Chevrolets, GMCs with Defective Gen IV Vortec Engine Alabama Complaint

October 8, 2021

General Motors, LLC offered the Generation IV 5.3 Liter V8 Vortec 5300 LC9 engine as an option in certain 2011-2014 model year Chevrolet and GMC vehicles. This class action alleges that the engine was defective and “engineered to fail.” The engine consumers far too much oil, the complaint alleges, a condition that results in “low oil levels, insufficient lubricity levels, and corresponding internal engine component damage.”
