Owner report 11633093 · 2024-12-30 (December 30, 2024)
The 12 volt battery (which is less than 6 months old) died on two separate occasions in the span of 4 days. Each incident required a call to emergency roadside assistance for a jump start. This is a safety issue. If the 12 volt battery dies while driving, the car will display a warning message instructing the driver to pull off the road immediately and shut off the car. The car will also lose power and cease operating shortly after this message appears. After the second incident, I took the car to my local Hyundai dealer but after having the c…

Owner report 11648940 · 2025-03-18 (March 18, 2025)
The Hyundai Ioniq 5N features a unique mode called N e-Shift which enables a software simulated 8-speed transmission that attempts to emulate the gear changes and driving dynamics of a traditional automatic transmission that would be found in an internal combustion engine vehicle. Unfortunately, the mode has a dangerous component in the programming, wherein, when the driver has been accelerating in a spirited fashion and lifts off the throttle, the vehicle CONTINUES TO ACCELERATE for approximately 1-2 seconds despite there being no input from …

Owner report 11716901 · 2026-02-10 (February 10, 2026)
Driving under normal conditions, heard a “pop” near the rear of the car and within seconds had an immediate loss of power. The dashboard had lit up with “Check electric vehicle system” and was limited to 20 MPH on a 45 MPH road with no safe place to stop. Was able to limp car home, dealer confirmed ICCU was faulty and had to be replaced. My family was very very lucky to not be on a highway when this occurred. Hyundai has continuously failed to not only fix the ICCU issues with this vehicle, but also hasn’t extended the warranty on the faulty co…
