NHTSA Complaint #11536859 — 2020 FORD F-150

After work on my way home (clear weather), I was driving my 2020 F150 on the highway with Adaptive Cruise Control (ACC) engaged. Suddenly, I noticed that the ACC system was not responding properly to the traffic ahead, and it was not maintaining a safe distance as it usually does. I attempted to disengage the system, but it failed to respond, leaving me unable to control the vehicle's speed manually. Upon investigating, I discovered that the front camera, which is a crucial component of the ACC system, had failed. As a result, the pre-collision feature was also disabled, putting my safety and the safety of other road users at significant risk. Since the failure occurred suddenly and unexpectedly, there were no warning lamps or messages indicating the malfunction before it happened. The issue was not reproducible after the incident. In the meantime, for safety reasons, I have stopped using the ACC system and continue to drive the vehicle with heightened caution. Further more, after a week upon starting my truck, I got "Front camera malfunction" message, and my cruise control, pre-collision assist, and lane keeping assist are not functioning.
