The RED Review host experienced the exact PCS problem on his own Cybertruck about a year ago.

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.

If a Cybertruck's PCS fails out of warranty, the repair is not cheap.

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.

The RED Review host encourages Cybertruck owners who haven't attempted to back-feed their home to find somebody with a Power Share unit and try it.
