Jan 2012 Steering grinds or is rough at low speeds. Dealer checked and said nothing is wrong but GMC created a file and will watch for others with this problem. Rear seat does not fold flat--appears stuck.Dealer lubed the lever and said I was not pulling the lever properly (give me a break). I tried several times at dealer and it worked fine. Got home and tried again and it did not work.
