Hey guys,
Just bought my wrangler about two weeks ago and am in love with it! My question is I have like a 30 mile commute to work and is all highway and so I just sit back and throw it in cruise control. But my problem is I've had it where I would have it on cruise and hit a big bump somewhere in the road if it is uneven pavement or a typical bump on a highway and the cruise control disengage. I can hit resume and go back up to speed but wasn't sure if that is a safety thing or if anyone else had this problem?

2014 JKUR here, and I haven't had any such issue in the 13,000mi I've put on it. I use my cruise control a LOT.

Yea I have only put about 2000 miles on it but it has happened I would say maybe 3 times and wasn't sure why. Obviously still under warranty but before bringing it in, I wanted to see if anyone else had the problem first

40 k miles on my 3.6 JKUS. Never had an issue with the cruise cutting off like that. Ever. I think you might be tapping the brake pedal?!? Maybe the brake light switch attached under the dash at the pedal might need adjusting. You might have someone follow you and see if your brake lights are illuminating when you hit big bumps. Sounds like the likely cause to me.

if you hit a bump where the computer thinks there is slight wheel spin it will disengage the cruise as an anti-slide precaution.. it is part opf the ESP (stability program).

mine will do it sometimes if i hit a pothole or transition onto a bridge that has a metal strip for the threshold esp in the rain where it might be slightly slick..

I have a 2013 and it's the same way, once you hit a bump it turns off for safety reasons

^^^ this.
Mine has done it a couple of times. With the solid axles and pretty stiff suspension the drive wheel may come off the ground enough to spin.

Awesome that is usually what happens, when I hit a pothole or on a highway with a bridge. Thanks guys

I know I'm about a year late to this thread. I have a 2014 that I bought in January of 2015. I had noticed that the cruise would disengage sometimes when hitting a bump. Mostly when going over a bridge that's not level with the road. I figured it had something to the computer and the ESP. Thanks for confirming that.
