Of all the things that can start a fire in your truck, I’m guessing you were never really worried about the seat belts.
Between April and October 2017, Ford knew of four reports of localized interior fires that occurred on 2015-2016 F-150s after the seat belt pretensioners deployed. An investigation on the four trucks was opened that focused on the front seat belt pretensioners (both retractor and lap anchor), electrical wiring, insulation and carpeting.
Pretensioners use a small explosive charge to lock the seat belt in place during an accident. Except, the F-150’s charges aren’t small and have been producing “excessive sparks” that smolder on interior panels and sometimes start a fire.
The recall covers both the Regular and SuperCrew Cabs.
