Owners have filed 478 complaints
about the 2025 Hyundai Ioniq 5 with NHTSA between 2025 and 2026.
The largest single group is the electrical system.
Across this model's run it ranks 4 of 5 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 56
Against the median year of the Hyundai Ioniq 5. 50 means typical for this
model; 100 means roughly double.
Severity — 11
2.1% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — not reported
Too few complaints recorded a mileage to measure this.
How 2025 compares with every other Hyundai Ioniq 5
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2025 Hyundai Ioniq 5
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
United States — NHTSA

Recall 2025193440 units in Canada
Brakes
Issue: On certain vehicles, the software update completed by a Hyundai dealer for recall R0277 (Transport Canada recall no. 2025-054) may not be effective. As a result, a second repair is required. On certain vehicles, a software problem in the integrated electronic brake could cause reduced braking when using the left-foot braking (LFB) feature. Additionally, a software problem in the vehicle control unit could cause the vehicle to continue to accelerate for a short period of time when using the N e-Shift feature. Note: This recall replaces recall R0277 (Transport Canada recall no. 2025-054). This recall only affects certain Ioniq 5 N models. Safety Risk: Reduced braking can cause extended stopping distances and increase the risk of a crash. A vehicle that continues to accelerate could create the risk of a crash. Corrective Actions: To reduce the safety risk, Hyundai recommends not to use the LFB or N e-SHIFT features until the recall repairs have been completed. Hyundai will notify owners by mail and advise you to take your vehicle to a dealership to update the integrated electronic brake and vehicle control unit software.
Recall 2025054429 units in Canada
Brakes
This recall was replaced by Transport Canada recall no. 2025-193. Issue: On certain vehicles, a software problem in the integrated electronic brake could cause reduced braking when using the left-foot braking (LFB) feature. Note: This recall only affects certain Ioniq 5 N models. Safety Risk: Reduced braking can cause extended stopping distances and increase the risk of a crash. Corrective Actions: To reduce the safety risk, Hyundai recommends not to use the LFB feature until the recall repairs have been completed. Hyundai will notify owners by mail and send a wireless over-the-air software update to eligible vehicles to update the integrated electronic brake and vehicle control unit software. Alternatively, you may schedule an appointment to have the update performed at a Hyundai dealership. Note: Potential complications have been reported with the corrective actions and, as a result, the recall campaign is currently suspended. Hyundai is investigating the root cause and will provide an update once available. For owners who have already had the recall repairs completed, it is advised NOT TO USE the N e-SHIFT feature.
Recall 2024552824,695 units in Canada
Label
Issue: On certain vehicles, the compliance label may be missing information in French. The words listed on the label for "Tires", "Rims", "Front" and "Rear" appear in English only, when they should be listed as "Tires/Pneus", "Rims/Jantes", "Front/Avant" and "Rear/Arriere". Canadian regulations require this information to be listed on the label in both English and French. Safety Risk: These small errors do not affect vehicle safety. Corrective Actions: This is not a recall. The company has corrected the compliance label for all new vehicles.

POWER TRAIN
I was slowing down, actively pressing the brake pedal to bring the vehicle to a full stop. As the car decelerated to what my senses and perception registered as a full stop, I pressed the “P” (Park) button while keeping my foot on the brake pedal. I felt the physical click of the “P” button under my thumb while still holding the brake, and my mind registered that the vehicle had successfully transitioned into Park. Before turning around, I visually confirmed that the vehicle had come to a complete stop. Believing it was fully secured in Park, I turned my head to check on my child in the back seat and naturally released the brake pedal completely. However, the system had actually rejected my command. I assume that the vehicle likely still had a small amount of speed at the exact millisecond I pressed the button, and the computer automatically blocked the “Park” command and kept the car in gear. Because an electric vehicle operates in almost complete silence, with no engine noise or vibration to indicate that it is still in gear, there was no auditory or physical cue to alert me that the car was moving when I released the brake. While my attention was turned toward the back seat for a few seconds, the car quietly began to creep forward, leading directly to the collision with the car in front of me. Following the accident, I found that the vehicle produces slightly different sounds when Park is rejected and when it is successfully engaged. However, the owner’s manual describes only the dashboard message and does not describe these sounds or explain how to distinguish them, so their meanings may be learned only through the failure. At the time of the incident, I was not familiar with the distinction between these two sounds. Because my brain processed the physical press of the button as a successful action, and I had visually confirmed that we were not moving, my focus immediately shifted to my child. I was entirely misled by the digital interface.

STEERING
Driving at highway speeds, the front end feels unstable. It feels as if the tires are jumping around and will move the car to the right or left. It is difficult to maintain control. I had it into the dealer shortly after I bought the car to complain about what I thought was a front end alignment problem. They didn't think there was an issue until they got it into the shop. They said afterwords that it WAS OUT OF LINE. But their fix did not hold, so I went in again for the one year maintenace and mentioned the problem, but they said it was not out of line. Well, The problem still exists. Something serious is wrong and needs to be fixed.

On 8/30 my vehicle experienced a power loss on a highway (reported here separately). I took the car to the dealership and they could not replicate the error and gave the vehicle back to me on 9/4. Later that day I had to drive 2 hours north to a wedding in the mountains. At 9:30pm my vehicle experienced a full drive power loss on an unlighted, curving, rural 2-lane mountain road in an area with minimal cell phone service. I tried to restart the vehicle several times and could not get any power. I called roadside assistance and had to wait over 2 hours in the dark on a winding mountain road for the tow truck to find us and then be towed 40 minutes away to the nearest dealership where my car is still sitting waiting to be looked at (2 hours away from where I live)

VEHICLE SPEED CONTROL
Driving home near my apartment, I had to join a busy highway from a full stop. I found a small gap and tried to accelerate to quickly merge into traffic, when my car made a high pitched alert noise and noticably did not accelerate beyond about 25 miles per hour on a 45-50mph highway with heavy traffic. I turned on my hazards and still ended up with a line up of cars honking behind me. Flooring the accelerator did absolutely nothing to increase my speed. On slight downhills I could get up to about 40mph but as soon as it leveled off my speed went back down to limping along. I was able to exit the highway at slow speed and tried to parallel park in an avaialble spot but could not reverse. I tried to drive on toward my house but the car could not make it up the hill even with the full accelerator pedal down. People were stuck behind me on my street so I turned the car off and back on again and the car appeared to resume normal operation and I was able to drive up the hill. I took the car to the dealer and they were "not able to replicate the error". They did fix a seat belt recall and updated the software for my ECU and said to come back if it happened again...

While driving this EV with cruise control on, the dashboard suddenly showed a message that “Smart Cruise Control conditions not met”. Attempting to re-engage the cruise control did not work and then the vehicle suddenly lost all propulsion (pressing the accelerator did nothing). The car quickly slowed to about 20 mph before we could maneuver it to the shoulder and turn it off. After a couple minutes, we restarted the car and drove it to the dealer. There were no other messages or warning lights or indicators. The dealer could not find anything wrong and asked us to pick up the car and resume using it. We use both a home charger (Emporia) and roadside (Tesla) chargers.

My car starting throwing a “check electric vehicle system” warning intermittently beginning on July 7, 2026 which went away when I restarted the car. This happened again on July 27, 2026 three to four times while I was driving. The car did not lose power. As I was going to dealer the warning cleared and no code showed up in my diagnostic history. On August 12, 2026, the car once again showed "check electric vehicle system” and would initially clear when I restarted the car. I then began having intermittent power. Floored, the car would only go 27 mph. Then it would speed up again, then slow again. I was not in “turtle mode.” Luckily, I was able to safely get the car to the dealership without having an accident. DTC P1A8D13 did show in my diagnostics. The technician found that the 12v battery input had melted at the ICCU. This is very dangerous and could have led to a vehicle fire. My 2025 is on its 2nd ICCU (now 3rd) and has not had any recalls, so this is very troubling.

WHEELS
While driving on normal paved roads, a small vibration was heard from the rear of the vehicle. A person near the car when leaving the origin that morning heard a minor clicking sound at low speed from the rear of the vehicle. The vibration at that point seemed to be related to the rural mountain road that had some rutting. Continuing to drive, but onto better roads, the vibration became louder and louder, and appeared related to speed. Nothing appeared loose when stopping to charge. Vibration became loud (above conversation), stopped to inspect. Removed aerodynamic cover from lug nuts on right rear, and found two lugnuts completely sheared off (fell out when cover removed), with a third hanging on at less-than-finger tight. Vehicle driven slowly to safe location where it was towed to dealer. Dealer reported that the rim was bent in addition to sheared lug nuts as well as a damaged wheel bearing.

ICCU failure. Failure happened while merging onto the road from driveway. Upon failure, 12 V battery was drained and car was immobilized. Prior to car mobilization dash read “Check electrical vehicle system” then many different failures appeared on the dash, then the car shut down. This event left us stranded on the road, unable to move to a safer location. Issue was confirmed with dealer and part had to be replaced. Part was original to the car and issue is known by the manufacturer but not being dealt with publicly.

In June 2025, I started a lease on a new Hyundai Ioniq 5 SEL. On August 16, 2026, I attempted to start the car, but it immediately beeped and flashed a warning about the 12V battery (I didn't manage to take a picture). It then showed signs of an electrical issue, like flickering interior and exterior lights. It was undrivable. A short time later, there was no power at all. I took out the old 12V battery and measured the voltage with a multimeter, and observed 3.7V. After putting in a new battery, the car operated normally.

TIRES
Two tires failed dramatically, (on two separate days, but separated by only 121 miles of driving), causing extensive damage the first time and causing a total loss the second time. The first tire has been disposed of, but the second is available still. Each was on the highway and luckily there was not much traffic so I was able to pull safely onto the shoulder each time. However, if I had not been able to get over, our safety and that of others was at risk if we had been involved in a collision. My safety and my that of my elderly, handicapped brother was at risk the first time especially, because this is an EV and at one point on July 4, 100 degree temperatures in the early afternoon in South Carolina, the electrical system had been damaged and we could not, for a few minutes, get doors or windows open. The components (tires) have only been inspected by repair shops. There was no warning either time. The tires are 235/55 R 19.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
When I use the adaptive cruise control and use the lane keeping assistance the system keeps giving me an error message that I'm not looking at the road. I believe this is a known problem and Hyundai pushed an software fix TSB 25-G1-16H in November 2025. My car appears to have the update but still repeatedly gives me the same error message. It's very distracting and since the error message flashes on dash where you usually see the camera monitoring right side of car that feature is impaired. I have had at dealership twice and while the technician knows its an issue there's nothing they can do without Hyundai's decision to correctly fix with software update. I am over 6' tall and where glasses, two things I can't change.

I am over 6' tall and where glasses, two things I can't change.

LANE DEPARTURE: WARNING
When I use the adaptive cruise control and use the lane keeping assistance the system keeps giving me an error message that I'm not looking at the road. I believe this is a known problem and Hyundai pushed an software fix TSB 25-G1-16H in November 2025. My car appears to have the update but still repeatedly gives me the same error message.

UNKNOWN OR OTHER
My 2025 Hyundai Ioniq 5 experienced a complete and sudden loss of drive power at high speed, generating open fault code DTC P1A9096 (Internal ICCU Failure) [24V-204]. This failure completely matches the component and safety hazard profile under active Federal Safety Recalls 24V-204 and 24V-868 [24V-204].The vehicle was repaired at an authorized retail facility, Hyundai of El Cajon. The facility's un-finalized pre-invoice explicitly verified the ICCU failure code but deliberately omitted the federal safety recall context, routing the mechanical intervention under an internal manufacturer 'TSB 24-EV-004H' to hide the defect from consumer safety databases [24V-204].This represents a deceptive administrative effort to under-report active federal safety recall failures on newer model inventories across the E-GMP platform architecture [24V-204]. I am requesting a formal safety defect enforcement review into the manufacturer's regional reporting data.
