Is DIY Maintenance For Your Electric Vehicle Achievable?

by Jay Washington

As electric vehicles (EVs) soar in popularity, many owners are realizing the perks of owning these innovative and eco-conscious automobiles. Yet, with the thrill of driving an EV comes the duty of keeping it well-maintained and, if necessary, repaired.

Understanding the ins and outs of maintaining and repairing your EV holds significance for several reasons:

  1. Empowerment: Knowing how your EV works allows you to take charge of its maintenance, ensuring it remains in peak condition for years to come.
  2. Cost Efficiency: Basic maintenance tasks done by you can save both time and money compared to relying solely on professional mechanics.
  3. Informed Decision Making: Having knowledge about EV upkeep enables you to make informed decisions regarding your vehicle’s care, enhancing its longevity and performance.

What Maintenance Does Your EV Need?

Familiarizing yourself with how EVs function reveals their minimal maintenance demands compared to traditional internal combustion engine vehicles. Nonetheless, like any vehicle, EVs require regular attention to ensure top-notch performance and durability.

Battery Health Checks: The battery pack serves as the core of an EV, providing the necessary power for propulsion. Regularly monitoring the battery’s health is vital for preserving range and performance. Many EVs come equipped with built-in diagnostics for checking the battery’s state of charge and overall health.

Tire Maintenance: Proper tire care is crucial for safety and efficiency. EVs benefit from routine tire inspections, including checking tire pressure, tread depth, and overall condition.

Brake System Inspections: EVs utilize regenerative braking to slow down and recapture energy, which can reduce wear on conventional braking systems. Nevertheless, it’s important to periodically inspect brake pads and rotors for signs of wear and tear.

Coolant System Checks: EVs rely on cooling systems to maintain optimal operating temperatures for the battery, motor, and electronics. Regularly checking coolant levels and inspecting for leaks is crucial for preventing overheating and ensuring component longevity.

HVAC System Maintenance: The heating, ventilation, and air conditioning (HVAC) system in an EV are vital for passenger comfort and battery temperature regulation. Regular inspection and servicing of the HVAC system can help prevent issues and ensure efficient operation.

Basic DIY EV Maintenance Tasks

Despite the reputation of electric vehicles for simplicity and reliability, there are several basic maintenance tasks that EV owners can handle independently to keep their vehicles running smoothly.

Checking Tire Pressure: Use a tire pressure gauge to regularly check tire pressure, adhering to the manufacturer’s recommendations. Adjust pressure as needed and remember to check when tires are cold for accurate readings.

Topping Up Windshield Washer Fluid: Use appropriate windshield washer fluid that won’t harm the vehicle’s paint or wiper blades. If fluid levels are low, simply add more until reaching the appropriate level indicated on the reservoir.

Inspecting Brake Lights and Turn Signals: Regularly inspect these lights to ensure they function correctly. Replace any burnt-out bulbs promptly to maintain road safety.

Checking and Replacing Cabin Air Filter: Refer to the vehicle’s manual to locate and inspect the cabin air filter regularly. Replace it if it appears dirty or clogged, following manufacturer recommendations.

Inspecting Wiper Blades: Regularly inspect wiper blades for signs of wear or deterioration and replace them as needed. Periodically clean the blades to remove debris that could affect performance.

Safety Considerations For DIY EV Repairs

When working on your electric vehicle (EV), prioritizing safety is paramount. Here are some essential safety tips to keep in mind:

  1. High-Voltage Awareness: EVs employ high-voltage systems for motor power. Always assume exposed wires could carry electricity and be aware of their location.
  2. Protective Gear: Wear insulated gloves, safety goggles, and non-conductive footwear to guard against electrical shocks.
  3. Battery Precautions: Take precautions to prevent battery overheating or short circuits. Keep a fire extinguisher rated for electrical fires nearby.
  4. Vehicle Support: Ensure the vehicle is properly supported and stabilized before working underneath it using jack stands or ramps.

By adhering to these safety tips, you can confidently tackle DIY repairs on your electric vehicle while minimizing risks.

When To Seek Professional Help

While many EV maintenance tasks are feasible for home enthusiasts, certain situations warrant professional assistance:

  1. Complex Repairs: For intricate electrical systems or components beyond your expertise, consult a professional with EV experience.
  2. Safety Concerns: If unsure about safely handling a repair or encountering safety issues, seek help from a qualified professional.
  3. Specialized Equipment: Some repairs require specialized tools or equipment not readily available at home. Professional technicians have access to such tools, aiding in accurate diagnosis and repair.


Maintaining and repairing your electric vehicle (EV) can be fulfilling, but prioritize safety and caution when tackling DIY tasks. By familiarizing yourself with basic maintenance and adhering to safety protocols, you can confidently keep your EV running smoothly for years to come.
