Service bulletins for the 2018 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.

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

Bulletins, newest first
SB-19-16-004 R12020-01-06. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. The clamshell graft inside the HV battery was not fastened to Tesla?s internal specifications. This condition might result in a reduction of vehicle driving range.
SB-18-16-013 R12019-10-07. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Certain Model 3 vehicles might have too few HV battery positive contactor mounting nuts installed, which can allow movement that might affect the conductivity of the contactor terminals.
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-19-16-0092019-03-11. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. On some Model 3 vehicles with the Long Range HV battery, a few cell interconnects within the HV battery are missing. This condition might result in a reduction of vehicle driving range.
SB-19-16-0062019-03-11. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Certain Model 3 vehicles might have a displaced fastener within the penthouse cavity, which might prevent the vehicle from starting, or charging the HV battery or 12V battery.
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-19-16-0012019-02-19. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. On certain Model 3 vehicles, the inner assembly of the high voltage (HV) battery positive and negative contactors might be in a weakened state and fail unexpectedly. Upon failure of either contactor, the high voltage system shuts down, and the vehicle cannot be charged or driven.
SB-19-16-0042019-02-19. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. The clamshell graft inside the HV battery was not fastened to Tesla?s internal specifications. This condition might result in a reduction of vehicle driving range.
SB-19-16-0032019-02-19. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; ELECTRICAL SYSTEM:WIRING. On certain Model 3 vehicles with Dual Motor, some wire bonds that connect the cells within the HV battery are not bonded to Tesla?s internal specifications. This condition might result in a reduction of vehicle driving range.
SB-19-16-0022019-02-19. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Certain Model 3 vehicles with the Long Range HV battery might have fasteners within the HV battery platter that are not torqued to Tesla?s internal specifications, which might affect HV battery reliability.
SB-18-16-0082018-10-15. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. On certain Model 3 vehicles, the rear drive unit HV header bolts and the positive contactor bolt within the High Voltage (HV) battery penthouse were insufficiently torqued to internal specifications during manufacturing.
SB-18-16-0072018-10-15. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; EQUIPMENT. On certain Model 3 vehicles, some bolts within the high voltage (HV) battery penthouse were insufficiently torqued to internal specifications during manufacturing.
SB-18-16-0062018-10-15. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. On certain Model 3 vehicles, the positive busbar nut under the power conversion system and additional bolts within the High Voltage (HV) battery penthouse were insufficiently torqued during manufacturing.
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.
SB-18-16-0052018-07-16. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Some Model 3 vehicles might have been manufactured without one or both HV battery breathers.
