There is no rear windshield wiper and the design of the car causes much dirt/gunk to build up HEAVILY obscuring visibility There are times where I'm driving at night (esp. when it's raining) where I can barely make out the cars/objects behind me. It is very dangerous

While driving in the one pedal driving mode (“iPedal”), it is possible to rapidly slow the vehicle while keeping the accelerator pedal slightly depressed, which is the expected result for this regenerative braking mode. While rapidly decelerating in this mode, however, the brake lights do not illuminate while the accelerator pedal is slightly depressed. Even though regenerative braking is active and the car is rapidly decelerating, there is no brake light illumination. The brake lights only turn on if the accelerator pedal is not pressed at al…

I've owned this car for 4 months now. We own 2 electric cars, 1 ioniq 5 and 1 Fiat 500e. We have a level 2 charger in the garage. A month ago I noticed the ioniq stopped charging overnight. When I tried the next day, it charged for about 30 minutes, then I would get a msg on my phone saying charging had stopped. I can remotely start the charging again, but then it would stop every 10 or 15 minutes. This is still happening. The Fiat has no issues charging, leaving me to believe it's not the charger that is the problem. I've even reduced the char…

When using i-Pedal (one-pedal driving) mode in this vehicle, it can decelerate at a very fast rate but does not illuminate the brake lights unless the driver’s foot is completely off the pedal. For example, I can be driving 60mph and decelerate to ~2mph as quickly as other drivers coming to a complete stop, but my brake lights will not illuminate until my foot is **completely** removed from the pedal. This is contradictory to the way one-pedal driving works, since coming to a smooth and slow stop requires that you slowly lift off the accelera…

The contact owns a 2023 Hyundai Ioniq 5. The contact stated that the vehicle failed to charge at 120 or 240 volts. The charging unsuccessful alert was displayed. The contact stated that the vehicle only charged on a DC fast charger. The vehicle was taken to the dealer where it was diagnosed that the ICCU (Integrated Charging Control Unit) that allowed both high-voltage and secondary batteries in vehicles to be charged had failed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 50…

The Ioniq 5 offers a multi-level regenerative braking system, which slows the car down to varying degrees when letting off the accelerator pedal. While these systems work well to increase efficiency, the behaviour of the brake lights while in use is concerning. Very often the car is slowing considerably, enough to be akin to light braking, but the brake lights do not activate. This can be full let off the accelerator pedal and slowing with not brakes, or with a partial lift (especially on higher regen levels), where the vehicle is obviously slo…

12V battery does not seem to be charging. After 2 days of not being driven, 12v battery status is too low to start the car. Jump starting works but same think occurs after couple of days of not driven.
