The Chrysler eFlite PHEV powertrain is used exclusively in the Chrysler Pacifica Hybrid with transverse mounting. This system received minor software updates across model years but no major hardware revisions, ensuring broad parts compatibility. All adaptations and calibrations are documented in OEM technical bulletins.
The eFlite PHEV's primary operational characteristic is transition behavior between power sources, with documented calibration refinements in early models. Stellantis TSB 18-076-22 addresses software-related shift quality, while real-world owner reports highlight sensitivity to charging habits. Maintaining regular charging cycles and applying the latest software updates are critical for optimal performance.
Analysis derived from Stellantis technical bulletins (2021-2024) and NHTSA owner complaint data (2021-2023). 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 PHEV powertrain is generally reliable, leveraging proven components from Stellantis' hybrid portfolio. The petrol engine is robust, and the battery comes with an 8-year/100,000-mile warranty. Long-term reliability depends heavily on regular charging and adherence to software updates. Early software-related transition issues were largely resolved via TSB 18-076-22.
The most common issues are rough transitions between power modes (addressed by TSB 18-076-22), reduced electric range in extreme temperatures, 12V battery drain when parked, and occasional cooling pump failures. These are well-documented in Stellantis service bulletins and owner forums. High-voltage component failures are rare.
The eFlite PHEV is used exclusively in the Chrysler Pacifica Hybrid minivan, available from the 2021 model year onwards. It is offered in Touring L and Limited trim levels. No other Chrysler, Dodge, Jeep, or Ram vehicles currently use this specific eFlite PHEV configuration.
Tuning potential is extremely limited. The system is highly integrated, and modifying software or hardware can void warranties and compromise safety. No reputable tuners offer performance upgrades for the eFlite PHEV. Focus is on efficiency, not power enhancement. Any modifications are strongly discouraged.
When fully charged, it achieves 82 MPGe (miles per gallon equivalent). Once the electric range is depleted, it operates as a conventional hybrid, returning approximately 30 mpg combined. Real-world economy varies significantly based on charging frequency; drivers who charge daily can achieve over 100 MPGe, while those who rarely charge may see figures closer to 25-28 mpg.
Yes, the 2.0L turbocharged petrol engine within the eFlite PHEV system is an interference design. If the timing chain were to fail, piston-to-valve contact would occur, causing severe engine damage. However, the timing chain is very durable and rarely fails with proper maintenance using the correct 0W-20 oil.
The petrol engine requires MOPAR SAE 0W-20 engine oil meeting specification MS-6395. This low-viscosity oil is critical for the Atkinson-cycle engine’s efficiency and the overall hybrid system’s performance. Using the correct oil and changing it every 10,000 miles (or 12 months) is essential for engine health and fuel economy.
