2011 Chevrolet Volt Suspension Problems

THIS PROBLEM APPEARS TO BE A SAFETY ISSUE THAT I'M CONCERNED MAY IMPACT OTHER VOLTS. HERE'S THE BACKGROUND. ON SUNDAY AFTERNOON, I WAS PULLING INTO MY GARAGE AT A VERY SLOW RATE AND GOT HALFWAY THROUGH WHEN I HEARD A LOUD 'CRUNCHING' SOUND. I GOT OUT WONDERING WHAT THE THE NOISE WAS AND SAW THAT THE FRONT DRIVER'S SIDE OF THE CAR DOWN AND DIRECTLY SITTING ON THE TIRE. THE CONTROL ARM OR STRUT OR WHATEVER YOU CALL IT HAD SEEMINGLY COLLAPSED. LOOKING MORE CLOSELY, IT LOOKED LIKE THE WHEEL HAD PRACTICALLY COME OFF. GREASE WAS DRIPPING ONTO THE DRIVEWAY FROM UNDERNEATH. THE DEALER HAS NOW REPAIRED THE PROBLEM AND CLAIMS IT WAS A BAD BOLT, HOWEVER I AM NOT CONFIDENT THAT SUCH A MAJOR MANUFACTURING FLAW CAN BE SO EASILY DISMISSED. *TR
