Tesla admits Cybertruck PCS defect, extends warranty to 8 years

Tesla has officially acknowledged that the power conversion system (PCS) in pre-2026 Cybertrucks is defective, and it’s extending the warranty on those trucks to 8 years or 150,000 miles.

The reversal comes after months of owners paying up to $7,200 to replace a part Tesla now admits “does not meet our reliability standards.” The automaker sneakily tried to let the clear manufacturing defect pass warranties.
