2012 BUICK VERANO Engine And Engine Cooling Problems

The contact owns a 2012 Buick Verano . The contact stated there was an abnormal odor of fuel entering through the vents. In addition, while driving, there was an abnormal very loud knocking noise. The contact noticed that there was oil or fuel leaking from the injection system. The TPMS warning light was illuminated. The vehicle was taken to the local dealer but it was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 120,000.

THE ENGINE OF THIS NEW 2012 BUICK VERANO STALLED FOUR TIMES. THE FIRST TIME WAS IN FREEWAY. THE SECOND TIME WAS IN FRONT OF A RED LIGHT. THE THIRD TIME WAS IN A LOCAL STREET AT ~35 MILES/HOUR. THE FOURTH TIME HAPPENED WHEN THE DEALER SERVICE DEPARTMENT WAS DRIVING IT. SIMILAR PROBLEM EVERY TIME: THE ENGINE SUDDENLY STALLED AND BECAME VERY ROUGH. THE CAR CANNOT GO FASTER THAN 10 MILES/HOUR FOR A MINUTE OR TWO AND THE ENGINE WOULD COMPLETELY DIE. THERE'S ALWAYS A MISFIRE CODE. THE VEHICLE APPEARED OK AFTER 5-10 MINUTES LATER BUT THE "CHECK ENGINE" MAY STAY ON. THE DEALER SERVICE DEPARTMENT SUSPECTED THE FUEL WAS BAD. WHAT'S IRONIC IS THAT THE ENGINE STALLED AGAIN WHEN THEY WERE DRIVING IT AFTER THEY DRAINED THE FUEL AND PUT IN NEW GASOLINE. THIS IS A BRAND NEW CAR FROM BUICK WITH ~600 MILES ON IT. SOMETHING IS SERIOUSLY WRONG...
