Answer:
Toyosan's air bag was defective because it did not meet the expectations of a reasonable consumer.
Step-by-step explanation:
Product liability is defined as the liability that a producer of a product bears for putting a defective product in the hands of the consumer.
In this instance despite deployment of the airbag Emily still hit her head against the steering wheel, causing damage to her face and teeth.
The product is a defective one as it does not meet expectations of a reasonable consumer. That is to offer protection in case of car crash.
