Turn off PCS (pre-collision system) Then the warning won't keep on popping up.Yes it happens on the LCLC trim as well. I filed a complaint with the NHTSA but never got a confirmation -- it's super annoying when you're dealing with difficult terrain and your display is locked up waiting for you to hit the return button every five seconds.
I've been tempted by the Bronco since it came out. I was waiting for the hybrid/plug in hybrid that they've been testing since that first year but never released. (Plus, owning a Ford that was in the shop so often is what drove me to buy my first Toyota, and I've never gone back. Hopefully they are better now!) The Land Cruiser is probably better for me anyway though. But I'm for sure jealous of the ground clearance. I saw a video a while back with an informal comparison of a few offroad SUVs including a Land Cruiser, some Jeep, and a Bronco, and they concluded the Bronco was the most effortless on difficult offroad trails.
Suggestion: get some kind of tie rod reinforcement, that seems to be a really common failure point on the Bronco.
Unfortunately it doesn't stay off, so if you shut the car down, you will need to turn the PCS off again.
