NHTSA Campaign Number: 21V-846

Unexpected Activation Of The Automatic Emergency Brakes

A software communication error may cause false forward-collision warning (FCW) or unexpected activation of the automatic emergency brake (AEB) system.

On October 23, 2021, Tesla received reports of false FCW and AEB events from customers after they released software update 2021.36.5.2 to vehicles in the limited early access Full-Self Driving (Beta) population.

Tesla remedied the condition with firmware release 2021.36.5.3, which was released to the subject population Over The Air (OTA) on October 25, 2021. The OTA remedy will carry forward in firmware release 2021.36.5.3 and later. As of this filing, more than 99.8% of the subject population (i.e., all vehicles but for 17) installed firmware release 2021.36.5.3 or a later release. No further action is necessary from owners whose vehicles are equipped with firmware release 2021.36.5.3 or a later release.

The Vehicles Affected Include:
2017-2021 Model 3
2017-2021 Model S
2017-2021 Model X
2020-2021 Model Y

Front Suspension Lateral Link Could Separate

A smaller number of 2019-2021 Model 3 and 2020-2021 Model Y Tesla vehicles are being recalled for front suspension link fasteners that may loosen and allow the lateral link to separate from the sub-frame. Tesla became aware of this problem in June 2021 after receiving 39 service reports from vehicles with one or both front suspension lateral link fasteners found loose or missing.

Tesla will inspect affected vehicles for proper torque of the fasteners of both front suspension lateral links. If loose or missing fasteners are found, Tesla will re-torque the fastener to the correct specification. If vehicle damage from a loose or missing fastener is found during the inspection, Tesla will replace damaged components.

Side Curtain Air Bag May Be Twisted

This recall includes two Tesla Model 3 vehicles, one built on September 20, 2020 and one built on December 20, 2020.

In August 2021, Tesla Factory Quality team detected a twisted right-hand curtain side airbag on a Model 3. Using the automated vision system on the manufacturing line, the team confirmed that a non-conformance was generated. They conducted an investigation into all Model 3 production records, including images captured by vision inspection, repair records, and repair confirmation notes. This investigation identified two additional VINs in the U.S., the records from which Tesla could not conclusively determine the left- and right-curtain side airbags were not twisted.

Tesla will be contacting these owners with instructions to return to their dealership to have the left and right side curtain airbags inspected for proper alignment and orientation. If a twist or other condition is identified with either curtain side airbag, Tesla will realign the airbag to the correct specification.
