Description: This bulletin describes the procedure to drain brake fluid and replace the brake master cylinder on certain 21MY Palisade (LX2) models. The brake fluid in the subject vehicles may be contaminated with mineral oil causing the brake master cylinder inner cup seals to expand. Expanded brake master cylinder inner cup seals could reduce hydraulic pressure applied by the master cylinder resulting in reduced braking function at the wheels. The driver may experience longer brake pedal travel, change in pedal feel, and extended stopping distance, increasing the risk of a crash.
Applicable Vehicles: 21MY Palisade (LX2) vehicles produced from March 9, 2021 through March 31, 2021.

Hyundai Service Learning – Recall 212 Service Procedure
1. Place the vehicle on a lift with an assistant seated in the driver’s seat.
Open the hood.
2. Discharge as much brake fluid as possible from the system according to the steps below.
NOTICE
Perform this operation in this order:
1) Rear Right
2) Front Left
3) Rear Left
4) Front Right
3. Starting at the rear right caliper, remove the bleed screw cover.
4. Connect one end of a bleed line to the bleeder screw, and the other end into a container to collect the brake fluid.
Open the bleed screw and have the assistant inside the vehicle pump the brake pedal to discharge the brake fluid.
Continue until the caliper is completely discharged of brake fluid.
Close the bleeder screw.
5. Move to the next caliper (front left) and repeat step #4 to discharge the brake fluid.
6. Repeat step #4 on the rear left caliper, then the front right.
7. Lower the vehicle and fill the brake fluid reservoir to the MAX line with DOT 4 brake fluid.
CAUTION
- Clean the area around the reservoir cap of any foreign substances before removing the cap.
- Be careful not to contaminate brake fluid with dust or other foreign substances.
- Do not allow brake fluid to come into contact with the vehicle body/paint. Immediately wipe any spills and flush with water if contact does occur.
8. Connect the air bleeding tool and adapter SST to the master cylinder.
Apply compressed air, and set the pressure to 3 bar (43.5 psi).
9. Connect a GDS to the vehicle and perform the HCU Air Bleeding Mode (under S/W Management → ABS/ESP).
10. Follow the directions for the HCU Air Bleeding Mode procedure on the GDS.
By the completion of the procedure, each caliper should have discharged fluid in these amounts:
Each front caliper: 100 mL
Each rear caliper: 150 mL
By the completion of the procedure, the master cylinder reservoir should be completely emptied of any brake fluid.
If any brake fluid remains, repeat the HCU Air Bleeding Mode procedure until completely empty.
11. Record the customer’s AM/FM/satellite radio station presets.
Turn the vehicle’s ignition to OFF.
Remove the battery by disconnecting the negative battery terminal, then the positive terminal, then the tie-down clamp.
Remove the air cleaner assembly according to the service manual procedures:
Engine Mechanical System → Intake and Exhaust System → Air Cleaner
12. Disconnect the brake fluid level sensor connector.
Remove and replace the brake master cylinder according to the service manual procedures:
Brake System → Brake System → Master Cylinder
NOTICE
The replacement master cylinder includes a new, preinstalled O-ring.
Before installing the new master cylinder, be sure to remove the original O-ring if it is left attached to the brake booster.
13. After installing the new master cylinder, fill the reservoir with DOT 4 brake fluid to the MAX line.
14. Bleed all four calipers starting with the rear right caliper. Connect a bleeding tube to the caliper bleed screw, leading to a collection container:
1. An assistant seated in the driver’s seat presses and releases the brake pedal several times, then holds the pedal depressed.
2. With the pedal depressed, open the bleeder screw to release air/fluid into the container.
3. Repeat #1 and #2 until no bubbles remain in the line.
4. Move to the next caliper and repeat the process until air is removed from all 4 lines.
NOTICE
Refer to the service manual for brake bleeding procedures:
Brake System → Brake Bleeding Procedures
15. Fill the brake fluid reservoir to the MAX line.
Connect the air bleeding tool and adapter SST to the master cylinder.
Apply compressed air and set the pressure to 3 bar (43.5 psi).
Connect a GDS to the vehicle and perform the HCU Air Bleeding Mode (under S/W Management → ABS/ESP).
Follow the directions for the HCU Air Bleeding Mode procedure on the GDS.
Repeat this process for all 4 calipers in the correct order.
Refill the brake fluid reservoir to the MAX line.
16. Using the GDS, perform a brake system pressure check:
From the starting screen, select Data Analysis.
17. Select ABS/ESC system.
18. Watch the three brake pressure parameters while gradually depressing the brake pedal:
1) Pressure Sensor – Pressure
2) Primary Pressure Sensor
3) Secondary Pressure Sensor
This operation should take about 20 seconds. Be sure to press the pedal very firmly to reach full braking pressure.
Confirm that the brake pressure values rise when gradually depressing the brake pedal.
The service procedure is complete after verification of brake pressure.
Reconnect the negative battery terminal and re-program the customer’s AM/FM/satellite radio station presets.
NOTICE
If proper brake pressure/operation is not achieved, perform the brake bleeding process again for both Normal Brake System and ESC Brake System.
Refer to the service manual for brake bleeding procedures:
Brake System → Brake Bleeding Procedures

Chronology :
September 2021
On September 2, 2021, HMC informed HMA’s NASO of an investigation being conducted in Korea involving eleven (11) Korean domestic vehicles produced from March 9, 2021 through March 31, 2021 for potential contamination of the brake fluid. NASO searched its field information databases and found three (3) unique U.S. vehicle incidents reporting a low or spongey brake pedal. NASO recovered and shipped two (2) brake master cylinder units from the identified incidents for further testing by the supplier in Korea.
On September 22, 2021, NASO shared its investigation status with NHTSA’s ODI during its recurring monthly review of safety-related topics.
October 2021
On October 14, 2021, HMC informed NASO of the parts analysis results confirming the presence of mineral oil in the brake fluid of the incident brake master cylinders and the ensuing effect on the brake master cylinder’s inner cup seal causing low braking ability due to reduced internal pressure. Based on this information, on October 19, NASO convened its North American Safety Decision Authority and decided to conduct a safety recall of vehicles produced in the subject date range for further evaluation into root cause of the brake fluid contamination. The investigation will actively continue to determine if a specific root cause and defect trend exists.
As of the date of this filing, Hyundai is not aware of any crashes, fires, or injuries related to the defect condition in the U.S.

This notice applies to your Hyundai, VIN: Dear This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. Hyundai has discovered a defect which relates to motor vehicle safety exists in your vehicle, with the VIN shown above. Hyundai is initiating a safety recall to repair a condition involving the service brake system in certain model year 2021 Hyundai Palisade vehicles in the U.S. and Canada. What is the problem? The brake fluid in the subject vehicles may be contaminated with mineral oil causing the brake master cylinder inner cup seals to expand. The cause of the contamination is under active investigation. Expanded brake master cylinder inner cup seals could reduce hydraulic pressure applied by the master cylinder resulting in reduced braking function at the wheels. The driver may experience longer brake pedal travel, change in pedal feel, and extended stopping distance, increasing the risk of a crash. What will Hyundai do? Your Hyundai dealer will have the brake fluid flushed and brake master cylinder replaced. This procedure will be performed at NO CHARGE to you. What should you do? Please contact your nearest Hyundai dealer to schedule the recall repair as soon as possible. If the Malfunction Indicator Light is illuminated in your vehicle, you should seek service at your Hyundai dealer as soon as possible.
