Battery Cable problems of the 2010 Chevrolet Impala

While traveling away from home I parked my car and the key is stuck in the ignition. This is a safety hazard due to I had to leave the keys in the car. The next morning the car would not start due to the battery being drained because the key was not in the off position. Therefore I had to be troubled with finding jumper cables while away from home or be towed to the nearest Chevrolet dealer (whom I might add did not have a technician that could fix it on a Saturday morning). I called another Chevrolet dealer in another county close by and their service department is closed on Saturday. So therefore I have had to either leave my vehicle running, loosen the battery cables or be close by to another vehicle that can give me a jump. (more inconvenience and safety hazards for a female) I notice while researching the problem online that this problem has occurred on the Impala since the year 2000. It is now 2013 and the problem has not been recalled or improved over the years. I feel this not only is an inconvenience to me (your customer) but also is a safety feature that has failed to exceed my expectations of driving a Chevrolet vehicle. I expect and hope that my inconvenience can have an impact on Chevrolet to not only take care of my problem but correct the situation and recall the problem so other individuals will not experience this turmoil. Research also reflected that the cost to me, the owner would be about $600 or more to fix the problem. Right now I am still with the key stuck in the ignition. (more inconvenience of being a chevy customer) I suppose I will expect a check in the mail to cover the expenses this has caused to me (your customer). Also a Ford dealer has stated they can fix the problem. I see something wrong with that picture. Bumper to bumper warranty has expired. . . . . Thank you for your attention to this inconvenience.
