If a Cybertruck's PCS fails out of warranty, the repair is not cheap.
AI Fact-Check
“While specific out-of-warranty Cybertruck PCS repair invoices are not widely available as most vehicles are still under the 4-year/50,000-mile warranty, owner discussions on forums report costs ranging from $3,000 to over $7,000. One Cybertruck owner with 60,000 miles reported paying $7,200 for a PCS replacement. Another forum member broke down the cost as ~$1,800 for the part plus labor, totaling over $3,000. For other Tesla models like the Model 3, a similar PCS replacement is estimated by Tesla to cost around $2,500, confirming that this is a multi-thousand-dollar repair. Context: The Power Conversion System (PCS) is a critical component that converts AC to DC power for charging the high-voltage battery. A failure can prevent the vehicle from charging via AC power sources. Most Cybertrucks are still under warranty, so these out-of-pocket costs are not yet widespread but are a concern for owners approaching the warranty expiration.”

The PCS board is designed to convert AC power to DC power and vice versa, allowing the Cybertruck to charge its DC battery from AC sources.
The RED Review host experienced the exact PCS problem on his own Cybertruck about a year ago.
If one of the AC parts of the PCS board is lost, the Cybertruck's AC charging amperage drops from 48 amps down to 24 amps, effectively halving the charging rate at home.
The only way to notice a PCS problem without an explicit dashboard notification is to go into service mode and look for active alerts, specifically a message alluding to PCS failure.
The PCS board is buried very deep in the Cybertruck, requiring parts of the truck bed to be removed and access behind or underneath the air compressor for replacement.
