Collision alert system not working

[jethead]

My 2025 Ranger doesn't seem to provide any pre collision alerts or prevent a collision by applying the brakes. I have selected to highest/ most sensitive setting and I still get no alerts even though I have almost hit another car.

I had my vehicle at the dealer and they said no codes and everything is normal. However, based on my experience with a 2019 Ranger, it is not normal. Alerts should be sent.

Any recommendations on what i can tell my dealer to look at or how they can test the system?

Now that you mention it, of all the newer Fords I've driven the past six years, I have never once seen a pre-collision assist on my Ranger in 30k miles. I thought about it the other day and wondered if the setting was off, but nope, it's on - not sure the sensitivity.

I have never liked the setting as it usually seems to lag behind my own response time, so I don't miss it, but I would like it to function if someone else is driving. I'll mention it next time I'm at the dealer.

I have only had mine come on once and it was on the way home from the dealer in traffic.

I've had the backup come on a few times and it has saved me twice. I do know that you have to move above a certain speed for the brakes to come on.

I have had forward collision come on once, in the 2 1/2 years I have owned it. Saved me from rear ending a car.

I have hedges a few feet outside of my garage that need to be trimmed. Anyway backing out slowly not even 5 MPH if I don't cut the wheel enough I'll run into some branches and the collision detection will stop the truck

Mine comes on every time I back out of the garage, side impact alert from the door then a back impact from the shed I back up to.

I think the systems are more intuitive than in earlier versions. I think, like others have said, if you here the beeping while you are close to an object in a driveway or parking lot, it is working.

Mine came on once for no reason. I then set it to the lowest sensitivity. I hate the damn electronic nanny features.

Thanks for the responses. Does anyone know of a diagnostic the dealer can run on the system to verify it is operating properly?

To be clear, I’m referring to my forward collision assist. All my sensors and backup assist work, however I keep the automatic braking off.

Well I have an orange road cone in my garage so when I pull in the beeps start when I get near to. But anything should work say a garbage can (plastic)?

I do get the parking sensor alerts. What I dont get are the collision warnings and auto braking.

Similar situation happened to me this spring. Haven't had an accident in 40+ years. Forward Collision Assist kept the streak going.

I think you have to be going at least 10-20 mph for the collision warning to work.

I get auto braking backing up when too close to shrubs and I am not going over 5 MPH. Brakes stop truck, loud beep and red warning on center screen.
