Chronology :
– Beginning on or about August 17, 2021, the Factory Quality team detected a twisted right-hand curtain side airbag on a U.S. Model 3, using the automated vision system on the manufacturing line. The Production Quality and Process Engineering team confirmed that a non-conformance was generated to inspect and, if necessary, repair the twisted condition. The non-conformance was reported as closed prior to factory gating.
– The Production Quality and Process Engineering team commenced an engineering study to confirm production records of the Model 3. Tesla Service inspected the vehicle and discovered a twisted right-hand curtain side airbag. The team determined that the non-conformance on the vehicle was closed without a full repair and repair confirmation.
– From late August to October 2021, the team 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.
– On October 18, 2021, a recall determination was made.
