Yes, PHEVs (Plug-in Hybrid Electric Vehicles) have specific long-term warranty protections that can reduce maintenance costs, particularly for high-voltage battery systems and powertrain components:
Federal and State Warranty Requirements
Federal law mandates at least 8 years/100,000 miles of coverage for hybrid/EV batteries. For PHEVs specifically, the EPA requires 8 years/80,000 miles for high-voltage batteries. California imposes stricter regulations:
- 2026 models onward: Batteries must retain 70% capacity for 10 years/150,000 miles
- 2030 models onward: 80% capacity retention required for the same period
Extended State-Specific Protections
Eleven CARB-aligned states (including California) require 15-year/150,000-mile warranties for ZEV powertrain components in PHEVs, covering:
- Battery packs
- Electric motors
- Power electronics
This applies only to plug-in hybrids, not conventional hybrids.
Manufacturer Examples
- Hyundai: Offers lifetime coverage for its Kona Electric battery (EV-only, not PHEV)
- Mitsubishi PHEV: Provides a 5-year/60,000-mile basic warranty, with 7-year/100,000-mile corrosion coverage
These extended warranties lower long-term costs by covering expensive battery replacements or major component failures. Always confirm state-specific protections and read manufacturer fine print regarding capacity retention clauses.
