2023 Genesis GV70 engine problems

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.

I had noticed my GV70 had not been functioning correctly for about 3 weeks prior to scheduled maintenance due. The vehicle has become slow and sluggish accelerating. Was concerning as I had pulled out in traffic not expecting limited acceleration. NO check engine or warning signs displayed. I traveled from Midland, TX to Genesis of Grapevine for scheduled maintenance to be performed. Later that day was informed that my radiator had been crack. Due to road debris and my extended warranty would not cover it most likely. Of course road damage would have had caused this as my expensive vehicle has never been off road. After researching Genesis Forum I have learned that this is a structural defect that has been corrected on later models. So Genesis has obviously taken corrective measures to prevent this from happening on newer year models. This is something that should have been corrected with a recall. Now it is being deemed as road damage. Please look into this.

CORRECTION TO the federal safety agency COMPLAINT 11754243 (8/2/2026). That complaint was submitted late at night with assistance; several fields were entered wrong and the electrical failure history was omitted. Apologies for the error. Please associate this with XXX. CORRECTIONS: Vehicles towed - YES, TWO, not "No"; my Genesis is still at the dealer it was towed to in [XXX]. Injured - THREE, not 1. Police report - YES, not "No". Mileage about 23,500. Speed at T0 per the EDR - 23 km/h, about 14 mph. OMITTED AND MATERIAL: Before this crash the vehicle STARTED ITSELF TWICE WITH NO HUMAN COMMAND - no key press, no remote start, nobody in it. Separately the entire system went completely black, causing TOTAL ECU AND ECM FAILURE. The vehicle lost electrical integrity. WHY THAT MATTERS: Genesis Service Campaign 914G is "ECM Update - P030X Misfire"; its remedy is "Update the ECM (Engine Control Module) software." It covers 2022-2023MY GV70 (JK1) built 3/29/2021-3/4/2025, VIN starting KMU. My VIN is [XXX], a 2023 GV70. Owner notice was due September 2025. The campaign was still open and unremedied when the car crashed 12/3/2025. THE EVENT: Exiting a highway at low speed with no impact, collision or obstacle of any kind, the airbags deployed spontaneously. The deployment caused loss of control and a three-vehicle collision. The deployment caused the crash. No warning lamp or symptom preceded it. FAULT HISTORY: B139500 cross coupling (SRS firing-loop interconnection fault), B1650 (airbag control unit fault history), and multiple LOW VOLTAGE codes. An electrical system that starts an engine uncommanded and blacks out an ECU can fire a restraint with no crash. EDR: The report states the EDR is part of the Air Bag Control Unit and that if ACU power is lost during an event, all or part of the data may not be recorded. Manufacturer closed its claim with no repair or explanation. Vehicle and ACU remain available; no dealer diagnostic was done on the ACU.

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)

Genesis uses soy-based wiring in the engine without any rodent protection. We had rats chewing the wires in the engine last year in April, for $6.9k repair cost and again this year in February for $7.4k in repair cost. This car cost way too much to own, the repairs take about 5 to 6 weeks to complete, and most importantly this cat is a major safety concern to me and my family.

Several times now, my Genesis GV70 will make a strange sound on startup. The auto stop light will illuminate and I can't turn it off. The car will have no power to accelerate. I have to turn the car off and back on again for the problem to resolve.

I purchased this vehicle brand new in July 2023. By Jan 2024, it was already having major issues. The 2 major issues with this vehicle are 1) it had an engine misfire ( thus engine and fuel system issues) that cut the power to the vehicle and made it dangerous to drive and thus had to be in at the Genesis dealer service center 3 times (Jan, April and May 2024). The 2nd problem is electrical. On Oct 1st, 2024 the brake lights wouldn't turn off at all despite several troubleshooting attempts. That electrical problem drained the battery and after the car was jump started, after I started to drive, then the car cold died in the middle of the road. I had my 10 day old newborn in the car and I had to get out and stop cars that were driving towards me. Attached is the repair invoice for the engine misfire earlier this year and the car is currently at the repair facility for the electrical problem so no invoice has been generated yet.

I had just started the car and driven less than half a mile in a 35 MPH zone when the acceleration gave out. Vehicle would not go over 20 MPH, engine did not rev up when gas pedal depressed. I came to red light and stopped, turned off the car and turned it back on and issue seemed to clear. I google and have learned this model and year are being recalled for this issue and fuel pumps replaced, but my VIN does not show up as under the recall. I'm now afraid to drive my car.

I was sitting at a stop light waiting to make a right turn. When I pressed down on the accelerator the car just inched forward. I let off the gas and pushed the accelerator again and again before the car would accelerate. This has happened several times, once almost causing me to wreck. This has happened since the first month I purchased the vehicle. I have had it for a year
