Subaru Impreza Engine Problems



  • ateixeiraateixeira Posts: 72,587
    Does he have the Blo-tenzas? Some of the OEM tire choices were awful. Same for my 98 Forester.

    Could be piston slap, too.

    I'm not sure which he has as far as tires.

    Believe me, this is NOT piston slap! If I were to start the car you would be able to hear it knocking a block away. This is loud DEEP knocking that came without warning.

    He was driving it about 65-70 MPH when a bunch of wrning lights came on all at once. Then the loud knocking started. He was barely able to get it off the freeway.

    So far, no call from Subaru.

    Ok, The Subaru Dealer called and the engine is toast.

    They confirmed what I already knew. The knocking is from the lower end of the engine and the engine will be replaced under warranty.

    They were quite good about everything and even provided a loaner car for our son to drive. The engine has been ordered and it should be running early next week.

    A fluke?

    It's been using oil but he never let it run low.

    I think so, very unusual. 9 times out of 10 an engine issue is the gaskets.

    The other 1 time it's the front or rear mail seal! LOL

    Yeah, probably a fluke. With that few miles, it is very possible that something was not assembled/torqued correctly at the factory.
  • isellhondasisellhondas Issaquah WashingtonPosts: 17,355
    It's never leaked oil unlike a Loyale we once owned!
  • isellhondasisellhondas Issaquah WashingtonPosts: 17,355
    That's what I'm thinking although you would think it would have blown up before now.

    As I said, it never sounded quite "right" to me but I wrote that off as being part of the boxer design.

    I suppose this why cars come with warranties!
  • ateixeiraateixeira Posts: 72,587
    paisan used to joke about his 80s Subies, "add oil, check the gas".

  • xwesxxwesx Fairbanks, AlaskaPosts: 8,269
    That's exactly right! Honestly, it all depends on the nature of the issue. Oil in the engine dramatically reduces friction (of course), so even a small problem that is ultimately fatal can go a long time before it comes to that due to the extremely low levels of friction. This is especially so if the car is "gently" driven.

    My wife keeps saying, "please be gentle with it - it's a new car." I reply, "Why? I'm not abusing it, so if something's going to break, I want it to happen now - not when it is out of warranty!" :P

    Honestly, this Subaru Dealer could not have been any better!

    They were fast, friendly and quick to provide a loaner they didn't have to provide.

    I taked to the Service Manager and as I expected, it lost a rod bearing which did a lot of damage.

    I asked him how common this was on Subarus and, although he did his best to reassure us it was an odd occurance, he did say that "we do replace a few engines". He alluded to the boxer design and said that "for the most part" the head gasket problems were pretty much solved.

    It's going to take a long time for our son to have his confidence restored. Getting off a dark rainy freeway full of traffic wasn't a fun thing to do.

    Again, top marks to the Subaru Dealer in Bellevue WA!

    Actually, loaners are "standard of care" in my neck of the woods. The only limitation is call in early. In case of a longer repair, a rental car is provided, tab picked up by Subaru.

    A a former (still former?) Honda salesman you may not be aware, but Subaru is a half-notch higher than Honda when it comes to post-sale customer treatment: 3/36 B-B, 5/60 P, 3/36 roadside, mainenance service loaner (need to reserve due to limited supply), car rental for overnight repairs, even their creaks and rattles, wear and tear is 3/36K (including break pads - only problem you would have to wear them to 1 mm, which is kind of hard). And it's all included in the original price - at least with my local Subaru dealer.

    Now you have me worried!

    In the last six months I just discovered my '09 OBS is going through a lot of oil - 2 quarts in the last OCI, which is 5K miles, and it was low again when I took it for the oil change. So at the last service (the 30K mile service) they did whatever it is they need to do, and now I am supposed to bring it to them the next time it needs oil, which will be in 1000 miles or less going by my experience with it so far.

    Unlike those posting above, I have never had a Subaru that consumed lots of oil, even my '84 never needed extra oil between oil changes, although it did use a little.

    And unlike the Bellevue dealer, my dealer pretty much sucks, so this could go badly. I will say this though, if the engine fails and needs to be replaced, particularly if it strands me somewhere, I won't be keeping the car.

    The only question then would be whether to buy a '12, whose looks and much improved interior and fuel efficiency have my interest piqued, or to walk away from the Subaru brand forever. I like the quirkiness of Subarus, but having a dependable and long-lasting car is more important to me than having a quirky car with a boxer engine.

    Wish me luck! :-/

    The FB series engines have separate fluid lines for the block and heads, so the head gasket problems should be a thing of the past. There are far fewer holes/seals in the gaskets now.

    FB engines go in the new Impreza and 2011+ Forester.
  • nippononlynippononly SF Bay AreaPosts: 12,669
    Too bad my 2009 isn't an FB then. :-(

    My '09 is what, an EJ? But I'm really hoping that just as people said at the time when I bought the thing, the head gasket problem was already behind them well before that year.....

    EJ25, yes.

    The gasket material itself was much improved, but when they got a chance for a clean sheet design, they kept that in mind.

    I have an 09 since mid 2008, just oil changes so far. Wife loves it, won't even discuss trading up for a new one.
  • isellhondasisellhondas Issaquah WashingtonPosts: 17,355
    Well, if your Subaru is using a quart every 2500 miles, that's not such a bad thing and it's probably well within what Subaru considers to be acceptable.

    Even a quart every 1000 miles is probably within specs I would think.

    Any car can blow an engine and I wouldn't write off Subaru because of some oddball occurance.

    Still, our son's Impreza has fallen short of what he expected.
  • nippononlynippononly SF Bay AreaPosts: 12,669
    I'm sure it's well within what every automaker considers acceptable, but it's not what I consider acceptable. ;-)

    Never had a Toyota do that, never had any of my other Subarus do that. But I have driven about 1500 miles and so far it only seems to be down less than half a quart, so that's something.

    Thing is, if it's a quart every 3000 miles now, what will it be when the car passes 100K miles and is well out of warranty? I always keep cars longer than that....

    All cars use **some** oil.

    I think you are worrying for nothing. It's very possible for one thing that they didn't get it totally full when the oil was changed.

    A quart every 3000 miles is nothing, really and there is no reason to think the consumption will increase with miles.
  • xwesxxwesx Fairbanks, AlaskaPosts: 8,269
    While I agree that it is not "catastrophic" consumption at this point, I am right there with you in thinking that it is worthy of concern. My '10 Forester consumes about a half-quart over 15,000 miles. While that is far better than I ever expected, if it were going through a quart every 3,000 miles, then I would be concerned.

    I just checked it this morning, with about 8,000 miles since the last oil change, and it was sitting just a tiny bit under full.
  • isellhondasisellhondas Issaquah WashingtonPosts: 17,355
    Man, how often you you change your oil??

    I would NEVER let any of my cars go that far!

    As I said, internal combustion engines HAVE to use some oil. A quart every 3000 miles would be of zero concern to me. That would be totally within normal ranges.

    Also, people tend to check their oil before it has a chance to drain back into the pan, they check it on uneven surfaces and, again, the people changing the oil don't always get it up to the full line.

    A lot more worse things to worry about, I would think...
