While driving my 2023 Hyundai Tucson PHEV with limited trim the Emergency Braking function activated for no reason at all. This has happened 5 times during the last 9 months and each time it was about the same conditions. Road was dry my speed was from 55 to 75 mph it was during daytime hours and no cars were in front of me or on either side of me. 3 of the times there was a car behind me that had to check up I guess because my brake lights came on. I reported the problem to the dealer and was told no other owner has ever reported than problem. Instead of preventing an accident the activation of the emergency braking system in this situation could have caused an accident with the cars around me reacting to my sudden braking at high-speed resulting in a chain reaction.

Automatic Emergency Braking deployed without any external threat. I was driving 55 mph on the freeway and the automatic emergency braking engaged. The dash lights flashes, there was an audible alarm and the car braked. There was no danger in front of the vehicle and this action put me at risk of being hit from the rear by the car behind me. My safety was put at risk as my acceleration was greatly diminished compared to the traffic around me. There was no warning of the problem prior to the failure. It has not been confirmed by the dealer.

On Tuesday August 6th 2024 car was put in the shop for an automatic DTC notification/check engine light. Our car is less than a year old with less than 10,000 miles on it. Our car was in the shop for a full 5 days and was given to us on the evening of Monday August 12th with assurances that it was safe to drive. While in the shop, our car grounding pump and numerous fuses were replaced. On Friday August 16th, we received a jarring "Check Hyundai system. Stop Safely." message while driving a short distance. We were given roughly 5-10 seconds before the car braked and stopped, causing us to almost be rear ended from the car behind us. This put not only me and my passenger's safety at risk, but the safety of the cars nearby us at that time, at risk. We shudder at the thought of what could have happened if we were traveling on a highway or congested roadway. There were no warning lamps or symptoms that would have suggested this would happen. We received a tow to the shop early morning of August 17th and to date, the car remains in the shop. We are confident that the car will not pass it's upcoming inspection and have requested that the service dealership perform an inspection before they attempt to give it back to us. I feel strongly that we are not safe driving this vehicle. Our local Hyundai service dealership employees have implied that they feel a recall of this car is forthcoming because they have begun to identify this issue in many cars. Given Hyundai's recent track record with recalls, I am extremely concerned for my safety.

Car was completely dead. Because it is a PHEV, wheels were locked and the vehicle needed special equipment to be towed. Tow drivers (3 trucks eventually came) couldn't jump or charge the 12v battery. Traction batteries had a good charge. Locked wheels and sudden loss of all power makes this a safety issue.

New 2023 Hyundai Tucson purchased 9/9/2023 from Curry Hyundai in Cortland NY. On several instances of highway driving during the first 1,000 miles, on highways and at highway speeds, the forward collision avoidance system activated without any reason and applied the brakes at highway speed. This happened 6 or more times in only 6 or 7 highway trips during the 1,000 break-in period, and happened after the first visit to service for this problem, during which the dealer reset the system and sent me on my way, only to leave me driving a vehicle with the same, continuing defect. After the third service attempt, dealer and Hyundai have been unable to repair the vehicle (now with the dealer for over a week). Hyundai fails to even acknowledge its warranty or any other obligations to me, and all its communications show that it doesn't take these problems seriously, it has no standard process for dealing with them, and it offers basically nothing to the frustrated car owner. All its "customer care" department has done is check with the dealer, only to leave the problem with me for an unlimited timeframe.

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.

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.

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.
