Tribeca Chassis Vibration



  • morey000morey000 Posts: 320
    Yes. Still having the issue, but I haven't persued it any more. The vibration is feelable, but subtle. It annoys me sometimes, but I'm not sure it's worth the hassle for me.

    It's not really a 'flat spot' but that's the easiest way to describe it. Tires are not completely uniform, and often they have a part of the sidewall or tread that is thicker or firmer than the other parts. Even if the tire is balanced, the firmer spot is felt when driving.
    Increasing tire pressure does sometimes helps, as it essentially makes the whole tire firmer, and masks the problem. Of course, it will detract slightly from handling and ride quality.

    Many dealers will have a Hunter road force balance machine to check this aspect of tire irregularity.
  • I have an '08 Tribeca with the same problems that were evident the first day I drove it. Here is what I had sent my dealer & Subaru after months of trying to get he problem addressed:

    "> I have had my 08 Subaru Tribeca for about four(4) months and I am very

    I still do not have any resolution but I did manage to get an extended warranty and a 45,000 mile maintenance agreement.
  • We recently purchased a 2008 tribeca and have had nothing but problems ever since in regards to ear congestion/ear pain. This pain is experienced whether we are driving or not. We have contacted Subaru of America as well as the dealership we purchased it from and have been told that they have never heard of this before. Has anyone else experienced this?
  • Adding to what my wife wrote. What we think the problem maybe is that we and several others have an allergie to the off gasing of the new plastics, glues, and vinyals. I am reaching out to see if anyone else who owns a subaru has had similar effects and if you did how long did it last. I have placed carbon filters in the vents and have had no releaf. I also purchased a $250. dollar air pureifiar specific to VOC'S. My family vehicle is now my work truck that I drive with the windows down with outside tempatures at around 35 degrees. Not sure whats worse freezing or a $30.000 dollar ear ace. My experience with subaru of America !@#$%^&**#%^ lets just say I wil never buy a subaru ever again. My fist and LAST!!!!!!!!!!!!!!!!!

    Wow, and you *both* have this problem? How quickly do the symptoms appear? Have you tried occupying another of the same make/model to see if the result is the same?
  • Yes, we have tried another new 08/09 and feel the same effects and the symptoms occur immediately for not only us but several other people we have had either sit or go for a ride in our vehicle.

    We had what sounds like the same intermittent "shuddering" or vibration problem with our 2008 Tribeca. Our Subaru mechanic had us drive the car while he rode with us with his laptop connected to our Subaru. Basically, he captured some sort of readout while we reproduced the shudder. He sent this information to Subaru. Subaru told him that they knew about the problem and were working on a fix. Six months later, our mechanic received direction for the fix from Subaru. I will try to explain what they did, from looking at our service summary sheet.

    I am not mechanically inclinded, so bear with me. It looks like they replaced the torque converter, the turbine speed sensor &/or o-ring. He also mentioned that he "re-flashed" it. I think he means a software update. These repairs were just performed yesterday, so only time will tell if it is the correct fix. If you require more specifics, our mechanic's name is Tim and he works for Schumacher Subaru in West Palm Beach, FL.

    I hope this helps!

    Now that a month and a half has passed, was wondering if the replacement of the torque converter, turbine speed sensor, and/or o-ring has correct the issue? I am having the same issue with my 2008 Tribeca.
  • vle3vle3 Posts: 3
    It seems to have worked. Neither my husband nor I have experienced the vibration/shuddering since the replacements. Typically, we would experience them several times a day. We feel like the problem has been corrected. Let me know if we can help further.

    About what speeds did the vibration occur? And, was it speed sensitive?

    Do you know if there is a TSB out on this problem?

    My vibration is still there, and it is subtle. So, it's not too bothersome, but I do notice it from time to time.

    I've also noticed that when the vehicle is cold (not real cold, but within a few minutes of starting in the morning 30-60 degreesF), I get hesitations. No check engine light though.

    Thanks for the info. I have contacted my dealer and am waiting to hear back from them. I also get the hesitation mentioned in one of the other posts.

    Just to provide an update... I was experiencing the vibration on my 2008 Tribecca. I complained to Subaru and was contacted by a Sales Manager. She arranged for the torque converter to be replaced (no charge). It seems to have done the trick.

    Glad to hear they helped you out. Odd fix, but hey, it worked!
  • I recently had the same problem with my 2008 Tribeca. The dealer replaced the torque converter, O-ring and sensor last week under warranty. So far no vibration. Thanks to all that posted their experience with this issue.
  • I am in Australia and have recently aquired a Tribeca. The problems that are expressed in your forum is also in the vehicle out here. The first vehicle I had shuddered, felt like it was missing when on highway driving and I complained that much Subaru gave me a new vehicle after they replaced the torque converter and a number of times doing upgrades to the computer. Well the same is happening with this new vehicle. It has only 8k on it and it is a dog. I have complained again to Subaru Australia and they do not want to know about it. I am now looking at trading in the vehicle foe a new Liberty its that bad. I would never endorse this make of subaru to anyone. They are an absolute joke of a car. Total waist of money.

    Just an update. It is now December of 2009 and we are still "shudder free" since the fixes noted in my earlier post. We love our Subaru!
  • Well, My Subaru dealer are as frustrated as I am.
    I have had three torque converters, numerous other parts and software upgrades.
    Also more recently "anti-knock sensors". The dealer phoned me that the car is still doing the same thing. Subaru Canada seems to be grasping at straws and based on the entries in this forum, I would have to think that they are about to have a major request for recall of this vehicle.
    I am going to ask them to take it back.......This is now 30,000km and over 1 1/2 years of this CONSTANT problem. Enough is enough!
    I just feel badly for the service people, who have tried everything and have been as helpful as they can.
    Good luck to you all! :mad: :lemon:
