I bought an 08 in Jan. I've put almost 15,000 miles on it, Belts would squeek on start up in the morning, took it to the dealer, said this was common problem from the factory, replaced with new belt. The next morning!! The belts still sqeek... Took it back to service Dept. , The belt was starting to shred? Service Mgr., said they used a laser to see if pullys are alligned, said everything was in place, thought it was a bad belt from factory.....:sign0023: Put a new belt on and sent me on my way...... To my suprise it didn't sqeek for about a month...Then there it was in morning on start up!!!:grrrrrr: So once again back to the dealer... Service Mgr., said pullys where out of allignment, realligned pullys and put a new belt on, sent me on my way! WOW one more month went by and guess what........SQUEEEEEK,SQUEEEEK,SQUEEEEK......... WTF...........Come on!!!! :grrrrrr: Also my vents were rattling, when blower was on high......Factory Recall, that was fixed for now! Any one else having the same issue with their 08 Silverado 1500 Z71?????
