    2012 WRX New Turbo Required at 50k miles

    I bought a 2012 WRX three weeks ago from a buick dealership and it had 48,8XX miles on it. In the two weeks I have owned it the turbo has failed, fortunately the Subaru dealership will cover the cost of a new one and installation. My question is... or questions are... 1) why would a turbo fail so early? It has a clean carfax with good service records, obviously the car has higher than normal mileage... 2) is this failure most likely because the original owner drove it hard constantly? Or is this just bad/strange timing? 3) What else should I do or have checked? By the way the turbo felt fine the first couple weeks of owning it.

    No one will ever really know except the previous owner. Maybe he didn't change the oil at recommended miles, wrong oil and clogged the banjo bolt, excessive pulling, I mean the list can go on. But you have a new one. So now you'll be the one to know what went wrong if the turbo goes, which shouldn't

    Precisely what in the turbo failed and how did you notice the issue?

    I will ask more questions when I pick it up next week, Subaru service literally just called and said "we're going to replace the whole turbo".
    I noticed the issue a day before I brought it in, there was a winding up "fan-like" noise and a loss of power in those RPM's at which a turbo is usually producing more power. I started shifting at low rpm's until I got it to where I needed.

    Would that noise be turbo flutter?
    Also make sure that they're at least checking the banjo bolt. There's a mesh filter in there that can either be cleaned out or have the bolt replaced. If you need to pay out of pocket for the bolt it's only like 26 bucks. They definitely shouldn't charge you labor since the turbo is out anyway

    Perfect, this helps. I will call the dealership and ask if they can replace the bolt for me. Anything else I should have them look at or do while they have it?

    As far as turbo related you should be good

    There's a tsb for the mesh filter in those bolts, so subaru recommends checking for replacement and using their oil flush kit every oil change. The bolts just get gunked up

    After talking to the dealer briefly, they basically said they would not disassemble the turbo simply just replace it. If the turbo failed due to a lack of oil (or dirty oil), should I be having this engine checked for sludge, or other major problems? I mean could drive a car so hard that you have major engine problems at 50k? I'll go through the service records again but from what I remember this guy had the oil changed regularly enough.

    If the turbo failed due to oil starvation the items to check would be the oil supply to the turbo itself and the presence/absence/state of any/all filter screens in that oil supply.

    Now these guys are saying they found a bad turbo "boot", and it might not be the turbo itself... this make sense to anyone?

    my turbo does not have feet, let alone boots. perhaps they are referring to the inlet tube or the tube that leads to the intercooler. I have seen a handful of thread where these tear in stock form and produce an intake leak.
