When using the N-Shift mode with the current OTA software update, the car will accelerate when lifting off the throttle in higher gears at lower rpms in the programed faux shift logic.

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 the operator to do so. This unintended acceleration, given the performance characteristics of an electric vehicle with 640HP, could quickly place the vehicle and the operator in an unsafe and undesired situation that could result in a crash. I purchased this vehicle recently and have experienced the dangerous condition repeatedly, it is easily reproducible and appears to be an intended feature of the N e-Shift mode. The first time I performed a spirited acceleration in this mode the unintended acceleration put me in a undesirable situation that I was able to recover from with use of braking, however, I believe it is unsafe and will result in a crash if the vehicles are not recalled and a fix to the software is made to remove the dangerous component. My vehicle is available for inspection/reproduction of the issue. I have not brought it to the dealer or had an inspection done by any third party, given the nature of the issue being a software configuration, I don't expect any productive outcome other than a fix from the manufacturer. There are no warning lamps displayed. The issue has several confirmed posts and comments on social media: [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM
4 Reports24% of totalPreviewing the first 2 complaint summaries.
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 car for 12 days, the dealer stated it could not reproduce the problem and provided no service. This problem is identical to the problem that occurs on the regular Ioniq 5 and its sister model the Kia EV6 for which multiple safety recalls have been issued. Hyundai indicates that no recall has yet been made for the Ioniq 5N.

After recent software update on 17 March 2025, the vehicle demonstrated unpredictable high acceleration. Vehicle is unsafe in E-shift mode. Vehicle can only be driven safely in automatic mode. Per a Hyundai communication: "there have been complications reported related to the Vehicle Control Unit (VCU) software that may cause momentary continued acceleration during the release of the accelerator pedal while the vehicleâs N e-shift feature is engaged, increasing the risk of a crash. Our records indicate that your vehicle, VIN [XXX] , has had this software update installed as the remedy for recall 275. Hyundai is currently investigating the root cause of this complication and will provide an update when available. In the meantime, Hyundai recommends all owners who previously received remedy repair for recall 275 NOT TO USE the N e-SHIFT Feature."

While driving home, I experienced a sudden and complete power system failure in my Hyundai Ioniq 5 N. The failure occurred shortly after starting the drive, and was preceded by a faint "pop" sound. Within moments, the dashboard displayed the following critical warnings: Red 12V battery icon Red warning: "Stop vehicle and check power supply" Turtle icon (indicating limp mode / low power) Brake warning light â ï¸ The vehicle immediately entered limp mode, then fully lost power within approximately 3 minutes. I was able to safely pull into a nearby parking space before total shutdown and loss of power. Restarting the vehicle had no effect.
