      | 212 |      LEAD PLAINTIFF:       Case Filed: 2008-04-03
Case Summary:
This lawsuit alleges that General Motors Corporation (“GM”) has a secret “Engine Knock Noise Adjustment Program” that provides a free General Motors Protection Plan (“GMPP”), extended warranty, or other valuable benefits to some, but not all, owners and lessees of these Silverado models who complain about an engine knock condition in their vehicles.

Consumers describe the engine knock as “piston slap,” “piston noise,” “cold engine knock,” “rough idle,” “piston skirt slap,” “piston noise,” “cold start engine piston slap,” “cold piston slap,” “cold piston knock,” “piston slapping noise,” “tapping,” “ticking,” “slapping,” “pinging,” “rattling,” “vibrating,” “carbon in the piston,” “sounding like a diesel engine,” or “engine knock condition prevalent in Chevy trucks.” This class action lawsuit contends that GM’s policy not to tell all California owners and lessees of Silverado vehicles with engine knock that they may be eligible to receive a free GMPP, extended warranty or other valuable benefit violates California’s “secret warranty” and consumer protection laws.

Certified California Class Action

The Los Angeles County Superior Court has certified the lawsuit as a class action on behalf of the following California class:

All California owners and lessees of 1999-2003 Chevrolet Silverados equipped with 4.8L, 5.3L, 6.0L or 8.1L engines who

(1) Have an engine “knock, ping or slap” noise in their vehicles; AND

(2) Were not given notice of the condition giving rise to or the terms and conditions of GM’s Engine Knock Noise Adjustment Program.

If you live in California, own or lease one or more of these vehicles, have a knock, ping or slap noise in your engine, and did not receive prior notice of GM’s alleged Engine Knock Noise Adjustment Program, you are part of the Class, unless you exclude yourself.
