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.

The Ioniq 5 has a braking system that does not engage the brake lights on deceleration when in certain regenerative braking settings. This is dangerous as the car will quickly decelerate and not warn drivers behind you potentially causing a crash because they are unaware the Ioniq is stopping quickly. Please have Hyundai address the issue for recall.

12v battery died within 6 days and needed to be jumped. Another 4 days and the 12v will not hold a charge at all. This is a new 2023 Ioniq 5 Limited AWD. Odo on the lot was 13 miles. Odo at 10 days was around 280. Waiting to hear from Hyundai, but dealer confirmed 12v is bad. Currently unknown if ICCU is also faulty.
Service brakes mileage not reported 8 mo in service
The regenerative braking will not turn on brake lights unless the accelerator is fully unpressed. In the more aggressive modes (L3 and I-Pedal), the stopping power is very strong. Without brake lights, it catches other motorists off guard and they nearly hit me. For reference, I-Pedal mode is able to bring the car to a full stop on its own. This is dangerous. The brake lights need to come on depending on the rate of deceleration, not the accelerator pedal state. This can happen at any speed, but becomes more dangerous at highway speeds.
