When charging your Jeep 4xe is the only way to get to work. Your Jeep 4xe is not charging, you are in one of the most frustrating situations where your Jeep is just a massive paperweight when the battery is below 1% or dead, and the panel state of charge indicator indicates problems with charging or nothing at all.

In our last post about the best Jeep 4xe chargers, we spent time testing and reviewing the top chargers available in the market today, including the #1 Grizzl-E Level 2 EV Charger, #2 JuiceBox 40 Smart charger, #3 ChargePoint Home Flex charger, and the #4 MUSTART Level 2 Portable EV Charger all of which we had purchased for the purpose on testing which one amongst the four chargers is the best if you are still wondering which is the best one read more here.

If you have purchased the Jeep smart chargers we recommended or using the charger that came with your Jeep and your Jeep 4xe is not charging, or have been using your Jeep 4xe charger for a while. Suddenly your Jeep 4xe is not charging, so don’t worry; we have analyzed some common problems that will lead to your Jeep 4xe not charging and some of the solutions we have to help you fix your Jeep 4xe not charging.

If your Jeep 4xe is not charging, there are three main culprits; the first common one is the source of your electricity, followed by your Jeep 4xe charger, and finally, your Jeep 4xe charging system.

Jeep 4xe is not Charging – Check these first!

Here are some of the most common problems to help you diagnose your issue.

Incorrect insertion of the Jeep 4xe charging head.

When the charging head is inserted at the incorrect angle, and the con pin connecter is not making proper contact, then your Jeep 4xe will not charge; when testing various EV chargers, we found that Jeep hardware and software for charging have a low tolerance to errors during charging such as spec supply, voltage, waveform, etc. which might be impacted by not correctly inserting your Jeep 4xe charging head.

Close-up of Jeep 4xe charging port and charger connection that you need to check when your Jeep 4xe is not charging

The simple solution is to start the charging process again, remove the Jeep 4xe charging head from the port, close the charging hatch, and start the process again. If the first solution doesn’t work, you might have dirt or debris that might prevent current flow in the charging port. We recommend inspecting the charging port or the Jeep 4xe charging head for any debris and removing them; another standard solution after trying all three solutions is to try and restart the Jeep 4xe.

NEMA plug-sharing circuit breaker with other devices

Another common issue is that you might have other devices sharing the circuit breaker with your Jeep 4xe charger. Another standard diagnostic is if your circuit breaker trips when charging your Jeep 4xe, which might also mean your connection is overloaded. You might also notice that your charging head will start overheating, and flashing yellow lights will start blinking on the EVSE, which means there is a grounding or overheating fault.

For this reason, your Jeep 4xe might start and stop charging or completely stop charging; we recommend first making sure that your charge power rating matches or exceeds the breaker capacity; we recommend a 50A 220v breaker connected to a level 2 charger.

If you are sharing a circuit breaker, we recommend that we use the Grizzl-E with a dedicated 50A 240v breaker, with adequately sized wires rated 40-50amps load, connected to a 240V 40amp outlet, and the charger charges perfectly.

We use an outlet tester to make sure the outlet is fine, and there is the correct power supply to the Jeep 4xe charger; this is all the item you need to make sure your outlet and wiring connection is working as they should:

Random voltage spikes or drops when charging your Jeep 4xe.

Another common problem is voltage spikes or drops when charging your Jeep 4xe; we first recommend checking what voltage you are getting; we use a Kill-A-Watt and will let you know how much power is being used by your home Jeep 4xe charger.

Test your Jeep 4xe home charger voltage

Now if you have a problem with voltage spikes or drops, which frequently happens with home chargers, you might experience a family of error codes (P0D-27) with the Jeeps 4xe system trying to protect itself from charging issues that may arise due to spikes or drops of voltage, some of the error codes reported to us include High Voltage System Interlock Circuit A (P0A0A), Implausible Data Received from TCM (U0402), HVIL Circuit Low (P0A0A, P1E73, P1E74)

The solutions to these errors are first seeing what voltage you are getting and making sure there are no significant voltage spikes or drops occurring in your home charging system, especially if you are using a Jeep charger extension cord; if you have tested with a Kill-A-Watt and the voltage is out of specs, contact the utility company to address the issue.

If your Jeep has thrown some error codes during the incident, you will need to clear the codes yourself using an OBD2 Scanner; we use the OBDLink MX+ that can connect to your phone or tablet; we recommend it for its compatibility with the 4xe and many of its module which enhance diagnostic of Jeep 4xe issues.

To avoid such errors and protect your Jeep 4xe charger and Jeep 4xe from low voltage issues, we recommend adding a portable RV Surge protector to protect your Jeep 4xe against voltage fluctuations. We use Progressive Industries RV Surge Protectors available in 50amps and 30 amps depending on your Jeep 4xe charger, which might be a level 1 or 2 charger.

We highly do recommend a surge protector that will protect you from high repair and replacement costs of Jeep 4xe charging systems that voltage fluctuations can damage; the Progressive Industries RV Surge Protectors will protect your Jeep 4xe charging system against voltage fluctuations, power surges, and incorrectly wired shore powers which can cause dame to your Jeep 4xe charger, Jeep 4xe charging system and many other accessories in your Jeep 4xe set-up.

Problem with your Jeep 4xe Charger.

Like many other electronic devices, you might be experiencing problems with your Jeep 4xe Charger which might become unresponsive or malfunction, your Jeep 4xe might fail to charge if its components fail due to wear and tear, manufacturing defects, or environmental factors, a faulty Jeep 4xe charger might exhibit issues such as little or no power output, inconsistent charging or intermittent connectivity.

We bought 10 Jeep 4xe chargers and ranked them for our article that lists the best level 2 charger for Jeep 4xe, among the 10 Jeep 4xe chargers, only three chargers Grizzl-E Level 2 EV Charger, Home Flex Charger, and Juicebox 40 Smart Chargers won our hearts, the other 7 chargers we tested had problems or exhibited poor design or engineering that can cause or make them susceptible to a multitude of issues that will result in your Jeep 4xe not charging.

Some of the problems we discovered in the seven losing Jeep 4xe chargers we tested and excluded from our list of the best Jeep 4xe chargers are related to the poor design of the EV charging hardware and the software platforms (charger network operators) that all work jointly to charge your Jeep.

Hardware Challenges in Jeep 4xe Charging

During our Jeep 4xe charger test, some of the Jeep 4xe chargers failed to charge our Jeep 4xe, we attributed the hardware failure to poor design and component quality of the Jeep 4xe charger that resulted in loose connectivity, some of the components that were poorly designed and required quality components include charging ports since they are susceptible to damage or contamination with dirt, buttons, wiring system, and poor quality screens that became unresponsive.

We also noticed there were varying qualities of materials used to manufacture Aftermarket Jeep 4xe chargers if your Jeep 4xe charger refuses to charge during extreme weather conditions such as during heatwaves, high or low temperatures, rain, snow storms, and strong winds, it is important to check the culprit which includes poorly designed chargers that lack weatherproof components and robust electrical system, climate control systems such as ventilation, ventilation, and air conditioning (HVAC) systems, and weatherproof Charging Cables and Connectors. we recommend opting for a Jeep 4xe charger made from a weatherproof and robust electrical system that can withstand environmental fluctuations such as weather and temperature changes.

Poor designed Jeep 4xe chargers are easily affected by loose connectivity, while Jeep 4xe charger components quality affects the performance and usability of the Jeep 4xe charger, during our test we noticed some Jeep 4xe chargers when subjected to extreme heat can lower the efficiency of the charging process, and we experienced slow charging speeds, heat-related damage to sensitive electronic components, and increased energy demand required for air conditioning that causes strain to your electrical supply resulting to voltage fluctuations, that can result in your Jeep 4xe charger not charging, intermittent charging or the Jeep 4xe charger will keeps disconnecting.

We also tested chargers that did not charge our Jeep 4xe during cold temperatures, and we noticed that the chargers with poorly designed components for handling cold temperatures such as adequate insulation, and air conditioning (HVAC) systems experienced no charging, lower efficiencies, and increased internal resistance as the Jeep 4xe charger tries to warm itself using the air conditioning system, some other effects we noticed in cold temperatures were some cables temporarily become inflexible, stiff, brittle and inflexible to the point of cracking or breaking affecting the flow of electricity.

Software Challenges in Jeep 4xe Charging

Software problems might also be the reason why your Jeep 4xe charger is not charging, our best Jeep 4xe chargers had fewer software bugs and glitches, we noted these chargers receive regular software updates to improve their reliability and functionality of the chargers by mitigating potential software issues, utilize standardized and open communication protocols that improve compatibility between the Jeep 4xe charger and the Jeep 4xe charging system, and include some level of security measures to prevent unauthorized access to the charging station.

Jeep 4xe chargers that we experienced software bugs had poor communication protocols between the charger and the Jeep 4xe which resulted in the Jeep 4xe not charging, inaccurate charging Jeep 4xe charging monitoring, and billing and authentication issues that resulted in denial of services, and incorrect charges.

If your Jeep 4xe is not charging, there may be a problem with your Jeep 4xe charger, the charger you are using might not be supported. using the wrong connector or charger type on your Jeep 4xe might result in your Jeep not charging, We recommend matching the Type 1 or 2 charger type with the Jeep 4xe charging port to ensure compatibility

If you think your charging problem is emanating from your home charging set-up compatibility, we would recommend narrowing down the issue by trying to charge your Jeep outside of your home set-up; you can also contact the electrical contractor who installed the Jeep 4xe charger in your home for warranty services, which will identify issues with the charger set-up, and electricity issues.

Problems with your Jeep 4xe charging system.

Well, some Jeep 4XE owners realize they can’t charge their Jeep 4XE. On the infotainment system, there is an error saying “Service Charging System” The service charging system message is a message indicating that your Jeep 4xe charging system will need to be checked; it will prevent both level 1 and 2 chargers from charging your Jeep 4xe and also commercial charging stations will not work.

Common problems that we have found that occur before the error message is triggered include FORM, CHOC, and P0E15 issues, and you will need to check through an OBD2 reader to check what could be the problem and the exact error code triggered; we use the OBDLink MX+ in such situations, and mostly you will need to clear the codes errors or replace IDCM charging module, fuses, pins in the connector harness, etc.

If this error pops up, you will have to use the OBDLink MX+ or any other OB2 scanner to check what is triggering the Service Charging System error, common error codes you will get include P0D27-00 which means your Jeep Service Charging System error is triggered by a low voltage input code.

Jeep Service Charging System Error.

Some common issues on why your Jeep triggered a “Service Charging System Error” include hardware or software glitches in your Jeep 4xe charging system or your Jeep home charger is not installed properly and the error was tripped by a voltage imbalance when charging your Jeep.

How to Fix Jeep Service Charging System Error.

To fix the Jeep service charging system error you will need to clear error code IDCM P0D27-00 Battery Charger 1 Input Voltage Too Low error with an OBD2 scanner or visit your local Jeep dealership for a reprogram of your Integrated Dual Charging Module (IDCM) if your OBD2 scanner reports error codes B22A9-64, B22A9-16, B22A9-17, or B22A9-19 that cause the system to lock out the charging capability of your Jeep 4xe.

For IDCM P0D27-00 Battery Charger 1 Input Voltage Too Low error, you can clear the error code with your OBD2 scanner, Other error codes that might cause your Jeep 4xe not to charge and will require you to visit your local Jeep dealership include:

  • B22A9-64 – ECU Internal Performance-Signal Plausibility Failure.
  • B22A9-16 – ECU Internal Performance-Circuit Voltage Below Threshold.
  • B22A9-17 – ECU Internal Performance-Circuit Voltage Above Threshold.
  • B22A9-19 – ECU Internal Performance-Overcurrent.

The above codes will result in your Jeep 4xe not charging and require an Integrated Dual Charging Module (IDCM) Reprogram that takes approximately 0.3 hours to reprogram your IDCM at your local Jeep dealership.

If the Jeep Service Charging System Error was caused by a software glitch, you can use an OBD2 scanner to clear the error codes, however, if you have a hardware problem the error will not clear and will pop up after a few minutes indicating a damaged charging system component, we advise you at this stage to visit a Jeep dealership near you for a check-up if they can find and replace the component of the charging system that is damaged such as IDCM charging module, fuses, pins in the connector harness, etc

The problem doesn’t end there, we have found that most of the Jeep service charging system errors re-occur if the problem is not fixed at the root cause of the problem, We have had Jeeper reporting frequent visits to the Jeep dealership to have the codes cleared, this is because the error reoccurs after being triggered due to poorly installed, or wear and tear of your Jeep home charger installation, some common parts your electrician can inspect includes your Electrical Materials (outlets, wiring, breakers, panels, etc.), and also the components of your Jeep charger (power supply, charging cable, connector, control board, and the user interface)

If you are using commercial charging stations, note the charging stations you have visited in the past few days, and avoid them as they may trigger the service charging system error due to voltage imbalance, poor connectivity, faulty EV charging station, or power surge, we also recommend avoiding any related charging stations using the same chargers.

Final Thought.

Troubleshooting why a Jeep 4xe is not charging can be challenging; use the guides above to narrow down your problem, which might be classified into three categories, your home electric set-up, your Jeep 4xe charger, and your Jeep 4xe; however, it’s important to note that most issues are not easily disguised and troubleshooting the problem might need a check with your Jeep dealer, especially since you already have a Jeep warranty for such cases.

We highly recommend regularly checking and maintenance of your Jeep charger and its electrical connections to ensure they remain in good working condition, a good electrician will check for any signs of wear and tear in electrical connections including outlets, wiring, breakers, panels, etc. coupled with the diligent cleaning of connectors. your electrician will be able to recommend the frequency of your Jeep charger installation maintenance schedule.
