{: ) It is possible, but not always the case. An airbag light on your instrument cluster may mean several things. Usually under normal conditions, an airbag light on warns the driver that the airbag system has detected a fault somewhere in the airbag circuits and need to be checked or fixed, otherwise the airbag protection system may not work properly in the event of collision. It can be wiring or component malfunctions.
Sometimes it can be a deployed component like the seat belt retractors or an SDM, which you may not notice. Your vehicle needs to be checked by a diagnostic scan tool for trouble codes. This way, you can easily determine the status of your airbag system.
If your vehicle did have an impact before that you're not aware of, and no attempts were made to have it repaired despite previous airbag light warnings, well, you can always expect the airbag light to come on.

When an airbag warning light comes on, it is a warning that the system will not operate as designed in case of a crash. In most cases, the system is inhibited from any operation when that light is on. The manufacturers say that the airbag will not deploy under these circumstances but I disagree. I actually witnessed and airbag deployment in a vehicle with the light on, at approximately 2 mph. Have it properly diagnosed and repaired immediately.

when this light comes on it is a warning that the airbag diagnsotic montior has sensed a problem in the airbag systems electrical components, the source of the problem is stored as a fault code and can be retrieved with a factory scan tools. Whenever this light is on the airbag system is disabled

If the airbag warning light has started to come on, the only thing available is to bring it to the dealership. The airbag system is very complex and could deploy if a non-qualified mechanic works with it. Removing the fuse that operates the deployment switch will result in airbag not operating in the event of a crash. Please, take it to the dealer service department and have them check it out.

Most definitely electrical problem. Though GM connectors are quite reliable - they sometimes get misconnected or you have a poor connection. get it cehcked.

If the light is on, there's a fault stored in the computer. You have to get the trouble code to know what's going on. No way to guess your way out of this. Read this post on airbag lights
