Problems with 2007 Cadillac STS STRUCTURE

I was at a complete stop. i started going up the driveway, i felt the car lurch foreward. i thought i was slamming on the brake, but hit the gas instead. the car crashed into the house moving the concrete block. the airbags did not deploy. i broke my neck at c4 and c5. i have seen 3 reports on this site detailing the same. all these cars were 2007 cadillac sts. with all the problems with gm and airbags, could this be related? *tr

2007 cadillac sts bought as a demo in florida in april, with about 3,500 miles on it: i told the salesman that this was going to be used exclusively at my connecticut address and i would be driving it there shortly after purchase. my complaints are first with the conditions of sale in florida, and subsequently, with the failure to repair issues both in florida and now connecticut. i bought the vehicle with the agreement that it would be made 'as new as possible.' this was to include a new battery (since it was dead in the showroom), the oil would be changed, and all the door and dash scuffs would be removed. the battery has finally been replaced here after failing twice, the scuffs they fixed in florida keep coming right back on the doors and dash, and i just paid for the oil change that never took place for the sale. the day i drove the car off, the salesman indicated they 'topped it off.' it was into service at least three times within the first weeks of ownership in florida. it has already been in for service three days here in connecticut, my last visit to service was for two days, and nothing was done or solved. the voice command system just doesn't work properly. it continues to hear me incorrectly, or hears/repeats me correctly but then does not do what it says. as you use the wheel button to progress through the six presets and go back to the first, it skips over the first and sometimes the second button. to make matters worse, the volume periodically takes off with increasing loudness uncontrollably. in any case, they tell me that corporate is aware of the voice problems and has been trying to come up with a software fix. to my thinking, this is an '07 and they haven't come up with a fix for it yet? if it hasn't been fixed yet, it is not going to happen late in '08 and they claim i am not alone with these issues! *tr
