Veh is a 2019 F-150 XLT Supercab 4x4,

So, I am driving along when suddenly bells start chiming and I get a warning on my instrument panel:

PRE-COLLISION ASSIST UNAVAILABLE - See Manual

I say to myself, "What the hell is the pre-collision assist, where is it and how do I access it? Dig out the manual and begin researching. I check my advance settings and see that in fact Pre-collision Assist is ON. So, now what? More research reveals the system utilizes a radar sensor which is placed behind the grille to detect the distance between you and the vehicle in front of you. Has it gone bad? Hou much will that cost to repair?

I was able to locate, observe and inspect the Pre-collision Assist radar sensor. Lo and behold what to see? The wing of a dead insect was splattered on the front surface of the radar sensor. I removed it by wiping the surface of the radar sensor with a cloth.

The bells no longer chime and and the Pre-collision Assist is back up and operating normally.

I would have been a very unhappy camper if I had had to take the truck into the dealership and pay a $100 Diagnosis Fee + .1 hour of labor to have the bug removed!

 

The government keeps mandating more and more safety gadgets, sonthere will be more and more repairs needed to keep the warning lights off.

 

Very good reminder for all of us that washing the front of newer vehicles serves more than cosmetic purposes.

 

That's a good story with a good ending. I like the thread title too.

 

Our Mazda has that behind (in front of?) the rear view mirror. We get that warning on cold mornings when there is frost covering that part of the windshield.

 

that and the rear end hit warning when towing, trying to back up the brakes lock up or backing in a tight parking lot the brakes lock up
