Hi there, first time poster.
I've had my 65 reg IS300h for just over 2 years, its done 75k miles (24k of those done by me) and it seems to have developed this creaking noise. It seems to either be coming from the drivers door window or the passenger door window behind and happens when you first press the throttle or brake, its also far more prominent at lower speeds. It really does sound like a creaking floor board and its literally right by my right ear! If I lower both the windows it goes away and I swear it only started doing it during the really hot weather we've been having, so my guess is that as the car flexes the glass is moving around inside the rubber surrounds and causing the creaking noise.
Any advice on how I might go about trying to sort it?
Cheers.
