Hyundai Ioniq 5 vs Tesla Model Y: Reliability Compared
Hyundai Ioniq 5
Tesla Model Y
Reliability is effectively tied between the Tesla Model Y and Hyundai Ioniq 5. The Ioniq 5 keeps failing at one part, the ICCU. The Model Y spreads its problems across braking, steering and electrical faults, with far more recalls and crash-linked complaints.
How Do the Hyundai Ioniq 5 and Tesla Model Y Generations Compare?
Verdict
The Tesla Model Y is more reliable than the Hyundai Ioniq 5, scoring 55/100 vs 54/100.
Effectively tied. Neither car pulls ahead, because each has a different weak spot. The Model Y draws more complaints, more recalls, and crash-linked reports in every major problem area, with phantom braking and steering wear leading the list. The Ioniq 5 draws fewer complaints overall but more per car sold, and most trace to one failed part, the ICCU, which leaves the car in limp mode or stopped. Pick based on which failure you can live with: a spread of safety-related faults, or one repeat breakdown with long waits for parts.

What Are the Common Problems With the Hyundai Ioniq 5 and Tesla Model Y?
Owners describe two different problems. Model Y reports center on phantom braking at highway speed, sudden acceleration while parking, worn front suspension links and control arms, power steering assist loss, and screens that reboot. Every one of its main areas has crash-linked complaints, and steering has the most. Ioniq 5 reports mostly follow one chain: a pop, a "check electrical system" warning, a failed ICCU, then limp mode or a dead car. Crash links are few and mostly not tied to the ICCU. The fuel/propulsion area has none. Ioniq repairs stall on back-ordered parts, and failures recur after recall work.

Who Should Buy the Hyundai Ioniq 5 vs the Tesla Model Y?
Hyundai Ioniq 5 vs Tesla Model Y: Common Questions
- Is the Tesla Model Y more reliable than the Hyundai Ioniq 5?
- No, they are effectively tied. The Model Y has more complaints and recalls, plus crash-linked reports in every main problem area. The Ioniq 5 has more complaints per car sold, and many trace to one failed ICCU. Each has a clear weak spot, so neither wins outright.
- Which has more recalls, the Model Y or the Ioniq 5?
- The Model Y has far more. Federal recall records show 83 across its six model years, against 18 across the five model years of the Ioniq 5. Recall counts do not decide reliability alone, though, since the Ioniq 5 recall work did not always stop ICCU failures from returning.
- What is the ICCU problem on the Ioniq 5?
- The ICCU is the part dealers blame for the Ioniq 5's most common failure. Owners hear a pop, see a "check electrical system" warning, and the car drops into limp mode or stops. The 12V battery stops charging. Reports put failures around 22,000 to 25,000 miles, and repairs have taken a week or more.
- Is phantom braking common on the Model Y?
- Yes, it is one of the most reported issues. Owners say the car brakes hard on open highway with cruise control or Autopilot on, sometimes shedding 5 to 10 mph and forcing traffic to swerve. Some say software updates made it worse. Ioniq 5 owners report speed swings far less often.
- Which model years should I avoid on each car?
- Avoid the 2020 and 2021 Model Y and the 2022 and 2023 Ioniq 5, the weakest years for each. The 2024 is a safer target on both. The newest years, 2025 for the Model Y and 2026 for the Ioniq 5, look good but have had little time to collect complaints.
