CAMPAIGN: CRUISE CONTROL CABLE SEPARATION
SUBJECT: CRUISE CONTROL CABLE SEPARATION
MODELS: Certain 1994 Oldsmobile Ciera and Buick Century
TO: ALL GENERAL MOTORS DEALERS
General Motors of Canada Limited has determined that a defect which relates to motor safety exists in certain 1994 Oldsmobile Ciera and Buick Century model vehicles equipped with cruise control and 3.1 liter engines (engine code 'M'). These vehicles exhibit a condition in which the cruise control cable conduit may separate from the conduit end fitting. In this event, engine speed may not decrease to a level anticipated by the operator. Although the vehicle can still be stopped with the service brake, loss of accelerator control could result in a vehicle crash without prior warning.
To prevent the possibility of this condition occurring, dealers are to install a replacement cruise control cable.

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.
