10 Reasons Why Hyundai iONIQ 5 or 6 Won’t Start

The electric vehicle (EV) market is proliferating due to its reliability and low maintenance cost. The Hyundai iONIQ 5 / 6 are great electric vehicles that have just entered the market. These are fantastic options for individuals seeking an eco-friendly vehicle that provides excellent performance, comfort, and convenience. However, EVs can also experience issues like any fully-equipped electronic device. It should be no surprise that the Hyundai iONIQ 5 / 6 occasionally has issues preventing it from starting.

This article will discuss ten possible reasons why your Hyundai iONIQ 5 or 6 won’t start and what you can do about it. We will discuss common issues like low battery charge, faulty wiring, and more so you can quickly get your car back on the road.

1. Battery Overcharging

To start with, battery overcharging or poor charging habits can shorten the battery life of your EV and can even lead to your car not starting because of it. Don’t get me wrong; although most modern batteries are designed to withstand overcharging, this can still cause harm to your car’s battery. 

This can be a costly problem, as battery replacement and repairs can be expensive. Fortunately, there are several steps you can take to prevent this issue from happening in the future.

1. Check the Battery Voltage: The Hyundai iONIQ 5 and 6 both have a 12-volt battery. When the battery voltage drops below 12.0 volts, the vehicle may not start. To avoid this issue, drivers should check the battery voltage regularly and ensure it is at least 12 volts.

2. Avoid Overcharging: Overcharging the battery can cause serious damage and lead to the vehicle not starting. To prevent overcharging, ensure the charging system is turned off when the battery is fully charged. Additionally, never leave the vehicle plugged in after it is fully charged.

3. Monitor the Battery: Regularly monitor the battery to ensure everything is going fine.

2. Overheated Inverter

The inverter unit in your EV can get overheated from frequent use, impacting the machine’s performance. An inverter is a component in an electric vehicle that converts direct current (DC) into alternating current (AC). It is responsible for sending the power to the car’s motor and other electrical systems. 

If the inverter overheats, it can cause the car not to start or cause other electrical problems. Check the inverter unit and the cooling system to ensure they function correctly. You may want to consult a technician for this work.

3. Faulty Charging Port 

If your EV is not starting, the main fault is either due to the battery or the charging port. The Hyundai iONIQ 5 and 6 are equipped with a charging port that connects to an electrical outlet. 

This port charges the vehicle’s battery, allowing it to start and run. Unfortunately, the charging port can damage and prevent the vehicle from starting due to wear and tear or other issues. 

If the charging port is damaged, the vehicle won’t be able to draw power from the electrical outlet. This means the battery won’t be able to charge, preventing the vehicle from starting.

The best way to determine if the charging port is damaged is to inspect it visually. If the port is cracked or broken, it will need to be replaced. 

4. Loose or Damaged Cable Connections

Loose or damaged cable connections between the battery and the vehicle can prevent your EV from charging. And if there is no charge, your EV will not start. Check the cables for any damage or loose connections and have them repaired if necessary.

5. Technical Problems with the Vehicle Software

Technical problems with the vehicle software can also prevent your EV from starting. When this happens, it is usually because of a problem with the vehicle’s computer system or the software that controls it. Check the software and get it updated if necessary, or seek professional help if the issue persists.

6. An issue with the Key Fob’s Battery

Another common issue that can cause your vehicle to not start is a dead key fob battery. The key fob is an important component of the vehicle’s security system and is responsible for locking and unlocking the doors and starting the car. If the key fob is not working properly, the car will not start.

If the battery is indeed dead, it will need to be replaced. After the battery has been replaced, try starting your car again. You should be able to start your car without any further issues. If the issue persists, you should contact your nearest Hyundai service center.

In order to prevent this issue from occurring in the future, it is important to keep an eye on the battery in your key fob. Replace the battery in your key fob whenever necessary to ensure that it is in good working order.

7. Cold Weather

Your EV relies on battery power to get itself started. When the weather is cold, the battery may not have enough power to start the car. Cold temperatures slow down the chemical reactions that take place within the battery, reducing the amount of power it can generate. Make sure to properly store and maintain your EV during cold weather.

8. Insufficient Power Supply

Insufficient power supply to the vehicle can also prevent it from starting. When the electric car is not starting due to an insufficient power supply, it usually means that the car’s battery is not being charged properly. Check your power supply and make sure it is adequate enough for your charger.

9. Faulty alternator

The alternator is an important component of the car’s electrical system, as it is responsible for providing power to the vehicle’s electrical system. When the alternator is not functioning properly, it can cause the vehicle to have difficulty starting, as well as other electrical problems.

The most common symptom of a faulty alternator is a growling or clicking sound when you attempt to start the car. This sound is caused by the starter motor attempting to draw power from the alternator but not being able to do so. Other signs of a faulty alternator can include dim headlights, flickering or dimming interior lights, and the dashboard lights not illuminating.

If the alternator is indeed the cause of the issue, you’ll need to get it replaced with a new one. You can consult a technician or get help from the Hyundai service center. However, it is best to take your car to the nearest Hyundai service center.

10. Completed Battery Life Cycle

The battery life cycle can be completed over time, which can reduce the mileage and range of your EV even if it’s fully charged. This may even prevent your EV from starting. The Hyundai iONIQ 5 is rated for a range of 160,000 km, which should be pretty good. However, if you have a faulty battery, the story may be different.

Replacing the battery seems to be the only solution for this issue. The battery will need to be removed from the vehicle and replaced with a new one. This is a relatively straightforward process, but it will require some technical expertise. It’s also important to make sure that the new battery is compatible with the Hyundai iONIQ 5 / 6.
