Service brakes

3 reports
“the Hyundai ioniq 5 doesn't turn on its brake lights when you're using single-pedal driving, as shown in this youtube video: https://youtu.be/U0YW7x9U5TQ?t=97 these should be recalled because you can bring the vehicle to a complete stop without the brakes turning on”

Vehicle speed control

1 report1 crash
“When approaching a turn, I let off the accelerator but the car didn’t stop accelerating. Instead, it gently kept accelerating. I applied the brakes and the car started slowing down but not at the same rate I was applying brake pressure. Therefore I floored the brakes to try coming to a complete stop. Sadly, the cars ABS system did not engage, half of the car hopped over the curb at about 20 mph. I was able to steer the car back onto the road where it finally came to a stop but acted like it wanted to keep going until full blackout power loss happened. The car was deemed a total loss by my insurance company American Family. Essentially, the vehicle malfunctioned causing the accelerator to stick which caused the car to be harder to control than designed. The car malfunctioned by not engaging the ABS system as well. There is a recall on this exact problem for the 2017-2019 model but not for my 2020 even though it was manufactured during that campaign. It all happened very quickly and I was very lucky this did not involve another vehicle.”
