Tesla Deploys OTA Update and Free Supercharging for Cybertruck PCS Failures

Following widespread reports of Cybertruck owners experiencing Power Conversion System (PCS) failures, Tesla has launched an urgent over-the-air update and interim policy response. While a permanent hardware fix is still limited by parts availability, the company is rolling out an emergency update to keep affected trucks on the road.

Kyle Field, whose truck is currently impacted by the PCS issue, shared details.

Update over cellular

When a Cybertruck suffers a PCS failure, the vehicle loses the ability to process alternating current (AC), eliminating the option to charge at home via a Wall Connector or a standard outlet. To mitigate this, Tesla is pushing a targeted firmware update to all affected vehicles.

The update includes specialized code so the truck’s battery management system will allow DC fast charging at Superchargers even when the AC charging hardware is completely offline.

Given the urgency, Tesla has configured this firmware to bypass the normal Wi‑Fi requirement. It is being delivered over the vehicle’s cellular connection so owners can install it as soon as possible. Because Tesla software is deployed in staggered waves, it may take a few days for the update to reach every affected vehicle.

Free Supercharging to bridge the gap

Since a failed PCS forces owners to rely entirely on the Supercharger network instead of lower-cost residential electricity, Tesla is covering the cost.

Tesla will cover all Supercharging fees for owners with a verified PCS failure. This relief will remain in place until the vehicle can be serviced and the hardware replaced.

Aggressive parts restocking

While the software update and free Supercharging provide a temporary lifeline, the main constraint has been a severe shortage of replacement PCS units. Service centers have been backlogged, leaving many trucks waiting weeks for repairs.

Tesla is working in parallel to resolve these supply constraints. A large influx of replacement parts is expected to go live in the internal service system in the coming days, which should help clear the backlog and restore home‑charging capabilities to these early Cybertrucks.
