USA - FCA recalls more cars for an update on the software for the air bag system.

FCA US LLC is expanding by an estimated 62,148 vehicles 

its recall of U.S.-market SUVs** to upgrade air-bag software.

The action follows a routine review of the originally reported vehicle population by FCA US engineers. There have been no additional incidents and FCA US is unaware of any related injuries or accidents.

The campaign will upgrade software that governs side-curtain and seat-mounted side air bags following a small number of inadvertent deployments – most of which occurred in harsh, off-road environments. They were prompted by maneuvers that dramatically changed the vehicles’ angle of operation, relative to the ground, and the air-bag systems – sensing potential rollover conditions – automatically activated.

The software upgrade will recalibrate the threshold for deployment and the vehicles will remain compliant with all applicable safety regulations.

Affected are certain 2014 and 2015 Jeep Cherokees. The revised estimate for the U.S. totals 230,240. Revised estimates for other markets are as follows: 28,110 in Canada; 6,367 in Mexico and 52,057 outside the NAFTA region. The revised global total is 316,774 – a difference of 68,593.
