VISIBILITY/WIPER
When driving down the road, road debris and water blind the back windshield. There is no wiper and the design does not clear off the back windshield, causing you not to be able to see out the back windshield. This is causing a safety issue with the vehicle, and I almost had an accident because of it. Additionally, the side mirrors will not clear off water, causing them not to be able to use during rain storms. This vehicle is not safe as is. Hyundai has stated it is a design defect and they won’t do anything about it, per the corp office and the dealership, Jenkins Hyundai in Ocala, Fl

FUEL/PROPULSION SYSTEM, ENGINE
When in motion, the “EV Start Stop”button is still allowed to turn off the vehicle if accidentally pressed. This happened to me while on the highway and moving about 15-20 MPH. The vehicle suddenly lose power and wouldn’t accelerate. I could not move the vehicle, without hitting the EV Start Stop button several times.

Hyundai San Jose dealership, Customer Service, told me, The fuse surrounding the Lithium battery is broken. This causes the whole car break down, and it is very dangerous to drive. My car has been in this Hyundai dealership over 5 months now, Hyundai cannot send the parts to San Jose Hyundai and I cannot drive the car. Also the 12V small lead acid battery in the front, broken down a few times. Cannot start the car. The whole car shuts down.

SERVICE BRAKES, ELECTRICAL SYSTEM
When driving in I Pedal mode (which is the one-pedal mode), the brake lights do not light up when decelerating, and it almost caused us to be rear-ended yesterday. Drivers pull aside me and tell me my brake lights don't properly come on when I slow down. Apparently this defect was on the national news several months ago and Hyundai promised a software fix by mid-July. I was just at the Carlsbad, CA Hyundai Service Center this morning and was told they do not have a software fix for this issue. This car should officially be recalled by Hyundai and the NHTSA and owners should be warned officially they are driving a dangerous, defective car.

POWER TRAIN
After owning and driving the 2023 Ioniq 5 for about 4 months, the car was driven from Massachusetts to Arizona. After driving across the county at 75 mph about 50 min on cruse control the car began to lurch, the speed would drop about 3 mph below the cruse control set point, then accelerate to a mile faster than the set point and then settle down to the set point. This would happen multiple times during the next 100 miles before stopping to charge. After charging and again on cruse control at 75 mph or so, the lurching would begin again. After the lurching started, the power display indicated the front motor on this dual motor vehicle was doing all the work to drive the car, and the rear motor was no longer functioning. Later it was confirmed that the rear EOP (electric oil pump) which cools the rear motor was not functioning at all. As a result the rear motor would increase to more than 170 degrees F and stop operating. No DTC was stored for the EOP Actual Speed of zero (despite an EOP Command Speed for 800-3000 rpms). No DTC was stored for the MCU Motor Temperature overheat. No DTC was stored for the MCU Motor Actual Torque of zero when it was commanded for something more. Fortunately the Hyundai Ioniq 5 did command the front motor to take over even though the rear motor was no longer functional, so the car was able to maintain speed most of the time. However, the car is normally 325 hp with both motors. Accelerating with only the 95hp front motor on a heavy car was very slow, both in traffic and on the highway. The lack of performance could easily surprise an unsuspecting driver resulting in a collision or worse. I know of at least 5 owners who have experienced this issue. In each case Hyundai has been slow at best and refused to repair at worst. The issue is without DTC but can none the less be easily diagnosed by observing the ODB EOP Actual Speed (when the car is driven) will be zero with an EOP Command Speed >0 .

ELECTRICAL SYSTEM
My car fails to charge using Level 2 40 amp charger. The car is supposed to be able to maintain charging between 40 and 48 amps. It is clear that the car is overheating during Level 2 charging and suspending charging. This can be dangerous especially if the car is advertised to be able to charge normally using Level 2 chargers. Note that the summer has been hot. Even in my garage at night, I can no longer charge at 40 amps. I have to lower my Autel charger's current down from 40 amps to 32 amps, and that seems to work. Outdoors during the day, I have to change the car's current to 60%, just so it can continue to charge without overheating. My car is less than 6 months old.

ELECTRICAL SYSTEM
Charge port is overheating and stopping charging. Widespread issue after the cars age. Their only fix is a software update that drastically throttles current to the car. Rendering very long charging times compared to what was advertised. Something is deteriorating in the electrical system since the cars charge fine when new. Overheated electrical components is very concerning. I hope NHTSA makes Hyundai remedy this issue!

VISIBILITY/WIPER, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: BLIND SPOT DETECTION
This car has detailed complaints online for the absence of a rear wiper causing zero visibility during afternoon rain and thunderstorms. In the event of a white out situation, the driver assistance systems fail to work due to hazardous conditions. You also cannot see out of the rear window or side mirrors because of a design defect. The car has been reported to Jenkins Hyundai of Ocala, where the service department is aware and informed me that Hyundai is aware of the safety concerns, but cannot fix the situation or will not offer a fix to the serious safety concern. The service department gave me the phone number to report this as a lemon to Hyundai Customer care where I was informed twice a manager named [XXX] has my case and would contact me, which she has not done. The case number given is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving and the car suddenly slowed down unable to accelerate much and showed a messaged saying 'Check Electrical Vehicle System‘. The service center says it is an ICCU problem. I have been waiting several weeks the part is still on backorder without any ETA.

FUEL/PROPULSION SYSTEM
When starting the vehicle I received an error that said "Check Electric Vehicle System". The vehicle seemed to be working fine at slow speeds in the parking lot at work. When I exited onto a city street I realized I had lost normal acceleration and could not go above 25mph. I pulled into a parking lot and turned the car off and on to see if the error cleared. It did not. Also received an additional error stating " Stop vehicle and check power supply". At that point I called roadside assistance for a tow. The vehicle is now at my local Hyundai dealership. Their service dept has stated they will take a look at it in 7-10 days most likely.

FUEL/PROPULSION SYSTEM
Recently - my car has been encountering an issue and it has been slowly getting worse and worse. I have a 40 amp Level 2 charger I frequently use to charge my car. I first noticed it a few weeks ago, where my car seemingly stopped charging for no reason. I brushed it off, then unplugged it + plugged it back in and the rest of the session went fine. Lately, as temps have been rising I noticed the car failing charging sessions one, or two times per day. After doing some research, it turns out i’m far from the only one having this issue. Many other others have been experiencing the same issue as I, and the same degradation. Some people who were initially able to charge their car at 11kw, are now only to charge around 5kw, otherwise the cars onboard AC charger gets too hot and ends the charging session. I have started to see my car degrade as well, as I have had to lower my charge rate to 32a. I have tested out Level 2 AC charging on other chargers as well to rule out my charger being the problem, and it happens on them too unfortunately. To combat this AC charger overheating issue, Hyundai has released a TSB number 23-EV-003H. Unfortunately, the only thing this TSB does is kneecap the cars ability to level 2 charge at a decent rate. After the TSB is applied, once the car detects an overheating onboard AC charger, it will throttle the AC charge rate all the way down to around 5kw. This is unacceptable, when owners of the Ioniq 5 and 6 were promised a vehicle that is able to do 11kw AC charging, or as claimed on Hyundais website, a Level 2 charge from 10-100 in 6 hours and 43 minutes. With my car throttled to 32 amps, it doesn’t charge nearly as fast adding hours onto the total time required to charge. This is an issue for me because I do not have a place to come home to every single night to charge my car, i’m only able to stop by the charger momentarily which means securing as much energy as fast as possible through Level 2 charging is very important to me.

Car intermittently stops charging using a level two charger. Problem started approximately February 2023. Did not happen prior to that date. Car will issue a report through blue link app every 2 to 3 minutes reporting charging failure. This alert will happen approximately 50 times throughout the charging process until charging is complete.

TRAILER HITCHES
The Draw-tite 76589 was purchased through Uhaul Canada for my 2022 Ioniq5. After a few months of use with a light trailer according to the specifications of Hyundai, Uhaul and Drawtite, it tore of a part of the vehicles frame. After the inspection at U-Haul and Hyundai dealership, they concluded that the problem occured because the hitch wasn't designed to mount on the specified by Hyundai mounting spot, hence it caused the damage. There are many cases like that on Ioniq5 forum as well as at different hitch installing companies who used this model. This model is now discontinued, although still sold, and was replaced by a 76632 model which mounts to the right location. Horizon Global did not contact the customers, not their distributors/dealers and doesn't compensate the customers who contacted them. After 7 months I still have the hitch on the car if you want to inspect it.

ELECTRICAL SYSTEM
While driving in heavy rain, I got warning: Stop and Check Battery. When I could find a safe place I stopped and read the Manual. I could find nothing helpful. My car was 63% charged. This was the 12v battery failing. I was then 5 miles from home. I turned off radio and lights, but could not drive without wipers. At about 2 miles from home the car slowed down. I continued to lose power as the rain got heavier. I was able to keep barely moving until I pulled into my driveway. I got out and locked the car by habit. I realized I needed it unlocked, but it was too late; it was DEAD. At the end the display read Losing Power and showed a small turtle. Indeed.

I have a 2023 Ioniq 5 that was purchased in June, 2023 and an 2023 Ioniq 6 that was purchased in April, 2023. I had a new Chargepoint Home Flex charger installed in April when I purchased my Ioniq 6 and set the charging current to 40 amps. The charger was hardwired directly to my service panel with the appropriate 6 gauge wire and 60 amp breaker. My Ioniq 6 reliably charged at 40 amps until early July when it started dropping the charge rate to 23 amps about 40 minutes into my charging session when using the level 2 charger at home. My Ioniq 5 only charged at 40 amps for the first week of ownership before starting to drop the charge rate to 23 amps. When this behavior started I plugged an OBD2 scanner in and was able to monitor the AC Charging Inlet temperature and noticed that the charge drop happened when the temperature reached 240F. This causes an issue when planning my charge times because they can essentially double, meaning that my vehicles are not ready for a trip by the estimated time. I am also concerned that having electronics that overheat on an EV may be a potential fire hazard in the future. One of the key reasons for purchasing these vehicles was the advertised charge times. I have appointments with the dealership to have both vehicles examined.

The car (2022 Ioniq 5, an EV) lost power while driving. There was warning at the same time stating that the car is losing power and need to stop for safety. Minutes later the car completely lost power and can not be turned on. The car has to be towed to Hyundai dealer. It has been 2 months and 2 weeks and the car is till in Hyundai dealer's lot without being repaired. We were told by the dealer a control unit need to be replaced and it has to be shipped from Korean.
