I just tested my truck on the way home from work today, and discovered mine has the runaway cruise control feature also.
It comes down to this as well, not all our trucks have the same cruise control system. I would expect Lariats to not have the adaptive cruise control that King Ranch and Platinum trim levels have. The 2018 F150 Owners Manual actually has sections for each--see the 2 different images attached below.
So, it could be that these 2 different systems behave differently with each having different button lay out; however,
has a King Ranch as do I and he is not having this issue and I am.
Regular cruise control makes this statement in the Owners Manual:
"Press and hold SET+ or SET-. Release the control when you reach the desired speed."
Adaptive cruise control makes this statement in the Owners Manual:
"Press and hold RES+ or SET- to change the set speed in large increments. Release the control when you reach the desired speed."
... Bob, what trim level is in your truck?
Is there anyone without the adaptive cruise control, and are you also experiencing this issue?
This also has me curious how the truck will behave if I have cruise control set and press and hold down "SET -"...when I release the button will the truck go into runaway deceleration down to 0 mph? Interesting...will have to test this out later tonight and report back on that.
This seems like the next FSA that will be published, and I would guess the next time all our trucks are in the shop they will road test for this and apply whatever fix is needed. I guess
and I will be the first to report and get this turned into the next FSA for safety recall reasons.
