2023 GENESIS GV70 Power Train Problems

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.

Transmission failure at 1558 miles. Replacement of transmission assembly is required. Dealership (Manly Genesis of Santa Rosa, CA) has the vehicle. No confirmation date of when parts and work will be completed.

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.

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.

Rear Diff replaced three times. Multiple reports of people having the same problem.

-rear differential -risque of failure of delivering power to the wheels and stopping in the middle of traffic -yes -the component inspected by the dealer and been replaced -the only warning is a loud noise when you drive above 50 mph and it appeared in the early miles of the first 5400k

All wheel drive(AWD) warning light illuminates. 9482 miles have been driven on the vehicle. This has happened 5 times in the last week, April 25th- May 1st 2023. The vehicle was taken to the Genesis dealer on the 1st of May 2023. I was informed by the service department that several components related to the differential system and parts were ordered. Relief valve, actuator assembly, pressure sensor. I was informed that this may or may not fix the issue. Additional parts will have to be replaced. If that doesn't fix the issue the entire unit will have to be replaced. I asked if this was a safety problem and is it safe to continue driving my vehicle. The answer I received was they didn't know. There were no other signs or symptoms prior to this. As far I can tell the vehicle runs ok. I also don't know if the traction control system will malfunction while I am driving. I picked it up and drove it home and I haven't driven since. I called the Genesis hot line on May 1st 2023 and asked was if it is safe to drive the vehicle. As of May 2nd I haven't heard back from them.

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
