got a letter from my dealer last week stating that i had to bring in my truck to check something and it would take 1-2 hrs. stated it was not a recall but needed to be done. brought it in yesterday and was told that the factory had discovered that the freeze plugs were not properly inserted in certain vehicles with vin number between --- and ---. as it turned out i had to leave the truck all day since it couldn't be checked till it cooled down, the good news was that mine was ok and the better news was they gave me a hemi magnum to drive for the day- what a blast but now i have to buy one for my wife
