Yeah same here. Had my 09 CTS since Jan and haven't even thought about worrying about my mileage yet. I'll check it about 10K miles...loving the car thus far though...got it just before the red tag sale ended....

climate control by joey245

I just bought a 09 cts a month ago. i live in south fl. and when the car sits in the hot sun the climate control fan only comes up to about 3/4 speed with the temp control set at 70 degrees. if I lower it to 60 deg or put the fan on high manually it works fine.
I had a 05 cts and have had climate control in cars since 1988 and when the car was hot inside the fan would come up to full speed until the car began to cool down.
I had the car back to cadillac and they are telling me that the factory says this is normal in the 0908 and 09 cts.
I do not buy that. has any one else experienced this and if so what was the fix.
as for wind noiuse in the sun roof,there is none when it is closed and the gas mileage on highway driving is great. over 30 mpg at 75 mph. local is about 20 mpg.
I had a 05 cts with an aftermarket sun roof and that always had wind noise and they could not stop it.

Your 27.6 is good highway MPG. I am wonderig if there is anything in common between those getting good MPG and not good MPG highway?
 
Do you have the base suspension? Sport Suspension 18" wheels? Or the 18" Summer tire suspension? AWD?
 
I am thinking that possibly AWD or Limited Slip is causing the lower MPG reports from some?

AWD is a bit tougher on the MPG....I have a non-DI FE2 suspension 09 CTS RWD, I average 24 combined....and 28-30 MPG on the highway depending on the hills......overall very pleased with the CTS.....4 months old...and just rolled 10K

Anyone experiencing steering wheel vibration above 60 mph with the 2009 CTS? All attempts to fix the problem haven't worked.

That would be great if they have a solution. Did they indicate the source of the problem and what types of parts were ordered?
 
Please keep us posted!

vibration over 40 mph by joey245
Feb 19, 2009 (7:52 am)

i kept getting a vibrating feeling in my ears when i got over 40 mph. i have a 2009 cts,1000 miles on it.
i thought i was nuts and when i mentioned it to my service writer,his reply was we know all about it. they ordered a rear differential insulation kit and re aligned the differential and now all its ok.
i posted the following question earlier and have not had any response.
when my car sits in the hot sun and i start it up the climate control blower only comes up to a little more then half speed. i have had climate control in cars since 1988 including a 2005 cts and when the car was hot inside the fan speed would come up to maximum, until the car started to cool down.
the only way i can get the fan to come up on high speed is to lower the temp to 60 degrees or bring the speed up manually.
general motors tech has told my dealer that this is the way it works in the 2008 and 2009 cts.
i think they have a manufacturing defect. if any one else is experiencing this problem,please let me know. if it works properly,i would also appreciate hearing from you.
