The Hyundai Ioniq Plug-In is still quite new, so it’s too early to say if reliability is on par with other Hyundai models. However, there’s a good warranty to rely on if things do go wrong.

Hyundai Ioniq Plug-In reliability & problems

With the Hybrid and Electric versions of the Ioniq launched in 2016 and the Plug-In arriving in 2017, it’s too soon to tell if reliability will be on par with other Hyundai models. Luckily, Hyundai does provide a competitive warranty, lasting for five years and with unlimited mileage, so any issues should be taken care of. In addition, there’s an eight-year warranty for the battery.

Hyundai is facing challenges, however, with a 15th-place finish for the brand out of 26 manufactures in our 2018 Driver Power customer satisfaction survey. That’s a worse performance than in previous years, so the firm really needs to up its game.


There should be no such worries regarding safety, with the Ioniq posting impressive Euro NCAP crash-test results. Despite the tests getting more stringent in recent years, the Ioniq easily obtained the full five stars, with an impressive 91% for adult occupant protection and 80% for child occupant protection.

Just as impressive is the 82% in the safety assistance category, which takes into account the included safety technology. Seven airbags are fitted.

The entry-level Premium trim gets autonomous emergency braking as standard, which performed faultlessly in Euro NCAP’s tests. This system is also designed to detect pedestrians, as well as other cars. Other standard safety kit across the range includes lane-keeping assistance and lane-departure warning to help avoid drifting towards other traffic on the motorway.

A reversing camera also helps avoid parking bumps, while smart adaptive cruise control uses radar technology to maintain a set distance from the car in front on motorways. Premium SE trim adds blind-spot monitoring, rear cross-traffic alerts and front parking sensors.
