Hi, all.
My daughter recently bought a 2020 focus with driver assist pack. When using cruise control she notices the car over runs the set speed on downhills. We also have a 2021 escape. Cruise control in this car holds speed everywhere. It's really good. Even on steep gradients it holds speed changing down gears if required. The escape is a slightly bigger and heavier car so not sure why the focus doesn't operate the same. Is there a software update to fix it or is it normal. The focus has the 1.5 compared to 2.0 in the escape. Can anyone offer any feedback on this. Focus has warranty until 2026.

if the escape had the optional adaptive cruise control it uses the rear brakes to maintain desired speed in downhill run. Without this connection to the braking system the cruise can only use engine braking to slow

Cruise control on some cars doesnt tie into the transmission. So my 08 fairmont will back down gears to try and maintain set speed. My mums old 01 ml320 benz did the same. My old mans 02 jag didnt. So cruise maintained speed on the flat or going up hill, but on a decline it coasted. Nothing wrong with the cruise in the jag, it was just how it was in older cars even though it should have been better in the jag.

I just find it weird that they are essentially the same car (albeit different engine) but behave slightly different. Is not a big deal. Just thought I'd see if there were any other new focus owners that could provide feedback.

Mine only overruns by a couple of kph down a decent slope. I will have to try it down a really steep slope to confirm for you how it behaves then.

Let me know regarding steeper gradients but don't go out of your way to check. Thanks.

Can't give a definitive answer yet, mine works really well on one test then not at all the next.
Will keep trying it out. |

Pretty sure mine overruns a bit on cruise and I have the Driver Assistance Pack?
My old Focus (MK3) with just cruise behaved in exactly the same way.

My SA Focus with Driver Assistance Pack overruns on downhill slopes by exactly 10km/h before it tries to lower the speed.
Next time the car is at the dealer, I plan to ask if they can apply the firmware updates being discussed on Whirlpool to see if it improves it. |

I managed to find a steep enough slope to test any system (Greenmount Hill in Perth, for anyone who knows it), but unfortunately I was stuck in a queue of cars. The adaptive cruise was having no problem restraining the car to maintain the gap, but I'm not sure how it would have performed without cars in front of me.
I did see a 4kph creep on a few steep-ish slopes where I was flying solo.
