Recall history
1 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
97V131000 · Vehicle Speed Control
Reported: 1997-08-19 (August 19, 1997)
THE CRUISE CONTROL AND THROTTLE CABLES ARE ATTACHED TO THE SAME THROTTLE VALVE ACTUATING LEVER AT THE THROTTLE HOUSING. IT IS POSSIBLE THAT THE PLASTIC BUSHING ON EITHER CABLE COULD BREAK DUE TO ENVIRONMENTAL INFLUENCES COUPLED WITH VIBRATION. IF THE BUSHING BREAKS, THE OUTER CABLE HOUSING CAN SEPARATE FROM THE BUSHING. IN THIS CASE, DURING APPLICATION OF THE THROTTLE PEDAL WITHOUT CRUISE CONTROL BEING ENGAGED, THE OUTER TUBE COULD CATCH ON THE EDGE OF THE BROKEN BUSHING.
Consequence: THIS COULD CAUSE THE THROTTLE VALVE TO REMAIN PARTIALLY OPEN. IT HIS WERE TO OCCUR, THE CAR MIGHT NOT DECELERATE AS EXPECTED INCREASING THE RISK OF A VEHICLE CRASH.
Remedy: DEALERS WILL INSTALL A SPRING STEEL CLIP ON THE OUTER TUBE OF EACH CABLE IN THE AREA OF THE ADJUSTING SCREW AND PLASTIC BUSHING. THE CLIP IS DESIGNED TO PREVENT THE OUTER TUBE FROM DISLODGING FROM THE BUSHING.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
1996: 0 complaints · 1997: 0 complaints
