Stellantis (FCA US) said earlier this week, that it would be issuing a recall for 76,000 of its 2017 to 2023 Chrysler Pacifica Hybrid PHEV (plug-in hybrid) minivans due to a short circuit issue that could cause the vehicle to stall unexpectedly.
The recall will cover around 67,000 units of Pacifica Hybrid in the U.S., while the other 9,000 units were sold outside the country. According to the FCA US, an internal transmission wiring connector may short circuit, resulting in an unexpected engine shutdown.
The Pacifica Hybrid uses a unique eFlite electrically variable transmission (EVT). Designed by FCA US, the device features two electric motors – both of which are capable of driving the vehicle’s wheels.
Conventional electrification schemes dedicate one motor to serve as a generator and a second motor – usually much larger – to deliver torque to the wheels. But the Chrysler Pacifica Hybrid uses a one-way clutch that allows the motor typically used only as a generator to deliver torque to the wheels, depending on driving conditions. The result is increased efficiency, refinement, and improved component packaging.
The blended PHEV design offers a seamless driving experience for the customer, whether in electric or hybrid mode for typical city and highway driving. Under normal driving conditions, the top speed in all-electric mode is approximately 75 miles per hour (mph).
When the battery’s energy is depleted to a certain threshold, the Pacifica Hybrid becomes a part-time electric vehicle, like a conventional hybrid, to maximize energy and efficiency. Power to the wheels is supplied by the electric drive system or supplemented by a specially adapted version of the 3.6-liter Pentastar V6.
FCA US says it was aware of 242 warranty claims, 6 customer assistance records, and 59 field reports that appear to be related to the issue. The automaker is unaware of any accidents or injuries related to the recall. The statement from the automaker says that roughly 0.2% of the vehicle population reported the stalling issue.
The fix will be through an update to the power inverter software. If needed, an update to the instrument panel (I/P) cluster software will also be done. FCA US, says the inverter helps to control the flow of electricity to and from the battery pack.
Stay tuned, as we will break down the official recall once more details become available.
