What's wrong, in plain English

Hyundai is recalling certain Accent vehicles because the brake master cylinder may have been manufactured with sharp edges. These sharp edges can damage the inner oil seal that is inside the master cylinder. If the seal becomes damaged, it can result in reduced braking performance, meaning the brake pedal may need to travel farther, or the vehicle may need a longer distance to stop.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your vehicle is affected.
2. Contact a Hyundai dealer, or call Hyundai customer service at 1-855-371-9460, to schedule the repair.
3. Dealers will replace the brake master cylinder free of charge.

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 21V937000.
