What's wrong, in plain English

Hyundai is recalling certain Ioniq Electric vehicles because an unstable electrical ground can cause the car to enter a fail-safe mode with less power and slower acceleration. In certain conditions while the vehicle is in this fail-safe mode, it may speed up on its own even after the driver has let go of the gas pedal.

1. Check your VIN at nhtsa.gov/recalls to see if your vehicle is affected.
2. Contact a Hyundai dealer to schedule the free repair; you can also call Hyundai customer service at 1-855-371-9460.
3. Dealers will update software and repair wiring at no cost to you.
