2011 Hyundai Elantra steering wheel controls. The cruise control and the trip button doesn't work

SOURCE: steering wheel controls

Replace the clock spring, or check all the cabling and plugs first. If you are inexperienced take it to an auto electrician, otherwise do it yourself but disconnect the negative battery terminal for 2 minutes prior to opening the steering wheel to check the plugs, as not doing so could cause the airbag to go off. In addition you can also take out the airbag fuse. Check radio control plugs and close it up again and reconnect everything in reverse order. If that doesn't fix it, then have the clock spring replaced professionally, its too much mucking around if you don't know what you're doing.

This works...the cruise is directly tied to the brake lights...when I replaced the brake and side light bulbs on my 2004 Santa Fe,,,the cruise started working with no other adjustments. It must complete a circuit or something.

Replace the Clock spring. It is mounted behind steering wheel. It alows electrical connection while the wheel turns.

I would get the owners manual out and find out where the fuse is for the cruise control cause there is a pickup switch for the cruise under the hood by the throttle body when it is engaged you don't have to have your foot on the pedal

So after you push the button and then press the set button in the steering wheel it does not get into cruise control ? It sounds like a minor electrical problem. If you have warranty still I think the dealership should fix it for free.

Sorry i have not been able to help you.
