I am reporting a potentially serious transmission safety issue involving my 2022 Genesis GV70 2.5T AWD. While traveling on [XXX] through [XXX]’s Grapevine, my vehicle unexpectedly jerked and appeared to slip out of gear. Engine RPMs increased to approximately 3,500–4,000 without corresponding acceleration and remained unusually high, including while driving on level ground. No warning lights or error messages appeared. The symptoms recurred after restarting the vehicle. The vehicle subsequently experienced complete loss of propulsion and would no longer move in Drive or Reverse, despite the engine revving. Genesis Santa Monica confirmed the no-movement condition. According to repair order #XXX, technicians found transmission fluid approximately one quart low, dark brown, and burnt-smelling. They added fluid, reset adaptive values, and performed a transmission control module relearn. No diagnostic trouble codes were found, and the vehicle remained inoperable. The dealership recommended transmission replacement at an estimated cost of approximately $15,000. I am concerned that an unexpected loss of power while traveling at freeway speeds could create a serious collision risk, particularly when no warning indicators appear. I request that the federal safety agency review this incident for a possible transmission-related safety defect and determine whether similar failures are occurring in other Genesis GV70 vehicles.

What owners say
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.
The vehicle has experienced a pattern of recurring electrical failures beginning shortly after purchase, involving driver door controls (window, lock, mirror, and interior lighting functions), which have required four separate repair attempts over approximately three years, including replacement of a door module, a wiring harness, and a door switch assembly. Despite these repairs, the same driver door electrical failure has recurred multiple times. The vehicle has also experienced a seat memory module failure (module was replaced), and a persistent rear hatch malfunction that has never been resolved. The most serious concern is that the vehicle has, on multiple occasions, unexpectedly shut down while being driven, including instrument cluster and infotainment screens going dark, occurring when the automatic engine stop/start feature engages at intersections. The vehicle has restarted on its own after acceleration in some instances. Power steering assist has also been affected during at least one of these events. Most recently, the vehicle failed to start at all on one occasion, requiring roadside assistance to jump the battery; the dealer diagnosed unstable battery voltage but did not identify a root cause connecting this event to the prior shutdown incidents. This creates a significant safety risk due to potential loss of vehicle control or loss of power while operating in traffic. The problem has been reproduced and confirmed by the dealer on multiple occasions (door module and wiring harness failures were diagnosed and repaired), though the shutdown-while-driving events specifically have not been duplicated by the dealer despite multi-day testing. The vehicle has been inspected exclusively by the authorized dealer; it has not been inspected by police or independent parties. Warning symptoms (flickering door lights, dead door controls) preceded the shutdown/stall issue by roughly a year before the stalling symptom began.
My vehicle is at the Genesis dealership with what they even consider a common problem. Road debris putting a hole in the unprotected Turbo Intercooler Radiator. This is a safety issue because the loss of power in the vehicle once you lose your turbo. The radiator is very unprotected down at the bottom of the front of the vehicle and Genesis needs to do something about this. This is going to cost me $1500 to fix there not covered by Genesis even though it's a serious design flaw. I know I'm not the first person to report this, as I've seen forum posts about it and the issue is quite common. If it's so common, and it's so vulnerable, there most definitely is a design flaw in the vehicle.
I do not know exactly what component failed. All I know is that the vehicle lost power while my wife was driving our children to school at around 8:15 A.M. on February 24, 2026. The vehicle slowed down on its own and could not accelerate when my wife pushed on the gas pedal. There were no warning or check engine lights on the dashboard. Luckily, this happened in a residential neighborhood where traffic is low. This could have caused an accident and/or fatalities if she was driving on busy street or a highway at the time. I contacted Genesis Customer Care. They scheduled me for a service appointment to get the vehicle checked. The vehicle was checked for codes, but nothing came up. They checked the vehicle log but did not find any clues. They told me that everything was normal and they assumed that it was most likely due to an over-the-air update that caused a system reboot. I believe the problem still exists and that it is a matter of time before it happens again.
While driving an audible pop from the rear of the vehicle was heard. Upon hearing the pop the vehicle warning lights came on and a sudden loss of power reducing my maximum speed to 20 mile per hour. The electrical system failure warning came up on the screen and the car would not accelerate to over 20 miles per hour. The dealer stated it was a failed ICCU and fuse. This has been at the dealer for over 10 days without a return window provided. The car has 15,802 miles on it.
Loss of power, warning to check EV system.
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)
My vehicle failed while in motion. I lost power to the vehicle and power steering. Just before the car failed, I heard a pop and a warning light came on that said "Check Electric Vehicle System". The car's ICCU failed and caused failures of the battery and 12v battery. My safety and everyone on the road around me's safety was put at risk when I lost the ability to accelerate or use power steering. The car was towed to a dealer and the dealer confirmed the issue. The ICCU failure and failure of the vehicle while in motion is directly related to a previous safety recall (025G) for which repair work was done on my vehicle. The recall repair was ineffective as the very issue it was intended to resolve still happened to me in a 1 year old car with only 8,000 miles.
The coolant system on my 2022 Genesis GV70 has repeatedly failed despite multiple repairs. On April 2, Greenway Genesis diagnosed a coolant leak and replaced several components. The problem returned, and I brought the vehicle back on April 29 because the coolant appeared low again and the engine sounded louder than before. On October 25, Holler Hyundai confirmed another coolant leak, this time involving the integrated thermal management system. The recurring coolant loss places my safety at risk because it can lead to engine overheating, sudden power loss, or engine failure while driving. The issue has been reproduced and confirmed by two separate Genesis/Hyundai service centers. However, the root cause has not been identified or corrected, and the manufacturer has not provided a permanent solution. The vehicle has been inspected multiple times by authorized dealerships, and repair invoices are available for review. Despite these failures, no coolant warning light or dashboard message ever appeared, which raises concern that a sensor or monitoring component may not be functioning correctly. There were no warnings or messages at any point before or during the coolant loss. The vehicle is currently at Greenway Genesis and is available for inspection. Based on multiple repeated failures and the absence of any warning indicators, there appears to be an unresolved defect that could create a safety hazard while the vehicle is in operation.
