Electric Motor

Electric Motor

• Reduced Power/Turtle Mode
  • Description/Symptoms: Some owners have reported instances where the Nexo enters “turtle mode” or experiences significantly reduced power output, even with a sufficient hydrogen fuel level. This can occur under various driving conditions and is often accompanied by warning lights on the dashboard.
  • Solution: This issue often requires a diagnostic check by a certified Hyundai technician. The issue could stem from multiple parts. Often the issue is related to the high-voltage system, and a software update or component replacement may be necessary.
  • Estimated Cost to Fix: Diagnostic fee: $100-200. Repair cost depends on the faulty part.
  • Recalls: None Found

High Voltage Battery

• High Voltage Battery Failure
  • Description/Symptoms: A small number of owners have reported the high-voltage battery failing completely or exhibiting significantly reduced capacity. This can result in the vehicle being unable to start or having a drastically reduced driving range.
  • Solution: Replacement of the high-voltage battery pack is the only solution.
  • Estimated Cost to Fix: $15,000+ (including labor). Battery replacements are generally covered by Hyundai’s warranty, but out-of-warranty repairs are expensive.

Summary

The 2021 Hyundai Nexo, while innovative and environmentally friendly, does experience some issues. The most concerning are related to the high-voltage battery and motor, which can be costly to repair if not covered by warranty. Electrical glitches and suspension noises are also common complaints. While the frequency of these issues seems relatively low, potential buyers should be aware of these possibilities and ensure they have access to a reliable Hyundai service center experienced with fuel-cell vehicles. The overall severity of the issues ranges from minor annoyances to potentially significant repair expenses.
