Service bulletins for the 2017 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.

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

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-20-10-0022020-03-09. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. On certain Model 3 vehicles, the LH side of the 12V battery bracket support might come loose due to improper welds during manufacture.
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-18-14-001 R12019-10-15. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. On some Model 3 vehicles, the top surface of the Instrument Panel (IP) carrier is prone to premature outlines or stains, such as an object left on the IP carrier in the sunlight. These outlines or stains can be temporarily removed, but can return, making it difficult to remove permanently. In addition, the surface of the IP carrier might be overly susceptible to scratches when attempting to clean it.
SB-18-17-002 R12019-03-11. Service bulletin. ELECTRICAL SYSTEM. Certain Model 3 vehicles might have increased resistance at ground terminals, and might not provide sufficient signal reference ground at specific connectors.
SB-18-44-010 R32019-03-11. Service bulletin. ELECTRICAL SYSTEM. On certain Model 3 vehicles, the charge port power terminals have pin deadfronts that might become dislodged from the terminals, causing the charge handle to not fully connect to the vehicle and therefore preventing the High Voltage (HV) battery from charging.
SB-19-44-0022019-03-11. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. On certain Model 3 vehicles, water might enter the inductive sensor in the charge port door assembly, causing the charge port door to be inoperative.
SB-18-44-0102019-02-25. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; ELECTRICAL SYSTEM. On certain Model 3 vehicles, the charge port power terminals have insulator pins that might become dislodged from the terminals, causing the charge handle not to fully connect to the vehicle and preventing the High Voltage (HV) battery to charge.
SB-18-44-010 R22019-02-19. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. On certain Model 3 vehicles, the charge port power terminals have pin deadfronts that might become dislodged from the terminals, causing the charge handle to not fully connect to the vehicle and therefore preventing the High Voltage (HV) battery from charging.
SB-18-44-010 R12019-02-19. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. On certain Model 3 vehicles, the charge port power terminals have insulator pins that might become dislodged from the terminals, causing the charge handle to not fully connect to the vehicle and therefore preventing the High Voltage (HV) battery from charging.
SB-18-20-0052018-12-10. Service bulletin. ELECTRICAL SYSTEM. On some Model 3 vehicles, the Occupant Classification System (OCS) frequency might be out of range because of electrical interference on the front passenger seat harness, causing the airbag indicator to display on the touchscreen.
SB18170122018-11-19. Service bulletin. ELECTRICAL SYSTEM. Some Model 3 vehicles might have been manufactured with the C-pillar electrical harness(es) routed incorrectly, causing a gap between the upper C-pillar trim and side rail trim.
SB18160092018-11-19. Service bulletin. ELECTRICAL SYSTEM. On some Model 3 vehicles, one or two HV battery breather valves might be missing or improperly installed.
SB-18-40-004 R12018-09-10. Service bulletin. ELECTRICAL SYSTEM. On certain Model 3 vehicles, an issue in the CAN transceiver internal to the drive unit might result in intermittent communication errors, causing the vehicle to go into limp mode or not start.
SB-18-14-0012018-07-16. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. On some Model 3 vehicles, the top surface of the Instrument Panel (IP) carrier is prone to premature outlines or stains, such as an object left on the IP carrier in the sunlight. These outlines or stains can be temporarily removed, but can return, making it difficult to remove permanently. In addition, wiping the surface of the IP carrier might result in scratches.
SB-18-16-004 R12018-07-16. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; ELECTRICAL SYSTEM. On certain Model 3 vehicles, the one-time use bolts that attach the high voltage controller to the penthouse cover were not torqued to Tesla?s internal specification.
