Tesla (TSLA - Get Report) said Monday it has sent a team of investigators to take a closer look at a parked Model S sedan that appears to have self-combusted in a ball of flames.

In a video, time stamped Sunday evening and widely shared on China's Twitter-like Weibo, a first-generation Model S sedan parked in a Shanghai garage appears to begin to emit smoke, and seconds later bursts into flames.

The video began circulating Sunday night (April 21), and posts with the hashtag #Tesla self-ignites" or 特斯拉自燃, had drawn nearly 18 million views as of early Monday.
