What's wrong, in plain English

The software that runs your Tucson's central control unit may not be compatible with the vehicle. This can cause the headlights or taillights to stop working. When lights go out, it becomes harder for you and other drivers to see, which raises the risk of a crash. Dealers have already updated the software on all affected vehicles at no cost, so most owners will not receive a separate notification letter about this recall.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your vehicle is included. 2. Contact a Hyundai dealer or Hyundai customer service at 1-855-371-9460 to confirm the software update was completed. 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 21V938000.
