A car owner has a persistent, undiagnosed engine issue (misfire, stalling, warning lights) that multiple mechanics cannot definitively fix, and suspects misdiagnosis from dealership.

Existing mechanic shops lack the tools or expertise to definitively diagnose intermittent engine issues, leading to costly trial-and-error repairs and uncertainty.
