While driving, I noticed smoke coming from the front of the vehicle. Within moments, flames appeared in the engine area and spread quickly, causing severe damage to the front portion of the car including the engine, electrical system, and body. No warning lamps, error messages, or unusual behavior were observed prior to the incident. The fire started suddenly without any indication of mechanical or electrical issues. My safety and the safety of others nearby were put at risk as the fire escalated rapidly. The problem has not been reproduced or inspected by the manufacturer or dealer yet, but the vehicle was completely disabled and is no longer operable due to the fire damage. Cause of the fire is UNKNOWN at this time.
