A vehicle that breaks down mid-trip does not just cost you the repair; it costs you a late customer, a rescheduled driver and perhaps a replacement vehicle. Yet in many companies maintenance is still run from memory or a sticker on the windscreen. This article explains how to build a preventive maintenance system for your fleet: what to record, when alerts should fire and how to use the data in your decisions.
Reactive versus preventive maintenance in practice
Reactive maintenance means repairing a vehicle after it breaks down. You do not know when it will happen, and it usually comes at the worst time.
Preventive maintenance means scheduled inspection and service by distance or time, to catch small problems before they grow. It does not eliminate breakdowns entirely, but it makes most stoppages planned, at a time you choose.
The realistic goal is not zero breakdowns; it is knowing the condition of every vehicle and having service dates known in advance to operations.
What to record for each vehicle
- Basic data: model, year, plate number, VIN and fuel type.
- Odometer readings: regularly, because most service intervals are distance-based.
- Maintenance plan: the periodic items and the interval for each, by distance or time, based on the manufacturer's recommendation and your operating conditions.
- Work log: every service or repair with its date, odometer reading, parts replaced, cost and workshop.
- Documents: registration, insurance and periodic inspection with expiry dates.
How the schedule is built
By distance
Oil and filter changes and brake checks, for example. This needs reliable odometer readings, either from the driver via an app or from a tracker if you have one.
By time
Some items depend more on time than distance, such as certain fluids and the battery, as well as documents and periodic inspection.
Whichever comes first
The practical approach is to give each item both a distance limit and a time limit, and to alert when either is reached first.
Alerts: when, and to whom?
An alert that arrives late or goes to the wrong person is useless. Define:
- Enough lead time: a distance or number of days before the due point that allows workshop booking without disrupting trips.
- Recipients: the maintenance owner first, and operations too, so the vehicle is not assigned a trip on its service day.
- Escalation: if a vehicle passes its due point with no service recorded, management is alerted.
Connect maintenance to operations
The biggest benefit appears when the person assigning trips can see maintenance status. A vehicle that is due for service is not sent on a long trip, and a vehicle in the workshop does not show as available. That link is what turns maintenance from a separate file into part of fleet management. For the full picture, see our fleet management system buyer's guide.
Fault reports from drivers
Drivers are the first to notice a strange noise or a warning light. Give them a simple way to report from their phone with a photo and description, so the report becomes a work order the maintenance owner follows to closure. Verbal reports tend to get forgotten.
Use the data in decisions
| Question | Data that answers it |
|---|---|
| Which vehicles cost most to maintain? | Total maintenance cost per vehicle over a period |
| Do certain faults recur? | Repairs classified by type and model |
| Is the external workshop working well? | Time in the workshop and repeat repairs |
| Is it time to replace a vehicle? | Maintenance plus fuel cost compared with similar vehicles |
Neglected maintenance also raises fuel consumption, so read this alongside practical levers to cut fuel costs.
Getting started
- Enter every vehicle with its latest odometer reading and last known service.
- Define a maintenance plan per model by distance and time.
- Enter document expiry dates.
- Set alert recipients and lead times.
- Ask drivers to record odometer readings regularly.
- Review the maintenance report monthly with operations.
In Maham Fleet
Maham Fleet keeps a record for each vehicle with its documents and odometer readings, with maintenance and document-expiry alerts, alongside driver licence expiry alerts and a driver app. If you run an in-house workshop or have particular maintenance procedures that need a different system, that can be scoped as a custom system.
FAQ
Where do I get the right service intervals?
From the manufacturer's manual first, then adjusted for operating conditions such as heat, dust and loads, in agreement with your workshop.
Do I need a tracker for odometer readings?
No. A driver recording the reading with a photo in the app on a regular basis is enough. A tracker makes it automatic.
How do I handle several external workshops?
Record each work order with the workshop name, cost and duration, and compare them with data after a while.
