Electric vehicles (EVs) have different maintenance requirements from gas-powered cars, but following a proper maintenance schedule remains crucial for preserving performance, safety, and long-term value. This guide provides a comprehensive overview of everything you need to know about caring for your EV9.
Why EV9 Maintenance Differs From Gas-Powered Kias

EVs have different maintenance needs than gas vehicles. To start, they don't have combustion engines, so the need for oil changes is eliminated. An EV has about 20 to 25 moving parts in its drivetrain, while a gas car can have anywhere from 200 to 2,000 or more. Fewer parts mean there's less potential for something to go wrong.
The EV9's regenerative braking system converts the kinetic energy generated during braking into electricity, which is stored in the battery. This system reduces wear on regular brake parts, giving you longer-lasting pads and rotors. However, brake fluid must still be replaced every three years, regardless of the mileage, as it absorbs moisture over time. The battery-cooling system fluid and the reduction gear fluid also require regular checks.
The tires on EVs, such as the EV9, endure more strain due to their heavier battery packs and greater torque requirements. The immediate power delivery in EVs can cause tires to wear out more quickly, so you'll need to rotate them more frequently and check the pressure more often than with traditional cars.
Complete Kia EV9 Maintenance Schedule by Mileage
The EV9 follows a straightforward 8,000-mile service pattern. Your first visit includes a tire rotation (Kia recommends this every 8,000 miles or sooner if you notice uneven wear) and a thorough inspection of all major systems.
At 16,000 and 32,000 miles, you'll need to replace the cabin air filters and check the reduction gear fluid. At 48,000 miles, key fluids are replaced. At the 120,000-mile mark, your EV9 will require more significant maintenance, such as battery coolant system maintenance. Each service will also include a thorough inspection of the safety systems, electrical components, and overall condition of your EV9. These checks help to maximize your EV9's performance and longevity.
Kia EV9 Maintenance Costs Breakdown
A report by the U.S. Department of Energy found that the estimated scheduled maintenance cost for EVs is 6.1 cents per mile compared to 10.1 cents for gas vehicles. That difference amounts to substantial savings over time. For example, if you drive 30,000 miles in a gas car, you'll pay $3,030 in scheduled maintenance but just $1,830 if you drive the same distance in an EV.
While EVs require less maintenance, labor rates can be higher than those for traditional cars due to the specialized knowledge required for EV systems. To save money, it's always advisable to shop around for basic services. However, for repairs and maintenance on high-tech EV parts, you'll need properly trained technicians, such as our team at Huffines Kia Corinth. We regularly offer discounts and service specials to help you reduce your Kia maintenance costs.
What Your EV9 Warranty Covers
Kia backs the EV9 with solid warranty protection. You get a 10-year/100,000-mile powertrain warranty and a five-year/60,000-mile bumper-to-bumper warranty. For EV-specific components, Kia offers a 10-year/100,000-mile EV battery warranty that covers repairs or replacements of battery components. That's valuable coverage for the priciest part of your EV.
Your warranty also adds value when selling, as Kia warranties can be transferred to new owners within the coverage period, helping to boost the vehicle's resale value. To preserve warranty protection, it's essential to follow the Kia service schedule.
DIY vs. Kia Dealership Maintenance
You can tackle many routine EV9 maintenance tasks at home, including changing the cabin air filter, checking tire pressure, topping off the washer fluid, and performing basic visual inspections. This can save you a significant amount of money if you're mechanically inclined. However, any work on high-voltage systems, battery testing, or coolant service must be done by a certified technician. Working on these components without proper training is dangerous and can void your warranty.
Kia dealerships have the right tools and trained staff to properly maintain hybrids and EVs. You can discuss with our certified service center what's safe versus what requires professional attention.
How To Track Your EV9 Service Schedule
Keeping up with EV9 maintenance is simple with today's technology. Your vehicle's built-in reminder system alerts you when service is due with messages on your dashboard or screen. The Kia app also offers service tracking, helping you monitor upcoming needs and book appointments. These digital tools make staying current with service incredibly easy, eliminating the need for manual mileage tracking. However, it's essential to schedule regular appointments in advance to avoid missing important service intervals.
Don't forget that maintaining good records can help with warranty claims and improve your vehicle's resale value. Always document every service, whether performed at a dealership or as a DIY project, with notes on the date, mileage, and the specific work performed.
