There are 2 owner-reported tires & wheels complaints for the 2016 Lincoln MKCin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Had a flat tire. Tire could not be removed. The tin caps on the lug nuts have swelled. The lug nut wrench that Ford provided would not fit over the lug nuts. The AAA service that came out to help, also could not remove the lug nuts. I don't know how I will be able to get the car inspected. I also don't know how I will be able to have the brakes services or replaced. A very serious potential catastrophe. The equipment that Ford includes, with a car, should be able to do its job. I along with many other people are left with a serious problem. This is a problem Ford is aware of and will do nothing. Many Ford owners have this problem.
Swollen lug nuts prevent use of correct wrench or supplied wrench to remove wheel. This means inability to change a tire. Needs to be warranted for lug nuts that do not swell.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
