Air Bag On-off Switch problems of the 2009 Chevrolet Colorado

The truck is still experiencing "no-starts". I have been in correspondence with gm to try to resolve the issue for quite some time, now. I purchased my truck from van Chevrolet in carrollton, texas on July 27, 2009. I was not aware of a recall on the fuel system control module( recall #08411 beginning may 18, 2009), nor was I informed of it by the dealership. Smart Chevrolet of white hall (formerly of pine bluff) claimed to have repaired it in 2011, however I have had even more issues since then. Smart claimed to have replaced a brake lamp switch, a clutch safety switch, repaired a broken wire in the left door jam area, replaced a battery (my cost), without my permission to do so, reset sensors which they refused to explain the type of sensors they reset (my cost), reset oil life sensor, (no record of oil change) and I have had to replace the right side headlamp twice myself. Smart blamed the "no-starts" on my locking gas cap and the floor mats, and on my last visit to their dealership, refused to witness (for gm) the" no-start" in their parking lot. Two other dealerships have taken a look at the truck and I paid for repairs of a seat belt pretensioner ( cause of airbag light), and have been refused an invoice and to be charged to show the repair of the broken wire in the same door jam (Smart supposed to have repaired). This dealership admitted witnessing the "no-start" then changed their story after speaking with gm. The last dealership, after talking to gm, tried to also say that the "no-start" was due to the floor mat. I experienced "no-starts" before I had the locking- gas cap(made specifically for the 2009 Colorado truck) or my truck floor mats. Gm offered a subscription to on-star and a $2,000. 00 loyalty voucher towards the purchase of a new chevy vehicle in their words "to satisfy me" (joke, right !) the key is turned in the ignition, the car does not crank.
