Document the actual symptom and the response to each repair. An EV's software and service-app history can be part of that record.
Identify the warranty that covers the concern
An electric vehicle may have separate coverage for the basic vehicle, battery, drive unit, and other components. Check the warranty issued for your vehicle, its delivery date, and applicable mileage limits. A battery warranty is not a promise that every change in range is a covered defect.
For an electric vehicle, we review the warranty, the unresolved problem, and the repair history just as carefully as the technology involved. Tell the firm about aftermarket equipment, damage, and changes to the vehicle so the full record can be assessed.
For a charging or range concern
Do not attempt an unsafe test or handle high-voltage components. Follow the manufacturer's safety guidance and contact an appropriate service professional when the vehicle may be unsafe.
- Note the date, battery state, temperature, and displayed warning.
- Record whether the concern occurred at home, at a public charger, or at more than one location.
- Keep service findings about the vehicle, cable, charging equipment, and software.
- Preserve towing and transportation records when the vehicle could not be used.
Software updates belong in the timeline
Save update dates, version information you can see, and service messages about what an update was intended to address. Note whether the symptom changed or returned afterward. Keep remote diagnostics and mobile-service records alongside service-center invoices.
If service records are stored in an app, download or preserve copies before changing accounts or transferring the vehicle. Avoid relying on a short notification that may disappear from the app.
What a recall does—and does not—tell you
Use NHTSA's official lookup to check for safety recalls and follow any safety instructions. A recall and an individual warranty claim ask different questions; the presence or absence of a recall does not by itself decide a lemon law case.
For any electric or plug-in hybrid vehicle, identify the exact model year and gather the warranty documents issued for that vehicle.
