Some 2022-2023 F-150 Lightning vehicles with Lariat/Platinum trim levels built on or before 06-Jan-2023 and 2022 Expedition vehicles built on or before 28-Oct-2022 may exhibit a concern with the audio system inoperative or no access to FM, AM or satellite radio modes. This may be due to liquid ingress in the audio front control module (ACM) from the top of the dash area. To correct the condition, follow the Service Procedure to replace the ACM and seal the dash seam.
