One problem related to vehicle speed control has been reported for the 1999 Dodge Grand Caravan. The most recently reported issues are listed below.
Everytime I am going downhill or steep roads, I have no control of my cars deceleration except by using my brakes. I have no manual override for downshifting or engine braking. This causes my brakes to overheat and fade. My car is equipped with an autostick (manual electronic shift), which the controls for are on the shifter handle on the column. The wire inside the shifter handle loses its connection or gets cut at the pivot point, making it non-operational. I've called my local dealer for the parts needed (autostick shifter lever) and they said, that part has been on backorder nationwide. I've also went online and talked to a few owners of the same type vehicle and they had exactly the same safety issue. There is no way to fix the cut wire because the shifter handle is a sealed unit.
