In a crash that deploys vehicle air bags to protect occupants, the passenger seat air bag may not deploy, increasing risk of injury. Dealers will replace the passenger seat air bag free of charge to resolve the problem.

The occupant detection system may unintentionally shut off the passenger front air bag due to a sensitivity issue in the sensor mounted within the passenger seat cushion. Dealers will replace the passenger side seat cushion which includes the sensor free of charge to resolve the concern.

These vehicles are equipped with a new type of A/C refrigerant - R1234yf. Testing has determined that escaping R1234yf refrigerant may ignite under specific conditions. A severe frontal crash may rupture one of the air conditioner refrigerant lines, which can result in a gaseous mixture of refrigerant being released into the engine compartment. The resulting fire could spread to additional combustible materials. Dealers will replace the R1234yf refrigerant with R134a (which is the type that had been used previously) along with new refrigerant lines (hoses) designed specifically for R134a.
