ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM
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.

SERVICE BRAKES, EXTERIOR LIGHTING
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.

ELECTRICAL SYSTEM
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.

FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
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.

Charging prematurely terminates before completed. Dealer denies knowledge of this. However suggested charging at "reduced" as opposed to "maximum" level. Even charging at "reduced" setting, charging still terminates before complete.

Occasionally, the vehicle sometimes doesn't start and allow me to engage to Drive gear from being turned off/Parked. I sometimes have to turn the car off and back on 1-2 times for the car to start like normal and allow me to select drive or reverse. Additionally, I have never been able to successfully sync my vehicle with my hyundai bluelink account despite efforts to troubleshoot with Bluelink representatives.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
When starting vehicle, presents a warning message in instrument panel of "Check electric vehicle system". The stated description indicates: "This warning message is displayed when there is a problem with the electric vehicle control system. Refrain from driving when the warning message is displayed." This could be an issue with the battery system, or steering system that puts others in danger due to the unpredictable nature of the error. The Hyundai app that reports vehicle statuses does not show any error or diagnostic codes.

ELECTRICAL SYSTEM
Vehicle is supposed to be able to charge at 48A on an AC charger but it does not do this during the months when ambient temperatures are above freezing. Poorly designed thermal management by the manufacturer causes charging to stop when the local temperature at the charge port door exceeds the threshold. The only way I can charge this car at home outside of the winter months is to lower the EVSE amperage to 32A which results in the car taking longer to fully charge than it’s supposed to. This car is supposed to be able to AC charge at 11.5 kW with 48A but it simply cannot do that most of the time. This issue is widely reported on the Ioniq 5 forums and is not isolated to me.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
Twice this week while charging my Ionic 5 the charging stops before it is completely charged to the set point. Once the set point was at 80% and once at 100%. Both times the charging stopped and I received the message below. None of the reasons listed in message was a cause of the stopping. I have called my dealer and they are checking w/service dept to see if I need a software update. I am waiting to hear back but there is obviously something wrong with the rate of charge. I am using a Jukebox home charger.

ELECTRICAL SYSTEM
When AC charging my car, It quickly overheats and disables charging. I've measured the temperatures at 239°F using OBD reader. The only way to continue charging is to reduce charge amperage. If it is reduced to 32 amps the temperature seems to stabilize before reaching the 240° emergency cut off.

ENGINE, POWER TRAIN
EV goes into power limited mode when on interstate when going ~50 miles while driving 70mph or more. Happened each of my 3 times on interstate of about that distance. First time was Sat 4/29 while in eco mode with 70% battery and 82°F outside, 1 hr drive 50+ miles. Second time was in normal mode Friday 5/12, 55% battery 72°F outside 1 hr drive 50+ miles. Third time was in normal mode and it happened after 42 miles. I scheduled a service after the first incident but they were only able to take it on 5/31. When this happens you lose ability to accelerate and have to coast to the side of road and let it sit for 10+ minutes to clear and then can resume, I would take surface roads after it occurred. Impacts safety for self and others, as it drastically slows without brake lights causing a high chance of being rear ended. The last incident was close to it. As it was getting worse I stopped driving on interstate with it. Car has been at the dealership's service department since 5/31. They were able to easily reproduce once they finally got to it. They diagnosed a bit and then consulted design engineers. Diagnosed on and off for a couple weeks and have finally decided to replace the drive motor. Part received Friday 6/16, to be installed tomorrow 6/20. We'll see if that addresses.
