'Day folks. Just became a member and thanks for the all info that I have learned while truck shopping. Thought I'd pass along personal experience to the other frustrated owners. My truck was built Aug/2013. Picked it up end of Dec. it was towed by the dealer 3 times in three days. They had it for a week. According to them and GM, a batch of starters did not have a seal cured properly, allowing moisture in. so, when it was cold and it was cold, minus 20 c, the starter would freeze. The cure was to remove the starter cook it in an oven to dry it out and then bake the starter to cure the seal. Have had no starter problems since. Hope this helps some.
