Why the reported issue matters

Coolant contacting the EPCU circuit board may cause a loss of drive power, increasing the risk of a crash.

Official NHTSA campaign record

Prepare your observation

Keep existing warnings or observations for service. This guide does not ask you to probe wiring, disconnect a battery or open a high-voltage assembly.

A reported defect describes the campaign. It does not establish what caused a symptom on your individual vehicle, and absence of a symptom does not establish that an open recall is complete.

The reported manufacturer remedy

Dealers will inspect and replace the EPCU, as necessary, free of charge. Owner notification letters were mailed March 22, 2023. A second notice will be sent once the final remedy is available. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 239.

Timing language in the official record

Your campaign-specific service questions

Use these questions with the official report. Keep the answers beside the remedy record; “discussed” records a conversation, not a completed repair.

  1. Does the manufacturer confirm that campaign 22V941000 applies to this VIN, including the report’s equipment and production restrictions?

    A matching model and year is only a starting point. The official lookup or manufacturer must establish the individual vehicle’s status.

  2. The source describes a pending remedy or parts. What is available now for this VIN, and which interim instructions still apply?

    The dated official record describes development, future availability or a later remedy step. It does not establish today’s parts or appointment availability. Confirm the current remedy and any interim instructions with the manufacturer.

  3. Which electrical component or software function is covered, and what interim charging, parking or use instructions does the manufacturer give?

    Compare the answer with the reported component: ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY:THERMAL MANAGEMENT:FLUID/COOLANT.

  4. If an inspection determines which work is needed, what was inspected, what was found, and which corrective work followed?

    Ask for the inspection result as well as the final action. A parts list alone may not describe an inspection-based remedy.

  5. Which items in the reported replacement remedy for 22V941000 were replaced, and are they identified on the work order?

    Keep the replaced items and the campaign number together so that a later visit can distinguish recall work from other repairs.

  6. What dated document records the remedy performed under 22V941000, and what should I do if the reported concern remains?

    Keep campaign completion and unresolved symptoms as separate questions. A saved worksheet or booked appointment does not establish a repair.
