2024 Hyundai Tucson Hybrid

On Monday, 09/14/2026 at approximately 10:15am Mountain Time Utah State Route 36, North-bound. -- I was driving straight, approximately 60mph on dry road on a sunny day. There was no other traffic on the road either ahead, alongside, or behind me and no oncomming traffic. The Automatic Emergency Braking engaged, the emergency braking indicator flashed on the dashboard and the car slowed way down and then it just stopped engaging and the car rolled freely. I believe that the forward collision warning also sounded. NOTE-- this is not the first time this has happened to me. It has happened at least 3 to 4 times over the past two years since we leased the vehicle. I have asked the dealership service department to look at it, but they state that they can find no indication of any problem and that they have been unable to reproduce the event.

I was driving at a low speed (10-15mph) with a safe distance between me and the vehicle in front of me when the semi truck in front came to an abrupt stop. I reacted appropriately by pressing on the brake, however, my car accelerated into the vehicle instead. None of the emergency brake systems activated including the automatic emergency braking and front collision warning, which lead to my car driving into the semi-truck.

2024 Hyundai Tucson SEL Convenience Hybrid Recall:Hyundai Campaign 290/NHSTA 23V-187 (subsequent Tucson tow harness fire recalls) My vehicle was brought into an authorized Hyundai dealership to address the safety hazard associated with the accessory tow hitch wiring harness recall. The dealership resolved the immediate fire hazard by completely disconnecting and removing the functional trailer wiring harness from my vehicle. My physical repair invoice explicitly states: "repair complete-disconnected the positive connector and removed OEM harness from the vehicle, installing a dust cap." No replacement harness was installed. Because this physical removal occurred, Hyundai's internal corporate warranty system has offically marked the safety recall as "Closed" and completed for my VIN. However, the manufacturer has failed to provide a safe, functional remedy to restore the vehicle's advertised and purchased towing utility. When checking with Hyundai Customer Care, I am told the redesigned waterproof harness (Part #CWF61-AU100) cannot be ordered or allocated to my vehicle because the computer systems views the safety risk as resolved and the recall closed. I called Findlay Hyundai in St. George to see if they had the part number CWF61-AU100, he said he did not but Ontario had some & could get the part in a few days. The manufacturer's remedy is inadequate. By permanently removing a functional utility to satisfy a safety metric, without providing a safe, operating replacement part. Hyundai has effectively disabled the towing capabilities of my vehicle without offering a true remedy. I am requesting that NHSTA compel Hyundai to reopen or provide a distinct parts-allocation path for vehicles that had their wiring harness removed rather than replaced.

On XXX we were driving from [XXX] to [XXX]. Going through the [XXX] mountains on [XXX]. At an elevation of about 6,000 ft. temperature was about 85, speed about 55 mph the window in the back seat (behind the driver) imploded with a huge bang (sounded like a bomb went off). Glass was all over the back seat. I thought someone had shot at our car. I was with a retired CHP and he confirmed no bullets or rocks - this window just spontaneously exploded sending glass shards like shrapnel in the car! Besides the noise of the explosion, which could have caused the driver to veer off the road, if anyone had been in the back seat they could have been killed or seriously wounded from the flying shrapnel. In talking with other people, I found out NHTSA has an open engineering analysis (DP23001) investigation regarding this issue. This is very serious and should NOT be allowed to happen. Appears there is defective glass in some Hyundai Tucson's - not sure if the pressure of going over the mountains had anything to do with it or the design of the car but I'm leery of driving this car now! Thank you for your time and hopefully the manufacturer will correct this issue ASAP or before someone dies. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I own a 2024 Hyundai Tucson hybrid SEL with a genuine Hyundai trailer hitch & trailer wiring harness that were installed by a Hyundai dealer. My vehicle was included in Recall P90. As part of the recall, the dealer disconnected & removed the wiring harness because Hyundai did not have an approved replacement available. As a result of the recall, my trailer lights no longer function. I can no longer legally or safely tow my boat trailer because the trailer has no brake lights, turn signals, or running lights. Before the recall, the trailer wiring worked properly. I contacted Hyundai Customer Care & requested an approved replacement wiring solution at no cost. I explained that the recall removed a factory-approved, dealer installed towing function but did not provide a remedy that restores the vehicle's towing capability. Hyundai advised me that no replacement remedy is currently available & would not escalate my concern. I believe this is an unreasonable lack of remedy for a safety recall. The recall has left my vehicle unable to safely perform the towing function for which it was equipped. I am requesting that Hyundai provide an approved replacement trailer wiring solution that fully restores the original towing capability at no cost to owners. No repair date is given for this repair.

Some Palisade (LX2), Tucson (NX4), and Tucson Hybrid (NX4 HEV) vehicles may experience battery drain due to continuous operation of the cooling fan after vehicle ignition has been turned off, potentially resulting in a no-start condition. The continuous cooling fan operation is caused by a stuck relay in the engine room PCB block. This bulletin provides instructions to replace the engine room PCB block to ensure the proper operation of the cooling fan.

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.

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.

Some 2019MY and newer vehicles equipped with a front view camera may illuminate certain warning lights and trigger DTC C272246 fault code for the front camera. In the following cases, the front camera auto-calibration range may be exceeded while driving: • If the front camera is not properly installed and is completely or partially detached. • In case of excessive changes affecting the vehicle's balance (e.g., loading excessively heavy cargo in a specific location of the vehicle, or significant under-inflation of the tires). • Specific road conditions affecting the vehicle's balance (e.g., excessive road crown) This TSB provides instructions on how to service the vehicle when the front camera related warning light(s) are triggered due to system out of calibration (DTC_C272246).

This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.
