Intermittent Cruise Control Function

[dtilley]

I have the same problem. Cruise control Intermittently will not work. Lately it will not work at all. As most of my retirement money goes to truck payments and repairs, I cant just take it to the dealer. I have searched a lot of posts, and I assume all are valid replies. From connectors not making good connection in the brake related circuits, to the clockspring, to the brake pressure switch. One dealer did read the codes for me, while buying tires, and that pointed to the brake pressure switch. I am going to replace it this week hopefully. Not sure this is appropriate, but I want to add that my 08 F250 Super Duty diesel, is plagued with issues. First, the electronic throttle failed on me after midnight moving a load of frozen beef from West Virginia to North Carolina. Had it towed, and the dealer found that a harness had rubbed against the driveshaft, and exposed and shorted the wires. I could not see how it was possible, but there ya go. Then the remote mirror switch failed, and I just replaced it for the second time. Then the popular radiator failure, just after warranty expires to the tune of $1700. I had one injector fail and replaced under warranty. And the water seperator unit failed and was replaced, and there has been no water discharged from it during monthly checks, in over a year. Little concerned there. The first oil change revealed a loose bolt in the oil pan, which led to a cab off, to remove the oil pan, only to be told it must have been a spare bolt. No sign of where one was missing. Take all of that, and the delicacy of the exhaust cooler and egr system, I am beginning to miss the 2000 7.3 which had 231K miles with no issues. The 08 is a beautiful truck, Ford did a great job with getting so much from a smaller engine, and the way the computer works to manage the tranny and engine while towing up and down mountains, is outstanding. But I have to wonder if it is going to be worth all the expense and dealing with all the issues. As far as having so many electrical related issues, has this become common with Ford? Comparing that to my 2002 Honda with nearly 300K miles, and absolutely no issues really makes me wonder what is going on with Ford truck

Not that many people have electical issues. Overall the truck and motor have been pretty darn good considering the EPA mess that was mandated.

EGR coolers are actually much better than previous ones.

Radiators are the weak point but most of that ha calmed down overall with the strict maintance of the cooling system.

Had the same problem with my 2010 F250. Dealer fixed it under warranty. Was the pressure switch. In the beginning the CC would not work infrequently. Got progressiveky worse. By the time I took it in the CC wouldn't work at all. The service writer said that the problem may effect the brake controller. I didn't notice that and I towed several time wtih it not working.
