Vehicle speed control
1 report
“THE CRUISE CONTROL IS VERY ABRUPTED WHEN ENGAGING THE RESUME FEATURE. THE CRUISE WILL CAUSE THE TRANSMISSION TO DOWNSHIFT AND ENGINE TO REV ABOVE 5000 RPMS FOR JUST A COUPLE OF MPH SPEED INCREASE. I BELIEVE THIS A DESIGN FLAW THAT COULD CAUSE A DRIVER TO LOSE CONTROL OF THE CAR.”
