    Echo'ing what the other guys said, this is not that unusual. The torque converter operates in two stages - fluid shear torque transfer, then a mechanical lockup for max efficiency. To promote those smooth shifts, it is not uncommon to reduce the efficiency of the fluid torque transfer a bit, making up the efficiency by going into full lock a little earlier. The downside is more slippage at idle, and a greater tendency to roll in the opposite direction when stopped on an incline.

     

    While it should be checked to make sure that it isn't defective and thus overly inefficient, there isn't much that can be done except replace it and hope for one that has slightly tigher tolerances on stator clearances, etc.

    Ken, you may not have caught my response to the posts in the other thread, but I did address this same problem on a previous car. On my Nissan, I filed the three round holes into slots, and moved the strut top to make up a few degrees. I accept that you probably don't want to do something this drastic on a new car, but if the manufacturing frame jig was off (assuming no bends to the strut itself or to the lower control arm) then you may have no other choice.

    It was a very steep incline. I tried duplicating the roll back on a number of inclines.....car held firm in all but the very steepest (a hill even sleigh riders wouldn'd attempt to sled down), then I experienced the roll back. Thanks for all your imput.....to all of you......I guess it is normal....never knew an automatic can roll back at idle.....I'll take the car into the dealer as planned just to check and make sure that it all is within "normal" range (whatever that is).

    I too did not know that an automatic could roll back in gear. I always used to think that automatics had this as a distinct advantage over manual. Thanks for the info. Atleast now you guys do not have to worry about driving behind me with your great cars. I will not roll on to you on a steep incline.

    What is the possibility of the strut top being off?

  • locke2clocke2c Member Posts: 5,038
    a lot less likely than a ball joint being tweaked / worn-out, or the lower control arm being bent.

    Thanks for the replies everyone.

     

    Steve, I did catch your earlier response and the shop did also raise a similar possibility. They also did point out that it's not something one would want to do to a new car.

     

    Colin, when you say upper strut mounts, do you mean the plate with three screws visible from the engine bay?

    keep in mind that the only time there is a direct, solid connection (non-fluid) between the engine and auto tranny is when the torque converter is in the lock-up mode. At all other times, if the roll back force is greater than the roll forward force developed in the torque converter from the idling engine, back you go.

    Ha! You should try driving our CR-V! It's totally normal for those things to slide backward even on a slight grade. Another reason I love my Subie.:-)
  • locke2clocke2c Member Posts: 5,038
    yep that's it. also called a strut top or hat. camber/castor plates replace them.

    I guess that is one of the reasons I have driven automatics by braking with my left foot. I have been doing this for 50 years (as of February).

    I don't want to unleash a blast of comments on Left vs. right foot braking, but it has always worked well for me. And yes, I have had my fair share of stick shifts...three on the tree, four on the floor and five speeds too. No problems forgetting which foot to brake with.

    Just dropped the OBW off at the dealer. Wanted to get the cooling system flushed since I found and cleaned out a lot of sludge in the recovery tank about 3k ago. Car has 25.5k miles.

     

    Also wanted to have them hear the ever-loudening differential noise my wife was getting. Figured it must be diffs because it didn't "sound" right for the auto-tranny. It was only under acceleration, and I could replicate it easily under light accel - noise went away as soon as gas pedal released. Also worse under load - uphill etc. Took a tech w/me for a test drive this morning and he heard it w/no trouble.

     

    Anyway - dealer calls me back and wanted to know why I under filled the differentials - explained to them that I haven't touched them since I wasn't planning on looking at them until 30k.

     

    Turns out both diffs were low, so I'm getting the fluid changed in both of them today while its in the shop. No leaks, must have come this way from Subaru.

     

    What ticks me off on the front diff is that when I had them flush the brake fluid at 15k I told them I thought the front diff fluid looked low on the stick. Very low, as in barely there. When I picked the car up, they told me it was fine, just hard for the average person (read: idiot customer) to see.

     

    Enough ranting - the question I have for the more knowledgeable folks is - Is there any reason for the diff fluid to be low, other than an under fill from the factory? No leaks or seeps from either diff. I've never seen a car "use" differential fluid this early in its service life. With a 100k on it I can understand it needing fluid, but at 25.5k?

     

    TIA

    Wow - "three on the tree" - haven't heard that in a long time. That's the type of shift I learned to drive on (64 Chevy wagon).
  • dougb10dougb10 Member Posts: 185
    Nice to hear anyone that remembers "three on the tree". It was my second car during my university days. The first was a '47 Olds torpedo back with the famous GM Hydramatic slushbox. That old boat either leaked or burned a quart of oil every 50 miles. My Dad got so ticked at the oil dripping on the driveway, he floated a loan for the '53 Bel Air Chevy with the three speed column shifter.

    I learned to drive at 15 on my Mom's 51 Hillman convertible that had a 4 speed shifter on the column...that was a very weird car!
  • hammerheadhammerhead Member Posts: 907
    I borrowed a '61 Apache 3-on-the-tree to collect rummage for a high school fund raiser, circa 1972-73... wish I still had that truck!

     

    Science teacher had an old Mercedes diesel 4-spd column shift - I always thought that was a cool car.

     

    Cheers!

    - at least with Ford - could actually become 5 (maybe even 6) with a Borg-Warner overdrive unit asittin' astern the manual transmission.

     

    ...and perhaps it's just me: I wouldn't be braking with my left foot.....course that most likely since my last automatic was a '57 Ford Fairline 500 convertible way back in the bronze age...Holidays best, ez..
  • crashton6crashton6 Member Posts: 245
    If you have no signs of a leak, then your diffs were low from the git go. If they are whining putting more fluid in may or may not help. I'm guessing that they'll be putting a diff in there for you. Diffs can make noise for years & still keep doing their thing. Since your car is so new I'd expect Subaru would do the job for you.

    I have an 04 Forester that has 25k miles on it. I would say that it has not disappointed me and has posed no problems whipping through everything I throw at it. Lately, I have been unable to fill up my gas tank as the fuel pump at the gas station automatically shuts down after just pumping 0.2 gallons. I have to clamp and unclamp the fuel pump repeatedly just to fill up the forester. Are there any TSB regarding this? and should I have this immediately be fixed at the dealership? Thanks for the info.
  • samiam_68samiam_68 Member Posts: 775
    There was a post earlier about the same problem. You can do a search on Edmunds. I think it had to do with the EVAP system - one of the hoses got clogged. The dealer should be able to fix it in about 15 minutes.
  • crashton6crashton6 Member Posts: 245
    I had a very similar problem on my 2000L. What I found was the lines to the evap canister were loose. I cleaned the connections up & used some zip ties to hold the lines on tight. That lasted about a year then the same thing started to happen again. This time I cleaned the lines again, but instead of using zip ties I used some small hose clamps. It's going on 3 years without the problem reoccurring. If your car is still under warranty I'd have Mr. Goodwrench fix it.;-)

    Hi everybody! I'm new to this message board and I tried doing a search for the inquiry I'm about to make with no results. I'm not very good at searching things out :(

     

    I'm hoping that somebody can answer my question even though it could be a question that's asked frequently ...I don't know.

     

    I just returned from a road trip to las vegas in my '02 Forester, obviously putting on a few thousand highway miles. I'm in the Seattle area. The Forester ran like a top on the trip.

     

    Now that I'm back home, each cold morning when I start the engine, it makes a clattering sound --sounding almost like a diesel engine-- until the water temperature gauge reaches the normal operating temperature. Then the engine returns to its normal sound.

     

    It's never made this cold start clattering sound in previous winters. Could the continuous highway driving caused this? Is it anything to worry about?

     

    Any helpful comments would be appreciated. Thanks!

     

    ~tonya
  • tonya_dtonya_d Member Posts: 2
    okay, this time the search function "sort of" worked. I did find some discussion on the "clatter" I referred to in my previous post.

     

    From those discussions, it sounds like this loud clattering sound is nothing to worry about. What makes me wonder though, is that why is it starting to do this at this time? Why didn't it do this when it was new? The first two winters, I didn't hear this cold engine clatter at all.

     

    It's hard for me to believe that all Subarus are this noisy until they warm up when the ambient temperature is below 55 degrees or so.

     

    Is it really true that I shouldn't worry about it?

     

    thanx again!

  • once_for_allonce_for_all Member Posts: 1,640
    Tonya, welcome!. Assuming you are still under warranty, I would suggest you take it by the dealer and try to get it documented. They may say it is "normal" although several owners have had new engines put in because of this "piston slap" clatter. In any case, the clatter will definitely affect resale value of your car, if not longevity of the engine.

     

    I have 29k on my '03 and had the noise one cold morning after I had hosed the engine down the afternoon before. In my case, it was a shorted spark plug wire which corrected itself after drying, and has not repeated itself.

    If you take it to the dealer (which I think you should) leave it overnight if possible so they can duplicate the conditions.
  • hondafriekhondafriek Member Posts: 2,984
    I have the dreaded warped rotor syndrome started a couple of weeks ago. I don't recall doing anything stupid to cause it, like wash the car immediately after a trip when the rotors would have been scorching hot.

     

     Although one day it was fine and the next day not. I was trying to nurse it until the weather got warmer so I could put new rotors on.

     

    It's bugging the hell out of me so I guess I will have to bundle up and do it when I get back from my visit to TENN. I will get these ones maybe turned and keep for spares, it's especially annoying since these rotors are still pristine with no scores or tracks.

     

      Cheers Pat.
  • kenskens Member Posts: 5,869
    Sorry to hear about that, Pat. How old/new are your rotors?

     

    Ken
  • kenskens Member Posts: 5,869
    Tonya,

     

    The other members have given good advice about having the dealer keep the car overnight and replicate the same conditions you experience.

     

    My first guess would be a loose belt tensioner. Another possibility would be piston slap, but typically that would manifest itself earlier in the engine's life.

  • saedavesaedave Member Posts: 694
    And before three on the tree I had two on the left foot: (For those who are too young to have driven one, that is the shift mechanism on a Model T Ford) That was a planetary transmission!

     

    And the electric starter (for those that had electric) was a foot button actuated by your left heel next to the bottom of the driver's seat.

     

    Those were the days... years before VDC...when many cars rolled over easily.
  • locke2clocke2c Member Posts: 5,038
    if the brake pads are fairly worn I'd replace them and bed them in aggressively, it would most likely fix a minor rotor issue.

     

    ~Colin
  • hondafriekhondafriek Member Posts: 2,984
    Are fairly new and they are hawk pads, warp is fairly bad as the brake pedal is pulsating badly so I will replace them.

    I was thinking of getting those Aussie rotors DBA is the manufacturer, they are getting good reviews.

     

     Ken, the rotors are, well as old as the car but have less than 20K miles.

     

      Cheers Pat.

    Has anyone noticed that the 2005 Outback seems to have an engine surge? I have noticed this on several occasions when pulling into the garage and the car surges as I let off the gas.

     

    Do I need to bring the car into the shop?
  • junior5junior5 Member Posts: 15
    Thanks very much, at least it would not involve a major overhaul of the gas tank. I usually do my own maintenance and upgrades on the subie but I'll bring it to the dealer asap this week. Thanks a bunch again!
  • junior5junior5 Member Posts: 15
    Thanks for the info, the forester has been a breeze to maintain with no problems up till this point. At least it does not sound major. Thanks!
  • samiam_68samiam_68 Member Posts: 775
    Does this happen often? I would definitely bring it to the dealer to get checked out. I bet Subaru would want to jump on it ASAP to avoid the Audi fiasco of the 80's.

    Hey Gang,

     

    My wife and I decided on the above vehicle. Now, I understand this is a 'problem' board so I can't take this as a representation of everybody's experience. However, I was wondering if there were certain issues native to the car I'm about to buy or things I should look out for?

     

    I've read about premature break/rotor problems, piston slap, leaky gussets, etc. Does anybody know if Subaru addressed any of this in later model Foresters (05's particularly?)?

    The worst thing about that car is that it is highly addictive!

     

    Buyer beware.

  • kenskens Member Posts: 5,869
    Like any car manufacturer, Subaru continually makes improvements year after year on their vehicles. I believe the head gasket and piston slap were primarily issues with the older Phase I engine used from 97-00. I haven't heard of any recent problems with the more recent models so I think they have been addressed.

     

    As for the brakes, each successive model uses larger diameter brakes and newer pad designs so I would assume that the 05s are less prone to rotor warp than previous models.

     

    It might still be a tad early in the model year to get any real statistical data on the 05s. You might want to look for 04 information here at Edmunds or other Forester owner forums.

    My 2002 Legacy Outback, 5-speed, has had a hesitation problem since purchase, but the problem is worsening as the car approaches 24,000 miles. At cruising RPMs, with constant pedal pressure, the engine hunts for the right speed/power. Often, but not always, when accelerating the engine doesn't respond for several seconds with increased engine power--i.e., when climbing a mountain pass, I can floor the accelerator when the engine is between 3,000 and 4,000 RPM, and just as I think the engine won't be able to pull the grade without down-shifting, a surge of power occurs and the power continues until I decrease the accelerator.

     

    Possibly related to the hesitation problem is an issue of the car decelerating roughly. Often when smoothly decreasing pedal pressure, the engine responds by what feels to be a total cut-off of the gas for an instant prior to settling in with the appropriate gas flow.

     

    The car has also started using oil at about a quart every 2,000 miles. I mention this for I saw one post that indicated that oil consumption and hesitation could be related to a PCV Valve. Any other experience with this?

     

    The Subaru dealer checked out the surging/ hesitation problem in the October and said on their invoice that the "engine runs as designed." They suggested that I switch brands of gas. Afterward, I did try different brands, but the engine runs the same regardless of major brand used. I have also always used at least 87 octane. It runs a little better on premium, but I feel I shouldn't have to buy the premium gas, especially at 6,000 feet elevation where I live. I also just recently tried a brand name gas treatment, but this hasn't helped.

     

    I've scanned the messages and see that the hesitation/ deceleration problems could be caused by numerous issues: sensors, PCV valve, spark plugs, and even see where I could buy an add-on that may help (Kimoto). However, I feel this should be fixed under warranty and plan to take the car back to the dealer.

     

    I would appreciate any help/ideas on how to present this/these problems to the Service Department so they will actually fixed it this time.

     

    Thanks

    Anybody else have this problem. I have only 4,000 miles on my car and recently the weather has been very cold (0-20 degrees)and my car won't turn over unless I give it a little gas in the morning. Fuel injector frozen???????? I thought subaru was built for the northeast what gives?
  • fibber2fibber2 Member Posts: 3,786
    Try this tomorrow:

     

    Turn the key to the 'run' position and wait about 5 secound before proceeding to 'start'. This gives the fuel injector pump a few second to 'prime' the system. While the injector rails should hold pressure overnight, a number of people has complained that they do not. If the lines are not at about 35psi, the spray pattern into the cylinders is diminished - basically you are trying to start cold on a lean mixture rather than the intended richer settings.

     

    Luckily, I don't seem to have this problem with my Subi, but I lived with this modified start procedure for years with an older Nissan until I got a new fuel pump.

     

    Let us know if this helps.

     

    Steve
  • c_hunterc_hunter Member Posts: 4,487
    Sounds like a definite problem to me. Call the Subaru 1-800 number and open up a case with them. Maybe they can put pressure on the dealer to take a more careful look at the problem (or even recommend a better dealer).

     

    Craig
  • zottozotto Member Posts: 10
    Thanks for the feedback. i'll give it a shot. I am going to run it by the dealer tomorrow as well.
  • c_hunterc_hunter Member Posts: 4,487
    Be sure to turn the key to "on" for a few seconds and let the fuel pump run to pressurize the system before turning the key to crank the motor. You will hear the pump run and then go off, it will make a whirring noise from the back of the car.

    I installed an exhaust tip cover when the car was fairly new. The first time I reported problem to dealer, he said "the exhaust tip was improperly installed" (too far towards the rear of car). He moved it up as the "cure". This did nothing--

    Still have the tip which is installed approx. flush with end of tail pipe.

    I love to know what the hp was on your Model T! And what were the brakes like? Mechanical? How many miles did those old Fords last?
  • rwoodsrwoods Member Posts: 129
    05beaner,

     

    I've not noticed any engine surge on my '05 OB XT but I do detect a hard impact when I first engage the transmission into drive in the morning. I guess the car idles at high rpm's until warmed up.

  • veritasusaveritasusa Member Posts: 72
    If my memory serves me right, the HP rating of a Model T engine was 22 HP.

    I know I should know the answer to this :-( While visiting my mom this week, I took it upon myself to take her '01 Forester to the dealership for it's 30K mile service

    (at 50K miles - YIKES! - we called it 60K mile service ;-)

    I told them when dropping if off that it was making a rhythmic howling or thumping noise in the rear at highway speeds and to please check the wheel bearings. Anyway, the dealership said that the bearings were fine, but they didn't rotate the tires because that noise was the rear tires. Apparently the rear is out of alignment and caused uneven wear and "cupping" in the rear tires (not the original tires -I'm guessing there's 25-30K miles on them) which caused the noise. To rotate them to the front would have cause a whole body vibration. They suggested replacing at least the two rears and getting an AW alignment. I agree wholeheartedly but my mom and I are now debating - 2 tires or 4? Will replacing only the rears cause the AWD from front to rear to be out of whack and cause problems in the differential? Or, is it fine to replace only two at a time, as long as the tires on any one axle are the same circumference? Opinions, please! Thanks all!

    Elissa (trying to save her old mom a couple hundred dollars)
  • c_hunterc_hunter Member Posts: 4,487
    Hey, we just covered this on another thread. According to Subaru, the tires have to be within 0.25" circumference of each other (only 0.040" on the radius or tread depth).

     

    If it were me, and I was going to keep the car a long time, I would get four new tires and a good alignment!

     

    Craig
  • lfdallfdal Member Posts: 679
    Elissa - we've periodically beaten this to death over the past couple of years - The rule that all 4 tires have to be within 0.25 inch circumference is something Subaru insists on to prevent premature wear of the drivetrain components. I was lucky enough to get away with this when I had to replace one tire with 5000 miles on it, everything was still within 0.125 inch.

     

    So to second Craig's post, if she's planning on keeping it for a few more years, then its probably time for a set of 4 :<(

     

    Also get the before and after numbers from the alignment shop - most shops can give you a hardcopy of just far out of tolerence things were and how well they did bringing things back in to tolerence by the alignment. This can be useful as a starting point of discussion if the car tends to drift or wander after the alignment.

     

    HTH
