The official notice
Defect
On certain K1500, Astro, Safari and Suburban vehicles, corrosion of the composite front brake rotors could cause separation of the stamped steel centre section from the cast outer rotor resulting in complete loss of braking capability for the affected wheel and a partial loss of front braking. This would increase stopping distances and could result in a crash without prior warning.
Safety Risk
No risk description available.
Remedy
Dealers will replace both front brake rotors with rotors having a corrosion protective coating.
