Well I picked up my Denali today from the dealer after my truck wouldn't start up last weekend. They had to replace my starter and my battery. All covered through warranty though so no biggie.
Also, I am getting my BOSE amp replaced because there is a short in it causing engine noise or feedback in the rear speakers.
Last Friday I had to buy some new tires. I opted for the Kumho Road Venture APT KL51 (245/65/17). They were $109 each not bad and they have good ratings on
TireRack.com. They are much better tires than the stock Michelin's. I hated those tires...
