Service bulletin SB-20-50-001

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.

NHTSA's summary

Certain Model 3, Model S, and Model X vehicles were equipped with 2nd generation Universal Mobile Connector (UMC) inline units having a proximity circuit resistor that is out of specification. This resistor within the affected UMC inline unit might prevent charging, might interrupt charging while in progress, and might affect the functionality of the UMC charge handle button when disconnecting the charge handle from the vehicle charge port.
