We own a 2013 Traverse and have towed it about 6000 miles over the past year - no issues. You do need to follow the instructions in the owners manual and not exceed 65 MPH as directed in the owners manual.
Have a Blue Ox base plate self installed with no issues. Also added a Ready Brake because of the weight of the Traverse, works very well. Lost about 1 MPG when towing.
Found a lot helpful information on some of the Traverse forums on the web. That would be another excellent source of information.
Hope this helps.
