Tesla has announced a significant expansion of support for Cybertruck owners affected by Power Conversion System (PCS) failures, acknowledging that the original hardware used in early production trucks did not meet the company’s reliability expectations.
In a statement released on Friday, Tesla said it had “identified PCS electronics in pre-2026 Cybertrucks that do not meet our reliability standards and have made design changes to address this in newer vehicles.”
The company also confirmed a major warranty update. While 2026 Cybertrucks continue to include PCS coverage under their 7-year/70,000-mile powertrain warranty, all 2024 and 2025 Cybertrucks will now receive PCS coverage for 8 years or 150,000 miles.
Tesla also says owners who previously paid out of pocket for a PCS replacement will be reimbursed beginning in the next few weeks.
What Happened?
The announcement follows Tesla’s initial response to the issue earlier this year, when owners began reporting a growing number of PCS failures that disabled AC charging. The failures prevented affected Cybertrucks from charging at home or other Level 2 stations, forcing many owners to rely exclusively on DC fast charging while waiting for replacement parts.
At the time, Tesla stopped short of announcing a recall, despite calls from owners for one to be issued. Instead, it rolled out a software update that allowed Cybertrucks with a failed PCS to continue Supercharging and offered free Supercharging for owners waiting for repairs. While those measures helped reduce the immediate impact of the problem, they did little to address concerns about long-term repair costs or future failures.
Tesla’s latest announcement goes much further. By confirming that the revised PCS design is already being installed in newer Cybertrucks, the company has acknowledged that the original hardware was, in essence, defective. It also says it is working to increase supply of the updated component, which has been in short supply and resulted in weeks-long repair delays for some owners.
The expanded warranty is particularly significant for early Cybertruck buyers. Prior to this change, 2024 and 2025 models were covered only under Tesla’s standard 4-year/50,000-mile basic vehicle warranty for PCS-related repairs. Owners who experienced a failure outside that period faced repair bills that could reach several thousand dollars.
Although Tesla has still not issued a formal recall, they have now publicly addressed the issue for the first time. In doing so, they have extended warranty coverage to 8 years and 150,000 miles, will reimburse previous repairs, and continue to provide free Supercharging while replacement parts remain scarce.
