Driveshaft recalls All years
What to check: Make sure the driveshaft recalls were done.
NHTSA lists a recall for driveshaft slip joints left without grease on some 2015 and 2016 cars, and one for the driveshaft-to-flange joint, which can fail and lose drive, on 2016 and 2017 cars including the GTS.
