Re: Lots of noise on start up?
I have noticed the abnormal roar too. But like your dealer said it only lasts a couple of hundred yards. Thing is, it doesn't do it on every start up -- only occasionaly.

You should be doing much better than that! Around 300 with 35's and 350 with33's
Get it checked.

Re: Lots of noise on start up?
your gas mileage is about right one, mine is stock, and i get about 150-170 miles out of the first half of the tank, and overall i get about 280 miles out of each tank, i fill about 19 gallons each time so do the math, but its not hurting your gas mileage. Mine is also a bit louder when i first start it up in the morning, but goes away by the time i get down the street. Take it to the dealer and tell them to look at it, not just assume, if your car is under warranty, you wont pay a dime.

Re: Lots of noise on start up?
My loudest noise is the brake grinding... guess i'm lucky...
using the gauge i feel good when i get 200 miles on the 1st half and another 100 miles on the second...don't understand why the gas gauges are not more accurate. 15 MPG is a good overall average for me. Highway only i get 19 to 20 mpg...
wherever possible i put on the cruise control and try and keep my highway speed under 65 mph
BTW...i use the A/C over 99% of the time

Re: Lots of noise on start up?
There was a thread some time ago about the tentioner pully making noise at start up ? I never had that problem  .
I have been living with the brake noise(normal says hummer rep  ) since 2005 GRRrrr.( a little brake lube at rotation is a temporary fix.)
My wife drives kinda hard 15 1/2 around town 14 1/2 in the winter using auto start. 75MPH on Hwy im getting about 18 on a trip a little more or less depending on speed.
Pulling a 4,000 camper about 12 1/2 to 13 MPG at 60/65 depending on hills.if I run 65 to 70 I wont get more then 12.
