I own a 2011 Avalanche and just love it! The only issue I HAD was how the AFM system was operating in city/suburban driving! Made the Avy ride rough while in the 4 cycle mode. Made my concerns known at the dealer - Yep, no service lights or codes. Started to drive in M5 which would disengage the AFM system. I am very pleased and happy after a 10 sec installation of the "Range" device. I have driven for a couple of weeks now and the Avy drives like Night and Day! You can't go wrong!!
