For all the F series Ford owners, Ford has a recall on about 800,000 Ford trucks due to block heaters catching fire. My son in laws truck burned to a crisp on Friday due to the block heater catching fire. He had it plugged into the house. His was a 2017 F 150. I believe the F 150s from 2015 to 2019 are affected. Also F series heavy duties from 2017 to 2019. The damage was a complete burn down to the floor, including fenders, hood, doors, and rooftop. No one was hurt, thankfully, but the truck is a complete write off, and it caught the side of their house on fire as well. The fire department was quick to get the house out, but the truck was gone in a matter of 15 minutes. To all those affected, don't use your block heater until you get the recall completed. They hadn't heard of the recall, so I wanted to put this out there for the sake of maybe saving someones life or property. Here is the link from Ford. Cheers.
