Tesla Model S Plaid cutting out for two seconds — the intermittent gremlin no scan could find

What the diagnosis found

With no codes to chase, the platform mined the high-frequency vehicle log and aligned every dropout with a micro-interruption on the rear drive unit's high-voltage supply — a hairline crack in a busbar termination that only opened under chassis flex over one particular bump. Invisible at rest, on a lift, or to any scan tool.

Ranked probable causes

How the system reasoned

A sub-second drive cut-out that leaves no code and cannot be reproduced on a lift demands data, not guesswork. Mining the high-frequency log and aligning every dropout with chassis flex isolated a hairline busbar crack that opened only under load over a specific bump — a fault that two scan-tool visits had no way of seeing.
