Repair Bulletin: This repair bulletin provides instructions on addressing a noted condition or possible customer concern regarding
the operation of Tesla vehicles. These instructions should only be performed by trained professionals.

This Service Bulletin supersedes SB-19-12-001, dated 19-Jan-19. Each content change is marked by a vertical line in

Condition
On some Model 3 vehicles, the front and/or mid aero shield panels might be susceptible to damage when driving
through standing water. This can result in damaged or missing panels. Updated panels are available which have a
more robust design than the original panels.

Correction
Upon customer complaint, or if the vehicle is already on a lift, inspect the panels to confirm the condition described. If
a panel is determined to be water damaged, or if a panel is missing, replace both panels with updated parts.

Procedure
1. Verify that the vehicle VIN is on the affected vehicle list and is subject to this bulletin.
•

If the vehicle VIN is not on the affected vehicle list, the vehicle does not qualify for this bulletin. Discontinue
the procedure.

•

If the vehicle VIN is on the affected vehicle list, continue to the next step.

2. Raise the vehicle (if not already on a lift) and inspect the front and mid aero shield panels for the type of damage,
if any.
•

If either the front or mid aero shield panel is missing, replace both panels.

•

Object-contact damage is evident from panel abrasion (Figure 1), sheared fasteners (Figure 2), or wear
through (Figure 3).
NOTE: Object-contact damage is not covered under warranty and is customer pay.
