Cruise Control - 2014 Fusion Hybrid

[RWFusion2014]

My cruise control randomly "Cancels" as if I hit the brake. I drive about 80 miles a day and most of the miles are interstate miles. It seems to happen at the bottom of a hill when it is running on battery and should shift to engine. Is anyone else having this issue or have a suggested fix? I have had it i the shop twice but nothing has been found wrong yet.

Does it happen every day on that hill? Does the cruise control number on the dash show up as crossed out as if you had hit cancel?

No not every day. Last Friday cruise cancelled 4 times on my commute. Today not once. Very random bust seems to happen at bottom of hill when engine should kick on. When I set the cruise I get a small green circle to show that it is on. When this happens the green light goes out(as if I hit the brake). Once I realize cruise is disabled I can hit "Resume" and cruise engages again and goes back to set speed.

You do know that cruise will not engage and will disengage automatically below 25 mph or so right? Just curious. :)

[RWFusion2014]

Sure do. This happens on the interstate when I have the cruise set between 65 and 70.

Green light? The cruise control on our dash says the MPH & says "ECO". Can you take a picture of what shows on the dash when this happens?

I believe he is referring to the little green speedometer icon that lights up in the lower left corner of the left cluster when cruise control is on. That icon should stay lit until you either turn cruise control OFF, or turn off the car. It should not go off on its own unless there is a fault detected in a related system. ... Usual disclaimer applies. :)

Oh! I always thought of that icon as gray rather than green lol but now that I think about it...it is green!

Okay, I admit I made a slight error (see disclaimer) in my previous post. The icon only turns green when cruise is actually engaged. When cruise is just on, it is gray. :)

I think that's the wrong shade of green. :)

From the manual (pg 83): Adaptive Cruise Control (If Equipped) The speed control system indicator light changes color to indicate what mode the system is in: See Using Adaptive Cruise Control (page 186).

On (white light): Lights when you turn the adaptive cruise control system on. Turns off when you turn the speed control system off.

Engaged (green light): Lights when the adaptive cruise control system engages. Turns off when the speed control system disengages.

But don't believe me, it says so, right there! :)

If a fault causes it to cancel is there any way to get a read out of the fault?

I would check the brake switch. It might need to get readjusted (I had another car with the same issue you are having and that was the solution).
