1981 PLYMOUTH RELIANT K-CAR. CONSUMER STATES ACCELERATOR PROBLEMS. *TGW THE CONSUMER STATED HIS PARENTS PURCHASED THE ABOVE MENTIONED VEHICLE. BUT, SINCE HE DID MOST OF THE DRIVING, HE ASKED THEM IF HE COULD INSTALL CRUISE CONTROL. HE THEN PURCHASED IT AND INSTALLED IT HIMSELF. THE UNIT RECEIVED ITS CONTROL PULSES FROM MAGNETS AROUND THE DRIVE SHAFT, WITH A MAGNETIC PICK UP SENSOR. AFTER ABOUT EIGHT MONTHS, THE UNIT HE INSTALLED STARTED TO ACT ERRATIC. SOMETIMES HE WOULD SET THE CRUISE SPEED, BUT WHEN HE APPROACHED TRAFFIC, HE TAPPED THE CANCEL BUTTON, THE VEHICLE WOULD CONTINUE TO SPEED UP. THERE WAS NO EFFECT WHEN APPLYING THE BRAKE PEDAL. THE CONSUMER THEN PURCHASED ANOTHER CRUISE CONTROL UNIT AND EXPERIENCED THE SAME PROBLEM.
