Service bulletin SB-20-31-012

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Other bulletins for the same vehicles and component
SB-25-31-0042025-07-04. Service bulletin. 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.
