Road irregularity problems with new GS
Just posted this inquirery in the tech section of this forum and someone suggested I post it here for more response.
I have recently got a 2010 GS and am disappointed with the large amout of road irregularity steering problems it has. I just sold a 2005 that I put 70,000 miles on and had none of these problems through two sets of tires. Tire pressurs are right on at 29 cold. Car has less than 2000 miles and problem seems to be getting worst. Anybody else having this problem??

My 2009 had some handling issues which a 4 way alignment resolved and was covered under the factory warranty. Start there. Cheap insurance to save your expensive tires and it may fix the issues you are having.

Are you meaning the tires get caught in road grooves and cause the car to move right or left????That's a normal thing with big fat tires like we run.

The stock GY Supercar tires are your problem, they follow every groove and require constant course corrections. Tramlining is very common.
I solved the tramlining by buying General Exclaim UHP tires, i didn't touch the alignment on the car at all but the tramlining stopped instantly. I'm much happier with these tires compared to the OEM GY's.

Edit: need to say there is NOTHING wrong with your GS....it's mainly ALIGNMENT...if ya just bought it look up setting (camber/toe-in) to your liking take to dealer have them put those nymbers in and I promise that issue will be gone

"Groove tracking". Tractor trailers make grooves in the pavement, most passenger cars wheel widths are narrower than these grooves and steering is unaffected. What you have with these wide tires is the constant track of one of the front tires falling in this groove, then you correct, only to find the other side drops into the groove......then vise versa... its a common problem with high performance cars. Draw a line closer to the shoulder or center line....

Why is that not a surprise, coming from you?? 
To the OP. 8700 miles on my GS, including a 4000 mile road trip. Handles differently (and better) than my former C6, but nothing I worry about. Actually, my chief ride comfort critic, my wife, deemed the ride more than acceptable vs. previous Corvettes (including a narrow body "ordinary" C6). Realize your question regards steering and not ride, but I haven't noticed anything abnormal other than the sucker has fat tires and manages pavement differently.
You've received some good advice on things to check from others. Personally, I haven't had a problem.
Good Luck!

GM should sell the Grand Sport with a disclaimer about the "tracking" or "tramlining" due to the wide tires of the car. Right on the front windshield:
"Driver Caution: Due to the width of the tires on this vehicle, the driver will experience tramlining. The vehicle will have a tendency to follow the longitudinal ruts and/or grooves in the road causing greater driver fatigue."
Of course GM admitted to this and claims that the 2011 GS has new programming to help minimize this problem but apparently people are still having this problem.

I agree with those that recommend a complete alignment. Over the years, many have commented that the factory alignment leaves a lot to be desired. Mine needed re-alignment. I would try that first and check the results.

DRIVER CAUTION:
This Grand Sport is equipped with Goodyear Supercar tires that will wear out alarmingly fast.
That is considered normal.
Also it is recommended that you do not drive this Grand Sport equipped with these tires
on wet and or cold road surfaces.
Doing so could cause the tires under those conditions to loose grip with the road surface
and cause the driver to loose control of the vehicle.

Me either. The GS Wide Body handles WAAAAAAAAAAAAAAY better than my former narrow body. The GS continues to out sell the Base Coupe
