When MotorVero first reported on our long-term Jeep Grand Cherokee 4xe Trailhawk, we anticipated wrapping up our coverage with a standard sale process. However, an unexpected safety recall concerning the plug-in hybrid's battery system extended our time with this rugged SUV, providing valuable insights into modern vehicle recall procedures.
The Recall Notice: Understanding the Safety Concerns
The National Highway Traffic Safety Administration (NHTSA) issued recall notice 23V-XXX for certain Jeep Grand Cherokee 4xe models, citing potential fire risks associated with the high-voltage battery pack. The initial safety recommendation advised owners to:
- Keep the battery in a depleted state
- Avoid charging the vehicle
- Park away from structures and other vehicles
These precautionary measures significantly impacted our ability to use the 4xe as intended, essentially transforming our plug-in hybrid into a conventional gas-powered SUV until resolution.
The Recall Resolution Process
Step-by-Step Recall Remediation
1. Initial Diagnosis
After receiving the follow-up notice from Stellantis, we learned the fix required both a software update and comprehensive battery diagnostics. Unlike some over-the-air updates, this required dealership intervention.

2. Dealership Appointment
We scheduled service at an authorized Jeep dealership where technicians would first apply the software patch, then perform extensive battery testing. The process required:
- Full battery charge at the facility
- Multiple drive cycles for system monitoring
- Overnight (or longer) vehicle stay
3. Battery Health Assessment
The critical phase involved charging the battery to 100% capacity—something owners were previously instructed to avoid—then running diagnostic tests to evaluate:
- Cell voltage consistency
- Thermal management performance
- Overall battery degradation
Understanding the Technical Solution
The software update fundamentally changes how the battery management system (BMS) monitors and responds to potential fault conditions. According to technical service bulletins, the update enhances:
- Real-time cell voltage monitoring sensitivity
- Thermal runaway prevention protocols
- Early warning system for abnormal conditions
In cases where diagnostics revealed battery pack issues, complete replacement would be necessary. Fortunately, our 4xe's battery passed all evaluations, requiring only the software remedy.

Post-Recall Vehicle Performance
Since completing the recall work, we've observed:
- Restored full PHEV functionality with charging capability
- No noticeable change in electric range (still achieving ~25 miles EPA estimate)
- Unchanged charging times (~12 hours on 120V, ~2.5 hours on 240V)
The resolution has allowed us to properly evaluate the 4xe system as intended while giving us peace of mind regarding battery safety.
What This Means for 4xe Owners
Our experience provides several important takeaways for current and prospective Jeep 4xe owners:
- Recall responsiveness: Stellantis addressed this serious safety concern within months of identification
- Dealership preparedness: Service centers received clear protocols for diagnosis and repair
- No-cost resolution: As with all safety recalls, the repair was performed at no owner expense
- Transparency: Jeep provided regular updates throughout the recall process
For owners still awaiting recall completion, we recommend:
- Schedule service immediately at an authorized dealership
- Prepare for at least one overnight stay for your vehicle
- Request a loaner vehicle if available
- Verify completion with your recall notice closure

The Bigger Picture: Hybrid/Electric Vehicle Recalls
Our experience reflects broader trends in electrified vehicle maintenance:
- Software plays an increasingly critical role in vehicle safety
- Battery diagnostics require specialized equipment and training
- Recall processes differ significantly from conventional vehicles
- Manufacturers are rapidly evolving their service capabilities
As the automotive industry transitions toward electrification, both manufacturers and service networks must adapt to meet these new technical challenges while maintaining consumer confidence.
Looking Ahead: Final Impressions
With the recall resolved, we can finally proceed with our planned evaluation wrap-up. In our forthcoming comprehensive review, we'll cover:
- Real-world fuel economy in various driving conditions
- Long-term reliability observations
- Off-road capability assessment
- Total cost of ownership analysis
The recall experience, while unexpected, provided valuable insights into Jeep's handling of critical safety issues and the unique maintenance requirements of plug-in hybrid vehicles.
