"Electric Mode Temporarily Unavailable, Fuel and Oil Refresh in Progress" Issue in Jeep

Jeep 4xe vehicles are powerful SUVs powered by potent electric motors and gasoline engines. This means that even when your gas tank runs dry, you can drive using the electric motors for as far as 21 miles.

If you activate the electric mode, you can drive with zero emissions. The EV mode allows you to go wherever you want without range anxiety. The Jeep Wrangler, for instance, has a driving range of 21 miles in electric mode. This means you can drive for quite a long time without needing the gasoline engine.

Why my Jeep Says "Electric Mode Temporarily Unavailable"

The following are a few reasons your Jeep says "Electric Mode Temporarily Unavailable."

1) Outside Environment Colder than Inside Environment

The primary reason someone buys one of the Jeep 4xe models, such as the Wrangler 4xe, is the highly praised hybrid capabilities. The Wrangler 4xe features an electric-only driving range of 21 miles. Imagine paying $56,000, and your machine refuses to engage the EV-only mode when winter arrives.

Unfortunately, many owners have testified that once the outside environment gets colder than the inside, the gas engine takes over and disables the electric mode for several miles. The 2.0L DOHC direct-injection Turbo I4 engine cannot keep up with your driving desires without the hybrid capabilities.

In this state, the vehicle displays the "Electric Mode, Temporarily Unavailable" message on the cluster panel. Without the EV mode, your Jeep Wrangler achieves 20 mpg at best. Other conditions that disable the EV mode in your Jeep include starting your vehicle in cold temperatures.

If the outside temperature drops below 15 degrees Fahrenheit, the cabin is less efficient, causing the gas engine to take over, disabling the EV mode.

2) Overheating High Voltage Battery and Related Components

According to a recent recall involving 13,722 Jeep Wrangler 4xe Plug-in models, some Jeep hybrid vehicles have a bad fuse fastener in the battery pack. The faulty fastener causes the high-voltage battery, conductors, and motors to overheat, causing the vehicle to lose its hybrid properties. Your vehicle's ECU disables the EV mode to protect the battery and related components from further damage.

The faulty fasteners hold the 200-amp fuse in the Battery Park. When the fastener fails, your vehicle loses its hybrid capabilities, not just temporarily, as the warning indicates. You will have to replace the burned fuse to restore the hybrid capabilities of your Jeep.

According to Jeep and Stellantis, Jeep's mother company, when this problem arises, you may hear disturbing noises from the battery pack and a change in drivability. A warning light and the "Electric Mode Temporarily Unavailable" will follow these symptoms.

The good news is that Jeep has a solution to this problem. When you take your vehicle for inspection and they notice your faulty fastener, the company replaces it free of charge. Jeep will also replace the entire Battery Park if they notice any discoloration. Additionally, if you had made any repairs to rectify this problem before Jeep issued the recall, the company promises to reimburse you to the last dollar.

3) Driving Modes

Jeep created the 4xe models with several driving modes, including hybrid, electric, and e-save. Your cluster panel could display the Electric Mode Temporarily Unavailable" depending on your driving mode.

For example, if you switch to engage the 4xe eSave Mode, your ECU deactivates the electric mode and employs the gasoline engine only. You can switch to this mode when you want to save the battery charge or when you realize it is going down.

This mode utilizes regenerative braking technology to charge the battery when your brake pedal is at a low position. Your Jeep has a feature that uses maximum regeneration to escalate battery revitalization when you brake or decelerate.

If you activated the eSave mode because of a low battery charge, you could reengage the electric mode as soon as you recharge your battery pack at home or on the go at a charging point.

Why My Jeep Says "Electric Mode Temporarily Unavailable, Fuel and Oil Refresh in Progress"

The Jeep Wrangler, the most popular Jeep 4xe model, has an electric-only driving range of 21 miles. This is enough mileage to run a day before recharging the battery overnight in readiness for the next day. This means you can drive long without engaging the gasoline engine.

When you drive for an extended period on electric-only mode, your gas can become stale after sitting in the gas tank for too long. The engine oil could also lose its lubricating properties. To protect your engine and fuel delivery system from damage due to stale gas, your Jeep has a Fuel and Oil Refresh mode. This mode also helps your oil restore its lubrication properties to protect your engine's internal components.

Your Jeep enters into a Fuel and Oil Refresh Mode automatically to keep your fuel from turning stale and to ensure proper lubrication of your engine's internals.

The gas engine only operation....

While in the Fuel and Oil Refresh Mode, the gasoline engine keeps running to propel your vehicle. A message will appear on the cluster panel saying, "Electric Mode Temporarily Unavailable, Fuel and Oil Refresh in Progress." When the Fuel and Oil Refresh operation is complete, it will exit automatically and restore the hybrid properties of your Jeep.

Stale Fuel....

If your vehicle initiates the Fuel and Oil Refresh mode due to stale fuel that has sat in the gas tank for an extended period, the gas engine will run without the electric mode until your ECU activates the low fuel warning. You can exit the Fuel and Oil Refresh Mode by toping your gas tank with at least four gallons of fresh fuel.

Lack of Lubrication....

If your vehicle initiates the Fuel and Oil Refresh Mode because your engine oil lost its lubrication qualities, adding fuel will not restore the oil properties and will not exit this mode sooner. The Jeep will run for at least 20 minutes after the engine attains its optimal operating temperature without the electric mode.

If you switch off your engine before the ECU confirms oil quality satisfaction, the process will restart when you turn the engine on again. The process will continue until it achieves the required engine oil standards.

Frequent short trips will most likely trigger the Fuel and Oil Refresh mode, consequently triggering the "Electric Mode Temporarily Unavailable, Fuel and Oil Refresh in Progress." This happens mostly with vehicles in cold regions.

The other driving modes available in Jeep 4xe models

• 4xe Hybrid Mode

The Jeep 4xe hybrid mode combines gas and electric motors. This mode draws power from the turbocharged 2.0L engine and the electric motors to give your Jeep the best horsepower and torque outputs.

While in the hybrid mode, your vehicle uses electric power first, followed by gasoline. While in this mode, your Jeep can achieve an average MPG of 49 and 56. The variation comes from the different models of Jeep 4xe.

• 4xe Electric Mode

When cruising through the city streets with your Jeep, you can activate the 4xe electric mode. In this mode, your vehicle uses battery power only and delivers near-100 percent zero emissions. You can activate the electric-only mode if your Jeep has a charge of at least one percent.

You can enjoy a quiet ride in your all-electric mode for up to 21 miles on the Jeep Wrangler 4xe or 25 miles on the Jeep Grand Cherokee 4xe. This mode bypasses the gasoline engine completely.
