Mazda CX-9 window malfunction with loud grinding sound on driver and passenger front windows on Mazda CX-9

Some Mazda CX-9 owners report experiencing loud grinding sounds from both the driver and passenger front windows, which may indicate issues with the window regulator or motor. These grinding noises often suggest that the window regulator is faulty, affecting the smooth operation of the windows. Additionally, excessive wind noise from the driver side window's top corner can signal a malfunction, which may be temporarily mitigated by applying pressure in that area while driving. Owners have also noted slow or noisy window operations accompanied by strange sounds like squeaking or clicking, further pointing to potential problems with the window regulator or motor. It is recommended that these components be inspected by a professional to ensure proper functionality and address any underlying issues effectively.
