2025 Hyundai Kona

The dash will completely go black except for red words *no signal.* and all warnings are no longer visible, I cannot tell what speed I’m going, or what percentage battery my car is at. I don’t see visible lane or collision warnings. It is very unsafe and I have been to the dealership twice to try and fix it. The issue returned both times.

I purchased a used Hyndai Kona with 26,000 miles April 30 2026. I was told I have the balance of the manufacturer warranty of 5 years or 60,000 miles. I have not driven my car for 73 days because of extreme safety problems the Hyundai Kona. The car is very difficult to steer. The car pulls significantly to the right. One day after I purchased this vehicle the car jumped the curb and my face hit the steering wheel cutting my nose and creating a black eye. There is a lot of play in the steering wheel. When accelerating from a stop the car hesitates to move creating a safety concern. My rear view mirror does not stay in place. The mirror drops down and I cannot see behind me causing a safety concern. Both side view mirrors have to be adjusted each time I drive the car.

Component or System: The brake system, specifically what appears to be a false ABS activation or IEB (Integrated Electronic Brake) system malfunction. The component is available for inspection upon request. Safety Risk: While braking at speeds between 25-40 mph, typically on dry pavement and more frequently on downhill grades, the brake pedal exhibits a chugging sensation, erratic stopping behavior, and pedal softening consistent with unintended ABS activation or IEB malfunction. This occurs on dry roads where ABS activation is neither warranted nor expected, creating unpredictable braking response and extended stopping distances. The defect has occurred 24 documented times since [XXX], and existed prior to that date. Dealer Confirmation: Yes. During a ride-along at Edmond Hyundai on [XXX], a technician directly witnessed and confirmed the occurrence. Despite this confirmation, it was not documented on the repair order. Two prior repair attempts returned cannot-reproduce results: March 2, 2026 at Bob Howard Hyundai and March 10, 2026 at Edmond Hyundai. Additional Repair/Inspection Attempts: On April 7, 2026, Norman Hyundai opened and closed a repair order without the consumer's knowledge and refused to provide a copy despite an explicit request. On May 23, 2026, a scheduled appointment at Bob Howard Hyundai was missed; a reschedule request was subsequently ignored by the dealership. HMA Case No. [XXX] is active. Warning Lamps or Prior Symptoms: No warning lamps have illuminated. The defect presents exclusively as a physical sensation—pedal/brake chugging, softening, and erratic stopping during normal dry-pavement braking. The issue has been present since delivery on [XXX].

Some Kona (SX2) vehicles equipped with the 1.6L T‑GDI engine may exhibit false “engine left idling” notifications in the MyHyundai app, even when the engine is not running, due to a logic error associated with the front oxygen (O₂) sensor. This condition may also illuminate the Malfunction Indicator Lamp (MIL) and set DTC P223700 (O₂ Sensor Pumping Current Circuit/Open [Bank 1 Sensor 1]). This bulletin provides instructions to perform an ECU software update to correct the O₂ sensor logic and resolve the condition.

This bulletin provides information related to the navigation and head unit software changes introduced in the 2026 1st Navigation Map and Software Update. The changes may vary depending on vehicle type, model, and navigation system. Refer to the 2026 1st Navigation Map and Software Update Key Improvements and Additional Improvements tables in this TSB for a list of specific changes. The software can be downloaded via Navigation Updater (NAU) and updated by USB.

Some vehicles may exhibit difficulty starting in cold weather. This bulletin provides the procedure to perform an inspection on the starter magnetic switch for potential freezing and, if necessary, replace the starter magnetic switch (solenoid) assembly.

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.
