NHTSA Complaint #10410030 — 2007 CHEVROLET SUBURBAN 1500

EXCESSIVE OIL CONSUMPTION - AT LEAST 1QT PER 1K MILES SOMETIMES MORE. CHEVY EVENTUALLY FIXED THIS UNDER WARRANTY AFTER PROVING OUT THE CONSUMPTION. CHEVY CORPORATE IS AWARE OF THIS PROBLEM IN THESE TRUCKS AND HAS NOT ONLY WRITTEN IT UP, BUT HAS DESIGNED A FIX FOR IT, DEALER STATES CHEVY CORP DECLINED TO ISSUE A RECALL BECAUSE IT'S A $1600 REPAIR. THE ISSUE IS TWO-FOLD. SOMETHING TO DO WITH THE VALVES NOT SEALING CORRECTLY AND OIL IN THE OIL PLAN SPLASHING UP ONTO THE CYLINDER WALLS FASTER THAN THE RINGS CAN REMOVE IT. WHEN MY VEHICLE WAS REPAIRED, THEY DID SOME WORK TO THE VALVE TRAIN, REPLACED FOULED SPARK PLUGS AND ADDED SOME TYPE OF BAFFLE TO THE OIL PAN. FIX IMPROVED POWER, FUEL CONSUMPTION AND REDUCED OIL CONSUMPTIONS TO NORMAL LEVELS. TRUCK NOW RUNS LIKE NEW. IF YOU ARE EXPERIENCING THIS GO TO CHEVY AND DEMAND THE FIX. YOU'LL NEED TO PROVE THE OIL CONSUMPTION EITHER THROUGH OIL CHANGE LOGS, OR AS I DID - WHICH WAS TO DO AN OIL CHANGE AT THE DEALER, HAVE THE OIL PLUGS SEALED BY THE DEALER, THEN DRIVE IT 6,000 MILES - HAVING THE DEALER REFILL THE OIL WHEN LOW TO TRACK CONSUMPTION. THEY WON'T WANT TO FIX THIS BECAUSE IT'S SO EXPENSIVE BUT DEMAND THE REPAIR UNDER THE WARRANTY. *TR
