Contaminated brake fluid can reduce Palisade braking
NHTSA campaign 21V840000 lists the 2021 Hyundai Palisade for a condition in which contaminated brake fluid can reduce Palisade braking.
What the reviewed source says
Start with the documented condition, not a parts guess.
NHTSA lists the 2021 Hyundai Palisade in safety campaign 21V840000. The official record says: The brake fluid may be contaminated, which can cause the brake master cylinder inner-cup seals to swell, and reduce braking performance. The stated safety consequence is: Reduced braking performance can extend the distance required to stop the vehicle, increasing the risk of a crash. A make, model and year match does not confirm that a specific VIN is included or that the repair remains open.

Check recalls by VIN
A VIN search checks the displayed NHTSA records for an unrepaired safety recall associated with one vehicle. A model search shows only the wider campaign population.
Read guide ↗When a car is unsafe
A warning light does not always mean the same thing, but weak brakes or smoke leave little room for experimentation. Damaged tires and certain recall instructions can do the same.
Read guide ↗Why symptoms overlap
“It makes a weird noise” is useful human language. Diagnosis begins when that language is tied to the exact vehicle and its operating conditions.
