The truck I purchased has a max towing package that is supposed to safely tow 10,600# in crew cab configuration. I have a 28' pace daytona trailer that weighs under 8,000# as I tow it. At approximately 50 mph, the truck has a very severe sway issue. It is frightening to drive as the trailer starts shifting the rear of the truck back and forth. I have not had an accident with the truck as yet, but I feel the situation is very dangerous. I have contacted Chevrolet customer service in Michigan to ask for assistance with this issue. They say they have no information that can help solve my problem. I was instructed to bring the truck and trailer to lone star Chevrolet in houston where I purchased the truck. Several visits there and talking to several service people has yielded no help. I was told that the truck can't pull a trailer of that physical size. Oddly enough, the 2012 model truck advertises a new sway control feature. This 2013 brochure ever depicts a scene of the trailer swaying as mine does, with a box type trailer in the add. Since Chevrolet claims it has no history of this being an issue, I felt that I should notify someone of this unsafe situation with this particular vehicle. Thanks for allowing me to share my problem with someone who might research this issue and try to prevent a serious accident.

I was traveling on a divided highway and approaching a slow moving truck in the right lane ahead of me. There was another truck behind me in my lane. I moved to the left lane to pass the slow truck. Just after I began the pass my pickup slowed quickly and began flashing error messages: Stability control disabled, engine power reduced & service stabilitrak. The truck behind me had moved up close and followed me around the slow moving truck. I was unable to accelerate and continued slowing quickly. I had just enough room to swerve in behind the slow truck as my speed fell below its speed. The truck behind me narrowly avoided a rear impact with my truck, which, I believe, would have been catastrophic. I pulled to the right and tried to speed up. About 40 mph was all my truck would do. I stopped and got out the manual. It said to reset the stabilitrak, turn the vehicle off for 30 seconds. I did that and the truck seemed to functioned normally, at least as far as engine power. I still had traction control & stabilitrak error messages and the service engine light was on. I was able to return 40 miles to my home town with no further incidents. I was able to get my truck into the Chevy dealer on the 30th. The service rep recognized my description immediately as a "throttle sensor" failure. It was repaired under warranty. There have been no further incidents. My concerns are dual: First, only luck and years of emergency vehicle operation training enabled me to avoid being hit from behind by the following truck when my truck unexpectedly and without warning lost power. An impact would have likely be life threatening considering the speed and proximity of two trucks. Second, subsequently, I have found multiple internet reports of this issue going back several model years and my service paper work indicates a GM service bulletin for it exists.
