You can't just get a recalled airbag replaced immediately. There is a backlog. But if you have a vehicle younger than six years old, you are safe for a while. The government says the risk increases as it ages.
If you have a used car know that dealers can legally sell a used car without telling you about open recalls. So you might not know anything about it unless you check. The government VIN search goes back 15 years.
In the meantime, experts say don't disable your airbag. NHTSA says that you are more likely to be saved by an airbag than killed by one.
