Cruise Control

Mine works fine, but I have the 2.4 liter with the 9-speed autmatic transmission. Hopefully someone can help you with your issue.

This has happened to me several times, and it seems to always be right after I've had to cancel the cruise control and make an abrupt change in speed, or if I try to engage it while still under acceleration. If I give it a minute, it always starts working, so I'm wondering if it might be some kind of safety feature.

miked2,

I would recommend bringing your vehicle to an FCA dealership for a formal diagnosis. With your concern being intermittent, I would also recommend taking a test drive with someone at the dealership in order to demonstrate what you are experiencing. If you would like assistance in scheduling an appointment, please PM me your VIN, contact info, and dealership info.

I know this is an older thread but I just took ownership of my Renegade last week and I too have experienced this issue. There doesn't seem to be any rhyme or reason to it so far as I can tell so I'd be curious to see what you found out.

This issue hasn't happened to me in awhile, but I discovered that whenever it does, all I need to do is press in the clutch, then release it again (rev-matching as necessary, of course.) The cruise then works fine.

I discovered this because I had a Nissan that had a sticky clutch switch, and sometimes the cruise would refuse to engage until I jiggled the clutch pedal with my toe.

So it seems that the cruise is not engaging because the computer thinks the clutch is down. This is most likely due to an intermittent communication error or an intermittent signal from the clutch switch. If it happens again I'll stick my head up under there and scope out the clutch switch setup.

Hey, I remember reading somewhere on this forum someone complaining about the cruise control, that the vehicle couldn't maintain the set speed. Well it's all about the tires and the traction you have. I had the same issue with the all season tires. If I set cruise control to 50..the vehicle would mostly do 49. Well now that I have winter tires in colder conditions, unless I'm going up a hill or have high winds, the vehicles maintains the desired speed nicely. So in short, if you live in a warmer climate consider summer tires for the best traction, all season tires are somewhat of a compromise between winter and summer...and this pertains to all vehicles.

I don't really have any issues with mine (automatic), other than maybe every fifth time, it won't be able to match speed. Like I'll set it to 65 MPH and it will be either one or two MPH under that & never "catch up" to 65...it will be content to cruise along at 63 or whatever. My highway driving is fairly flat & consists of about 40 miles of my daily work commute. No issues other than that, simply have noticed that sometimes it's 1-2 mph lower than I set it to from time to time.

Take your foot off the gas pedal and then push the "set speed" button. The pedal is "drive by wire". And for simplicity, cruise is the same. You are trying to send two signals at the same time: the pedal will always win.

Thanks for this, this works. On those occasions when the CC will not set, letting off the gas and pressing Set will do the trick, so I don't have to clutch in. But other times I can successfully set the cruise under throttle. And on those same occasions when the cruise will not set, quickly blipping the clutch will also work, and allow the cruise to set under throttle. Weird.

My 2017 Altitude (4x4 9-speed auto) is doing this and the dealer conveniently can't recreate the issue. Has nothing to do with how much or how little gas I'm giving it. When the issue occurs, I get off the road, shut down, restart, and it magically goes away until it happens again.

Dodgy clutch and/or brake pedal switches can be the culprit for CC not engaging.

I have 500 miles on my 2017 Renegade Altitude 1.4L 6MT and experienced the same problem. I believe there may be something to the clutch switch explanation. The cruise comes on but the set does not work. This happened after I cancelled the cruise, and it has not worked since, even after shifting and operating the clutch.
