2022 Hyundai Ioniq 5 Maintenance Schedule

“Less than 48 hours after getting the latest Integrated Charging Control Unit (ICCU) recall performed (Hyundai Recall Number 272, NHTSA Recall Number 24V-868), the ICCU on my car failed…”

“The ICCU has failed. This component was replaced approximately one year ago as part of a recall, but it has failed again. The vehicle is currently parked and cannot be driven until Hyundai provides a replacement part, which may take up to three months…”

“The ICCU failed to charge the car via level 1 (120VAC or 240VAC), but does charge using public DC chargers. Fortunately the issue occurred at home so no traffic issue occurred, in this case. The level 1 charger indicated a fault and would not charge the car…”

“The Dealer states my ICCU has failed and will be replaced. My vehicle could no longer charge on AC power (level 1 or level 2), and eventually had to be taken to the dealer because it could not be charged at home any longer due to the ICCU failing.”

“Unknowingly my cars ICCU failed. I went to charge my car on December 23. The EVSE then immediately tripped the breaker. The EVSE gave an error code of a stuck relay fault and made the EVSE unusable. This happened to 2 different Juicebox chargers…”

“While charging at home with provided Level 1 Charger, the vehicle will suddenly stop charging. When it stops, it appears to be surging an electrical charge back into the home (black marks on outlets requiring an electrician to replace, black marks on the charger plug…”

“While driving my IONIQ 5 it flashed a power limited warning, went into turtle mode, and then experienced a total loss of power. The 12V battery was dead.”

“ICCU Failure . Car stopped in the middle of the highway. I was able to move over thankfully to the side of the rode. Went into turtle mode and then it had to be Towed to my local Hyundai Dealership”

“Multiple 12v batteries died within one year of installation; ICCU finally failed at about 3.5 years of ownership. Towed to dealer on January 16, 2026, still no repair as of February 24, 2026.”

“12 V battery died after being plugged in to charge overnight. The 12V battery was replaced in May 2024 due to a similar issue. It seems that the ICCU recalls and software updates have not been fixing the problem.”

“The contact owns a 2022 Hyundai Ioniq 5. The contact stated that after the vehicle was parked on a slight incline on the road, the gear shifter was shifted to park(P), and the vehicle was turned off. The contact stated that while exiting the vehicle, the vehicle started to roll…”

“When you place the car in park a recall was done so that the emergency parking brake automatically engages. Well between 30 seconds to a minute after the car is in park, the brake disengage. When you go to set it manually after it disengage, it will still disengage.”

“Factory installed Michelin Primacy AS tires with acoustic foam lining. All 4 tires had acoustic foam coming loose and wadding up inside the tire, resulting in extreme vibrations (similar to a severely unbalanced tire) approaching and at highway speeds making vehicle difficult…”

“A severe vibration started suddenly in the steering wheel and persisted between ~55 and 65mph. The first occurrence almost caused a crash on the highway and significant driver input force was needed to control the car…”
