Throw out bearing leak, resulting in excessive loss of brake fluid and potential for reduced braking ability. Low brake fluid warning light illuminated and was reported to Suburban Hyundai of Troy around 6,000 miles and again around 10,000 miles. Dealer confirmed leak was occurring at throw out bearing, and impacted clutch friction material as well, which could result in a potential inability to accelerate depending on fluid accumulation on clutch. Upon confirmation, dealer replaced throw out bearing, clutch, and perfomed brake fluid flush.

I had turned onto my road when I had to stop just before pulling into my driveway to park when my neighbor began backing up. I saw he was getting close to my vehicle so I began to hit the horn only to find out that it’s inoperable. Unfortunately, since my horn wasn’t working, my car ended up getting hit. Earlier this past week, I had just received a letter in the mail from Hyundai explaining they were extending the warranty on the horns for my model. If my horn was operable at this time, this accident could have been avoided. • the horn failed to operate when I went to hit it to get the other drivers attention only to find out it’s inoperable. • my safety could have definitely been more at risk if it were a higher impact situation. Thankfully it wasn’t. • the problem was acknowledged by Hyundai of America to the point that they sent out extended warranty notices to vehicle owners of my year and model vehicle. But I feel as though this should be a safety recall rather than a than an extended warranty notice. • the last time the horn was inspected by my local Hyundai dealer was in October 2024 during the routine NYS inspection. • there were no warning lights or notification in the computer system in my vehicle stating that my horn had stopped working. I had found out my horn wasn’t working in that very instance when my vehicle got hit by the other vehicle.

Hyundai dealership “fixed” the recall on my car a few weeks ago. This morning my car stalled out on the highway twice due to fuel pump issues, one of those resulting in my car hitting a guardrail. Every warning light went on in the car and a service message to make an appointment at the dealership popped up. I do not believe this vehicle is safe to keep using

I find myself in this situation due to a defect in my 2023 Hyundai, which is under Full Factory Warranty. I have had all my required services completed by Hyundai on time, and as the consumer had no idea anything was wrong with my vehicle. On 31 August 2024, just 25 days after being service by Hyundai Yuma on 6 August 2024, this defect caused a catastrophic failure in my front driver side tire resulting in damage to my vehicle. My vehicle was towed to Hyundai Yuma on 1 September 2024, by Hyundai Roadside Assistance. After an inspection by Hyundai Yuma on 5 September 2024, it was determined that there was a defect in the camber of the alignment of the car that caused the catastrophic tire failure, damage to my vehicle's front skirt and bumper, as well as premature wear on all three existing tires to the point in which they are not safe to remain on the car. The only solution to this defect according to Hyundai Yuma is an Aftermarket component to correct the defect in the camber of the vehicle. Without this Aftermarket addition to the vehicle, the camber would remain out of specifications causing premature wear of any tires placed on the vehicle thus making it unsafe to operate. Therefore my car is currently inoperable and beyond my control

This bulletin provides information related to a Transmission Control Unit (TCU) software update for some vehicles equipped with an 8-speed wet dual clutch transmission (8WDCT). The software update revises the touch point learning variation, improving drivability and judder symptoms. Certain 8WDCTs (indicated by a new part number) received an updated clutch spring. The correct TCU software update must be matched with the correct corresponding 8WDCT hardware, otherwise, drivability concerns may occur. This service procedure should be performed prior to any 8WDCT replacements done for drivability/judder concerns.

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.

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).

Some Elantra (CN7/CN7A), Elantra N (CN7 N) and Elantra Hybrid (CN7 HEV) vehicles may experience the following conditions: • Lack of airflow coming from the forward-facing center vents • Mode actuator not changing airflow direction after various inputs • Popping/snap noise when switching between different modes If any of the conditions above exist, follow the repair procedure in this bulletin to replace the ventilator lever and cam mode guide.
