What owners say
Aggregated from UK owner forums and communities - the things you only learn after living with the car.
Shared watch-outs for both cars
Owners of every car here flag real-world range, dealer & service support. Worth checking on a test drive whichever you choose.
Hyundai IONIQ 5 N
Base
Owners love
- Owners and enthusiasts call it the most engaging electric car to drive, with sharp steering and handling that hides its weight.
- The simulated gearshifts (N e-shift) and engine sounds are widely praised as fun rather than a gimmick.
- Fast 800-volt charging makes a 10-80% stop about 18 minutes, which owners say matters more than range.
Watch out for
- Efficiency is poor: owners report 2.2 to 2.7 miles per kWh, or about 190 miles in winter and 220 to 235 in summer.
- Tyres wear fast when the performance is used; one owner's first set lasted about 12,000 miles at around 250 pounds a corner.
- It is big and heavy for a performance car, with a wide turning circle.
Owner tips
- Budget for tyres and brakes, and ask how the car has been driven.
- Use the satnav to precondition the battery before a rapid charger.
Kia EV9
Air
Owners love
- Owners love the space: seven proper seats, a big boot and a calm, comfortable cabin for long family trips.
- It charges quickly, holding high power to about 80% on an 800-volt rapid charger.
- Owners report about 300 miles in mild weather, enough to make long journeys easy.
Watch out for
- Several owners report early electrical faults, most often a 12V battery that drains overnight and leaves the car dead.
- When faults need parts, owners report long waits at dealers and poor after-sales support, including a few battery-module repairs that took months.
- Smaller niggles recur: tyre-pressure warnings, parking-sensor faults and software glitches.
Owner tips
- Ask whether the car has had any 12V battery, sensor or battery-module work, and see the invoices.
- Check every camera, parking sensor and the tyre-pressure display before you buy.

Frequently asked questions
Which is cheaper to own over 5 years, the Hyundai IONIQ 5 N or the Kia EV9?
The Hyundai IONIQ 5 N is £845 cheaper to buy. Running costs are almost identical - about £192 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Hyundai IONIQ 5 N comes out roughly £765 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Hyundai IONIQ 5 N and Kia EV9 like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 232 miles for the Hyundai IONIQ 5 N and 291 miles for the Kia EV9 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV9 goes roughly 59 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 24-27 minutes.
Which is easier to park and drive in town, the Hyundai IONIQ 5 N or the Kia EV9?
The Hyundai IONIQ 5 N is the easier car for tight UK car parks: it is 40 mm narrower than the Kia EV9. In a standard 2,400 mm bay that leaves about 460 mm of total clearance for the Hyundai IONIQ 5 N and about 420 mm of total clearance for the Kia EV9. The Hyundai IONIQ 5 N also turns in a 0.3 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the Hyundai IONIQ 5 N or the Kia EV9?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Hyundai IONIQ 5 N and 89% for the Kia EV9. That is close enough that capacity loss should not decide between them. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation. The Hyundai IONIQ 5 N has the longer battery warranty at 8 years, versus 7 for the Kia EV9.
