Summary
Effective January 1, 2008 , engines built for vehicles registered in California or a CARB (Air Resources Board of California) opt-in state must be emission certified under the new California Idle Reduction Rule (CCR Title 13 Section 1956.8(a)(6)). A CARB opt-in state is any state other than California that requires CARB emission certified engines. The new ruling states that new diesel-powered vehicles with a GVWR greater than 14,000 lbs and a MY2008 or later engine that are initially registered in California must have a tamper-proof engine shutdown system (ESS) or a low NOx idle main engine unless it is a vocationally exempted vehicle.

Owners of these vehicles have filed 4 complaints in the engine category.
