Is it just me, or is the cruise control horrible?

[Mark JT]

Really NOT impressed with the cruise control. Especially in somewhat hilly environments, the speed varies +/- as much as 5mph from set point and the tranny does a lot of hunting.
Is this normal, or does my CC need dealer adjustment?

Mine does the same. I thought that having a diesel with the torque it wouldn’t hunt as much, but it does. I usually lock it out in 6th or 7th.
The wife’s 2.0 wrangler does it as well.

2024 - 8 speed auto here. Does the same - will downshift probably one too many gears and get the RPMS up way more than needed. I just did a 6hr drive this weekend and ended up putting it in cruise control and manually shifting. Not sure there is anything else you can do?

Mine is 100% dead on. It might slow down 1 mph on a really big hill.

My 2021 JTM does the same thing, but only on hilly secondary roads. It's good on the highway, which is where I use CC the most.

I'm with @JT1 on the CC... mine stays and holds where it's supposed to. Been to Utah twice now in the past 3 years, plus all over out here on the east coast... no problems.

Mine stays pretty much dead nuts on where you set it.

My stays right where you set it. It does do a lot of gear hunting though.

Y'all must be driving gassers. My diesel doesn't but drop to 7th on the steepest highway. If I do choose I'll pull it into manual and it stays in 8th.

Yes, I am, anyway.

I can't say I've really had any issues. I'm also in Texas where it isn't too hilly though, but when I've taken it into the mountains, it's seemed fine.

You're the guy I pass, and then 5 minutes later passes me, then I pass, then 5 minutes later passes me, then I start to pass, and then he speeds up, and then I pass again...

Nope, I know how to maintain my speed LOL.

Not normal at all. Mine holds speed pretty much perfectly. I’ve only seen +/-1 mph (frequent drives through the Appalachian Mountains).

Show your dealer tech a video of it because it shouldn’t be happening. Hell I don’t think mine changed that much even when towing with cruise on.

YEP, it sucks on anything other than flat land! Applies/burns the brakes on the downhill side if you don't watch it close too.
