Was driving on both highway & neighborhood streets and the air bag fault light & warning tone came on. After many diagnosis drive tests, I learned that every time making a complete left u-turn the airbag fault indicator would disappear. However once completing the full left u-turn, and driving straight center wheel position, the airbag fault indicator light and warning tones would reoccur. When contacting my onstar monitoring service, they were able to do an over the air diagnostic fault code test. It came back as fault code b0012 for clockspring, driver steering wheel airbag deployment loop failure. Whenever the airbag fault indicator is activated on this model, the entire airbag deployment system is completely disabled and nonfunctional in preventing major injuries which can lead to fatalities. I contacted the dealership to inquire of the replacement clockspring part cost, and was quoted in the $450.00 range plus labor tech install. In addition, was told the part was on back order. It has been recognized as a known defect on this model and since is airbag related, should be corrected by the manufacturer, which is general motors. I could be like thousands of other owners to misinterpret the severity of this defect, and be driving a vehicle that will fail to save my life if ever involved in a major collision. This should not go unnoticed & should be investigated & resolved just like the one that was for other major car manufacturers for faulty airbag deployment issues. As to this date 06/11/2020 the issue keeps recurring on every drive on any street or highway. Thank you for serving your citizens & the commitment of making the automobile industry accountable for safety.

Passenger seat occupancy module - failure the failure of an electronic module located under the passenger seat, defaults the airbag system to "off". Cost is just under $1,000 for dealer replacement. Dealer indicated there was no method to turn on the airbag system - regardless of passenger or not. Because of this failure (many failures recognized since the 2006 solstice model) any passenger is subject to an unsafe condition without active airbag. The value of the vehicle negates the dealer cost to repair. Complaint filer feels the cost of the replacement module should be half of that quoted by the dealer since genuine gm parts are available at $275 instead of dealer cost of $417 and that labor of 2.5 hours to replace module under the seat is excessive based on time taken by others self-correcting the problem. (times indicated ran from 20 minutes to 45 minutes for most). Because of costs, many of these modules will (likely) go un-repaired and potentially un-reported if sold as a used vehicle..

I have gotten a "airbag fault" warning every time I start my car. Apparently this is due to a censor giving out and to repair the issue costs about $1000. This is highly unsatisfactory as many users of this particular vehicle have reported this issue when operating this type of vehicle under normal conditions. This in a sense renders the vehicle unsafe to operate as drivers (some unaware), whivh I was not, are operating the vehicle without any operable airbags. The cost to repair is very high for a feature that is a safety standard across the industry. The airbag system of a vehicle should never have any faults or failures unless it has been deployed or tampered with. It is quite disappointing that a system that has never been used or tampered with can have such costly faults/failures. This is an issue that needs to be addressed immediately. This is scary. I feel like some thing needs to be done to fix the problem. Gm needs to recall the module that will fix this issue asap. This air fault is putting many families at risk of loss of life!!! Bring attention to this issue or to what is causing it.
