The purpose of this bulletin is to inform technicians of a windrush that may occur when the luggage carrier cross rails are out of position.
Experience has shown that some customers may comment on windnoise generated by the presence of luggage carrier (roof rack) cross rails. The
disturbance becomes more noticeable as the cross rails are placed in positions over the driver and passenger seating areas.
The optimal installation locations of the cross rails to minimize wind disturbance are with the front cross rail positioned in line with the rear edge of the
rear door, and the rear cross rail positioned 50.8 mm (2 in) forward of the rear edge of the side rail. Vehicles ordered with production installed will be
placed in these locations.
Luggage carrier cross rails for a GMC Envoy XUV are a Regular Production Accessory and will be received at your dealership separately for your
installation prior to delivery.
Please use these same cross rail positions when all luggage carrier cross rails are installed during your pre-delivery inspection (PDI) process.
^
