NHTSA Complaint #10864069 — 2008 CHEVROLET AVALANCHE 1500

EXCESSIVE OIL CONSUMPTION. IT THE 5.3L WITH ACTIVE FUEL MANAGEMENT SYSTEM. GM KNOWNS THERE IS A PROBLEM AND THE ONLY FIX IS TO REPLACE THE RINGS AND PISTONS OR REPLACE THE ENTIRE ENGINE AT THE OWNERS EXPENSE, 5,000.00 - 8,000.00. SINCE IT'S IT'S A DESIGN FLAW, I FEEL THEY SHOULD FIX IT AT NO COST. IT CONSUMES OVER QUART AND A HALF PER 1000 MILES, BOTH HIGHWAY AND CITY AND AT TIMES 2 QUARTS WITH PULLING HEAVY LOADS. I HAVE DONE A OIL CONSUMPTION TEST WITH THE DEALER AND THEY HAVE ADMITTED IT GOES THROUGH A LOT OF OIL. I BOUGHT THE TRUCK USED, AND THE DEALER WHO SOLD IT TO ME NEVER MENTIONED THIS TRUCK COULD HAVE THIS PROBLEM.
