My car makes low pitched squeaking sound when I drive on uneven road or if I turn into an incline, I hear a pop. If the windows are low, there is no squeaking. I figured they would rub against each other and make that sound, but the pop comes from the roof. Has anybody experienced that? Is that normal or should I have my car checked?

got exactly same problem. Do you have panoramic roof?
the sound comes from it. better to go to the dealer and solve this issue or at least get a advice what to do. I will go to dealer about this problem next week.
however, i hear this problem from many people only who have pan. roof.

Yes, my car has a panorama roof. I'll take it to the dealership tomorrow. Has your car made squeaking and popping sound from the first day, or you noticed it much later on?

i really do not remember. i bought it in 2010, and not too tong ago on 10,000 ml i have noticed it.
please keep posted after you visit them.

They greased the windows and the panorama roof. When I drove off the dealership, I didn't hear any squeaking. I parked my car in the sun all day and when I got in it, the temperature was 100F. When I drove, I heard a little bit of squeaking but not as noticeable as before.
The dealership told me that I didn't open my windows or the panorama roof very frequently and they needed greasing. So take your car to the dealership for greasing

this is what I thought needed to be done. As there is no other excuses for it. I will take it next week, having my bumpers painting now..
Did it take long for them to fix it?

They fixed it the same day. I dropped it off at 11:00AM and they called me at the end of the day to tell me the car was ready. I picked it up the following morning.
