I know that a spun bearing doesn't guarantee a seize. But if you drive with a spun bearing for long enough, the resultant heat can cause a seize and cracked blocks/heads etc, but I guess you make a good point that 09 owners in the bad range would be attentive enough to engine sounds to that they'd catch it prior to a seize.

I've definitely heard/seen of numerous engines that seized after high performance usage of an engine with a spun main bearing.

i'm not sure if thats a safety concern,.. it seems alright to me,.. you put the car in neutral and you have the wife and kids push it to grandma's while you steer...

Well, if you drive on a spun bearing long enough, and then get in a 10 car pile up... That's just natural selection doing it's job..

It can only take less than 1/4 mile before the engine seizes by the way: 87 Fox body 5.0L with a roots blower. My friend knew the internals were approaching the end of their life. Anyway, a little more than half way down the track he said he felt like the car was slowing down and then the wheels lock up shortly thereafter.

The 10 car pile up was hyperbole.

^ +1 to the relatively short distance in which the engine will "seize" or otherwise die.

One '09 Forester XT owner (not me, although our engine suffered a spun bearing at approx. 4200 miles, and a longblock was replaced under warranty) barely made it from the start of a typical off-ramp, to its end, before the vehicle simply died.

Well, my '09 WRX 5-door with 08/08 build date made it until 16,500 miles without any problems. Then, without warning...

I woke up one morning and decided to get rid of it. Life is good.

I posted awhile back about how my car was fine... well not so much. I blew my motor about 4 weeks ago, took em about 2 weeks to fix. The dealer didnt ask many questions, and replaced my long block under warranty. Although they did give me the stink eye and repeatedly.

anyways,

babbylonmon
Dealer: Wentworth Chevrolet and Subaru (Portland, Or)
last #s of the vin: 504373
build date: 09/08
milage: ~9800

The new engine seems to be running fine, except i seem to have developed an increase in afterfire. I have spt cat back, and a k&n drop in air filter, but I had those before the motor blew and I did not have any afterfire then. I'm not that concerned about it, as I plan to be @ stage 2 by the end of next month. Yup thats my experience

Sorry to hear about it - my 09 went at 7k or so and same interval more or less to get it fixed (although boost control solenoid failed when I got it back...)

I've never read of an 09 getting mods before the inevitable engine failure. How big was the difference before and after the spt cb and k&n?

Hello,

I've just become a new owner of a white MY09 Impreza WRX VIN ends with: 8254##). I'm a second owner of it and bought the car (online). It has 3400miles now. Hasn't checked the car yet because it's going to be shipped to europe, so I'll pick it up after a couple of months. Anyway I'm a bit worried about the car service history (or possible engine issues).

I've read a lot about the engine problems (the spun bearing problem) of MY09 WRX's (unfortunately after I decided to buy it), but it also seems that everybody/most of people that had the spun bearing problem had a built date of July or August 2008.

I'm just worried if my car is free of possible engine failures. In fact I can not check the built date on it so I can only type VIN here (8254##). It seems to be a high number? What do you think? I'd be glad to read your response because the US warranty is not accepted in Europe /in case sth (knock on wood) goes wrong with the engine.

Cheers,
Adam

P.S.
Sorry for my poor english

You should be fine for the bearing issue based on that VIN. It probably has a 3/09 or 4/09 build date. Most of the engines that blew were a VIN of 8051** or less based on page 1 of this thread.

Do we know if these blown motor issues have been resolved for the 2010 WRX's, or is it still too early to tell?

Agreed, i've read through this whole thread and I still missed it!

What's the best way to find out the build date of a car is without actually being able to physically look at it/the door?

I think you can derive it from the VIN.
