Maintaining a used electric car: what is still on the schedule

A fully electric vehicle has no combustion engine, no engine oil and no exhaust system. Natural Resources Canada presents it as an option for anyone who wants to cut fuel and maintenance spending sharply. Engine oil changes, spark plugs and the engine oil filter disappear from the schedule.

The remaining maintenance list is shorter, but it is not empty: the three manufacturers whose Canadian documents we read all schedule a periodic visit (brakes, suspension, 12 V battery, tire rotation), the cabin air filter, brake fluid, reduction gear oil and coolant. What changes from one model and model year to the next is the timing.

We compared the normal maintenance schedule intervals in the Canadian documents of three manufacturers, consulted on October 4, 2026: Kia Canada's owner's manuals for the 2020 Niro EV, the 2024 Niro EV and the 2023 EV6, Hyundai Canada's maintenance schedule tool, and Nissan Canada's 2023 LEAF owner's manual. Each interval applies at whichever comes first, kilometres or months.

Two takeaways. First, the same model name can hide two schedules: the first-generation Niro EV and the second-generation one share neither the same basic service nor the same coolant interval. Second, this table covers the model years we verified, not the others: for the unit you are considering, the reference remains the schedule in its own manual or in the manufacturer's tool.

An EV still has a cooling system, but what it cools varies from one model to the next. In the 2023 LEAF manual, Nissan specifies that its coolant protects the electrical equipment “such as the motor and the inverter.” In the 2020 Niro EV manual, Kia asks that top-ups be left to a Kia dealership, using a coolant specified for electric vehicles; Hyundai refers to a “low-conductivity” coolant.

This is where maintenance records matter when buying used. Depending on its in-service date, a 2021 Kona Electric or a 2020 Niro EV has already passed at least one 36-month deadline. Ask for the replacement invoice: a low-mileage unit is not exempt, since the interval is also counted in months. If the invoice does not exist, get the job priced before negotiating rather than after.

Regenerative braking spares the pads, but the manufacturers do not conclude that the brakes can wait. Hyundai's schedule for the 2021 Kona Electric lists a front and rear brake service, parking brake included, from 24,000 km or 24 months, then at every 24,000 km visit. Kia calls for an inspection of the discs, pads and calipers at every visit on the 2024 Niro EV, and more often under severe conditions.

Nearly new pads do not eliminate the need for this replacement: on a four- or five-year-old vehicle, check the service records to confirm it was done.

Tires. In Quebec, winter tires are mandatory from December 1 to March 15, according to the Government of Quebec. Rotation is part of every basic service in the schedules compared, every 12,000 or 13,000 km depending on the model. In its electric vehicle maintenance tips, Kia points out that correct pressure helps range. Since pressure drops with temperature, check it as soon as the first cold snaps arrive.

The 12 V battery. An electric vehicle keeps a small 12 V battery for its on-board systems, and every schedule compared calls for it to be checked. The 2024 Niro EV manual even describes a jump-start procedure with a booster battery, as on a gasoline vehicle. The 2023 LEAF manual warns that repeated use of the charging timer once charging is complete can drain the 12 V battery. When buying, ask when it was tested or replaced.

Each manufacturer publishes a second, tighter schedule for severe conditions. In the 2024 Niro EV manual, Kia includes driving in areas where salt is used or in very cold weather, salted roads and trips under 16 km in freezing temperatures. For the 2023 LEAF, Nissan includes roads where salt has been spread and repeated trips under 16 km below freezing.

On the 2024 Niro EV, the reduction gear oil then goes from an inspection to a replacement every 117,000 km; on the 2023 LEAF, brake fluid replacement is due at 24,000 km or 12 months. Ask the shop which schedule the vehicle followed, and which one suits your driving.

A used EV is judged on what can be proven. Five checks, in order:

For the full process, see our guide to buying a used electric vehicle, and our article on extended warranties if the original coverage is nearing its end.

On each listing, first find the exact model year: it tells you which manufacturer schedule to consult, and therefore which invoices to ask for.

Also browse all available Nissan LEAF and Hyundai Kona Electric models, or filter by city: EVs in Sherbrooke, EVs in Drummondville, EVs in Granby.

For servicing in the region, the network includes Kia, Nissan and Mitsubishi dealerships in Drummondville, Nissan and Mazda dealerships in Saint-Hyacinthe, and a Nissan dealership in Victoriaville. Hyundai is represented in Magog. Before booking an appointment for a battery-related item, ask whether the shop is equipped and trained for the brand's EVs. Groupe Beaucage also offers prepaid maintenance plans for new or used vehicles: have them specify which items apply to an EV, since the page also lists services specific to gasoline engines.
