Hyundai Ioniq I (AE) (2016 – 2019)

Reliability score : 9.2/10

The first-generation Hyundai Ioniq (AE), launched in 2016, is a pioneering model in automotive history: it is the first vehicle designed from the outset to accommodate three types of electrified powertrains (Hybrid, Plug-in Hybrid, and 100% Electric) within the same body style. This sheet focuses particularly on the 28 kWh Electric (BEV) version (produced until the facelift in late 2019, which introduced the 38.3 kWh). This version has become a cult favorite among electric vehicle connoisseurs for its exceptional energy efficiency (often under 12 kWh/100 km in real-world use) and its highly impressive fast-charging curve relative to its battery size. Overall, the Ioniq AE boasts a remarkable reliability record, supported by highly favorable statistics from the ADAC and the TÜV Report.

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The Hyundai Ioniq (2016-2019) is an absolute best buy on the used market, particularly in its 28 kWh Electric version. Although its battery capacity seems modest compared to current standards, its extraordinary efficiency and ability to maintain high charging power make it an extremely relevant vehicle for daily use and regional trips. Data from the ADAC (1.8 breakdowns/1000) and the TÜV Report (8.5% defect rate at 3 years) confirm reliability well above average. The Hybrid and PHEV versions are also excellent choices, offering a more conventional but equally rational alternative. The only real mechanical point of attention on the electric version concerns the reduction gear oil, a minor but crucial maintenance operation.
