- Tesla officially acknowledged that the power conversion system (PCS) in pre-2026 Cybertrucks is defective, admitting the part "does not meet" certain standards (source text truncated).
- Tesla extended the warranty on affected pre-2026 Cybertrucks to 8 years or 150,000 miles as a direct response to the defect admission.
- Cybertruck owners had been paying up to $7,200 out of pocket to replace the defective PCS part in the months before Tesla's reversal.
- The warranty extension covers trucks manufactured before 2026, indicating the defect affects a specific production window of the Cybertruck lineup.
Why it matters: Pre-2026 Cybertruck owners who already shelled out up to $7,200 for a now-acknowledged defective part now have warranty backing—potentially opening reimbursement claims and forcing Tesla to absorb repair costs it previously pushed onto buyers. The 8-year/150,000-mile window signals Tesla is bracing for sustained failure risk in early Cybertruck PCS units.
