What's wrong, in plain English

The sensors that are supposed to detect hydrogen gas leaks in the fuel system may fail to do their job. If a leak isn't detected, it can increase the risk of a fire, whether the car is parked or being driven.

What you should do

1. Check your VIN at nhtsa.gov/recalls. 2. Park outside and away from structures until repaired, and contact a Hyundai dealer (1-855-371-9460) for the fix. 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 22V258000.
