Operational results, grounded in the real world.

Challenges Faced
A large commercial fleet operator was experiencing frequent unplanned breakdowns that disrupted delivery schedules and created high emergency repair costs. Faults were only discovered when vehicles stopped working, leaving maintenance teams in a reactive cycle with no advance warning.
Solution Implemented
Suntotal deployed OBD telematics across the fleet, enabling real-time fault code monitoring, engine health alerts and vehicle-level diagnostic dashboards. Maintenance teams received automated notifications the moment a fault code was triggered, with severity classification to help prioritise action.
Results Achieved
Unplanned breakdowns dropped significantly within the first quarter. Maintenance teams shifted from reactive repairs to scheduled interventions, reduced emergency call-out costs and extended the operational life of key vehicles across the fleet.
