2021 Genesis GV80 Engine Problems

On two separate occasions, my 2021 Genesis GV80 experienced a sudden loss of motive power while driving on Interstate 75 in Atlanta, Georgia, creating an extreme crash hazard. The first incident occurred on August 3, 2026. While traveling at highway speed in heavy traffic, I attempted to change lanes and pressed the accelerator. The vehicle did not respond — instead of accelerating, it crept along at low speed while surrounding traffic continued at approximately 80 mph. I was nearly struck by multiple vehicles and was only able to avoid a collision by steering back into my lane. The second incident occurred under the same circumstances on I-75 on but I don't recall the exact date. Again, when I attempted to change lanes and accelerate, the vehicle failed to respond and I was nearly hit by fast-moving traffic. Both of these occasions were terrifying. On August 11, 2026, I brought the vehicle to the dealership, where the entire transmission and heater box were replaced (vehicle in shop 29 days). Despite this major repair, the drivability problems continued — the engine RPMs race to 4 and 5 before the transmission shifts gears, and the vehicle drives roughly and feels unresponsive. The vehicle is currently at the dealership for replacement of the electric water pump. I am concerned this vehicle has an unresolved defect affecting acceleration and motive power that could cause a serious crash. The dealer's repairs have not corrected it.

Incident

Battery begins discharge without warning while driving the vehicle. System begins complete shutdown without warning. Experiencing clunking and or jerking while driving no matter if speed acceleration/deceleration. Infotainment system goes out of function without notice - radio, sound, navigation, and safety cameras included. I feel unsafe during driving this vehicle as it does not give any warning when these issues occur. Once in traffic I had to slam on breaks after the truck just shot off after lightly pressing the gas to move forward. Whenever the vehicle is taken in for inspection, no issues are found. I reported the clunking before, the dealer claimed it was a faulty fuel pump. This is a brand-new vehicle and none of these issues should be happening.

I bought my 2021 GV80 used with 15,500 miles. After driving not even 100 miles, we experienced the vehicle stalling and having no power. Giving it gas, the RPM's would not rise and the engine then shut off. The engine light briefly turned on but did not stay on. After the car shut down and turned back on, we kept driving. We took the vehicle immediately to the dealer where they proceeded to tell us there is nothing wrong because the diagnostics came back fine. But now this exact same thing has happened on 7 different occasions after driving a little over 1,000 miles. This has happened on the freeway, on busy intersections and feel unsafe to drive. On one occasion, we were almost hit from behind because we stalled making a left at a buy intersection. I took it back to a Genesis dealer and one week in their service, we were told they can't duplicate it and we should pick it up. Again, I do not feel safe driving this vehicle. There are no recalls but many complaints about this same problem and no recourse to fix this.
