Service bulletins for the 2019 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.

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

SB19-20-003-R32023-12-18. 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.
SB21170052022-05-31. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. Some Model 3 driver and front passenger seat electrical harnesses might get damaged from repeated fore and aft adjustments to the seat, which will trigger a restraint system alert.
SB21170052022-02-28. Service bulletin. ELECTRICAL SYSTEM. Some Model 3 driver and front passenger seat electrical harnesses might get damaged from repeated fore and aft adjustments to the seat, which will trigger a restraint system alert.
SB-20-17-010 R12020-12-14. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. On certain Model 3 vehicles, an open electrical circuit or short to ground near connectors X950 or X952 may display a restart alert on the touchscreen, or prevent the vehicle from starting altogether.
SB-20-17-0102020-11-16. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. On certain Model 3 vehicles, an open electrical circuit or short to ground near connectors X950 or X952 may display a restart alert on the touchscreen, or prevent the vehicle from starting altogether.
SB-19-20-003 R22020-10-19. 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-20-16-0032020-08-10. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. Certain Model 3 high voltage batteries may not have a sufficient quantity of bolts for the contactor DC link busbars, which may prevent the vehicle from charging or powering properly.
SB-20-10-0012020-07-06. 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-19-20-003 R12020-05-11. 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-20-50-0012020-03-09. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. 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.
SB-20-17-0012020-02-10. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY. When some Autopilot HW2 and HW2.5 Model S, Model X, and Model 3 vehicles are near airport ASR-9 radar antennae, the vehicle cameras might be affected by electromagnetic interference, and Autopilot/camera alerts might be displayed.
SB-19-20-0032020-01-06. Service bulletin. SEATS; AIR BAGS; ELECTRICAL SYSTEM. On some Model 3 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-19-16-0102019-08-12. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. The HV battery on some Model 3 vehicles might produce a subtle "thunk" noise when ascending or descending a mountain, or during Supercharging in colder climates. The "thunk" noise occurs when the air pressure outside the battery is different than the air pressure inside battery. The "thunk" noise does not indicate a fault or affect the performance of the HV battery.
SB-19-16-0082019-03-11. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Debris on the fixture used to mate HV battery clamshells might have damaged a cell during assembly, which could reduce range or limit charging.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
