Thanks for the response from you and the others. I needed to know if this was true through the line or if it were just mine. If this was just a characteristic of all of them, I was not going to pursue warranty. Now I will.

I live in New England, so have not had a chance to use the a/c yet. Haven't noticed the blower problem with the heating system though. Also have not noticed a transmission whine in first gear.

Posting in all caps is very hard to read. In fact, most people ignore messages in all caps, so I would be surprised if you get many answers.
 
My 2009 CTS climate control fan runs fast until the car approaches the set temp. Then the fan slows.

09 CTS - I finally found the fix for (my) creaky driver's seat. I used leather conditioner on the leather surface that mates with the vinyl trim around the perimeter of the seat & seat back - and WD-40 on the bottom vinyl seat trim "vertical seam" where the two front sections are joined together. No more creaking.
 
Good luck

OK, sorry for the delay..
 
I tried the 60 mph test. The average mpg did say 18 to 21 mpg traveling at aprx 60 mph on a flat road. OK, well, Hmmm? I have not had a long trip with the CTS09 yet doing primary highway driving. This will be my final test.
 
With about 40 miles of straight highway driving the best I have been able to get is 13.3 MPG average on a tank .(203 miles to a tank of gas - 15.25 gals)
 
I live in the Boston area and if you've driven here, you know it can be pretty much stop and go driving. Since I have bought the car I have calculated my average mpg for a tank to be from a low of 10.9 to high of 13.3 mpg.
 
Well what to I do now. Live with it?
My wife drives a 02 Jeep Cherokee Larado and appears to get the same or better city mileage. It appears other CTS owners are getting better mileage, so I just want to make sure I didn't get a .
 
The sticker lists 17 MPG city. Let's say I get 12.4 MPG (conservative driving). Is this difference typical?.
 
Is there anything I can suggest for the dealer to check?
 
Do Escalade driver's get 5 MPG?
 
I think the car is really sharp, I'm just a little bummed that it seems I bought a gas hog. ;(

Thanks for the advice. I'll give it a try at the first opportunity when the weather warms up a bit. I was seriously starting to think I was nuts, because no one else seemed to have the creaky seat issue.

Winter is really hard on gas mileage, mostly because engines rarely get a chance to warm up (and that means the oil, not the coolant) completely. I drove a car in Alberta for awhile that had an oil temperature gauge, and it can take an hour or more to get the oil to a stable temperature when it's cold out, and even at that, the oil temp is lower than when the air temp is higher, as in the summer. Add to that the fact that "winter-blend" fuels rarely do anything positive for MPG.
 
I've done a fair amount of long-distance driving out here in the wide-open west and watching the average MPG number continue to go up for an hour or two on long flat stretches in Nevada, has be convinced that getting too worked up over poor gas mileage in the winter where it gets really cold is not a good plan.
 
See what happens next summer on a long trip.
