My car makes a squeaking noise whenever its really hot outside (90+) only after I have driven for a while. It sounds like some thing dries up and whenever I go over bumps, I can hear a squeak from either the suspension or somewhere from the car. Any one notice this?

This only happens in those conditions so I am going to have a tough time explaining to the dealer and having them replicate this.

sounds like sway bar bushings

I'd say grease up your Sways every few months

Yea i had my minde brought in for this excate reason thinking it was a bushing in the compression rod, our cars do not have compression rods and they assured me that the noise is fine and nothing to be worried about. Of course Blah blah they didn't metion anything about it maybe being the sway bars or prehaps putting some gunk on it so I dont have to hear it anymore. If they even looked at it!

I just had my car in last weekend for this exact reason, well one of the reasons. They said they couldnt replicate the noise on their test drive and that some squeaking is normal. I asked about and greasing that might need to be done and they said there are no grease point on the car, and that everything is fine.

My 3 12 year old G35S 07 is doing the same thing. Figured there is some bushings that need to be sprayed with some silicone underneath. Now to figure out how to do that short of jacking up the front. Guess we all have the problem. I am going to an Infiniti driving school tomorrow and plan to ask someone with Infiniti there about it.
