Corrosion warrantyyr
Corrosion warranty covers perforation or rust-through for a stated period. It matters because EV ownership risk is split between general vehicle parts, the battery, software support and local service access. The headline term is only the start.
How to compare it
Check the exact wording. Surface rust, perforation and anti-corrosion inspection requirements are different things.
- Read years and kilometres together.
- Separate vehicle and battery coverage.
- Check local service access before trusting the headline.
What changes it
Warranty value changes with your annual distance, service rules, exclusions, battery health threshold, parts supply and local workshop coverage.
- Time and distance limits usually apply whichever comes first.
- Battery warranty often has a separate health threshold.
- Service history can decide whether a claim is accepted.
Common trap
Long corrosion warranty can require documented inspections to remain valid.
- Whichever comes first usually wins: time or kilometres.
- Warranty does not cover every kind of wear or damage.
Corrosion warranty: coverage over time
Coverage is a timeline with limits. Time, kilometres and state of health all matter.
