What's wrong, in plain English

Some Palisade SUVs may have brake fluid that has become contaminated. This can cause seals inside the brake master cylinder to swell, and swollen seals reduce how well the brakes perform. When braking performance is reduced, it can take a longer distance to bring the vehicle to a stop. Needing more distance to stop increases the chance of a crash happening before the vehicle can stop in time.

What you should do

1. Check your VIN at nhtsa.gov/recalls. 2. Contact a Hyundai dealer at 1-855-371-9460 to schedule the repair. 3. The brake master cylinder replacement and brake fluid flush are 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 21V840000.
