Why This Matters
This recall addresses a significant safety concern. Unexpected activation of the Automatic Emergency Braking (AEB) system can cause your vehicle to stop suddenly without warning. Such an abrupt stop increases the risk of a rear-end collision with following traffic.
False forward-collision warnings (FCW) can also be startling and distracting to the driver, potentially leading to unsafe driving maneuvers.
What's Being Recalled
Tesla, Inc. is recalling certain 2021 Model S, Model 3, Model X, and Model Y vehicles. The issue specifically affects vehicles operating with software version 2021.36.5.2. A communication error within the FORWARD COLLISION AVOIDANCE: SENSING SYSTEM: CAMERA component can lead to incorrect readings.
This error manifests as either a "false forward-collision warning" or an "unexpected activation of the automatic emergency brake" system. The 2021 TESLA Model Y recall, identified by NHTSA ID 21V846000, aims to correct this software anomaly.
