2001 GMC DENALI User Comment / Complaint

I was just wondering why my 2001 yukon denali was not covered by the recall for defective abs sensors. i have had two 2001 tahoe's and a 2002 avalanche all of which were covered but my denali was not. i had to pay to have the abs sensors replaced on this vehicle. i don't understand how you can let gm get away with recalling the chevrolet brand but not the gmc brand. it's the same part number and same parts used on both brands. please reply with a justification if you can so that i may better understand the reasoning. thank you.
