2025 Genesis GV70 Transmission and drivetrain Problems

“I believe my transmission is slipping. I had four events within the last 3-4 weeks. 1) after my car was running for 30 minutes, I started to slowing go up a hill from a stopped position. The car accelerated on its own and I had to slam on the breaks. I was very scarred. I did not see a warning light in dash. 2) I was pulling away from a stopped position after my car was running for 15 minutes. The car would not move and the RPMs went up to four. After five seconds, the car finally moved. 3) the car would barely accelerate after first starting 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. …”

“Vehicle has physically and forcibly moved both forward and backward, on its own, after being placed in Park and the engine turned off — including after occupants have exited the vehicle. This movement has struck the driver and two minor children on multiple separate occasions, as well as nearby curbs and objects, without physical injury. No warning lamps or dashboard messages appeared before or during these incidents. Because the movement occurs after occupants have exited the vehicle, it is unknown how many additional times this may have occurred unobserved. …”

“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.”
