While driving down the highway, my 2022 Ford F-150 Tremor randomly caught on fire. I was driving down the highway and was flagged down by other drivers to let me know the bottom of the truck was on fire. I pulled over and luckily someone had a fire extinguisher and we were able to get the fire under control. The fire department was also called and they also helped put out the fire after their arrival. The truck has always been serviced at a Ford dealer and had gone in for an oil change less than 350 miles prior to the truck catching fire.
