What the official report says

Honda (American Honda Motor Co.) is recalling certain 2021 Acura RDX and 2022 CR-V Hybrid vehicles. A component in the right or left front driveshaft may have been improperly heat-treated, which could result in driveshaft failure.

Official NHTSA campaign record

Why the reported issue matters

Driveshaft failure can cause a sudden loss of drive power, or cause the vehicle to roll away when parked if the parking brake is not applied. Either condition can increase the risk of a crash or injury.

Official NHTSA campaign record

Prepare your observation

Record an existing symptom and its date. Do not reproduce a loss of power, stall or transmission fault in traffic.

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 replace the right or left front driveshaft as necessary, free of charge. Owner notification letters were mailed January 24, 2022. Owners may contact Honda customer service 1-888-234-2138. Honda's numbers for this recall are BBY, NBW, and OBX.

Official NHTSA campaign record

Confirm current remedy arrangements

The source does not explicitly establish current remedy availability. Ask the manufacturer about the applicable remedy, required parts or software, appointment arrangements and any interim instructions.

This describes the dated source record. Current arrangements for your VIN remain unconfirmed.

Additional official notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.

This campaign is open

Confirm current interim instructions, remedy availability and service arrangements. Keep the dated answer.

Not listed as open

Review earlier repair records and lookup limits if needed. A zero-open result does not explain an unresolved symptom.

Work order records recall work

Keep the campaign number, remedy and date together. Ask separately about a symptom that remains after the visit.

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 21V939000 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. What remedy, required parts or software, and appointment arrangements are currently available for this VIN, and which interim instructions apply?

    The source does not explicitly establish current remedy availability. Ask the manufacturer about the applicable remedy, required parts or software, appointment arrangements and any interim instructions.

  3. Which engine or transmission component is covered, and does an existing drivability problem need separate diagnosis?

    Compare the answer with the reported component: POWER TRAIN:DRIVELINE:DRIVESHAFT.

  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 21V939000 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 21V939000, 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.
