SUBJECT:
ANTI-LOCK 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
