2018 Hyundai Ioniq plug-in hybrid problems
The Hyundai Ioniq is a compact five-door liftback manufactured and marketed by Hyundai. The nameplate Ioniq is a portmanteau of ion and unique. It is marketed as the first Hyundai automobile to be offered without a standard internal combustion engine, but rather sold in hybrid, plug-in hybrid, and all-electric variants.
The Ioniq Hybrid debuted in South Korea in January 2016, with all three variants debuting at 2016 Geneva and New York auto shows. The hybrid variant launched in its home market in February 2016, followed by the electric model in July 2016. The plug-in hybrid version followed in February 2017.
From its first model year (2017) through the 2019 model year, the Ioniq Electric had been the EPA's most efficient vehicle with a rated fuel economy of 136 miles per gallon gasoline equivalent (24.8 kWh/100 mi; 15.4 kWh/100 km). The Ioniq Blue Hybrid version has been rated at 4.1 L/100 km (58 mpg‑US), making it the most fuel-efficient hybrid vehicle to be mass-produced.
Following its discontinuation in South Korea in 2021, production of the Ioniq ended in July 2022 in favour of battery electric lineup of Ioniq-badged models starting from the Ioniq 5 hatchback and Ioniq 6 sedan with Ioniq 7 to follow.
