Review the request
We review the vehicle, reported symptoms, warning lights, diagnostic codes, ZIP code, and service-location details.
Request an on-site review for a supported hybrid. We confirm the vehicle, ZIP code, $150 diagnostic fee, and availability before the appointment is accepted.
The exact checks depend on vehicle support, safe access, and the tools and data available for that vehicle.
We review the vehicle, reported symptoms, warning lights, diagnostic codes, ZIP code, and service-location details.
At the appointment, accessible codes and battery or hybrid-system data are reviewed when the supported vehicle and conditions allow it.
We explain what the available information indicates, what it does not prove, and which next step may be appropriate.
The review can help organize the symptoms, codes, and accessible system data so you can understand the available service options and questions that still need an answer.
A diagnostic trouble code or warning light is not, by itself, a final diagnosis of the battery pack or a guarantee that replacement will resolve every symptom.
The listed diagnostic fee is $150. It may be credited toward an eligible replacement only when that credit is stated in your written quote.
We explain the available findings and any follow-up questions or service options. The diagnostic does not require you to purchase a replacement.
When replacement is an available option, the battery choice, price, written warranty, location, and timing are confirmed before that service is accepted.
Submit the vehicle and ZIP code so we can review eligibility and availability.
