Tesla is addressing a hardware issue affecting early Cybertrucks. The company recognized that the PCS in pre-2026 models fails frequently, leaving owners without home charging capabilities. Now Tesla is taking steps to help affected drivers by extending warranty coverage and rolling out a software fix.
Hardware changes and warranty extensions
The PCS manages the flow of electricity from home chargers to the vehicle battery. But some owners started losing this capability shortly after taking delivery, relying instead on public stations. Then Tesla engineers designed a new version of the hardware for newer production runs. The company stated: “We’ve 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.”
Tesla is changing its warranty terms to cover the older parts for a longer period. So for the 2024 and 2025 model years, the PCS warranty lasts for eight years or 150,000 miles. New 2026 models include a standard PCS warranty for seven years or 70,000 miles, extending the life of the truck’s protection.
Many early adopters paid their own money to replace the faulty hardware when it broke. Yet Tesla plans to issue refunds for these expenses soon. The company outlined the plan by saying, “Starting in the next few weeks, we will reimburse any charges for those who already required a PCS replacement and paid out of pocket.” Service centers will process the refunds for owners who present their previous invoices.
Still, some drivers are waiting for replacement parts. Supply chain constraints delayed the distribution of the updated hardware. The company added, “We’re working hard on increasing supply chain availability of this improved version.”
Over-the-air software fix
A broken PCS stops a truck from charging at home, but it does not affect public DC fast charging. So Tesla sent a software update to the fleet, letting owners continue using the Supercharger network. The patch bypasses the faulty home charging hardware entirely.
And Tesla is paying the bill for public charging sessions until the trucks get repaired. The company stated: “As an immediate remedy, we’ve rolled out a software update so you can keep Supercharging even if a PCS failure occurs, and have enabled free Supercharging for trucks waiting for part availability.” Drivers will see the sessions flagged as free in their account history.
