Vehicle: 2026 Hyundai Ioniq 5 Description of Safety Defect:The Reverse Parking Collision-Avoidance Assist (PCA-R) system exhibits a severe software logic flaw that creates an immediate traffic hazard. When a standard, hitch-mounted bike rack is installed, the vehicle’s rear sensors detect the rack as an imminent collision obstacle while in reverse. The system responds by executing an abrupt, violent emergency brake application, bringing the vehicle to an unexpected dead stop. The primary safety failure is a lack of non-volatile memory retention for driver settings. In the infotainment system under "Parking Safety," a driver can manually deselect or disable the "Rear Safety" automatic braking feature to accommodate hitch accessories. However, this setting completely resets to "Enabled" by default every single time the vehicle is restarted. Safety Risk & Real-World Consequences:This defect has caused multiple documented near-miss incidents. Specifically, when attempting to reverse off a main roadway into a driveway with cross-traffic present, the vehicle suddenly slams on the brakes due to the bike rack. This leaves the vehicle unexpectedly stranded and protruding into active lanes of traffic, nearly causing severe rear-end and T-bone collisions with passing vehicles. Requested Corrective Action: Hyundai must issue a software update changing the ADAS memory logic. The Reverse Parking Collision-Avoidance Assist state should persist in the exact state it was in when the vehicle was last turned off (Last-Mode Memory). If a driver explicitly disables the feature to safely operate a bike rack or hitch accessory, it must remain disabled until the driver intentionally re-enables it.

I am a tall driver (6'4") and I need to wear sunglasses when driving most of the time. The eye tracking device seems generally incompatible with both of these conditions. When the eye tracker fails to recognize my eyes are looking at road it disables driver assist features such as lane centering which can occur unexpectedly and has almost caused me to wreck once. I have tried without sunglasses and squinting at the glare also causes the system to fail. I often have to lift my glasses and stare at the sensor to make the warning go away (in effect forcing me to take my eyes off the road. If sunlight hits it, it also fails. So in summary, this device does not work in the daytime. I have contacted the dealer, and they basically read the Hyundai response I've found online verbatim: summarized, you can't wear sunglasses, prescription glasses, be over 6 foot tall and several other conditions and expect the system to work. There is no way to disable the tracker. There is an option the dealer pointed to, but it is ignored when you turn on any of the assist features. Since this system is currently so unreliable, at best, this is an expensive feature I am unable to use. At worst, the distractions it is causing is going to cause an accident. This is an ongoing issue, date indicates first time issue was noticed.

My car would no longer charge after testing various chargers at home and different public charging stations. If this had happened away from home, and without cell service, I might have been stranded. I took I into the Hyundai service center, and they said the ICCU had failed. They replaced if after waiting a week for the part.

Certain IONIQ 5 (NEA EV) vehicles are eligible for a software update to the VCMS which would enable the Plug and Charge (PNC) function to support its use on Tesla V3 and V4 Superchargers, IONNA chargers, and ChargePoint chargers. This bulletin provides instructions for completing a software update to the VCMS.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

Some vehicles may exhibit a loss of connectivity or interruptions in the middle of using Bluelink functions. This may be due to an occasional disconnection on Verizon’s communication network. Follow the procedures in this bulletin to verify Bluelink Data Communication Unit (DCU) network connection and if needed, reset the DCU in Dealer Mode to resolve the connection.
