Tesla is rolling out an emergency over-the-air update to Cybertrucks suffering from Power Conversion System failures, enabling the trucks to keep driving on DC fast charging until replacement hardware becomes available. The company is covering the cost of that Supercharging for affected owners — but has stopped short of issuing a formal recall.

What the PCS does and why it matters

The Power Conversion System is the Cybertruck's onboard AC-to-DC converter. When it fails, the truck loses the ability to charge at home from a Wall Connector or standard outlet; only DC Supercharging remains functional because that path bypasses the PCS entirely, according to Not A Tesla App. For an early-adopter Cybertruck owner who relies on overnight home charging, a failed PCS effectively strands the vehicle unless they can reach a Supercharger every few days.

The OTA workaround

Tesla's firmware update ships specialised code that allows the battery management system to accept DC fast charging even when the AC hardware is offline, according to reporting from Not A Tesla App and Drive Tesla Canada. The update is a stop-gap, not a fix — the PCS hardware still has to be replaced — but it keeps the truck usable while waiting for parts.

To offset the cost of relying on paid Supercharging for daily driving, Tesla is giving affected owners free Supercharging until the permanent repair is complete. Drive Tesla Canada reports that Tesla has told service centres a larger wave of replacement PCS units is due in the internal service system imminently, which should shorten the wait.

Still no recall

The notable gap in Tesla's response is the absence of a formal recall. PCS failures have been reported across owners forums and in service logs for months. A recall would force Tesla to notify every affected VIN through the national safety regulators in each market, document the defect, and set binding repair timelines. The free-Supercharging-plus-OTA approach keeps the affair off the official recall books, which matters both for PR and for the regulatory footprint.

What European Cybertruck owners should know

There are no official Cybertruck deliveries in the European Union — the truck has not received EU type approval and continues to be incompatible with several EU lighting, mirror and bumper rules. The few Cybertrucks circulating on European roads are grey imports registered under individual-vehicle approval schemes, most visibly in Germany, the Czech Republic and Slovakia. Those owners are on their own: Tesla's European service network does not stock Cybertruck-specific parts like the PCS, and shipping a replacement from a North American service centre typically takes weeks.

If you own a grey-import Cybertruck in Central Europe, the practical implications are:

  • AC home charging may stop working at any time on 2024-built trucks. Plan for Supercharger access.
  • Tesla's free-Supercharging programme is US-specific as far as can be confirmed. European owners should expect to pay at their local Supercharger.
  • The 7-year/70,000-mile ZEV powertrain warranty that explicitly covers the PCS applies only to 2026 and later model-year Cybertrucks, per Not A Tesla App. Earlier trucks are on the shorter basic warranty.

The bigger picture

The PCS issue is a reminder that Cybertruck remains a first-generation vehicle with first-generation problems. Tesla's response is faster than a legacy automaker's would be — firmware fixes push in days rather than quarters — but speed does not substitute for the durable engineering required for the PCS to simply not fail. Cybertruck hopefuls in Europe waiting for official sales have another reason to stay patient.
