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.
104 on file from NHTSA, as of 2026-10-19.
By type
By component
| SB-23-20-002 R1 | 2023-04-10. Service bulletin. AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION. Certain Model 3 and Model Y vehicles may need a different Occupant Classification System (OCS) installed in the front passenger seat before servicing its subcomponents. |
|---|---|
| SB-23-20-002 | 2023-04-10. Service bulletin. SEATS. Certain Model 3 and Model Y vehicles may need a different Occupant Classification System (OCS) installed in the front passenger seat before servicing its subcomponents. |
| SB-23-20-001 | 2023-04-10. Service bulletin. SEATS; AIR BAGS. When certain Model 3 and Model Y vehicles receive a different Occupant Classification System (OCS) in their front passenger seats during vehicle servicing, they may require safety vent type front passenger airbags to maintain compatibility between the front passenger seat and the front passenger airbag. |
| 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. |
| SB2118002R5 | 2022-05-02. Service bulletin. FUEL SYSTEM, GASOLINE. 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. |
| SB-21-18-002 R3 | 2021-11-08. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM. 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. |
| SB-20-31-006 R3 | 2021-11-08. Service bulletin. STEERING; SUSPENSION. On certain Model 3, Model Y, and Model X vehicles, there may be a water ingress path to both front upper control arm ball joints that, over time, could possibly lead to surface corrosion of these ball joints. This may result in a creaking sound coming from the front suspension when steering at low speeds and under high loads. This is exclusively an NVH condition only and does not result in premature failure of the ball joints. |
| SB-20-31-006 R2 | 2021-11-08. Service bulletin. SUSPENSION. On certain Model 3, Model Y, and Model X vehicles, there may be a water ingress path to both front upper control arm ball joints that, over time, could possibly lead to surface corrosion of these ball joints. This may result in a creaking sound coming from the front suspension when steering at low speeds and under high loads. This is exclusively an NVH condition only and does not result in premature failure of the ball joints. |
| SB-21-12-003 | 2021-05-24. Service bulletin. VISIBILITY; EQUIPMENT ADAPTIVE/MOBILITY; STRUCTURE:BODY:DOOR; EQUIPMENT. Some Model Y vehicles equipped with auto-dimming door mirror glass have difficulty adjusting the LH door mirror to extreme vertical angles. |
| SB-21-18-001 R1 | 2021-04-26. Service bulletin. FUEL SYSTEM, GASOLINE. 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. |
| SB-21-18-002 R1 | 2021-04-26. Service bulletin. FUEL SYSTEM, GASOLINE. 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. |
| SB-21-18-002 | 2021-04-26. Service bulletin. FUEL SYSTEM, GASOLINE. 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. |
| SB-21-18-001 | 2021-03-15. Service bulletin. ENGINE AND ENGINE COOLING. Some 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. |
| SB-21-17-002 | 2021-03-15. Service bulletin. STRUCTURE. The grounding path conductivity for some Model Y front body controller modules might cause the vehicle touchscreen to display an erroneous ?Hood latch sensor requires service? message. This condition will not affect any functions of the frunk latch. |
| SB-21-12-001 | 2021-02-22. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. On certain Model Y vehicles, the front and/or mid aero shield panel(s) may not have been installed at the factory. In addition, if one or both panels are missing, a four wheel alignment may have not been performed. |
| SB-20-31-012 | 2020-12-14. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; STEERING; EQUIPMENT; SUSPENSION. On certain Model Y vehicles, the Front Upper Control Arm (FUCA) to steering knuckle fastener for both LH and RH sides of the front suspension might be loose, or the FUCA to steering knuckle nut(s) might be missing altogether. |
| 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-20-10-003 | 2020-08-10. Service bulletin. STRUCTURE. On some Model Y vehicles, front fascias with an injection date in a certain date range might have potential delamination/peeling issues. |
| SB-20-18-001 | 2020-08-10. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE. An NVH-reducing A/C compressor acoustic blanket was added to Model Y on May 26, 2020. Vehicles built before this date are eligible for a retrofit for owners who complain of elevated HVAC noise at the front of the vehicle. |
| 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. |
