Fiat Chrysler Automobiles (FCA) is conducting yet another safety campaign, covering almost 400,000 units of the Jeep Wrangler, whose airbags may not deploy in the event of a crash.

The issue has been tracked down to the clockspring assembly in the steering wheel, which is part of the circuit that helps control airbag function. This might cause excessive exposure to dust and dirt from driving off-road or with the vehicle’s top and/or doors removed.

If the clockspring assembly is compromised, then the airbag on the driver’s side may fail to deploy in case of an accident. However, the airbag warning-lamp will illuminate and FCA advises owners to contact their dealers if such an event occurs. The company is not aware of any accidents or injuries related to this condition.

The repair will be made free of charge and will include the installation of a new steering wheel back cover and a steering column shroud. Affected vehicles include 392,464 units of the 2007-2010 Jeep Wrangler SUVs, along with an additional right-hand drive 7,435 examples from the 2011-2016MY. FCA estimates that Wrangler that will have to be driven back to the dealers, outside the US, comprise of 35,412 in Canada, 8,529 in Mexico and 62,580 outside the NAFTA region.
