Kia EV9 Problems: Common Issues and Repair Costs
The Kia EV9 is one of the most talked-about electric SUVs in the UK. It offers bold styling, seven-seat practicality, and long electric range. But as more drivers start using the EV9, some early issues have started to appear. In this guide, we’ll cover the most common problems owners are reporting and how much you can expect to pay for repairs and servicing in the UK.
1. Electrical System Failures – Dashboard Warnings and Power Loss
Some EV9 owners have reported worrying messages such as “Check Electrical Vehicle System” appearing shortly after purchase. In certain cases, the car becomes undriveable and needs dealer recovery.
One UK owner said:
“My EV9 has been at the dealer now for seven weeks with an electrical fault. There’s no fix date yet.”
Another added:
“When something goes wrong, you can be without the car for months. Kia has to fly in a corporate technician to diagnose it.”
Estimated UK repair cost: If out of warranty, diagnostics and electrical system repairs could range from £500 to £1,500, depending on the fault. Under warranty, these should be fixed at no cost, but wait times may apply.
2. Long Repair Delays – Not Costly, But Disruptive
Even if your issue is covered under Kia’s warranty, many owners report long delays for parts or technical diagnosis. Some say they’ve been without their vehicle for over two months due to parts shortages or limited EV9-certified technicians.
What this means for you: While it may not cost you money, being without a car for several weeks can be a major inconvenience. If you’re relying on the EV9 as a family or business vehicle, it’s worth having a backup plan.
3. Routine Servicing Costs – £200 to £400 Per Year
The EV9, like other Kia electric models, is cheaper to maintain than petrol or diesel SUVs. Most servicing includes basic checks, fluid top-ups, filter changes and software updates.
Owners of the EV6 report first-year service costs around £250, depending on the dealership.
UK estimate: Expect to pay between £200 and £400 per year for scheduled maintenance, depending on mileage and service plan extras.
4. Long-Term Repair and Maintenance Costs – About £4,400 Over 10 Years
According to long-term tracking data, Kia EV9 drivers can expect to pay around £4,400 over 10 years for all maintenance and occasional repairs.
This includes:
- Annual servicing
- Brake and tyre replacements
- Suspension work
- Minor electrical or hardware repairs
That works out to an average of £440 per year, which is less than what you’d typically spend on a diesel SUV of the same size.
5. Battery Warranty and Replacement Costs
Kia backs the EV9 with an 8-year or 100,000-mile battery warranty. This covers manufacturing faults and guarantees the battery won’t drop below 70 percent capacity during the coverage period.
Battery cost out of warranty: If you ever needed a full battery replacement after the warranty ends, it could cost £8,000 to £12,000, depending on labour and pack availability. Thankfully, this is very rare.

Final Thoughts
The Kia EV9 is a premium electric SUV with real presence and practicality. Most running costs are low, and the warranty is strong. But electrical issues, if they arise, can lead to frustrating delays even if they don’t cost money directly.
Before buying, check:
- Whether your local dealer has EV9-certified technicians
- What courtesy car or loan options are available
- How quickly your dealership can handle warranty claims
Overall, the EV9 remains a solid long-term choice, especially for families and drivers looking to go electric without giving up space or comfort.
