The subject Jeep Gladiator was involved in a side impact collision on June 18th, 2022. During the collision, the rear seat belts did not lock resulting in two children colliding with the rear of the two front seats. The side impact airbags did not deploy despite the impact being quite severe. The front airbags did deploy despite there being no impact to the front of the vehicle. Both the seat belts failing and the lack of side impact airbag deployment presents a safety hazard to the rear occupants of the vehicle in the event of a crash. The front airbags deploying without the requisite impact presents a safety hazard to front occupants of the vehicle. The seat belts still will not lock with any amount of pressure. The dealer will not discuss the issue and the insurance company, through a repair shop, currently has possession of the Jeep. There was no warning of any kind that the seat belts would not lock and the airbags would not deploy/deploy.
