My fuel pump started to go,whining really loud,time to replace...according to Haynes manual,in trunk there's access panel to get to it,so called cadillac dealership,they confirmed...took apart the trunk,no panel...called Advanced Auto Parts,same thing,access panel in trunk...even took out back seat...no access panel...so now I have to drop out the exhaust and the tank!!! This is BS...most expensive cars,almost, you think they would be made properly like stated and everyone even mechanics at dealership said it should be there!!!
