Back in 2018, Hyundai recalled some 10,000 2017 and 2018 Ioniqs (754 vehicles in Canada) due to a possible increased electrical resistance caused by a loose connection between the main relay and power relay assembly located under the rear seat. The company switched suppliers and repaired the recalled Ioniqs.
We apologize, but this video has failed to load.
However, Hyundai is recalling those same vehicles — the 2017 and 2018 Hyundai Ioniq Hybrid and Plug-in Hybrid models — again due to the exact same issue. It appears the initial defective part was replaced with yet another defective part, meaning all 10,575 units that were previously recalled are being recalled for a second time.
Though Hyundai has not reported any injuries or accidents related to this issue, the loose connection can cause heat buildup that can lead to a warning light coming, or potentially a fire.

How It Works: Vehicle recall notices
According to the National Highway Traffic Safety Administration (NHTSA), Hyundai will begin notifying owners in late August. Dealers will inspect and replace necessary parts, free of charge. Note that vehicles already repaired in the previous recall should still be inspected to have the new fix completed.
Update: According to Hyundai Canada, this Ioniq recall will not affect Canada at all.
