In the latest phase of its NHTSA-supervised programme, FCA US is recalling about 1.4m vehicles in the US to replace Takata passenger side airbag inflators that may, on deployment, send shrapnel into the vehicle cabin.
Last week, Toyota announced the recall of 1.7m vehicles in North America to replace faulty Takata front passenger airbag inflators, including 1.3m in the US, while Ford announced a fourth round of recalls of vehicles fitted with the troubled and now dismembered supplier's products.
FSA noted the was linked to temperature cycling, humidity and time and said this his recall was the fourth and final phase of a coordinated schedule established by the National Highway Traffic Safety Administration, and developed to "capture" defective airbag inflators produced by the former Takata.
To date, FCA US has replaced more than 4m Takata inflators.
"However, the company's inventory of replacement parts has outpaced demand for service [and] we strongly urge our customers to respond to their recall notices…," said Mark Chernoby, FCA's head of North American safety and regulatory compliance.
"Recall service is free, we have replacement parts and dealers are ready to help."
