AI Safety Analysis for the 2025 Hyundai Ioniq

The 2025 Hyundai Ioniq 5, despite being a relatively new model, exhibits a concerning safety trend primarily centered around its electrical system. With 261 total complaints to NHTSA, a significant portion, 110 complaints, are directly attributed to the 'ELECTRICAL SYSTEM'. Further compounding this, combinations like 'POWER TRAIN,ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM' (19 complaints) and 'POWER TRAIN,ELECTRICAL SYSTEM' (17 complaints) also point to electrical issues. The most critical and frequently cited problem is the failure of the Integrated Charging Control Unit (ICCU), which often manifests as a loud popping sound, followed by a sudden loss of drive power, reduced speed ('limp mode'), or complete vehicle shutdown. This has led to at least 2 reported crashes and 1 injury, highlighting the severe safety implications of unexpected power loss in traffic. While there are no recalls currently listed for the 2025 model year, several complaints explicitly mention that the ICCU issue has led to recalls for prior model years, suggesting a known design flaw that may extend to the 2025 model. The lack of official NHTSA safety ratings (Overall, Frontal, Side, Rollover are all N/A) means there's no independent crash test data to assess its performance in collisions. However, the prevalence of critical electrical failures that can disable the vehicle mid-drive raises significant concerns about its active safety and reliability. The overall safety picture for the 2025 Hyundai Ioniq 5 is currently concerning due to the high volume of critical electrical system complaints, particularly the ICCU failures. These failures pose a direct risk of stranding drivers or causing dangerous situations due to sudden power loss. The absence of official crash test ratings further limits a comprehensive safety assessment, but the documented real-world incidents of power loss are a major red flag for potential buyers.

Reliability Score

The 2025 Hyundai Ioniq receives a reliability score of 30 out of 100 based on analysis of NHTSA complaint data, recall history, crash reports, and safety ratings. This indicates below-average reliability. Significant issues have been reported by owners and should be carefully evaluated before purchase.

Known Issues for the 2025 Hyundai Ioniq

The following issues have been identified from NHTSA complaint data and owner reports for the 2025 Hyundai Ioniq:

IssueSeverityFrequencyTypical Mileage
Integrated Charging Control Unit (Iccu) Failure
The ICCU fails, often with a loud popping sound, leading to a complete loss of drive power, 'limp mode' (limited speed), or inability to start the vehicle. This can occur while driving, stranding the vehicle and its occupants.		 High Common 1700-6000 miles
Sudden Loss Of Motive Power
Vehicle unexpectedly loses power while driving, often at highway speeds, creating dangerous situations due to inability to maintain speed in traffic. This is frequently linked to ICCU failure.		 High Common unknown miles
Vehicle Unable To Start/Completely Dead
Car becomes completely unresponsive with no power, unable to start or even be put into park, often after being parked. This can be a symptom of ICCU or 12V battery issues.		 High Occasional unknown miles
