Brought my company truck in for oil service signed a contract with them for oil service and tire rotation everything went good 3000 Miles later brought it in for a second oil change and tire rotation then had to pay $380 for warped lug nuts now the studs were fine only the lug nuts are warped I am not sure the lug nuts were the Warped part of this transaction my point being they took a tires off 3000 miles ago the lug nuts won't work then if the lug warps are warped after 3000 miles it would be due to over-tightening that they did they didn't want to talk about this I tried to talk to my service advisor but she was no help
