Speed bumps/Rough road Warning Chime?

2022- F250, 6.2L lariat with Ultimate package.

Any ideas as to what this is :

When driving over speed bumps (trailing side of the bump) or over rough roads the truck emits a single warning chime. There are no warning lights or dash lights lit when the chime sounds.

I could not find any in the owners manual.

Thoughts?

Thanks.

Any chance you have a door that's not quite closed, etc? Ran across this old thread as well which may have some ideas even though it was Excursion specific... https://www.ford-trucks.com/forums/1...peed-bump.html

We hear similar in the new 2021 F-150 with all the lane holding and such. Lane holding is off, but I-20 has some bad spots and once in a while you'll hear the ding. You kinda wait for the intercom announcement. "DING - The white zone is for immediate loading and unloading of passengers only. There is no stopping in a red zone."

My guess is cab flex causing a momentary open door chime. Switch doesn't stay open long enough for the dash warning to come on.

The early Excursions had some real issues with the door (and rear hatch) sensors, and an updated sensor was offered later on. Hit a bump and all the interior and running board lights would illuminate. I replaced all six sensor on my '01 Limited, and had no problems with them on my '05 Eddie Bauer.
