- #11571586February 13, 2024FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The contact owns a 2023 Hyundai Ioniq 5. The contact stated that while driving at an undisclosed speed, a Jeep veered into the driver’s path, and the Forward Collision Avoidance: Automatic Emergency Braking system failed to activate as designed. There were no warning lights illuminated. The vehicle was taken to the local dealer, who determined the vehicle was working as designed. The vehicle was not diagnosed or repaired. The vehicle was taken to another local dealer, Feldman Hyundai of New Hudson (30492 Lyon Center Dr., New Hudson, MI 48165), who stated the vehicle was working as intended. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 15,000.

I heard a pop from the rear of the car and warnings came up on the dash. The vehicle was power limited and needed to be towed to the dealer. It was diagnosed as an ICCU failure and blown fuse. This was the problem supposedly addressed in Hyundai TSB 997 (NHTSA ID Number: 10240086). That service was performed on the vehicle in September 2023. We were lucky the incident occurred on a city street and not on a freeway or rural highway where the sudden loss of power could have been very dangerous. The software fix applied under Hyundai’s TSB clearly did not fix the issue.

12/30/2023 at approximately 5:30pm I drove home with the iPedal engaged. The iPedal was installed as a download to the car in August 2023. My daughter was in the passenger seat. I began to back into my driveway but shifted to Drive to straighten out the car. The car began to roll forward I took my foot off the accelerator but the car did not stop in spite of the iPedal being engaged. I put my foot on the BRAKE PEDAL which went all the way to the floor to no avail. The car rolled slowly into an electrical pole which brought the car to a stop. Neither iPedal nor the foot brake pedal had any effect on the car. I then put the car in reverse and backed the car into my driveway and the brakes worked as expected. When I then attempted to charge the vehicle, the charging port would not open. I could hear the motor working to open but it would not open. On 1/11/2024, I again attempted to open the charging port and this time it did open. So, TWO different electrical (including the brakes and the charging port) were not working properly. Inasmuch as the charging port again worked and the brakes again worked, there clearly was a malfunction that was random and unpredictable and also nearly impossible to reproduce but if this happened once, it could happen again. The brakes failed. Had we been traveling on a busy road, or at the top of a hill, we would have faced significant bodily harm, death to ourselves or others. This car had been driven locally, predominantly on local roads. The car is available for inspection and has only been driven on the dealer lot since the the incident. There were no warning lights or messages to indicate that any issues existed. The manufacturer has executed an inspected but has not reproduced the problem. The manufacturer and dealership claims the car is safe to drive without addressing the brake failure. I do not believe the car is safe to drive without a determination of how the bake failure happened or without a repair to that issue.

Driver was moving forward into a space in a parking garage between two other vehicles. Driver had pulled most of the way in and was slowly inching forward. As the car came to a stop, it suddenly lurched forward, hitting a concrete wall. The collision warning system did not alert, and auto-braking did not occur. The car was in Regen Level 3, and Auto Hold was not activated. In the months prior to this, the car twice had a similar situation when coming to a stop at an intersection with foot on the brake, then suddenly lurched forward, nearly rear-ending a car in front. There was no visible damage to the concrete wall, and a police report was not made. Hyundai says they want to inspect vehicle, but have not done so after a month. It is easy to believe that this was driver error, but it absolutely was not. Car lunged forward and accelerated into a wall with only the brake being applied. All of these events have occurred after the Hyundai Ioniq 5 software update was applied on 26 Sep 2023.

Driving the vehicle on the highway for longer than 60 miles at highway speeds the vehicle goes into “power limited” mode and a turtle pops up on the screen. You are unable to accelerate the car and once this happens you have to leave the car off for at least 5 minutes and then not drive above 65mph again or it will keep happening over and over. After taking it to the shop Hyundai Corporate said we need to drive the car again to see if they had fixed it. Approximately 65 miles into the trip it happened again and this time I was almost rear ended and cars were swerving around me on the shoulder to avoid crashing into me. Hyundai is saying that they cannot reproduce the issue but they are not driving the car on the highway for more than 60 miles. The safety of not only myself and my family is at risk as well as other people on the highway behind and next to us. The vehicle is currently at the dealership and they said there are no error codes so they don’t know what’s wrong. The only warning that popped up said “power limited” with a turtle.

I was waiting to charge up my EV when the dashboard started lighting up red. Stating to turn off vehicle due to battery failure and safety. And then all of the sudden the car just turned off. And would not come back on. So my husband had to go rent a vehicle at Avis so we wouldn’t be stranded so far from home. And to continue to go to work. So after 30 minutes my husband suggested that I try and restart the car and it did come on. We were stuck in the freezing elements due to the battery failure. Which seems to be an issue that they had back in 2022. That wasn’t correct or thought to have been. After I did some research yesterday 1/24/24. I called and made the local dealership aware of what I discovered that I took my car to. Because they couldn’t see if they would get same issue but they stated they didn’t.Also called into road side assistance on the day of the incident to have the car towed. But canceled after the vehicle started back up after 30 minutes with no response.

Driving on the freeway at approximately 70 mph, the car lost the ability to accelerate and started to lose speed. I had my foot on the gas but the speed was dropping. There were no warning lights, messages, or other alerts prior to the loss of acceleration. The screen remained on during the loss of acceleration but a phone call was lost. Safety at risk for obvious reasons. I was able to put hazards on and move to the left-hand shoulder. I turned the car off and on again and was able to speed up again to merge onto the freeway. For the remainder of the drive (approx 25 min), everything was fine. We have not taken the car in yet for inspection. The car charge was over 50%. I had driven the car on the freeway with no issues for an hour earlier in the morning, for 15 min in the city, and then for another 25 minutes on the freeway prior to the incident.

The Ioniq 5 has a serious problem with 12 volt battery drain. Three times, I have returned from vacation and found that the 12 v battery was completely dead. This is a huge issue if a consumer cannot rely on their vehicle to start in an emergency. I called a dealer in Renton, Washington about the issue and the technician responded, "This is a common issue in these types of vehicles." I am sorry, but that is not acceptable and is a vehicle defect. With electronic doors, you cannot get into the vehicle to jump start it, if the vehicle is locked, unless you can pull the manual key from the key fob and open it with the key. 12 v battery drain is killing the lifespan of the battery. Looking on the internet, other owners are complaining of the same issue. My vehicle sat for one week two times in December and I just returned form a two week vacation to find the battery completely dead. I only have 4484 miles on the vehicle and it is a 2023 car, so it is not an old battery. The car has a serious electrical defect.

The car proceeds by itself and does not stop even when brakes are engaged. This happened 2 times. Once in reverse and once forward, both caused severe damages to the car. In the forward incident, the driver was wearing seat belt but air bags deployed with impact.

This model has known issue. As I found after it occurred to my brand new IONIQ 5 . It has only 320mi. It had 87% battery and all of sudden it stop on road. No power on dashboard. After taking to service station they found “ "Inspected and found code P1A9096- DC/ DC converter input voltage sensor fail. Referenced campaign 997 for concern. With code present, per TSB, replace ICCU and fuse." This same issue I noticed in 2022 after reading forum. After putting my car in service station still I don’t have my car. It’s almost 17 days. If this car had recall I could have saved my time and unnecessary effort. Plus thank god it was local city read( school zone) if I was in highway and same thing happen to me it might be life threatening situations.

The following is an incident that happened yesterday to my wife, who is an experienced driver: Whilst driving south on I5 from Seatac toward Tacoma in heavy rain with surface spray the screen above the steering wheel mentioned collision avoidance was not working and radar was not working. When I applied the brakes to slow down no response from the brakes. I then let off the brake and tried several times to apply the brakes each time with no success. I still had full control of the steering and could still steer the car. This lasted for about 30s then the brakes started working again. The error messages regarding collision avoidance and radar not working would continue to pop up even after the brakes were working. After stopping the car and turning it off and restarting several hours later the car no longer displayed any error messages. No vehicle or passenger were hurt in this incident, however if the traffic had slowed or stopped this outcome could have been very different.

The car does not switch from Reverse to Drive under certain conditions, resulting in uncommanded reverse motion. Gear selection on the Ioniq 5 is controlled by a twisting knob at the end of a stalk on the steering column. Drive is selected by turning upwards, Reverse by turning downwards. The moving part springs back into the neutral position once a gear is selected. Occasionally the car does not switch from Reverse to Drive. This is extremely dangerous as the vehicle shoots backwards when the driver is expecting it to move forward. A driver will likely press the accelerator more firmly after having physically moved the gear selector to Drive and expecting the vehicle to move forward. Since this happens after backing up, it is likely that obstacles or persons are behind the car when this happens, and absent a very fast reaction by the driver this will result in accidents and injuries. The issue is triggered when the car is not at a complete standstill when Drive is selected. Even barely noticeable residual backward motion triggers it. There is no haptic feedback to alert the driver that the car ignored the driver input. As drivers are expected to pay attention to their surroundings when maneuvering, visual feedback (via the gear indicator on the stalk and possibly a dashboard notification) is not useful. There is a small auditory cue, but it is easily missed when in a conversation or listening to music, especially because the car frequently dings, pings, and beeps for other reasons. Not to mention, hearing-impaired drivers will also miss this. The driver should not be able to physically move the gear selector into the Drive position when the car is not accepting that input - the twisty bit should be locked out to prevent this. Or at the very least, if a crucial driver input is discarded, the car should instead default to a safe behavior, i.e. put the car in Neutral instead of Reverse.

- #11554852November 13, 2023FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I'm surprised there are no safety recalls on this vehicle given how Cruise Control operates & how close to the Cruise Control toggle switch the steering wheel is indented for hand placement at 10 a.m./2 p.m.We purchased a 2023 IONIQ 5 on 02/25/2023.When the vehicle was delivered to us we were not told that the cruise control does not disengage when the brake pedal is applied.It merely pauses.There is nothing in the owner's manual that addresses cruise control operation.In any other vehicle we have owned, including other Hyundai vehicles, cruise control cancels when the brake pedal is depressed.Without proper training/information & without cruise control being addressed in the owner's manual we had no way of knowing this.2 months after purchasing the vehicle, while pulling into a parking space driving 3 MPH I stepped on the gas & the vehicle returned to the previously set cruise control of 45 MPH.Whereupon it went over a parking bumper, landscaping, curb, $ into a busy street, scraping the passenger rear portion of the vehicle & damaging the wheel.We took the vehicle to the dealership, Larry H. Miller on 05/03/2023. They were unable to duplicate the mishap.The GM of the dealership indicated that in all probability what occurred was inadvertent touch of the toggle switch.He indicated that this unique cruise control operation was experienced by others, including himself.On 05/24/203, he recommended we contact Hyundai Motors USA to report the incident.Doing so resulted in numerous phone conversations, emails, and 2 inspections of the vehicle. Finally, on 10/19/2023 we were advised in a HMAUSA letter of resolution that said, "no manufacturing defect was identified." They are refusing to pay the $2,247.92 repair bill (on 04/26/23.May be higher now due to rising costs.)We maintain the incident occurred due to a design flaw & unique cruise control operation.We not only want Hyundai to pay for the repairs, we want the NHTSA to investigate so this won't happen to anyone else.

When driving my new Hyundai ionic 5, the dashboard display is set up such that when I am in my preferred seating position, and my hands at 10 and 2 on the steering wheel, I cannot see the spedometer reading. I basically don't know how fast I'm going and less I change my hand position or move my head. This requires a fair more amount of time for me to take my attention off the road. This is not an isolated incident. I have asked my friends, who range in height from 5'2 to 6 ft 3 to do the same thing. They all report the same problem when they are in their preferred seating position. I am also noted many complaints about the same issue on the ionic 5 internet boards. This problem is caused solely by Hyundai's choice of a main display layout. This is the way it is laid out from the factory, and there is no way to change the speedometer position on the main display as a user.

The car driving selector order is Drive, Neutral, Reverse which is the wrong order. It should be Reverse, Neutral, Drive, which is the same for all the cars I have driven since the late 1960's. In fact, the Hyundai Santa Fe has the correct order. Also, my Volvo XC60 has the correct order. I thought that your standard 571.102 addressed this problem. I am having the same problem selecting the wrong drive when I go from my Volvo to the Ioniq 5.

I started getting the error Electric Vehicle System error in my month old Ioniq 5. After driving a few miles, the air conditioning stopped working completely. And after a few more miles, the vehicle started to throttle down the speed to 20-25mph that too on the I95 with a 65mph speed limit. Had to turn on the emergency lights and drive slowly till I reached my destination. After googling for a while, I found that this issue is related to the ICCU failure that is pretty common in the Ioniq 5 and Hyundai is yet to issue a permanent fix for this problem. I don’t know why we are allowing the sale of these vehicles with known issues. You can even Reddit the ICCU issue.

Driving on freeway when adaptive cruise control turns off and had a sudden complete loss of acceleration, we had steering and brakes only. Sudden reduction of car speed in traffic could cause accident. Has only happened once in 20k miles. (no acceleration) Adaptive cruise control shuts off for no reason, but dealer couldn't replicate. In recent 8k trip we photographed warning on dash 17 + times after shut down. Dealer couldn't find any saved trouble codes for this. No warnings prior to any occurrence only after, dash turned off on acceleration loss.
