“While I was driving down the road, both curtain side air bags deployed at same time. There were no other cars on the road, so I was able to stop the vehicle without causing an accident. The airbag on the driver side pushed me over so hard that it broke my center console. My lower back still hurts, but I am hoping the pain will go away. My left ear is still ringing and has not returned to normal hearing yet caused from the exploding noise from the airbag deployment. …”

“On may 24, 2012- I was traveling out our mile long gravel driveway. Half way down the driveway the side curtain airbags on both sides deployed. There was no crash- they just came out. I contacted GM. They finally sent out a 3rd party investigator to investigate the vehicle. They determined that the vehicle had a roll-over event. The vehicle did not roll-over. Gm told me that it was an insurance issue. Insurance company says it is a mechanical issue and was GM's problem to fix. …”

NHTSA complaint #10472374, filed 2012-08, 104,000 miles

“This complaint is in conjunction with my false and delayed side curtain airbag deployment, report date of march 25, 2009. I just discovered that both front seat belt systems must be replaced. The drivers side seat belt is limp. The passenger side seat belt is so tight it not only broke top of the belt housing on top of the seat (pieces), the belt is so tight it is deforming the seat. I cant imagine what this would have done to a passenger, had I have had one in that seat.”

NHTSA complaint #10263133, filed 2009-03, 1,066 miles

“On a exit ramp (concrete) going about 30 MPH when both side air bags unexpectedly deployed, brake pedal went all the way to the floor, no braking, pumping the brake corrected them and stopped the car. Brakes now seem normal. Both front seat belts are now locked. The car has no damage on the body or tires. G m has opened a case for us. Waiting their call back.”
