When I inserted the key to start the car, the battery (located in the trunk) exploded. It sounded like a gun shot inside the car, the battery was blown open at both ends and the battery fluid was thrown around the trunk cavity where the spare tire is also housed. A service tech advised me that a spark was necessary to ignite the sulfuric gas leaking from the battery. No one has been able to identify the source of the spark.
