What's wrong, in plain English

Hyundai is recalling certain Kona Electric and Nexo vehicles because the brake system may pick up an abnormal signal from a sensor. When that happens, it can significantly cut down how much braking power the vehicle has. That means it could take longer to stop than expected, which matters most in situations where you need to brake quickly. The problem is related to the software that runs this electronic braking system.

What you should do

1) Check your VIN at nhtsa.gov/recalls to confirm your vehicle is included. 2) Contact a Hyundai dealer to schedule the software update; Hyundai customer service: 1-855-371-9460. 3) The repair is free.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 20V748000.
