THIS CAR HAS CONTINUALLY STALLED OUT AT DIFFERENT SPEEDS. I WAS TOLD IT WAS THE THROTTLE POSITION SENSOR SO I REPLACED THAT. THAT SEEMED TO FIX IT TEMPORARILY BUT JUST YESTERDAY I WAS DRIVING ON THE HIGHWAY AND THE CAR COMPLETELY CUT OFF GOING 55MPH PLUS.

VEHICLE OVERHEATED, ENGINE WENT INTO PROTECT MODE, DRIVER INFO CENTER DIRECTED ME TO SHUT DOWN VEHICLE, I PULLED OFF TO THE SIDE OF THE ROAD PROMPTLY AND SHUT VEHICLE DOWN. I WAITED FOR 15 MINUTES, TURNED IGNITION TO ON POSITION, AND IT READ IT WAS COOLED DOWN ENOUGH TO DRIVE. I TOOK OFF ONTO THE ROAD AGAIN, A HALF A MILE LATER, I HAD TO DO THE SAME THING. I WAITED 30 MINUTES FOR A SOME ONE TO MEET ME AT THE LOCATION, THIS PERSON RESTARTED THE VEHICLE AND DROVE IT 2 MILES TO MY HOUSE, WHERE IT OVERHEATED AGAIN IN THE DRIVEWAY. AFTER REPLACING THE WATER PUMP, BELTS, THERMOSTAT, AND RADIATOR, IT WAS DISCOVERED THAT THE HEAD BOLTS WERE INDEED WHAT WAS CAUSING THE VEHICLE TO OVERHEAT. THE MECHANIC FOUND THAT THEY WERE AT THE INCORRECT TORQUE AND THAT THERE WAS COMBUSTION CHEMICALS IN THE COOLING SYSTEM. I NOW AM REPLACING THE GASKETS, BOLTS, AND MAY HAVE TO GET THE HEADS MACHINED, BUT WORK HAS NOT BEEN COMPLETED ON THE VEHICLE AS OF YET. *TR
Official recalls
114V355000 · Electrical System:ignition
Jun 23, 2014
This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Consequence & remedy
Consequence: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), and 1-800-222-1020 (Chevrolet). GM's number for this recall is 14299.
