Tesla is finally officially addressing the Power Conversion System (PCS) failures impacting many Cybertrucks on the road today. This includes extending warranty coverage for the component to eight years or 150,000 miles, as well as preparing to reimburse owners who previously paid for repairs.
Tesla is now sharing details with impacted customers through Tesla Service, confirming that the longer coverage applies even after the Cybertruck’s four-year / 50,0000-mile Basic Vehicle Limited Warranty expires.
Extended PCS Coverage
On July 29th, a senior Tesla Service executive informed us that official communication regarding the PCS was on its way.
“FYI, official communication launching soon to Cybertruck owners on PCS. We’ll be extending warranty coverage for it and reimbursing owners that have already paid.”
They also added that Tesla was still finalizing the necessary backend changes but wanted to make clear that they were working toward a resolution for customers.
One day later, Tesla Service began providing owners with more specific details. Impacted customers are now receiving messages about the extended warranty coverage for PCS2 repairs and diagnostics.
The new coverage aligns the PCS2 with the Cybertruck’s high-voltage battery and drive-unit warranty: eight years or 150,000 miles, whichever comes first. Tesla’s existing Basic Vehicle Limited Warranty lasts four years or 50,000 miles.
That is a substantial improvement for early Cybertruck owners, particularly high-mileage drivers who were previously exposed to expensive out-of-warranty repairs.
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.

Next steps for existing owners:
– Model year 2026: PCS warranty is now standard at 7 years/70k miles
– Model year…
Tesla Acknowledges an Updated Part Revision
The service message also acknowledges that earlier Cybertrucks use a PCS2 design that could benefit from improved long-term reliability. Tesla is now on Revision G of the design, with many trucks on the road with earlier revisions, as late as Revision F, requiring replacement.
Tesla will also begin proactively replacing older PCS units. “We have identified an opportunity to improve the long-term reliability of the PCS2 on earlier Cybertruck models. Newer vehicles already feature an updated part revision designed for improved performance.”
The wording stops short of calling the issue a defect, and Tesla has not announced a recall. It also remains unclear whether all Cybertrucks equipped with the earlier revision will receive a proactive replacement or whether Tesla will prioritize vehicles showing diagnostic warnings or other signs of an impending failure.
However, the extended warranty means owners should no longer have to hope the component fails before the original 50,000-mile coverage expires.
Reimbursements are Coming
Tesla has confirmed another important part of the resolution process. Those owners who have already paid for PCS repairs out of pocket will be reimbursed.
Some high-mileage owners had received repair estimates running into the thousands of dollars after losing their Basic Vehicle Limited Warranty coverage. Tesla later reduced those invoices to just $1,000 through goodwill adjustments, but owners were still left paying for a failure tied to bad hardware.
Tesla has not confirmed how reimbursements will occur, but we recommend proactively reaching out to Tesla Service for those who have already paid.
What’s the Problem?
The Power Conversion System combines several essential power-electronics functions, including converting AC electricity from a Wall Connector or Level 2 charger into DC electricity for the high-voltage battery. It also supports Cybertruck's 48-volt electrical architecture.
When part of the system fails, affected owners commonly lose the ability to charge at home and power devices from the truck's power outlets. On the flip side, DC charging at Superchargers usually continues to work, as it delivers power directly to the battery, bypassing the PCS.
Still No Extended Cybertruck Warranty
While Tesla is extending the warranty on the PCS to match that of the high-voltage battery pack, it has not yet launched an extended warranty program for the Cybertruck, nearly three years after its launch. We’re hoping that Tesla will launch an extended warranty program similar to the one they have for the rest of the vehicle lineup now that this issue is finally being resolved.
Tesla has now also extended the drivetrain warranty for the Cybertruck to seven years.
