When I close my door or put the window up and it seals, it makes an awful squeaking sound. Does anyone else have this issue? I had it at the dealer for them to look at and they were unable to resolve the issue. They said it might be the tint. Any tips would be appreciated because the sound is incredibly annoying. I just might start climbing through the window to avoid hearing the noise...

My squeaks a little but not enough to warrant me bringing it in. I, too, have tinting.

Same issue on older model, when it is hot out, soo damn loud!

I guess it ensures a proper seal. =)

i actually just threw on goo gone like "cleaning" windows and it doesn't make the noise but it makes the window grinding against the motor noise

how about spraying some silicone lubricant in the gasket? that should stop it for months if not a year.

Do so carefully and do not spray too much or it will drip.

Had the same problem on my E550 and now on my CLS. Pretty sure it's the tint. I applied Shin-Eitsu grease on window seal and it got rid of squeaks. Give it a try.

I have also noticed that the tint on the front windows is getting scratched. This also happened in my 2006. Anyone else have that issue?

Couldn't find the Shin-Eitsu grease. Tried an all-purpose grease instead. It seems to be working, just gets a little messy. I want to see how it is after a few days.

I have a brand new C300 where the front windows have an awful squeak, I just got back from the dealer where they can't seem to be able to do anything about it. No new car should have the windows squeak like this, especially on one that costs so much. I had my C280 for 16 years and loved it but I am very sorry I bought this car as I also have had a problem with the screen freezing up, something else the dealer could not fix. I am very sorry I bought this car and this will be my last Mercedes.
