FMVSS Noncompliance - Power Brake Booster Vacuum Supply Hose Kinked

General Motors has decided that certain 2000 Chevrolet and GMC 1/2 ton C/K utilities and Suburbans equipped with vacuum power, four-wheel-disc brakes (RPO JC5) and built at Janesville Assembly Plant, may fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) 105, "Hydraulic Service Brake -- Normal, Emergency, and Park Braking Performance" or Canada Motor Vehicle Safety Standard (CMVSS) 105, "Hydraulic and Electrical Brake Systems." These vehicles may have been built with a kinked brake booster vacuum supply hose. A vehicle with a sufficiently kinked brake vacuum hose does not comply with certain stopping distance requirements related to multiple brake applications of F/CMVSS 105. If a vehicle required minimal stopping distance under these brake application conditions, a vehicle crash could occur.

Dealers are to reroute the brake booster vacuum supply hose.

Involved are certain 2000 Chevrolet and GMC 1/2 ton C/K utilities and Suburbans equipped with vacuum power, four-wheel-disc brakes (RPO JC5), built at Janesville Assembly Plant, and built within these VIN breakpoints:

Important: Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada only) or DCS Screen 445 (IPC only) before 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 Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign.

No parts are required for this campaign.

1. Disconnect the brake booster vacuum hose (1) from the brake booster.
2. Reroute the brake booster vacuum hose rearward of the engine and behind all other hoses and wiring harnesses.
3. Connect the brake booster vacuum hose to the brake booster.
4. Install the GM Campaign Identification Label.

FOR US AND CANADA

Customers will be notified of this campaign on their vehicles by General Motors (see copy of customer letter included with this bulletin).

FOR IPC

Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached suggested dealer letter.

FOR US AND IPC (US States, Territories, and Possessions)

The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall campaign notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the campaign is not completed within a reasonable time.

This bulletin is notice to you that the new motor vehicles included in this campaign may not comply with the standard identified above. Under Title 49, Section 30112 of the United States Code, it is illegal for a dealer to sell a new motor vehicle which the dealer knows does not comply with an applicable Federal Motor Vehicle Safety Standard. As a consequence, if you sell any of these motor vehicles without first performing the campaign correction, your dealership may be subject to a civil penalty for each such sale.

ALL

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.
