Active Fuel Management (AFM) lifter failures, timing chain breaks, and oil pump failures are attributed by dealerships directly to the GM cylinder deactivation system. The same AFM failures are reported on the Chevrolet Tahoe, Chevrolet Suburban, Cadillac Escalade, and Chevrolet Silverado. Separately, two of this generation's recall campaigns are the same ones issued for the Chevrolet Silverado, which shares its platform.
