My vehicle and many others as well suffer from a intermittent problem of the pass lock security safety feature. There are times when inserting the key in the ignition the vehicle would not start because the pass lock fails to recognize the key. When this happens a security lock indicator on the dash flashes. To overcome this the ignition has to be placed in the �off the on � position and let it remain so for at least 10 minutes. After such time the vehicle will star until a undetermined time the discrepancy occurs again. Besides my vehicle I have found this condition to exist on many owners on this type and other gm models as well and as far as I can tell from 2006 and on. It's a inconvenience plus if for some reason there was a emergency of some kind the owner would not be able to start it's vehicle and it would not know when or where it's it is a intermittent problem. So you can be on street, on a curve off the highway or any area stationary. The Chevrolet high resolution team is aware of this problem and does not consider it important enough to address this other than having the ignition lock housing replaced , ignition key replaced, and having new key programmed .

On February 14, 2012 I was driving on a clean, dry, straight, and level road at 35mph. I was not accelerating, braking, or cornering. The alarm bell rang and the dash board display indicated "traction fault, reduced power, service stability system". The vehicle dramatically reduced it's engine power to the point it could not be safely operated in traffic. It was impossible to accelerate with traffic, merge, or make a left turn. I was about 3 miles from the dealer. I drove to the dealer to have it looked at right away. They told me I had no appointment so they would not look at it. I got the next available appointment two days later. The vehicle was not driven from the time of the alarm until the time of the appointment. On February 16th I took the vehicle to the dealer and it operated at full power. There were no lights or alarms. The dealer said the computer had a history of something but did not retain the details. They said general motors warranty policy would not allow them to repair the vehicle without a specific trouble code that would allow them to minimize the warranty expense. I informed them that they made me leave two days prior when it was operating under reduced power and showing alarm details in the dash display. They should have diagnosed and/or fixed it then. It is unacceptable that the vehicle creates a safety issue by reducing engine power when there is nothing wrong. It is equally unacceptable that an issue serious enough to cause reduced engine power is not retained by the computer so it can be diagnosed and repaired. This is likely to cause a vehicle accident where someone could be injured or worse. They did tell me that if I paid for the extra cost onstar system it could have given the details on the problem. If the vehicle requires onstar to safely operate, it needs to be a free service.
