Who are we kidding with this recall? (the federal safety agency 14v355, gm 14299) correcting a faulty ignition switch with an extra key ring and a paper to add to the owner's manual is a lawyer's solution. Is this a design defect, or is it not? Why is it not adequate? 1) it does not insure that the weight of the keys will not cause shutdown. It only makes it a little less likely. 2) in a year's time, even the current owner's will have forgotten the solution. Even if it's in the car's manual, does anyone ever actually read the manual end-to-end?. Let alone rereading it regularly to refresh their knowledge? It's only there, if at all, for reference. 3) how many second owner's even get the manual? How many will get keysets with the extra ring? My experience is few, if any, subsequent owners will have any reminder of this recall. Let's get serious and be responsible. If there is a design or manufacturing safety defect, then fix it! Deflecting liability to the owner is horse-pucky!

We were stopped at a red light and the car just died. We called aaa and before they got there the car started up again. Then we received a recall notice from gm (recall #14299). Since parts are not available according to the letter we removed everything from the keychain leaving only one single key as instructed. However, our car again died on august 21, 2014 but after a few minutes started up again. Today, august 31, 2014 our buick died again in the left turn lane stopped at a red light. We had to be towed home by aaa because it would not start again. This is unacceptable!! We are an 80 year old couple and we only have this one car for transportation. We cannot keep worrying about our car everytime we drive it, much less the dangers of having an accident when it stalls in the most unexpected places and times. We need a rental car to use until gm can get these parts. I don't think that I am asking too much.
