| Exterior Lighting problems |
I purchase the car in December 2025. Lights were working fine then. Recently I noticed an issue on the right taillights. 2 of the 3 lights were working fine, then later in the day 1 of 3 were working. Until finally none on the right side worked. When pressing the car brakes, using the turn signals to enable the taillights to indicate a right turn, unlocking/locking the vehicle, the taillights on the right side do not function. I took a look at the lights up close without removing anything and saw like if there is moisture/water in the taillights. I have read that other vehicles of 2025 same model have had similar issues. I currently have it at my dealer that my Ford app recommended.
