Consumer Description
Vehicle experienced PCS (Power Conversion System/DC-DC converter) failure, rendering it completely undrivable—no 12V power, cannot charge or start. PCS is physically integrated inside high-voltage battery pack per service manuals. High-voltage battery warranty active (8yr/120k miles). Tesla service denies coverage citing "associated component" in vague emails—provided only general warranty table, no specific exclusion language despite repeated requests for exact quote/formal written denial. Escalated to managers: Offered "view-only" internal service bulletin on screen at meeting—no print/copy/photo allowed. Explicitly refused formal written denial letter.
