Lincoln is recalling 35,328 Navigator full-size SUVs because lights on their exterior mirrors could short circuit and potentially start fires.
The recall covers 2015-2017 models with LED puddle lamps on the exterior mirrors that project the Lincoln logo onto the ground when the driver approaches and unlocks the vehicle. Known as welcome lighting, this sort of feature has become popular among luxury brands in recent years, but in this case the lighting elements could be faulty, according to the NHTSA.
In the affected vehicles, potting material used on the lamps did not properly adhere to the wire terminals, leaving gaps that could allow water to penetrate the lamp and come in contact with printed circuit boards. That can lead to corrosion and short circuits, which may go undetected because the system that checks for them was set up for incandescent lamps rather than LEDs.
A short circuit can allow heat to build up and thus increases the risk of a fire. However, Lincoln told the NHTSA that it is not aware of any accidents or injuries related to this issue.
The LED lamps were added as part of a 2015-model-year refresh of the Navigator, which was then completely redesigned for 2018. Lincoln’s biggest and most expensive vehicle gets another redesign for 2025.
Instead of fixing the potentially leak-prone lamps, Lincoln is having dealers simply disconnect them. That service will be performed free of charge, and owners who have related work performed on their own dime may be eligible for reimbursement.
Lincoln plans to mail owner notification letters Mar. 24. Owners can also call Lincoln parent Ford’s customer service department at 866-436-7332 for more information by mentioning recall number 25S08, or visit Lincoln’s recall website.
