I have a brand new 2010 honda civic gx ( natural gas vehicle) i purchased the car less than one month ago and have only driven the vehicle for the last week. i've been noticing the smell of natural gas and returned the vehicle to the honda dealer. the dealer instructed me that the vehicle has a substantial leak coming from the pipes between the tank and exterior. honda refuses to pay for the entire new tank and assembles and have opted to try and add new "o" rings. honda does not seem very confident in the prescribed measures from honda corporate and also don't seem very confident in repairing these types of vehicles. i'm very worried about the safety of these vehicles and would like to see if its an on going problem. these things can blow up if you have a leak of any kind. thank god the car was parked out side and not in the garage by the dryer and water heater. *tr
