I am disappointed with GM for first time ever. I had a 01 that I got 350,000 miles on it and it had all original parts. Then I buy a 08 and I have oil leaks four wheel drive light on my engine runs rough and my air bag light is on. I don't get it and trust me I just saw a website with the same complaints about what I have when is GM going to say oh [xxx] we have issues with this year maybe we should do something about it. If nothing comes about this I will be going Ford and tell GM to pack sand I have driven GM my whole life and would like to stay but I have owned this truck for only a year and hoping GMC opens there eyes.

Cylinder 4 misfire code which lead dealer to diagnose a bad lifter with cam damage, new piston rings needed, entire engine needed to be replaced. Cost $7,000 + afm contributed to problem in this model year per service department. Truck never hauled, or plowed with. Regular oil changes and maintenance done on time for entire ownership.

I was driving down the interstate and check engine light came on, digital dash stated "power reduced" + "exhaust filter requires cleaning", and speed dropped to no more than 45mph. = = after a few minutes, operation was back to normal. = = this issue has continued and seems to be getting worse whether pulling a trailer or not; flat or hills makes no difference. = = took the Chevy dealer in terre haute, in (spent hundreds of dollars) and local dealer in clinton twp., mi and they could not correct this dangerous performance issue. = = this problem should be a recall as I've it will cost me approx. $3000 to correct this "exhaust filter" problem / issue (which is really caused by the federal congress mandating through legislation about nothing they know about)...
