Shuttering/vibrating at low speeds

[Azgunguy]

So I installed ACC on my 23 pro and after driving about 150 miles on the highway, I got off and took surface streets. After a fair amount of stop and go in traffic using the ACC the truck started shuttering pretty hard when it would come to a stop or start rolling (sub 6mph). Pretty aggressive vibrating. Any idea what might be causing it? I’m fairly certain it’s related to the brakes? Maybe sticking? The ACC isn’t super smooth and brakes pretty hard when coming up behind a stopped vehicle. To the point where my girlfriend braces for impact, but once it begins to stop its consistent, just decelerates very quickly.

Hi Michael! I can look into your Lightning's concern on my end. To get started, could you please send a private message over with the name/location of your local Ford dealer and your Lightning's VIN?
