Yes, by a large gap. The Sportage draws 5.3 owner complaints per 10,000 sold, against 63.4 for the Ioniq 5. Ioniq 5 complaints cluster around ICCU failures that cut power or kill the car. Sportage complaints are fewer and spread across engine, electrical and brake problems.

Which has more recalls, the Sportage or the Ioniq 5?

The Sportage has more, with 28 recalls across 9 model years. The Ioniq 5 has 18 across 5 model years. The Sportage has been sold for more years, so its total has had longer to build. Recall counts alone do not make it the less reliable car.

What is the biggest problem with the Hyundai Ioniq 5?

The ICCU. Owners describe a pop, a "check electrical system" warning, then a power-limited mode that often ends with the car stopping, sometimes at highway speed. The 12V battery stops charging. Failures appear around 22,000 to 25,000 miles and can return after recall work, with repairs delayed by back-ordered parts.

What goes wrong most often on the KIA Sportage?

Engine problems lead, with 151 complaints. Owners report oil running out between changes, then knocking or lock-up, usually ending in engine replacement. Electrical faults come next, including stalling and a touchscreen that goes black. Some owners also report cruise control setting itself to 110 mph.

Which Sportage and Ioniq 5 years should I avoid?

For the Sportage, be careful with 2018 and 2023, the weakest years. For the Ioniq 5, avoid 2022 and 2023, which rank weakest. The 2024 Ioniq 5 ranks stronger. The newest years of both look good partly because they have had less time to collect complaints.

Hyundai Ioniq 5 vs Kia Sportage: Reliability Compared

Hyundai Ioniq 5

Mixed

More Reliable

Kia Sportage

Good

Reliability favors the KIA Sportage over the Hyundai Ioniq 5 by a wide margin. ICCU failures drive the Ioniq 5's much higher complaint rate, while Sportage problems are scattered and rarer.

How Do the Hyundai Ioniq 5 and Kia Sportage Generations Compare?

Two different positions in the cycle matter here. The Sportage data runs through the fourth generation (QL, 2017 to 2022, facelift in 2020) and into the fifth generation (NQ5), which began with the 2023 model year. That makes 2023 a weak year and the first of a new design, while 2018 is also weak and sits early in the fourth generation. The Ioniq 5 has had one generation (NE) since 2022, with a facelift for 2024. Its 2022 and 2023 cars are the pre-facelift ones and rank weakest. The 2024 facelift year ranks stronger, so it is a safer starting point for a used shopper.

Verdict

The Kia Sportage is more reliable than the Hyundai Ioniq 5, scoring 75/100 vs 54/100.

Reliability favors the Sportage, and the gap is large. Ioniq 5 complaints run at a far higher rate, and most describe one failure: an ICCU that quits and leaves the car in a power-limited crawl or dead. The Sportage has serious problems of its own, including engine failures, but they spread across several systems and show up much less often. Federal recall records list more recalls for the Sportage, though it has been sold across more model years.

What Are the Common Problems With the Hyundai Ioniq 5 and Kia Sportage?

A single failed part dominates the Ioniq 5's record. A loud pop, a "check electrical system" warning, then turtle mode or a dead car points to the ICCU, sometimes at highway speed and sometimes again after recall work. The Sportage's trouble is scattered: engines that run low on oil and lock up, cruise control that sets itself to 110 mph, early warped front rotors, and phantom automatic braking. Among the listed problem areas, the Sportage has crash links in service brakes and engine, which the Ioniq 5 list lacks. The Ioniq 5 has crash links in forward collision avoidance, which the Sportage list lacks.

Who Should Buy the Hyundai Ioniq 5 vs the Kia Sportage?

Choose the Sportage if you want the lower chance of a long stay at the shop. Its owner complaint rate is a small fraction of the Ioniq 5's. Be cautious with 2018 and 2023, which are among the weakest years. The newest years look strong, but they have had little time to collect complaints. Keep your oil changes documented, because owners report Kia denying engine claims over maintenance records. On a test drive, check the cruise control and the brakes. Choose the Ioniq 5 only if you want an electric SUV and can live with the ICCU risk. Failures were reported around 22,000 to 25,000 miles, and repairs have dragged on for a week or more because parts were back ordered. Avoid 2022 and 2023, the weakest years. The 2024 year ranks among the stronger ones and is also the facelift year. Ask for ICCU repair history, and check that the 12V battery holds a charge.
