Fleet maintenance software is a tool that helps businesses track, schedule, and manage the upkeep of their vehicles and equipment. Instead of relying on spreadsheets or paper logs, fleets can use a fleet maintenance software to automate critical maintenance tasks like preventive maintenance scheduling, vehicle diagnostics and health monitoring, work order management, driver vehicle inspection reports (DVIRs), reporting and analytics, and more.

Samsara Fleet Maintenance is an AI-powered, enterprise-grade Computerized Maintenance Management System (CMMS) built on real-time operations data that helps save time, increase asset utilization, and reduce maintenance costs. Most fleets manage maintenance across disconnected tools such as separate telematics, spreadsheets, and third-party invoicing workflows, creating gaps that lead to missed repairs, repeat shop visits, and high administrative overhead. Samsara’s Connected Maintenance eliminates these gaps by providing accurate, contextual, real‑time maintenance data in one platform, combining fault code intelligence, DVIRs, and operations data so every team member has full visibility into maintenance needs.

A Computerized Maintenance Management System (CMMS) is software that stores maintenance information and facilitates maintenance operations. With a CMMS system, maintenance teams can more effectively plan, track, and measure their physical assets, ensuring their equipment, facilities, and vehicles are maintained efficiently and reliably. 

Samsara is the only CMMS solution built on Samsara's AI. By harnessing the power of your fleet's data, you can save time and boost utilization, track costs for deeper insights, and consolidate systems for streamlined workflows. Samsara is a user-friendly platform engineered to minimize the time your vehicles spend in the shop and maximize their time on the road, directly impacting your bottom line.

Preventive maintenance follows a fixed schedule based on time or mileage, such as an oil change every 10,000 miles, regardless of a vehicle's actual condition. Predictive maintenance instead uses real-time data, like fault codes and engine diagnostics, to flag issues before they cause a breakdown. 

Fleet management software like Samsara leverages preventive schedules that trigger automatically based on engine hours, mileage, and fault codes, while AI fault code intelligence surfaces smart alerts with customizable action steps and cost estimates the moment an issue appears. Fraley & Schilling leveraged Samsara to reduce overdue preventive maintenance checks by 75%, keeping vehicles serviced on time and out of the shop for repeat visits.

Fleet maintenance costs are caused by repeat shop visits, missed preventive service, and administrative overhead from disconnected systems. By consolidating maintenance data so issues are caught early and grouped into fewer repairs, fleets can reduce operational costs, minimize maintenance spend, improve operational efficiency, and protect their bottom line.

Samsara’s fleet management software helps fleets reduce maintenance costs by reducing wrench time, minimizing vehicle downtime, optimizing wrench costs, and extending the vehicle lifecycle. For example, Maxim Crane was able to shift to a planned, predictive maintenance program, and as a result, they saved approximately $13 million in 2024—about $1 million per month in maintenance costs. Furthermore, Bramco leveraged Samsara’s AI-powered invoice automation to cut work order processing time from 20 minutes to under 2 minutes, saving over 400 hours annually.

Fleet maintenance software reduces vehicle downtime by helping teams move from reactive repairs to preventive maintenance. By leveraging real-time visibility, fleets can detect issues earlier, trigger automated reminders for preventative maintenance, accelerate work order creation, centralize maintenance records, and surface DVIR defects, vehicle faults, and scheduled maintenance items together. 

Samsara’s fleet maintenance software enables you to minimize unplanned downtime, reduce repeat shop visits, increase uptime, and maximize your bottom line. The City of Fort Lauderdale leveraged Samsara to see engine faults across their fleet in real-time and more quickly diagnose maintenance issues, unlocking a 28% reduction in vehicle downtime.

Samsara offers a unified fleet management solution that can handle both fleet tracking and maintenance. Samsara’s Vehicle Gateway plugs directly into the on-board diagnostic (OBD) port to collect GPS location data and engine data in real time. By connecting GPS vehicle tracking and fleet maintenance in a single dashboard, you can improve efficiency, reduce downtime, and minimize costs. With Samsara’s connected platform, fleets have access to advanced features such as:

• Real-time fleet tracking: Samsara gives teams live visibility into vehicle, trailer, and equipment location, plus trip history, geofences, and utilization data. GPS tracking data helps dispatch, operations, safety, and maintenance teams see what’s happening across the fleet in real time.

• Built-in vehicle diagnostics: Samsara surfaces engine diagnostics, fault codes, odometer readings, engine hours, idle time, and vehicle usage data alongside fleet location and driver behavior, giving teams a full operational picture rather than separate tracking and maintenance systems.

• CMMS maintenance capabilities: Samsara’s Fleet Maintenance solution is built on real-time operations data, providing teams full visibility into a fleet’s maintenance needs. It combines fault code intelligence, DVIRs, and operations data so teams can identify maintenance needs, prioritize repairs, and reduce missed issues.

Staying ahead of fault codes means catching diagnostic issues before they become roadside breakdowns. Fault codes, also known as diagnostic trouble codes (DTCs), are indicators used to diagnose malfunctions in a vehicle or piece of heavy equipment. While the malfunction indicator lamp (MIL)—also known as the check engine light—simply alerts drivers that there is an issue, a DTC identifies what and where the issue is. With a fleet maintenance software, you can proactively identify fault codes with automated alerts and preventive maintenance scheduling, enabling fleets to minimize downtime, improve operational efficiency, and ensure the health of their vehicles.  

Samsara uses AI fault code intelligence to surface codes as they occur, prioritize which ones need immediate attention, and generate customizable action steps with cost estimates, so anyone on the team, not just mechanics, can evaluate a fault and even challenge a third-party repair estimate. Fault codes flow directly into the same work order system as DVIR defects and scheduled maintenance, consolidating repairs instead of creating a separate alert to track manually.

Here are some common DTC codes fleets typically encounter, along with how Samsara can help you stay on top of them: P0442, P0606, P0101, P0110, P0500, P0420, P0300, P0455.

Fleet maintenance encompasses all activities that keep your vehicles operational and in good repair, including preventive maintenance, inventory management, asset tracking, asset management, route optimization, fuel management, compliance management, vehicle tracking, regular maintenance, and addressing breakdowns to control maintenance costs.
