My Toddler was seated (in the car seat that was buckled into ) the second row bucket seat. While driving the vehicle we hit a bump in the road which then launched the back passenger seat up and forward pinning my child between the two seats. His face smashed into the front passenger seat headrest which caused forced injury to his head. The EZ seat button could not have been reached by my child due to them being in a car seat. This has been reported to the manufacture of Nissan. There are no warnings for this feature.
