Hi, has anyone had any problems with their Cruise Control? Mine's been problematic since I got the vehicle - CRDi, 2008. Intermittently fails, usually after I initially start the vehicle and try to set it when driving at a speed anything over 30mph. I can turn the cruise control on, but when I press the set button it doesn't work. It will however, come on later in the drive. It has nothing to do with the speed I'm travelling, or how I use the vehicle. Hyundai have had it in several times and have not got to the route cause of the problem. They've replaced the switch, but it continues to fail. As it's an intermittent fault, unless they have the issue when they're driving it, they can't diagnose it. Surely something registers in the computer?
The horn has also failed three times. Are these issues interrelated? Finally got the horn replaced on the third failure. I also have issues with the ESP, which turns itself off whilst I'm driving. I'm told the ESP and Cruise control are interrelated. Anyone got any suggestions on what the route cause may be?
