Chrysler, a unit of Fiat Chrysler Automobiles,
said it was unaware of any injuries or accidents related to the
issue in either recall. All the affected vehicles are in the
U.S. market.
Affected in one recall are an estimated 23,053 Ram ProMaster
full-size commercial vans from model year 2014, the automaker
said.
Chrysler said it would upgrade the software that helps the tire
pressure monitor sensors recognize the tire from where the
pressure data is coming. Absent that capability, a warning light
may falsely signal tire pressure is low, raising the possibility
the system may not properly alert drivers if tire pressure
actually becomes too low.
The second recall affects an estimated 10,390 Jeep Wrangler SUVs
and Dodge Grand Caravan/Chrysler Town & Country minivans from
model year 2014, Chrysler said.
The company plans to reconfigure a tire pressure monitor module
to disable a test mode that was inadvertently left on following
shipment from the supplier. When installed, a module configured
that way may not get an accurate tire-pressure reading, which
could result in a false warning.
Chrysler said it would notify owners of the vehicles in both
recalls next month and tell them when they may schedule service,
which will be free.
