2022 Hyundai Santa Fe

The horn has now stopped working in my vehicle twice. It was replaced 01/27/2023, and is now non-functional again. I believe this to be a safety issue as I have no way to warn other drivers or pedestrians of my presence, if necessary. One example of this, was that a vehicle was proceeding into my lane on the interstate yesterday afternoon and I had to avoid them hitting my vehicle by driving onto the shoulder of the road, as I could not use my horn to let them know they were coming into my lane while I was on the side of them.

The contact owns a 2022 Hyundai Santa Fe. The contact stated that while pulling out of the driveway and approaching a stop sign, the message "Check Transmission Oil Immediately" was momentarily displayed.

The contact stated that the failure recurred while driving approximately 35 MPH the following day, and the engine power was reduced. The check engine warning light was illuminated. The driver contacted Bluelink and was advised to pull over safely. Bluelink and the dealer advised the driver to tow the vehicle to the dealer for assistance. The vehicle was towed to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The contact associated the failure with NHTSA Campaign Number: 22V746000 (POWER TRAIN); however, the VIN was not included.

This email serves as a formal dispute of the warranty denial issued by [Lester Glenn Hyundai Toms River NJ] regarding the Supplemental Restraint System (SRS) passenger airbag sensor in my 2022 Hyundai Santa Fe.The dealership has refused coverage, attributing the failure to "water damage." I strongly dispute this finding and am formally requesting a Corporate Goodwill Repair Exception or a tier-two engineering review of my vehicle due to the safety-critical nature of this component.

I did a navigation update as requested by the infotainment system on the Hyundai. After the update, the air conditioner would not turn on when the ac button was depressed . I took the vehicle to my local Hyundai dealer and they found the ac blower and ac button working intermittently. After further inspection, the mechanic found the multi fuses that sit on the PCB bloc had one burnt fuse that did not blow and was still hot and the PCB block had melted around where the fuse connected to it. ( Hyundai stated that they required the damaged PCB fuse, the PCB block and the harness). I'm concerned that the electrical short discovered by the Hyundai mechanic could have progress and burnt my car or my house since I keep my car in the garage. The Mechanic working for the Hyundai dealer found the burnt fuses and PCB block and kept them after replacing them with new parts. The ac was working fine until I did the navigation update and there were no warnings whatsoever.

The airbag sensor is on in the car. When I told the dealership they stated that the sensor is not covered under the warranty even though it was over by a fe hundred miles. None of the airbags will deploy if there is an accident. I don't see why a safety issue is not covered by the warranty. For the dealership to fix it, it is going to be over $800.

While driving, my vehicle displayed “Shifter System Malfunction! Service Immediately.” Immediately after, I was unable to shift the vehicle from Drive into Park, Reverse, or Neutral. The only way to park the vehicle was to turn the engine off while it was still in Drive, restart it, and then shift into Park. This is an extreme safety hazard. A driver who cannot change gears can lose control of the situation during an emergency, be unable to safely park, reverse, or place the vehicle in neutral if needed. Having to shut the engine off while the transmission is still in Drive is unsafe and not how the vehicle is intended to operate. This issue first occurred around 45,000 miles while the vehicle was under warranty, but it temporarily resolved on its own. It has now returned in June 2026 at approximately 65,500 miles, after the warranty expired, and is happening repeatedly. After researching online, I found many Hyundai owners reporting the same “Shifter System Malfunction” with identical symptoms, indicating this may be a widespread defect. I request that NHTSA investigate this issue, as it poses a serious risk to driver and public safety.

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. Some 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.

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.

Certain 2021 – 2023 model year Santa Fe, 2021 – 2023 model year Santa Fe Hybrid, and 2022 – 2023 model year Santa Fe Plug-In Hybrid vehicles may experience an inoperable horn that may be caused by foreign substances causing internal parts to oxidize. At Hyundai, we are committed to providing vehicles of outstanding quality and value. In an effort to meet this commitment, the warranty coverage for the horn assemblies under these conditions has been extended to 10 years/ 120,000 miles from the date of original retail delivery or date of first use (whichever occurs first) and is valid for original and subsequent owners.

Some Santa Cruz (NXT), Santa Fe (TMA, MX5A), and Sonata (DN8A) models may require replacement of the 8-speed wet dual clutch transmission (8WDCT) when the vehicle sets one of the high pressure electric oil pump (HP EOP) DTCs listed below. This bulletin provides instructions to replace the 8WDCT.
