I have a 2018(5 month's old GT). I noticed yesterday when I left for work that my race track was not working. I called the dealership and they said to drop it off since it was a safety issue(I leave for work when it's dark and return home when its dark, so no tail lights). When I dropped it off last night, the service adviser noticed that the whole lower section of the light was filled with water. I called them @ 1pm today to find out what was up, after being on hold for 18 minutes, they told me that they were going to do a 'repair' to my tail lights. I told them under no condition would i accept a 'repair' The LEDs were submersed in water and it would not be a question of 'if' they corroded and failed, but 'when'. They already weren't working, what made them think that it was going to get better? Needless to say, I spent 90 minutes on the phone with FCA claims and was disconnected twice, and I am still awaiting a call back from them. The vehicle is at the dealership, 53 miles from where I work, and it is now 4pm and it looks like my vehicle isn't going to be fixed any time soon. Not a happy camper
