Car Maintenance List: Complete Checklist by Mileage & Time

Many EV owners assume fewer moving parts mean minimal maintenance. This complete checklist breaks down required service by time and mileage for EVs to help you maximize your vehicle’s lifespan.

Why Is Car Maintenance Important?

Many car owners have a misconception: since electric vehicles have fewer moving parts, they require almost no maintenance. Although electric vehicles do away with the complex mechanical structure of internal combustion engines, having fewer parts does not mean they require no maintenance at all.

Unlike gasoline-powered vehicles, electric vehicles do not have an engine, fuel supply system, or exhaust treatment system. However, there are still many critical components that require regular maintenance:

• Battery pack and associated thermal management system
• Drive motor and power electronics unit
• Complete braking system
• Tires and tire pressure monitoring system
• Suspension, steering, and chassis components
• Heat pump air conditioning system
• Wear-and-tear body components such as headlights and windshield wipers

As mileage increases, mechanical components undergo normal wear and tear, and consumables such as coolant and brake fluid gradually degrade. Therefore, electric vehicles also require regular maintenance to:

• Ensure driving safety
• Protect the battery, motor, power electronics, and other high-voltage components while helping maintain consistent driving range
• Avoid costly repairs
• Extend the vehicle’s service life
• Maintain resale value
• Optimize the driving and riding experience

Monthly Car Maintenance Checklist

Even though electric vehicles have a simpler mechanical structure, simple monthly self‑inspections remain essential.

Check Tires and Tire Pressure

Inspect tread and sidewalls for bulges, cracks, punctures and uneven wear, and set tire pressure to manufacturer specifications. EV batteries add weight and deliver high torque, placing extra load on tires. Incorrect pressure accelerates wear, raises energy use and weakens braking. Confirm your tire‑pressure monitoring system works correctly.

Check Lights and Safety Features

Test headlights, turn signals, brake lights and parking lights. Quickly verify seat‑belt and door‑lock operation for basic driving safety.

Check Windshield Washer Fluid and Wipers

During your monthly inspection, top off the windshield washer fluid and check the wiper blades for cracks or streaks left after wiping. Replace the wiper blades promptly if the rubber blades show signs of wear.

Inspect Charging Equipment

Check charging cables and connectors for wear and corrosion. Inspect plug contacts for burn marks and housing for dents. Stop use immediately if you see overheating or smell burning, and consult a professional. Never disassemble charging hardware yourself.

Braking System

Inspect the brake pads and rotors for wear. Pay attention to the brake pedal feel during daily driving, and watch for unusual noises, vehicle vibration, or a spongy pedal. If any of these issues occur, take the vehicle to a repair facility for inspection promptly.

EV Maintenance Around 5,000 Miles

Electric vehicles do not require oil changes, but their weight and the high torque of the electric motor can accelerate wear on certain components, so professional maintenance should be performed based on mileage.

Tire Rotation

Rotate the four tires to balance tread‑wear rates. Check tread depth and inspect for damage including bulges, cracks, and punctures. This practice improves ride comfort, slows tire aging, and extends tire service life.

Brake Inspection

Assess actual wear on brake pads and rotors, check brake lines for aging or leaks, and test brake‑pedal feel to confirm mechanical braking performance meets standards.

Regenerative Braking Inspection

Verify proper activation of energy recovery during deceleration, check for smooth regenerative‑braking output, and troubleshoot reduced recovery efficiency or faults to ensure seamless coordination with mechanical brakes.

Chassis Inspection

Examine chassis skid plates and protective housings for dents or deformation, verify high‑voltage cover mounting and tight fasteners, and resolve safety risks caused by chassis scrapes.

EV Maintenance Around 15,000 Miles

Battery and Cooling System Inspection

Check battery coolant level and cooling circuit for leaks, inspect cooling hoses for aging or bulging wear, and pull BMS data to evaluate battery‑module operating condition.

Cabin Air Filter Maintenance

Inspect the cabin air filter for dirt and blockages. Replace heavily soiled filters to preserve cabin air quality and prevent restricted AC airflow or unpleasant interior odors.

Annual Maintenance for Electric Vehicles

Electric vehicles have fewer moving parts than gasoline-powered vehicles, but they still require professional annual inspections. Even if your annual mileage is low, it’s important to promptly check for non-mileage-related issues such as aging and corrosion:

Comprehensive Battery System Inspection

Check the fluid level in the battery cooling system and inspect for leaks in the piping, read battery health and cell temperature differential data via the BMS, and inspect the battery pack housing for any impact damage.

Brake Fluid Inspection and Replacement

Check the brake fluid level and moisture content; brake fluid absorbs moisture and degrades over time, regardless of mileage. When the manufacturer’s specified service interval is reached, drain the old fluid, refill with new fluid, and bleed the lines to prevent air locks from affecting braking performance.

Electric vs. Gas vs. Hybrid: Maintenance Comparison

Vehicles powered by internal combustion engines require:

• Regular oil and oil filter changes
• Replacement of air filters and fuel filters
• Inspection or replacement of spark plugs and timing components
• Maintenance of engine coolant and inspection of the exhaust system
• Regular replacement of transmission fluid and differential fluid

Electric vehicles still require:

• Tire inspections, rotation, wheel alignment, and replacement
• Brake pad and rotor inspections, as well as brake fluid checks and replacement
• Cabin air filter replacement
• Inspections of the battery pack housing, coolant level, and circuit leaks
• Reading BMS data to monitor battery module operating status
• Checking the charging port for burn marks and foreign object buildup

Seasonal Maintenance Tips for Electric Vehicles

Extreme temperatures can affect electric vehicle batteries and range, so specialized inspections should be conducted according to the season.

Winter

• Battery performance decreases in cold weather; prioritize charging in a garage and enable battery preheating to improve charging efficiency.
• Check the coolant level, inspect for leaks, and ensure the thermal management system is functioning properly.
• Tire pressure tends to drop in cold weather; calibrate it promptly to reduce energy consumption and abnormal tire wear.
• Check the cabin air filter and test the HVAC heating function.
• For long‑term parking, keep the battery at a moderate charge; avoid full or zero‑percent storage.

Summer

• Ensure the cooling system is functioning properly. Avoid fast charging immediately after exposure to direct sunlight to reduce thermal stress on the battery.
• Check for signs of overheating or burn marks.
• High temperatures accelerate rubber aging; inspect for cracks, monitor tire pressure, and prevent tire blowouts.
• Park in shade when possible and keep the battery at moderate charge.
