NHTSA Complaint #11468324 — 2017 FORD ESCAPE

We took our car in for oil change and tire rotation, we were informed by service manager tires couldn't be rotated because lug nuts couldn't be removed, did we want lug nuts replaced which we did, after done ask why did the lug nuts fail on a car with less than 21000 miles was told it was a split lug nut poorly designed and when seal breaks and swells they can't be removed. In my mind this is a safety issue as we wouldn't have been able to change a flat tire if the service department couldn't change and we wouldn't have known this issue existed had we not had the car in for oil change and tire rotation. So if we had had a tire issue on the highway we would not been about to change our tire, leaving us stuck on the road. I don't have a clue the number of cars on the road with lug nuts that couldn't be removed. I believe Ford should replace all these poorly designed lug nuts
