I had my brake pads inspected and replaced with Richards Auto Repair on 9/28/2020. Last week(on 3/24/2022) when I went to another shop for tire rotation and oil change, I was told that they couldn't do the tire rotation because of defective lug nuts(Later I found that the front passenger side lug studs were broken too). As Richards Auto Repair was the last shop to take my wheels off, so I went to them(on 3/31/2022) and asked if they can fix it for me. They denied breaking it and wouldn't fix it for free.
Why do I think they broke the lug nuts and studs? I remembered when they finished replacing the brake pads, the technician walk me through the car and told me that they caused some small damage on the lug nuts cap and it should be fine. I was not very happy but I thought it was just cosmetic and I didn't say anything at that time. I also did some research online and it seems that "The most common cause of a bad or failing wheel stud is due to improper installation by tire service technicians, over torquing of lug nuts, or lug nuts that are not tight enough." THEY WERE THE LAST SHOP TO TAKE OFF MY WHEELS and I never touched OR had anyone else touched the wheels.
I couldn't prove that it is their fault for sure. But the experience is unpleasant and I decided to go to another shop for repairing. It was not cheap, it cost me $448.37 for replacing the lug nuts and studs.
