Performance flagship of the E-GMP platform, sharing mechanicals with the Hyundai Ioniq 5 N and a close relative of the Porsche Taycan 800V architecture. The GT delivers 585 hp and 0-100 km/h in 3.5 seconds through dual motors, an electronic limited-slip differential, and Michelin Pilot Sport 4S on 21-inch wheels. It carries Kia's long 7-year/150,000 km vehicle warranty and 7-year/150,000 km battery coverage in Europe, which is still active on most used examples.
Strong 7-year Kia warranty still active
800V charging and mature E-GMP platform
ICCU failure risk across whole E-GMP
Tire wear on 21-inch is brutal
Buy if: You want supercar-level acceleration with usable range, long warranty protection, and accept higher-than-average EV running costs from 21-inch performance tires.
Avoid if: You are outside warranty with high mileage, cannot verify the ICCU recall has been completed, or expect EV running costs similar to a normal Kia.

Common Problems
Faulty transistor damages the unit, blocks 12V charging and causes sudden loss of drive power · more· less
A known E-GMP platform defect covered by a Kia global recall. The ICCU converts high-voltage traction battery energy to charge the 12V battery; when a transistor fails, the 12V flatlines and the car drops into limp mode or loses drive power entirely, often without warning. Kia recalled approximately 63,000 EV6 vehicles worldwide (MY2022-2024) and owners report wait times of 2-6 weeks for replacement parts during peak backlog. The recall is free and should be completed via Kia dealer. Out of recall, replacement runs €2,500-5,500 including high-voltage fuse. Even post-recall and post-software-update, forum reports show repeat failures on the same cars. Verify the SA556 / RCRIT-24V200 recall has been performed before purchase.
Original 12V battery often fails within 12-24 months, sometimes replaced under warranty more than once · more· less
The E-GMP architecture runs the 12V battery harder than a typical car because the ICCU top-up cycle is conservative. Multiple forum reports of original AGM 12V batteries failing at 13,000-20,000 km, and replacement batteries failing again within another year. Symptoms include warning messages, failure to start/wake, frozen infotainment, and door handle malfunctions. An upgrade to a larger-capacity AGM battery helps. Usually covered under the 7-year warranty while active. Check battery test report and age of current 12V before purchase.
Whirring or clunking from the front motor disconnect mechanism, typically in Eco/Normal at 30-60 km/h · more· less
The AWD EV6 uses a front-motor disconnect clutch to save energy when cruising. Many owners report a whirring sound that oscillates with speed in Eco or Normal modes, disappearing in Sport or with max regen. Forum consensus blames the disconnect mechanism geometry. Kia has replaced front reduction gears and full front drive units on a minority of cars under warranty. Most cases are cosmetic noise only and do not progress; a smaller number require full front motor/gearbox replacement (€5,000-6,000 out of warranty). The GT runs dual active motors so the symptom can present slightly differently, but the underlying hardware is the same.
OEM 255/40R21 Pilot Sport 4S typically lasts 20,000-30,000 km with enthusiastic use · more· less
Not a defect but a running cost you must budget for. The 2,200 kg kerb weight, 740 Nm of torque, and staggered setup destroy tires faster than on any other EV at this price point. Forum reports typically cite 20,000-30,000 km on rear tires with mixed driving, and owners report around 30,000-45,000 km on fronts. A full set of four Pilot Sport 4S in 255/40R21 is €1,600-2,200 fitted in Western Europe. The eLSD concentrates wear on the inside edges of the rear tires — check tread depth across the full width, not just center.
Voltage fluctuation can disengage parking pawl, risk of vehicle rollaway when parked · more· less
Recall SC236 covers 2022 EV6 vehicles built 17 Nov 2021 - 7 Apr 2022. The shifter control unit can fail to hold the parking pawl if a voltage spike occurs while parked, allowing the car to roll on a slope. Fix is a free software update at a Kia dealer. Verify this recall has been completed via VIN before buying an early 2022 car — unperformed work is a safety issue and an MOT/TUV concern.
'Check LSD' warning from connector or CAN bus faults, sometimes overheating-induced · more· less
GT-specific hardware. Owners have reported 'Check Limited Slip Differential' warnings on the cluster from as early as 10,000-20,000 km. Kia dealers have traced most cases to loose connector pins at the differential motor causing CAN network errors, repairable by reseating or replacing the connector. Thermal events (track driving, repeated launches) can also trigger temporary disable until the unit cools. Rarely requires eLSD replacement, but in-warranty is important because out-of-warranty repair can reach €1,500 if the control module is involved.
Frozen screens, failed over-the-air updates, charging ports occasionally refuse sessions · more· less
Widespread across Ioniq 5 and EV6 from 2022-2023. Typical symptoms include black infotainment after cold boot, lost charging sessions on some DC stations, keyless entry glitches, and V2L outlet not powering. Most are resolved by Kia software updates SA416, SA513 and later OTA packages. A minority of cases require head-unit or charging-port assembly replacement (€600-1,200 out of warranty). Check that the car is running the latest software and test AC and DC charging during the viewing.
Strong warranty cushions genuine E-GMP weak points
The EV6 GT shares real platform issues with every E-GMP car — ICCU, 12V battery, and front motor disconnect — but Kia's 7-year warranty typically still covers them on used examples. The GT-specific risks are running costs (21-inch tire wear, performance brakes) rather than defects. Priority for buyers: verify ICCU and SCU recall completion, check 12V battery test report, inspect rear tire inner edges, and confirm warranty balance before signing.
Recalls and Technical Service Bulletins
ICCU failure — loss of drive power (2022-2024, recall SA556 / 24V-200)
Critical — verify completed
SCU parking mechanism rollaway (Nov 2021 - Apr 2022 build, recall SC236)
Verify completed
Various software updates for charging, infotainment and 12V management
Check latest software version at Kia dealer
Contact Kia with the VIN to verify all recalls and software updates have been completed. The ICCU recall is the highest priority — an unperformed recall can leave the car stranded.
Warranty Status
Kia vehicle warranty (7 years / 150,000 km)
Often still active — verify exact expiry from first registration date
High-voltage battery warranty (7 years / 150,000 km)
Covers >65% capacity retention, still active on most used GTs
Paint warranty (5 years)
May have expired on early 2022 cars
Rust perforation warranty (12 years)
Active on all examples
Kia's 7-year / 150,000 km warranty fully transfers to subsequent owners and is the single biggest reason to prefer a serviced, dealer-maintained EV6 GT. Verify the exact first registration date — a car registered in late 2022 still has roughly 3-4 years of coverage left at the time of purchase in 2026.
