Chrysler is recalling 744,822 Jeep Liberty and Grand Cherokee SUVs in the U.S. for airbags and seatbelt pre-tensioners that can inadvertently deploy or activate, according to filings posted Friday with the National Highway Traffic Safety Administration.

Chrysler also recalled the SUVs in Canada (49,430), Mexico (21,828), and in other markets including Europe (103,465), the company said. In total, 919,545 vehicles are affected.

Circuits within the airbag control module can fail due to "electrical overstress" and cause the front or side curtain airbags to deploy without warning on 2002-2003 Liberty models and 2002-2004 Grand Cherokee models. NHTSA had been investigating the Liberty models since October 2011 and has received 126 cases of inadvertent airbag deployment, resulting in 59 "minor injuries."

In January, NHTSA included the Grand Cherokee in the investigation after receiving 89 reports of inadvertent deployment, resulting in 22 minor injuries. In October, a Chrysler supplier told the company that a different metal had been used in certain capacitors within the airbag system, from which Chrysler concluded that electrical faults had triggered the airbags.

Chrysler dealers will install a new jumper harness that will fix the problematic components, Chrysler said. However, the parts will not be available until January. Chrysler did not say if owners should stop driving the vehicles. If you see an airbag light on the instrument panel or hear a warning chime, we'd recommend you do. NHTSA reports indicate that the inadvertent deployments occurred shortly after the light or chimes were activated.

Between March and June, the Liberty was recalled for suspension fractures on 2004-2007 models, a total of nearly 347,000 vehicles.

This latest Liberty recall is the seventh and largest airbag recall this year. Other manufacturers including Scion, Mercedes-Benz, Ford, Dodge, Hyundai and Chevrolet have issued recalls relating to inadvertent deployment, deflation problems or issues with sensors.

After an MSN Autos investigation in August found at least 19 cases of inadvertent airbag deployment in Cadillac and other GM vehicles, neither NHTSA nor GM has taken further action to investigate. However, NHTSA is investigating the 2012 Hyundai Elantra for side curtain airbags that deploy improperly, based on a single complaint.
