GM Silverado “Piston Slap” Secret Warranty Lawsuit

Elizabeth Pritzker, as Class Counsel, represented a certified class of owners and lessees of Chevrolet Silverado trucks whose vehicle engines had abnormal “knock, ping or slap” noises.  The complaint alleged that GM maintained an Engine Knock Noise Adjustment Program that gave owners and lessees who complained about the problem free extended warranties, GM Protection Plans and other benefits, but that GM failed to notify all affected owners and lessees of the Adjustment Program and its benefits.  A court-approved class settlement ultimately was ratified by the Bankruptcy Court for the Southern District of New York after GM filed for bankruptcy protection, and cash payments obtained in the original settlement were paid out to class members in January 2013.
