vehicle battery failure
Integrated Charging Control Unit (ICCU) failed while driving. Heard a pop from below the rear seats. "Check vehicle electrical system" message popped up initially, then changed to "Stop vehicle and check power supply" Vehicle could not exceed 20mph directly after failure, then lost all driving power just as I pulled the vehicle off the road. If I hadn't found a place to pull over in time, the car would have stopped in the middle of the road putting my safety and the safety of others at risk. Dealer inspected and took over a month to replace ICCU and 12v battery.
Car's ICCU blew as I was pulling out of my driveway. Was able to limp to the dealer. They replaced the ICCU in a week.
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 component here in the US like they’ve done in Asian markets. As a consumer, I’m begging the NHTSA to hold Hyundai accountable for these ongoing EV issues.
I have experienced two high voltage battery failures both requiring hv battery replacement. The first occurred around 6000 miles and the second occurred around 13,000 miles. I also had several dead 12v battery episodes where the card would be dead; even when plugged into the home charger overnight. I had to replace the 12v battery at 12000 miles.
ICCU failure and fuse, the car became unoperational and needed to stop. The car would no longer charge the 12V battery, and the EV battery would not charge. Hybrid Control Problem Detected at 3,160 miles. DTC P056216

What happened to me is a common problem with these models. I had an issue with the 12 V battery not being charged by the main battery as it should be. This led to a blowing of the main fuse which took out the ICCU unit. This seems to be fairly prevalent from what I can tell from online forums, and there needs to be a recall from Hyundai.
The contact owns a 2025 Hyundai Ioniq 5 N. The contact stated that while driving at 40 MPH, the service battery immediate warning light illuminated. A dealer was contacted. The vehicle was taken to the dealer because the ICCU unit needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 8,000.
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 ️ 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.
The contact owns a 2025 Hyundai Ioniq 5 N. The contact stated that while driving and exceeding 30 MPH on several occasions, the accelerator pedal was released; however, the vehicle accelerated unintendedly for three seconds. Additionally, the contact stated that upon depressing the brake pedal, the vehicle responded as intended after three seconds. The vehicle was taken to an unknown dealer, where it was diagnosed and determined that the ABS module had failed, and a software update was needed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 9,200.
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 vehicle’s 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." INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The dealership performed the software update from the Hyundai recall 275. After the update, when using the e-shift feature in N mode the car sometimes will accelerate out of control on its own without the accelerator pedal being engaged. Hyundai also changed the motor sounds and e-shift feel.
With Eshift enabled, the car continues accelerating under heavy throttle even after releasing the accelerator pedal.
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)
After the recent RECALL, while driving up I almost got in an accident because after upshifting the car, the car accelerated more than I intended, prolonged movement forward that never happened before the recall. This is a very dangerous situation.
When accelerating using the N e-shift mode and letting off the accelerator the car continues to accelerate.
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 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.

The basics
How to read this data
Complaints, recalls, investigations — here’s what each number actually tells you about a used Hyundai Ioniq 5 N, in plain English.
What is an NHTSA Complaint?
An NHTSA safety complaint is a report filed directly by a vehicle owner or driver describing a safety-related issue. Anyone can submit a complaint at NHTSA.gov. The number of complaints is a signal of how common a problem is — but complaints per model-year matter more than raw totals, since popular vehicles naturally receive more reports. The Hyundai Ioniq 5 N has 18 complaints on record across 2 model years.
What is a Safety Recall?
A safety recall is a mandatory campaign issued by NHTSA when a vehicle component poses an unreasonable risk to safety or does not comply with federal motor vehicle safety standards. Unlike complaints (which are owner-reported), recalls are formally investigated and confirmed by regulators. Manufacturers must fix recalled vehicles free of charge. The Hyundai Ioniq 5 N has 0 recall campaigns in the NHTSA database.
What Are Crash Complaints?
Crash complaints are NHTSA filings where the owner indicates a crash occurred as part of the incident. 0 of the Hyundai Ioniq 5 N's 18 complaints involved a crash. This metric is particularly important because it indicates how often defects resulted in actual collisions — a key safety signal beyond general reliability.
How Is the Reliability Verdict Calculated?
The reliability verdict (Good) is generated by analyzing the vehicle's total complaints, recall history, crash complaint ratio, fire complaint ratio, and top component failures relative to class averages. This verdict gives buyers a quick interpretation before they review year-level details and VIN-level history. It should be treated as one decision input, not a substitute for a VIN-specific report.
Why Do Newer Years Have Fewer Complaints?
Newer model years appear to have fewer complaints because there has been less time for owners to file them. Complaints accumulate over years of ownership. A 2020 model year vehicle will typically show fewer complaints than a 2015 model year even if it is less reliable — simply because fewer owners have had time to report issues. Focus on complaints per year of market presence when comparing across model years.
Fleet Data vs. Individual VIN
Everything on this page reflects aggregated data across all Hyundai Ioniq 5 N vehicles on the road — not any specific car. Two Hyundai Ioniq 5 N vehicles of the same year can have very different histories: one may have been in three accidents and have an open recall; another may be clean. A VIN check gives you the individual car's history: accidents, title brands, odometer records, service history, and real-time recall status.
What Are NHTSA Investigations?
When NHTSA receives a pattern of related safety complaints, it opens a formal investigation. A Preliminary Evaluation (PE) is the first stage — NHTSA determines if a safety defect may exist. If evidence is strong, it escalates to an Engineering Analysis (EA), which can result in a mandatory recall. The Hyundai Ioniq 5 N has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
