Christmas toy on fire

I never imagined a toy remote controlled car could catch fire.  It only took four AA batteries and a tiny circuit board.  Flames burned through the windshield and were shooting several inches in the air!  It was not a nice Christmas surprise for our 4 year old nephew.

We were lucky there were people around when it happened.  My sister in law is going to report this on Monday.  I wonder if there have been other incidents and if they will recall the toy.
