Happened to my brand new…
Happened to my brand new 1999 Chevy Blazer while not towing. Tow truck driver said it was due to cold rolled steel being used vs hardened steel. Chevy Corp. said I was the only one in the nation that had lug nuts shear off, good by. No recall was ever announced. No egg shape holes on rim. It looked like they used pewter. After hearing that others had also experienced this with their Blazers, I never bought another Chevy or related product again. Never had it happen since.
