The Engine Control Module (ECM) malfunctioned. The dealer replaced it with a new one. When it malfunctioned, the car would not accelerate to a speed greater than 20mph. This was dangerous because I was driving on a state highway where the speed limit is 55mph, and I could have been rear-ended. Since having the ECM replaced, the car's performance has been fine. The Check Engine light did activate more than one day before the incident, which also sent a message to the Genesis app on my phone.

What owners say
4/2/26, very hard to start the engine and engine warning light was blinking. noticed significant amount of fuel leaking on driver side of engine.

While driving through a parking lot on [XXX], leaves blew in front of car and it automatically came to an abrupt stop. While driving on [XXX] on [XXX] at approximately 70 MPH, without any encroaching vehicles and with no road obstructions, the automatic emergency braking temporarily engaged on 2 occasions, indicator on dash indicated that it occurred, and I felt the wheels lock up for a short time. Fortunately, there was nobody very close behind me and I was able to maintain control of the car. In neither of these instances, did I physically apply the brake. I continued to drive the vehicle home at a decreased speed and have parked it in my garage. The vehicle mileage is 27043 and has no damage. An apparent dangerous malfunction with the vehicle's ADAS system (possible computer, camera or sensor.) I have spoken with the dealer and they are arranging to pick the vehicle up from my house. Unrelated, I had the vehicle oil changed at this same dealer (Genesis of Cherry Hill) at 6,000 miles and had to have it towed back to them the next day because they overfilled the oil, the CEL illuminated and it developed a misfire. Likely caused internal engine damage and flooded the VVT solenoids and likely aerated the oil, reducing its lubricating capability.

The contact owns a 2022 Genesis GV80. The contact stated that in November of 2023 while driving at 80 MPH with cruise control engaged and approaching another vehicle, the contact changed lanes and the vehicle automatically slowed down. The contact stated that while returning to the set speed, the warning lights except for the check engine warning light illuminated on the instrument panel. The vehicle was taken to the dealer where the vehicle was diagnosed, and it was determined that the battery was not maintaining enough voltage for the ECU and that the battery needed to be replaced. The battery was not replaced because the dealer did not have the battery in stock. The contact was informed that he could go to any Genesis dealer, and the battery would be replaced if it was in stock. The contact drove the vehicle to Houston, TX in December of 2023 and the failure reoccurred with the check engine warning light and other unknown warning lights illuminated. The dealer, Genesis of Spring (20440 Interstate 45 N, Spring, TX 77373) informed the contact that the battery did not need to be replaced but the ECU needed to be replaced. The contact stated that the ECU was replaced. The contact stated that on [XXX], while his wife was driving and had stopped the vehicle in the driveway, without warning all the side air bags and seat air bags deployed. The seat air bags located in the front driver side and passenger seats as well as the seat air bags in the rear driver seat and passenger seat. The frontal driver’s side and passenger’s side air bags had not deploy. The contact stated that the air bags warning light was not illuminated before or after the failure. The Insurance provider was contacted and had the vehicle towed to a USAA repair facility. The vehicle was inspected by a Genesis engineer at the repair facility. The manufacturer sent an email stating that no assistance would be offered as the air bags had not deployed due to a manufacturing defect. A case was opened with the manufacturer. The vehicle was not repaired. T

The contact stated that the vehicle was taken to the dealer on two occasions, where the ignition coils and unknown parts were replaced however, the failure recurred. The vehicle was taken back to the dealer, where the contact was informed that the VIN was included in the federal safety agency Campaign Number: 24V282000 (Fuel System, Gasoline). The dealer determined that cylinders #1 and #3 were misfiring. The dealer replaced the #2 fuel injector. The contact stated that upon picking up the vehicle from the dealer, the check engine warning light was no longer illuminated; however, there was a strong gasoline odor inside the vehicle, and the odor persisted while driving. The vehicle was taken back to the dealer, where it was test-driven, and the contact was informed that the odor was no longer present.

On two occasions in the last month the car has suffered a loss of power with the accelerator unresponsive to input. After 5-10 seconds of this still actively occurring the car began to shake violently while I was trying to find a safe place to stop the car out of the traffic lanes. Within a minute or so things would go back to normal. The first time I was in a 35mph zone so the car was relatively controllable but unable to keep at speed. The second time was on the interstate at 70mph in heavy traffic. The car reacted much more dangerously at this speed. The loss of power was more severe and the violent bucking and shaking of the car was very severe. I thought parts would start falling off the car at any moment, it was that violent. With my emergency flashers on I was able to exit the interstate without accident or injury but there was a bit of luck involved. It could have just as easily gone very badly in the heavy traffic. There is an open recall on the Genesis GV80 for the fuel pump needing replaced for this exact type of occurrence. [XXX] ). While my VIN is not part of the formal recall I feel 100% certain that this is the same exact issue. Numerous others with GV80's have had and are still having the exact issue. The car was dropped at the dealer (Genesis Bedford OH) last week. They kept the car for a week but were unable to duplicate due to the randomness of the issue. They returned the car without fixing the issue. They never mentioned anything about the GV80 fuel pump issue. I have an open case ([XXX]) with Genesis but they are refusing to replace the fuel pump or rectify the issue in any way. As is noted in the recall of the fuel pump this issue does not cause any check engine lights to activate nor is Genesis storing any type of code from the issue. The recall clearly states that a car with this fuel pump issue should not be driven. Genesis is currently refusing to assist me in getting the car fixed.

When I was driving my 2023 GV 80, I was applying pressure onto the gas pedal and the car suddenly started jerking. The car was not accelerating then the check engine sign came on and then the car completely turned off. Then I restarted the car and it was moving really slow. Similar incident happened few other times and luckily I was able to pull over to the parking lot after turning on the hazard light. I drove my car over to the dealership and dropped it off. I am afraid that someone is going to get killed in an accident while they're driving on the highway or crossing the streets
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.
I have been driving my car and it will automatically flip to neutral and start blinking all sorts of engine lights. I can sometimes stop the car and restart it, and it will be okay, but it typically takes a few tries. It has happened after I start my car and am in the driveway, when I'm going ~40MPH and when I'm on the interstate going >70MPH. I have an infant and have been in the car with him when this has happened. This is obviously anxiety inducing anytime I get in the car, but even more so when I need to transport him. I have requested a loaner car from multiple Genesis dealerships until they can diagnose and fix it, but most do not have appointments until September and expect me to drive my car until then.
1) This vehicle was taken in for the seatbelt pretensioner issue and was turned away due to 'no replacement parts on hand'. To be clear an appointment was made indicating this is the service needed and the dealer could not complete the work. 2) Additionally this vehicle suffers from a sudden loss of power on the highway. If vehicles are following too closely there could be a serious accident. The failure mode of this condition is triggered by high temperatures 105 to 107 F there is a persistent DTC code P0087000 which indicates inadequate fuel pressure and maybe caused by fuel pump, pressure regulator, or sensor. At least once, when the car cools off the main computer (referred to 'the head unit' by Genesis customer care) can be 'reset', and all DTCs are cleared and Check Engine Light is cleared. Several owners of G70, GV70, and GV80 owners are reporting similar "sudden loss of engine power" on the owners forum.
