A potential airbag mechanism malfunction is prompting Jaguar Land Rover North America to recall 40,551 SUVs, according to documents from the National Highway Traffic Safety Administration.

The recall covers the Land Rover LR2 from the 2010 through 2015 model years as well as the Range Rover Evoque vehicles from the 2012 and 2013 model years.

NHTSA indicated a component within the Occupant Classification System (OCS) Electronic Control Unit (ECU) may fail, resulting in the front seat passenger air bag being totally or partially disabled.

“In the event of a crash necessitating air bag deployment, if the air bag is disabled, the air bag may not deploy or may not deploy properly, increasing the risk of injury to the front seat passenger,” NHTSA officials said.

Land Rover told federal officials that it will notify owners, and franchised dealers will update the Restraint Control Module software, free of charge. The recall is expected to begin on Aug. 30.

In the meantime, owners may contact Land Rover customer service at (800) 637-6837 and mention recall No. P046.
