    I drive a 2021 Freightliner cascadia and I've had constant issues with the functioning of the cruise control and ecoast features on this truck. The most common issue has to do with the fact that the cruise control will not maintain the set speed, it tends to either slow down from the set speed for no particular reason or speed up beyond the set speed for no particular reason. In addition to that it randomly engages the ecoast feature at the most inappropriate times, for example I will be going uphill and under the set speed and it will randomly shift into ecoast slowing me down frankly to an unsafe speed more often than not. I commonly have my cruise control set at 65 mph and it will often times find myself going 5 to 10 mph under that speed, due to the cruise control not functioning properly, and then the ecoast feature will activate slowing me down even further.

    Is there any type of reprogramming or other solution to these issues? Please advise

    Yes that can be changed
    Either by computer or replacing TCM.
