Cruise Control Enables, but Can't Set

So I've read other threads where people are having the cruise randomly shutting off and either completely stop working or won't work again until the vehicle is restarted, but I think my situation is different. This is on a 2014 Laredo 4x4 with standard cruise. It was working normally on Saturday, sat for two days, and then didn't work on Monday.

The center button to enable/disable always works and the little icon shows up on the dash. However, neither of the set buttons work. Restarting the vehicle doesn't change anything. No other changes in vehicle performance. Just rolled over 30,000 miles on Saturday and it has been 7,200 miles since last oil change, which was going to happen this week anyway. Maybe it's a glitch in the computer with one of those two mileage limits? Has anyone else experienced this?

Shot in the dark here, but in troubleshooting an unrelated problem I have, fuse F82 is for the Steering Control Module and the Cruise Control. Pull the fuse for a few mins to hopefully reset it? Or maybe the fuse isn't fully seated?

Re: Cruise Control Enables, but Can't Set

Your vehicle should still be covered under the 3-Year/36,000 mile limited warranty, co I would recommend bringing this concern to your dealership's attention. Before doing so, please ensure that you are pressing the buttons firmly in their center to set the cruise.

"This condition can be induced when the steering wheel buttons on the cruise control switch are not firmly pressed in the center of the button. The SET + & RESUME buttons have 2 contacts that are required to be made to ensure proper operation for customer safety. If only 1 of the 2 required contacts is made, the cruise control will not respond and may be disabled. Only 1 contact of the switch will be made if the button is pressed near the corners of the switch or if the button is pressed very lightly."

Re: Cruise Control Enables, but Can't Set

Thanks for the replies. The buttons were definitely pressed firmly and wiggled around. However, wouldn't you know it, it started working again on the way to work this morning. Weird. I'm still keeping my 7am appt at the dealer this Friday though. Time for oil and tire rotation anyway plus any other relevant TSBs.

Re: Cruise Control Enables, but Can't Set

I am unsure if this was considered but my cruise control will not engage less than about 40kmh (25mph).

From the manual:

ELECTRONIC SPEED CONTROL — IF EQUIPPED
When engaged, the Electronic Speed Control takes over
accelerator operations at speeds greater than 20 mph
(32 km/h).


It was also discussed in this thread:

Re: Cruise Control Enables, but Can't Set

I'd be looking at the cruise control release switch on the brake pedal arm. Set too loose and it will make the CC erratic.
