This is hard to describe but when I turn the steering wheel tightly when in parking lot, as I move car forward front tires act similar to when 4 wheel drive is engaged on dry conditions in a truck. Does not happen at speed but makes noise and get wired thumping/vibration in steering wheel. Dealer told me it is normal based on the tires being sticky and the way the front suspension is set up. I don't think this is normal and don't understand how this can happen since both front tires are completely independent of each other. Has anyone else experienced anything wired when making turns in parking lots etc?

If the noise is only coming from the front that is a common experience on this car. If you are getting noise from the rear as well there might be a e-diff issue at play as well.

The GM comment in the Owner’s Manual says it’s normal (page 10-62) but those few words do not describe it or if you have a passenger - will they accept it! Many say it is the lack of Ackerman steering built into the C7. It is more than that! In fact some have said it goes away when they switched to all-season tires. I have had my Z51 (it’s worse with it) since the 1st week in October. After researching possible reasons I made a 4 page doc with pictures that show what Ackerman is, that the C7 has a 2 foot tighter turning radius than the C6 and the big item, tires and slip angle.
Good to have when you’re discussing with your friends to have them stop laughing! You can get a free PDF at: netwelding.com/reports_vette_info.htm
There is a simple solution, especially when you have passengers, don’t turn the wheel as sharp, when moving slowly and when the tires are cold!

Good write up but there's another option,

Show them nothing but tail lights on the twistiest, most technical road you can find then see if they are still laughing...........

I've experienced this to varying degrees with a number of cars over the years and on some cars that have never shown the issue simply changing to some of the latest hyper performance tires will cause the chatter. I'm really glad the engineers didn't succumb to the typical response and engineer the chatter out because the net result wouldn't be the shorter turning radius AND +1G lateral acceleration. A classic example of you can't have your cake and eat it too.

In a few years they will fix this by having a variable turning angle between the tires. At low speed (<10 MPH) it will give the inside tire more angle, and at higher speeds it will perform exactly as it does now.

If they can pull off cylinder deactivation and all of the other goodies they have done, they will easily be able to do this.

Thanks to all that replied. Feel better knowing this is not something unique to my car. But still don't like it! Willing to take this based on the rest of the cars benefits and performance.

Explained in earlier posts. Car set up is proper. Don't turn wheel all the way

Ref this, I drove all the way fr Florida to Bowling Green. When I got here it was raining. Upon trying to pull into a parking space, the front tires started to skip real bad. It seemed that the rain makes it worse. Is this normal too or should I be worried that something in steering is bad..

A wet surface makes it worse. Had my C7 for over a year. When at full lock pulling out of my garage this summer felt nothing. At 55F starting to feel it already. When it's 40 F and below I turn about 1/2 turn less than full lock and make a K turn.

My 2011 CTS-V coupe did the same thing
