I did not take my 2017 C2 to the dealer for the suspected front strut mounts leaking. Have driven the car approximately 500 miles since I made that post. The car drives and handles as it should. I think a technician may have used a spray lubricant around the mounts during a routine service which was done before I purchased the car. I've had the front wheels off for cleaning and examined the front struts closely. No indication of leakage what so ever. Unless you see or feel something unusal in the front end when driving, I'd mention it to the technician on your next scheduled service. Otherwise, drive on.
