In today’s hyper-competitive car rental landscape, fleet efficiency isn’t just about keeping vehicles on the road. It’s about using data, automation and customer insights to drive profitability. Even seasoned fleet operators can make missteps that quietly erode margins, customer satisfaction and operational control.
Before diving into pitfalls and solutions, it’s important to understand the broader context: car rental is a dynamic, cyclical industry shaped by seasonal surges, fluctuating asset values and fast-evolving technology. Operators that fail to harness data, mismanage downtime, or overlook telematics risk falling behind competitors.
Let’s explore 5 fleet management mistakes holding your vehicle rental business back and how Coastr solves them
1. Neglecting Proactive and Predictive Maintenance
Many operators stick with reactive maintenance: fixing issues only when vehicles break down. This leads to costly unplanned repairs and downtime, estimated at $448 to $760 per vehicle per day.
In contrast, predictive maintenance powered by telematics and real-time data can drastically reduce this risk. Geotab reports that predictive maintenance helps minimise downtime, extends vehicle life and lowers hidden costs through early detection of worn components, efficient scheduling and avoiding unnecessary part replacements.
Why it matters: Downtime doesn’t just incur repair costs. It kills revenue and damages customer trust. Proactive planning ensures availability and reliability.
2. Failing to Right-Size and Optimise Fleet Capacity
Maintaining too many vehicles is a drag: excessive fuel, insurance, servicing and storage costs. Conversely, too few vehicles during peaks lead to overuse, skipped maintenance and poor service. Right-sizing based on demand and forecasts is key.
Real-world data underscores this: Avis Budget’s strategic fleet reduction believes in selling older vehicles and aligning supply with demand which led to a 23% stock surge, despite flat revenue. Their utilisation remained consistent with the previous year, demonstrating the power of smart fleet sizing.
According to Frost & Sullivan, operators that use demand-based fleet optimisation can cut idle inventory costs by up to 25%.
Why it matters: A fleet that’s just the right size cuts unnecessary costs, improves service quality and enhances asset lifecycles.
3. Underestimating the Cost of Downtime
Fleet downtime carries hefty hidden costs. Platform Science notes that idle vehicles cost operators US $448 – US $760 per day and not just through lost rental revenue but also customer dissatisfaction, driver frustration, reputation risk and even contractual penalties.
Moreover, an Arval survey found that 18% of fleets reported increased downtime over the past year which is a rising concern.
Deloitte research adds that downtime can slash annual profitability by up to 15% in rental fleets that lack automated maintenance and scheduling systems.
Why it matters: Downtime is more than just an operational nuisance; it’s a profit killer and brand eroder.
4. Lacking Visibility: Telematics, Tracking and Fraud Prevention
Fleet operators often struggle with poor visibility: not knowing where vehicles are, their status, or how they’re being used. This disrupts routing, scheduling, safety and cost control.
The American Car Rental Association emphasised at a recent industry event that integrating telematics into rental systems is vital for theft prevention, faster vehicle recovery and better availability management.
A 2024 Telematics Wire report found that fleets using GPS tracking experienced 25% higher customer satisfaction and 40% faster recovery of lost or stolen vehicles.
ABI Research also predicts that over 75% of fleet operators will increase investment in telematics by 2026.
Why it matters: Without real-time tracking, inefficiencies multiply - lost vehicles, misuse and fraud slip through the cracks, hurting both security and ROI.
5. Relying on Manual Processes and Disconnected Systems
When bookings, maintenance and billing data sit in silos, operators lose visibility and agility. Manual entry leads to errors, delayed reporting and missed opportunities for optimisation.
Fleet Management Weekly notes that businesses digitising fleet operations achieve up to 20% higher utilisation and 15% lower administrative costs.
Why it matters: Disconnected systems slow decision-making and hide performance insights.
