2019 Genesis G70 fuel system problems

FUEL/PROPULSION SYSTEM

I own a 2019 Genesis G70 3.3T Twin-Turbo V6, VIN [XXX], with approximately 122,000 miles. Twice within approximately two weeks, the vehicle has suddenly and unexpectedly experienced a near-total loss of propulsion while being driven. Without warning, the engine begins shaking and sputtering severely, the Check Engine Light illuminates, and the vehicle provides almost no usable acceleration. The engine does not completely stall but operates barely above a stalled condition. After safely stopping, turning the vehicle off, and restarting it, normal engine operation and full power immediately return and the Check Engine Light extinguishes. The vehicle may then operate normally for days before the condition occurs again without warning. This creates a serious safety hazard because the failure could occur while traveling at highway speeds, merging, changing lanes, or crossing traffic. A sudden near-total loss of propulsion under those circumstances could result in a serious or fatal collision. I have found reports from other Genesis G70 owners describing substantially similar intermittent loss-of-power conditions that temporarily resolve after an ignition restart. Genesis has also issued safety recalls involving G70 powertrain-related conditions, including NHTSA Campaigns 24V-528 and 24V-191. I have formally notified Genesis Motor America in writing and requested immediate investigation and repair. I am submitting this complaint so NHTSA has an independent record of this recurring and potentially dangerous loss-of-propulsion condition and can determine whether it represents a broader safety defect affecting Genesis G70 vehicles.

FUEL/PROPULSION SYSTEM

Vehicle is currently disabled due to Open Recall Campaign #262/023G (NHTSA Recall Number 24V528000) for High-Pressure Fuel Pump Failure. On 05/19/2026, the vehicle suffered total loss of drive power at highway speeds (Hwy 16/211), creating an immediate hazard. The manufacturer failed to provide a timely remedy, initially misdirecting me to a dealer unable to service the model. Genesis and the local dealer now refuse to provide a courtesy tow to an authorized facility, despite the vehicle being disabled by their own safety defect. The vehicle has been stranded and unrepaired for over a month. This leaves my son at risk, as he must walk along dangerous highways during Extreme Heat Advisories while managing a spinal injury. The impact of being without a reliable, functioning vehicle at this address is not merely an inconvenience—it is a critical safety issue. We reside in a remote area where even emergency responders (EMS) have been unable to locate our entrance when responding to a recent medical emergency involving a hiatal hernia. Being without a vehicle that can reliably transport us or navigate to a main road is not a sustainable or safe position, and by refusing to remedy this recall defect, Genesis is directly contributing to this hazardous environment. I have explained this entire situation with Genesis Escalation without a resolution The safety hazard is compounded by the lack of local transportation. My son has been forced to walk along the shoulder of Highway 16 to get to work. He was recently stopped by a Texas Highway Patrol officer who checked his ID and expressed significant concern for his safety, warning him of the extreme danger of walking on that highway shoulder. While no citation was issued—as the officer recognized this is his only way to get to work—the incident confirms that the location is objectively unsafe for pedestrians.

Dealership refuses to make repair to fuel pump under recall and emailed me as follows: Cause of failure is the fuel pressure regulator in the high pressure fuel pump, the vehicle is setting DTC P0091, the vehicle does have an open campaign for inspection of DTC P0088 and if the vehicle does have P0088 it calls for replacement of the high pressure fuel pump. However since the vehicle is not setting DTC P0088 I cannot warranty under campaign 24-01-076G

FUEL/PROPULSION SYSTEM

5 times in the last 3 months the vehicle stalled while coming to a stop to put in park once, and 4 other times when the vehicle was off and parked, then started. The vehicle immediately began to stall out sounding as if it wasn't getting enough fuel. The last 2 times it stalled when being started, the vehicle remained on once I gave it a little gas by pressing the gas pedal when the stall started. The dealership is aware and performed a software update stating no components needed replaced and to keep an eye on it and a record of when it happens. Although it's believed to be an issue with the fuel pump, this specific one is not listed under the fuel pump recall.

FUEL/PROPULSION SYSTEM

When driving the vehicle it feels as though as it stalls due to choking all or some of the fuel getting to the engine. This is most prone when accelerating fast. It feels as though the fuel is shut off or severely diminished as the vehicle will accelerate, but at a fraction (crawl) of the normal output available and accomplished in the past.

FUEL/PROPULSION SYSTEM

Hi, I’m an Automotive technician writing on behalf of my Girlfriend. She drives a 2019 Genesis G70 2.0T. Her High pressure fuel pump failed Diagnosed by me. Throwing the Code P0088 which is a too high pressure in fuel rail system code. She was driving to work in the morning about last week and was on the highway when the car completely lost power and would not move at all on the Highway she takes to work. Fortunately she was able to get the car limped home safely and no one was hurt but after this I contacted Genesis about the open recall they have for the high pressure fuel pump and asked if they could help us out even though there was no remedy available yet according to them and we had no help. Case manager just told us basically we have to pay out of pocket and that Genesis will not reimburse us for this inconvenience. The bulletin they released regarding the Recall states if the car has a check engine light for the high pressure fuel pump that it would be replaced at no cost to the owner regardless of Warranty situations. But they refuse to help. That’s why I am writing this because my Girlfriend needs a working vehicle to get to work and safely. Genesis needs to own up because I should not have to pay over 1000$ out of pocket because of a manufacturer mistake.

NHTSA Recall Number 24V-107 I received notice of this recall in February. I was warned of a fire risk. I keep calling the dealer and reaching out to Genesis corporate and no remedy is available. It has been several months and this is unacceptable given the safety risk.

FUEL/PROPULSION SYSTEM

Since it was new, my 2019 Genesis G70 Twin Turbo with AWD has had occasional long hesitation (it happens every couple of days) when I step on the gas, lasting anywhere from 3 to 10 seconds. It happens from a stop, and also at times when the car is going 5-10 mph. The motor has been fully warmed up when this happens. When you step on the gas, the motor is still running but there is no response, no increase in engine rpm, then after a hesitation of up to 10 seconds, it kicks in with a sudden surge of speed. No warning lights come on. Needless to say, this is very dangerous when attempting to pull out into highway traffic, or simply maneuvering around in parking lots or normal traffic conditions. The danger is not just the failure to move, but also the sudden unpredictable lurch forward when it "catches". I brought it to the dealer several times, but it never hesitates when they have it, and they see nothing wrong. The car was scanned by an independent mechanic and he found no codes or any indication of a problem. I tried shutting off Electronic Stability Control but it didn't help. It happens in all modes, including sport mode. This is a continuous issue. The car currently has 12,505 miles on the odometer.
