Hello everyone,
I have an issue due to the keyless entry module that seems to be damaged from water ingress. Does anyone know where the water comes from?
 
Model
Fiat 500x cross plus
Year
2016
Mileage
33000
I've not had this problem with my 2015 500X so can not really say much other than the control hub is located in the rear boot wing area. This would suggest the water is coming from either the rear light unit, rear quarter light window or possibly from the cable loom to the roof antenna and tailgate.

Unless anybody else can give details then I guess you are to have to investigate in detail yourself.
 
Very hard to determine without seeing the car
Water will always find a way. Check the pipe to rear washer, it’s hard plastic, rather than flexible pipe, and is a known fault on renegades for spurious water in rear footwell, boot and a leak under front wheelarch
