Top Reasons Why Hyundai iONIQ 5 Not Charging and How to Fix?

How to Fix Hyundai iONIQ 5 Not Charging

While electric cars are less expensive, you must manage their charging carefully. If you want to travel or have longer commutes frequently, you should arrange the charging station stops carefully. You must look for alternatives if the car is away from the home charging station. However, a problem arises when the vehicle does not charge, regardless of the station.

Although electric cars are a great option for purchasing an economical and less maintained vehicle, the charging issues might be annoying, especially when the vehicle stops because of a charging problem. Identifying the cause of these issues is important as they can occur anywhere. To take care of your Hyundai iONIQ 5, you should disconnect it from the wall outlet when you are not using it. This will save energy and improve the battery life of the car.

Below, you will find some common charging issues with the Hyundai iONIQ 5 and how to fix them.

Check Cable Connection

The most common reason the charger won’t work is that it’s not properly connected to the car. If this is the case, connect the charger properly with the correct cable and plug it into the outlet. Check that the cable is fully plugged in at both ends. If the charging cords or plugs are frayed or broken, replace them as soon as possible to prevent internal damage to the electric car.

Don’t Use an Extension Cable

When you are at your home charging point, you might want to use an extension cable to charge your vehicle from a bit farther away. However, this might push more current than an extension cable can use. To fix this, push your car closer to your home charger. If you move your car to the charging point, you won’t need the extension. The long-term solution is to relocate the charger so the standard cable reaches your car. Otherwise, you can also purchase longer cables, which can be safer and more reliable.

Check Battery

Car chargers may also not charge if there is a problem with the battery itself. Take the battery in for service or replace it, as there might be a chance it isn’t functioning properly.

Check Power Levels of Car

Cars can run out of power and stop charging. Some components of the car will need to use power even when it is switched off. In these cases, it is necessary to plug in the car and turn on the switch next to the battery to recharge it.

Inversely, if the car is already charged, it stops the charger to prevent waste. You can use the Hyundai iONIQ 5 to check the current battery level of your car. If it is fully charged or even close enough, the charge point might switch off automatically to preserve electricity and your car’s battery life.

When you are in public, the charging points are much more likely to stop charging when your car charge reaches 80%. This is mainly for the free stations, where there are built-in safety features to prevent over-charging as well as electricity wastage.

Disable In-Car Delay Timer

The Hyundai iONIQ 5 might have a delay time schedule set, which is why it doesn’t take charge. Disable the schedule to be able to charge your vehicle again. To charge outside your normal schedule, switch off the car and press the timer override button.

Disable Smart Charging

It is often possible to set a specific charging time through an app, causing the charging to be delayed until later. To disable smart charging, go to the settings page and tap “Save.” Tap “Boost” if you need to begin charging right away. Note that it may take a minute for the charge point to respond.

Verify Payment and RFID Card

You will need to use a service charge point if you are not at your home station. In the case of your car not charging, you can verify the payment for the charge point via the Hyundai iONIQ 5 app. Some stations are free, but most are not, especially at retail parks and petrol stations. If you need an RFID card to make the payment, check your information to see if everything is correct. These are Radio Frequency Identification cards, which you can use to top-up your EV with funds for charging.

Check Connector

You might use a different connector at a public charging station without knowing it. This is because not all electric cars use the same connector. Make sure that the one you are using is compatible with your Hyundai iONIQ 5. EV charging infrastructure might also differ based on the public charging stations, as some stations offer rapid chargers.

Change Public Pod

Sometimes, the pod point at the motorway service station might be at fault. These encounter heavy use daily, and sometimes they stop working when not attended to. You can try running a diagnostic through the app, and check the problem. If it persists, try to contact the pod point owner or operator. And, of course, change to a different pod point.

Contact Support

Sometimes, the problem might run deep and be too serious. If none of these fixes works, you can contact your car manufacturer or dealer for more support.

The Hyundai iONIQ 5 is a great choice for the environment and your bank account in the long run. Charging them is cheaper compared to refuelling a vehicle. Once you have addressed the issues related to charging your electric vehicle, you should be good to go. Usually, these cars do not require much regular maintenance or repairs.


  1. I wish that was the case, contact your dealer and all will be good, I booked a 4th service appt to fix my never did fast DC charging issue since I tested it about 3 weeks after owning (Late Oct 2022 delivery). First fix was we need to change the CCS / J1772 socket wiring harness as we think it is one of the DC high voltage pin temperature sensors, 7 weeks later that part showed up, 4 weeks later the appointment to change it out, That did not work. So service adviser contacted Hyundai and 1 week later after multiple calls he told me we can fit you in in 4 weeks to perform more diagnoses with Hyundai Corporate tech support, I said no can you do better they move it one week closer. Should have bought a Tesla at least they know their Tech!

  2. Here is my Hyundai iONIC 5 story in Rotterdam! MY Hyundai ionic 5 suddenly stop charging after 1 year 3 months, the dealer said something is wrong with computer/chip, they have to order the new chip. After one month, I still did not get my car back because the dealer also don’t know when the chip can be delivered. During that month, I did not receive any phone call from the dealer unless I called them for check the situation. I contact Hyundai Nethelands if someone can help me because I really need to drive my kids everyday to training and to school. We’re having already a lot of trouble in this month and now we still don’t know when my car can be fixed en returned. So I asked dealer can I have a replacement car, the dealer answered : You need to pay for the replacement car everyday 50 euro. I am very disappoint with Hyundai service!
