Lol my car has never been to the dealership since I had it.

I was talking about my bud's 04 Wrx.

We always flashed a stock tune every time he went to get an oil change and scheduled maintenance.

It was just a precaution.

Your input is pretty much invalid.

They don't go scanning the ecu unless there is something wrong with the car.

And you advocating warranty fraud.

The 09+ have been known for having a bad tune. It makes the car run to lean. Best mod to get as soon as you get a wrx would be AP

Lol people on nasioc crack me up.

The crap stock tune has a huge impact on the bearings and engine's lifespan, as stated above.

And there's plenty of people who have switch their tune back to stock just for the dealer.

So yes I'm advocating it

P.S. it's 07+ that came with lean tunes

LOL. I don't believe for a second the "lean" tune is the cause for a spun bearing. Tell me how's that's remotely possible.

I also don't believe the OEM causes the ringland failures either as PLENTY UPON PLENTY of Stage I/II WRXs with perfect tunes have cracked the ringlands. There's some other flakey issue with the fueling system that has yet to show itself. If fixing the OEM tune with some sort of aftermarket tuning was the fix, then the data would suggest Stage I/II cars wouldn't be wrecking the ringlands. We know that's certainly not the case. Way more modded WRXs report ringland issues than OEM tune cars.

I never said it was the only cause, but it is one factor of most ringlands failures.

alot of people do not check their oil daily, so the bearings starve. And everything goes dry aka metal to metal.

Plus the oem pistons are just crappy.

My ringland theory: Subaru is running tight ring gaps to meet emissions (2009 STI FSM says 0.0091"-0.0110") and when the combustion cylinder temperature increases enough the gap completely closes, the ring is forced to expand, it sticks to the cylinder wall, and it damages the piston. I also theorize that it is made worse by people not letting cars and the oil fully warm up prior to hammering on it (internal engine clearances not correct). But that is just my theory; I'll test it if I ever hit the lottery. For now my stock 2009 STI with its crap factory tune has 31.5k "always warmed up before going to WOT and to Sport# mode" miles and the ringlands are fine.

Back to the OP's issue - bearings spin when the oil film between the bearing and the crank is gone or in the case of the early 2009 WRXs the bearing material is wrong for the application. Unless someone can provide a plot showing the combustion chamber pressure skyrocketing to some insane level, I do not see how a stock tune has anything to do with it.

Wonder if Subaru changed bearing material again for 2013?

I bet Subaru has not changed a single thing besides how their crank is treated and dual avcs/air pump setup.

If they did improve the oem setup there would be way less failures.

I'd be pissed off too if I spent 30-40k on a brand new Subaru wrx/sti

Then it spins a bearing, cracks a ringland or throws a rod...

This is the reason why changing to a gr would not satisfy me, because they have the same if not more motor failures.

I subscribe to the "always warmed up before going WOT" part of your statement. Not sure I follow why you wait to turn the dial to S#. To avoid temptation? My car's in S# as soon as the "you don't have your seat belt on, idiot!" beep stops.

For the seat belt nazis, I'm parked in a garage and have to get out to close the garage door, hence no seat belt when I back out.

That is 98% of it. The last 2% is that I do not fully understand the logic of the Subaru ECU so I cannot fully appreciate all of the changes that occur when I go from Sport to Sport#. I figure if I am not trying to enjoy the car for that few minute window then there is no reason to make the switch to extra power until things are warmed up.

I'd be curious to know the logic behind forcing the car back to Sport when it gets turned off.

That would set a bad precedent for the dealer to give you a new car. Everyone would use you as an example as to why they should have their entire car replaced, there's no way they would let that happen. No harm in trying, I guess (except it would mean a longer wait for the eventual repair). Good luck, I know I would be furious if my new STI failed on me.

As most people on this thread have said, the engine needs to be torn down so that SOA can determine the next step and what happened. I have authorized it and now I wait..As soon as I know what the next plan of action is, I will post it.

Update: I found out today that "the 3rd crankshaft bearing has spun" and they could do a short block replacement, but given the miles on the car and no abuse has been observed, they will do a brand new long block engine replacement( in their speak,replace the engine and swap the electronics). Post repair,we will talk about "compensation" for this inconvenience(SOA language). I may have the car back by this weekend or Monday after they do a through test..if my car speak is incorrect please disregard as I am new to this..thats all for now.

Warranty fraud is when they deny repairs for bs reasons.

Um easy, crap tune IS the reason for spun bearings. A crap tune would cause detonations which would hammer the crank into the bearings and eventually hammer them enough to cause them to spin. Easy. Crap tunes cause detonations, detonations cause damage to the bearings...done.

I think this is another case of a crap factory tune job.

Sounds like good news to me. I'll be curious to see what compensation would be. I'd politely insist on the 100k warranty, but I'm willing to bet they'll give you a couple free oil changes or something along those lines.

Warranty fraud is someone knowingly altering a product beyond factory specifications, then attempting to cover it up by removing the parts.

Subaru, on the whole, does not deny repairs for "bs reasons".

If my "crap" stock tune is so terrible and my engine is detonating its self to pieces, why am I not able to hear it? Why has every filter I've cut open in the past 30k miles been metal free? Why is my car not burning over a quart of oil every thousand miles with this "crap" stock tune?

And please for the love of God do not post the Cobb plot. Yes people have established thousands of times that a company trying to sell their product made a chart that showed a line changing as a result of their product. Regardless of what NASIOC members may say, 14.7:1 is call stoichometric and NOT lean. Around 12:1 gives the best power but worse CO2 emissions which is probably why the stock tune does not get there until well past 2,500 rpm.

Along with what I mentioned before I would bet people using the rev limiter as a shift light are probably doing more damage than the stock tune....

Your car would have to sound like a diesel to destory the bearings through detonation. In almost all cases, spun bearings are the result of inadequate lubrication.
