I receive too much information after the fact. I complained of my tires wearing and when questioned I was informed a tire rotation does not include balancing. Therefore the tires went 14,000 miles and were not balanced. I had previously taken my truck in with excessive wind noise.....after keeping my truck all day I was informed that it was acceptable noise level. The next day I took the truck to my local body shop and the guy corrected the problem in less that 5 minutes with a screwdriver.....he didn't even charge me. I did not purchase the extended warranty the dealer was pushing and I bought GM extended warranty so it looks like I will have the go to another tow when/if the truck needs repair. Not a satisfied customer.
