We tow a 2012 Sonic (non-turbo), auto trans. It addresses "towing behind a motorhome" very specifically in the manual. Pull 1 fuse, turn the key to the 1st position, make sure in neutral and start the motor for a few minutes every fuel stop. I'm surprised that the turbo would make a difference but maybe it does. There is 1 model with different performance gearing that can not be towed so maybe that goes with the turbo? Its great to tow and only about 2700 lbs.
