The model(s) and model year(s) listed are a general approximation of the affected VIN list. Refer to the VIN/Bulletin Tracker or Customer/Vehicle profile to determine
applicability of this bulletin for a particular vehicle.

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

Condition
A firmware diagnosis feature is being introduced on Model 3 and Model Y vehicles that monitors wheel alignment over
time. This feature detects changes in wheel alignment that may be related to incorrect tire pressures, degraded ball
joints, bushings or damaged suspension links.
If the feature determines that an inspection at a Tesla Service Center is required, a customer-facing alert will appear
on the touchscreen.

Correction
Inspect the tire pressure, ball joints, bushings, suspension links and front and/or rear subframe; and replace the
component(s) if needed.

NOTE: If inspection determines that replacements are necessary, follow the instructions below:
•

If only suspension links (and not subframes) require replacement:
1.

Add correction code S042531004 to the Service Visit.

2.

Add the Service (Remove and Replace) correction code for the affected suspension part to a
separate activity.
NOTE: If needed, Pair or Set correction codes may exist. Refer to the Correction Code database
for more information.
NOTE: The parts required for this repair should be automatically populated to the repair order
according to the correction performed. If parts are not automatically added to the repair order, refer
to the Parts Catalog to add the required parts.

3.

If more than 1 suspension part requires replacement, and a pair/set correction code does not exist,
add correction code 31000000 “Additional Suspension Link (Access Already Performed) (Remove
and Replace)” to a separate activity in the Service Visit, one time for each additional suspension
link replaced.
NOTE: Refer to the Parts Catalog to add the required parts.

•

If the front and/or rear subframe require replacement, add S042531004 to the Service Visit, and then add
the corresponding subframe replacement Service correction code(s) to a separate activity in the Service
Visit. Refer to the Correction Code database for more information.
NOTE: If the front and/or rear subframe and suspension components require replacement, add only
the subframe correction code to a separate activity.
