Cold Temperature No Start

General Motors has decided to conduct a Voluntary Emission Campaign involving certain 1999 Chevrolet Tracker model vehicles equipped with 2.0 L engines (RPO L34 and VIN Code 'C'). These vehicles may exhibit a no-start condition in cold weather (5°F or colder).

To correct this condition, dealers are to replace the powertrain control module (PCM). If the owner has experienced a no-start condition, the spark plugs will also be replaced.

Involved are certain 1999 Chevrolet Tracker model vehicles equipped with 2.0 L engine (RPO L34 and VIN Code 'C') and built within the following VIN breakpoints:

Important: Dealers should confirm vehicle eligibility through VISS (Vehicle Information Service System) prior to beginning campaign repairs. [Not all vehicles within the above breakpoints may be involved].

Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the campaign bulletin. The customer name and address data furnished will enable dealers to follow-up with customers involved in this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

These dealer listings may contain customer names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign.

Important: An initial supply of powertrain control modules (PCMs) equivalent to 50% of involved vehicles, will be pre-shipped to involved dealers of record. This pre-shipment will occur the week of February 15, 1999. Pre-shipped parts will be charged to dealer's open parts account.

Additional parts required for this campaign are to be obtained from General Motors Service Parts Operations (GMSPO).

Please refer to your "involved vehicles listing" prior to ordering parts. Most dealers do not have vehicles involved in this campaign; if you do not have any involved vehicles, please do not order parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered as CSO = Customer Special Order.

Important: Due to the small number of vehicles involved and due to limited initial parts availability of powertrain control modules (PCMs), dealers are requested to limit initial parts ordering to parts required for vehicles which are sold and pending delivery. Most dealers do not have vehicles involved in this campaign; if you do not have any involved vehicles, please do not order parts.

Customers will be notified of this campaign on their vehicles by General Motors (see copy of typical customer letter included with this bulletin - actual divisional letter may vary slightly).

In order to ensure full protection under the emission warranty, and the right to participate in future recalls, the customer notification letter recommends that customers have their vehicles serviced as soon as possible. It also advises that failure to do so could legally be determined to be lack of proper maintenance. The vehicle may fail a state or local emission inspection test if the recall work is not completed.

All unsold new vehicles in dealers' possession and subject to this campaign MUST be held and inspected/repaired per the service procedure of this campaign bulletin BEFORE customers take possession of these vehicles.

Dealers are to service all vehicles subject to this campaign at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such customers a copy of the customer letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.

When a California emissions campaign is completed by a GM dealer, the dealer must provide the vehicle owner a "Proof Of Correction Certificate" which the owner may need to present to the California Department Of Motor Vehicles (DMV) when renewing their vehicle registration. Without this correction certificate, the owner may be unable to renew their vehicle registration.

Additional Certificates can be obtained, at no charge, from Dealer Support Materials by calling 1-888-414-6322, (Monday-Friday, 8:00 a.m. to 5:00 p.m. EST). Ask for GM Item Number 1825 when ordering.

This information may be inserted with a typewriter or a ball point pen.

Dear Chevrolet Customer:

This notice is sent to inform you that General Motors is conducting a voluntary emission recall campaign that includes your vehicle.

General Motors has decided to conduct a Voluntary Emission Campaign involving certain 1999 Chevrolet Tracker model vehicles equipped with 2.0 L engines. These vehicles may exhibit a no start condition in cold weather conditions (5°F or colder).

To correct this condition, your dealer will replace the powertrain control module (PCM). If you have experienced a no-start condition with your Tracker, the spark plugs will also be replaced. This service will be performed for you at no charge .

Please contact your Chevrolet dealer as soon as possible to arrange a service date and to assure parts availability. 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.

Should your dealer be unable to schedule a service date within a reasonable time, you should contact the Chevrolet Customer Assistance Center at 1-800-222-1020. Deaf, hearing impaired or speech impaired please call 1-800-833-2438 (Utilizes Telecommunication Devices for the Deaf/Text Telephones TDD/TTY).

The enclosed customer reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction in the shortest possible time. If you no longer own this vehicle, please let us know by completing the postage paid reply card and returning it to us.

Your dealer may provide you with shuttle service or some other form of courtesy transportation, if required, while your vehicle is at the dealership for this repair. Please refer to your Owner's Manual and your dealer for details on Courtesy Transportation.

In order to ensure your full protection under the emission warranty made applicable to your Chevrolet Tracker vehicle by State or 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.

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

At the time of emission campaign 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 campaign 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.
