Based on information from the National Highway Traffic Safety Administration (NHTSA) website, the media may report that General Motors will be announcing a noncompliance recall involving certain 2006 Cadillac SRX; 2007 Cadillac Escalade EXT; 2006 Chevrolet Silverado 1500 Reg Cab; 2007 Chevrolet Avalanche 1500, Colorado Crew Cab 2WD and Colorado Ext Cab 4WD; 2006 GMC Sierra 1500 Reg Cab; 2007 GMC Canyon Reg Cab, Canyon Crew Cab and Canyon Ext Cab 4WD vehicles.

These vehicles fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) 110, and Canada Motor Vehicle Safety Standard (CMVSS) 120 for displaying the tire rim designation. They have an incomplete tire rim designation on the Certification/Tire Label located on the driver's door edge. If a customer replaces a wheel and only relies on the rim size designation that is indicated on the label, a wheel that is of an incorrect rim contour designation may be installed. If a customer replaces a wheel with one that has a rim contour that is inappropriate for use with the tires on the vehicle, the mounting of the tire to the wheel and/or the tire/wheel assembly may not perform as designed/intended.

To correct this condition, dealers are to install a new partial label over the existing label. Because this label can easily be installed by the customer, and to reduce their inconvenience, corrected labels and application instructions will be mailed to customers of record. Dealers will receive labels for installation on the vehicles in inventory.

Approximately 3,200 vehicles are involved and GM is working with its suppliers to obtain the required labels as quickly as possible.

GM Vehicle Inquiry System (GMVIS) information for this recall will not be available until the recall bulletin is released to dealers.
