Buick Regal: Electrical
Affects Buick Regal · 1988 — about 555 vehicles.
The hazard
A LOOSE ELECTRICAL CONTACT ON THE ROTARY STOP LAMP SWITCH CAN OVERHEAT AND MELT THE SURROUNDING PLASTIC CAUSING THE CONTACT TO STICK OPEN. THIS WOULD RESULT IN INOPERATIVE BRAKE LIGHTS WHEN THE BRAKE PEDAL IS DEPRESSED. ALSO, THE TRANSMISSION CLUTCH CONTROL AND CRUISE CONTROL WOULD REMAIN ENGAGED RESULTING IN A "CRUISE RESUME" CONDITION WHEN THE BRAKE PEDAL IS RELEASED AT SPEEDS ABOVE 12 MPH WITH THE CRUISE CONTROL SWITCH "ON" AND TCC ENGAGEMENT UNTIL NORMAL DROP OUT SPEED. UNEXPECTED "CRUISE RESUME" OR INOPERATIVE BRAKE LIGHTS COULD RESULT IN A VEHICLE CRASH WITHOUT PRIOR WARNING. CORRECTION: ROTARY STOP LAMP SWITCH WILL BE REPLACED ON AFFECTED VEHICLES.
