Driving a 2021 Jeep Cherokee Trailhawk on the interstate with cruise control engaged. All of a sudden the vehicle decelerates/downshifts and the display screen flashes "4WD System Unavailable Service Required" and "4WD Neutral Warning". Trying to cross traffic to get to the shoulder of road and almost hit due to deceleration. Press gas pedal and nothing. Traction control light flashes on. Coast cross traffic to shoulder side of the road. Shut off Jeep. Check for loss of fluids and/or parts. Check brakes. Nothing. No smoke. No burning smell. Turn vehicle on. Vehicle automatically engages parking brake. Shift off parking brake and shift vehicle into drive and it makes a grinding noise like its trying to shift into 4WD. Snow mode pops on as well as the FWD Collision light and traction control. Jeep ran just fine until this point and no prior incidents, no bad/hard shifting. NOTHING.

On activating and setting cruise control, vehicle correctly maintains steady speed. When pressing the (+) button to increase speed, vehicle accelerates but upon removing finger the vehicle continue to accelerate until applying brakes or you disengage the cruise control function. I've been to jeep delear twice and they can't duplicate which is absurb. They said the computer control unit would have to be replaced which I will have done. I believe the technicians didn't understand what the problem was actually and just checked cruise control function. Just wanted to alert you to this malfunction.. Thank you
