Cruise control cable failed causing the vehicle to run at high speeds without pressing the accelerator making the vehicle dangerous to drive during wet weather. nlm

Cruise control cable unlatches from cruise control module jamming accelerator cable to full throttle. we picked up new car, and were driving at 35 mph when the car lurched ahead at full throttle. stepping on brakes did not stop vehicle. ignition had to be shut off. tow called. taken to dealership where problem was identified to service mgr. they said they would correct problem by taking parts from another new car. they jury-rigged defect with plastic wireties. the problem occured again the next day but ties held cable from jamming. we are worried that these plastic ties do not solve, but mask problem and will not last. we would like the prevelence of this problem checked. we would also like to be contacted by gm/buick re problem and the dealer's "solution". *ak
