We're 3 weeks and about 1700 miles in to our new 2015 LTZ 4wd Suburban. I'm starting to notice some odd kick back and "sticking" as the steering moves through turns, expecially at a little higher speeds like 30mph or so. I'm not sure if that's the new normal for the electric system, or does something sound like it's defective? It does not feel unsafe at all, just not smooth and like it has hiccups as it progresses through the turn. Thoughts?

 

Take the car back. It isn't normal. Other people including myself has had this problem. You have to get your whole steering column replaced and then hope it doesn't lock up on you. Mine was clicking and knocking. Then it took forever to fix because Chevy had a hard time fixing it due to,safety issue. I get the car back and a few days later I am pulling out of parking space and steering column lock displays on dash, several times. I had to brake and turn car off and re start to get it to drive and steer. Good luck.
