CAMPAIGN: ANTI-LOCK BRAKE HYDRAULIC UNIT MOUNTING BOLTS. Buick Reatta 1989

For 1990-2009 cars

# CAMPAIGN: ANTI-LOCK BRAKE HYDRAULIC UNIT MOUNTING BOLTS

#### MODELS AFFECTED: 1989 RIVIERAS WITH ANTI-LOCK BRAKE SYSTEM (JL9)

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 owner has tendered it for repair. A failure to adequately 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 owners 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 owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the owner letter, owners 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, owners are instructed how to contact the National Highway Traffic Safety Administration.

#### CONDITION

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1989 Buick Riviera models equipped with Anti-Lock Brake System (ABS). Involved vehicles may have one or both ABS hydraulic unit mounting bolts not properly seated. This condition could cause increased brake pedal travel and/or poor pedal feel if the attachment loosens. In addition, with time, this condition could lead to separation of the ABS hydraulic unit from its mounting bracket. Separation would result in loss of brake function and could result in a vehicle crash without prior warning.

#### DEALER ACTION

To correct this condition, dealers are to replace the hydraulic unit mounting bolts on all vehicles involved according to the instructions in the Technical Procedure section of this bulletin.

#### VEHICLES INVOLVED

All 1989 Riviera model vehicles equipped with Anti-Lock Brake System (option code JL9), within the following vehicle breakpoints (Buick records indicate that a total of 125 vehicles are affected):

#### DEALER CAMPAIGN RESPONSIBILITY

Dealers are to service all vehicles involved in this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership. Whenever a vehicle subject to this campaign is taken into your new or used car inventory, dealers are to take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.

Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the dealer and arrangements made to make the required modification according to instructions contained in this bulletin.

#### DEALER MATERIAL

If your dealership has vehicles involved in this campaign, you will receive the following items:

- Listing of all vehicles involved in this campaign shipped to your dealership.

- One (1) Campaign Identification Label per vehicle involved.

Involved vehicles have been identified by Vehicle Identification Number computer listings. Computer listings contain the complete vehicle identification number, owner name and address data, and are furnished to the involved dealers with the campaign bulletin. Owner name and address data will enable dealers to follow-up with owners involved in this campaign.

These computer listings may contain owner 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.

Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

#### OWNER NOTIFICATION

Owners of vehicles involved in this campaign will be notified by Buick Motor Division (see copy of owner letter included with this bulletin).

#### CHANGE OF OWNER INFORMATION

Dealer are to use the Dealer Communication System (DCS) to provide Buick Motor Division with subsequent Buick owner information. By reporting a change of owner name or address of a vehicle in campaign status over the DCS, the need to send a CVAR for that vehicle is eliminated. Terminal input instructions are covered in the DCS Manual under Section 9, Page 9-JOlA and B.

In addition, with time, this condition could lead to separation of the brake hydraulic unit from its mounting bracket. Separation would result in loss of brake function and could result in a vehicle crash without prior warning.

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.
