Tesla Is Now Monitoring Cybertrucks for Charging Failures and Offering Free Supercharging

Tesla is taking a proactive step to address a known hardware issue affecting the charging systems of early Cybertrucks. A new screenshot from the Tesla mobile app indicates the company is running remote diagnostics to detect failing Power Conversion Systems (PCS) and is providing complimentary Supercharging to impacted owners while backordered parts needed to repair AC charging components are sourced.

Remote Diagnosis

A recent message sent to an affected Cybertruck owner through the Tesla app shows that the company is actively monitoring the fleet's charging hardware. The automated message explains that remote checks found an issue with the vehicle's charging system and that an in-person service visit is needed. Because the required part is currently unavailable, Tesla is contacting the owner in advance. The message states:

Remote diagnostics have been completed on your Cybertruck and indicate that your vehicle's charging system requires service. A required part is not immediately available, but we will reach out to schedule your appointment as soon as it is in stock.

Navigating the PCS Bottleneck

This outreach specifically concerns the Cybertruck's Power Conversion System. A large number of early Cybertrucks have experienced PCS failures, and the number of affected vehicles has been increasing.

The PCS is the key component that converts alternating current (AC) from wall outlets or Level 2 home chargers into the direct current (DC) needed to charge the high-voltage battery pack. When the PCS fails, the vehicle can no longer charge at home or at destination chargers.

Because the failure is limited to the AC-to-DC conversion process, the battery can still safely accept a direct DC charge. In most cases, with a failed PCS, a Cybertruck can continue to charge at full speed at any Tesla Supercharger or third-party DC fast-charging station.

Some owners have seen PCS issues affect other parts of the high-voltage system, preventing Supercharger use as well. Tesla has been prioritizing PCS replacements for owners whose trucks are completely unable to charge.

The Silver Lining

Losing home charging is a significant inconvenience for any EV owner, especially when replacement parts are delayed. To ease the impact, Tesla is leveraging the Supercharger network to help affected drivers. The service message adds:

In the meantime, your vehicle can safely charge using the Tesla Supercharging network or third-party fast charging stations. To help during this time, we are providing complimentary Supercharging until your repair is complete.

By offering free Supercharging, Tesla ensures affected Cybertruck owners are not stranded or forced to pay premium DC fast-charging rates. When replacement PCS units arrive at local service centers, Tesla will automatically invite the flagged owners to schedule their repair.
