What owners say about the electrical system

Verbatim from NHTSA complaints, newest first
“Remedy for campaign 14V047000 was executed defectively, creating an unsafe mechanical failure that destroyed the powertrain. Failure occurred while or shortly before vehicle stalled in heavy traffic. Vehicle would not restart, but ignition switch stuck in start position while attempting restart, causing starter motor to crank continuously until the switch was turned to the off position. It is believed that starter motor was running while engine was running since last successful start about 3 minutes prior to stall, interfering with normal operation of the engine and eventually causing engine to jump timing and sustain catastrophic internal damage. Subsequent GM dealer service visit found that a burr on the new key provided with campaign 14V047000 repair caused ignition switch to bind in start position. Service staff buffed out burr on key which resolved switch binding, but vehicle refused to start. Borehole inspection of engine found damaged valves and pistons, leading to diagnosis of jumped timing. No other work other that diagnosis has been attempted at this point. Estimate to replace engine is $8600”

“Needless to say, General Motors has dealt with their share of recalls lately and while much of the GM recall news has been devoted to the ignition failures which have forced new CEO Mary Barra to stand before the US Government, this new recall has nothing to do with the ignition cylinder failures. Although the ignition problems can cause a steering issue and some of the vehicles included in the ignition recall are also included in this new recall, this recall pertains specifically to the power steering system. It seems that in the 1.3 million affected vehicles, one or more components of the electric power steering assist system could fail and when that happens, the car will not have the same level of power assist. The General Motors statement announcing this recall is a bit on the vague side in terms of explaining exactly what is causing this loss of power assist, but the automaker has explained that it could be due to a problem with the power steering motor, the steering column assembly, the power steering control unit or a combination of the power steering column and the power steering control unit. Regardless of which of those components fail, it will become…”

“HELLO, HOW ARE YOU? THE TRACTION CONTROL WARNING LIGHT STAYS ON AND THE BUTTON CANNOT TURN IT OFF. THE ENGINE LIGHT STAYS ON AND THERE IS A SERVICE PROMPT ON THE INFORMATION SCROLL LCD SCREEN. THE CRUISE CONTROL SWITCH LIGHTS UP BUT THE CRUISE DOES NOT ENGAGE WHEN THE SET BUTTON IS PRESSED AT ANY SPEED, IE, 30MPH, 50MPH, 55MPH ETC. THE RESEARCH I READ RECOMMENDS TO CONTACT YOU TO HELP GET THIS VEHICLE INCLUDED IN AN EXISTING RECALL FOR THE SAME ISSUES IN OTHER GM VEHICLES WITH THE SAME EQUIPMENT. IN OTHER WORDS, THIS VEHICLE HAS THE SAME DEFECTIVE EQUIPMENT AS OTHER GM VEHICLES THAT HAVE BEEN RECALLED FOR REPAIR. DUE TO THE FACT THAT THIS VEHICLE HAS THE SAME DEFECTIVE EQUIPMENT THAT WAS RECALLED IN OTHER GM VEHICLES I REQUEST THIS VEHICLE BE COVERED UNDER THE SAME RECALL AND ABLE TO BE REPAIRED AS SOON AS POSSIBLE.”
