A car owner is unable to identify the source of a vibration/noise after an engine replacement, despite multiple checks, and the dealer provided no effective solution.

Workarounds Described

• manually checking all exhaust bolts and heat shields with hand
• brake torque test to check engine movement
• feeling around exhaust with hand for leaks (no smoke machine)

Implied Software Gaps

• A diagnostic app that uses phone sensors to analyze vibration frequency and guide step-by-step troubleshooting.

VibraSense Pro

A mobile app that uses phone sensors and an optional low-cost vibration sensor to diagnose vehicle vibrations and noises. It guides users through a step-by-step diagnostic workflow, recording frequencies and comparing to a crowdsourced database of vehicle-specific issues. It provides likely causes and repair suggestions, reducing guesswork and shop visits.
