Natural gas explosions are nothing to sneeze at. Especially if sneezing is what prompts the explosion.
“About 6,000 Volkswagen Touran vehicles are recalled worldwide to replace gas tanks that can explode due to corrosion. The 2006-2009 Touran minivans have front compressed natural gas bottles that can burst.”
VW says the minivans should be driven using only gasoline until they can be repaired. Makes sense.
