My 2007 Yukon denali with the new 6. 2 litre engine started leaking raw fuel onto my garage floor due to a defective fuel injector after driving 2 miles home from work. I noticed the smell as I exited the truck in my garage. I immediately coasted the truck out of the garage realizing I had an open flame 10 feet away from a gas water heater and a gas furnace. The same day I saw a blurb on the local news of a couple of house fires involving 2007 Yukons. I'm convinced this was probably the same scenario but I recognized the danger instead of closing the garage door and going into the house. Please look more into this issue. My profession is firefighting and I know this could have really gotten ugly if I had not noticed it.
