I have a 2015 Tuscany and received the recall for the wipers. I could wiggle the driver's side quite a bit so decided to attack it myself. You can gain access to a allen screw thru the pop off plastic cover on the wiper shaft. Tightening the allen screw moves a wedge shaped part to more firmly hold the wiper to the shaft. I decided to position the blades to more evenly wipe the windshield while I was at it. Yep, a few minutes is all it takes.
