2023 Genesis GV70: sudden loss of power

Filed Sep 26, 2026 · Engine, Fuel system · GA

The vehicle experienced difficulty starting, followed by the engine nearly stalling. Immediately afterward, diagnostic trouble code P0087F0 (Fuel Rail/System Pressure Too Low) was triggered and stored as an open code. This indicates the fuel rail/system pressure dropped below the level needed for normal engine operation, meaning the engine was not receiving adequate fuel. The failed component appears to be the fuel delivery/fuel pressure system (fuel pump or fuel rail). The vehicle is available for inspection upon request. My safety may be put at risk because the engine nearly stalled while driving, which could cause a sudden loss of power in traffic, while merging, or at highway speed. The problem has not yet been confirmed by a dealer; I have an appointment scheduled but the earliest availability was approximately one month out given the severity of the symptom. There were no prior warning lamps or messages before this incident. The trouble code and symptoms (hard starting, near-stall) appeared together for the first time on the date of this incident. I am also aware that other 2022-2023 Genesis GV70 owners have reported this identical P0087F0 code with matching symptoms in connection with known fuel pump/fuel line defects (the federal safety agency recalls 24V‑282 and a more recent 2026 fuel line recall). I checked the federal safety agency's VIN lookup tool and my vehicle does not currently show as included in either recall population, despite the matching symptoms.

My car exhibited a random loss of power which led to dangerous driving conditions. At times, when I wanted to accelerate to pass a vehicle on a two lane highway, I would enter the left lane to pass a vehicle and had zero acceleration which left me in a vulnerable position relative to oncoming traffic. Other times, the vehicle would not accelerate from a stop, rev to high RPMs and not shift out of 3rd gear without manual intervention. Another time, I was accelerating to make a lane change and the vehicle lagged, nearly causing a rear end collision by the vehicle behind me. There were no warning indications whatsoever on the dash, but I my OBD-II code reader indicated "P26CB00". When I researched this, I took my car into the dealer. The were able to replicate the problem and informed me that my vehicle had a punctured intercooler radiator which was caused by a road hazard and therefore would not be covered under warranty. After my inspection, I noticed a design flaw in the lower portion of the grill which allowed objects to impact the lower radiator without any protection whatsoever. Apparently, this leak caused my car's turbo system to not engage which is why there was a random loss of power. The repair of the radiator and water pump (which they said had failed because it ran dry) was over $2500. The dealer told me that they had had another Genesis GV70 with the same issue the prior week but that all cars have some unresolved problem or another. Based on my experience, this was a serious safety issue and so I also reached out to Genesis Corporate on 2/12/26 and they assigned it case #42240745. I have not heard back from them as of yet. Several people have posted about the issue on GV70 internet forums: [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Was driving on the highway at 70 mph. Oil light came on, noticed it without any loss of power. Within the next mile the cars rpms started to increase very quickly with little pressure being applied to accelerator and power loss started to begin. As I tried to get over and get to the next exit the car completely shut off in the middle of the road with little to no warning or time to react. Very dangerous. Thankfully was still able to steer and brake. I called help and had the state trooper blocking me on the road until the tow truck arrived. Massive puddle of oil & fluid on the ground under car.

While crossing through an intersection, the vehicle began to shutter and would not accelerate. I had just enough power to turn into a store parking lot where the vehicle lost all power, illuminated the battery warning light, and would not restart. After 30-45 minutes, the vehicle was able to start again using a jump box. I began a test drive around the parking lot and the vehicle shuttered again and lost all power while in the middle of the parking lot. At no point were we able to start the vehicle again however the battery continued to power the lights. Vehicle was towed to a nearby dealer. Prior to this there were a few instances where the vehicle either failed to start or failed to turn off after first pressing the Start/Stop button but I dismissed those as outliers since it would start up at the next activation. My vehicle lost power in the middle of a non-busy intersection and a quiet parking lot however this could've happened on a highway. Problem was confirmed by the nearby dealership Vehicle component has only been inspected by dealer No prior warning lights or messages other than what was mentioned.

On 5 separate incidents, on two separate days, when traveling at highway speeds, the car lost power and began to decelerate. After a moment the engine died. In each case I was able to coast onto the shoulder but this is a serious safety issue. On 6 further incidents, the car lost power and died in other circumstances, including in a driveway immediately after starting up. These cases were not as dangerous as the highway failures. Check engine light does not come on. No codes thrown. Dealer will not inspect for another month. Dealer has not yet inspected. Fuel, all fluids, all general maintenance is in good condition. Vehicle has less than 14k miles. Car is available for inspection upon request.

After my test, here's what I found: If the cruise control is Off and you press and hold the cruise control button for more than 2 seconds, the speed limit function activates as indicated by the "Limit" indicator on the multi-function display. In this mode, if the vehicle speed exceeds the limit speed and you press on the gas, the power is immediately cut off, and you can't accelerate. If the vehicle exceeds the limit speed, a warning bell will sound, and the speed will flash and power is cut when pressing on the gas. If the cruise control is ON, and you press and keep holding the cruise control button, sometimes the car will begin to slow below the set speed and continue to slow, even after releasing the cruise control button, and sometimes the cruise control will remain engaged after releasing the button. In this scenario, if you press on the gas to accelerate, the power is cut out and nothing happens even though you are below the limit speed. To restore power, you have to press and release the cruise control button to deactivate the cruise control. It's as though the cruise control gets into a mode where it won't hold speed, and pressing on the gas does nothing. This seems like a software bug. The above scenarios only happen when the cruise control is ON. Power is always available when the cruise control indicates that it is not activated or when in "Normal" (non-limit) mode when active. It seems counterintuitive that accelerating manually by pressing on the gas is overridden when in the "Limit" mode. I don't know if this is a design feature or a flaw. The vehicle lost power several times in traffic - and at that time do not believe the cruise control was being used The dealer says they cannot ascertain the problem and have referred it to an executive higher-level

Purchased the car 1/28/2023 and drove it off the lot with 20 miles on the odometer. Within the first 15 miles and merging onto a freeway, the motor cut out and we were almost rear ended. The sudden loss of power nearly caused a significant accident. We replicated the issue several times. We took the car to the dealership in our home state. We were told it was a fuel pump and water pump issue and they were seeing it in about 20% of the new cars. As of 2/17/23 we are still without our new car as it has been at the dealership since waiting for new parts. The dealership and the manufacturer knew of this issue and continued to sell and let people drive off their lots in potentially unsafe cars.
