Active fuel management shifts from 8 to 4 cyl whenever causing a vibration and rumble noise. Had it to the dealer numerous times, they couldn't fix it, had factory engineer in on it, he couldn't fix it. Chevy main headquarters tried to reset the computer, didn't work, they said that was the way it's supposed to work, BS. Read online many complaints about this.
Had the front end aligned, wheels rebalanced, nothing. Just got a 2015 and thought by now they would have fixed it, no such luck. They need to junk this 8 to 4 shift crap except it shows it is supposed to get better mileage for the Govt specs. The mileage is about as good as I got with my 2007 Suburban. They don't want to spend the money to correct this, they just blow off everybody that complains.
