Jeep Grand Cherokee 4xe Battery: Complete Guide
The Jeep Grand Cherokee 4xe has two batteries: a 17.3 kWh high-voltage pack mounted under the floor, which drives it 26 miles on electricity alone, and a conventional 12-volt battery under the spare tire in the rear, which runs the electronics and causes most of the battery problems owners actually meet. Together with the 2.0L turbocharged engine, the plug-in hybrid system makes 375 horsepower and 470 lb-ft of torque, covers about 470 miles in total, and returns 56 MPGe.
Jeep sold the Grand Cherokee 4xe from 2022 to 2025; it was discontinued for 2026 when Stellantis ended its North American plug-in hybrid models. A Level 2 charger refills the pack in about 2 to 3 hours, and there is no DC fast charging. The high-voltage battery and drivetrain are shared with the Wrangler 4xe.
Quick answer
The Grand Cherokee 4xe’s high-voltage battery is a 17.3 kWh NMC pack (~15 kWh usable) under the floor, good for 26 miles of electric driving. Its separate 12-volt AGM battery sits under the spare tire in the rear. High-voltage replacements are rare — most owners pay $0 under warranty or the fire-recall programme; an out-of-warranty dealer replacement typically runs about $8,000–$12,000 fitted.
Key figures: 17.3 kWh (~15 usable) · 26 miles EPA electric · 470 miles total · 56 MPGe · Level 2 ~2–3 hours · Warranty 8 years/100,000 miles (10 years/150,000 miles in CARB states)
The system produces 375 horsepower and 470 lb-ft of torque, which makes this the quickest Grand Cherokee ever made. A Level 2 charger fills the battery in about 2.5 hours. Because the battery is small and charges quickly, the vehicle does not use DC fast charging. Jeep uses the same battery and drivetrain design for both the Grand Cherokee 4xe and the Wrangler 4xe.

Grand Cherokee 4xe vs. Wrangler 4xe Comparison
The Grand Cherokee 4xe and Wrangler 4xe use the same 17.3 kWh (kilowatt-hour) battery and 375-horsepower hybrid system. This battery is the unit that stores electricity for the vehicle. The Grand Cherokee travels 25 to 26 miles on electricity, while the Wrangler travels 21 miles. Better aerodynamics help the Grand Cherokee gain extra electric range from the same battery. The Grand Cherokee also features air suspension, more back seat legroom, and a quieter ride on highways.
The Grand Cherokee 4xe is a luxury SUV for five people, unlike the off-road Wrangler. It suits drivers who need a daily vehicle with good electric range for commuting and gas power for long trips. The 4xe model costs about $5,000 to $7,000 more than a standard gas Grand Cherokee. Most drivers who commute less than 25 miles per day on electricity alone will save enough on fuel to cover this extra cost.
How the PHEV System Works
The Grand Cherokee 4xe combines a 2.0L turbo engine with two electric motors and an 8-speed automatic transmission. In Electric mode, the vehicle turns off the gas engine. Both electric motors then power the Quadra-Drive II 4WD system.
In Hybrid mode, the car combines engine power with motor power to save fuel, achieving 56 MPGe. The eSave mode saves battery charge for later use. Drivers can use this to save electric power for city driving at the end of a long highway trip.
Grand Cherokee 4xe Charging
Method | Power | 17.3 kWh (Grand Cherokee 4xe) |
|---|---|---|
Level 1 (120V standard outlet) | ~1.2 kW | ~12 hours full |
Level 2 (240V, 7.2 kW) | 7.2 kW | ~2.5 hours full |
DC Fast Charge | Not supported | N/A |
You can easily start each day with a full battery by charging for 2.5 hours on a Level 2 charger. If you plug into a Level 2 station at work for an 8-hour shift, you will charge the battery twice.
This vehicle does not have DC fast charging, but that is not a problem. Since the battery is small, Level 2 charging meets all your daily needs. You can even plug in for 30 minutes to add about 7-10 miles of range for quick errands.
EV Range in Real-World Conditions
- Mild weather, urban driving: 22–27 miles EV-only — consistent with the 25–26 mile EPA rating at low urban speeds
- Highway at 65–70 mph: Approximately 18–22 miles EV-only — aerodynamic drag at speed reduces electric efficiency
- Cold weather (below 0°C): Approximately 15–20 miles EV-only — battery heating draws from the pack significantly
- Cars.com cold-weather test: 81% of predicted 27 miles achieved in cold conditions — approximately 22 miles real-world in a full winter test
The Jeep Grand Cherokee 4xe Off-Road Performance
The 4xe system adds about 600 pounds to the Grand Cherokee compared to the V6 model. This weight increase is small compared to the improved performance and electric driving range you gain. Electric motors provide instant torque, which is the twisting power that helps wheels turn. This makes rock crawling and controlling the vehicle on trails much easier than with a standard gas engine at low speeds.
The Trailhawk 4xe trim is built for tough off-road adventures. It includes a 2-inch lift to raise the vehicle higher off the ground and a special Quadra-Lift air suspension system. These features help the vehicle earn its Trail Rated certification, proving it can handle difficult paths.
Grand Cherokee 4xe Battery Warranty and Longevity
Stellantis covers the Grand Cherokee 4xe battery with an 8-year or 100,000-mile warranty. This warranty protects you against defects, and if the battery loses more than 30% of its capacity. In CARB (emissions) states the coverage runs longer: 10 years or 150,000 miles.
No large independent study has measured Grand Cherokee 4xe degradation, so be wary of precise yearly percentages quoted elsewhere. What is known: the pack only works through about 15 of its 17.3 kWh, and that built-in buffer, plus the shallow daily cycling of a plug-in hybrid, is gentle on the NMC cells. The warranty floor — replacement if capacity falls more than 30% — is the protection that matters in practice.
Grand Cherokee 4xe Battery Recalls
Two fire recalls cover this battery, both caused by damage inside the Samsung SDI cells that can lead to a fire even while the vehicle is parked and off. Recall 95B (2024) covers 2022–2024 models.
The larger recall 68C (2025) covers 2022–2026 Grand Cherokee 4xe vehicles — its remedy is a software update that watches for the fault, warns the driver and disables charging, with the battery pack replaced free if the fault is found. Owners who complete the 68C remedy also receive lifetime, unlimited-mileage high-voltage battery coverage under Jeep’s XU1 extension. Check your VIN free at nhtsa.gov/recalls before buying or charging a used example.
Grand Cherokee 4xe Battery Replacement Cost
Most owners will never pay for this battery: failures inside 8 years/100,000 miles (10 years/150,000 in CARB states) are a warranty claim, recall remedies are free, and the XU1 lifetime extension covers packs that have had the 68C fix. If a pack does fail out of warranty, there is no official Jeep list price for owners; the Mopar pack lists at roughly $15,000 as a part, and dealer-fitted replacements are commonly quoted at about $8,000–$12,000 including labor. Get the warranty and recall status checked first — on this vehicle, the free routes cover almost every realistic failure.

The Grand Cherokee 4xe 12-Volt Battery
Alongside the high-voltage pack, every Grand Cherokee 4xe has a conventional 12-volt AGM battery — and unlike its Wrangler 4xe sibling, whose 12-volt battery sits under the hood, the Grand Cherokee’s is in the rear of the vehicle, underneath the spare tire (Jeep’s owner’s manual wording). It powers the electronics, and the hybrid system wakes about every three weeks to top it up from the high-voltage battery while that battery holds charge above its minimum.
Expect about 3 to 5 years of life; premature drain is a widely reported owner complaint, and a tired 12-volt battery is the first suspect for no-starts and electrical glitches. Replacement is a sub-hour job — dealers run 12-volt service specials from about $263 — and the size depends on equipment (H6 without the tow package, H7 with it), so confirm by VIN before buying one.
Charging Tips for Grand Cherokee 4xe Owners
- Install a Level 2 charger at home: The 2-to-3-hour charge fits easily into any evening routine — a Level 2 charger is the single most impactful upgrade for 4xe ownership
- Use eSave on highway segments: Activating eSave before long highway stretches preserves full battery charge for urban sections where EV-only mode saves the most fuel
- Use departure scheduling: The Uconnect app allows scheduling charge completion just before departure, which avoids the battery sitting at 100% for extended periods
- Use Electric mode around town daily: Drivers commuting under 25 miles can cover their entire daily journey on electricity — eliminating gasoline use completely on typical weekdays
