Most Recent Complaints
The contact owns a 2018 Genesis G80. The contact stated that while driving at an undisclosed speed, the contact's vehicle was involved in a crash. The contact stated that the vehicle crashed into a deer, and then crashed into a hill. The vehicle spun around three times and rolled over after crashing into the hill. The front driver's air bag did not deploy. The contact stated that no warning lights were illuminated. A Police report was filed. The contact sustained bruises to the chest and back pain. The passenger who was seated in the front passenger's seat sustained bruises. No medical treatment was provided at the scene of the crash, however the contact later visited her primary physician. 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.
⭐ 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.

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.
I WAS IN A ACCIDENT SEVERE ENOUGH TO DEPLOY ALL AIR BAGS BUT MY STEERING WHEEL, I WENT TO GENESIS WITH THE ISSUE AND THEY INSPECTED THE CAR WHEN THEY EDR REPORT CAME BACK EVERYTHING MATCHED BUT THE MODEL OF THE CAR IT COMES BACK TO A GV80, ON MY GENESIS APP MY CAR COMES BACK AS A G90, MY CAR IS A GENESIS G80 THE MATTER CONCERNS CONFLICTING VEHICLE INDETIFACTION DATA ACROSS MULTIPLE OFFICIAL GENESIS SYSTEMS AS WELL AS A FAILURE OF THE AIRBAG TO DEPLOY DURING A CRASH. TWO IDENPENDENT GENESIS SYSTEMS - THE EVENT DATA RECORDER EDR AND THE OFFICIAL GENESIS OWNER PORTAL ARE IDENTIFYING MY VEHICLE AS A DIFFERENT MODEL A GENESIS GV80 AND G90 DESPITE MY CAR BEING A G80. THESE SYSTEMS SHOULD NEVER DISAGREE ABOUT THE VEHICLES IDENTITY AS THEY ARE RESPONSIBLE FOR SAFETY CRITICAL INFORMATION CRASH DATA WARRANTY TRACKING AND RECALL ELIGIBILITY.. THE EDR BOX SHOWING THE INCORRECT MODEL IDENTIFACTION .. THIS IS A MAJOR DEFECT DATA MISCLASSIFICATION AND A SAFETY SYSTEM FAILURE THAT CALLS FOR A RECALL
