Hyundai Ioniq I (AE) (2016 – 2019)

Reliability score : 8.9/10

The first-generation Hyundai Ioniq (code AE) is a landmark model: it is the first vehicle in the world to have been designed from the outset to offer three electrified powertrains (Hybrid, Plug-in Hybrid, and 100% Electric) on a single platform. Launched in 2016 to compete directly with the Toyota Prius, it stands out for its aerodynamic design (Cd of 0.24), its more conventional ergonomics compared to its Japanese rival, and the use of a dual-clutch gearbox (DCT) instead of a continuously variable transmission (e-CVT), offering a more natural driving experience. The hybrid version (HEV) is the core of the range, offering formidable efficiency and excellent overall reliability. A facelift (Phase 2) was introduced at the end of 2019, bringing technological updates and a larger battery for t

🎯 Verdict

The Hyundai Ioniq (2016-2019) is an exceptional choice on the used market. Data from the ADAC (1.8 breakdowns/1000) and TÜV (8.5% defect rate at 3 years) confirm reliability well above average. The Hybrid version (HEV) is particularly recommendable: it offers a smooth transition to electrification, negligible fuel consumption, and avoids the reliability issues of modern diesels (DPF, EGR). The DCT6 gearbox requires a slight adjustment at low speeds but proves to be robust. The electric version is a marvel of efficiency, but requires scrupulous verification of the recall history concerning the high-voltage battery.
