Official summary
On certain Model S and Model X vehicles, the 2nd generation High Voltage (HV) harness between the Front Junction Box (FJB) and the front drive unit might become disconnected, which could prompt a driver alert to bring the vehicle to a safe stop, advise the driver of limited acceleration, or prevent the driver from operating the vehicle upon startup. This condition does not affect steering or braking.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
