Hyundai i30 N PD-FL2(PD) — Problems & Common Faults

The i30 N was Hyundai's first hot hatch, developed under the former BMW M boss, in dealers from November 2017 with 250 hp as the base car and 275 hp as the Performance, from 29,700 and 32,200 euros in 2018. The facelift came in May 2021 with 280 hp, a new turbo, a strengthened block and an optional eight-speed dual-clutch; the 250 hp base returned as a manual hatch from 32,950 euros, and the Fastback came only as a Performance. European production ended in February 2024, and Hyundai takes N electric from here. In a three-way test against the Golf GTI Clubsport and the Civic Type R it finished second, won on costs and residuals and earned praise for the most fun per horsepower; against the Clubsport 45 it is rawer and more aggressive, louder, with more understeer and lift-off oversteer.

Which one: For the road the base car is enough, no sprint difference could be measured; the Performance adds the limited-slip diff, 360 mm brakes, valve exhaust and 19-inch forged wheels and is the choice for the track, and more than 90 percent of buyers took it. Manual or DCT is taste: the DCT is quicker at 5.4 seconds, launches cleaner than any front-drive manual and costs 3,000 euros more; the tests call it sometimes well done, sometimes merely adequate, and the manual remains the livelier car. Avoid early-series 2017 and 2018 cars without proof of the replaced parts.

What breaks: First the early-series high-pressure fuel pump: 2017 and 2018 cars stalled with loss of power and no fault code, and the part took weeks to arrive; out of warranty a workshop quoted 4,750 euros in 2023 at 55,000 km for pump, rail and sensor, the pump alone around 1,900 euros. There is no German recall for it, and Australia recalled the 2017 to 2022 model years in 2026. Second the sixth gear that baulks on pre-facelift cars, with new synchro rings as the tuner's fix. Third the throttle body control: the biggest repair in the 100,000 km long-term test, cold-start jerking the warning sign, about 700 euros. Add rattling exhaust flaps on early cars, a hopping front axle cured by 80-euro engine mount bushes, a leaking turbo oil line, front discs after 50,000 km and, on the DCT, recall KBA 012715 for the electric gearbox oil pump on 2021 and 2022 cars. The long-term test closed with a grade of 2 minus, one breakdown and 0.27 euros per kilometre.

Test drive: Cold start with long cranking, jerking or two to three seconds of rev hang, loss of power without a fault code, a grinding sixth gear, a rattling flap. Oil level on the dipstick, because there is no electronic gauge and the pressure switch warns late; one car with 155,000 km needed two litres. Brake discs reveal the previous owner, chip tuning is common, Hyundai service book because of the five-year warranty, recall status on the DCT.

Market 2026: Pre-facelift Performance cars with 100,000 to 180,000 km at 14,000 to 17,000 euros, with under 70,000 km at 16,000 to 23,000 euros. Facelift cars from 2021 and 2022 with 75,000 to 145,000 km at 20,000 to 22,500 euros, from 2022 to 2024 with 12,000 to 50,000 km at 32,000 to 37,000 euros. The long-term test car fell from 39,980 to 19,650 euros in two years.

The buy: a facelift Performance manual with Hyundai service history, a clean cold start and no modifications. The car delivers more fun per euro than almost anything in the class, but asks for oil every 10,000 km, brakes and tyres in series and a previous owner who knew that.
