Battery problems of the 2009 Chevrolet Cobalt

I started my vehicle up and parked it in the garage. When I went to remove my key from the ignition, the key wouldn't turn and I couldn't get my key out. In order to turn the car off, I had to remove the fuse and unhook the battery. I'm taking the car to schmidt Chevrolet in centralia, IL first thing tomorrow, but there is no active recall on my vehicle at this time. I see that his has been an issue for multiple Cobalt owners and even the mechanics that I was able to get a hold of told me that this is a known issue. I believe that my vehicle should be included in this recall and that any money spent should be refunded to me by Chevrolet for a poorly designed ignition.

Key is stuck in ignition in the on position. Car will not turn off. Had to disconnect the battery (while car is running) to turn off. Although support bulletin 10256 references this exact problem with 2009 Cobalts, gm and dealer are saying that my car is not included in this and I have to pay to get fixed. The support bulletin says dealers fix at no cost through January of 2013. But. . . My VIN was not included in the support bulletin. This is a serious issue. My daughter was not home when this happened. Having to disconnect the battery while the car is running and damage that may be caused to other equipment because of connecting and disconnecting the battery. I see so many reports of this problem online with some people having issue. How do we get the list of VIN's updated. How do we get the word out to customers that this is a known problem. I am very upset that I have to pay for this. I was told that a key getting stuck in the ignition is a common problem. Gm did compromise with me with my deductible but I honestly think this should have been a recall and I should not have to pay for a known issue.

No incident has occurred at this point, however, I see this as a potential safety hazard. I have a 2009 chevy Cobalt with battery installed in the trunk. The battery vent tube is connected to the top of the battery by a plastic elbow, a plastic vent tube is connected to the male nipple on the elbow. The plastic vent tube inside diameter appears to be too small inside diameter for the male nipple. The plastic vent tube is split where it attaches to my battery where it is pushed onto the male nipple which will allow the vented hydrogen gas to vent into the trunk (which is part of the passenger compartment only separated by the back seat) I think presents a potential safety hazard and potential fire risk. I can send you a picture of the split vent tube if you need to see it. I assume that this is a factory installation defect, this is not an improper repair defect, so this situation could exist on other models using this type of vent tubing.
