One problem related to air bag not deploy has been reported for the 2013 Land Rover Range Rover. The most recently reported issues are listed below.
Dashboard is heaving, separating and exposing the airbag on passenger side. Dealer cannot repair but said that if the separation becomes larger the airbag may not deploy in the proper direction or may deploy unnecessarily.
