WHEN I WENT TO TALK TO THEM AFTER FIXING THE VEHICLE THE SERVICE REPRESENTIVE PULLED ME TO THE SIDE AND TOLD ME HE THOUGHT THIS WAS A EXTREMELY DANGEROUS CONDITION AND DID NOT BELIEVE THE VEHICLE WAS SAFE TO DRIVE. HE ALSO LET ME KNOW THAT THERE IS A TSB ON THIS PROBLEM AND CHEVROLET IS AWARE OF THE PROBLEM (TSB DOCUMENT ID 1686251) . AFTER TALKING OVER THIS MATER WITH SEVERAL MECHANICS THEY ALL AGREED THIS WAS A EXTREMELY DANGEROUS PROBLEM AND COULD EASILY CAUSE INJURY AND / OR DEATH. WHAT IS AMAZING IS CHEVROLET IS AWARE OF THE PROBLEM AND FROM WHAT I CAN SEE THE NTSB IS ALSO AWARE OF THE PROBLEM AND NOTHING HAS BEEN DONE.
