Here's the info from Ford: Ford is issuing a recall for approximately 2 million select 2015-18 Ford F-150 Regular Cab and SuperCrew Cab vehicles in North America for driver and front passenger seat belt pretensioners. Ford’s investigation found that some front seat belt pretensioners can generate excessive sparks when they deploy. When sufficient sparks are present, gases exhausted inside the lower portion of the B-pillar by the pretensioners may ignite. If this gas ignites, components behind the B-pillar such as insulation and carpet may subsequently catch fire. Ford is aware of 17 reports of smoke or fire in the United States and six in Canada. Ford is not aware of any accidents or injuries as a result of this condition.
