Genesis GV70 Problems — All Years, Common Issues & Reliability

The driver‑side display on my 2026 Genesis GV70 randomly goes black or becomes distorted. This defect is included in Recall No. 26V019. Despite this, Genesis Consumer Affairs and the dealership (Homestead Hyundai/Genesis) refuse to perform the required software update that corrects the issue, claiming the vehicle is “already updated” — a statement that directly contradicts the official Genesis documentation, which I personally obtained. Instead of applying the required software upgrade, the dealership replaced the monitor. The replacement failed in the exact same way, proving the issue is not hardware‑related. When the driver‑side display goes black, I lose critical driving information, creating a clear safety concern. They refuse to update software.

I leased a 2026 Electric GV70 from Genesis in June 2025. In January of 2026, when driving the car I got a warning sign to stop the vehicle and check the battery supply. At that point, the car went into sever power reduction and would only go 20 MPH or so. After 20-30 minutes, the car completely shut down and became inoperable. Luckily, I was near home and was able to get my car home. I had to have the vehicle towed on wheels as it was completely frozen to the dealership. They diagnosed it as a failure of the Integrated Charging Control Unit (ICCU). They replaced the ICCU but identified other issues that to this day are unresolved and my car is still in the shop. These cars were subject to a recall for ICCU failure but only to model year 2025. These ICCUs are continuing to fail on the 2026 models, and at an alarming rate. The head of service at the dealership told me they were dealing with "hundreds" of ICCU failures on Hyundai/Genesis vehicles. If I had been on a highway traveling at higher speeds and the car suddenly lost almost all power and would only drive for another few miles before completely shutting down, it would have created a dangerous situation. These cars need to be recalled - again. Hyundai/Genesis clearly dont know how to make electric cars/battery packs that work and should be held accountable. I believe they are downplaying this situation due to the prior recalls/class action lawsuits and dont want to experience further reputational damage.

This happened in an Enterprise rental car. Now I will be fighting against loss of rental and rental damages to car my insurance company provided because of a claim on my personal vehicle. I was driving northbound 270 merging onto westbound 64 in St. Louis, Mo, when the back windshield spontaneously exploded. I thought it was a gunshot, checked my body for damage; none found. Looked in my rear view mirror and saw the entire back windshield was completely cracked.

When stopped at a stoplight with my foot on the brake and the transmission in drive (D), after 15-30 seconds, the transmission shifts into park and the engine starts. (the autostart was in the default position). This has occurred repeatedly. The the autostart button is pressed and the light is on, the transmission reacts normally. I have a video but it is larger than 10MB

1. What component or system failed or malfunctioned, and is it available for inspection upon request? Driver assist systems, including lane keeping assist, forward collision avoidance/braking system, and related exterior sensor systems, are malfunctioning. The lane assist system has taken unintended control of steering, and the braking system has activated without cause. Yes, the vehicle is available for inspection upon request. 2. How was your safety or the safety of others put at risk? The vehicle has exhibited unintended braking and steering intervention during normal driving conditions. Most recently, the lane assist system abruptly jerked the steering wheel while passing a side road opening, forcing the vehicle into a curb and causing damage. These unpredictable actions create a high risk of collision, loss of vehicle control, or being struck by other vehicles, especially in active traffic conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The vehicle was brought to the dealership for inspection; however, the issues were not reproduced during testing. Testing occurred under dry weather conditions, while the malfunctions primarily occur in wet, cold, snowy, or icy conditions. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by an authorized Genesis dealership service department. Genesis Consumer Affairs has been notified and is aware of the reported issues. No other third-party inspections have been performed at this time. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There have been intermittent warning messages & dashboard indicator lights related to driver assist and system functionality. These warnings have appeared inconsistently and not always at the time of the malfunction. The problems began after 30K mi and returning to NY.

Hyundai/Genesis 2026 GV70 2.5T Advanced. Drivers side instrument cluster goes blank/black, dangerous. Contacted Genesis Customer Care, doesn't know how to fix my model/trim. Representative, hung up on me. Dealer: Homestead Hyundai/Genesis doesn't have tools to fix the problem..

Without any warning, on March 15, 2026, I turned out of a parking lot onto a major road and I noticed it wouldn't accelerate above 20 mph, so I pulled off the road. I tried again and my vehicle still failed to accelerate. And on my third attempt, my vehicle decelerated and was about to completely stall. I managed to turn into a parking lot and avoid getting rear ended. However, this could have been a fatal event. While I was trying to accelerate, the vehicle was quiet as if the car wasn't even running. After shutting the engine off for awhile, I was able to drive the vehicle with caution. I reached out to two Genesis service departments regarding my vehicle failing to accelerate while driving and neither had heard any previous complaints, and the earliest appointment would be mid April. There was no sense of urgency, as I'm left to hesitantly drive my vehicle at the risk of it happening again and getting rear ended. And when my vehicle does go in for service, I'm weary whether the problem will be resolved properly since the service department is unaware of the issue. In addition, I have had this vehicle for only 4 months and 1 month into it, I already took it to service because of fuel odor that had not gone away since the day 1. But the service department didn't find anything wrong with the vehicle, so nothing was done to it. I also swung by another Genesis service department, in case they happened to be familiar with the cause of the odor. My vehicle still has the fuel odor and now I'm wondering if that is related to my vehicle not accelerating. I am seeking your assistance to ensure that the problems with my vehicle are confidently resolved. And I wouldn't want this to happen to anyone else. I am thankful, I was driving and not my teen.

This is my second GV70 I had a 2024 and now a 2025. They had to buy back my first car due to the exact same issue. I was assured that the new model which I bought a different Hyundai in between the two GV70’s. I have owed over 100 cars and I truly love the Genesis but the SUV is Totally Unsafe to drive with the cruise control. The cruise control will slam on or firmly apply the breaks for zero reason. You will be driving no one around at all and the breaks come on. I have been almost rear ended several times. This happened the very first day I drove the car on I75. It happens daily that I am on I75 so I now only use the cruise control when there is no traffic. On my way to Lexington it happened 5 times. But now it’s getting worse. This will eventually kill somebody. I have been very nice but once I got tired of waiting for the dealership to do something about it I went to Genesis directly and now the dealership refuses to let me come back due to my complaint. The dealership Genesis of West Knoxville refuses to fix the problem and Genesis told me to go to the BBB. . Well the BBB is not the answer if someone dies due to this very serious situation. PLEASE help before someone dies. I have had two different dealerships service department people tell me they seen this before and even my first Genesis rep said this is an issue now they all say they never said it. And Genesis even took my advocate away and gave me a new one that I had for months and months and within a few days the new one said Genesis sees no reason to go any further. Thanks in advance for your help. Ron Garrett 931-303-4882

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.

Got a "power limited, check electrical system" warning when starting the car. Towed it to the dealership and they told me the ICCU failed and it needs to be replaced. It has been over 5 weeks and still waiting for the part to be back in stock.

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.
