Do I have a good case to sue if my airbag didn't deploy?

Fortunately, it does not sound like you sustained any significant long-term injuries and as such, a product liability claim for the air bag failure is probably not worth pursuing. You can and should report the issue but it may not be worth pursuing. You should focus on your recovery and you can also pursue the at-fault driver for your injuries, expenses and pain and discomfort. You should contact an attorney to obtain a free consultation so that you can discuss your situation in greater detail.

That is a mixed question requiring an automotive engineering opinion on whether the air bags were defective and a doctor's opinion on whether the injuries were caused by the failure of the air bags to go off. It may even require another expert's opinion as well. My guess, though, is that unless your injuries are really severe, the cost of bringing such a claim would outweigh any potential recovery.

If the sensors were activated but did not deploy the airbags, then you have a case.

First off it does not sound like you were hurt bad. Secondly. An airbag is not a guarantee that you will not be hurt it is designed to keep you from serious injury like being thrown into the windshield. Thirdly, you must prove by engineering testimony how and why it failed and finally the doctor must testify as to medical causation of the injury and I doubt a doctor would draw a very fine line for you. How could he? And you would likely have to pay your experts in advance and finally finally what lawyer would want to take your case on a percentage? And finally how old is the air bag? Does it have a warranty? Has it been damaged before. You have not thought about any of this have you.

Since it was the other driver's fault, the easier case is against the other driver. Since you say that you are fine, the other driver's insurance coverage should be adequate cover your damages. The only reason to bring a suit against the manufacturer would be if the other driver's insurance is inadequate to cover your damages. To bring such a case, you would have to hire an expert witness to testify that the air bag failure was due toa manufacturing or design defect, and your doctor would have to testify that your injury would not have occurred, or would have been less severe, had the air bag deployed.

Potentially you could have a products liability claim.
