WASHINGTON — Chrysler is recalling 381,876 2010-'14 Ram 2500, 3500, 4500 and 5500 pickup trucks and chassis cabs globally because the diesel fuel heater may overheat, increasing the risk of a fire, according to the automaker and the National Highway Traffic Safety Administration.
The trucks are equipped with the 6.7-liter Cummins diesel engine.
"In the affected vehicles, the electrical connectors of the diesel fuel heater may overheat," said NHTSA in its summary of the problem. "If the connectors overheat, the fuel heater may leak fuel, increasing the risk of a fire."
The affected trucks were built from March 27, 2009 to September 5, 2013.
"Chrysler Group is unaware of any incidents involving fire," the company said in a statement.
There are no injuries or accidents linked to the recall.
"Chrysler Group engineers discovered a terminal connector near the fuel heater may be subject to friction-induced corrosion," Chrysler said.
The recall follows an investigation of two cases in which fuel-heater housings showed signs of overheating.
An estimated 314,704 trucks are in the U.S. The rest are in Canada, Mexico and outside the NAFTA region.
Chrysler dealers will replace the harness side connector with a silver-plated beryllium copper terminal service kit and inspect the fuel heater for leaks, replacing it as necessary.
The recall is expected to begin on December 5. Owners can contact Chrysler at 1-800-853-1403.
Edmunds says: Owners will be notified by Chrysler and advised when they may schedule service. But if you own one of these trucks and are experiencing a problem, contact your dealer now.
