Problems with 2007 GMC Yukon XL 1500 ENGINE AND ENGINE COOLING

1. no leading events 2. "engine power diminished" error, vehicle loses power, traction control and stabiltrak. vehicle cannot maintain speed. occurred 3-4 times a week and then reset after car was turned off and restarted after 15 minutes. disruptive and dangerous on highways and in less secure areas when driver had to stop. 3. the dealer replaced the throttle body and throttle body connector. part was on national back order because of failures across gm & chevrolet models. neither the dealer or gm will acknowledge part failures. *tr

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. *tr
