On [XXX], I received a warning on my 2023 IONIQ 5 that said “stop vehicle and check braking system” and the car went into “turtle mode”. I took it into the dealer for repairs and they said the issue was related to the 12V battery and returned the car to me as repaired. Then, on [XXX], I was driving the car and I got the same error message but this time the car’s brakes didn’t work.

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.

When using most of the regenerative braking levels, including the one-pedal driving mode named “I-Pedal,” the brake lights will not illuminate until the drivers foot is fully off the gas pedal, or manually applying the brakes. This can create a dangerous, life threatening scenario leaving surrounding drivers unaware the vehicle is slowing.

Brake lights do NOT come on when decelerating in I-PEDAL mode and Level 3 regen brake modes, perhaps more. The car should instead generously apply brake lights by default anytime deceleration occurs via regen braking.
