Dear General Motors Customer:

This notice is sent to inform you that IMPCO Automotive is conducting a voluntary emission recall that includes your vehicle.

Although IMPCO Automotive is conducting the recall, for your convenience, General Motors is assisting IMPCO by making our dealer network available to perform the recall.

Reason For This Recall: IMPCO Automotive has decided to conduct a voluntary emission recall involving certain 2013 model year Chevrolet Express and GMC Savana compressed natural gas (CNG) vehicles. These vehicles were built with an incorrect ECM calibration that, under some conditions, may cause higher tailpipe exhaust emissions than allowed by the applicable emission standards.

What Will Be Done: Your GM dealer will reprogram the electronic control module. This service will be performed for you at no charge.

What You Should Do: Please contact your GM dealer as soon as possible to arrange a service date. Instructions for making this correction have been sent to your dealer. Please ask your dealer if you wish to know how much time will be needed to schedule, process, and repair your vehicle.

If you have any questions or need any assistance, just contact your dealer or the appropriate Customer Assistance Center at the number listed below.





Emission Law Information: In order to ensure your full protection under the emission warranty made applicable to your vehicle by state and federal law, and your right to participate in future recalls, it is recommended that you have your vehicle serviced as soon as possible. Failure to do so could legally be determined to be lack of proper maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection if this recall is not accomplished.

IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS

The California Air Resources Board (CARB) requires vehicle emission recalls be completed prior to California registration renewal. Uncorrected emission recalls will result in the inability to renew your California vehicle registration.

At the time of emission recall completion, your California dealer will issue a "Proof of Correction Certificate". Keep this certificate and, if required, present it to the Department of Motor Vehicles when renewing your California registration as proof of recall completion.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
