2025 Owners: Reverse Brake Assist question

[Dude]

Please only reply if this has happened to you in your 2025 Bronco Sport (don’t reply if it has NOT happened):

Has any 2025 owner experienced their 2025 automatically apply the brakes or issue the audible and/or visual warning indicating an obstacle while backing up when you feel there was no reason for the vehicle to automatically apply the brakes while in reverse?

Notes:
1. In the case where there is no bike rack installed, no trailer or other obstruction blocking the rear sensors and there is nothing close by that could be hit while backing up.

2. This is the section from the owners manual which explains how a false detection could occur but none of the listed items were applicable at the time of occurrence. (shown in the 2nd page in the FREQUENTLY ASKED QUESTIONS section)

This is a blurb about the feature:

Reverse Brake Assist

Backing up in crowded areas or tight spaces can be challenging, but the 2025 Ford Bronco Sport's Reverse Brake Assist feature is here to help. This system uses sensors to detect potential obstacles behind your vehicle and can automatically apply the brakes if it determines that a collision is imminent, helping to prevent accidents and minimize damage.

This has happened to me. It usually happens when I back down a steep incline like a driveway quickly. If I go slow, it is fine.

My conclusion is the thing is sensitive (is that bad?) and it sees the upcoming elevation change as an object.

In that case it violently applies the brakes.

I have seen it give false readings though too... only the bell though... not the brakes.

I AM impressed with the sensors, they do a good job and I think the sensivity is set correctly. I should just go slower.

I am amazed with how well the cross traffic alert works.

BTW... great documentation and great post.

Appreciate you taking time to provide your response and thank you for the nice feedback on the post!

I noticed a similar thing with the auto adjusting headlights (from high beam to low) and a friend of mine with a 23BL noticed the same. When you are approaching a hill on the highway or dirt road and no oncoming traffic, the headlights will often dim. This is when you want them high. I think it is something to do with the reflection or bouncing off the hill. We both turned off this feature and turn high beams on/off manually. I can see how a change in grade backing up could be seen as an object and affect the sensors.
