“Pre-collision avoidance not available”
Just fired my truck up and this message displayed on information screen. I was simply moving truck and have not driven it since I saw the message. Anyone ever seen this message? I obviously have the adaptive cruise and collision avoidance feature.

Fortworthian, it's happened to me a couple of times but corrects itself on the next start. Coming from an '03 F250 (the truck I was never going to get rid until it was stolen in Dallas) I've come to accept my '17 F250 KR as a 4x4 computer! RP

My collision avoidance will disable starting in my garage as I have to pull right up to the front wall to fit in. Outside the garage no issues on re start. Must be due to the lack of space at the front of the vehicle. I wonder if starting with snow covering the front of the vehicle does this?

I've had this happen on my 17 F250 several times. It also happens on my VW GTI. In all of the cases it has happened when it is cold outside.
On the GTI, you'll be cruising along and all of a sudden ACC and the collision sensors all go away. After awhile, they come back. On the F250 they never come back unless I restart the truck.
They happen so infrequently, I've not even bothered talking to the dealer about it.

Ive had it happen 3 times in 2200 miles, always fixes with a restart. Once it happened mid drive and totally disabled all use of cruise control. Pretty annoying, but not consistent enough to take to the dealer. Sounds like it may be fairly common though

Seat belt chime
My 2019 f350 has 500 miles on it...I recently turned off the seat belt chime and now it’s telling me the pre collision warning system is not working....can anybody tell me if these two are related to each other?

Pre-Collision Assist Not Available
Did you ever figure this out? I am traveling and seems to always keep happening for no reason and I have to pull over and shut the car off to fix it.

Check your batteries, separately of course. As in, disconnect them and check them individually. These trucks can do weird things when battery voltage dips even slightly. I was getting the same warning at times. Batteries seemed fine....two weeks later, truck wouldn’t start while at work.
Replaced with two AGM batteries, no more weird electrical phenomenas.
