← Full guide: EV Charger Warranty Claim: Evidence and Escalation

Document the resolution so a repeat fault is easier to claim

Document the resolution so a repeat fault is easier to claim. Check the cause, evidence to keep, recovery steps, and escalation.

Start here

When the charger is repaired or replaced, record the new serial number, firmware version, service date and test result. Ask the technician to confirm that the vehicle charged successfully at the expected power and that protective devices were tested where applicable.

What applies to this exact problem

When the charger is repaired or replaced, record the new serial number, firmware version, service date and test result. Ask the technician to confirm that the vehicle charged successfully at the expected power and that protective devices were tested where applicable.

If the warranty period continues, note whether the replacement part has its own warranty or only the remaining original term. This can matter if the same failure returns months later.

Keep site and product warranties separate

The electrician’s workmanship warranty and the charger manufacturer’s product warranty may have different durations and exclusions. Store both. When a problem returns, you can immediately direct the complaint to the party responsible for that layer.

A well-managed warranty case ends with more than a working charger. It ends with a diagnosis, documented repair, verified safe operation and a clear record of who is responsible if the same fault comes back.

Check these first

  • Record the symptom before repair or reset changes the evidence.
  • Ask for the diagnostic result and the exact warranty or policy clause used for the decision.
  • Compare the measured fault and service history with the written coverage, not a verbal “wear and tear” label.

Fix it in this order

  1. Record the symptom before repair or reset changes the evidence.
  2. Ask for the diagnostic result and the exact warranty or policy clause used for the decision.
  3. Capture vehicle model, VIN, battery/charger serial where available, odometer, warning codes, and the exact symptom.
  4. Ask the authorised service centre for diagnostic findings and the warranty clause used for approval or denial.
  5. Separate normal range variation from a measurable fault using repeatable conditions, charging logs, error codes, or state-of-health evidence.
  6. Keep invoices, job cards, firmware/service history, and photographs of warnings or damage.
  7. For subsidy/incentive issues, verify model eligibility, invoice treatment, registration details, and portal status independently.

Build the proof pack

  • Purchase invoice and warranty
  • Job cards/diagnostic report
  • Charging/range/error evidence
  • Subsidy or portal application record where relevant

Avoid making the case harder

  • Opening or repairing high-voltage components yourself
  • Accepting a warranty denial without the clause/reason
  • Assuming brochure range is guaranteed in every condition

How you know it is really fixed

  • The defect or claim has a written technical decision tied to the applicable terms.
  • Repair, replacement, payment, or denial is complete and documented.

If it is still not fixed

  1. Manufacturer/dealer grievance
  2. Scheme/portal helpdesk when incentive-related
  3. Consumer remedy for unresolved product/service disputes
