When your Jeep 4xe is not charging and you’re stuck without a ride to work, it’s beyond frustrating. Your Jeep becomes a giant paperweight, especially when the battery is super low or completely dead. The charge indicator on the panel might be acting up, showing problems, or nothing at all.

In our recent post on the best Jeep 4xe chargers, we tried and tested the top ones on the market. We put the #1 Grizzl-E Level 2 EV Charger, #2 JuiceBox 40 Smart Charger, #3 ChargePoint Home Flex Charger, and #4 MUSTART Level 2 Portable EV Charger to the test. If you’re still deciding which one is the champ, you can check out more details here.

Now, if you’ve got one of the chargers we recommended or you’re using the original Jeep charger and your 4xe is still not charging or it suddenly stopped working, don’t panic. We’ve dug into some common issues causing your Jeep 4xe to resist charging, and we’ve got solutions to help you get it back on track.

When your 4xe refuses to charge, there are three main suspects: first up is the power source, then your Jeep 4xe charger, and lastly, the charging system in your Jeep. Let’s figure out what’s causing the hiccup and get you back on the road!

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 you stick the charging head into your Jeep 4xe at the wrong angle, and the con pin connector doesn’t connect right, your Jeep won’t charge. In our tests with different EV chargers, we noticed that Jeep’s charging hardware and software don’t handle charging errors well, like incorrect supply specs, voltage issues, or wonky waveforms. All of these can happen if you don’t plug in your Jeep 4xe charging head correctly.

The fix is pretty straightforward. Just start the charging process again. Take out the Jeep 4xe charging head, close the charging hatch, and give it another shot. If that doesn’t do the trick, there might be dirt or debris in the charging port messing things up. Check the port and the Jeep 4xe charging head, clean them up, and try again. And if none of these solutions work, a good old restart of your Jeep 4xe might just do the magic.

NEMA Plug-Sharing Circuit Breaker With Other Devices

Another common issue is when your Jeep 4xe charger shares the electrical line with other devices. If your circuit breaker trips while charging, it could mean the connection is overloaded. Watch out for your charging head getting too hot or yellow lights blinking on the EVSE—that’s a sign of grounding or overheating issues.

Because of this, your Jeep 4xe might start and stop charging or just stop altogether. To fix this, check if your charger’s power rating matches or is higher than the breaker capacity. We recommend a 50A 220V breaker for a level 2 charger.

If you share a circuit breaker, it’s better to use the Grizzl-E with its dedicated 50A 240v breaker. Ensure the wires are the right size (40-50amps load) and connect it to a 240V 40amp outlet for smooth charging.

We use an outlet tester to make sure your outlet and wiring are working properly. It’s a simple tool to ensure everything’s in order:

Random voltage spikes or drops when charging your Jeep 4xe

Here’s another common issue: voltage going up and down when you charge your Jeep 4xe. First, use a tool like Kill-A-Watt to check how much power your home Jeep 4xe charger is using.

If you notice voltage spikes or drops, you might see error codes like P0D-27, telling you there’s a problem. Some codes include High Voltage System Interlock Circuit A (P0A0A), Implausible Data Received from TCM (U0402), and HVIL Circuit Low (P0A0A, P1E73, and P1E74).

How to fix it? Check the voltage and make sure it’s stable, especially if you’re using a Jeep charger extension cord. If it’s not right, talk to your utility company.

If your Jeep shows error codes, you’ll need to clear them with an OBD2 scanner. We like the OBDLink MX+ for its compatibility with the 4xe, making it easy to figure out what’s wrong.

To avoid these problems and keep your Jeep 4xe charger and Jeep 4xe safe from low voltage, add a portable RV surge protector. We recommend Progressive Industries RV Surge Protectors; they come in 50amps and 30amps, depending on your Jeep 4xe charger (level 1 or 2).

A surge protector is super important to avoid big repair costs. Progressive Industries RV Surge Protectors keep your Jeep 4xe charging system safe from voltage changes, power surges, and weird shore powers that could mess up your charger, charging system, and other Jeep 4xe gadgets.

Problem with your Jeep 4xe Charger

Your Jeep 4xe Charger might act up, refusing to charge or acting all wonky. It happens when parts wear out, there are manufacturing glitches, or nature decides to throw a curveball. A glitchy charger may show signs like weak power, sporadic charging, or playing hide-and-seek with connectivity.

We went on a mission, testing 10 Jeep 4xe chargers to find the best level 2 charger for your ride. Guess what? Only three chargers stole the show: Grizzl-E Level 2 EV Charger, Home Flex Charger, and Juicebox 40 Smart Chargers. These are the real MVPs. The other seven? Well, they didn’t make the cut. They either had issues or sported designs that could make your Jeep 4xe throw a charging tantrum.

Now, let’s spill the beans on what went wrong with those seven chargers. Their flaws? Blame it on the not-so-great design of the EV charging hardware and the software platforms (charger network operators). It’s like a teamwork fail that messes with your Jeep’s charging mojo.

Hardware Challenges in Jeep 4xe Charging

In our test of Jeep 4xe chargers, some of them flunked, refusing to juice up our ride. We chalked it up to a mix of shoddy design and low-quality parts in the charger. The result? Loose connections that played hard to get. Problematic parts included the charging ports, buttons, wiring, and screens that turned a bit lazy.

Materials used in aftermarket Jeep 4xe chargers varied. If your charger throws a fit in extreme weather think heatwaves, chilly days, or wild storms you might want to check for culprits. Poorly designed chargers without weatherproof bits and a strong electrical system could be the troublemakers. Look out for weather-ready chargers with a sturdy electrical system that can handle the ups and downs of Mother Nature.

Loose connections love poorly designed Jeep 4xe chargers. The quality of charger components plays a role too, affecting how well your Jeep 4xe charger behaves. In our test, some chargers struggled in scorching heat, leading to sluggish charging, damage to electronic bits, and extra power needed for AC, causing a strain that messes with your electrical supply. Result? Your Jeep 4xe charger might throw a fit, refusing to charge, playing hide-and-seek, or constantly disconnecting.

Cold temps weren’t a breeze either. Chargers with poorly designed bits for the chill, like good insulation and heating systems, struggled. No charging, lower efficiency, and internal resistance creeped up as the Jeep 4xe charger fought the cold using its AC system. And here’s a chill fact: some cables got temporarily stiff, brittle, and cranky, even cracking or breaking, messing with the electricity flow.  

Software Challenges in Jeep 4xe Charging

Software issues could be the sneaky reason your Jeep 4xe charger is acting up. Our top-notch chargers have fewer hiccups in the software department. They get regular updates, fixing bugs and making the chargers more reliable. How? By dealing with potential software problems, using common communication protocols to work well with the Jeep 4xe charging system, and adding security measures to keep unwanted guests away.

Now, the chargers that stumbled over software bugs? They had trouble communicating with the Jeep 4xe, leading to charging issues. Imagine problems like incorrect charging monitoring, billing glitches, and service denial with wrong charges. No one wants that drama.

So, if your Jeep 4xe charger is misbehaving, software problems might be the sneaky culprit. Choose a charger that’s on top of its software game for a smoother charging experience.

4xe Will Not Charge Through Plug, E Save still works

Your experience with the early 4xe seems like quite the journey. Initially facing check engine light issues and undergoing battery harness replacement, it seemed to stabilize post updates/recalls, charging properly at most level 2 chargers.

However, coincidentally at 10,000 miles, the first oil change warning lights appeared, and the car abruptly stopped charging at level 1 and 2 chargers, consistently displaying an immediate fault upon plugging in, including with the Mopar charger checked at the dealer. E Save mode still functions but takes notably longer to charge the battery. You’ve tried starting the charge at 20-30% battery, but the issue persists.

You have a service appointment next week, aiming to address this sudden halt in charging after thousands of miles of trouble-free operation. You’re curious about others’ experiences with charging system errors, as yours seems unique—a sudden stop after a lengthy period of normal function. Interestingly, the engine still charges the battery in E Save mode, and you’ve noticed better battery performance during rush hour traffic in this mode.

You plan to share the findings post-service appointment. You’ve examined the charging plug and the area around the removed back seat, which has been out since the car’s beginning and doesn’t show visible damage. However, there’s a slight concern that the dealership might attribute the removed seat to potential battery issues, though it has been in this state since the car’s inception.
