I left for a trip last week and get on the expressway, no cruise. I tried to get it to work for 15 minutes no luck. It wouldn't even give the message on the dash that it was turning on. Stopped about 2 hours later, get back in and try it and it worked fine for the next 4 hours. On the way home same thing, not working. After several attempts I got it to work and it worked for the rest of the ride home. I have put 90% of my 15,000 miles on this truck on the highway because it is not a daily driver, sits inside on concrete in a heated barn when not on a trip, never driven in salt so corrosion shouldn't be an issue. That being said I am a big fan of cruise control and use it whenever the situation allows so operator failure can be ruled out I know how to use it. I'm just wondering if anyone has had problems with the cruise because when I take it to the dealer it will be "We couldn't get it to do it, bring it back when it doesn't work at all". I don't want to be on my way to Florida when it fails for good. Any ideas?
