2023 Genesis GV70

The contact owns a 2023 Genesis GV70. The contact stated that while driving approximately 80 MPH on a toll road, the vehicle suddenly stalled and stopped on the on-ramp. The contact pressed the accelerator pedal and the drove forward and operated as normal. The cause of the temperary failure was not yet determined. The manufacturer and local dealer were not yet contacted. The failure mileage was 13,000.

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.

I am reporting a recurring issue with my 2023 Genesis GV70 2.5 Prestige. The vehicle consistently shudders and shakes when driving between 40-45 mph under normal conditions—whether accelerating, cruising, or maintaining speed on various roads. This noticeable shuddering affects ride smoothness and is concerning. I brought this problem to the Genesis maintenance department at my local dealership. They inspected the vehicle but claimed no issue was detected. Despite their assurances, the shuddering persists every time I drive within that speed range. No repairs were attempted; I was told the vehicle was operating as expected. Researching online, I found numerous other owners experiencing the same issue. Forums, including Reddit discussions, are filled with accounts from frustrated owners. Many report that even after having their differentials repaired or replaced multiple times, the issue continues, suggesting a design or manufacturing flaw not being addressed. I am deeply concerned about the safety implications of this persistent shuddering. It affects vehicle handling and stability at common speeds, potentially leading to loss of control. The unpredictability leaves me anxious while driving, fearing a mechanical failure or accident. I do not want to be stranded due to this unresolved problem. This issue has significantly diminished my confidence in the vehicle and the brand. The stress and inconvenience are substantial, disrupting my routine and peace of mind. The inaction and lack of acknowledgment from Genesis add to my frustration. I am requesting a thorough investigation into this matter. The prevalence among other owners indicates a systemic problem needing prompt attention. I urge the National Highway Traffic Safety Administration to investigate these complaints to ensure Genesis resolves this defect and safeguards its customers. I hope that by reporting this problem, steps will be taken to prevent potential safety hazards for myself and other owners.

[XXX] At approximately [XXX] pm, while driving to Dallas, Texas, the car bucked numerous times while attempting to pass another car at approximately 65 mph. The GV70 then started to deaccelerate. The speed dropped to around 50 mph. I continued to press the accelerator, but the car would not accelerate but the engine was revving (RPM hit around 5000) and then dropped back down. I continued driving with the speed varying between 45 and 55 mph even with the accelerator floored. As I got closer to Dallas, I could get the speed up to 60 - 65 mph with the accelerator floored but then on any incline, the speed would drop back to 45 - 50 mph. I had to turn the hazards on several times as the speed was well below the other vehicles. There were no warning lights. I was able to get the GV70 into a dealer the next morning who kept the car for 2 days. They ran diagnostics and drove the GV70 but could not replicate the problem nor did the diagnostics sow anything. They thought that maybe the car reset when it was turned off. Issue has occurred multiple times since initial occurrence. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We were driving up a mountain pass in a great deal of stop and go traffic. The engine died and a check engine light came on. It was difficult to get the engine started, but it did start. We called the genesis service line and they said that it was a warning and ok to drive but to take it into be looked at. We proceeded up the mountain pass slowly, but when we were out of traffic and needed to give the engine gas to accelerate up the hills, the engine would not speed up. We were driving on interstates where we could only go 25 mph up the hill when others were speeding by us driving 60+ mph so we had to drive with our hazards in the right lane and hope not to get hit. When going down the hills, the engine would speed up, but any hills meant the speed would decrease even when you were engaging the gas. According the warnings we receive via Genesis in my app, the problem was Diagnostic code P0087F0 and said it was powertrain and the subsystem was EMS. We took the vehicle into the dealer and they were unable to recreate the problem. They reset the computer to the manufacturer reset. The vehicle is available for inspection upon request. This should not be happening on a 2023 car with 5000 miles on it.

Engine, transmission/propulsion and or fuel system is impacted. Vehicle loses power and pressing the throttle doesn’t increase the engine rpms and or vehicle speed. It happens randomly at both city and highway driving speeds. It’s almost like the gears aren’t shifting or the vehicle doesn’t increase the speed. Sometimes a it would work fine after a key cycle. I’ve had a few instances of it and there’s no check engine light. I took a video of it from last night when it happened. It’s a big safety risk trying to pass other cars. On the freeway when it happens the vehicle doesn’t cross 60mph hour. It’s very delayed, and then if I cycle the throttle or change gears or downshift manually it’s jump 2000-3000 rpms and would still struggle to get past 80mph. I bought my vehicle in MI, noticed these issues on my current trip to FL. I intend to have a MI dealer diagnose it. Seems difficult without a check engine light or DTC.

I purchased the vehicle on March 30, 2023, & my Check engine light has been on eleven times since June 2023. I was involved in a car accident on August 25, 2023, where the car appeared to have no gas. However, gas was in the vehicle, and the brakes were not operating correctly as I had to continue pumping the brakes to stop the vehicle. Furthermore, there is over $15k in damages and counting. I have been placed off work due to the injuries sustained in the vehicle accident due to the negligence of the manufacturer & dealer. I have left several messages for my Case Manager, [XXX] for several days, with unsuccessful attempts. [XXX] finally contacted me on 8/30/2023 @ 3:08 pm, apologizing for Genesis not living up to the “white glove” expectation advertised, and then she asked me what she could do for me. The call with [XXX] lasted 7-8 minutes. However, I constantly repeated myself, informing her of the information I stated in this email regarding my check engine light; my vehicle was serviced on Friday, June 30, 2023 (See Service History Below). Since then, the check engine light has illuminated nine other times with some of the same and or different codes. I had an appt to return my vehicle to the same dealership for the second time since June, as the dealership had the car for approximately eight/nine days. On August 12, 2023, I scheduled an appt. Per the system availability of August 25, 2023, @ 10 a.m. for Valet Pick-up. For confirmation of the scheduled appointment, I called GenesisCare on 8/23/2023, and the rep informed me that they did not have an appointment for me in the system. Furthermore, on several occasions, when I have attempted to make an appointment, the system does not recognize the appointment scheduled via the app or desktop. I was only informed about the technical issues with the software application via phone and desktop when I spoke with the service manager [XXX] ) Genesis of Atlanta. The accident occurred 8/25/2023.

No warning and no engine light when gas pedal is pressed down there is little to no acceleration. I was pulling out in the middle of traffic when this malfunction occurred. I could have been T-boned by oncoming vehicles and killed. It was not until I drove the vehicle a little longer that the engine light came on. The vehicles notification center showed a malfunction of the transmission. A diagnostic scan showed trouble codes P0763-Shift Solenoid C-Electrical and P0880-TCM Power Input Signal-Malfunction.
