Hyundai Elantra VI (AD) (2016 – 2020)

Reliability score : 7.8/10

The sixth-generation Hyundai Elantra (code AD) marks an evolution towards maturity for the Korean compact sedan. Abandoning the exuberant lines of the previous generation (MD) for a more sober and statutory European-inspired design, it benefits from a chassis made of 53% ultra-high-strength steel, significantly improving torsional rigidity and soundproofing. Globally recognized for its excellent price-to-equipment ratio and generous manufacturer warranty, the Elantra AD displays a reliability record ranging from "Average to Good" according to ADAC and J.D. Power. Important point: Unlike other models of the brand (Sonata, Santa Fe), the Elantra AD is not affected by the infamous recall of the Theta II engines. It remains a rational and economical alternative to the Japanese benchmarks, alth

✅ Strengths

Exceptional manufacturer warranty (often 5 years unlimited mileage in Europe, 10 years/100,000 miles on the powertrain in the USA)
Rigid chassis and secure road handling (especially the Sport version with independent rear suspension)
Intuitive interior ergonomics and responsive infotainment system
Absence of the Theta II engine (known to be problematic at Hyundai/Kia)
Soundproofing significantly improved compared to the previous generation

⚠️ Weaknesses

Critical piston ring defect on the 2.0L MPI (2019-2020 years)
Dual-clutch gearbox (DCT7) sometimes hesitant and generating jerks at low speeds
Quality of some interior plastics (lower parts) sensitive to scratches
Electric power steering (MDPS) lacking feel and prone to recalls (connectors)
Base versions (1.6 MPI) lacking dynamism

🎯 Verdict

The Hyundai Elantra VI (AD) is a rational, well-built, and generally reliable compact sedan that has managed to correct the eccentricities of the previous generation. Its main asset lies in the absence of the Theta II engine, which spares it the brand's worst problems. However, vigilance is required regarding the 2.0L engine from the 2019-2020 years, hit by a major recall concerning the piston rings. If you are targeting a model from these years, the service history is non-negotiable. The 1.6 MPI and 1.6 T-GDI (Sport) versions are the safest choices mechanically, provided you accept the sometimes rough character of the dual-clutch gearbox in the city.
