<P> GM ceased production of the 4.6 L Northstar in 2003 , and the remaining series in July 2010 . The final cars to receive it , the Cadillac DTS , Buick Lucerne , and Cadillac STS , rolled off the line in 2011 . It was replaced by the GM LS small - block OHV engine , used in newer Cadillac V8 models like the CTS - V , marking a step back to a simpler , more reliable push rod engine design . </P>
