“On 12/4/23, at 6:37 am PST, we initiated remote start via the key fob. At 6:40 am pst, a flash and fire erupted from under the hood of the truck. We immediately worked to control the fire using extinguishers and garden hoses until the fire department arrived a few minutes later. They worked to put the fire out that engulfed the engine compartment and then worked to get the hood open to finish putting the fire out. The fire didn’t fully go out until the battery cables were cut.”
