NHTSA campaign 19V808000
Hazard
Ford Motor Company (Ford) is recalling certain 2018-2019 F-250, F-350 and F-450 Super Duty trucks. The Daytime Running Lights (DRL) may not dim when the headlight switch is moved into the "On" position. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Consequence
DRL that cannot dim may reduce the visibility of other drivers, increasing the risk of a crash.
Remedy
Ford has notified owners, and dealers will reprogram the Body Control Module (BCM) software, free of charge. The recall began November 25, 2019. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 19C10.
