Tail Light Switch problems of the 2018 Ford F-150

I took my truck to the Ford dealership I purchased it from because the tail lights stopped working. The service manager informed me that water was in both tail lights and had to be replaced for $3,000. My truck is a 2018, has only 18,000 miles and well taken care of and no accidents. The service claimed the water got in because of damage to the tail light. The marks he pointed out on the tail lights were very light scuff marks and could not allow water to get inside. They would not cover the replacement because of the scuff marks. I went on a Ford forum and found that there had been plenty of other 2018 (and other years) that had water in their tail lights as well. The trucks that were out of warranty just remove the tail light, drained the water, applied silicon around the seems of the tail light and had no issues since then. I've attached pictures. You'll see that there is no way water could have enter where you see scuff marks like the service manager claims. The pictures are the left and right tail lights. . Read more...

Had recall done for daytime running lights issue now when daytime running lights are activated tail lights, license plate lights and front parking lights also are activated. Dealer cannot reprogram to turn off tail lights plate lights and parking lights. I feel having tail lights on constantly may cause people behind you to think I am breaking. Do not see many if any vehicles with tail lights on during day light hours.

Tail light assembly leaks water causing the bulb to blow. It accured twice in the last 6 months.
