I have just found with my new Sahara that when Radar cruise control is ON (and no car ahead to affect the speed) that if you accelerate using the accelerator pedal and then press SET the speed reverts to the original setting (less 1 kph). Dealer was unsure whether this is a fault or intended. If intended it's dangerous! On a freeway I accelerated from 80 kph to 110 kph and when I pressed SET (to hold the speed at 110 kph, or so I thought) the brakes came on as the car attempted to go back to 79 kph. Gave the bloke behind a bit of a surprise too! Anyone else had this issue? On normal cruise control it all works as you would expect.
