NHTSA Complaint #11205246 — 2008 GMC SIERRA 1500

MY SIERRA DEVELOPED A NOISE ON DECELERATION. TOOK IT TO THE GMC DEALER AND WAS TOLD IT HAD A WORN CAM. $5500 TO REPAIR, $7750 TO REPLACE ENGINE. I KNEW THAT A WORN CAM WOULD CAUSE LIFTER NOISE ALL THE TIME SO THAT WAS WRONG INFO. UPON FURTHER INVESTIGATION I FOUND OUT THIS TRUCK HAS ACTIVE FUEL MANAGEMENT. WHAT HAPPENED WAS A FAILURE OF THE SYSTEM. IT SHOULD BE NOTED THAT THIS TRUCK ALWAYS HAD HIGH OIL CONSUMPTION. I DEACTIVATED THE ACTIVE FUEL MANAGEMENT SYSTEM. THE TRUCK RUNS ON ALL 8 CYLINDERS, IS COMPLETELY QUIET AND NO LONGER USES OIL. IT IS BETTER THAN NEW. I ALSO FOUND HUNDREDS OF COMPLAINTS SIMILAR TO MY AND PAID FOR EXPENSIVE REPAIRS. THIS ACTIVE FUEL MANAGEMENT IS NOTHING MORE THAN A SCAM TO FALSELY INCREASE FUEL MILEAGE AND TO RIP OFF CUSTOMERS WHEN IT GOES BAD. IT CAN BE DEACTIVATED WITH A $175 CHIP.
