Open the full vehicle complaint log (all categories)I HAVE AN 2010 BUICK LACROSSE CXL I'VE HAD FOR 8YEARS WITHIN THOSE YEARS I'VE REPLACED THE CATALYTIC CONVERTER 2X WHICH IS PRETTY PRICEY CONSIDERING THEIRS 3PARTS. THIS RECENT TIME IT WAS REPLACED THERE WAS GAS IN THE OIL. MY MECHANIC STATES IT BECAUSE OF THE HIGH PRESSURE FUEL PUMP. WHICH I FEEL SHOULD BE REPLACED BY BUICK THERE'S NO WAY I SHOULD BE CHANGING A CONVERTER THIS OFTEN.
