Hello,

I am trying to find out if Ford's cruise control has gotten crappy, or if mine has problems in my '06 F250.

When I set the cruise, it goes about 3 MPH above what I set it at, then drops to about 3 MPH below, then it eventually stays where I set it. That is until I come to the top of an overpass or other small grade, then it is back to about 3 MPH over again as I reach the top and level out, then going back to where I set it.

The cruise control in my previous Ford trucks (83 & 91), as well as my 82 Mustang, 85 Lincoln, wife's 97 Toyota and the 2013 Chevy rental I just had, works fine. Where you set it is where it stays. Of course going up or down a steep grade, they all are going to lose or gain speed.

Anyway, I have taken the truck to the dealer twice for the cruise control. The first time is when I got the truck in '08. They replaced something else non-related, and said that would fix the cruise. It did help marginally, as the fluctuation was +-4 MPH before. I just took it in again before it goes off warranty, and they said the cruise is operating normally.

So, there's my story. Is this normal, or is something wrong? Thanks.

 

The cruise control on the 05-08 Super Duty's are terrible for doing this. Fogetabotit.
