{"text":"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?","pics":"[]","canComment":true}
