Hyundai Ioniq 5

"TSB: 23-EV-003H; There is a problem charging the car at 48A. Hyundai fails to fully address this problem. The safety measure drops the charge down to roughly half the kW/h, which means double the charging time. I purchased this car as Hyundai claims and constantly advertises that this is the fastest charging car on the market. Hyundai claims the car can charge 48A/11Kw/h using a level 2 home charger. The vehicle fails to charge at this level and often stops charging all together. I have complained about this to Hyundai and they do not take this seriously. Something needs to be done about this charging problem and lack of accountability."

"Have to reduce charging rate to prevent overheating."

"The onboard charger would not accept a charge from a level 2 or 3 charger. The entire onboard charger had to be replaced."

"Known issue that charging port overheats in hot weather and car would stop charging. Hyundai released a bandaid software fix that now slows charging when port gets hot thus slowing charging speed. Vehicle no longer charges at advertised level 2 charging speeds and takes longer to charge. It wasnt really a fix from Hyundai but more of a way to get out of repairing actually problem"

"The ICCU on my 2023 IONIQ 5 Limited (odo 11,096) failed on March 5, 2024. It had to be towed to the nearest Hyundai EV service center, about 60 miles away, in Killeen, Texas. Picked up the car on March 21 after they replaced the ICCU (36400-1XAA0-QQH) and high voltage fuse. This problem incapacitated the car. I also learned my failure coincided with a major recall that entailed replacing the unit and a related software update."

"After 4 months of charging at 48A the car would stop charging. I reduced it to 35A and it charged without issue for about 10 months. After that it stopped charging even at 32A and now I have to reduce my amperage to 28A to charge it without it cutting out."

"Icca"

"Typical charging problems in the cold weather and the range drops significantly in the cold weather"

"ICCU failed at around 7700 miles after having both software updates to try and prevent the issue. Car was out of service for 2 months while waiting for parts"

"ICCU failure, to be replaced by the dealer."

"Cover came off one of the plug in ports. Ordered a new part and fixed in a week. No problems"

"AFTER THE ONBOARD CHARGING UNIT WAS REPLACED, I HAVE HAD CONSTANT PROBLEMS WITH THE 12-VOLT BATTERY DISCHARGING. I HAVE JUMP-STARTED THE CAR SEVERAL TIMES."

"It charges for a short period of time and then the charging fails."

"When the weather became warmer last year, the car stopped charging on its own. Although the Hyundai dealership said they were unaware of any problems, I found a website ( The Ionic Guy) that described the issue and found a problem sheet from the car company that I was able to take to the dealership for a repair."

"Rear cargo latch rattled; they replaced with upgraded new part"

"Noise over bumps in rear of vehicle. Found service bulletin for problem online and had rear hatch hardware replaced"

"A rattle began coming from the trunk in March 2024. The noise happens when i go over small bumps or potholes. Hyundai had a TNB for issue which I took in to resolve. The fix worked for one day."

"Tailgate rattle. Dealership installed paper washer that didn't work. 3D printed 1 mm washers and install self. Fixed the problem"

"Rear latch was not hold the door closed tightly so was replaced"

"Apparently a well-document problem, a metallic clicking sound seems to be coming from interior rear of the car. Hyundai replaced the sunroof assembly, which did not correct the problem. Now my dealer says that a team of Hyundai engineers have been called to analysis and troubleshoot the problem."

"Trunk rattles when going over bumps. Known issue with the cars though dealers often make the problem worse so I've just lived with it"

"12V battery died completely about 10 months after buying the car. I would have to jump the car with a portable jumper each time I started it. Got the 12V battery replaced under warranty."

"Adaptative cruise control doesn't always stop with stopped cars in front me. Braking and acceleration are significantly too aggressive"

"Brake lights don't activate when slowing down without removing foot completely in single pedal mode"
