This 2022 Hyundai Elantra Hybrid poses an imminent fire and safety hazard due to catastrophic high-voltage system failures. On December 11, 2025 (Mileage: 54,527), the vehicle displayed a "Check Hybrid System" warning. The dealership diagnosed a swollen 12V battery and, critically, a melted power relay assembly and melted power cable. This indicates extreme thermal overload.

On March 23, 2024 (Mileage: 34,276), the vehicle suffered a total electrical blackout while driving at highway speeds at night. The vehicle lost all motive power, interior…

The 2022 Hyundai Elantra Hybrid Blue intermittently displays Check Hybrid System Stop Safety in instrument cluster screen, which stops the car from driving in either smart or normal. This happens on the roads and highways. This is very unsafe because at high speed when this happens you could easily get rear-ended because the car drops its speed and cannot accelerate any faster than 30 miles per hour and then it degrades to 20 miles per hour until I can find a safe place to park and turn off the car to do the reset to be able to drive again. This happens because the 12-volt lithium battery is not providing an acceptable amount of charge to the hybrid battery. This was also confirmed when I…
