EV vs ICE Maintenance Costs: What Fleet Operators Need to Know in 2026

With more shippers demanding zero-emission transport and new incentives making electric vehicles increasingly attractive, Canadian fleet operators are accelerating their shift toward electrification. But one question continues to come up: how do EV maintenance costs really compare to gas and diesel vehicles, and what does the difference mean for your annual maintenance budget?

The short answer is that electric vehicles require less maintenance than gas powered vehicles, and the savings are significant. While the upfront cost of electric trucks can be higher, the total cost of ownership often tilts in favour of EVs thanks to lower scheduled maintenance costs, fewer breakdowns, and reduced fuel costs over time. This post breaks down where those savings come from and what fleet operators need to budget for.

EV vs Gas Vehicle Maintenance Costs: What the Data Shows

EVs consistently outperform gas and diesel vehicles when it comes to service, maintenance, and repair expenses. EV maintenance costs are lower across every commercial vehicle class studied.

A Consumer Reports study found that EV owners and ev drivers pay about half as much for maintenance and repairs compared to gas car and ICE vehicle owners. That trend holds for commercial fleets too.

According to the International Council on Clean Transportation (ICCT), battery electric trucks have the lowest per-mile maintenance costs of any powertrain:

• Battery-electric: $0.176 per mile
• Diesel: $0.246 per mile
• Natural gas: $0.298 per mile

These numbers add up fast across large fleets, often delivering thousands of dollars in savings per vehicle per year. For fleet operators, the electric vehicle maintenance costs advantage is not marginal. It is structural.

Why Electric Vehicle Maintenance Costs Are Lower

What Gas Engines and ICE Powertrains Require

To understand why EV maintenance costs are lower, it helps to compare the mechanical complexity of each powertrain. A traditional internal combustion engine in gas powered vehicles relies on thousands of moving parts including spark plugs, a multi-speed transmission, complex gas engines with fuel systems, and a full exhaust system with catalytic converters and mufflers. Gas cars and diesel vehicles require regular oil changes, fluid top-ups including windshield washer fluid, exhaust system inspections, and eventual replacement of specialized components across the drivetrain.

Battery electric vehicles use a single electric motor with far fewer moving parts. There is no fuel system to service, no spark plugs to replace, no exhaust system to inspect, no transmission fluid to change, and no gas station visits required. This fundamental difference is the primary reason EVs deliver consistently lower scheduled maintenance costs over their lifetime.

Fewer Moving Parts Mean Lower Regular Maintenance

EVs can have as few as 20 moving parts compared to 2,000 or more in gas powered vehicles. This means:

• No oil changes
• No spark plugs or timing belts
• No exhaust systems or catalytic converters
• No transmission fluid or coolant flushes as part of regular maintenance
• No windshield wiper blades linked to engine systems

Fewer parts result in fewer breakdowns, less regular maintenance, and lower additional costs per vehicle per year. EV compared to ICE vehicles, the maintenance schedule is simpler and more predictable across the board.

Regenerative Braking Reduces Brake Wear

Regenerative braking systems recover energy during deceleration and reduce wear on brake pads and rotors. Volvo's VNR Electric recovers up to 15% of braking energy, extending both range and component lifespan. Brake pads in electric vehicles typically last two to three times longer than in gas powered vehicles, reducing scheduled maintenance costs significantly on high-mileage fleet vehicles.

EV Battery Maintenance and Battery Life

While high voltage batteries are the most expensive EV component, they require very little battery maintenance in day-to-day fleet operations. Most EV battery packs carry 8 to 10 year warranties. Real-world fleet data from Geotab shows EV batteries degrade at approximately 2.3% per year under typical fleet conditions, and many batteries lose capacity slowly enough to last 15 or more years. Regular battery system checks through telematics ensure battery health is monitored without the need for invasive servicing. In extreme temperatures, batteries lose capacity more quickly, making thermal management a key part of battery maintenance for Canadian fleets.

Battery chemistry in modern EVs is also improving. The price of lithium-ion battery packs has dropped over 80% since 2010, with further decreases expected, reducing the long-term cost of ownership further.

What Still Needs Maintenance on an EV

Despite their lower overall maintenance burden, EVs are not maintenance-free. EV owners and fleet operators still need to budget for:

Tires and Tire Wear

EVs typically carry extra weight due to their battery packs, leading to faster tire wear, particularly on front axles. Instant torque delivery also accelerates tread wear during aggressive acceleration. EV tires are engineered for load and efficiency, but they require more frequent rotation intervals than equivalent gas vehicle tires. Monitor tire pressure regularly, as under-inflation compounds tire wear on heavier electric vehicles.

Brake Fluid and Hydraulic Systems

While regenerative braking reduces wear on brake pads and rotors, hydraulic systems still need inspection. Brake fluid can degrade with heat and moisture over time, and calipers and ABS modules require routine checks as part of a scheduled maintenance program.

Thermal Management and Cooling Systems

Modern EVs use liquid cooling loops to maintain optimal battery temperature. These systems include radiators, coolant pumps, heater cores, and thermal valves. Inspect coolant levels and monitor pump performance using EV telematics. In extreme temperatures, cooling system health directly affects battery life and electrical system reliability.

HVAC, Windshield Wipers, and Cabin Filters

EVs rely on electric heating and cooling systems. Cabin filters, windshield wipers, and windshield washer fluid all require regular maintenance on the same schedule as gas cars. Ensure proper filter maintenance for air quality and inspect the electric compressor system in high-usage vehicles.

Chassis and Suspension

These components are shared with gas powered vehicles and subject to the same wear patterns, particularly for fleets operating in Canadian winters or on rough terrain.

Real-World EV Maintenance Savings for Commercial Fleets

The cost benefits of EV maintenance are playing out in real-world operations. According to the U.S. Department of Energy, battery-electric buses show a 43% reduction in maintenance costs compared to diesel vehicles. For Class 6 to 8 commercial vehicles, reduced maintenance and operational efficiencies are already improving margins before full-scale fuel savings compound the advantage.

Municipalities and public utilities running medium-duty electric vehicles have reported fewer service calls, lower parts inventory needs, and reduced technician hours per vehicle ev compared to equivalent gas powered fleets.

Tips for Reducing Fleet Maintenance Costs After Switching to EVs

Upskill Your Workforce

EVs come with unique diagnostic systems, high voltage batteries, and specialized components that require targeted training. Natural Resources Canada (NRCan) offers a national EV technician training platform developed with industry associations and technical colleges, covering diagnostics, safety protocols, and high-voltage component servicing.

Adapt Scheduled Maintenance Schedules

EVs require less frequent service but different types of inspections. Shift focus from gas engines diagnostics to electrical system health, battery system checks, and thermal management. Schedule fewer but more targeted checkups following the owner's manual and OEM recommendations. Use telematics to monitor battery health, regenerative braking system performance, and cooling system status in real time.

Work with a Specialized Electrification Partner

EVs bring new complexity in warranties, telematics, charger maintenance, and OEM servicing schedules. Leasing with an EV-focused partner like 7Gen means 24/7 support and remote diagnostics, embedded service, maintenance, and repair tracking in every lease, and preventative maintenance included in select regions.
