On April 20, 2026, reports surfaced indicating that the Power Conversion System (PCS) in the Tesla Cybertruck was experiencing widespread malfunctions. As a result, numerous owners found themselves unable to charge their vehicles via AC at home. In more serious scenarios, the affected vehicles could not start at all. The bulk of these failures were reported in Cybertrucks that had been driven between 16,000 and 29,000 kilometers. Even after replacing the entire PCS assembly, some vehicles continued to encounter recurring problems. The PCS is a crucial part of the Cybertruck's power electronics, tasked with regulating all AC power entering the battery and supplying power to the vehicle's low-voltage electrical system. When a malfunction occurs, the vehicle may experience disrupted charging and display error messages on the dashboard. Upon inspection, these issues are identified as damage to the PCS system, necessitating a complete replacement. The repair costs are astronomical; previously, for vehicles no longer under warranty, the parts and labor costs for PCS system replacement ranged from $5,000 to $7,200. Although Tesla has recently lowered this cost to around $1,000, owners are still left to foot the bill themselves. Furthermore, service centers are grappling with severe parts shortages, causing multiple delays in vehicle pickup times for affected owners. Tesla has yet to file a formal recall request for this component with the U.S. National Highway Traffic Safety Administration (NHTSA) or take the initiative to notify owners about the issue.
