Knight’s Mobile Auto Maintenance & Repair brings professional diagnostic equipment and practical troubleshooting to your vehicle wherever you are in Chesapeake. Owner Marvin Knight performs OBD-II scans, battery and starter testing, charging-system analysis, and electrical circuit checks on-site to pinpoint faults quickly and recommend the most efficient repair path.

We serve neighborhoods across Chesapeake — Greenbrier, Great Bridge, Deep Creek, South Norfolk and Western Branch — and operate near local landmarks including Great Dismal Swamp access points, Chesapeake Square, and the Great Bridge Battlefield. For drivers stuck at home, at work, or along a city thoroughfare, we provide a clear diagnosis, written findings, and options for same-day parts pickup and installation to get you back on the road with minimal downtime.

Diagnostics cover engine management lights, intermittent stalling, starting problems, erratic charging, sensor failures, and many electrical gremlins. When a fault points to a component replacement, Knight’s sources parts same day whenever possible and will return to complete the repair if you authorize it.
