Subject: | Light and Medium Duty Truck Warranty and Crossline Warranty Eligibility and Guidelines for Chevrolet and GMC Dealers

Models: | 2007 and Prior Chevrolet, GMC and Isuzu Light and Medium Duty Trucks

This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 02-00-89-007 (Section 00 -- General Information).

Important: This service bulletin is not applicable to 'GM of Canada' dealers. 'GM of Canada' dealers should refer to the most current Home Office Letter regarding crossline warranty policies.

The purpose of this bulletin is to clarify vehicle warranty eligibility and guidelines for all light and medium duty trucks, including the new GMC TopKick and Chevrolet Kodiak trucks (C4500-8500).

If the dealer is eligible to provide crossline warranty, one of the following guidelines must apply:

• | The customer requires EMERGENCY warranty service.

• | The vehicle was sold used by the servicing dealer, regardless of the dealer's new vehicle franchise.

• | Any commercial light duty truck may obtain warranty service at either a Chevrolet or GMC light duty commercial dealer.

• | Any medium duty truck may obtain warranty service at either a Chevrolet or GMC medium duty dealer.

Crossline warranty can be provided between Chevrolet and GMC dealers who have the appropriate light and/or medium duty franchise.

Light duty only dealers cannot perform crossline warranty on medium duty vehicles except for the C3500 HD and new C4500 series. Warranty repairs cannot be performed on any other medium duty products.

Likewise, medium duty only dealers cannot perform light duty crossline warranty except for the C3500 HD and C4500 series.

Warranty repairs can only be performed on W or T series trucks at medium duty dealers with that series franchise. Crossline warranty on W or T series trucks is only allowed between Chevrolet and GMC medium duty dealers with that series franchise.

Important: The primary crossline rule for both Chevrolet and GMC light and medium duty dealers is that they can only provide warranty repairs on the platforms they sell.

The following summarizes the crossline warranty eligibility on GMC and Chevrolet truck dealers by product.
