1. The transmission shifts extremely rough from 1st to 2nd gear in parking lots at a slow speed and on normal highway or street driving and experiences the same thing while slowing down to stop 2. The engine has recently been having a awkward shake to it while in ideal after it has been running and warm 3. While backing up and turning the wheel, the front suspension will let out a loud clunk sound and the sound will return when turning the wheels back forward after putting it into drive.

I began to hear what sounded like loose rear suspension components about a year into owning the truck. I took it in for service and was advised that per the gm service bulletin, they re-torque the leaf spring bolts. It was fine for a couple of months, then the noise began again. It's now been to the dealer 4 times with 11 days out of service. The response continues to be, they've re-torqued the bolts to gm specs and nothing else they can do. It's very clear by the noise that can be heard, both while moving forward and backing in, something is not within specs. The truck is under warranty and I am a couple of months over on lemon law arbitration. Gm is doing nothing to address what could easily be a safety issue and I'm concerned that the bolts continually need to be re-torqued. I've taken to online forum searches to find that this is a common problem with a similar tap dance done by gm. It's shameful that consumers are buying a $40k to $70k truck and having these issues with no solutions being provided through the truck warranty. And when the warranty runs out, how expensive will this be? not to forget, dangerous. I am concerned that one day, the rear-end is going to come out from under my truck and hopefully it's not while on the highway with my daughter in the truck. My truck is used for my daily commute to and from work. It's well maintained, not abused and has under 20k miles. I've turned to bbb for help and was offered 2 years of oil changes by gm. Oil changes don't fix the problem!.

In only 600 miles the suspension was begining to feel like a buckboard, and if a good enough sized pot hole was run over trhe sound was so loud and there was a distinct bell gong rattle. The dealer said they didn't notice anything peculiar, but for a truck with 6000 miles only and 1 year, it felt 10 years old, this problem never went away, and infact got worse, much worse.
