System Shutdown Patterns
Battery system shutdowns happen more in the cold. Many owners deal with what Jeep calls the “Fuel and Oil Refresh Mode” (FORM). This mode can last a long time, making electric-only driving hard to do in winter.
Cold Weather Operating Limitations
The Jeep 4xe has big limits in cold weather. Drivers say they can’t drive electric-only in winter. This goes against the car’s promise of a 21-mile electric range.
Maintaining oil temperature around 192 degrees is key for good performance in the cold.
Engine Performance and Power Loss Concerns
Jeep 4xe owners have faced big engine problems. These issues make them question the car’s reliability. The plug-in hybrid system, though new, has shown many problems with power and engine work. Jeep 4xe problems often show up as sudden power loss and performance drops.
The engine problems come from several places:
- High-voltage battery system issues
- Electrical system problems
- Challenges with the hybrid powertrain
- Failures in sensors and diagnostic systems
Signs of engine trouble include:
- Sudden power drop while driving
- Unexpected engine stalling
- Rough idling and uneven acceleration
- Check engine lights turning on
| Issue Type | Potential Causes | Frequency |
|---|---|---|
| Power Loss | Battery Voltage Irregularities | High |
| Engine Misfire | Sensor Failures | Medium |
| Stalling | Electrical System Disruptions | Low-Medium |
Over 2,500 Wrangler 4xe models made between January and September 2022 had recalls. The main worry is about the 200-amp fuse. If it’s not fixed right, it could cause total power loss.
Vehicle owners should stay alert and fix any performance issues fast. This is to keep everyone safe and avoid long-term damage.
Transmission and Drivetrain Complications
Jeep 4xe owners face big problems with the transmission. The hybrid powertrain is complex, making it hard to deliver power smoothly. This affects the car’s performance and reliability.

Transmission Slipping Issues
Drivers often notice the transmission slipping, mainly when switching between electric and gasoline power. This can happen during hybrid mode transitions. It’s a safety concern and makes drivers less confident.
Drivetrain Vibrations
There are unusual vibrations in the drivetrain, seen in different situations. These problems often happen during:
- Low-speed maneuvers
- Sudden acceleration
- Electric-to-gasoline mode transitions
Power Delivery Problems
The hybrid system’s design can cause power delivery issues. With 375 horsepower and 470 lb-ft of torque, the Jeep 4xe’s performance is sometimes affected by these problems.
The integration of hybrid technologies requires meticulous calibration to ensure seamless power management.
