stock air filter was very dirty after only 10k miles of AZ driving. Oil being sucked into the intake can/ will reduce the octane and can be a contributing factor to broken ringlands.
