This complaint is filed regarding an under-hood thermal fire incident and unauthorized modification involving a federally mandated safety recall for a 2018 Genesis G80 (VIN: [[redacted]]). To resolve a starting issue, technicians at Van Hyundai in [[redacted]], bypassed the standard ignition circuit and installed an un-fused manual starter bypass switch kit. This bypass directly conflicted with active NHTSA Safety Recall Campaign 24V107000, which requires a specific fused relay kit (Part 91950-DH15KQQH) to...

Failing oil pressure sensor which "blinds" the driver of the engines true oil levels. It occasionally causes the car to go into "limp" mode or stall which could cause unnecessary and unreasonable traffic safety hazards. This is a well known and documented critical safety defect by Genesis as they've already executed a recall for the issue in their home country / market of South Korea.

When negotiating a curve, the steering wheel sticks and does not return to center without the driver forcing the wheel back to the required direction. Instead of a smooth and consistent feeling when turning the wheel, the steering wheel feels "locked" until the driver's force breaks the steering wheel free. In addition, the steering wheel makes a faint but noticeable grinding noise when turned in either direction. No warning lights illuminate.

After 2 hours on the road August 1, 2026 (from [[redacted]] to [[redacted]]), in 119-degree heat, the AC stopped blowing cold air out of the dash vents. There was cold air coming out of the rear-seat vent. The vehicle became unbearably hot. (Took my wife 2 days to recover from heat exhaustion.) The AC started working properly after the car sat for a few days in [[redacted]]. The Genesis Escondido service shop has not been able to duplicate the problem. The vehicle is still there at the shop. Genesis Customer Care...

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...

Driver side rear door electric latch is stop working and i tried to open the latch manually but the locked latch won't let me but remain locked.

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...

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...

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...

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.

I hit a grass wall after striking a deer who bent my control arm and all airbags DEPLOYED BUT THE ONE WHO SAVES THE DRIVER THE MOST IMPORTANT AIRBAG

1-The steering wheel airbag failed to deploy during a collisiom while all other airbags `airbags including rear seat airbags -did deploy. This suggest a possible malfunction in the airbag control module steering wheel airbag unit or sensor system. **Yes the vechcle is available for inspection by genesis, nhtsa, or any authorized party. 2. As the driver I was at direct risk the steering wheel airbag is designed to protect the head and chest in a frontal collision. Its failure to deploy left me vulnerable to...

A/C does not work as blower will not put out cold air. During hot days in Florida with children and elderly in the car this poses a risk to our health. This happens when A/C has been on for approximately one hour. No warning messages whatsoever. This has been reported by many Genesis G80 owners who own a G80 from the years 2017 - 2020. Genesis Corporate is aware of the problem but has not submitted a recall.

Oil pressure sensor issues.

Component: Engine / Turbocharger / Oil Line / Fire Risk Vehicle Problem: For the past five months, my oil light has been coming on and off sporadically (not flickering), even though mechanics and oil shops said there was no issue. A few days ago, the car started smoking out of nowhere, though it wasn't overheating and there were no visible signs of leakage. I took it to the shop, and they diagnosed a turbocharger oil supply pipe leak that is severe and poses a fire risk. I am in a new city with no support system...

Rear left door lock actuator has failed. Door will not open from inside or outside. There is no emergency release of any kind. This is a major safety concern as in the event of an accident occupants could be stuck inside the vehicle. This is a known issue with this model as well as several Hyundai/Kia models

Engine while driving inadvertently stalls and vehicle shuts off. Does not matter what the conditions are. Have to place vehicle back in park and completely shut down vehicle to restart. It first starts by engine slowing down and then engine speeding up and ultimately stopping. When placed in park vehicle lungs forward slightly and front sensor tends to go off in warning without a vehicle in front of

My 2018 Genesis G80 has an issue in which the A/C quits working and blows warm air on the driver's side. I live in Florida where the heat is stifling and having warm air blowing during the high temperatures is dangerous. I have contacted Genesis who sent me a $220 Gift Card to have the dealer diagnose the problem. The dealer stated that this is a very common problem that Genesis will not acknowledge. My car only has 28,385 miles on it and is stored in a garage most of the time. I was told it needs a new...

Reverse lights no longer illuminate when placing car into reverse. This is a safety issue as cars behind me are not made aware if I am wanting to reverse until they see the car in motion.
