The third icon, "Service Stop/Start System", actually refers to the unavailability of the ESS function. It's not clear how that might cross-pollinate with the other icons, which are "Service Adaptive Cruise Control" and "Cruise Control Fault".
A '24 is still too new to suspect a battery (or two) that are nearing the end of their practical service life, which in turn can cause seemingly unrelated and/or sporadic illumination of dashboard warning lights. That said, it wouldn't hurt to have the batter(ies) load tested, just to rule them out as a potentially causative factor here.

They don't turn on all the time, and when they do, they do it in sequence.
It happened the first time last week, and then Monday this week.
When I try to use Cruise Control, there's an error and says to bring it in for service.
I also notice that if I shut the engine off, and turn it back on, it seems to be OK.
I'm a big believer in making it simple stupid.
The more electronics and bells and whistles, the more for potential problems.

How are you operating the Jeep, and what are the diagnostic trouble codes, when these errors occur?

Just those Error Lights.
The Jeep still runs, but w/no Cruise Control available. It shows an error message to bring the Jeep in for servicing.
Like I said, when I shut the engine off, and restart, it appears to reset itself, w/the Error Lights disappearing and allowing for the Cruise Control to be use.
Last weekend I drove over 400 miles, mostly w/Cruise Control engaged, w/no issues.
I just had my manual transmission replaced last week due to grinding noise in it, so I wonder if the replacement process had anything to do w/these Errors.

- 2020 JTR manual
Im experiencing the same intermittent issues with cruise control activation. I too have a manual transmission. Where i live its partial rural, and partial highway driving, so I dont typically activate my cruise control unless i have a long distance of highway driving.
Lately when i push the "cruise icon" on the steering wheel, the icon (white) cruise icon will pop up on the display like normal, but when i hit the "set" button on the steering wheel, nothing happens. When the cruise control activates the "white" icon turns "green". Its acting almost like the break pedal or clutch pedal is partially depressed (and/or the sensor thinks so).
im wondering if the clutch position sensor is faulty (located under the dash above the clutch pedal). Reason i think it might be that, is sometimes when i go to start the vehicle with the clutch pedal fully depressed the vehicle will switch to run, but wont start (same as if i tried to start without the pedal depressed at all).
If i cycle through the start button again and release and depress the clutch pedal again, it will usually start. So im wondering if by the sensor being faulty it
(1) thinks the clutch pedal is slightly depressed when im driving and wont activate the cruise control
(2) thinks i dont have the clutch pedal fully depressed when im trying to start. Is your experience the same?
have you replaced anything since your last post?

Any updates on what is? My 2025 with a manual has the same issue. Dealership is booking 2 weeks out and would love to know what your issues ended up being.
