hey all
Does anyone have an issue with the rear sensors giving false alarms after a hard rain? If so, what did you find? Thanks

I saw this on my 2016 Roush F150 and the only resolution I found was to replace the problematic sensor under warranty.

I had a same issue with my previous gen F150, only fix is replacement of sensor and/or connectors (water leak)

I have had this on ever vehicle I have owned with rear sensors. Rains hard enough where water on a sensor causes it to give a false reading. Dry or clean them and have no issues.

We have had 3QX80’s and 2QX56’s and every one would effect the rain sensors when a hard rain. Fixed always dried immediately.

I have a 2018 Raptor that I purchased in June 2020. Ever since, my driver rear has falsely gone off whenever there's a soaking rain and it's very wet out. I've had it to the dealership, they've replaced the sensor and still it continues. The inside of bumper is clear and the connection is packed with dielectric grease. I've also double checked the sensors and this one is no more wet than the others and wiping it off doesn't help. This leads me to believe there's some issue in the wiring/harness given the persistence of this problem on this sensor only. I've escalated to Ford and they just reference that service bulletin (GSB 19-7027) and ignore me when I continue to say it's a problem. Has anyone else had this particular issue / gotten any headway in diagnosing it and/or getting it fixed?
