Date:
November 1990
Section:
5, 9B
Subject:
BRAKE STOPLAMP SWITCH
Models/Years:
CERTAIN 1989 AND 1990
OLDSMOBILE CUTLASS SUPREME MODEL VEHICLES
CONDITION
General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1989 and 1990 Oldsmobile Cutlass Supreme model
vehicles. These vehicles may have a faulty brake stoplamp switch, which could result in the stoplamps not illuminating on application of the brakes. If
this should occur in situations where a driver in a trailing vehicle is otherwise unable to recognize a braking action in sufficient time to respond
appropriately, a vehicle crash could occur without prior warning. In some cases, failure of the stoplamp switch can result in the stoplamps staying on at
all times.
In addition, in vehicles equipped with cruise control, a faulty stoplamp switch can result in resumption of the cruise control function upon release of the
brake pedal. If this occurs, the cruise control feature can be disengaged by moving the cruise control switch to the "OFF" position, or by reapplying the
brake. Once the vehicle speed drops below 12 - 14 MPH, the cruise feature will be automatically disengaged. On vehicles equipped with manual
transmissions, depressing and releasing the clutch pedal will also disengage the cruise control feature.
