Bulletin Classification: This campaign bulletin addresses a known non-safety-related condition and provides
recommended technical diagnosis and repair procedures. Apply this procedure to all vehicles in the affected VIN range
listed. These instructions assume knowledge of motor vehicle and high voltage electrical component repairs, and should
only be executed by trained professionals. Tesla assumes no liability for injury or property damage due to a failure to
properly follow these instructions or repairs attempted by unqualified individuals.

Condition
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.

Correction
Replace the HV battery positive and negative contactors with updated parts.
