The main reasons for the slow ramp-up of replacement PCS (Power Conversion System)
parts for the Cybertruck boil down to a combination of unexpectedly high failure volume, manufacturing complexity, and supply chain realities for this component.
Why the Delay?
Tesla is addressing it aggressively: covering under warranty (with goodwill pricing for out-of-warranty), providing free Supercharging as a workaround, pushing firmware mitigations for partial functionality, and ramping newer revisions.
For 2026+ models, they've extended specific PCS warranty coverage. No full recall yet, as it's not deemed a safety issue (DC fast charging often still works).

Why the Delay?
- Sudden Surge in Failures Overwhelmed
Stock: Early Cybertrucks (especially pre-~July 2024 builds, often cited around the first ~ 75k units) used a PCS design with MOSFETs prone to thermal fatigue/failure, particularly under sustained high-amperage (e.g., 48A) home charging. Failures accelerated in early-mid 2026, creating a "tsunami" of repair requests.
Service centers quickly burned through existing spares, leading to national backorders. cybertruckown... +2 - Complex, Not Fully In-House Part: The PCS is a sophisticated bidirectional 48V power converter handling high-voltage to low-voltage conversion, charging, and more. It's not as vertically integrated as some Tesla components, so sourcing, qualifying, and scaling production of revised boards (e.g., newer Rev G or T2-G) involves suppliers, testing for reliability, and certification. This isn't as quick as ramping simpler parts. youtube
- Production and Logistics Realities: Tesla updated the design in production (new MOSFETs from ~ July 30, 2024), but retrofitting/replacing in the field for thousands of trucks takes time to manufacture at scale.
Service centers report parts arriving in batches, with ETAs slipping (weeks to 6-8+ weeks in many cases). Labor for replacement is also non-trivial (especially with armor packages), adding to bottlenecks. cybertruckown... +1
