I do occasionally look online to find out if any recalls have happened but no info can be found about them even discussing the issue. I do understand these trucks with the issues are older but I also believe ... Read More

  I actually have my 2010 GMC Sierra at the dealership now, although we have different issues with the truck it is also with the transmission and the dealer's mechanic drove it and noticed the problem.
