I know two people who are sucessfully towing MKX's and many who tow the MKT. There is a lot of conflicting information out there. I have been told by Lincoln that these cars are towable, and I've been told by dealers that they are not towable. The owners manual and Ford's 2016 towing guide say they are towable. Ford and Lincoln need to resolve the information crisis.
As for the Cadillac XT5, I am very upset that it is not towable as it looks like a great improvement over the SRX.
