Based on ballistic testing results, it has been determined that affected vehicles with registration history in high absolute humidity (HAH) areas are more susceptible to rupture. Owner notification letters were mailed to the owners of those vehicles on January 29, 2016. On Friday, February 12, 2016 initial owner notification letters will be mailed to the current owners of non?HAH vehicles. Non?HAH vehicles have not had any registration history in the high absolute humidity areas.
