2018 Genesis G80

The Office of Defects Investigation (ODI) has received eight Hyundai Motor America (Hyundai) and eight Kia America, Inc. (Kia) Part 573 Recall Reports between 2016 and 2023. The combined 16 safety recalls all involve the antilock braking system (ABS) modules or Hydraulic Electronic Control Units (HECU) manufactured by the equipment supplier Mando. The Part 573 Recall Reports contain varying defect descriptions and differing remedy descriptions for the same or similar equipment supplied by Mando. Safety recalls included in this Audit Query (AQ) review include: Hyundai recalls 20V-520, 20V-543, 21V-161, 21V-160, 21V-303, 22V-056, 22V-810, and 23V-651. Kia recalls 16V-815, 20V-518, 20V-519, 21V-137, 21V-331, 22V-051, 22V-800, and 23V-652 The purpose of this AQ is to evaluate the timeliness and scoping of Hyundai and Kia’s defect decision making and adherence with reporting requirements; and understand the varying defect descriptions and remedies between these recalls.

Dear NHTSA Office of Defects Investigation, I am submitting this letter to request an urgent review of a recurring and widespread air‑conditioning failure in the 2018 Genesis G80. The AC system consistently shuts off after extended driving and does not cool down when the car starts, especially in high‑heat environments In Texas, cabin temperatures can exceed 120°F, creating conditions that can lead to heat exhaustion or heat‑related illness. This is not an isolated incident. Many owners have reported identical symptoms: AC cooling stops after prolonged operation, airflow continues but without cooling, and the system only resets or thaws after the vehicle sits for an extended period. Despite these repeated complaints, no investigation or recall has been initiated. While AC failure is typically categorized as a comfort issue, the extreme heat exposure caused by this defect presents a legitimate safety concern. Occupants may become ill, visibility can be affected by humidity and fogging, and the failure appears to be tied to HVAC components that may not be functioning as designed.I respectfully request that NHTSA open a defect investigation into this issue to determine whether a safety recall is warranted. Thank you for your time and consideration.

⭐ 1. The Airbag Control Unit (ACU) and associated restraint‑system components appear to have malfunctioned. The Event Data Recorder shows inconsistent airbag deployment staging, a pretensioner firing while the belt was recorded as unbuckled, a seat‑track sensor fault, unsupported occupant‑classification data, incomplete curtain‑airbag deployment during rollover, and missing crash‑event data. Yes, the vehicle and the full 29‑page EDR report are available for inspection upon request. ⭐ 2. The restraint system did not protect the occupants as expected. I suffered chest injuries from hitting the steering wheel, and my passenger sustained injuries to their hand and arm. These injuries occurred because the driver airbag did not deploy correctly, the pretensioner logic was inconsistent, and the curtain airbags did not deploy on the driver side despite multiple full vehicle rotations. The system’s irregular behavior increased the risk of serious injury or death. ⭐ 3. No. The issue occurred during a crash event and cannot be safely reproduced. However, the malfunction is confirmed by the vehicle’s own Event Data Recorder, which documents the deployment irregularities, sensor faults, and data‑integrity issues. ⭐ 4. The vehicle was inspected by insurance representatives after the crash. The manufacturer has not performed an engineering‑level inspection of the Airbag Control Unit or restraint‑system logic. The EDR report was obtained through the insurance process and serves as the primary source documenting the malfunction. ⭐ 5. No warning lamps or messages appeared prior to the crash. There were no symptoms indicating that the airbag or restraint system would malfunction. The failures were only discovered after reviewing the Event Data Recorder.

The vehicle was towed to the contact's family members' residence and later towed to the contact's residence. The insurance inspection confirmed that, according to the EDR, the front diver's air bag skipped stage one. In addition, the contact was informed that an unknown recall had been initiated for the front passenger's air bag for the vehicle. The manufacturer was made aware of the failure but provided no assistance. The contact was informed that the aftermarket seat covers were the cause of the steering wheel's functionality not functioning as intended. The contact was informed that the aftermarket seat cover was the cause of the driver's side air bag not deploying. The contact stated that the seat covers were purchased after the crash to cover the damaged seats as a result of the crash. The failure mileage was approximately 126,000.

When operating the headlights in auto dim mode and the headlights are bright, when I try to dim the headlights manually using the dimmer switch, the headlights go out completely. When operating the headlights with auto dim mode turned off and the headlights are bright, when I try to dim the headlights manually using the dimmer switch, the headlights will not dim. This places myself and oncoming traffic at risk by them either being blinded by the high beams when I'm unable to dim or me hitting them or another object when the lights go out completely when I try to dim them. I reported this to the local dealer who mentioned similar issues on model years prior to mine which were sold under the Hyundai Genesis branding. I will note that the Hyundai Genesis model and my Genesis G80 model use the same platform.....the cars are identical except for the branding. The Hyundai Genesis model referenced had a recall for this issue, so I don't understand why the same recall hasn't been issued for the Genesis G80 model, which is having the same safety issues.

The contact owned a 2018 Genesis G80. The contact stated that while driving at an undisclosed speed during the night, a deer hit the contact's vehicle on the front passenger side. The vehicle spun around and ended up in a "grass hill" where it came to a stop. The driver-side air bags did not deploy. However, the front passenger and side curtain air bags were deployed. The front passenger-side control arm detached from the vehicle due to the impact. The police were called and filed a police report. The contact and the passenger were not injured. The vehicle was towed to the residence. The contact took the vehicle to the dealer. The manufacturer was notified of the failure, and a field inspector from Genesis stopped by the Hyundai dealer to retrieve the Event Data Recorder (EDR). The inspector informed the contact that the Event Data Recorder (EDR) showed that the contact's vehicle was a GV80. The contact stated that her vehicle is a G80. The field inspector then requested permission from the contact to retrieve the information from the Event Data Recorder (EDR) to change the vehicle information to a G80. The contact refused. The contact stated that the Genesis application on the contact's phone provided the following codes: B1378, which meant that the "Side Airbag Front-Driver Resistance is too High," and B1649, which meant "Crash Recorded - Rollover Event." The dealer replaced the control arm. The air bags were still deflated. The vehicle is at the contact's residence. The insurance company was informed. The failure mileage was approximately 127,000.

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.
