NHTSA Complaint #11556685 — 2022 FORD F-150 LIGHTNING BEV

The adaptive cruise control is supposed to adapt to the speed of the vehicle in front of you as well as adapt to the posted speed limits as they change. When driving on the highway, the adaptive cruise control will read the exit ramp speed limit while you are driving through on the highway and immediately drop. So while driving at the posted 65 mph my truck drops down to 25 mph. This has strangely happened on occasion when driving under an overpass - my speed dropped from 65 mph to 45 mph. This happens with no warning. You cannot predict when it will happen. I was driving in Maryland on Route 81 which is a MAJOR truck corridor, was driving 65 mph as posted and as I passed an exit ramp, my speed dropped to 25 mph. A tractor trailer behind me immediately blared his horn and continued to blare his horn while he passed me. I contacted Ford through their online problem chat. They never heard of this problem. This is not true because the Ford bloggers talk about this online. The Ford Representative suggested I have it checked at the dealership. I went to the Ford dealership and they said they didn’t have a fix. Just don’t use your cruise control. This defect will definitely cause a major accident, it’s just a matter of time.
