Subaru Forester Engine problems

I would like to know if anyone has experienced the endless problems that I am currently facing with my 2002 Forester L.

My engine light went on about a month ago and finally when the ride was 'bumpy', feeling like it was going to stall, I took it in to Subaru to have it checked out.

They found numerous problems.. and at only 120000km, they told me I needed a new head gasket, a new clutch, and I can't remember what else, for a grand total of $2700. Not quite what I was expecting... but no choice, had it done.

Exactly one week later, on came the engine light. I took it back in, this time I was told that I might need an oxygen sensor. They reset it, and the next day on came the light. This time the bill was $340, and the service manager also told me that they found another problem with the 'clutch cover....' part alone cost $200, but they didn't charge me... thanks.

I kid you not, one week to the day, on came the blasted engine light. This time it was a corroded wire under the gas tank... the bill, $180.

It is now two days later and my car would not start today. I had someone push it and we got it to start.

Needless to say, I'm not impressed. Is this just a nasty stroke of bad luck or am I being snowed, or is there a history of these problems.

I'd appreciate any feedback, including how to avoid losing my cool at the dealership tomorrow.

I kid you not, one week to the day, the light came on

    A well cared for 99 Forester with under 60K has started losing several quarts of oil between changes - there is a pump clicking noise when it is low. No signs of drip under the car. Anyone seen this problem? Seems a bit early for rings or valves.
    Thanks

    Sorry to hear about your more-than-a-fair-share of problems. It might be common to experience one of those issues, but certainly not all on the same vehicle.

    Call 800-SUBARU3 whenever an issue like that creeps up that might be related to a problem you had in the past. See if they'll cover it or at least help you reduce the cost in some way.

    You might be past the 3/36 warranty, but if not, consider a Subaru Gold warranty if you will keep it longer.

    Having said that, I don't think your experience is typical. I have 80+k miles on my '98 and have one visited the dealer once, for a recall years ago.

    I purchased a 06 Forester last November and have had problems with the idle when the engine is cold. The Forester is a base model non turbo with the standard 5 speed. Originally the first week we had the car it suddenly lost power and when I engaged the clutch and pulled to the side of the road the engine died. I was able to restart and the car ran fine all the way to the dealership. The dealer wound up replacing the intake plenum stating that the wires we dammaged inside the plenum. After the replacement when it is cold out below 40* F. say the engine once started will rev to around 1500 rpm. Once you start driving the car and the car is in gear and the clutch engaged the engine revs anywere from 2500rpm to over 3000rpm! We have taken it to the dealership multiple times and have involved the are rep who stated that this is a problem that is occuring in thousands of 2006 cars and tried to blame the drive by wire system along with new changes to the emission set up in the car and basically stated that there is no fix for the problem and does not feel that this is a safety issue even though it had been brought to his attention that the car also accelerates on downhills while it is in this high idle mode. The idle does drop to aprox 1000rpm after the temperature guage has reached 1/4. Has anyone else had this problem? Has anyone else had better success with a repair. I do think that this is a safety issue when a car actually accelerates on its own requiring you to drag the brakes even on a slight decline to control the car accelerating on its own.

    That definitely doesn't sound normal. I've only driven an 06 auto, though, not a manual.

    this is an emisions feature that subaru built into the computer programming to warm up the catylitic converter and car sooner? My old subaru had a high idle on cold days that settled down after the car warmed up.

    That's a good year to shop for, by then the wheel bearings were more robust (03+) and the head gaskets were also resolved (02+).

    Thanks for the replies, very helpful. I was most concerned about the head gasket issue. Since I had left the original message, I did a little more research and that surfaced, along with the "piston slap" issue. I couldn't tell if it had been resolved or not. Out of curiosity, how was it resolved? From what I read, it sounded almost like an inherent design flaw with the 2.5L motor?
  • ateixeiraateixeira Posts: 72,587
    Piston slap never developed a pattern the way head gasket failures did.

    For the latter, Subaru issued a TSB and sent a letter to owners of 99-02 models asking them to take their cars into their dealer. The dealer added a coolant conditioner and put a sticker on the radiator notifying any future service tech that the coolant had this conditioner in it, so it would not be drained and filled without the stuff.

    Owners that did that got a 8/100 warranty against HG failure. So Subaru address the issue pretty well. From 02 on they used revised head gasket materials.

    The only other thing we truly saw a pattern of failures with was the rear wheel bearings on 02 and earlier Foresters and 01 and earlier Imprezas. Subaru switched to a more robust design with the next generation of each car, and again we have not observed failures (at least regularly) since that time.

    If you read Consumer Reports, you will notice sudden improvements in the Drivetrain and Engine scores right around 02-03, so their data tends to agree with what I've observed reported here on Edmunds.

    For the past few years Engine ratings are all "Much Better than Average", which ought to show that piston slap is not common, though it does exist in some circumstances.

    My wife's '03 Forester has 30,000 km and dealer will be shortly replacing just 2 pistons, etc to cure noise problems. Does this make sense to owners who had repairs ? I see references to short blocks by some folks out there ? Any comments on the success of repairs lately ? Comment from factory rep was the repair is being done early and may not be successful as block not fully "seasoned".This car is 41 months old !! Comments & ideas welcome - Waterloo
  • This topic was briefly visited quite some time ago (see message 1056 from Karen56). I'd like to revive it. I have a 2001 Forester. It periodically releases an intense gasoline odor in the passenger compartment. It is distinctly gasoline (not rotten eggs or some other odor). It happens sporadically. It is not related to season, driving, filling up the tank or any other logical thing I can identify. The odor lasts for a day or so, then disappears. This happens probably once or twice a month. Again, I can discern no pattern. I've seen no signs of leaks and no change in fuel consumption. Engine performance is fine. No code lights thrown.

    My questions:

    1) anyone else experience this?
    2) can someone describe the fuel vapor capture/use system in detail for me (e.g., lines from the tank fill tube to the engine, etc.)?
    3) where is the charcoal canister for capturing fuel vapors located on a 2001 Forester?
    4) is the canister easy to replace?
    5) canister replacement cost?
    6) any other thoughts, ideas, suggestions?

    I'm new to the forum and all help is appreciated.

    Thanks

    Welcome to Edmunds SalemForester.

    Is that Salem Oregon? (I know there must be 50 Salem's out there). Just wondering if you can pump your own gas or not - no self serve in Oregon.

    Do you ever fill-up with the engine running? Someone just pointed out this morning in another discussion that doing so can mess up the evap system (but usually that would also turn the check engine light on).

    Sounds like this is going to be one of those animal, vegetable or mineral problems to solve. :surprise:

  • Hi, Steve

    Thanks for the welcome.

    Beautiful Blue Ridge Mountains of Virginia.

    We self-serve here. Never pumped with engine running.

    The reason I brought up charcoal canister is that I've heard that overfilling can saturate the canister with vapors. I'm not sure that's the problem and I don't want to prejudice any other possible explanations.

    Can you direct me to post about fill-up with engine running?
  • Stever@EdmundsStever@Edmunds YooperlandPosts: 38,927
    I've heard that too about the canister; another reason why people shouldn't top up the tank. You'll have to wait until someone more knowledgeable than me pipes in with some suggestions.

    Here's the fill up post:

    Can't post a picture of the Subaru fuel system but try:

    If the link doesn't work I could email it to you ?
  • Thanks lakepop. I got the picture. It helps. I'm going to take a little time to look it over.

    Sounds like a problem I had a few years ago with a Beemer. There was a problem with a leak within the fuel injection system.

    Symptoms - would happen once a month or so, no apparent pattern as to when it would happen. After a year it seemed to occur more frequently on consecutive days. When I checked into it, the dealer found a service bulletin or recall that fixed the issue. Gas would spray out at high pressure, vapors would enter the cabin via the ventilation system. Replacing a part (fitting? tubing?) within the fuel injection system fixed it.
  • Good news...I have the answer!! And, as typical, almost entirely by accident.

    For those who want the short answer to my smelling gasoline in the passenger compartment, here it is. (The "whole story" follows.)

    The answer: disconnected crankcase blowback hose.

    Here's how I understand what the mechanic said. The crankcase blowback hoses (there are two; one on the passenger side, one on the driver side in the engine compartment) recycle back into the engine gas vapors that accumulate in the oil crankcase. This saves gas and lessens emissions. If the hose(s) get disconnected then the gas vapors "blowing back" from the crankcase are released into the engine compartment where they can be sucked up by the interior ventilation system (heater) and pumped inside the passenger compartment, hence, the strong gas odor inside.

    The mechanic said that whenever he gets a gas odor complaint the first thing he checks is the crankcase blowback hoses. They can be knocked loose by anyone fiddling around the engine block, especially if removing spark plugs. Anyway, the Subaru mechanic quickly and easily reattached the disconnected hose and checked the other one as well. It took 3 minutes. Graciously, no charge at all.

    So, that's the short answer for anyone who smells gasoline in the passenger compartment.

    Does this make sense to any technically inclined readers?

    Now, a little more elaboration for those who like the "story" part.

    How did I even stumble on this? Well, I was peering under the hood trying to make sense of the gas vapor control system per the diagram that lakepop referred me to. There is also a diagram pasted by Subaru on the inside of the hood which I hadn't noticed before. My primary mission was to try and locate the charcoal canister for reasons I mentioned in the previous posts.

    Well, anyone whose tried tracking the maze of hoses and metal pipes on the engine knows how daunting it can be to follow everything. Making it even more challenging is the fact that many hoses and pipes disappear out of view passing here and there around the engine. So, I'm bending over and twisting this way and that to follow everything. The fact that many of the tubes drop down in the shadows and into darkness makes it even more difficult. (Obvious hint: the mechanic pulled out a pen flashlight to be able to see the hoses.)

    I wasn't using a flashlight but it was a very bright sunny day. I happened to notice a tiny, bright metal shiny glint that caught my eye. I could have easily ignored it because it was difficult to see exactly where it was deep under some tubes and hoses. When I looked closer it looked only like a non-descript hole. Again, I was tempted to simply ignore it and go on tracking down the charcoal canister. But I took one more careful look and what I realized is that the shininess was from the top of a short open metal tube that had liquid around its lip causing it to glisten. Then I noticed oily liquid stains all around the tube and on the engine components. (Had it been a cloudy day or had the car been parked in the shade I would have never seen a shine!!)

    Not being a mechanic, my first thought was "Am I missing some dip stick?" I thought the tube looked like a dip stick tube. I thought that it might be the front differential dip stick. I wondered if the last time I had an oil change the service agent checked my fluids and forgot to re-install a dip stick. So, seeing all this mess I went to the Subaru mechanic thinking I was going to need a replacement dip stick. In the maze of hoses around the tube top I did not notice a short piece of rubber hose hanging loose near the tube. It was covered with black oily residue. As I found out, that gunked-up rubber hose, with an attached pinch clamp, was the crankcase blowback hose that had become disconnected from the tube coming from the crankcase. The blowback contains a small amount of crankcase oil and it was that oily residue that was all over the area.

    So, now you know "the rest of the story."

    Feel free to supply your own moral / lesson learned!

    Thanks to everyone who responded.

    I hope this helps other folks.

    Good save.........I was thinking canister....but it was still an easy fix at a good price.

    All the Subaru forums I follow are loaded with people anxious to help...so don't ever feel bad about looking for inputs. Also THANKS for posting the solution....people tend to forget their role in the info loop.

    Hi all, I have a 2004 Forester XS Premium with 68k miles on it. I've been quoted 350.00 to replace the timing belt. I'm in the Germantown, MD area and am wondering if other have similar experiences. If anyone is in the Montgomery county, MD area and has done better please let me know.

    Thanks
    Ellen
  • mckeownmckeown Posts: 165
    Ellen, unless there is a problem that requires the timing belt to be replaced, it's replacement interval is 105,000 miles.
    Since I don;t know that area, I'm sorry, I can't suggest anyone, I know here on northern NJ the dealers get from $650 to $800 just for the Timing Belt replacement. Some also replace the Water pump and other pulleys as preventive maintenance.
