2012 Nissan Rogue air bags problems

Frontal impact caused airbags to deploy except the passenger front (no passenger) and the passenger rear side (passenger present) . Nissan claims no deployment of side airbag is because no direct "t-bone" impact on passenger side of vehicle was sensed. Nissan also claims that the driver side airbag did properly because it sensed a potential rollover situation. Nissan was moving on city street and hit (t-boned) a truck pulling a heavy loaded trailer that ran a red light.

My mother purchased this nissan rogue new in 2012. Now the airbag light is on, we're being told that none of the airbags inside the vehicle are working. South austin nissan where we purchased the vehicle refuses to assist my mother, unless she pays a great deal of money. Nissan corporation refuses to assist, they just refer me back to the dealership. So many of these airbags have been recalled, therefore why is my mother having to pay a large amount of money.
