One problem related to carrier/rack has been reported for the 2014 Chevrolet Silverado. The most recently reported issues are listed below.
Was driving to physical therapy. Pulled up to a stop light and "stabilitrack failure" poped up. Was pulling into the doctors office not 8 min l8r came up again but this time steering wheel locked up then un locked then locked up multiple times while I was trying to pull into a parking space. Thankfully I was going at an extremely low speed and I could control the vehicle between it locking and unlocking. When I left the doctors office I noticed my settings reset. Ex dashboard display showed the radio station instead of the fuel economy. I simply changed it and noticed the computer erased my previous fuel economy. I'm assuming theirs some malfunction between the computer and these systems. And from the looks of it my vehicle isn't the only vehicle with this issue. Now my check engine light is on and I'll be taking this back to the dealer and it will be fixed and never happen again or I won't purchase another gm vehicle.
