The Chrysler eFlite is a multi — speed, electronically controlled hybrid transaxle designed for plug — in hybrid electric vehicles (PHEVs). It integrates a 3.6L Pentastar V6 petrol engine with dual electric drive motors and a 16 — kWh lithium — ion battery pack. This configuration delivers combined system outputs of 225 kW (302 PS) and 549 Nm of torque, prioritizing seamless power delivery and electric — only driving capability.

The Chrysler eFlite powertrain is used exclusively in the Chrysler RT platform with transverse mounting. This integrated system is not offered in any other model or by any other manufacturer. All adaptations and calibrations are documented in OEM technical bulletins.
The eFlite's primary reliability focus is on the high-voltage battery system and associated thermal management, with elevated incidence of cooling fan control issues in early production vehicles. Stellantis internal service data indicates that while the mechanical components are robust, electronic control modules for the hybrid system are the leading cause of diagnostic trouble codes. Maintaining software updates and ensuring proper battery cooling is critical.
Analysis derived from Stellantis technical bulletins (2017-Present) and UK DVSA failure statistics (2018-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The eFlite powertrain is generally robust, with the 3.6L V6 engine being a proven design. Its main long-term concerns are electronic: high-voltage battery cooling fan control, 12V battery drain, and software glitches. With regular software updates and attention to the 12V battery, the system can be very reliable. The high-voltage battery is warrantied for 10 years/160,000 km in many markets.
The most frequent issues are high-voltage battery cooling fan failures, 12V auxiliary battery drain (especially when parked), software glitches in the hybrid control modules, and electric motor position sensor faults. These are well-documented in Stellantis service bulletins and owner reports.
The eFlite powertrain is used exclusively in the Chrysler Pacifica Hybrid (2017–Present). It is not available in any other Chrysler, Dodge, Jeep, or Ram vehicle. It is the only plug-in hybrid minivan offered in North America and select other markets.
No, the eFlite system is not tunable in the traditional sense. The complex integration of the engine, electric motors, and control software makes aftermarket performance modifications extremely difficult and unsupported. Any attempts could compromise safety systems and void warranties.
Fuel economy is exceptional when utilizing the electric range. The EPA rates it at 82 MPGe combined. Once the 16 kWh battery is depleted, it operates as a hybrid, achieving around 8.0-8.5 L/100km (33-35 mpg UK). Real-world economy depends heavily on driving habits and how frequently the battery is recharged.
The internal combustion component (3.6L V6) of the eFlite system is an interference engine. If its timing chain were to fail, severe engine damage would occur. However, the timing chain is generally very reliable. The electric motors have no such mechanical interference risk.
The petrol engine requires 5W-20 engine oil meeting Chrysler specification MS-6395. The eFlite transaxle requires Chrysler ATF+4 automatic transmission fluid. Using incorrect fluids can damage components and affect hybrid system performance. Change intervals should be followed as per the owner's manual.
