“Our vehicle caught fire. My wife and I had just gotten off of the interstate when we started to smell an odd smell. We pulled into a hotel parking lot where we started to see smoke coming from the front of the vehicle. I stopped the vehicle in a hotel driveway, put the vehicle in park. We got out of the vehicle and saw flames underneath the vehicle. We called 911 and hotel staff tried to extinguish the fire but it continued to grow. The fire dept. Arrived and put out the fire. Photos are attached.”
