WASHINGTON — Fiat-Chrysler is recalling 667,406 2013-'15 Ram 1500, 2500 and 3500 trucks in the U.S. to fix airbags that may deploy unexpectedly, increasing the risk of a crash or injury, according to the National Highway Traffic Safety Administration.
"In the affected vehicles, the side-impact sensor calibrations may be overly sensitive, and as a result, the side airbag inflatable curtains and seat airbags may unexpectedly deploy and the seatbelt pre-tensioners may activate," said NHTSA in its recall summary.
Fiat-Chrysler said it is aware of "two potentially related injuries, both described as minor, but no accidents."
The automaker launched an investigation of the problem following customers complaints of inadvertent deployment, which it said accounts "for less than 0.005 percent of the population, almost all of which occurred when vehicle doors were slammed with excessive force."
The low-deployment threshold is in four-door vehicles.
The affected vehicles were built from June 20, 2012 to January 26, 2015.
Edmunds says: Fiat-Chrysler is urging owners of these Ram trucks to "exercise caution when closing doors." The recall is expected to begin within 60 days, but owners with an immediate concern should contact their dealer now.
