The problem
Chrysler Group LLC (Chrysler) is recalling certain model year 2013 RAM 1500 trucks manufactured manufactured June 25, 2012, through December 12, 2012. In the affected vehicles, the coolant bypass valve may stick in a position that does not allow coolant to flow into the heater core. Thus, these vehicles fail to conform to the requirements of Federal Vehicle Motor Safety Standard (FMVSS) No. 103, "Windshield Defrosting and Defogging Systems."
The risk
Without a properly working windshield defrosting system, a buildup of mositure or ice could limit the driver's ability to see, increasing the risk of a crash.
The fix
Chrysler will notify owners, and dealers will replace replace the suspect coolant valves along with an updated calibration, free of charge. The recall began on June 25, 2013. Owners may contact Chrysler at 1-800-247-9753. Chrysler's recall campaign number is N25.
