SERVICE BRAKES

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.

WHEELS

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

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.

ENGINE

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.

POWER TRAIN

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.

ENGINE

The fuel delivery system, specifically the fuel pump and fuel rail pressure system, has malfunctioned and continues to trigger diagnostic trouble code P0191 (fuel rail pressure sensor range/performance), despite a prior recall-related software update performed by the dealer, and the vehicle and all affected components are available for inspection upon request. While driving on the highway, the vehicle suddenly began stalling, hesitating, and hard jerking before losing power and entering limp mode, limiting speed to under 50 mph and forcing me to immediately pull over, which created a serious safety risk to myself and other drivers due to the sudden inability to maintain highway speeds. The issue has been confirmed by an authorized dealer through repeated diagnostic scans showing the same fuel system fault codes, and the dealer has determined the fuel pump now requires replacement, indicating the recall update did not resolve the underlying failure. The vehicle has been inspected by the dealer on behalf of the manufacturer, and prior to the failure the check engine light illuminated and has remained on since, with symptoms escalating abruptly and occurring without warning, making this an ongoing and unpredictable safety issue.

FUEL/PROPULSION SYSTEM

I was driving on major highway around 66.mph and the car lost acceleration and dropped to 45.mph quickly and It wouldn't accelerate when I hit gas pedal. I was almost rearended om highway because of this. I quickly pulled onto shoulder. Car is currently under manufacturer warranty and being assessed by dealership. It did generate a code P0190 upon scan. However, dealership cannot get it to replicate at this time. Pending information from dealership. My car did.not fall under first recall for fuel.pump issue but it should now. See code below.

EXTERIOR LIGHTING

HEADLIGHTS WITH LOTS OF CONDENSATION. APPARENTLY GENESIS HAS BEEN HAVING ISSUES WITH THEIR HEADLIGHTS. THIS IS A SAFETY ISSUE ESPECIALLY AT NIGHT. HEADLIGHTS GOING OUT DURING THE DAY IS A MINOR CONCERN BUT CAUSING MORE ELECTRICAL ISSUE IN THE VEHICLE IS A MAJOR CONCERN, ALONG WITH HEADLIGHTS GOING OUT AT NIGHT. THERE SHOULD BE A SAFETY RECALL FOR GENESIS HEADLIGHTS.

POWER TRAIN

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.

ELECTRICAL SYSTEM

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.
