Cohen Milstein was one of the principal counsel in a series of class action lawsuits filed across the country alleging that General Motors sold cars during 1996-2003 that contained a defective engine coolant.  The cases alleged that Dex-Cool caused engine parts to corrode and gum up with a mud-like substance, resulting in engine overheating and failures of certain parts and systems.  Classes were certified in Missouri and California and the cases were settled before trial with GM, making cash payment to up to $400 or $800 for covered repairs.
