...or lack thereof.

Re-engaging the CC, or setting it at a new speed, is very clunky/jerky. I have not had such a primitive CC since my 1979 SAAB. Is this "normal"? I was thinking I was just being picky but then I drove my wife's Tellluride today and it was like buttah in July. The F250 is more like 2- Gravel in February.

To be fair, once engaged, it's acceptable, though not nearly as good as my Rams were.

 

Do you have adaptive cruise control or regular cruise control? My adaptive cruise on my 2019 F350 is as smooth as can be, I like it so much better then the adaptive cruise on my 2020 Tahoe.

 

I use it all the time and haven’t once thought it was clunky or jerky. When I press the set button, the truck maintains the speed seamlessly.

My non-adaptive cruise is not clunky or jerky.
Hit the button and it sets and holds smoothly.

 

The standard cruise control on both my 2020 F-350 6.7L and my 2022 F-350 6.7L is OK without any load. Add a 10k+ RV and drive the scenic route up and down hills in the country and it's a completely different story.

As soon as the truck hits a grade the speed drifts down 5mph to 7mph then finally the cruise reacts. Instead of a smooth transition and gentle application of power, now the cruise overreacts with substantial throttle and a 1 to 2 gear downshift.

I find myself helping the cruise control by adding a little throttle pedal at the start of a grade and then the cruise catches up and begins applying power. This prevents the throttle overkill and 1 to 2 gear downshifts.

I suspect it's all in the PCM/TCM programming being set for an unloaded truck on level ground and not adapting to changing conditions. If you ask me, Engineering at FORD got lazy on this one.

Eventually, I would like to add the adaptive cruise to my '22 with Lariat trim. I've heard it's about $600 in parts if you can find the radar sensor mounting bracket. That should make the braking assist actually do more than a warning if I'm correct?

 

I have both, and have tried both. Once set, it's "fairly" smooth*. I'd give it a 6 out of 10 compared to my previous vehicles (2 Rams, 2 MBs, my older Porsche, an Explorer, need I go on). It's setting a lower new speed where it's at its worst. For instance, speed limit is dropping from 50 to 40. As the 40 is approaching I Cancel. When I reach the new speed I want for the new zone I press + or -. Then it gives a clunk.

*I guess I could add that I live in semi-hilly (not mountainous, but with occasional 8-10% slopes).

 

My regular CC on my 2019 works fine towing or not. Seems the same as my other cars.

You may try disconnecting your batteries for ~30-min to reset your PCM/etc. Who knows it may help and doesn’t cost anything.

Good luck,

Mike

 

Mine has never been anything but smooth when engaging cruise.
Now, on your example of when it is giving the clunk, slowing from 50 to 40 then engaging cruise, are you holding the throttle when engaging after slowing to 40, or are you just pushing the button as the truck slows on its way down?
I always have my foot on the throttle, holding the speed as I engage the cruise.
Your other option is to tap your way down to the slower speed, each tap of the "-" button slows the speed by 1 mph, and does the opposite on the "+" side, 1 mph up at each button tap.
I usually won't do this for a 10 mph speed drop, but often do that for a 5 mph speed drop.

 

To my way of thinking the CC is to eliminate or reduce the use of the skinny pedal. So no, my foot is not on it. I Cancel at the point where I think it will "coast" to the new speed, and then Set the new speed.

I am aware of the +/- 1 MPH feature. In fact, there is an additional feature where, if you hold them fir a full second or so it will move to the next 5 MPH increment*. I almost never use it slowing down, as that will often induce a downshift to slow to the new speed... I do often use it for speeding up.

*Not BY 5 MPH:
53 --> 50
47 --> 45
etc.
or:
51 --> 55
47 --> 50
etc

 

Ok, yeah, it will jerk if you push the button with your foot off the throttle when setting it while coasting down in speed because it will suddenly grab throttle control.
Have only ever done that by mistake.
So, you are seeing totally normal operation, easy to avoid.

 

OK "normal" for an SD I guess. As stated earlier, never on any other vehicle I've owned. Guess I'll have to learn to accommodate the quirk.
