I bought FIXD for engine diagnostics and it completely missed a major problem, what should I do?

If FIXD failed to detect a serious engine problem, document everything immediately, including screenshots of the app results, repair invoices, mechanic reports, and the actual fault that was later discovered.

This helps prove the scanner provided incomplete or misleading diagnostics, especially if the issue caused additional repair costs.

FIXD is limited to standard OBD-II code reading and may not detect manufacturer-specific, intermittent, mechanical, fuel-pressure, or transmission-related failures.

A professional diagnostic scan with OEM-level equipment is the best way to confirm the real issue and prevent unnecessary part replacements.

You should also contact FIXD support and request a review or refund if the product did not perform as advertised for your vehicle.

If support remains unresponsive, posting on Xolvie can help apply public pressure.
