NOISE FROM ROOF RACK CROSS BARS

Applicable Models

Some customers may experience a resonances and/or a whistle that is     
generated by the roof rack cross bars, these noises will vary           
according to vehicle speed and wind speeds.                             
                                                                        
Although the wind turbulence noise generated by the roof rack cross     
bars should be considered normal, Mazda realizes that some noises       
are an annoyance to some customers. Improvements were made to the       
front cross bar to reduce a resonance that occurs at approximately 35-  
40 MPH by adding additional wind checks to the face of the cross bar.   
The lower edge of the bottom wind check that runs the length of the     
cross bar was trimmed to eliminate whistling.

Please confirm that the cross bar(s) are installed with the wind trips
