Cruise Control acting up on 2006 Sonata

On a long drive yesterday, I went to use my cruise control, and got an odd set of responses:

Set/Decel button:
  1. When the system was "Not set" ("Set" light = off) I pressed, but no response
  2. When the system was "Set," I pressed to lower speed, but the "Set" light went off (as if I had pressed "Cancel'--but I hadn't)

The above was not consistent. Sometimes I got those errors, other times it all worked as it should.


On/Off button (the back-side one): Never a problem

Resume/Accel: No problem

Cancel: No problem


Anyone familiar with this? Are my buttons going bad? Is my clock-spring wire coil perhaps starting to go intermittent "open" on me??

Thanks.

When my clock spring went bad, the cruise would not work. Deal-breaker for me -- I use cruise ALL the time. I let the dealer diagnose it (ESC light was also on). Once they diagnosed it, I just had them do it since they had the part and I didn't want to mess with the airbag.

Only repair I have ever had the dealer make.

It was about $400. Part was around $150, and by the time they had diagnosed it, the labor was not much more, so I had them do it. I live 75 miles from the dealer, and I had to take it back because I did not notice when I got it back that the steering wheel wasn't straight.

Has anyone ever tried to clean or re-tension the clock spring? Doesn't seem like it ought to be that hard. I did not actually see it, so I don't know.

Mine has been doing that for over a year and it does not seem to be getting any worse. I thought maybe it was just the "set" button itself. If it does not work after pressing it twice, I hold the button and move my finger back and forth a bit. This will normally cause it to work properly.

My gut feel is that it is probably the cruise control switch, itself.

Driving along a straight section of highway, not doing much steering, not doing much braking, the SET light eventually came on after 4 or 5 presses of the button. After that, everything worked fine. Accel, Decel, Cancel, and then hitting SET/ACCEL again got the SET light to illuminate immediately.
