alright then. i dunno how cold it gets there. was just an idea....

initially our rubbish low octane fuel was fully blamed for the failures, but clearly it's not the only reason.

95 RON is the best you can buy at the pumps. and if you buy a dodgy/non-reputable brand...it's 93 RON you're getting.

stuck in the dark ages here, mate

Opinion here has it that the map is dodgy as the car comes from the factory, as it is most usually pistons 2 & 4 that fracture. But once you re-map the car Subaru here will reject any claim. Rightly so in my opinion. I wouldn't support a warranty on an APi engine if some Tom, Dick or Harry mapped it. We have 2 / 3 mappers that we use and trust, the rest are who they are, but we will not support our warranty on anyone other than our selected band.

I suggest that the Seth Efriken map is different, Better ? or just different. and that part counteracts the regular problems that we have here in the UK.

lol @ Seth Efriken.

The map on my hatch was good, i gained a lot of power from it too. It was Italian software, I forgot the name. The tuner also knew what he was doing. The other other software I know of for remapping for 95 RON, is Ecutek. The guy said I will gain no power from it, though.
So, it's the same story as you guys have there. Get a good tuner sporting good software.
The americans also complain about the rubbish OEM map.

I think it's unfair to call it a rubbish map. Remember it is a catch all map, for all types of driving, for all types of drivers, in all types of circumstances; weather, humidity, speed, temperature, fuel etc etc.

So it has to have many compromises built in and whilst it doesn't do what ' we ' want it to do, it is what it is. It has to be that way.

I have some sympathy with Subaru IM, insofar as, they have to be suspicious about why the engine has failed [ as would we ] and whilst I agree that they are not treating customers very well who have a genuine failure they have to be consistent in their investigations.

None of us have a concrete answer about why the pistons fail [ they do, no doubt about that ] - but EXACTLY why, is a matter of discussion. In the scale of a manufacturer, it is actually a small percentage out of all the cars they sell.

In which case to upgrade all cars with a 'better' pistons is hugely expensive in a world of tight margins and costs. Cars manufacturing costings are measured in pennies and to stick in ' better ' pistons at a cost of say £100.00 per car to the manufacturer is a crippling cost add on. When the data shows that only 3 % [ say ] of cars have failures, why would you do that? Wouldn't it be cheaper to pay up and fix the dodgy ones that you absolutely have to fix and argue over the ones where doubt about use and maintenance come into play?.

I better get my fireproof suit on I think. But I believe that above to be a reasonable argument as a manufacturer would see it.

Have you copied and pasted that lot from a Subaru PR leaflet

There is absolutely no excuse for what has gone on with Subaru. The failures, the treatment, the spin, the lies are why many have walked away. Its total false economy to take the approach, let them fail and we will fix only the ones we cannot wriggle away from.

Of course they have a right to investigate and reject certain claims but we all know there is more to this than a limited number of failures on abused cars. I would also say that I bet Subaru would love a failure rate of 3% on 08 > cars.

They have worked quite hard to put themselves in a position where they deserve to take the flak from both barrels and that's what they should get from the majority of 08 > STI owners.

Tick tick.......boom (at the expense of the customer). It's all so wrong.

I have no reason to defend them at all. I am just trying to put a perspective on how they might think the problem through, relative to what their customer is expecting.

Don't forget, in our little way at APi, l still have to look after our customers and support them and maybe l go [ I know we do ] further than they do, to keep a reputation. But from my point of view I have to police warranty questions and l probably accept more than l ought to, because l am that way.

I know that other tuners do the same, just to keep the peace. At large institutions like I M you are dealing with an employee that may be interpreting a rule to the letter [ he has little choice ] and you'll never get to a person that can make a decision to alter or override that rule. They hide behind the corporate face.

Come here and you can sit in my office and yell at me. I might yell back and if necessary , after a ' frank exchange of views', a solution is reached and we both have bloody noses, but no one has been killed.

I will never be back.

but you can't be sure, as no one has the answer to the issue/pproblem.

and not every car has the problem.. you only read about ppl having problems.

in the bigger picture how many 2.5's (hawk/hatch) have been sold?

how many do you/we know about with a piston problem.
(I'm not talking about other problems as all cars can have a problem along the line, my wife's ford focus 1.6 TDCi and my siste'rs Golf GT Sport 2.0 TD both have had turbos break and replaced).

It makes little difference if your going to get the problem or not, the seeds of worry are truly planted in your mind every time you use the car, your not going to push it to the limit the car can take, just in case it happens to yours, which after all your its only modded & thrashed ones that fail attitude, I can say after doing dozens of failed Hatch engines, only a couple have been modded, the rest were std, same goes for the Hawk as well.

It has spoiled a good car & has not done Subaru any favours in this country or several others, with the shocking treatment of loyal customers, which will never come back.

Yes, fair enough, you only hear the bad stories - but my god, there are an awful lot of them.
Just have a look on scoobynet's hatch thread.

Look at the number of hatches that have had to be 'fixed' by the respected engine builders, plus its well know that the pistons are a weak link.
Locally I know 4 hatch STI failures, but I can't say that's 4 out of x.
One of those cars in particular was well looked after, and you could count on one hand the number of times it might have hit the limiter.

Subaru UK have burnt their bridges with regards to any loyalty that might have existed, due to their disgusting attitude towards those that had failures.

Hawks didn't have issues to the same degree as that of the hatches, so don't count those.

Buy my rebuilt forged 2.5 from this thread.... https://www.scoobynet.com/subaru-par...ged-ej257.html
Get yourself some cosworth head gaskets, get someone who knows what that are doing to clamp the heads on, then forget about all the problems in this thread

*essay warning*

I've been off here / inactive for a long time since I offloaded my 09STI in 2011, but I've always watched this & the owners thread updates. The reason I let mine go was definitely the constant worry of failure, & I didn't have the funds to upgrade internals & assure no risk of ringland failure. It was a difficult decision & I still miss the unique character of the car

It's been depressing to read with fairly regular frequency the core contributors to both these threads reporting their engine failures one after another.

This issue has never gone quietly away as I'm sure IM would have hoped, and the nose dive in enthusiast interest in the GR series in the UK must have contributed to their decision to stop importing the Impreza. I would bet my Subaru WRC baseball cap the reduced likelihood of loyal buyers repeat purchase was a big factor in their decision, although of course exchange rates were the main driver.

Key point in my opinion is the failure to eliminate the obvious design fault (even if it is a 'low' failure rate. 2% is low, but this is not an annoying rattle or faulty relay that is easily sorted, it's a major consequence failure if it occurs ).

This surely can't be a cost argument? The extra £100-200 on-cost of fitting better pistons at the factory would surely more than outweigh the life cycle cost of the repairs to Subaru and its customer-facing dealers, never mind the lost sales potential. In fact it would probably make sense to pass on the on-cost (plus margin of course - 10-20%?) in the list price, especially since Subaru would have no problem whatsoever using the forged pistons in marketing claims!

Oh and btw when I stopped sulking after 09STI ownership I bought a GT86 which is I'm sure you'll all know a BRZ twin. I would not risk buying a BRZ based on IM's reputation, and sure enough my experience with Toyota dealers with a warranty claim (HP fuel pump sounding like a cricket on idle!) has been excellent. Toyota uk's attitude to upgrades (some dealers will fit & warranty aftermarket performance upgrades), their treatment of customers (I've been on a track day at Oulton Park with their cars) and recognition of the power of the enthusiast on this car is refreshing. The only worry I have is how often I have to replace the rear tyres.

I really miss the power, but definitely do not miss IM.

I have to agree, I myself had been a Loyal Subaru customer for 17 years with 4 brand new cars and 1 Demo. Build quality improved over the years but the 330S was the worst mapped car I have owned, but mine fail at 18 months old with 29k on the clock. Subaru UK/IM didn't want to know, so did the olny reasonal thing and sold it and brought and Audi.

Not saying I wouldn't buy another Subaru but it would be a 2.0 litre car not the dreaded 2.5 to be used as a weekend toy.

I now i will probably get flamed buy the haters but, once forged pistons are fitted, arp studs and cosworth gaskets the 2.5 is actually a great road car engine with usable power everywhere in the rev range. The engine had great potential to be so something quite special. Just a pity subaru cut corners. They're not the only engines with issues though, i have heard of VXR's, jags and mercs with similar issues. Watching a car show the other day i was horrified when they were talking about buying a second hand Bentley R turbo. They said check the head gaskets as they all seem to fail at 50k and cost 3k to fix.

You won't get flamed

Most agree that with the upgrades it's a good engine. The haters,hate simply because it has to be done to a modern £30k car. This and the way Subaru body swerved the issue and failed to be honest and support there customers.

Yes, but a good proportion of those are JDM lovers who think that anything that isn't twinscroll is below their contempt.

The rest of them are newage and classic fans who hate it because a hatchback isn't an impreza. In my eyes the hatch is a far superior car to the newage.

Indeed, had they come clean then things might be different.

However this 2% failure rate, or whatever ever other bullsh!t number magically appears isn't right.

Just look at the number of failures in the USA - infact Subaru of America pulled the plug on STI sales at one point due to the number of failures.

Default Similar problem?

Bought an 330s, 2010 with 30k miles just 3 months ago. Wish I didn't was not aware of any problems.

I've recently found out I need a new short motor after 2 pistons, crankshaft and other damage. The Subaru garage told me it had a new engine at 26000 miles (8 months before I bought it) under warranty. I've only done 3000 miles in it.

I'm currently talking to the dealer I bought it from, who are doing an independent report and hope to have that soon.

Here is the list of parts the Subaru dealer tell me need replacing but they suggest replacing the short motor.

PISTON RING SET
PISTON
ENGINE GASKET AND SEAL KIT
BEARING SET CONNECTING ROD
BEARING SET CRANKSHAFT
CRANKSHAFT
COMPLETE OIL PIPE
COMPLETE FLANGE BOLT
BELT TENSIONER ASSY
OIL STRAINER ASSY
OIL PAN ASSY
OIL PUMP ASSY
OIL FILTER
OIL COOLER ASSY
STAY TURBOCHARGER
EXHAUST MANIFOLD GASKET
TURBO INLET GASKET
TURBO OUTLET GASKET
EXHAUST OUTLET JOINT GASKET
MOBIL 5W30 FULLY SYNTETIC OIL
SUBARU ENGINE COOLANT

Sounds pretty similar to all the problems in this thread to me.

Obviously I hope the dealer I bought it from will resolve the problems but surely a new engine replacement must last longer than a year and 8000 miles so subaru could also be liable for the repair. I wondered why the subaru dealer were not being helpful in telling me what the cause of the problems were

Just to clarify,I bought the car from a Mercedes dealer and took the car to a local subaru for diagnosis after blue smoke and loss of power.
