What the official report says

Nissan North America, Inc. (Nissan) is recalling certain 2020 Nissan Murano, INFINITI QX60, 2021 Nissan GT-R, INFINITI QX50, and Q50 vehicles. The front steering knuckle or rear axle housing may have insufficient strength due to improper heat-treatment.

Official NHTSA campaign record

Why the reported issue matters

The steering knuckle or rear axle could deform upon impact, such as from hitting a curb, resulting in a loss of steering control, or possible wheel separation. Both of these conditions can increase the risk of a crash.

Official NHTSA campaign record

Prepare your observation

Record an existing steering concern without a test drive intended to provoke it. A lookup result does not diagnose steering behavior.

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 front steering knuckle and rear axle housing, as necessary, free of charge. Owner notification letters were mailed July 26, 2021. Nissan owners may contact customer service at 1-800-867-7669. INFINITI owners may contact customer service at 1-800-662-6200.

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 21V402000 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 steering component or assistance function is covered, and what transport instructions apply if a steering problem is present?

    Compare the answer with the reported components: SUSPENSION:REAR:AXLE:SPINDLE; STEERING:LINKAGES:KNUCKLE:SPINDLE:ARM.

  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 21V402000 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 21V402000, 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.
