Updates to ACC

[Jim-Florida]

My 2020 Ram 3500 will not allow me to engage Adaptive Cruise Contol until the speed is greater than 20MPH. This behavior just changed as I was previously able to engage the ACC upon releasing the break at a stop. Did Ram somehow update the software over the air or is there some setting I may have changed? The screen even briefly reports the ACC speed control which is a new behavior.

Cruise control normally won’t let you set a speed below 20mph. Are you saying before you could set cruise control speed below 20mph?

If ACC is set to say 30mph it will bring you to a stop if your behind someone, and will start going again.

My wife's 2016 Jeep Cherokee has ACC. You can not INITIALLY set the cruise control, or ACC below 20 miles per hour on her Jeep. Once the ACC is set and running, if you let it bring you to a stop behind another vehicle at a light, and don't touch the brake pedal, you can press RESUME when the vehicle in front of you starts moving and it will engage and begin driving you away again. The ACC uses the vehicles computer controlled braking to stop you when engaged and it's sooo cool I scare the crap out of her every time I do it.

Mine has never worked below 20 mph.

While using acc could you before and can you now while acc is engaged come to an acc full stop due to a vehicle stopping in front of you and have the truck resume to the set speed by pushing resume or resume if the full acc stop was under 5 seconds and the vehicle in front of you moves forward.
