Elevated severity

This campaign addresses a defect NHTSA classifies as carrying elevated crash or injury risk.

What the defect is

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.

Why it matters

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

The 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.

The manufacturer reports this remedy can be delivered as an over-the-air software update — a workshop visit may not be required.

What this page does not include

NHTSA's public recall feed does not supply an affected-population count, the manufacturer's own campaign number, owner-notification dates or a defect chronology for this campaign. Rather than estimate them, we omit them. Confirm whether a specific vehicle is affected — and whether the repair has already been done — using its VIN.
