I just noticed that there is water trapped in the rear light bar. Anyone else see this?

Yes, I posted pictures of my tailgate lights, all have water too. I've got an appointment for the 9th with my dealer.

I've seen a few posts about this now which is more than enough to indicate a trend, sadly.

I am on my second replacement lightbar. The Dealership has been great about swapping it under warranty however, it takes about 3-4 weeks for them to get a replacement from the mothership.

Great. Guess I'm calling the dealership on Monday.

I noticed the water buildup a few weeks ago, and today the white led portion stopped working and the entire red part flashes spartatically.

I guess it’s good others are having the issue too, that likely means Ford will have no choice but to cover it

This is now a safety issue... Can't have something that looks like a brake light randomly flashing while driving. What's annoying is, my dealer won't entertain the idea of ordering the part before seeing it.

Have you lost your rear camera yet?

Same thing happened to me, and then eventually I lost everything - tail light, reverse light, and my rear camera. Not fun

Good morning. Would you send over a private message with your VIN and the name and location of your Ford dealer so I can look into this light bar concern on my end? Thank you!

Same issue here. I'm out of the country, but dealer needs to see the car first. Pictures have already been shared confirming the issue with them.

I also have the same issue and very disappointed. Dealership called me today and informed me of an ETA of 12/28 for the part. This is so annoying and I agree is a safety issue with the tail light already burnt out and the reverse light flickering. I know the backup camera is next to go out ?

So what's the problem? Are there seals that are damaged or not properly placed during manufacturing or is there an inherent leak due to bad design (probably not)?

Well, I got water too. Seems to be getting worse each day.

Called the dealership. They said I need to bring it in to get checked out before the can order the part under warranty.
