Cruise control problems

[S.D.W.]

My cruise will shut off when going down the road and will give me a code saying disable services required, but resets itself when you turn the truck off has anyone else having this problem???

I've only had it happen a couple times, when someone cut in front of me and set off the FCW.

Probably going to have to take it in to the dealership.

I've had that issue as well. It seems much worse in very wet/damp conditions (South Carolina), but better in dry cold (Minnesota.) Sometimes I can get it to re-engage quickly, without restarting the engine. Wondering if it's a bad sensor or wiring?

I have FCW w/auto braking disabled. I'm going to try and get it into the dealership in the next week or so: I'll update the forum with what I find out.

I haven't had the issue but I think the cruise control SUCKS.

The JT seems to have no ability to "read" the road ahead and lay off or increase the speed----and maybe no vehicle does this. I just know that EVERY other brand vehicle I've driven that had a cruise control it was MUCH smoother and responsive [1960's GM and MB, 70's-today of almost all US and foreign manufacturers].

These are good points. OP, do you have adaptive cruise with forward collision warning? That will drastically change the situation.

It's not a Tesla. It doesn't 'read' the road or monitor the painted lines. If you have the ACC, then it will monitor the traffic in your lane and adjust the speed as needed to maintain the set distance between you. I do find the ACC to be a bit aggressive when the lane clears and it resumes speed.

Hey Bill, thanks for the reply. I do have the advanced and regular cruise control. I like the ACC when on the highway and I'm at a steady cruise on flat terrain. But any hills and the damn thing is literally slamming on the brakes instead of just letting off the gas even when there is no one in front of me. Had a guy follow me to confirm my brakes came on multiple times.

I've noticed that also. After I got the brake controller installed, I saw that it was also using the brakes to control speed, especially when going downhill.

Am I the only person who has had multiple Jeeps with ACC, FCW and so on, where all features worked just fine?
Nothing aggressive about any of it. Cruise really keeps speed extremely close - closer to anything else I've had. I'd say within +/- 1 mph.
ACC works great as well. It's perfect for the traffic on I80 here with the hills and TRUCKS.
If I'm behind a truck that has really slowed down on a hill and the other trucks FINALLY stop playing games and move over so I can move left to get around the slow one, it does at times kick down a couple of gears to get up to speed again- but nothing I'd say is bad at all.
In fact, use regular cruise on a Chevy or Ford car or truck, have it set at 65, come to a stop, then take off and when you hit 35 mph hit resume on the cruise, it's going to kick down and nail it to get to the set speed again. So in many ways, the Jeep ACC is not at all different than ordinary cruise control in other vehicles I've owned. Hit resume after a stop and it thinks you mean "ASAP".
ACC just follows the model of cruise from the last 40 years, IMO.
Try it some time. Have cruise set up to 65 or so, come to a stop, get to the point the cruise will take over again (often above 30 or so mph, and then hit resume.
Does it get back up to speed as if your grandmother was driving, or like your teenage son?

My ACC rarely uses brakes unless I'm coming up on someone fast - then it mostly just lets off.
Some of how this operates may be dependent on how you have the "distance" set on ACC.

My ACC works a treat... one of the many things I love about this truck.
It can get a bit confused on rare occasions... construction zones, etcetera, and this just reminds me that the machines are not all that close to taking over driving from us meat bags.

Have owned both a Tacoma and Honda Ridgeline with ACC, they both did the same thing of aggressively kicking down a gear to speed up once the slower vehicle in front moved out of the way.

I hadn't thought about the acc distance setting, I'll take a look at that.

Always been proud of the fact I actually understand how cruise control works. Use the cancel and resume functions all the time. Most don't seem to understand that when cruising each set+ feature increases the speed in 1 MPH increments and vice versa with the set-.

On my Camaro Z28 with the 6 speed manual anytime the clutch went in the cruise disabled just as if you tapped the brakes.

I'm big on downshifting to have the engine assist in slowing down---quite the shock on my 6 speed Mojave that downshifting while on cruise just resulted in the cruise control quickly accelerating back up to the set speed. Same same on upshifts, changing gears doesn't effect the speed control at all. So now I hit cancel and then start downshifting and I don't worry about shifting to 5th and 6th from 4th when the hills are behind me and I'm on flat ground.

Other than being a little aggressive, the ACC works quite well and I use it all the time. I keep the following distance at maximum, but it seems to ignore that and use the minimum when in stop and go traffic. I like being able to hit resume from a stop and have it take over without having to reset and adjust the speed again.

Guess I'm glad I have the old fashioned cruise control.
