WHILE DRIVING THE CAR, IT STALLED AND CUT OFF WHILE IN THE MIDST OF MAKING A RIGHT HAND TURN. ALL POWER WAS ON TEMPORARILY BUT THE ENGINE WAS UNABLE TO TURN OVER AFTER CUTTING OUT. THE DEALERSHIP IS UNABLE TO DIAGNOSE THE ISSUE, AND APPARENTLY THE ISSUE HAS OCCURRED BEFORE TO THE PREVIOUS OWNER. THE CAR IS STILL UNDER A 5 YEAR 100,000 POWERTRAIN WARRANTY. IT APPEARS NO PROPER DIAGNOSIS HAS OCCURRED AND THIS ISSUE HAS BEEN OCCURRING ON THE CAR SINCE APPROX. 52,000 MILES CURRENT MILLAGE IS 75,900. I HAVE REFERENCED PREVIOUS TSB NHTSA ID 10037218 TO THE DEALERSHIP AND HAVE RECEIVED NO RESPONSE AS OF YET AS TO THE UNDERLYING ISSUE. I HAVE DISCOVERED OTHER OWNERS HAVING SIMILAR ISSUES ON WEBSITES SUCH AS CARCOMPLAINTS.COM AND VARIOUS BUICK REGAL FORUMS. THIS APPEARS TO ME AS A MAJOR SAFETY ISSUE AS WHEN THE CAR SHUTS OFF IT DOES NOT POWER BACK ON, AND IT CUTS SEEMINGLY RANDOMLY.

THERE WAS A RECALL OF THE KEY AND "FOB" FOR 2010-2014 CHEVY CAMAROS BECAUSE THE KEY COULD BE BUMPED BY SOMEONE'S KNEE OR SOME SIMILAR ISSUE. THE KEY OF MY 2011 BUICK REGAL BROKE, AND I BELIEVE IT HAS THE SAME CONSTRUCTION AS THE CAMARO. BY BROKE I MEAN THAT THE METAL PART THE FLIPS THE KEY IN AND OUT THE FOB (WHEN YOU PRESS A BUTTON) ACTUALLY BROKE, LUCKILY WHILE MY WIFE WAS TURNING OFF THE IGNITION. I THEREFORE SUSPECT THAT SINCE THE CAMARO AND BUICK ARE BUILT BY GM AND PROBABLY SHARE THE SAME KEY/FOB DESIGN, I'M EXPERIENCING THE SAME PROBLEM AS THE DRIVERS OF THE RECALLED CAMAROS, AND THE KEY/FOB OF THE 2011 BUICK REGALS SHOULD ALSO BE RECALLED.

IT MAKES IT DIFFICULT WHEN MERGING ON FREEWAYS. I WAS ALMOST INVOLVED IN A CAR ACCIDENT WHEN THE FIRST INCIDENT OCCURRED DUE TO SLOW RESPONSE OF ACCELERATION. MAF HAS BEEN CLEAN. THE A NEW MAF WAS INSTALLED. NOTHING HAS CHANGED. ALSO I AM NOT SURE IF THIS IS RELATED BUT I CANNOT RUN MY AIR CONDITIONER UNTIL THE CAR HAS BEEN RUNNING FOR A FEW MILES. IF I DO THE COMPRESSOR WILL MAKE AN AWFUL NOISE. AN ODOR HAS STARTED TO COME FROM THE VENTS WHEN THE AIR IS NOT RUNNING.
