Anti-theft Devices problems of the 2011 Chevrolet HHR

The above vehicle has been in for repairs 6-7times for intermit anti-theft light coming on while driving and a recall for anti-theft/air bag malfunctions. Intermittingly the car will also not recognize the key(s) and will not start. My concern for safety is when the car begins to ding while I'm driving and then the anti-theft light comes on it will also decide to stall because it does not recognize the key and thinks it's being stolen. (it has not done that yet, but it is a fear). I had the chevy 2014 anti-theft/airbag recall Aug 2014. In Dec 2014 my air bag light came on with a warning to repair. In Jan 2015 the anti-theft light came on 2 times. Walker jones chevy of waycross, GA detected no code for air bag. The anti-theft code revealed unrecognized key but no code to repair (Jan. 2015) the light has come on 5 times and not started on one occasion, since the recall repair. I am told by mechanics that the light must be on for them to retrieve a repair code. However, when the car is shut off the light goes off. The anti-theft light problem can wait months before surfacing again. I believe it could be dangerous to drive because of past cases of other similar cars with anti-theft/airbag issues. I have contacted chevy corporation but since I did not purchase a bumper to bumper warranty and no repair codes come up to show how to fix the problem its not their responsibility.
