Service bulletins for the 2020 Tesla Model Y
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.

| SB19-20-003-R3 | 2023-12-18. Service bulletin. EXTERIOR LIGHTING; AIR BAGS; ELECTRICAL SYSTEM. On some Model 3 and Model Y vehicles, the Occupant Classification System (OCS) signal might be affected by electrical interference in the seat electrical harness, causing the airbag indicator to display on the touchscreen. |
|---|---|
| SB-21-18-002-R6 | 2022-11-28. Service bulletin. ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY THERMAL:MANAGEMENT:SOFTWARE. Certain Model 3 and Model Y vehicles may be equipped with refrigerant pressure/temperature (P/T) sensors in the heat pump that can fault over time. |
| SB2233005 | 2022-06-13. Service bulletin. ELECTRONIC STABILITY CONTROL:AUTOMATIC (ASC); SERVICE BRAKES, HYDRAULIC:POWER ASSIST:ELECTRIC:CONTROL MODULE; ELECTRICAL SYSTEM:WIRING. Some Model Y vehicles were built without a hydraulic control unit (HCU) wake-up wire, and in rare circumstances, braking and stability control related alerts may appear on the instrument cluster and touchscreen during the vehicle power-on process. Such faults can typically be corrected and the affected functionality restored with a vehicle power cycle. |
| SB-19-20-003 R2 | 2020-10-19. Service bulletin. ELECTRICAL SYSTEM; AIR BAGS. On some Model 3 and Model Y vehicles, the Occupant Classification System (OCS) signal might be affected by electrical interference in the seat harness, causing the airbag indicator to display on the touchscreen. |
| SB-20-40-003 | 2020-10-19. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN. The rear drive unit contains an inverter that did not go through internal reliability testing. |
| SB-20-44-002 | 2020-08-10. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. Some Model Y vehicles were manufactured with a charge port busbar safety cap and/or PE (Protective Earth) busbar that might not meet internal specifications, resulting in intermittent vehicle charging capability. |
| SB-20-16-004 | 2020-07-06. Service bulletin. ELECTRICAL SYSTEM. Certain Model 3 and Model Y vehicles may have a loosened fastener inside the HV battery assembly, which could cause the HV battery to power down. |
| SB-20-10-001 | 2020-07-06. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. Some Model 3 and Model Y vehicles might have a charge port door that is overflush (protrudes in comparison) to the LH taillight assembly. |
| SB-20-17-006 | 2020-07-06. Service bulletin. ELECTRICAL SYSTEM; LATCHES/LOCKS/LINKAGES:HOOD:LATCH. On certain Model Y vehicles, the hood latch actuator connector wires are installed in the incorrect position, causing the hood latch to open upon vehicle wake up; this will prompt a driver alert and prevent the vehicle from switching into drive mode until the hood latch is closed. |
