Hello
my I recently purchased my 2018 Ford Escape, and shortly after purchase I started getting indicators on my dash for Trailer brake and turn lamp faults. I don't hook up trailers. I took it to the dealer and they claim it's because the hook ups got wet. I've checked many times and they were dry and secure. Is there a way that I can just disconnect the tow system as I don't intend on ever hooking up a trailer to my car anyway!?.

Thank you!

 

Get a capable scanner to find out the exact DTCs.
What else you can do is to ALWAYS on ANY cars on earth, doesn't matter it's old or new, apply bulb grease or dielectric grease on all lamps. Since your Escape already came with LED tail light, so I don't think your previous owner upgraded from halogen to LED and triggered the errors. Before applying the grease, clean first using electrical contact cleaner or 91% isopropyl alcohol.
Tow system can't help you with that.

 

But my actual lights aren't affected. They do operate as normal even with these triggers. I made sure to double check and see if my brake and signal lights are still operational and they still do with no issues. It's just that warning primarily when it's raining or after it has rained. Dealer claims it's because the trailer connectors got wet however last time I checked they they were dry.

 

Sometimes you can't tell visually. For instance, any flickering on the bulbs during cold start while warming up, next time when you get home, before you turn off the engine, turn all lights on, go outside and check. There are cold and warm bulb checks that the car computer is very sensitive and picky about the voltage draw.
If everything looks good just get a capable scanner that can clear and do a reset on Ford's specific DTC, or read to find out the exact trouble codes.

 

When you checked the trailer connectors, did you look at the plug and where the wires are connected to the plug ?

If any road salt dust got in there it becomes conductive and can cause all sorts of problems.

 

I'll take a look into that as soon as I can. It's been raining here on and off all day so unfortunately the ground is currently wet and soggy under my car right now. Once it dries up a bit ill go underneath it and check.
