CAMPAIGN: ACCELERATOR PEDAL ASSEMBLY. Buick Roadmaster 1994

For 1990-2009 cars

# CAMPAIGN: ACCELERATOR PEDAL ASSEMBLY

#### SUBJECT: ACCELERATOR PEDAL ASSEMBLY

#### MODELS AFFECTED: CERTAIN 1994-1995 BUICK ROADMASTERS

The National Traffic and Motor Vehicle 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 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 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 to provide these burdensome solutions, 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 letter that is being sent to customers, the customers are being instructed to contact the Buick Customer Assistance 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 certain 1994/1995 Buick Roadmaster cars may have been built with a defective accelerator pedal assembly which causes the vehicles to fail to conform to the requirements of the Federal Motor Vehicle Safety Standard 124, "Accelerator Control Systems." Under some circumstances at low temperatures, there may be excessive friction in the accelerator pedal assembly. If there is excessive friction in the pedal assembly, in the event of a failure of the throttle return spring, the engine speed may not return to idle as specified in FMVSS124.

To correct this condition, it will be necessary to replace the accelerator pedal assembly.

#### VEHICLES INVOLVED

Involved are CERTAIN 1994/1995 Buick Roadmasters built with the following VIN breakpoints: Plant Year Model Plant Code From Through -------------------------------------------------------------- 1994 B Arlington R RR427594 RR439029

1995 B Arlington R SR400001 SR411603

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, customer name and address data, and are furnished to involved dealers with the campaign bulletin. Customer name and address data furnished will enable dealers to follow-up with customers involved in this campaign.

These listings may contain customer names and addresses obtained from State Motor 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. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

#### PARTS INFORMATION

A preshipment of parts will be sent to involved dealers the week of June 5, 1995. Preshipment will equal parts for 50% of the number of vehicles to be repaired. Preshipment parts will be charged to the dealers' open parts account.

Additional parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO). To ensure these parts will be obtained as soon as possible, they should be ordered from GMSPO on a "CIO" order with no special instruction code, but on an advise code (2). All Goodwrench Parts System test dealers should order on a "V.I.P." order.

Customers of vehicles recently sold from your new vehicle inventory with no customer information indicated on the dealer listing, are to be contacted by the dealer, and arrangements made to make the required correction according to the instructions contained in this bulletin.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
