Have a GMC Sierra SLE bought brand new in 2011. Vehicle has always been serviced by GMC dealerships. Shortly after the 3 year bumper to bumper warranty was over, got a $400 bill for a new seat belt retractor. Thank you. Now, 2 years later when the 5 year power train warranty is over (vehicle only has 65,000 miles on it) welcome to an engine rebuild! Vehicle has been to dealership 4 times over the past few months. Each time it was an emission related problem. Relocation kit for evap system, charcoal canister replacement, and Im not sure what caused this problem were the last few visits. This time, when the power train warranty expired (4 weeks ago), oil fouled spark plugs. New pistons and rings are required. Service advisor said this is common when vehicle switches between 8 cylinders and 4 cylinders ecomony mode.. I have been a loyal GMC buyer, but now I think FORD and DODGE will be my next vehicles of choice. GMC you unfortunately are loosing a customer and my experience will be told to other car purchasers for their reality check.
