What the official report says

Tesla, Inc. (Tesla) is recalling certain 2017-2021 Model S, Model 3, Model X, and 2020-2021 Model Y vehicles operating software version 2021.36.5.2. A communication error may cause false forward-collision warning (FCW) or unexpected activation of the automatic emergency brake (AEB) system.

Official NHTSA campaign record

Why the reported issue matters

Unexpected activation of the AEB system may cause the car to stop suddenly, increasing the risk of a crash.

Official NHTSA campaign record

Prepare your observation

Keep the affected display or visibility function and the circumstances of an observed problem in the record. Do not recreate a visibility failure 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

Tesla Service has released an over-the-air (OTA) software update, free of charge. The recall began October 25, 2021. Owners may contact Tesla customer service at 1-877-798-3752. Tesla's number for this recall is SB-21-00-004.

Official NHTSA campaign 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 21V846000 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 image, lamp or visibility function is covered by this campaign, and what should I do while the remedy is outstanding?

    Compare the answer with the reported components: FORWARD COLLISION AVOIDANCE: WARNINGS; FORWARD COLLISION AVOIDANCE: SENSING SYSTEM: CAMERA; FORWARD COLLISION AVOIDANCE:SOFTWARE; FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING.

  4. Which module and software completion record demonstrate that the update for 21V846000 was applied?

    The source identifies an over-the-air update option. Ask how completion is confirmed for this vehicle; a downloaded update or notification is not itself a service record.

  5. What dated document records the remedy performed under 21V846000, 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.
