Interesting phone call, service manager quoted me 7k to install adaptive cruise control on my 2018 compass.... for non Trailhawk compasses, 1700 to change front ends to trailhawk with steel impact bar, they also have to calibrate the radar if it’s removed. Putting on bigger tires? 97 dollars to calibrate speedo, that lets you keep the warranty on everything. The ACC they said they have to change the body control module as well as the drive train module as well.
