07 H3 Shakes on highway at 65+ mph, normal?

[amyandmark3]

Hi, Hummer newbie here, sorry in advance for what is probably a dumb question.

We just bought a 2007 H3 with 57k miles. Very pleased with it except we notice that it shimmies/shakes a little once we get it above 65 mph or so. The tires are Good Year Wranglers and look to have about 1/2 of their life left. Is this a common characteristic of the H3's drive at higher speeds? Or should I complain to the dealer that we want this looked at / fixed? We just picked it up today and have no recent experience with 4 wheel drives, so not sure what to think. Thanks for any help and/or opinions.

I would have them check the alignment, front tire balance....and the front tires. I think there were some bad wrangler tires.....check the old threads on the tire problem.

Thanks Hummer3. I am also in Indy, bought this from Carmax on the north side, hoping they will fix it for free.... if not, we have 'til Thursday to back out of the purchase. Not sure we'd back out just for this issue, but it would be nice if they take care of us.

I've got the same thing. I'm gonna have my dealer check it out next week. I noticed it quite a bit going 70 on the HW two days ago.

Nice Tactical BTW.

Also, I don't know if its just the angle of the pic, but your tbars appears to have been cranked. Maybe the PO did this and did not get an alignment afterwards. Pic might be deceiving me though.

I have heard carmax is a good place for customer satisfaction.....

have them drive it and feel the problem......then ask them if they should be selling something with that problem.....

Thanks again for the comments fellas. I will give my Carmax salesman a call tomorrow to see what he can do for me. addict, not sure about the tbars, but here's a couple more views:
