2022 Hyundai Ioniq 5 Complaints

In summer 2025, the ICCU (Integrated Charging Control Unit) failed and was replaced under a Hyundai recall at no cost. On December 4, 2025, warning lights reappeared. College Park Hyundai diagnosed a faulty battery related to the prior ICCU failure. I paid out of pocket for a 12-volt battery replacement and additional maintenance, as the dealership claimed the battery was not covered. A “Check Electric Vehicle System” warning appeared immediately after I picked up the vehicle that same day. On December 5, 2025, I returned the vehicle to College Park Hyundai with 20,415 miles. They diagnosed a failed main EV drivetrain battery requiring warranty replacement. As of April 5, 2026, my vehicle has been at the dealership for 122 consecutive days with no repair completed, no replacement battery received, and no estimated completion date. Despite repeated follow-ups, I have received no meaningful updates on repair status or battery availability. I have been without my vehicle for four months w...

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 to control. Initially had the tires re-balanced in an attempt to fix before the problem was fully understood, but that solution did not last. Ultimately had the tires dismounted and foam pulled out, then rebalanced.

Upon starting the car, it made an audible "pop", and the dash indicated to check the 12V power supply and "low available power" with a turtle indicator, and an "EV!" warning lamp. The car struggled to accelerate out of the parking lot, and within a minute, the dash displayed a "power failure" message, and the car lost all ability to accelerate while on the road, forcing an emergency pull-over. The 12V system completely failed while waiting for a tow truck, complicating the already poorly-documented and complicated process of disengaging the vehicle's automatic parking break for loading onto the flatbed trailer. The dealership performed diagnostics and confirmed an ICCU failure. After waiting for parts and technician availability, the ICCU was replaced with part number 36400-1XAA0-AQQH "ICCU Assy" and returned to me 32 days later.

I am filing this complaint regarding Hyundai Motor America's failure to complete a vehicle repair in a timely manner on my 2022 Hyundai Ioniq 5 (VIN: [XXX] ), which has been at Hyundai of Leander, an authorized Hyundai service center in Leander, Texas, since September 2025 — more than six months — awaiting a replacement high-voltage battery. (Case No. XXX) I purchased this vehicle in September 2025 from Apple Sport Imports in [XXX] . The vehicle was sent immediately to Hyundai of Leander for an open repair and I never took full delivery. I was informed the replacement battery was initially allocated to a different dealership and a new order could not be placed until approximately January 2026. As of March 2026, Hyundai's own case manager confirmed in writing on March 30, 2026 only that they are working to determine the battery's arrival date with no confirmed completion date provided. Since November 2025, I have made 5 monthly payments of $513.92 totaling $2,569.60 on a vehicle I have...

On January 19, 2026, the vehicle lost power while driving and required a tow to the local dealership. After inspection, the dealership determined that the ICCU was at fault and needed to be replaced. The ICCU part was backordered. The vehicle was inoperable for 6 weeks as we waited for the part to be available and installed.
