I need to replace the gas tank vent hose, or whatever you call it. Where is the best place to get one and how difficult is it to replace? I was also wondering if anyone with an 855 has experienced all the locks locking when the rear hatch is shut especially when the weather is cold. I once had my 2 year old locked inside while at the recycling center, keys in ignition, phone in car, not cool. It seems to be a completely random event, happens less than half the time.
