2022 GENESIS GV80 Fuel/propulsion System Problems

Since the coasting feature on the Genesis GV80 and similar models is inoperative, it could mean that Genesis misrepresented the vehicle’s fuel efficiency and emissions performance. The coasting function is designed to disengage the engine from the drivetrain to improve fuel economy, and because it doesn’t work as advertised, real-world MPG may be lower than stated. This could mislead consumers who purchased the vehicle expecting better efficiency. Additionally, coasting reduces engine load and fuel consumption, meaning that with it disabled, carbon emissions could be higher than what was tested or certified. Since official EPA fuel economy ratings were calculated with the assumption that coasting is active, but in practice, the feature never engages, this could be considered a form of emissions cheating or consumer fraud. Such discrepancies raise regulatory concerns and provide grounds for legal action, including a class-action lawsuit, if buyers were misled into purchasing a vehicle under false claims.

Subject: Complaint Regarding Genesis GV80 Coasting Feature Malfunction in Eco Mode To Whom It May Concern, This complaint is regarding a defect in the Genesis GV80’s Eco Mode, specifically the failure of the vehicle to coast as advertised. Genesis promotes the coasting feature as a key function of Eco Mode to improve fuel efficiency, yet this feature does not engage at all during real-world driving. Multiple owners have reported this issue to Genesis dealerships during service visits, yet no fix has been provided. Despite being aware of the problem, Genesis has not issued any software updates, recalls, or technical service bulletins to address the malfunction. This misleading advertising impacts vehicle performance and fuel economy, creating frustration among customers who purchased the vehicle based on these claims. The National Highway Traffic Safety Administration (NHTSA) is urged to investigate this matter and hold Genesis accountable for failing to deliver on its advertised vehicle functionality. A resolution

My Genesis is going to get me killed! The dealership has informed me that since it doesn't give them a code, they can't fix the issue. Here is a brief summary of my issue. On 8/2/23, while in the process of a lane change, my vehicle goes into limp mode, and I am almost rear-ended by a large Ford truck! I immediately look at the dash and see it is displaying "Park" and I switch it to "Drive". My vehicle picks up speed, and accident has been avoided. On 8/8, I left my home and went approximately 10 minutes away. I was in the store for about 15 minutes. When I walked up to the vehicle, I noticed that I had to use my key to unlock the door, which wasn't common nor did the side mirrors automatically unfold. Once inside the vehicle, every time I attempted to start the vehicle it would hesitate and turn-off immediately. Eventually I was able to get it started, so I put it in reverse. After moving 2-3 feet, it completely shut down while blocking several parking spots. My vehicle started, but by this time, the vehicle has been inoperable for approximately 45 minutes in 95-degree weather! I then contacted Genesis Roadside Assistance and arranged for the vehicle to be towed to Dick Smith Hyundai in Greenville, SC. 8/26 - My son was approximately an hour away in the vehicle, and it broke down. Since the dealership informed me that it was a battery issue, my son attempted to jump the vehicle off. The vehicle had to be towed. 9/6, I was taking a right out of the parking lot, once I got midway in the road (not completing my turn), I heard a grinding noise, the dash switched to park, and speed rapidly decreased. At the same time, the traffic that was halted by a red light is now rapidly approaching. I informed my daughter to brace herself, as I slowly prayed and rolled to the medium. The technicians has informed me that the vehicle is unsafe to drive. They kept the vehicle a month. I get it this week and it breaks down 4 times. I was almost hit when it broke down between 2 lanes.

"What component or system failed or malfunctioned? Is it available for inspection upon request? Vehicle turned off in the middle of the road, warning it was hot How was your safety or the safety of others put at risk? The vehicle was driving on the highway and suddenly turned off without warning Has the problem been reproduced or confirmed by an independent dealer or service center? Yeah Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Only because of the dealer and they have no remedy Were there warning lights, messages or other symptoms of the problem before the failure and when did they first appear? No

Car randomly will cut off at slow speeds and when entering roadways fails to accelerate at a sufficient pace with traffic (can put pedal to floor and doesn't accelerate). Have contacted dealer several times, told earliest available to get in for service is two months and they will not order replacement fuel pump/fuel cell till the car is dropped off, and replacement part takes four to six weeks to be delivered.

The fuel pump malfunctioned while driving 70 mph on the interstate. When the car shuts off, all the dashboard lights come on. Then the car does not allow you to accelerate. My husband and i almost lost our lives. Thankfully there was a shoulder on the left lane coming in from Louisiana to Texas. The car shut off 10+ times within an hour time span on the way home. My family’s safety was constantly at risk, so we immediately brought the vehicle to a Genesis dealership in Houston Tuesday August 8, 2023. It is now 9/21/23, and the fuel pump has not arrived yet because it is on back order.

Car stopped running while on the interstate. Could have crashed into others or others crashed into me. Mechanic confirmed it’s a bad fuel pump. 10 other Genesis GV80 in the shop for the same reason. No parts available.

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.

Engine had first incident not turning in one morning and check engine light showing up. Vehicle had to be towed to neares dealer for repair. They stated there was a dirty coil and that problem was resolved. Two days later check engine e light again came back on and vehicle engine would rattle and stall. Dealer stated it was bad fuel to wait a few days. Took back to retailer this time the states there was a malfunctioning fuel injector that was replaced. 1 week later engine stalled in middle of busy main avenue in town and once again had to be towed to dealer for repair: vehicle has been at dealer since October 28 ,2022. They have replicated the problem and still can’t fix the problem have been without a vehicle for 3 months now. No loaner or rental car provided. Ci tasted manufacturer and still no remedy. Please investigate.

My GV80 has been randomly shutting down at low RPMs for the past 8 weeks this happens WHEN I AM DRIVING and this is happening to other GV80 owners per my service manager I spoke to yesterday. I need a new fuel pump to fix the issue but they are on back order so I am left to drive a VERY UNSAFE VEHICLE until they get this part in. This issue does not show up with any diagnostic tools (autel, global, etc) no check engine lights ever come on and my connected car health always show healthy but my car has literally shutdown on the interstate and in the middle of many roads it is horrifying and the service manager told me ONE of his customers told him he only drives in the right lane now so he can pull off quickly when his GV80 dies. This is a much bigger and more dangerous issue please look into it!

The vehicle has an issue stalling while in operation. The vehicle is not safe, especially when the vehicle stalls while operating in traffic. The issue puts many drivers and passengers at risk while operating on a roadway. The vehicle stalled in the following scenarios: entering a freeway, vehicle became unresponsive, but resumed power; entering traffic on an arterial roadway, but resumed power; turning at an intersection on an arterial roadway, vehicle lost power, vehicle became unresponsive and had to coast to a stop to be restarted; driving on a freeway at 70mph, vehicle became unresponsive and had to coast to a stop to be restarted; driving on an arterial roadway at 40mph, where vehicle became unresponsive and had to coast to a stop on a side street to be restarted. Retailer dealership was able to replicate the issue "three times", per the dealership, but did not get an error code or trouble code to fix the issue. On two occasions, dealership refused to address the issue further until a trouble or error code could be found. Dealership refused to keep the vehicle and to provide a loaner vehicle, despite validating that an issue existed with this vehicle and at least four other Genesis GV80 vehicles in Arizona. On August 22, 2022, dealership indicated that they would replace the high pressure fuel pump, which was an issue in the 2021 GV80 that resulted in a recall.

The engine stalls as if it's not receiving fuel. It has stalled on the open highway and when pulling off from a stop. The vehicle has completely shutoff several times in the middle of traffic at the stop light or entering the highway.
