Service bulletins for the 2020 Tesla Model 3

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.

112 on file from NHTSA, as of 2026-10-19.

Bulletins, newest first
SB22330022023-04-24. Service bulletin. ELECTRONIC STABILITY CONTROL:AUTOMATIC (ASC); POWER TRAIN. Some Model 3 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-23-20-002 R22023-04-10. Service bulletin. AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION; 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-23-20-002 R12023-04-10. 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-23-20-0012023-04-10. 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-R62022-11-28. 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.
SB22330032022-06-13. Service bulletin. ELECTRONIC STABILITY CONTROL:AUTOMATIC (ASC); ELECTRICAL SYSTEM. Some Heat Pump Model 3 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.

SB21170072022-05-31. Service bulletin. ELECTRICAL SYSTEM. On certain Model S, Model X, and Fremont-built Model 3 vehicles, the Printed Circuit Board (PCB) for the RH side repeater camera may lose electrical continuity over time, resulting in premature failure of the camera.
SB21170062022-05-31. Service bulletin. BACK OVER PREVENTION; ELECTRICAL SYSTEM. On certain Model S, Model X, and Fremont-built Model 3 vehicles, the Printed Circuit Board (PCB) for the LH side repeater camera may lose electrical continuity over time, resulting in premature failure of the camera.
SB2118002R52022-05-02. 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.
SB22170042022-05-02. Service bulletin. ELECTRICAL SYSTEM. On certain Model S, Model X, and Fremont-built Model 3 vehicles, the Printed Circuit Board (PCB) for the LH and RH side repeater cameras may lose electrical continuity over time, resulting in premature failure of the cameras.
SB21170072022-02-28. Service bulletin. ELECTRICAL SYSTEM; BACK OVER PREVENTION. On certain Model S, Model X, and Fremont-built Model 3 vehicles, the Printed Circuit Board (PCB) for the RH side repeater camera may lose electrical continuity over time, resulting in premature failure of the camera.

SB-21-18-002 R32021-11-08. 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 R32021-11-08. 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.
