The problem is that the latch pawl spring tab can crack and eventually fail. If it breaks, someone would have to make several attempts to close the door. If it does close, the door could unexpectedly unlatch while driving. As a warning, drivers would see the "door ajar" light illuminate.
The recall only affects vehicles currently or previously registered in warm weather states.
Ford learned of the problem on August 16, 2023, after an issue with a 2016 Fusion. The automaker worked with the supplier to investigate the situation and identify the number of potentially defective parts. As of October 18, 2023, there have been 14 warranty claims and 39 vehicle owner questionnaire complaints about door latches failing or doors opening suddenly. There have been no reports of injuries related to this issue.
The Blue Oval believes that about one percent of the 45,173 vehicles are affected by the problem. To fix the problem, dealers are checking the door latch date codes to see if they're from a specific time frame. If even one is from that period, technicians would replace all four parts. The new parts use a modified spring pawl tab that's stronger than the original components.
