The official notice
Defect
On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, could eventually degrade the propellant contained in the passenger frontal airbag. This could cause the airbag to deploy with more force than normal. As a result, if the vehicle were involved in a collision that warrants airbag deployment, fragments could be propelled toward vehicle occupants, and the airbag assembly could be damaged, preventing proper function. These issues could increase the risk of injury.
Safety Risk
No risk description available.
Remedy
Dealers will replace the passenger frontal airbag module.
