i have 2013 cascadia isx2250. yesterday i was driving normally like every day.suddenly cruise kick in by it self and start increasing my speed without touching it . i try to turn it off it won't it stuck on, i push clutch to deactivated it won't the icon still appear on the dashboard., the only way i can turn it off is to push the brake pedal and turn it off manually but after 10 seconds it kicks back on again and keep increasing speed. i notice also that when the cruise kick in the engine brake is not working i try to turn it on by pressing the switch but it 's not responding at all.
i did also try to turn the power off from the batteries and turn it back on see if it help but no luck still same problem.
i drove like that for 100 miles to make it truck stop. just 2 miles before truck stop exit i succeed to turn it off manually and also the engine brake switch is working normally
any one face this before please help thx alot

medseg2003, I'm not sure how the Cascadia works with a Cummins but I recently had an issue sounding eerily similar. Cruise control was turned on, by me, but didn't work. Nor did the Jakes. My issue turned out to be the clutch switch. About a $100 job at Freightliner, or if you can fit your hand up inside that area the part is $63.00. My wrist is bad these days from beating Cryo fittings on and off three or four times per day for the past 20 years so I had Petro in Dodge City do mine. If you do go to the dealer remember they love those "diagnostic" charges.
