Rear-facing convert ible: The rear convert ible fit well in the Ioniq 5 thanks to its 39.4 inches of rear legroom. The Ioniq 5’s rear seats slide forward and back, and for our car-seat installations, we position the rear seat in its most rearward position. The car seat’s thinner, hooklike connectors made connecting to the Ioniq 5’s lower Latch anchors easy.
Forward-facing convert ible: Installing the forward convert ible also went smoothly. Connecting to the lower Latch anchors was a snap, and we raised the head restraint and used the sliding rear seats to gain easy access to the top tether anchors on the rear seatbacks. We slid the rear seat forward and connected the tether anchor without having to leave the backseat.
Booster: To get a better fit with our highback booster seat, we reclined the rear seatback and raised the head restraint to situate the booster’s back flush against the seat cushions. The outer seat belt buckles are on spring-loaded stable stalks. They sit a little low, but kids should be able to grasp them to buckle up independently.
B Grade
Latch: The Ioniq 5 has two sets of lower Latch anchors in the outer rear seats. The rear seats are well cushioned and the anchors sit just inside the rear seat bight, where the back and bottom seat cushions meet, making it a little challenging to connect to the Ioniq 5’s lower Latch anchors with bulky Latch connectors (like the infant seat’s). The EV has three sets of top tether anchors on the rear seatbacks that are well marked, making it easy for parents to find and use them.
Infant: We struggled to connect this car seat’s bulkier Latch connectors to the Ioniq 5’s lower Latch anchors; t took five attempts to finally make a connection on just one anchor. There was plenty of space for this rear-facing car seat. We didn’t need to adjust the front passenger seat to accommodate the infant seat.
C Grade
None
