Cruise control ???
 
Has anyone had any issues with their cruise?

Curious if anyone else has experienced this.
Occasionally when driving freeway speeds my cruise will cut out. Seems to happen more while
Going up hill or cornering.

2013 jkur.

2013 JKUR also. Never had an issue. Possible flash update needed maybe?

Is this happening on a long steep grade? I have had a couple of cars that would suddenly cut the cruise if it has been giving at/near full throttle for more than 30 seconds or so. I think it is a fail-safe mechanism, like the engineers think if the cruise has given high throttle for awhile something must be wrong.

I haven't had a chance to get my Jeep onto I-70 west of Denver yet, but a couple of my cars will cut the cruise there. Annoying as hell, and dangerous, IMHO.

I've had cars do that too. If the hill was very steep, and the engine was working at or near full throttle for an extended period of time ~30 seconds or so, cruise control would disengage. I found locking the car out of OD would help stop this many times.

Mine has cut off after hitting a decent sized bump on the highway, I figured its designed to do that if you have an accident

Yes. I also think is Is very dangerous. It causes the jeep to "jump" (May be the wrong word...) but scares the hell out of my wife.

The fact that the cruise is cutting out while cornering makes me wonder if it's a short in the steering wheel.
Looks as though you have lots of warranty left to get to the bottom of this. I would be curious to know what the dealership says.

I have the 6 speed.

Thanks for the responses. I have not driven the jeep in a long time an keep forgetting to ask about it.

Try taking that hill in 5th gear with the CC on and see what happens.

yes
 
i have a '13 JKUR, 6spd man, and my cruise will drop on uphills occasionally. Kinda frustrating. Happens in different gears too. I assume it is caused by the cruise needing more throttle than the computer wants to allow, but I do plan to ask my dealer about it the next time I'm in there.

Im definitely curious about the actual cause/cure if anyone has had this diagnosed and corrected.

I believe that steering wheel angle vs lateral acceleration is monitored by the ESP system and can cause the CC to disengage. And I wouldnt be surprised if there are other items being monitored that could have the same affect.

Cruise control working intermittently
 
2012 Rubicon Unlimited

i have previously had codes P0591 and P0579 come up. I cleared them and the codes have not came back. Just prior to the codes coming up and now afterward, cruise will not turn on immediately. I have to press the on button numerous times until it finally turns on. Once it turns on, it will work fine.

Any ideas as to where to start checking on this?

thanks

I have a '14 JKU with auto, and I've driven some pretty hilly stuff with the cruise engaged and haven't had it shut off on me.

blueguy 05-29-2015 03:44 PM

The only time my 12 manual cuts off for me is when one one curve on I5 that has a bump. Cuts out then you can turn it back on jest fine, I think it's if you have a accident.

If the Electonic Stability Control (ESC) kicks in, it will cut the cruise off. You'll notice this in the wintertime if you drive over an icy spot with the cruise on, and a tire breaks loose. It's a safety thing.

Mine would cut out at one spot on a local highway when going over a hump in the road. I just happened to notice the ESC light come on, just for a second.

OP, could this be the same thing that's happening to you?

paisleysdaddy 05-29-2015 09:18 PM

Was it anything like this video? I had this happen on my old JKU and it ended up being all because of my steering wheel not being straight.

I have the same issue on my '15 Willys automatic. I haven't noticed any dash lights come on and it's aggravating as hell. This is the first vehicle I've had that does that and I thought I was having electrical issues. If anyone knows a fix or how to disable it, pls post. Thanks!

I can confirm that cruise control cuts out on bumps. I've just figured it's a safety feature. Never had a problem with turns.
