Chrysler is recalling more than 5,600 vehicles in two separate safety recalls.
About 3,850 electric cars may unexpectedly switch into neutral while 1,770 trucks include tires that are certified for a lower speed than expected.
A problem with the Electric Vehicle Control Unit (EVCU) in certain model year 2013-2015 Fiat 500 battery electric vehicles could set a diagnostic trouble code that may cause the transmission to unexpectedly shift to neutral. This significantly increases the risk of a crash.
Chrysler will notify owners affected by the recall and dealers will reprogram the EVCU, free of charge.
Certain model year 2014-2015 Ram 4500 and 500 cab chassis trucks equipped with 6.4L Hemi engines have a maximum governed speed of 106 mph, but are fitted with tires that are only rated for a maximum speed of 87 mph. If the vehicle exceeds the tires' maximum speed rating, the tires may suddenly fail, increasing the risk of a crash.
Chrysler has already started notifying affected owners, and dealers will correct the software to limit the vehicle's speed to 87 mph.
For more information about either recall, owners may contact Chrysler customer service at 1-800-853-1403.
