My 2012 extended cab does the same thing. I had the dealer look at it and they tried adjusting the doors, but it didn't stop. If you apply silicone to the weather strips it will probably go away for a few days (mine does). There was a TSB from GM that addressed this on ealier model years, but it wasn't extended for 09-13. I bought the tape referenced in this TSB and need to install it.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
The above referenced TSB can help with certain noises, but most of the noises that are heard from these doors can only be cured by cleaning the door seals and applying a light silicon lubricant to the weatherstrips and have this done at every service.
I ordered a silicone lube made by GM just for the door weather strips, got it on ebay. Works well and really quiets the noise on the rough roads. It also keeps the doors from freezing up where the weather strip meets the top of the door. It has also worked wonders on my wife's kia
van, those dang sliding doors always freeze shut in the winter. The stuff tends to collect dust where the weather strips meet the metal but it is easily cleaned with a little silicone sprayed on a rag
While I have used the GM dielectric silicone grease, part number 12345579 on the weatherstripping, dielectric tuneup grease also works well and is available at most auto parts stores.
Thanks for the feedback. I have the 3M silicone lube sitting in my garage so i will give that a try and see how it works.
I will let you know what the end result is.
Thanks again for the info.
