Hyundai Ioniq (Hybrid/PHEV)
Sold in the UK from late 2016 to 2022, the Hyundai Ioniq (AE) was the first car engineered from the outset to offer Hybrid (HEV), Plug-in Hybrid (PHEV) and pure Electric powertrains in a single 0.24 Cd five-door liftback body. Pitched directly against the Toyota Prius for UK commuters, company-car drivers and private-hire operators, the HEV and 8.9 kWh PHEV combine a 1.6-litre Kappa Atkinson-cycle petrol engine with an electric motor and a six-speed dry dual-clutch gearbox (6DCT), avoiding CVT engine flare while delivering 55–65 mpg in mixed British driving. A 2019 facelift brought a redesigned grille, a 10.25-inch widescreen infotainment system with Bluelink app control, steering-wheel regeneration paddles and an upgraded 38.3 kWh pack on the EV. Used examples wear high mileage remarkably well, though buyers must check for 12V auxiliary battery drain, hydraulic clutch actuator recall completion and low-speed 6DCT shudder.

Common Faults & Reliability
These are the most common documented problems for the Hyundai Ioniq (Hybrid/PHEV), sorted by their typical impact and frequency.
12V Battery Drain & Deep Sleep Bugs
medium severityThe auxiliary 12V battery can drain if the car is left for several days. On earlier models, this was often due to the car failing to enter a "deep sleep" mode, sometimes exacerbated by frequent Bluelink app pings or third-party tracking apps.
Clutch Actuator Fluid Leak
high severityAn internal leak in the hydraulic clutch actuator can lead to an electrical short and is a known fire risk. Most affected cars were recalled.
DCT Hesitation & Shudder
medium severityThe 6-speed DCT can feel hesitant or "shudder" when pulling away, particularly in cold weather or stop-start traffic.
