NHTSA Complaint #11674811 — 2018 FORD ECOSPORT

After reviewing the latest service and inspection report was informed that the lug nuts are swollen and need to be replaced at a cost of $195.00 USD. After inspecting the vehicle lug nuts myself the marks on the outside of the nut show the pattern from the use of a twelve point socket when a six point socket should have been used. I replaced 14 of the 16 lug nuts on this vehicle but was unable to get 2 of them off; one on the left rear and the other on the right rear wheel. This style of lug nut; ie. 2-piece is a safety hazard as the two remaining wheels cannot be easily changed by the owner in the event of a flat or other issue. The information from the dealership was not totally correct as I was told they other portion was alumninum when my testing shows it to be steel. They said that they swell due to corrorsion of which there was none. How do I trust they are giving their customers the correct information when I hear this. Subjectively, I believe the original damage was caused by the service staff using a twelve point socket instead of the correct 19mm six point socket. You can see the marks left on the lug nuts in the include image.
