I have this LS TAHOE for 3 weeks now and there is squeky noise in the interior which seems to get louder than before when driving.
Does anybody have this problem?
How did the dealer fix this problem?

I just cant believe a few weeks old, squeks like a few years old car.

 

Yep, same thing here. I'd say you'll probably have to get used to it. I mean you have to expect some squeaks and rattles on big SUVs and trucks (in my opinion). I've heard similar if not worse noises riding in new Ford F-250, 350 and a Nissan Armada.

Don't know of a fix unless you or the dealer can pinpoint something that can be tightened or lubed. Good luck.

 

I have noticed the same thing on my Tahoe. Kinda sounds like a foam cooler rubbing up against something!?!?!?!?! I think I'm going to have to live with it!!!!!!!
