My vibrating 2007 Tribeca by kharshaw

I have a 2007 Tribeca that has given me a (usually) subtle vibration that becomes more pronounced at highway speeds. It feels like driving over little rumble strips all the time. It's been doing this for the entire year, regardless of weather/temp. The other day it shook violently --I thought I had flat in rear passenger wheel. When I drove away after checking the tires, it was back to the subtle vibration. It's been into the dealer multiple times, it's like chasing a ghost.
 
Any thought? I go back to the dealer on Thursday. Do other 2007 owners have a smooth quite ride? Am I being to critical of the ride? I'm about to give up on this vehicle . Maybe I'll ask to drive an 2008 to compare the ride when I'm at the dealer...

This sounds identical to the problem we had with our '06 Tribeca...After numerous visits to the dealership and 3 sets of tires, the district Subaru Rep. maintened that our problem was inherited. We did not accept his explanation and filed a complaint directly with Subaru. Subaru decided to send an engineer to validate our claim. After almost 10 days and numerous test drives with the engineer, he finally validated our concerns and stated that it was a driveline based vibration.They replaced both front axels, rear axels and rephased the driveshaft. Still vibrated. We filed a successful lemon law claim agains Subaru and are now proud owners of a 2007 Honda Odyssey Minivan.

Ugh... Not what I wanted to hear, but thank you. How did you initiate the complaint with Subaru? Via the dealer? Or directly?

I am having the same trouble with my 2008. 2 dealers cannot fix it. I opened a case with Subabru America by calling there 1-800 number from the website. They sent the regional rep to check out my car and he told me the reason was flat spots on my tires and to increase my tire pressure to 38psi and drive it to 7000 miles. That should fix the flat spots!!!
 
Needless to say I am at 9600 miles and still have the problem. Went to new dealer for service and they told the tires were out of balance and re-balanced them. Still having the same problem though. No one seems to be able to fix it even agree that it is a problem.
 
Are you still having the issue?

Tire can be balanced but still not be perfectly round.
 
If they were flat-spotted driving on them more doesn't fix that. I think you need new tires.

Are we talking flat spotted or out of round? There is a world of difference.
 
Flat Spotted= brakes were locked up and/or car slid sideways flattening out the tread in a particular part of the tire. Very rare on street cars, somewhat common on non-abs race/track cars. Usually this happens when you lockem up and spin or lock em up under hard braking going into a turn on the track.
 
Out of Round= tires sat for a long time under-inflated and therefore are now oblong shaped. This can also be a result of broken or hyperextended cables in the tires.

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
> disappointed in the way it runs and equally disappointed in the response
> that I have gotten from Kerven and the District Fixed Operations Manager
> (Jim Hoffman). The vehicle hesitates, "surges" and overall does not run
> well during highway driving. From a stop it will sometimes hesitate and
> other times "surge" forward when the accelerator is depressed and this is
> a safety issue especially in a parking lot or other tight driving
> situations. When driving on the highway (60-70mph) the vehicle "shudders"
> and hesitates/surges when trying to accelerate or maintain speed on an
> incline. This is very noticeable and happens every time I drive it. This
> is not how a new vehicle is supposed to operate. The first time I had it
> to Kerven they told me the tires were out of balance. The second time
> they said they recreated the problem but there was nothing they could do
> about it and I was referred to Mr. Hoffman. He took
> the vehicle for a test drive and said that it is an engineering problem
> and that there is nothing he can do. Not only is this NOT how a new
> vehicle should run, there is also a safety issue involved here. If the
> vehicle cannot be fixed then I would like to return it for a refund. I am
> even willing to pay a fair and reasonable amount for the miles I have put
> on this vehicle. Please let me know how you plan to fix this problem.
> Thank you."
 
I still do not have any resolution but I did manage to get an extended warranty and a 45,000 mile maintenance agreement.

Pressure/Ear Pain by sadie13

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!!!!!!!!!!!!!!!!!
