Model Year: 1990

Bulletin No.: 90-C-12

File in Group: 5

Number: 15

Date: Nov. '91


SUBJECT:
BRAKE SYSTEM INDICATOR LIGHT

MODELS AFFECTED:
CERTAIN 1990 RIVIERA AND REATTA MODELS


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 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 owner 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 letter which is being sent to owners, the 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, they are instructed on how to contact the National Highway Traffic Safety Administration.

CONDITION

General Motors has determined that certain 1990 Riviera and Reatta model vehicles fail to conform to Federal Motor Vehicle Safety Standards 105, "Hydraulic Brake Systems" and 101, "Controls and Displays".

These vehicles have a brake system indicator light which does not light when the ignition is in the "on" position, the parking brake applied, and the shift selector in the (P) park or (N) neutral gear range. The light functions properly in all other shift selector gear ranges.


DEALER ACTION

To correct this condition, dealers are to replace the PROM (Programmable Read Only Memory) in the BCM (Body Computer Module).
