1. The monitor on the vehicle went black on 2 separate occasions so far while the vehicle was moving. The screen rebooted but causes the retractable running boards to be locked in the up position. In order to address the running boards you must go into the settings and adjust the running boards from off to automatic. 2. During use of the active assist, the vehicle on several occasions has just suddenlt decelerated to 45mph regardless of the speed that was set. This has occured with no vehicles infront or to the sides on straight roads.
I purchased a new 2022 Lincoln Navigator reserve l and just took a 3000 mile road trip and used their active glide driver assistance extensively and have uncovered a major safety issue with their system. The issue I found is that when using the adaptive cruise control feature the system will sometimes read a car in the adjacent lane as moving in front of my vehicle and apply the brakes very hard causing my car to immediately and strongly slow down at highway speeds - with other cars behind me. This happens mostly on curves when the straight line of sight sees the car in either the right or left lane next to me at about a 20' distance. There is no warning of brake application and can make the driver lose control. I was almost rear ended multiple times. I know the driver assistance requires the driver to be attentive - and fortunately I heeded these warnings. It appears my vehicle is trying to very quickly acquire the distance between my vehicle and what it thinks is a vehicle in front on me. This is a major issue and will lead to accidents.
