2023 HYUNDAI IONIQ 5 Complaints

The vehicle keeps tripping out due to the charger load on the car. This is concerning due to the repeated failures charging.

Level 2 charging at home interrupting. I charge with a level 2 24a in my dryer outlet and my ionic 5 sel 2023 rwd interrupt its charging 2 times. I had to force my shelf to continue.

This is an electric vehicle, stated in product literature and safety sticker at charge port that it is capable of 48A / 240V AC charging. Under normal circumstances, the charging port overheats when supplied with 48A / 240V AC. The vehicle aborts charging due to the overheating charge port when ambient temperature is above 70 degrees Fahrenheit. This is a safety risk, and the charge port needs to be designed in a way that it will not overheat when charging at levels specified in the manual and safety tags located at the charge port, regardless of normal ambient temperatures.

Vehicle is rated to charge at up to 48 amps. Charging at over 32 amps causes a failure due to overheating

I have an Emporia charger connected to a 60AMP breaker that can charge at a constant 48amps. This was installed as per the codes by a certified electrician. I have been owning this car since October 2022 and has over 14k miles on the car. Till last week, the car charged at 48amps without any issue. But since yesterday, charging starts smoothly till 1-2 hours. Then every 6-7 minutes, charging stops for some seconds and starts back up. After several cycles of stop and start charging, the entire charging ends before reaching the set limit. 2 weeks ago, the dealership updated the VCU as per the latest June TSB Hyundai released.

Loss of power when accelerating, Warning lights came on and off in blinking style. After losing power to zero , it would jump accelerate hard then die again.

When using the one pedal driving or "iPedal" mode, the brake lights do not illuminate when braking unless your foot is completely off of the accelerator pedal. This is very dangerous because the vehicle can be stopped very hard without completely removing your foot from the gas pedal. I have stopped using this mode after almost being rear-ended three times within a week due to the car behind me not realizing that I am braking. This issue is gaining media attention. After doing research online, I have learned that there are lots of other people that have noticed the same behavior and have stopped using this mode as a result.

Vehicle fails to charge at full level 2 charging speeds. When set to 48 amps the vehicle quickly reaches a high AC inlet temperature and stops the charging. When lowered to 38 amps the vehicle charges for longer but eventually reaches the high AC inlet temperature and once again stops charging. Level 2 charging must be set to a low max of around 32 amps to successfully charge the car without it stopping the charging. Car is advertised to support 48 amps but does not work correctly. MyHyundai app constantly gives the "Electric vehicle charging alarm" message which indicates the issue occuring.

When charging the car on an AC Level 2 charger, the vehicle overheats and charging fails. This is dangerous and can cause overheating/fire to electrical equipment as well as rendering the vehicle inoperable due to insufficient charge. There are no warnings ahead of time prior to failure. The problem is widespread and replicable, as evidenced by reports of forums, reddit, YouTube, and even a TSB issued by Hyundai that fails to adequately resolve the issue.

The vehicle’s 12v system failed under normal use. The vehicle is unable to be started without a jumpstart. I think this is related to the issues other Ioniq 5s are seeing.
