Inspect LH Front Lower Lateral Link

Condition

On certain Model Y vehicles, the fasteners that secure the left-hand (LH) front lower lateral link to the subframe may not have been torqued to internal specification. A fastener not torqued to specification may loosen over time or separate from the subframe, which could cause the lateral link to separate from the subframe.

 

Correction

Inspect and confirm that all bolts that secure the LH front lower lateral link to the subframe are torqued to internal specification. If symptoms relating to the condition are present, re-torque the bolt(s) and/or install new bolt(s) to internal specification.

 

Procedure

1. Remove the LH front wheel and release the LH side of the front aero shield to gain access to the LH front lower lateral link (refer to Service Manual procedure 31013402).

2. Perform a torque check on the bolts (x2) that attach the LH front lower lateral link to the subframe (torque 115 Nm) (Figure 1).

NOTE: If bolt(s) are not installed, install new bolt(s).

3. Install all parts that were removed for access.

Chronology of the Defect/Noncompliance Determination:

  • Beginning late November 1, 2022, through early November 2, 2022, the production tool used to secure the left-hand (LH) front suspension lateral link to the subframe on affected vehicles manufactured at the Austin, TX, factory was offline due to a faulty sensor. (All affected vehicles completed production on November 2, 2022.) As a result, the procedure to secure the LH lateral link was performed manually by a technician who also validated the torques.
  • On November 17, 2022, as part of a routine inspection prior to customer delivery, Tesla Service identified two fasteners that secure the LH lateral link to the subframe were not torqued to specification on one vehicle manufactured at the Austin, TX, factory during the time period the procedure was performed manually by a technician. Both fasteners were torqued to specification prior to customer delivery.
  • On November 18, 2022, based on the finding in the November 17, 2022, inspection, Tesla Engineering began a risk assessment of the condition and began reviewing manufacturing records to assess the suspected root cause and identify the scope of a potentially affected vehicle population. As a precaution, vehicles not yet delivered to customers manufactured during the time period the procedure was performed manually by a technician were placed in containment for specific inspection of the LH lateral link fasteners prior to customer delivery. Between November 18 – 28, 2022, vehicles in pre-delivery containment were inspected to confirm that LH lateral link fasteners were torqued to specification.
  • On November 22, 2022, as part of the inspections of vehicles in pre-delivery containment, two LH lateral link fasteners on one vehicle were identified as not torqued to specification. Both fasteners were torqued to specification prior to customer delivery.
  • Late on November 23, 2022, Tesla Engineering completed its review of manufacturing records, confirming the suspected root cause, risk assessment, and affected population.
  • On November 28, 2022, immediately upon returning from the Thanksgiving holiday, the condition and assessment were reviewed with leadership and a recall determination was made.
  • On November 29, 2022, Tesla Service began proactively outreaching to affected customers to schedule service appointments to remedy the condition.
  • As of December 5, 2022, customers of seven of the nine affected vehicles have scheduled appointments for service in December 2022 to remedy the condition.
  • Also as of December 5, 2022, Tesla has not identified any warranty claims or field reports (received between November 2, 2022, and December 5, 2022) received for U.S. vehicles related to or potentially related to this condition. Tesla is not aware of any crashes, injuries, or deaths related to this condition.
  • On December 9, 2022, Tesla Service learned of an occurrence of a customer Model Y with very low mileage built on November 2, 2022, at the Austin, TX, factory with a LH front suspension lateral link whose fasteners were not torqued to specification. Tesla Engineering began a review of manufacturing records to assess the root cause and identify the scope of a potentially affected vehicle population.
  • On December 13, 2022, the assessment identified a suspected root cause to be no secondary check that the fasteners were torqued to specification because the technician’s manual entry of the torque value in the station controller may have inadvertently edited torque values automatically entered by the production tool to secure the right-hand (RH) front suspension lateral links and/or inadvertently bypassed torque non-conformances from being generated for the LH or RH lateral link for secondary checks that certain fasteners were torqued to specification. On December 14, 2022, the assessment identified 17 additional vehicles with potentially the same condition.
  • On December 15, 2022, having completed a review of manufacturing records and confirming the suspected root cause, risk assessment and affected population, a recall determination was made to amend and expand recall 22V-895 to include the 17 additional vehicles identified.
  • As of December 19, 2022, Tesla has identified one warranty claim and zero field reports (received between November 2, 2022, and December 19, 2022) for U.S. vehicles related to or potentially related to this condition. Tesla is not aware of any crashes, injuries, or deaths related to this condition.
