Tesla is taking steps to address Cybertruck owners dealing with a growing number of Power Conversion System (PCS) failures, but the company is stopping short of issuing a formal recall, despite mounting reports of the issue across the fleet.
According to an update shared by Kyle Field on X, Tesla has begun rolling out a software update aimed at restoring limited functionality for affected vehicles. The interim measure came after he was notified repairs to his truck won’t happen until May due to a parts shortage.
Perhaps more notably, Tesla is offering free Supercharging to impacted Cybertruck owners while they wait for repairs. “Tesla will be covering Supercharging for all affected owners until they resolve the parts delay,” Field added.
I got an official update from Tesla about the Cybertruck PCS issue resolution:

* Tesla has pushed out a firmware update to all affected CT's that will enable Supercharging while AC is down (from the PCS failure).
* The FW is set to bypass Wi-Fi delay so any CT owner can download… https://t.co/Hlk8EzUS6X
The move is meant to address a major aspect of PCS failures. When the system fails, Cybertrucks lose the ability to charge via Level 2 (AC) charging, effectively eliminating home charging—one of the primary cost-saving advantages of owning an EV. In many cases, DC fast charging remains functional, but it comes at a significantly higher cost, making Tesla’s decision to temporarily cover Supercharging fees a meaningful, if partial, solution.
The PCS is a critical component in the Cybertruck’s electrical architecture, combining the onboard charger and DC-DC converter while also stepping down high-voltage battery power to support the vehicle’s 48-volt system. Failures typically present as “AC Charging Unavailable” errors, reduced charging speeds, or complete inability to charge on AC power. Some owners have also reported issues with Powershare functionality and specific fault codes tied to the PCS.
Reports of failures have surfaced across a wide range of Cybertrucks, from early Foundation Series builds to newer VINs, suggesting the issue is not isolated to a specific production batch. In some cases, failures have occurred at relatively low mileage, and there are instances of repeat failures even after the component has been replaced.
While Tesla has acknowledged the issue and is addressing it through service repairs, it has opted not to issue a recall. Instead, replacements are being handled individually as failures occur—a strategy that has drawn criticism from some owners, especially as parts shortages lead to extended wait times.
Cost is another concern. For Cybertrucks outside of warranty, PCS replacement can run as much as US$7,000. Tesla has reportedly reduced that cost to around US$1,000 as a goodwill gesture, though that still represents a significant out-of-pocket expense for affected owners for something that is clearly a chronic issue with the PCS.
Another one bites the dust. Cybertruck PCS failure.

Coolest part, 10 days for earliest appointment and it won't charge at a supercharger either.

Onwers of newer 2026 Cybertrucks don’t have to worry about this cost, as these vehicles now include a longer 7-year/70,000-mile powertrain warranty that explicitly covers the PCS.
