NHTSA Complaint #10816188 — 2010 CHEVROLET TRAVERSE

ENGINE WAS RUNNING ROUGH; VEHICLE WAS SLUGGISH. CHECK ENGINE LIGHT CAME ON. DEALERSHIP, BURLINGTON CHEVROLET, RAN A DIAGNOSTIC AND THERE WERE SOME FAILED CODES (P0011 AND P008), ALL RELATED TO THE CAMSHAFT AND TIMING CHAINS. TO REPAIR, IT WOULD COST ABOUT $2,700 SINCE I WAS SIX MONTHS OVER THE POWERTRAIN WARRANTY. THEY CONTACTED GM AND THEY STATED THAT IT WOULD COST ME $681 PLUS TAX. I AGREED TO HAVE THE REPAIRS COMPLETED WHICH ALSO INCLUDED REPLACING THE WATERPUMP WHICH WAS LEAKING. I HAVE READ ONLINE THAT TIMING CHAIN PROBLEMS ON HAVE OCCURRED MORE FREQUENTLY ON 2007-2010 CHEVY TRAVERSE, SATURN OUTLOOK, GMC ACADIA, AND BUICK ENCLAVE. ALL OF THESE SUV'S HAVE THE 3.6 LITER V6 ENGINE WITH DUAL OVERHEAD CAMS. WHAT IS HAPPENING ON THESE VEHICLES IS THAT THE TIMING CHAINS ARE STRETCHING WHICH LEADS TO CORRELATION ERRORS WITH THE CAM SENSORS AND ACTUATORS. AFTER 2010, GENERAL MOTORS HAS SEEMED TO CORRECT THE PROBLEM WITH UPDATED CHAINS AND ECM CALIBRATIONS.
