Genesis GV70 transmission problems

POWER TRAIN

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.

I am writing to file a formal complaint regarding the service I received, and the dealership’s failure to address what I believe is a serious safety issue following recall repairs performed on my vehicle. On XXX, I brought my vehicle for a routine oil change and to complete three mandatory recall campaigns, including an ECM software update related to a misfire recall. Prior to this service, my vehicle had never exhibited any misfiring, transmission, or drivability issues. However, on Sunday, XXX, and again on Monday, XXX my vehicle began experiencing dangerous driving symptoms that started only after the recall work was completed. Specifically: The engine RPMs surge while accelerating, but the vehicle does not increase speed accordingly. The vehicle jerks when braking. The vehicle hesitates and feels unsafe while driving at highway speeds. These issues did not exist before Genesis performed the recall repairs. On XXX, I contacted my service advisor, to report these safety concerns. He assured me that a manager would contact me ASAP and determine the next steps. No one ever called me back. I called again that same day. During that conversation, Rick suggested that my worn brake pads and rotors were the reason my vehicle was “misfiring.” This explanation makes does not explain why my engine RPMs are flaring and the vehicle is failing to accelerate properly immediately after an ECM recall update. Once again, I was told someone would follow up, and again, no one did. On XXX, at approximately 9:00 AM, I called Genesis of Danvers again and spoke with Rick who told that if I dropped the vehicle off today, nothing could be done with it today, and that a manager would call me back. Got vehicle towed XXX. As of today XXX I still have no update on my vehicle. No phone card no email no loaner. I am becoming increasingly concerned by the lack of communication surrounding a vehicle that was towed because of a significant safety concern.

On XXX while driving at approximately 5mph in a parking lot my Genesis GV70 shifted from Drive to Park by itself causing the car and my wife and I to lurch forward and come to a stop! The car would not come out of Park and a warning came up after the fact saying to contact immediate service. My wife and I were in the car and there were no injuries. If this occurred at a higher rate of speed on a busy highway I cannot imagine what would have happened. I immediately called Genesis Road Assistance for a tow. The car was towed by flat bed to the dealer in [XXX], where I purchased the car, approximately 10 miles away where it sits today waiting for service. My wife and I are afraid to drive this car ever again as it is brand new with only 250 miles on the odometer. *No warnings of any kind prior to the incident.

My 2025 Genesis GV70 stopped accelerating properly. There is a lag when you push on the accelerator pedal and it must be pushed about 75% before it begins to accelerate. When it does accelerate it has much less power than normal. This fault occurs constantly. The car can't accelerate normally at any time now. This is definitely a very serious safety hazard. This behavior has been reproduced by Genesis service personnel. There are no warning lights associated with the problem and no diagnostic codes are signaled. After 24 days the Genesis service personnel have no idea what is wrong.

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.

I am writing to formally escalate a serious unresolved issue with my Genesis vehicle and the service experience I have received from Genesis of Huntington. My vehicle has experienced repeated and dangerous malfunctions despite multiple repair attempts. The most concerning issue is that the vehicle suddenly stops functioning properly while driving, accompanied by all dashboard warning lights flashing. In order to continue driving, I have had to turn the vehicle off and restart it. The vehicle has been brought back to the dealership multiple times for the same problem. Each time I was informed that the issue had been repaired and that parts had been replaced. However, the problem continues to occur even after these repairs. One of the most alarming incidents occurred while I was driving from Huntington back to Queens with my wife and newborn child in the car. The vehicle malfunctioned again, forcing me to stop and restart the car while on the road. This situation created a serious safety risk for my family. Additionally, the vehicle has been kept by the dealership for extended periods during repair attempts. As of my most recent interaction, the dealership had the vehicle for nearly two weeks during the third repair attempt for the same issue. Despite this significant amount of time, the problem remains unresolved. Compounding the issue is the lack of communication from the dealership. My attempts to contact the service department and management for updates have often gone unanswered, leaving me without information regarding the status of my vehicle. At this point, I have lost confidence in the reliability of the vehicle and the ability of the dealership to properly diagnose and repair the issue. I respectfully request immediate intervention from Genesis Motor America to review this matter. Given the repeated repair attempts for the same defect and the safety concerns involved, I ask that Genesis consider a permanent resolution.

The car has been shaking between 65-75mph and sometimes around 40-50mph since 9/7/2024. Car has been at the dealer service center 7 times, more then 30 days to attempt to resolve the issue, but nothing has worked. The last service visit they replaced the front axle. the car still shakes. I'm nervous something is going to fly off or a bolt is going to come loose from the shaking. I don't feel safe driving the car, but i don't have money to purchase another car. Genesis is aware of this safety issue and refuses to take action. I have a letter stating they were going to buy the car back by 12/15/2025, but they changed there mind. I guess they want people to drive unsafe cars. Don't buy a Genesis, Hyundai, or Kia. They don't stand by there word or seem to care if it affects there bank account.

I was entering a highway when my vehicle lost the ability to accelerate. Complete loss of acceleration, audible and visual notifications on my dashboard that were difficult to read as I was dealing with a dangerous situation. I was fortunate that there was a pull out immediately ahead and no traffic that allowed me to quickly get to safety. Had I been further up the highway or on a freeway, my life and that of drivers around me would have been in imminent danger as this was sudden and unexpected. After I pulled out, my vehicle dashboard contained a message that read: Stop vehicle and check power supply. My vehicle's app presents two "Attention Needed" notifications: 1) CHASSIS DTC C160C87 and 2) CHASSIS DTC P1A9096. My vehicle is only 2 years old and had all recommended recalls and maintenance checked prior to this event.

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)

I moved to Reno, NV where I need to merge onto route 80 everyday. During several attempts to merge onto 80, my Genesis GV70 stopped accelerating at 42 MPH, roughly 5000 RPMs and I was almost rear ended on two occasions because of the 'stalling' of the vehicle. An 18 wheel truck almost hit me because I couldn't accelerate past 42 MPH. Luckily, I was able to pull off the road. There was no warning light or check engine light on the dashboard. This was not a one time issue. Everytime I tried to merge at high speeds the car would not respond. I've attached a video that shows the issue. Genesis towed my car to a dealer in Mountain View CA. I did notice that I was leaking radiator fluid in the days prior to my incidents but when I checked the overflow tank, it was full. Again, there were no check engine lights on the dash. The Mountain View Genesis service manager replicated the issue and discovered that a small rock had come through the bottom grill and damaged the intercooler radiator. He unequivocally stated that "it's a design flaw in the lower grill. The grill has such a wide opening that foreign objects can enter through the lower grill." He went on to say that the intercooler radiator sits below the regular radiator and is made of a softer metal than the regular radiator which makes is more susceptible to damage. He also said that another Genesis GV70 came into his shop the same day with the exact same issue. The cost of the repair was $2,200 dollars to replace the intercooler radiator. (the intercooler was on backorder which may be demand) I opened a case with Genesis and they say that the repair is not covered under a warranty. The Genesis owners forum has numerous complaints of 'lack of acceleration' issues. Someone polled owners and 28 people responded that they experienced a similar lack of acceleration dangerous situation.

I moved my Genesis GV-70 to my home in Reno, NV. My complaint is in regard to my car becoming very dangerous! I'm giving you my move to Reno because its relevant to this complaint. I didn't need quick acceleration while I was living in Florida. In Reno, I have to merge onto Route 80 everywhere that I go. Acceleration during a merger is extremely important here in Reno. So what I've experienced in Reno is a VERY DANGEROUS situation with my Genesis. My GV-70 stops accelerating around 40MPH, or roughly 5,000 RPM. The transmission stalls out and the car revs at 5000 but does not respond. I've almost been rear ended by tractor trailers and other vehicles because of this dangerous situation. I have since found out that my recall for a ECM Software Update-P030X Misfire problem is the acceleration issue that I've described. Here is my complaint: My car should not be allowed to be driven in this current condition. Genesis has understated the severity of this issue dramatically and certainly the language in their recall letter didn't reference not being able to accelerate past 40 MPH/5,000 RPM. I didn't experience this issue while driving mostly local roads in Fort Myers Florida, but here in Reno, this car and it's condition is DANGEROUS! It has caused near misses with very catastrophic consequences. I am driving my car to Rocklin California (2 hours away) next week for service which includes the Misfire problem as well as other service issues. The Misfire recall should taken my car off the road, Genesis did not address the severity and dangerous possibilities of this issue.

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.

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.

Started car. Would not accelerate past 30-40 miles an hour even when I pressed the Gas Pedal to the floor. I pulled over and turned the car off. On restart it seems to be fine. The Genesis GV 70 forum is replete with owners having the same issue. This is a 2022 with less than 25,000 miles on the Odometer. There are not many of these cars on the road and probably many owners are unaware that this seems to be a recurring issue on many of these models. I implore the NHTSA to look into this matter quickly before fatal accidents , if they haven’t occurred already, happen.

GENESIS DEALER ISSUES OF TAKING ON SERVICE FROM CLOSED GENESIS DEALERS, NO APPOINTMENTS FOR MONTHS, NO LOANERS & UNABLE TO REPAIR AND/OR MULTIPLE REPAIRS FOR THE SAME ISSUE ARE REAL AND AFFECT A SIGNIFICANT NUMBER OF GV OWNERS. These issues are now insurmountable for the near term and, at 72 years old, the "near term" is very important to me. GENESIS AND NHTSA ARE NOW WELL AWARE OF THESE DIFFERENTIAL ISSUES WHICH CAN RENDER THE VEHICLE INOPERABLE WHILE DRIVING OR PARKED. A NATIONAL RECALL IS REQUIRED AS WELL AS A "PERMANENT" FIX. CURRENT DEALERSHIPS ARE HEAVILY IMPACTED WITH PICKING UP MANY ADDITIONAL SERVICE CALLS FROM CLOSED GENESIS DEALERS. THEY DO NOT HAVE THE CAPACITY OR THE ABILITY TO PERMANENTLY REPAIR THESE ISSUES IN A TIMELY MANNER.

[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)
