I just got into a new 2019 Cascadia. On the highway, my speedometer shows me going 65 mph but my truck is actually only going 60 mph. I know this is something for freightliner to deal with but I can't get in the shop for a while. Am I missing something. And when I do get it to freightliner, would it be a quick fix?

Possible the truck has smaller diameter tires on it now than it did at the factory.
It's just a setting in the ecm. The dealer can change it in under ten mins.mhyn Thanks this. -
It's definitely off. I know you're like "no #### sherlock" I have a 2018 Plasticadia and it's speedometer is DEAD on accurate. I am just letting you know that it can be made right.

I have a 19 as well and the problem I am facing is not even Freightliner mechanics know how to fix a 19. They all say they never worked on one before and don't know how to fix anything.
