Ignition problems of the 2006 Chrysler Town & Country

Prior to this incident, there were no issues with the vehicle. No service lights were on and the vehicle seemed to be operating normally. At 11:00 pm on the night of the incident, I looked out our window and saw our van on fire. The fire was located in the front of the vehicle, primarily on the passenger side dashboard. The windshield and the passenger side window had been blown out as a result of the fire. The fire department responded and put out the fire. The vehicle was damaged beyond repair and is a complete loss. The fire fighters on the scene looked for signs of arson and indicated that there was no evidence of arson and no accelerate was noted or smelled. The report we received from the fire department indicated that the cause of ignition was failure of equipment or heat source, the heat source was electrical arcing, the item first ignited was electrical wire, cable insulation and the type of material first ignited was plastic. It also indicated that the factors contributing to ignition were mechanical failure, malfunction. The car was towed to the nearest dealership, which happened to be where we purchased the car five months earlier. The dealership refused to provide a loaner car even though our vehicle in under warranty through 36,000 miles. It currently has approximately 29,000 miles. The event remains under investigation and the dealership has indicated they believe we should file a claim with our insurance company. We have refused to do this as it is our belief that this issue occurred due to a defect within the vehicle and it should be covered by the factory warranty.
