What's wrong, in plain English
Hyundai is recalling certain Ioniq 5 N vehicles that have the left-foot braking and N e-shift features. Software in the electronic brake system and vehicle control unit may cause the brakes to work less effectively whenever left-foot braking is turned on. On top of that, if the N e-shift feature is active, the car may keep accelerating on its own even after the driver takes their foot off the gas pedal, instead of slowing down as expected.
What you should do
2. Contact a Hyundai dealer, or call Hyundai customer service at 1-855-371-9460.
3. The software update is free, done over-the-air or by a dealer.
4. Until it's fixed, don't use the left-foot braking or N e-shift features.
Where do I find my VIN, and what do I tell the dealer?
