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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

I am submitting this report to document a serious and dangerous safety defect involving my Genesis G70. Note - Your system pulls my VIN as a G80, I own a G70. On two separate occasions, the vehicle applied braking without driver input and abruptly veered to the left, despite there being no obstacles, vehicles, or road hazards present. During the first incident, the vehicle was operating in Comfort mode with Lane Assist enabled. During the second incident, the vehicle was operating in Sport mode with Lane Assist disabled. In both cases, the braking felt as though it was applied to the front-left wheel, causing an immediate and forceful deviation of the vehicle to the left. Both incidents occurred while the vehicle was traveling at speed and required immediate corrective action. I was forced to divert the vehicle onto the shoulder to avoid a potential collision. My family was present in the vehicle at the time. Had there been a vehicle in the adjacent left lane during either event, a collision would have been unavoidable. No warnings, alerts, or visual indicators were displayed prior to or during either incident EXCEPT late / after or during about Checking Lane Safety Warning There were no objects, lane intrusions, or traffic conditions that would justify autonomous braking or steering intervention. I am reporting this issue as a critical safety defect that poses a serious risk of collision, injury, or fatality. I am also reporting the issue to my authorized dealer, Global Auto Mall (Route 22, North Plainfield, NJ), for immediate inspection and diagnosis. I am aware of other similar reports involving this behavior and believe this issue warrants investigation. I am submitting this complaint to the National Highway Traffic Safety Administration to document the defect and to help prevent potential injury or loss of life.

Car less than 1 month old with approx 500 miles caught fire from the engine and was totaled. Nearly took the driver and house with it.

My oil light kept flashing on while driving until I come to complete stop. Had to take it to Genesis dealership in [XXX] Ms. They did a check on my vehicle and found the problem. I had to pay to replace these issues the sender assy-oil pressure & the harness-op sensor. The total bill was $1,012.14.

Oil tank sensor

Oil pressure light started to come on at idle, goes away while driving.. heard this has been and issue and even the dealership knows about it.. there is also a recall in Korea for the same exact thing for the same exact cars but no recall in the usa..please make this a recall it is not safe nor should this be over looked

While driving the engine simply stops and won't restart. When this happens, the key fob won't lock the car or unlock the trunk. The trunk opening button won't open the trunk. It just flashes the parking light and gives a sound.

At 63,230 miles the engine oil pressure light would illuminate on my 2017 Genesis G80. I took it to the dealer and the technician found the oil pressure switch on my car went bad and in the words of the mechanic was leaking internally. This is a known issue by Genesis/Hyundai as they are performing repairs in Korea (where this vehicle is built and assembled) for this very problem. But in America they are refusing to honor the warranty which under powertrain is valid for 10 years/100,000 miles. Proper function of the engine is clearly a part of the powertrain. The warranty further goes on to state that under engine, "gaskets and seals" are covered. The repairs I had to have performed at great expense for a failed oil pressure switch seemed clear to me under the warranty. Not only a known issue and covered where the car is made, but they seem to know they have a huge issue based on Genesis Forums and their complaints the numbers are large; they don't want to have to make it right for the owners.

The cars engine shut down while driving. Once we got it stopped we put it in park and the car started and we drove it 30 minutes home.

Subject: Safety Concern Regarding 2017 Genesis G80 Dear NHTSA, I am writing to report an ongoing issue with my 2017 Genesis G80. While driving, I have experienced a significant safety concern related to the vehicle's acceleration. Specifically, when accelerating at various speeds, the vehicle begins to jerk abruptly and violently, causing a potentially dangerous situation on the road. After seeking advice, I was informed that the problem might be related to the engine malfunctioning or failing. I am deeply concerned about the safety risks this poses, both for myself and others on the road. I would greatly appreciate any guidance or investigation into this matter to ensure the issue is addressed promptly. Thank you for your attention to this serious safety concern. Sincerely,
 [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The hyundai genesis and the genesis G80 have an oil pressure sensor defect. Practically, everyone i know with a genesis, in particular the 3.8 L engine, has this issue. The oil pressure sensor illuminates even though the engine oil level is fine and this issue can occur at any time regardless of mileage. I'd be surprised if this issue has not been reported to you all.

I want to file a complaint regarding the recall issued for my car. I am concerned that Genesis has not issued a resolution at all and suggests parking the car. If it's unsafe and could ignite itself on fire, a remedy should be issued immediately. Offer us a different model and year or fix the issue. This is people's lives at stake.
