CO_2014LTZ

I waited a few months to respond on this forum, but I had seat movement also a few months ago. I told the dealer, and they ordered the necessary parts which took about 3 to 4 weeks to arrive. The seat was repaired August 2014, and since that time I have not had anymore seat movement. During my initial visit to the dealer, I did provide them a copy of the bulletin I found on this site. I guess I was lucky (so far) with the seat repair.

I too have this problem, 5500 miles. I have not spoken to my dealership yet, but will do this soon. Odd that I can trace this forum thread way back to last year and GM has not been able to fix this automatically for their 2014 vehicles built this year.
