EV Service FAQ

Your EV Service Questions, Answered

New to EV ownership? Wondering what your car actually needs? We've answered the most common questions we hear from EV owners every day.

General

General EV Service Questions

Can an independent shop service my EV?
Yes. Many EV maintenance and repair services do not require proprietary manufacturer tools. Tire service, brake service, brake fluid exchanges, cabin air filters, wheel alignment, 12V battery replacement, and general diagnostics can all be performed at an independent shop. As a nexdrive-certified centre, we've invested in the professional-grade EV diagnostic equipment and training to service all major makes.
Will servicing my EV at an independent shop void my warranty?
No. Under Canadian consumer protection law (and the Competition Act), a manufacturer cannot void your warranty simply because you had your vehicle serviced at an independent shop — as long as the work is performed to the manufacturer's specifications using the correct fluids, parts, and procedures. We document every service with your VIN on record and use manufacturer-specified materials.
How often does an EV actually need service?
EVs have fewer service intervals than gas vehicles, but they still need regular maintenance. Key items: tire rotation every 10,000–15,000 km (sooner for Tesla and high-torque models), brake fluid every 2 years (regardless of how the brakes feel), cabin air filter annually or every 20,000 km, 12V auxiliary battery every 3–5 years, and thermal coolant at manufacturer-specified intervals (typically every 5 years or 150,000 km).
Do EVs need oil changes?
No. Battery electric vehicles (BEVs) have no internal combustion engine and therefore no engine oil to change. However, plug-in hybrids (PHEVs) and full hybrids (HEVs) do still have a gas engine that requires regular oil changes on the standard schedule.
What fluids does my EV need?
While EVs eliminate engine oil, coolant for the engine, and transmission fluid, they still use: brake fluid (hydraulic), thermal management coolant (for battery, motor, and inverter), windshield washer fluid, and power steering fluid (if hydraulic). Some EVs also use gear reduction fluid in the drive unit. We check all applicable fluids at every service visit.
Are repairs covered by a warranty?
Eligible repairs using NAPA parts are backed by the NAPA Peace of Mind Warranty — 3 years or 60,000 km, whichever comes first. Coverage applies to the parts and labour on those specific repairs. Ask us at the time of service which items qualify.
Battery

Battery Questions

Is it normal to lose range over time?
Yes — all lithium-ion batteries degrade gradually over time and charge cycles. Most EVs lose 2–3% of capacity per year under normal use. Losing 10–15% capacity over 5 years is expected and generally acceptable. Significantly faster degradation may indicate a thermal management issue, unusual charging habits (frequent DC fast-charging above 80% SOC), or a cell balance problem worth investigating.
Should I charge to 100% every night?
Most EV manufacturers recommend setting your regular charge limit to 80% for daily use, and charging to 100% only when you need maximum range for a specific trip. Regularly holding the battery at 100% (especially in warm weather) accelerates degradation. Setting the charge limit to 80–90% in your vehicle app is the best habit for long-term battery health.
How do I know if my battery is healthy?
Your vehicle app or display shows an estimated range, but this is influenced by driving style, weather, and recent trips — it's not a reliable indicator of battery health. A proper battery diagnostic reads state-of-health (SOH) and cell voltage balance using professional scan tools. We offer standalone battery health assessments — useful for annual peace of mind or before purchasing a used EV.
Does cold weather damage my battery?
Cold weather temporarily reduces available range and charging speed — this is normal lithium-ion behaviour and is not permanent damage. Most EVs have a battery thermal management system that heats the battery before fast charging in cold conditions. Parking in a garage and pre-conditioning the vehicle before driving in cold weather helps minimize range reduction. Permanent degradation from cold is minimal on modern EVs with active thermal management.
Brakes & Tires

Brakes & Tires Questions

Do EV brakes last longer?
Brake pads typically last significantly longer on EVs — often twice as long as on a comparable gas vehicle — because regenerative braking handles most deceleration. However, brake rotors can actually corrode faster on EVs due to infrequent friction contact. And brake fluid still degrades on schedule regardless of how often the friction brakes are used. Most EV manufacturers recommend a brake fluid exchange every 2 years.
Why do EV tires wear faster?
EVs are heavier than equivalent gas vehicles (due to the battery pack) and produce all of their torque instantly. Both factors accelerate tire wear compared to a gas vehicle of similar size. Tesla, for example, recommends tire rotation every 10,000–12,000 km — significantly more often than the 12,000–15,000 km typical for gas vehicles. Proper rotation intervals and correct alignment are essential to maximizing tire life on an EV.
Do I need special tires for my EV?
Not necessarily — but EV-rated tires offer real advantages. They're built with higher load ratings (to handle battery weight), lower rolling resistance (to preserve range), and in many cases additional noise dampening (since the cabin is quieter without engine noise). Many OEM tire fitments on new EVs are already EV-rated. We can advise on the best replacement options for your specific vehicle and driving needs.
