If there is one safety item that doesn’t deserve any pushback against, it’s the seat belt. Forget air bags that turn the interior of a car into a marshmallow, the basic seatbelt has done more passenger safety. It’s simple and it works. And generally, they should be the last thing you should have to worry about in a vehicle, but if you own a Ford F-150 made between 2015 and now, you might want to perk your ears up for a moment. The National Highway Traffic Safety Administration (NHTSA) has started a Preliminary Evaluation (read: initial inquiry) into the seat belt pretensioners, which might catch fire. Yeah, you read that one right…the seat belt could catch fire. The pretensioners are known to be the root cause of five vehicle fires, three of which destroyed the truck. The fires are known to start as a result of the pretensioner activating during a crash sequence, but exactly how that occurs is still not yet fully understood. The pretensioners are made by two companies: ZF TRW, and….Takata, home of the almost unrealistic airbag recall. No injuries have been associated with this issue and while the scope of five trucks against millions of vehicles sold in those years is a drop in the bucket, nobody new about Takata airbag inflators until after the crash, either.
