Front Air Bag Sensor Control problems of the 2015 Volkswagen Jetta

I have owned this used vehicle for 3 months. When attempting to apply the brake at low speed (10-15mph) the brake pedal stuck in place and would not go down. This brake failure resulted in an accident. During said accident, at low impact, the airbag was triggered to deploy. This leads me to believe the airbag or sensor is defective, as I have been in a much more serious accident with an older Jetta that did not result in airbag deployment. I am at risk of having my vehicle totaled out because of these issues when it normally would be repairable.

Passenger seat occupancy sensor is poorly designed and anything placed on the seat initiates the sensor and the fasten seatbelt light and gong. Items that cause this condition has been fast food, small dogs, paperwork, a cell phone on a charger, my cd case. I rented an identical vehicle from hertz and this issue did not happen. Looking into the problem online this has been a problem with many owners stretching back to 2011 model years. If the seat sensor senses something on it and there is a wreck both airbags will be deployed further risking the driver to flying debris. Dealer claims this is a normal situation. Since some vehicles are having this problem and other vw products are not I kinda doubt it.
