We bought the car with the extra precautions but they failed to meet their expectations. What are our rights dealing with this.
Every lawsuit needs damages, and generally the rule is "no harm, no foul." There has to be a causal relationship between the thing you're complaining about and some damage, and you've listed this question under personal injury, but you haven't connected the airbag malfunction with any injury. Did the failure of the airbags to deploy cause some damage? Pehaps you'd like to re-submit a question here with more facts or consult a defective products lawyer.

You haven't explained what your injuries are and what they would have been if the airbags had deployed. Although its possible they were defective, its also possible that the crash did not meet the specifications for the air bags to deploy. Not all accidents are of sufficient force to cause air bags to deploy.
In addition if you want to make such a claim you better make sure you preserve the evidence, i.e. the vehicle and all the air bags for future litigation.

The repair shop will check to verify that the vehicle is or is not performing within factory specifications. If it is not, you may have recourse under the manufacturer's warranty. It is also possible that non deployment under the circumstances was normal and within specifications.
