Default 2019 chassis cruise control issue

We picked up our 19/19 U24MB on June 21 in Sacramento. Drove home to the CA Central Coast along high 5 and found the cruise control (Distronic Plus with Steering Assist) did not function consistently... The system would not always 'turn on' and when it did the system would arbitrarily stop functioning with a warning in the center screen stating 'Active Distance Assist Canceled'.
Took the Unity to the local Mercedes shop and they used an afternoon attempting to diagnose the issue with no success. Service manager took me aside and mentioned this was the first 2019 Sprinter chassis they had seen with all the goodies-- their typical Sprinter is a 2500 bare bones work horse.
Anyone else had cruise control issues on the 2019 Sprinter chassis and if yes, what was the remedy? Local Mercedes shop is sending the information collected to MB for assistance. BTW - there were no codes present.
thanks - BruceC

Sorry for your troubles.
We picked our '19M-B/'19U-TB also on 6/21 (Colo Spgs) and the
adaptive c.c. seems to work as well as in our vehicles.

This is why some of us would never be one of the first to buy something that complex. Unfortunately new technology and design is released before techs get information, training, and experience on the new model you just bought. R & D uses you, as it's first "real world" customers to test the vehicle and then you discover your stranded miles from the nearest service center that doesn't have the parts available anyway. But somebody has to be the guinea pig. "What doesn't kill you will make you wiser but flat broke". Keep us posted.

We picked up our Unity with the new chassis on June 26th and have driven it about 500 + miles. The adaptive cruise / Distronic Plus works great on our rig. This is the 3rd vehicle that we have owned with adaptive cruise and this one is as good if not better the others that we have used.

I had a similar experience with a Damiler Chrysler Jeep Grand Cherokee years ago. A software update corrected the problem.

I picked mine up June 24 in Holland and now have 2,500 miles on it. We have seen the adaptive cruise cancelled message a few times. In our case it is triggered by raising off the drivers seat to shift or stretch. When the car senses too little pressure in the seat, it cancels the cruise. Like any newer airbag equipped vehicle it has weight sensors in the seat used to deploy airbags with the optimal force to protect the occupant. Apparently Benz feels the need to monitor this so that folks don’t try to change drivers or make a cup of coffee while using the adaptive cruise and lane tracking to drive the rig - just my guess. After we figured out what was triggering the cancellation, it never happened again.

This sounds similar to an issue I had when I picked up my 2019/2019 CB from Sacramento the other month, almost certainly before you. I had a message saying "Active Brake Assist disabled" or something like that.

I took it to MB of Fairfield and they updated the software. All fine now and 2,500 miles in.

Thanks Chris... I may end up going to Fairfield as the local Mercedes shop is clueless.
