The car horn malfunctioned. I was not able to warn other drivers I was approaching and they were about to hit me. The component was inspected and replaced over a year ago in May 2024 under the vehicle warranty. No warning lights appeared when it happened.

FUEL/PROPULSION SYSTEM

As I was driving home from work, a loud POP went off under my car, and sirens began to go off. I was given a critical error, and told to immediately contact a dealership. My car began to slow, and would only go 25 mph. Luckily for me I was within a few miles of a dealership, but if I wasn't so fortunate this would have been a much larger issue. The ICCU has failed, despite already getting Hyundai's recall for this issue performed. I am now without my car for an unknown quantity of time.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

I was crossing the Mackinac Bridge, northbound, this afternoon, at the time traveling over the bridge deck's grates in the left lane. Traffic was backed up and I was traveling in the single-digit MPH. There was more that a car's length between myself and the next car ahead, and as I accelerated a little bit to close the distance my emergency braking activated. Fortunately, the car behind me was trailing by a little bit and was also traveling slowly.

ELECTRICAL SYSTEM

I own a 2024 Hyundai Ioniq 6 that experienced a complete 12V battery failure at under 500 miles of use, despite showing normal voltage levels (12.5V off, 13.25V while attempting a jump). The vehicle was undrivable and could not start, even though the main battery (MV) was at 70% charge. There were no prior warning lamps or messages before the failure. The vehicle had to be towed and left inoperable for nearly 30 days. According to the servicing Hyundai dealership, the root cause was determined to be a failure caused by Hyundai’s own connected app, Bluelink — which the dealer explicitly said is the root cause for my batteries failure. Hyundai Motor America, however, has refused to acknowledge this diagnosis, and despite repeated inquiries over a 60-day period, has not provided any explanation or confirmation of the cause. They continue to point back to the dealer while providing no warranty-related answers, no documentation of testing done, and no safety assurance that the failure won’t recur. The issue puts safety at risk, as the 12V battery’s failure renders the entire EV completely disabled — without warning. This creates potential for owners to be stranded, especially if the issue occurs in unsafe or remote locations. In my case, roadside assistance failed to be able to pick up the vehicle twice, resulting in a 12-hour ordeal. Hyundai has made no effort to formally investigate the potential connection to Bluelink and appears to be suppressing acknowledgment of the defect trying to offer me a one month payment instead of acknowledging or confirming this is a possible issue that can happen again in the future contingent on me saying my concerns are resolved; they're not. The resolution involved a tech having to use a third party tech line & no data within the invoice. I believe this is a broader safety issue affecting other Hyundai EVs using the Bluelink system and that NHTSA should investigate whether this poses systemic risk across affected vehicles.

ICCU failure. EV car flashed battery issues and could not drive. ICCU and 12 volt battery replaced after 10 days in dealership shop. Manufacturer inspected. Prior to issue electric hatchback closed half way then stalled. I drove to the dealership and asked them to check if there was something wrong. They closed the hatch manually and said the 12 volt battery was fine and the computer said something blocked the closure, I left the dealership and made it less than a mile before battery light went off (within 5 minutes of leaving dealership). Made it back to dealership in turtle mode and this time computer said the ICCU failed.

FUEL/PROPULSION SYSTEM

When driving the instrument panel displayed a warning message of electrical problem and stop the vehicle. BlueLink displayed failure code P1A9096 indicating ICCVU failure. Drove vehicle to local dealer where the ICCU/fuse was replaced.

Left the house, made it a few miles from the house. Loud pop from the rear seat, warning lights came up on the dash limited power and check electrical system. Was limited to 25mph to drive home. All recalls were done prior to failure. Last recall was done approx 2 weeks prior to failure. ICCU was diagnosed as the failure and was replaced.
