What should I look for in a used Hyundai Ioniq saloon?
When viewing a used car, always follow our used car buying checklist.
Check the bodywork for scuffs picked up in city centre car parks and look at the operation of all the seats. Some of the plastics in the interior can show marks if it has had a hard life. Make sure all the electrical features work, because there's plenty of them. However, all Ioniqs at the moment will still be covered by the five-year manufacturer's warranty, so defects shouldn’t be a major issue.
What are the most common problems with a used Hyundai Ioniq saloon?
Coolant leak: There has been a recall for early Ioniqs built between 4 October 2016 and 31 March 2017 related to coolant that might leak into the electric power control unit. Contact your local Hyundai dealer if you think your car might be affected by this.
Risk of power relay fire: There's a possibility that some examples may suffer from a faulty power relay that could, in extreme circumstances, catch fire. Hyundai dealers are to replace the power relay and inspect the power cable and relay assembly for any damage and replace if necessary.

Is a used Hyundai Ioniq saloon reliable?
The Hyundai Ioniq hybrid and plug-in hybrid are both reliable, but the electric version isn't, as shown in our latest What Car? Reliability Survey.
Starting with the former two, they ranked fifth out of 29 cars in the family car class. Its reliability score of 96.5% puts it above many rivals, like the Ford Focus and Toyota Corolla.
A mere 3% of examples reported on for our survey had any problems. Bodywork and the sat-nav/infotainment system were the only areas of concern, with all issues dealt with swiftly at no cost to owners. All cars remained driveable, and remedial work took a day or less, with Hyundai and its dealers covering the cost of all work required to sort things out.
The electric model, on the other hand, came 14th out of 18 cars in the electric car class. Its score of 86.5% means rivals like the Tesla Model 3 and VW ID 3 are more reliable.
The 12-volt battery was the biggest headache, followed by motor and non-motor electrics. Although all repairs were done for free, 60% of faulty cars were stuck in a workshop for more than a week.
As a car brand, Hyundai managed a good 10th place finish out of 31 manufacturers. Its overall reliability rating of 93.5% makes it more reliable than Kia but less reliable than Toyota.
