Has anyone had this happen to them? When my Armada is cold the oil pressure guage moves all the way to the right maxed out. After a few minutes it returns to the middle position. I have checked the oil level and it is normal. The car only has 2000 miles on it and i have yet to take it in for the first service. Also there is a TSB for the rattle coming from the DVD player for the model with the sunroof. But i don't have a sunroof but a sure got a rattle.
