CAMPAIGN: RIGHT FRONT BRAKE PIPE INTERFERENCE. Buick Regal 1997

NOTE: GM OF CANADA CAMPAIGN 97065 IS LOCATED BELOW THE U.S. VERSION

PRODUCT SAFETY CAMPAIGN

SUBJECT: 97065 - RIGHT FRONT BRAKE PIPE INTERFERENCE

MODELS: 1997 BUICK REGAL GS

The Highway Safety Act, as amended, provides that each vehicle which 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 (60) 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 entitied 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 to provide 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. As you will see in reading the attached copy of the divisional letter that is being sent to customers, the customers are being instructed to contact the Buick Customer Relations Center if their dealer does not remedy the condition within five (5) days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.

DEFECT INVOLVED

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1997 Buick Regal GS model vehicles. The right front brake pipe on some of these vehicles may be contacting the power steering pressure hose/pipe assembly. This condition can cause the brake line to wear through resulting in a loss of brake fluid.

If this condition were to occur in a situation where stopping distances were minimal, a vehicle crash could result without prior warning. Also, if brake fluid were to contact hot engine components an engine fire could occur.

To prevent the possibility of this condition occurring, dealers are to inspect for proper clearance between the brake line and power steering pressure hose/pipe assembly. Assemblies found to be out of position will be repositioned and all assemblies will be secured to maintain proper clearances. Additionally, those brake lines found to have been damaged will be replaced and properly routed.

VEHICLES INVOLVED

Involved are certain 1997 Buick Regal GS model vehicles built within the following VIN breakpoints:

PLANT YEAR MODEL PLANT CODE FROM THROUGH 1997 Regal GS Oshawa #2 '1' V1400018 V1452341

NOTICE: 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.

PARTS INFORMATION

It is anticipated that approximately less than 5% of the suspect brake pipes will require replacement for this condition. Therefore, please do not order parts for shelf stock. Only order parts when truly needed.

Parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your 'Involved Vehicles Listing" prior to ordering requirements. Normal orders should be placed on a DRO = Daily Replenishment Order. An emergency requirement should be ordered on a CSO = Customer Special Order.

CUSTOMER NOTIFICATION

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

COURTESY TRANSPORTATION

When inspection indicates that a brake pipe replacement will be required, dealers may wish to review Corporate Bulletin 68-05-02a released in October 1996 for guidelines regarding loaner/rentals.

The availability of courtesy transportation to customers whose vehicles are involved in this campaign is of the utmost importance in maintaining customer satisfaction. Dealers are to take the steps necessary to ensure that these customers clearly understand that courtesy transportation is available and will be provided upon request at no charge. Dealers should submit such claims in the normal manner and appropriate credit will be issued.

DEALER CAMPAIGN RESPONSIBILITY

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 appropriate divisional 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.
