Alignment Problems
I have owned my C7 for over a year now and can not get the alignment correct. The car has always pulled to the right, and its not a slow pull. The car will swich lanes in approx 5 secs. The dealer has aligned all 4 tires 3 times and they have replaced the front tires once. Has anyone else had this problem. Im such a perfectionist, and this drives me crazy. Any help or comments is greatly appreciated!

Sounds like you've ruled out alignment and tire issues, but you might want to try another alignment shop just to be sure.
Are the roads in your area highly crowned or damaged by heavy truck traffic? Does it pull right even in the left lane of a decent highway?
The C7 has electric power steering, so I wonder if something amiss with the sensors or calibration could cause this.

I have driven on roads all over Dallas/Ft. Worth and it always pulls to the right and never to the left. I have driven my wifes car and my 2015 GMC on the same roads, and they drive as straight as an arrow. So I know the roads are not the problem. Maybe it does have something to do with the power steering? The dealer is getting with GM for direction. Luckily the dealer has been great and not charged me one penny.

If alignment and tires don't fix it then it's a defective or miss calibrated steering rack. There have been a couple of instances where that's been the cause. Ask the dealer to recalibrate the steering, there should be a procedure for that in their Tech2 system. If that doesn't work have the problem escalated to GM.

If they're directional, they have to be taken off the wheels to be switched side to side. That's not worth the trouble if they've already been replaced with no change in symptoms. It's more likely something else.

Thanks for all the comments. I am taking it back to the dealer on Wednesday. And to answer your question, the dealer has tried swaping the tires and switching, but that didnt working either. I will suggest to them to align the steering. I will post the results!

There is a bulletin about this:

Zymurgy beat me to it, I saw that bulletin last year . Is it possible that in all your visits the dealer never checked for service bulletins and PI's?

Alignment Problems
I have the same issue-pulls to the right.
I took in to dealer for alignment and showed them the bulletin. They did alignment and charged me about $125. It didn't fix the issue.

unless you set up the cross caster way out of specs, it will pull right. I had mine aligned and it still goes right, but I did not have the cross caster put out of spec as per the bulletin, tire wear is more important, and the cross caster will cause tire wear. It is fine to me, as at least it takes you away from oncoming traffic, I do notice that when the road is crowned to the left I go straight or slightly left, just hyper sensitive to the crown on the road.

Sounds like they're pushing the wheel alignment to the limits (or slightly beyond) to compensate for something else being out-of-whack. I'd sure like to know what that something else is.
The tolerances achievable with modern manufacturing methods permit some manufacturers to produce cars with no provisions for adjusting caster or camber, leaving toe-in as the only available adjustment. These cars rarely have alignment problems as long as the bushings are in good shape and nothing gets damaged, and they don't pull to one side when going down the highway.
The fact that the bulletin specifically mentions pulling to the right as a symptom is odd. I'd bet they know what's REALLY wrong, but just don't want to pay for fixing it. So, the owner is going to pay for it with increased tire wear and/or reduced handling performance.
