[XXX] - Took Hyundai IONIQ 5 to All Star Hyundai Pittsburg for servicing and recall issue. [XXX]: Saw an error reading CHECK ELECTRIC VEHICLE SYSTEM! on the IONIQ 5, after which a BlueLink rep was connected and stated I needed to take the car to a dealership ASAP. No appt available until July so advised to take car back to All Star. Called All Star and spoke to Josh who said there were no appts until [XXX]. Arrived All Star 9:15. I stayed until 3:15 with a lot of back and forth on diagnostics, warranty, how long for repair etc. Called Hyundai Customer Care and spoke Stephen who said the car was purchased less than a year and it would be under warranty for repair. I spoke to David, Manager All Star, who said he does not know when the diagnostics will be complete/ when car would be ready. Told me to go to Enterprise and get a rental at my own expense. Went to Enterprise Pittsburg in an Uber paid for by All Star. When I got there no cars available. Called All Star multiple times NO ANSWER. Took an Uber back to All Star to retrieve items in car and took Uber home at my own expense. Wednesday, went to Enterprise to obtain rental at my own expense and returned to All Star. They said they were waiting on Rep to further review the car. Today is May 28th and my right knee is now very painful and irritated from driving the rental as the 1st one had broken drivers seat and the 2nd one is still too low. I have spoken to All Star and Hyundai Customer Care to please provide a car rental similar to IONIQ 5 and I have received no assistance. I have spent almost $2000 on Ubers, rentals and gas. Hyundai still has not covered my rental expenses. I have spoken to approximately 16 reps of these companies and have received very few call backs or assistance. Today I called Hyundai Motor Finance to discuss monthly payments for a non-working car at All Star and was transferred and placed on a lengthy hold. No one returned to the phone call. I am seeking your immediate assistance. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM

The integrated control unit (ICCU) failed immediately after getting the safety recall software installation. Recall maintenance that morning, ICCU failed that afternoon.

- Bellevue, WA, USA

ICCU failed post software update. Driving home and was suddenly alerted electrical vehicle systems were malfunctioning, and shortly following (1 or 2 minutes), the car flashed a new warning telling me to stop the vehicle. Had I been on a busy highway or a one lane street with low visibility, it would have put me and my wife in danger of being struck by other traffic. Luckily, I was very close to home so I drove home and did not drive the car for a few days. while researching what to do, I had read about the ICCU failure and my problems were similar. I called a tow truck to get it out to a dealer. When attempting to shift the card into drive or reverse, the car would not move. Dealer has determined that my ICCU is in fact bad and is currently in the shop being replaced. Unknown how long this will take.

- Winston Salem, NC, USA

both the 12v battery and the ICCU failed while driving. The dashboard light gave us 1 minute to pull over before the battery system died and the car stopped fully dead. Needing towing to dealership service.

I was driving 45 miles per hour on a 2 lane highway, when the car suddenly started beeping, lurched, and dropped to 25 miles per hour (low power mode). After pulling over at a gas station, I was able to run the car in this low power mode for a short time, and then the 12V battery completely died. The main battery in the car was at 78%. There was no warning light that this would happen before making that drive. I took the car in to the dealer and they informed me that the ICCU failed. I see that there is an investigation underway for the 2022 Ioniq 5, and that the 2023 Ioniq 5 has the same components. Please take this investigation seriously as if I were going on a faster highway or more cars were around, it could have resulted in a major accident. This car has just over 10,000 miles and was just purchased under a year prior at the time.

First indication something was going awry was when attempting to charge the car. Heard normal click indicating charge had started, but no audible announcement that charging had started. Car started throwing "Check electrical system, " then power plummeted and became unresponsive to accelerator, followed by "Stop car. Check electrical system, " then finally something like, "Battery is being discharged by external devices."** Car had to be towed about 60 miles to nearest Hyundai EV service center. Eight days later, I got a call from service saying that the ICCU needs to be replaced. They will update me once ETA of part is known.

Electrical system warning lights came on and loud alarm indicating the need to stop the vehicle immediately. Diagnosed by mechanic as ICCU failure and associated 12V battery issues-?"so, typical Ioniq5 problems. Just lucky I wasn-??t driving on the highway.

- Woodinville, WA, USA

The vehicle made a loud popping noise and lost motive power. Dashboard lit up with battery symbol and said to check electric vehicle system. Dealer service is certain it is an ICCU failure. The vehicle had the software update to -??fix-?? the ICCU issue thousands of miles ago.

12v battery died this morning. The car main battery had 77% state of charge and still the 12v failed. The main battery is supposed to charge 12v as long as it is above 20% state of charge. This seems to be a wide spread problem and Hyundai is not taking any pro active steps in resolving this. All recommended TSB (Technical Service Bulletin) has been applied on the car and car was serviced last week and passed the multipoint inspection.

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.

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.

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.

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.

Intermittent Electrical / Brake failure. Put vehicle in reverse. Brakes failed to stop vehicle. Vehicle has had electrical issues before. Waring lights came on for steering and tire pressure in the past. Recall then came from Hyundai for the ICCU.45 minutes before the collision, the front collision warning came on when I was stopped at an intersection with no one in front of me. I stopped the vehicle and turned the vehicle off. Turned on the vehicle and it reset the warning lights and sounds, and I continued to drive. Later while pulling out of a parking space in reverse, I stepped on the brakes but the vehicle did not stop. I pumped the brakes to no avail. After the collision, the brakes worked again when the tow truck driver placed the vehicle on the flatbed.The Hyundai dealer, after the vehicle had been in their possession for several weeks with the battery disconnected, said there was no problem They also had a factory rep look at the vehicle and he made a report. We have not been able to get a copy of the report. Vehicle is still at the dealership. When notified by the factory rep of their claim that the vehicle had no problems, the vehicle had been out of service more then 30 days.

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.
