I recently bought a 2008 Honda on January 2010 and I have driven it for 6 months. On January 18th the weather was cold . there was a crack from the drivers side to the passengers side there was no external impact on the inside of the car and the Toronto Honda dealership refused to take care of the damages.they said it was an external impact

this is absolutely ridiculous... I know that i was not in any type of car accident so i don't understand how this could have happened
