My car was diagnosed with burnt wiring causing the Complete front wiring harness needing replaced. The Company Genesis don’t want to repair/fix the problem or the Warranty company. The Service Manager Mr. Daryl has said this is a manufacturing defect issue. They have repaired several on this particular vehicle and somebody should cover it. If anything happens to me, I am suing or my Family will. Burnt wiring can cause a fire.
NHTSA complaint #11757190 — an unverified report by a vehicle owner.
My 2017 Genesis G80 3.8L, VIN [XXX], has approximately 43,840 miles and intermittently slips or shifts improperly between approximately third and fifth gears while driving and causes harsh jolts forward. Jenkins Genesis confirmed the condition, stated that the transmission was slipping from the 3–5 clutch area, and recommended complete transmission replacement. The malfunction is unpredictable and creates a risk of sudden loss or interruption of propulsion while merging, crossing an intersection, changing lanes or driving at highway speed. A driver may press the accelerator but not receive the expected forward power. A [XXX] infant is regularly transported in the vehicle. The vehicle also has a faulty right-front ABS wheel-speed sensor, a passenger seat-belt safety-system communication fault, and intermittent electrical or sensor warnings. Genesis TSB 21-AT-010HG-1 applies specifically to the 2017 G80 and addresses shift flare or harsh shifting during the 2–3, 3–4 and 4–5 shifts. It requires transmission-solenoid, wiring-harness and fluid inspection procedures. TSB 19-AT-014HG also addresses harsh or delayed shifting in 2017–2018 G80 vehicles and provides electronic shift-data testing. The written repair estimate does not establish whether all applicable TSB diagnostic procedures were completed. The model also has electrical recall history, including NHTSA recalls 24V-107 and 21V-161. I am not claiming the recalls caused the transmission failure, but the concurrent transmission, ABS, seat-belt and electrical faults warrant investigation. I request that NHTSA examine similar G80 complaints involving slipping, shift flare, delayed shifting and loss of propulsion.

WHEN YOU PRESS ON THE GAS ACCELERATOR- THE CAR ONLY MOVES AT A FEW MILES PER HOUR. THIS IS INTERMITTENT BUT MAKES THE CAR UNDRIVEABLE AND VERY DANGEROUS TO DRIVE IN TRAFFIC. THE THROTTLE BODY WAS REPLACED BUT NOW GENEIS SAYS IT IS ANOTHER ELECTRICAL ISSUE AND THE CAR NEEDS A NEW HARNESS- BUT GENSIS NO LONGER MAKES THIS PART (THE HARNESS) SO GENESIS EVEN UNDER MY WARRANTY CANNOT FIX THE CAR GENESIS SAYS IT IS A HARNESS ISSUE AND THEY DON'T HAVE AND CANNOT GET THE PART- HENCE THEY CANNOT FIX THE CAR

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.

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.

NHTSA complaint #11730299 — an unverified report by a vehicle owner.
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.

NHTSA complaint #11710394 — an unverified report by a vehicle owner.
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.

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 IMPACT WITH THE STEERING WHEEL AND DASHBOARD. THE LACK OF DEPLOYMENT HAS WORSED THE OUTCOME 3. NOT YET I AM SEEKING A DIAGNOSTIC SCAN FROM GENESIS - CERTIFIED DEALER TO CONFIRM THE FAILURE AND IDENTIFY ANY FAULT CODES IN THE AIRBAG SYSTEM. 4. THE VEHICLE IS BEING ASSIGNED TO AN AJUSTER BUT NOT YET BY GENESIS OR NHTSA. I AM REQUESTING A FORMAL INSPECTION BY GENESIS AND WILL PROVIDE ACCESS TO THE VEHICLE. 5. THERE WAS NO WARNING LIGHTS OR MESSAGES PRIOR TO THE INCIDENT. 6. I WAS NAVIGATING A TURN WHEN A DEER ENTERED THE ROADWAY I SWERVED AND THE FRONT RIGHT WHEEL BECAME STRUCK CAUSING ME TO STRIKE AN EMBANKMENT. THE CONTROL ARM BROKE AND THE IMPACT TRIGGERED FULL AIRBAG DEPLOYMENT INCLUDING REAR SEAT AIRBAGS BUT NOT THE STEERING WHEEL AIRBAG Based on the severity and location of the impact, the steering wheel airbag should have deployed. I believe this failure may be due to a sensor malfunction or defect in the airbag system. This raises concerns regarding the reliability of the vehicle’s safety mechanisms, as the absence of steering wheel airbag deployment during such a significant frontal impact posed a serious risk to driver safety.

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.

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

The AC system on this car, and seems series of years is widely known to have major issue, as is the case with mine. I'm having issues with the dealer telling me the car is out of warranty 35k miles, 2019 year. Based on researching and talking with other owners they are also having similar issues, AC not cooling well, hot on some vents, works for a time period then stops, etc.
NHTSA complaint #11669207 — an unverified report by a vehicle owner.
The entire instrument panel/cluster went out while driving. It did come back on after going totally black. We had no ability to see speed, fuel, or any cameras. This happened yesterday, May 13, 2025. We are trying to get an appointment at the dealership to address it. There does not appear to be any error codes recorded by the vehicle for this event, according to the app. It appears that this problem is the same as an existing recall for G80 vehicles through 2024. Genesis and NHTSA needs to add 2025 models to this recall (026G)

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.
NHTSA complaint #11645647 — an unverified report by a vehicle owner.
Oil light keeps coming on suddenly, I looked online and there are many people who have had the same issue. It's only intermittent, and turns off when moving and turns on when idle. The first time it came on was when I was crawling on a first time in forever frozen Alabama road. I was very careful not to start sliding, and when the sign came on I panicked and ended up in a ditch. The safety issue comes from not knowing if this is a sensor issue or an actual oil issue. Most people stated that it was a sensor issue but to replace it, you must access inside of the motor.

There are two safety recalls, one for the starter and one for the turbo oil supply line, both have potential for a fire concern and the manufacturer has failed or is unable to remedy this safety recall for my vehicle in a timely manner.
NHTSA complaint #11628603 — an unverified report by a vehicle owner.
For over one year we have been in contact with Round Rock Genesis in Round Rock, Texas about recalls # 254 & 018G (NHTSA Recall # 24V107000). Our Genesis G80 is now 6 years old. Failure to address this repair poses a risk of the car bursting into flames with no warning; Genesis advises parking the car outside. These recalls have not been performed because the dealership claims that they cannot get the needed parts. Recalls # 201 and 006G are meant to address the anti-lock braking system. Failure to address these recalls poses a risk of brake failure and fire. Because the service department of Round Rock Genesis have failed to ever call us back despite many messages left for them, we are not sure if this is still a current recall on this vehicle.

Whenever I drive long distance like 1 or more hours, AC has problem. It worksd fine in short local distance. I see a lot of drivers have the same issue if you click the link below. During the hottest season, it can become very dangerous. I live in San Angelo, TX, and there is no Genesis dealership in here. Hyundae dealership couldn't figure it out. The nearest Genesis dealership takes 3 hours from my house. I paid for extended warranty which will expire within 4 months, and its useless unless it can get fixed. [XXX] (It's not a easy fix to Genesis service.) Please help me to resolvbe the issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
