John bought a new automobile. Shortly after he purchased the vehicle, he was involved in an accident and his airbag failed to deploy. As a result John was seriously injured. John sued the manufacturer for damages as a result of the failure of the airbag to work. John can not prove that the manufacturer was negligent in any way. Therefore, the manufacturer states that it is not liable to John and that John is not entitled to prevail and recover damages from the manufacturer. Does John have to prove that the manufacturer was negligent in order to prevail? If so, what elements must be proven? If not, can John recover under another theory? Explain thoroughly.
