2020 Hyundai Ioniq
Here’s a breakdown of common issues and complaints for the 2020 Hyundai Ioniq, categorized and formatted as requested. The 2020 Hyundai Ioniq came in three main flavors: Hybrid, Plug-in Hybrid, and Electric. The Hybrid uses a 1.6-liter GDI four-cylinder engine paired with an electric motor, producing a combined 139 horsepower and 195 lb-ft of torque. The Plug-in Hybrid uses the same engine but with a larger battery pack for increased electric-only range. The Electric version features a 134 horsepower electric motor. Many owners appreciate the Ioniq’s fuel efficiency, comfortable ride, and generous standard features. Common dislikes include the somewhat bland styling, limited rear headroom (especially in the Hybrid), and the Electric version’s relatively short range compared to some competitors.
