I am seeking an independent expert evaluation of a battery failure that occurred in my 2024 VinFast VF8. The malfunction affected the 12V auxiliary battery approximately four months after purchase. While the manufacturer provides a 3-year warranty on the 12V battery, the dealership has claimed—without diagnostic evidence—that the issue resulted from the vehicle being run down to 0% battery charge multiple times.

I’m requesting your assistance with

A diagnostic inspection of the 12V and related systems

A written expert opinion regarding the root cause of the failure

An assessment of whether this type of malfunction is consistent with reasonable use or indicative of design or manufacturing defects

This evaluation may support a warranty reimbursement effort, so clarity and technical accuracy are appreciated. I’m prepared to cover all applicable costs for diagnostics and documentation, and I can provide full service records, vehicle history, and correspondence upon request.

How much will you charge me to present the court with the technical testimony to strengthen my legal case
