A growing number of Tesla Cybertruck owners are reporting a critical failure that renders their vehicles unable to charge using AC home chargers. The issue stems from the Power Conversion System (PCS), a vital component responsible for managing AC charging and stepping down the high-voltage battery pack to power the truck's 48-volt electronics system.
Quiet Replacements Over Formal Recalls
While Tesla has not issued a formal safety recall for the component, reports indicate the company is aware of the defect. Tesla is currently replacing the faulty units on a case-by-case basis under warranty. However, the lack of a proactive campaign has left many owners in a difficult position, as the vehicle remains functional only if charged via the DC Supercharger network.
Supply Chain and Wait Times
The situation is further complicated by a shortage of replacement parts. Owners affected by the PCS failure have reported waiting several weeks for new units to arrive at service centers. Without a functioning PCS, the Cybertruck cannot convert standard household electricity into usable energy for the battery, effectively killing the convenience of overnight home charging for those impacted.
