ELECTRICAL SYSTEM, STRUCTURE:BODY
The windows do not roll down or up from any of the switches. this was taken in for a warranty repair and after i received the vehicle back. it worked for a day and has now began to do the same intermittent working and not working. where more often than not i am unable to roll the windows down. Along with the memory seat function not recognizing any presses. On vehicle pickup, the memory seat function was not working, the technician immediately hooked his tools up and reset something and got it working again. They said they had replaced a harness to get the door switches working properly. However the same issue has not started again. leading me to believe that was not the cause of the issue. Like before trying to roll the windows down from either the drivers master switch or any of the passenger door switches results in no operation conditions. randomly it will start working for a bit but than go back to inoperable. This problem has been occurring since i got the car and will be calling the dealer back again to express the dissatisfaction and failure to repair what they claimed to have fixed. It has already spent just under 2 months in the shop out of the 3 months that i have owned the vehicle.

SERVICE BRAKES, ELECTRICAL SYSTEM, STEERING
This is a follow-up to complaint #11714226 regarding an ongoing safety defect. The defect has now resulted in a crash. The vehicle experiences repeated unintended braking at highway speeds (50–79 mph) without driver input and with no obstacles present. During multiple events, the steering becomes temporarily unresponsive or “locked,” preventing driver control. The vehicle has also exhibited unintended lane departures, erratic lane changes, and unexpected acceleration following braking. Warning indicators including Forward Collision-Avoidance Assist, Automatic Emergency Braking, Driver Attention Warning, Lane Assist, and Master Warning have illuminated without cause. This vehicle has been presented three times for repair attempts specifically for these braking and steering systems and has been out of service over 30 cumulative days. The manufacturer was unable to duplicate or repair the defect and returned the vehicle unrepaired. On March 12, 2026, Genesis Corporate (Case Manager Terrence) stated they were coordinating with Genesis of Selma to schedule a fourth repair attempt. However, on March 26, 2026, Mike at Selma Genesis stated via text: “We as a dealer won’t be working on your car.” This directly contradicts Genesis Corporate and has prevented further repair attempts. On [XXX], while traveling approximately 55 mph, the vehicle experienced a sudden loss of steering control combined with unintended braking, causing it to leave the roadway and collide with pistachio trees. Law enforcement responded. I sustained back and neck pain and sought medical care. The defect remains unresolved and poses a serious risk of injury or death.

UNKNOWN OR OTHER
The car was purchased on [XXX]. On [XXX]—only six days after purchasing the car—it failed to accelerate through an intersection while turning left in front of oncoming cars. Less than a week later, on [XXX], the car again failed to accelerate as it slowed down entering a rotary on [XXX] . The same thing happened again on [XXX] as it was driven out of the Savannah Bend Marina, turning left onto [XXX] , and yet again on [XXX] while driving around a traffic circle on [XXX] . On [XXX], the car once again failed to accelerate when attempting to clear an intersection on [XXX] Pooler, a Savannah suburb. On [XXX], after starting the car in the garage, it obviously had a problem running while idling. Backing out of the carport and pulling out onto the street, it barely responded. Even after the accelerator was practically floored, the car would go only about 35 miles per hour. On [XXX], the car yet again delayed in accelerating while turning left onto [XXX] from [XXX] . As it turned left and the accelerator was pressed down, the car slowly inched forward for a few seconds before finally accelerating and clearing the intersection, barely averting a collision with oncoming traffic. The dealership has had multiple attempts to repair the defect, but it has been unable to locate or remedy the defect.

WHEELS
Description of Incident: The car was sold with a passenger-front Dunlop tire that suffered a critical structural failure where the tread rubber completely wore away, leaving the internal metal cords and plies exposed (visual evidence attached). I was unknowingly operating the vehicle in this hazardous condition for 136 miles of highway and local driving until the defect was fully identified on February 14th. Component Availability: The tire was removed from the vehicle on February 14th by an independent service center during the emergency purchase of four new tires. While the physical tire was left for disposal at the service center, high-resolution photographs of the failure are available and attached to this report for inspection. Safety Risk: The vehicle was sold in an unsafe and illegal condition (IL Vehicle Code 625 ILCS 5/12-405). The exposed structural metal plies created an imminent risk of a high-speed blowout or catastrophic tread separation, endangering both the occupants of my vehicle and other motorists. Confirmation/Inspection: The problem was confirmed by a certified technician at an independent service center on February 14th, who identified the tire as unfit for service. The selling dealer (Jidd Motors) was notified of a defect on February 6th but refused to replace the tire. This incident has also been reported to the Illinois Attorney General and the Illinois Secretary of State Police (Dealer Operations). Warning Symptoms: There were no warning lamps, TPMS messages, or symptoms prior to the physical discovery of the exposed metal. The tire maintained air pressure despite the severe structural compromise.

AIR BAGS
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 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.

AIR BAGS, UNKNOWN OR OTHER
⭐ 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.

EXTERIOR LIGHTING
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.

SERVICE BRAKES, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving at highway speeds (55–73 mph), the vehicle has repeatedly and unexpectedly applied the brakes on its own and on at least one occasion experienced a loss of power. These events occurred without any vehicles, pedestrians, or obstacles present, and without any driver input. Road and weather conditions did not warrant braking. On multiple occasions, the vehicle suddenly decelerated while adaptive cruise control was engaged, then immediately re-accelerated back to the set speed. This created a serious risk of being rear-ended or involved in a high-speed collision. On one occasion, the vehicle experienced a loss of power while driving at highway speed, requiring immediate driver intervention to avoid a dangerous situation. These incidents make the vehicle feel unpredictable and unsafe to operate as intended. I regularly transport family members, and these failures place my safety and the safety of others at significant risk of serious injury or death. The vehicle has been inspected by an authorized Genesis dealership on two separate occasions. Despite extended road testing, the dealership has stated they were unable to reproduce the issue and no permanent repair has been performed. The manufacturer has been notified, and the defect remains unresolved. No warning lights or messages were present prior to the incidents. The failures occur suddenly and without advance indication.

POWER TRAIN
When turning on the car, the right side of the dashboard (digital panel) will not turn on, it will not display rpm, gas or speed. The turn signals are not making the click noise. The issue happens randomly and I haven’t been able to replicate it in the presence of the dealer. Once the dashboard is back on the service engine light will come on and a service code is noted on the diagnostic system. This has been ongoing since the car was brand new, the first instance at 1,200 miles

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

AIR BAGS
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.

AIR BAGS, ELECTRICAL SYSTEM, STEERING
I am writing to formally report a serious safety defect in my Genesis vehicle and to request immediate investigation, documentation, and corrective action. Following a recent crash event, my vehicle’s diagnostic scan revealed DTC B1378, which is associated with a fault in the airbag system circuitry. This code is widely recognized as an indicator of an airbag defect and is consistent with conditions that warrant manufacturer recall. During the crash: - Multiple airbags deployed, - The steering‑wheel airbag did NOT deploy, - The SRS system recorded a crash severe enough to trigger other airbags, - The vehicle now displays B1378, confirming an internal fault. The failure of the primary driver airbag to deploy during a crash is a critical safety malfunction. Combined with the presence of B1378, this raises substantial concerns regarding a defective airbag module, wiring harness, or sensor — all of which fall under manufacturer responsibility and federal safety standards. I am requesting the following: Immediate corrective action, including repair or replacement of all defective components. Documentation of this issue in your internal safety‑defect tracking system. Given the severity of this failure and its implications for driver safety, I am also submitting this information to the National Highway Traffic Safety Administration (NHTSA) for review. Please confirm receipt of this letter and provide a written response outlining the next steps. Sincerely, [XXX] Hagerstown, MD --- INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM
There is a known issue with these vehicles where the Oil Pressure Sensor/Switch triggers at idle and low RPMs but nothing is necessarily wrong other than the sensor itself. However, since the sensor malfunctions, owners can’t know if the pressure is actually bad or if oil levels are normal. This is a safety concern for all owners. However, Genesis is requiring owners to pay around $3000 to repair this. Most of the models are 2017-2019, which are past its manufacturer warranty years.
