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. …
While driving on the highway, the car shut down with no warning messages and gas fumes filled the interior of the car. I was not able to move over to a completely safe spot on the road because the car shut down so quickly. I was not able to put the windows down as there was no power to the car and unable to exit the car because I was not in a safe spot on the highway. I had to remain in the closed car inhaling the gas fumes. I called 911 and they had me sit in the sheriffs car until a tow truck came to keep me out of the fumes. The car was towed to the dealership, it had 53 miles on it. This event was extremely dangerous. It is currently at the service department of the dealership for repairs.
The contact owns a 2025 Genesis GV70. The contact stated that while on the highway driving at 55 MPH, the vehicle suddenly stopped. There were no warning lights illuminated. The vehicle was restarted. The vehicle was towed to the local dealer, but they were unable to determine the failure. The vehicle was not diagnosed or repaired. The contact was provided a loaner vehicle. The manufacturer was contacted, and a case was opened, but no additional assistance was provided. The approximate failure mileage was 13,500.
The vehicle has 1500 miles on it. I was driving around 40mph when the engine suddenly lost power and the immobilization light appeared. I was no longer able to accelerate. I coasted to a side street where the vehicle placed itself in Park. I restarted the vehicle and it worked. The next morning, the vehicle would not start and the immobilization light was present again. After checking the key fobs and battery, roadside assistance and I could not find the issue. Remote start from the app also did not work. It was towed to the dealer for assessment which is where it currently sits. If this happened on my regular highway route, I would possibly be stranded in the middle of the highway endangering me and others.
I am filing this formal complaint against Genesis Motor America (a division of Hyundai Motor America) for the repeated failure to repair my defective 2024 Genesis GV70. The vehicle has been a nightmare of safety hazards, financial ruin, and life degradation, with over 240 days out of service in 8 months. This saga began as a dream purchase, but quickly turned into a relentless horror story of mechanical and ADAS failures, dealer incompetence, and manufacturer indifference. The vehicle has been in the shop on six separate occasions under three (3) different dealers, with collective downtime exceeding 240 days, far surpassing Florida's Lemon Law thresholds (3+ repair attempts for the same defect or 15+ days out of service).
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. …
