THE CAR HAS A STRONG GAS SMELL THAT HAS A KNOW PROBLEM THAT HAPPENS WHEN TANK IS OVER HALF FULL. GM ISSUED A SPECIAL COVERAGE ADJUSTMENT 15682 PRIMARY TANK MODULE FLANGE FUEL AND VAPOR LEAK IN JULY 2016. BUT MANY OF US AS SECOND OWNERS DID NOT RECEIVE THE LETTER TO TAKE CAR BACK WHILE STILL UNDER WARRANTY, THE CAR HAS SMELL IS SO STRONG CANNOT PARK THE CAR IN GARAGE AND CAN SMELL WHEN IT OUTSIDE. I WOULD BELIEVE THERE COULD BE A RISK OF FIRE IF CAR WAS IN A SMALL ENCLOSED SPACE AND A SOURCE OF IGNITION WAS PRESENT. THIS SHOULD HAVE BEEN A FULL RECALL BASED ON A GAS VAPOR LEAK NOT JUST A SERVICE ADJUSTMENT. I HAVE TRIED TO WORK WITH GM ON THIS BUT THEY CLAIM ITS TO LATE EVEN THOUGH THEY ISSUED A 3RD REVISION OF THE ADJUSTMENT IN JULY 2017. TO ME FOR A KNOWN FUEL VAPOR LEAK PROBLEM THERE SHOULD BE NO EXPIRATION LIKE A RECALL

AFTER FILLING THE GAS TANK THERE IS A STRONG GASOLINE ODOR IN THE CAR. I FIRST STARTED NOTICING THIS MID-YEAR THIS YEAR (2019). AFTER SEVERAL DAYS, THE ODOR IS LESS. IF THE CAR SITS FOR A TIME WITH MORE THAN 3/4 FULL TANK, THE ODOR IS QUITE NOTICEABLE WHEN YOU GET IN THE CAR.

WHILE DRIVING ON HIGHWAY IN 5TH GEAR #5 EXHAUST VALVE DROPPED INTO THE CYLINDER GOING THROUGH THE PISTON AND CAUSING CONNECTING ROD TO GO THROUGH SIDE OF THE BLOCK. ENGINE SEIZED AND CAUSED THE CAR TO GO INTO A 65 MPH SPIN. LUCKILY THIS OCCURRED LATE AT NIGHT ON A OPEN 4 LANE HIGHWAY WITH LITTLE TRAFFIC. I NEARLY CLIPPED AN ONCOMING PICKUP TRUCK BUT SQUEAKED BY HIM. THE CAR HAD 32,000 MILES ON IT BUT OUT OF WARRANTY BECAUSE OF THE YEARS. TOTAL COST FOR THIS LS7 REPLACEMENT COST ME 18,000 OUT OF POCKET. I HARDLY EVEN DRIVE THE CAR BECAUSE I'M AFRAID OF IT HAPPENING AGAIN. I'M RELUCTANT TO SELL IT BECAUSE OF THE VALVE ISSUE HAPPENING TO POTENTIAL BUYER AND THEM COMING AFTER ME FOR THE FAILURE. GM NEEDS TO CORRECT THIS PROBLEM BEFORE SOMEONE GETS KILLED LIKE I COULD HAVE BEEN THAT NIGHT.
