Graduate, how do you like your car after some time now?
I still really really like the car. It's tighter rattle-wise than my Accord was at the same miles, which is a big victory to my OCD ears. The V6 power will really surprise you when you aren't prepared for it; I'm still used to laying on the throttle from the 4-cyl on the highway; in the V6, just a part-throttle push will usually do the trick. I did a lot of in-town driving this weekend and averaged 24 (as many city miles as interstate, but of course much more time spent in city driving and Costco-style parking lots). On the interstate, at 70, the car will do 32 MPG in moderately hilly Alabama.
The quiet of the car at speed is most welcome with four people trying to converse on the interstate; hard to do in a Honda. The Honda was more fun to drive, without doubt, but the Sonata is definitely the better highway car. It also has a softer-throttle tip-in and more gentle brake modulation, making it the better car in heavy traffic, to me.

I have a 2009 Sonata GLS Auto 4 cyl. The car lurches forward with only minimal accelerator pressure. I don't really mind, but I think this may adversely impact my gas mileage as I am getting only 23 MPG with mostly highway driving. Does anyone notice this issue? I am wondering if dealer maintenance can correct this problem under warranty?

My guess is that it's not a mechanical problem--the car is functioning as designed. Frequently cars are set up to appear more powerful/responsive than they really are, through the design of the throttle system.

But 23 mpg on the highway is not acting as designed, under "normal" highway driving. Hyundaisonata, can you tell us about your highway driving? What speed? How long is the typical trip? What kind of weather? How many stops? How's traffic? Are tires inflated to spec? Does your gas have ethanol?
One way to check if the car is getting the fuel economy it should is to find a flat stretch of open highway with little traffic, so you can maintain a steady speed. This drive should be several miles. Then warm up the engine and as you start cruising at a fixed speed, reset the mpg meter. Keep the speed at the limit, and try to use a light foot on the pedal (or use cruise control). Be sure you are in 5th gear. If the speed limit is 55-60, you should easily hit the EPA highway rating for the car--actually you should exceed it. At 65-70, you should still be able to hit the EPA rating. Above 70, you should still get WELL over the 23 mpg you are getting now.
If you don't get results like that on this test, and the tire pressures are correct and weather is not real cold, I'd say there's something that needs to be checked by the dealer.

I bought a used 2009 Sonata GLS with 21k on it. Nice car but I notice wind noice, almost a whistle-like sound on the highway. Had a S-series Saturn 10 years ago that did the same thing. I was told it was air passing around the side view mirrors, don't know what the cause on the Sonata is.

Change your air flow from fresh to recirculate and let me know if it improves.

No change when the air is recirculating vs. open, it does seem to be coming from the side view mirrors though. Wish there was some way to get rid of it. What I find strange is that I did not come across this issue anywhere. I researched this car on Edmunds, Car and Driver, Motortrend, Consumer Reports etc. Never came across this issue, googled it after I noticed it on my car and came across it on this forum. Thanks for the suggestion though!
