Air Bag Not Deploy problems of the 2017 Hyundai Tucson

Airbags failed to deploy at utility pole collision.

Tl the contact owns a 2017 Hyundai Tucson. The contact stated that the transmission slipped and the vehicle jerked violently sometimes. On one occasion, in a shopping plaza parking lot, the vehicle jerked violently, the steering wheel seized, and the vehicle accelerated on its own. The brakes failed to operate and the contact's vehicle crashed into a parked vehicle twice. The air bags did not deploy. The contact sustained injuries to the neck and back, which required medical assistance. A police report was filed. The vehicle was towed by the police to an independent mechanic. The vehicle was then taken to an insurance body shop to be diagnosed, but a failure could not be located. The body damage was repaired. The failure mileage was 2,000.

Passenger air bag off light remains on whenever an adult weighing more tha 120 lbs are sitting in the passenger seat with a small pillow or seat cushion on the seat. Pillow is needed to enhance seating comfort, especially on long road trips. Light does work when pillow is not used. Unfortunately, seat is poorly designed that requires additional after market support to make it usable on long trips. Sensor need to detect passenger weight with or without additional cushions or activate the airbag 100% of the time. I have already reported this to Hyundai, case number 10626629. They claimed the light is working as designed, only when used without after market cushion. My response is that it is a major safety defect in design, it obviously failed in detecting the total weight on the passenger seat. I believe that Hyundai would be at fault should the airbag failed to deploy during an accident and the passenger is seriously injured or killed. There are additional reasons to use cushions for health or handicapped person, for example. How hard is it to detect total weight of more than 90 lbs on top of that sest? the light remains off when car is moving or stopped. In addition, I have also experienced no acceleration on a left turn when stepped on gas, as previously reported by other's. Engine would rev to over 2000 rpm but the car us not moving for about 30+ seconds. This is a very serious safety issue when you're stuck on a left turn.
