Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
While accelerating to highway speeds, the vehicle suddenly experienced a significant and continuous loss of power. Even with the accelerator fully pressed, the vehicle would not increase speed beyond roughly 50 mph. Based on the behavior and previous service history, the issue appears to be related to the engine, fuel delivery system, or overall powertrain. The incident created a serious safety concern for both the occupants and surrounding traffic. The vehicle could not properly accelerate, merge, or respond to normal highway conditions. Hazard lights had to be activated, and the vehicle remained in the slow lane for an extended period to avoid faster-moving traffic. The issue was consistent and repeatable throughout the drive. Multiple attempts to accelerate resulted in the same lack of response, and the loss of power persisted for the duration of the trip. The vehicle has not yet been inspected following this occurrence because when turned off and turned back on, the issue goes away and happens sporadically. It is also worth noting that the vehicle previously underwent a manufacturer-covered repair involving the high-pressure fuel pump, for which a warranty extension had been issued. This loss of power occurred after that repair was completed. No warning lights, alerts, or prior symptoms were present before or during the incident. Overall, the sudden loss of propulsion at highway speed posed an immediate safety risk, as the vehicle was unable to maintain appropriate speed or safely maneuver with traffic.
While driving at highway speed, the vehicle experienced a sustained loss of motive power. Despite the accelerator pedal being fully depressed, the vehicle would not accelerate beyond approximately 62 mph. Based on the symptoms and prior service history, the malfunction appears related to the fuel/propulsion system, engine, or powertrain. The vehicle is currently parked and available for inspection upon request. This failure placed the safety of the occupants and other motorists at risk. The vehicle was unable to safely accelerate, merge, pass, or respond to traffic conditions. Hazard lights were activated, and the vehicle was forced to remain in the slow lane of the highway for an extended period to avoid being struck by faster-moving traffic. The problem was reproducible and occurred repeatedly during the same trip. Acceleration was tested multiple times, and each attempt resulted in the same loss of power with no response to throttle input. The condition persisted for the entire drive. The vehicle has not yet been inspected following this incident. However, the vehicle previously received a manufacturer warranty repair involving replacement of the high-pressure fuel pump, and the manufacturer has issued a warranty extension for this component. The loss of motive power occurred after that repair. No warning lamps, alerts, or messages were observed prior to or during the failure. There were no warning symptoms immediately preceding the loss of motive power. This loss of propulsion at highway speed created a serious and immediate safety hazard due to the inability to maintain normal traffic speed or maneuver safely.

The car randomly goes into LIMP mode when driving in every condition going at any speed, the car has a significant loss of power and needs to be restarted to gain power back. I have almost crashed because of this problem numerous times. Genesis dealership refuses to fix anything because the car doesn't bring back any error codes. This has happened to new and older G70s, there has also been numerous LEMON LAW buy packs under this exact LIMP mode issue being way more prevalent. I have gotten the supposed "fuel pump" recall which is what is directly affecting this issue and the problem persists. Genesis is aware of the issue and extended the dual pump warranty extensively. My car is extremely unsafe at random intervals during my daily commute. This issue is extremely dangerous and could cause a horrific crash. The car basically turns into a slug even when flooring the pedal to try and speed up, this makes merging and changing lanes on these New York highways extremely dangerous. There is an inherent problem with the design of this car in terms of how the fuel pump and fuel pump sensors operate. Genesis is aware of the issue and does nothing to fix it because wait for catastrophic failure of a competent and worse a crash that could result in a fatality.
Dealer did not complete recall while in service Nov 15 2024, service order shows parts are on back order. After 2 months I reached out to Corp who reached out to dealer. Both copr and the dealer ended up calling back just yesterday, however the message from copr stated the part is ordered it's way but the message from the dealer stated software upgrade needs to be done first before ordering parts. But why software upgrade was never done 2 months ago while performing service? I can smell excess gasoline 5 mins after remote started and my thermometer temp spikes significantly upon start. Car has only 12k miles. I am afraid car is going to burn down and they will do everything possible to avoid repair/replacement. I'm hoping this would create a record of historical events as well as poor service performance by the dealer.

There is a constant wheel bearing-type noise that is distractingly audible above ~40mph, and the whine is load and annoying at ~80mph, coming from the rear of the car. There is a constant droning and harmonic pulsating noise that cannot be attenuated with the car's active noise suppression technology, either. It is an otherwise wonderful car, but this whining is going to become more of an issue now that summer is here and the windows will be down. The pitch of the whine increases in frequency as the road speed increases, and right/left steering movements or accelerate/de-accelerate activities don't seem to affect the intensity of the rearend bearing noise. The ever-present noise (our mileage of just over 25k) has grown over the last ~5k miles to be rather unpleasant inside of the cabin, and our current scheduled maintenance visit did not produce a solution for the ever-present noise.

Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
The vehicle experienced a sudden emergency braking intervention on the highway. Alert came on and it said emergency breaking with curved red arrow and the car slowed down from around 70mph-60mph. Lane assist was on but the car was not on cruise control. The problem was resolved after pressing the accelerator. I was not hit but the could have been a dangerous situation if someone was right behind me.
While driving my Genesis G70 on the highway in rainy conditions, the vehicle repeatedly loses traction and hydroplanes at normal highway speeds. The car begins sliding across lanes with very little control. During a prior incident, driver-assist features (lane keeping assist) were active. Rain appeared to interfere with the sensors, and the system malfunctioned by steering incorrectly. The steering wheel became difficult to control, and the vehicle attempted to steer into another lane while traction was already compromised. The vehicle hydroplaned across multiple lanes of the expressway, creating a high risk of collision. The system’s steering input did not match driver intent and made the situation more dangerous. The vehicle ultimately came to a stop near a wall but avoided impact. After this incident, I turned off the lane keeping assist feature. However, the problem continues. On a separate occasion, while entering the highway in rainy conditions, the vehicle immediately began sliding again, indicating an ongoing traction or stability issue even without driver-assist features active. This issue has occurred more than once and creates a serious safety risk to myself and others, as the vehicle becomes difficult to control and does not maintain proper traction in wet conditions.

Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
The contact owns a 2023 Genesis G70. The contact stated that while driving on several occasions at various speeds, the "Turn Signal Error" message was displayed and an orange master warning light was illuminated. The vehicle was taken to the residence, where the contact noticed condensation in the passenger’s side headlight. The contact stated that the passenger’s side turn signal bulb was replaced. The vehicle was then taken to a dealer, and it was determined that the passenger’s side headlight was damaged by an object. The vehicle was not repaired. The insurance company was informed of the issue and notified the contact that the issues were related to common stress factors. The vehicle was then taken to an auto body shop, where it was determined that the seals of the passenger’s side headlight had cracks or holes, causing condensation and water to enter the headlight assembly. The vehicle was not repaired. The contact stated that a week later, the driver's side headlight had a similar failure. The vehicle was taken to a dealer, where it was determined that an impact might have caused the failure. The vehicle was not repaired. The manufacturer was notified of the failure, and a claim was submitted. The failure mileage was approximately 52,000.
The headlights somehow gets condensation/moisture inside of them and when this happens it makes the turning signal faulty and not work properly. A notification pops up in the vehicle that says “check turn signal” and the turing signal does not flash properly. This has happened to my vehicle and I am part of a Facebook group and many of us G70 owners are having the same issue. The dealerships are claiming something cracked the headlights, letting moisture in. But the headlights are not cracked at all and there are an abundant amount of G70 owners having the exact same issue that is very expensive to fix. Some are even paying to get it fixed and still having the same issue after. This should be recalled to make it right and safe for drivers.

Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
Unintentional acceleration - parked car crashed into garage wall, damaging front bumper and home structure. Have lost all faith in vehicle. Sensors and automatic brake failed. Car concerns have been reported and waiting 6-8 weeks for GMA to deem if it is eligible for an investigation. No loaner car offered despite being told NOT to drive the vehicle. No prior warnings. No one was home to drive the car. Very concerning.
