Strange Noise
#46
You know I have experienced some odd noises from the rear in cold weather (below -10 C/ 14 F) where it sounded like the parking brake had not fully disengaged. The dealer told me it is a possibility but he could only diagnose the problem when we are back down below that mark.

I had a loud popping/crack sound from near the sunroof when pulling into my drive at a bad angle (my driveway is very steep at the bottom, so I usually take it at an angle to avoid scrapes). Only happened once and I have been very careful on my "angle of attack" since.
My G35 coupe did similar things that turned out to be the sunroof rails needing adjusting due to body flex. There was an Infiniti TSB about it. Once that was done, it never did it again on the G.
I wonder if this is something similar on the GS?

Tearing the interior apart to fix an intermittent noise is, to me, asking for trouble...The more you tear it down and put it together, the more likely you are to introduce even more rattles and squeaks.

The sunroof TSB did nothing for my car as it was never from the inside but from the outside rear suspension when going down the drive way or up the driveway when turning left, never with right turn.
The sound gets worse when its warmer outside (greater than 40 degrees) and goes away when cold or very cold outside (below 20 degrees). The sound IS from one of the control arm or strut.
At this time my dealer does not want to take my suspension apart looking for this sound and they are right it will ruin the car. They informed the corporation headquarters of this and the company is working on a solution and it will come soon before summer.
This noise is similar to the Lexus LS460-600 series with popping/clunk noise from the struts that were replaced with newer quieter ones.

I finally got it resolved!!! Once for all.
It is a loose bolt on the underbody that was not tightened to spec at the factory, The dealer chief mechanic heard the sound everytime going up a driveway and he says my GS was the first with the noise. He tightened the subframe bolts and the car is quiet now. I love it. No more popping sounds.

Is there any other success story on resolving this clunking noise? Mine is going in for repair for the second time tomorrow and any feedback would be appreciated!!

The rear subframe bolts are loose. I would recommend everyone to put the mechanic in the back seat and drive around the parking lot and go up the driveway, etc and duplicate that clunking noise. My mechanic immediately knew and tightened the subframe bolts after that loud clunk noise when going up the driveway when taking a full turn. The noise has been gone for more than 1 year.
