Ford Motor Company (NYSE: F) is recalling ~4632 model year 2020 Expedition and Lincoln Navigator SUVs. An electrical short may develop in the battery junction box’s printed circuit board that is capable of an electrical current load sufficient to overheat the printed circuit board A short circuit within the battery junction box can cause an engine fire while driving or parked.
“Owners are advised to park their vehicles outside and away from structures and other vehicles, until the remedy is performed,” Ford said in the required safety defect recall documents made public by the National Highway Traffic Safety Administration this morning.
“Some customers have reported a burning smell and smoke from the front passenger engine compartment while driving,” Ford said.
“The printed circuit boards in the battery junction box of the affected vehicles were produced with improper solder mask coverage and limited conformal coating, which exposes a via circuit to water that naturally occurs in the vehicle environment. The combination of any contaminants and water initiates corrosion and dendritic growth that eventually leads to an electrical short capable of an electrical current load sufficient to overheat the printed circuit board. These circuit boards were produced by a supplier that shifted production to a different manufacturing facility in 2020 at the beginning of the COVID-19 pandemic,” Ford said.
Ford dealers will inspect and replace the battery junction box, as necessary, and remove a ground wire. On models equipped with standard-duty radiator fan motors, dealers will also install an auxiliary electrical box with a wire jumper. Repairs will be performed free of charge as required by U.S. safety legislation. Owner notification letters were supposed to be mailed 25 September 2025. Owners may contact Ford customer service at 1-866-436-7332. Ford’s numbers for this recall are 22S36 and 22S48. Vehicle Identification Numbers (VINs) involved in this recall are searchable on NHTSA.gov.
