For the record, our 2022 Touring is terrible at maintaining a set speed. If I set the cruise at 74 mph, for example, it'll vary between about 70 and 76 mph depending on grade of the road. Sometimes it seems it can't even hold a steady speed on flat ground.

However, they realized (correctly IMHO) that maintaining speed regardless of terrain is wasteful of fuel. So they (and other manufacturers) programmed it to bleed off speed in favor of increased fuel efficiency.

Good point, Dave. And the some other moron in the engineering department down the hall caused that fuel saving to go all to hell by letting people bring their living room on the road with them. There went all that fuel savings. There's no free lunch. Physics can be brutal !

Ok, Cruise Control users that are having problems... Do you still have the 3 year or 36000 miles warranty, instead of complaining about the cruise control and not doing anything about it, take it to the Honda dealer and have them adjust the cruise control, it really is a minor adjustment...

Does this adjust problems with speed increases going downhill, or only to adjust to maintain speed going up hill?

It does both, the gain adjustment adjust how fast or slow the cruise control (CC) engages to speed up and stability it to hold the speed constant, both of these adjustments effect one another, they can even cause the throttle to to be really unstable such as going to fast and letting off the gas really fast, causing in 250 msec time in full throttle-no throttle.

Has anyone taken their car to the dealer and were they Able to fix anything tales to ACC?

I obviously didn’t read this post before I bought my 2022 Odyssey Elite - I am also having cruise fluctuation issues. On a standard drive it is constantly fluctuating 3-4mph. On bad days it will slow down 6-8 mph before it decides it is ready to go. Adaptive cruise control is off.

Has anyone had any luck getting this addressed at a dealership? I have been to 2 and both tell me nothing is wrong. One says 5-10 mph fluctuations are standard. The other says 3mph are standard and seem to ignore the video I have of the 6mph fluctuation.

If anyone has been successful in getting this fixed I would love to know how. I just purchased this vehicle in early March and I have been fighting this since the day I drove off the lot to no avail.

Have you taken it in to the dealership? If yes, what did they say?

They can adjust this on their software to your ODY. It is one of the more easier items they can do and not even get dirty. Make an appointment, and tell them the cruise control is not holding speed correctly. To me it sounds like the gain adjustment is set too low. Don't let a pushy service advisor tell you nothing can be done with it, they will try and get away from doing it, however if it is under warranty they must do it.

I have taken it to two dealerships and they both tell me nothing is wrong. One dealer told me it is normal for cruise to fluctuate 5-10 mph. The other told me they would get me more information and still hasn’t gotten back to me.

I get the feeling the people I am dealing with at the dealership have no idea that this is an option. Is there a certain type of technician I should ask for?

 

[DJVAN]

@Eas427
No there is not, and if you only have the 2 Honda dealers in your immediate area, and they are saying nothing c an be done... I would call Honda Customer Care on 1-800-999-1009 , this cruise control is some area that is not too complicated, unless the technician cannot figure out how to adjust a delta configuration.

 

[tedhonda]

I actually had my tech at the service department call Honda Tech and they said nothing can be done. All of us are struggling with the same issue. I.e. We don't know how to get the techs the documentation they need to perform the adjustment. So what we need is some sore of details on how it's done. I.e. is there a document name or number they need to read? Is there a particular program they need to be using? In my situation, I called customer care and they told me to have the tech call Honda Tech but that went nowhere. DJVAN - you seem to know the most about this, any chance you can get the detail information that will help us all - i.e. be our speed savior?

I have not worked on any year of a Honda or model, but have in almost all American produced vehicles (Ford/Chevrolet/Dodge etc...). They all work the same way, not saying it is a exact copy of each other, but the principle is the same.

At a given point of let's say 1800 RPM is 65 MPH. You would select to activate your cruise control to this. The variable is going to be is what is your cars RPM after pressing the cruise control. If your engine begins to decrease in RPM due to going up a hill let's say the engine RPM drops to 1725 RPM, the variable has changed and the cruise control will increase the throttle slowly until the fixed-1800 RPM is reached and than maintains the throttle at that point. After you reached the peak of the hill and start going down the hill, the car begins to speed up the engine, let's say to 1900 RPM, than the variable will remove the throttle until the speed again reaches the fixed-1800 RPM. I have not included any information about what the transmission is doing relative to this as it has it's own programing to look over it. So, the variable changes due to whatever is effecting you vehicle forward momentum, grade/wind make most of the changes, however now we add in the ACC of newer vehicles and they also use their radar with the camera as well. So we can say this has become our third variable to effect the set RPM/speed due to vehicles ahead of you or turning in front of you (INCLUDING BRAKING). If you follow any electronic circuits you could compare this to a comparator circuit.

In the American vehicles, the cruise controls use a adjustment to speed up/slow down the change (RPM) which is called gain in controls, and also another adjustment called stability if the changes are taking place to fast. When you adjust one, say you adjust the gain more for a faster RPM change value, it effects the stability of not overshooting the RPM desired, so it involves adjusting both until the desired outcome is met. With what limited resources I have the only real thing they talk about on ACC systems is to insure that your windshield is clean if front of the camera and that the radar unit is not dirty. It's not good info as I do not believe that no one takes their ODY out 4-wheeling. But if the camera or the radar does not work properly it will not allow the ACC to work at all. I do not have a HDS to look at to see what the HONDA people use to see if their is anything on the ACC or just raw cruise control to adjust, but if their was they would have to be able to understand what is gain and what is stability and how they effect the set point.

I don't use the ACC anymore. Way too annoying. But what you are saying is more hypothetical that the Honda Techs SHOULD be able to do versus what they actually can do? In chatting with the master tech at the dealership, he said they would have to update the CPU setting which is something he said they can't do. That makes sense to me as if there were software updates, whatever they do would be overwritten.

We had a 2020 Odyssey (our current one is a 2023) and that one did not have this issue. Nor does our 2022 CRV hybrid.

Something of interest though, our auto engine stop wasn't working, i.e. it never shut off the engine, and the determined it was the battery. It was something to do with the voltage, not sure. They did give us a new one. Kind of crazy we had that issue after 8000 miles.
