2022 Genesis GV70: sudden loss of power

Filed Oct 27, 2026 · Driver assistance, Transmission · CA

I am reporting a potentially serious transmission safety issue involving my 2022 Genesis GV70 2.5T AWD. While traveling on [XXX] through [XXX]’s Grapevine, my vehicle unexpectedly jerked and appeared to slip out of gear. Engine RPMs increased to approximately 3,500–4,000 without corresponding acceleration and remained unusually high, including while driving on level ground. No warning lights or error messages appeared. The symptoms recurred after restarting the vehicle. The vehicle subsequently experienced complete loss of propulsion and would no longer move in Drive or Reverse, despite the engine revving. Genesis Santa Monica confirmed the no-movement condition. According to repair order #XXX, technicians found transmission fluid approximately one quart low, dark brown, and burnt-smelling. They added fluid, reset adaptive values, and performed a transmission control module relearn. No diagnostic trouble codes were found, and the vehicle remained inoperable. The dealership recommended transmission replacement at an estimated cost of approximately $15,000. I am concerned that an unexpected loss of power while traveling at freeway speeds could create a serious collision risk, particularly when no warning indicators appear. I request that the federal safety agency review this incident for a possible transmission-related safety defect and determine whether similar failures are occurring in other Genesis GV70 vehicles.

The vehicle has experienced a pattern of recurring electrical failures beginning shortly after purchase, involving driver door controls (window, lock, mirror, and interior lighting functions), which have required four separate repair attempts over approximately three years, including replacement of a door module, a wiring harness, and a door switch assembly. Despite these repairs, the same driver door electrical failure has recurred multiple times. The vehicle has also experienced a seat memory module failure (module was replaced), and a persistent rear hatch malfunction that has never been resolved. The most serious concern is that the vehicle has, on multiple occasions, unexpectedly shut down while being driven, including instrument cluster and infotainment screens going dark, occurring when the automatic engine stop/start feature engages at intersections. The vehicle has restarted on its own after acceleration in some instances. Power steering assist has also been affected during at least one of these events. Most recently, the vehicle failed to start at all on one occasion, requiring roadside assistance to jump the battery; the dealer diagnosed unstable battery voltage but did not identify a root cause connecting this event to the prior shutdown incidents. This creates a significant safety risk due to potential loss of vehicle control or loss of power while operating in traffic. The problem has been reproduced and confirmed by the dealer on multiple occasions (door module and wiring harness failures were diagnosed and repaired), though the shutdown-while-driving events specifically have not been duplicated by the dealer despite multi-day testing. The vehicle has been inspected exclusively by the authorized dealer; it has not been inspected by police or independent parties. Warning symptoms (flickering door lights, dead door controls) preceded the shutdown/stall issue by roughly a year before the stalling symptom began.

My vehicle is at the Genesis dealership with what they even consider a common problem. Road debris putting a hole in the unprotected Turbo Intercooler Radiator. This is a safety issue because the loss of power in the vehicle once you lose your turbo. The radiator is very unprotected down at the bottom of the front of the vehicle and Genesis needs to do something about this. This is going to cost me $1500 to fix there not covered by Genesis even though it's a serious design flaw. I know I'm not the first person to report this, as I've seen forum posts about it and the issue is quite common. If it's so common, and it's so vulnerable, there most definitely is a design flaw in the vehicle.

The coolant system on my 2022 Genesis GV70 has repeatedly failed despite multiple repairs. On April 2, Greenway Genesis diagnosed a coolant leak and replaced several components. The problem returned, and I brought the vehicle back on April 29 because the coolant appeared low again and the engine sounded louder than before. On October 25, Holler Hyundai confirmed another coolant leak, this time involving the integrated thermal management system. The recurring coolant loss places my safety at risk because it can lead to engine overheating, sudden power loss, or engine failure while driving. The issue has been reproduced and confirmed by two separate Genesis/Hyundai service centers. However, the root cause has not been identified or corrected, and the manufacturer has not provided a permanent solution. The vehicle has been inspected multiple times by authorized dealerships, and repair invoices are available for review. Despite these failures, no coolant warning light or dashboard message ever appeared, which raises concern that a sensor or monitoring component may not be functioning correctly. There were no warnings or messages at any point before or during the coolant loss. The vehicle is currently at Greenway Genesis and is available for inspection. Based on multiple repeated failures and the absence of any warning indicators, there appears to be an unresolved defect that could create a safety hazard while the vehicle is in operation.

Car started bucking and lost power. Turned back into my neighborhood and it only went about 20mph and struggled to get back to my house. Totally shut down and I had it towed to dealership. I had about 1/8 tank of gas and no low fuel warning lights on. Dealership said it was out of gas even though gas showed 27 mikes left. I know for sure it wasn’t out of gas. I don’t feel safe driving this car. I only have 18000 miles on it.

I was on 495 southbound and the car lost power, and almost crashed. I had a recall (low-pressure fuel PumP) but the dealer is not taking me because I am not the original owner of the vehicle, I went to Fitzgerald-Hyundai Genesis Subaru of Gaithersburg, and Mr. Brett Davis turned me out. Need to know who is going to fix my problem, sincerely [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine shut off during driving on October 19th and October 21 2023. The Engine sputters and ceased while in traffic then flashed an "Engine Off!" Warning and made a grinding noise stopping. During the incident on October 21st I was in a heavily trafficked road and lost power at about 20 miles an hour, the resulting engine shut down almost got me rear ended by a vehicle moving much faster.

After getting routine maintenance done on 5/29/2023 at Courtesy Hyundai in Tampa, my vehicle stalled numerous times when running the A/C. The compressor kicks on, RPM drops and the car violently jerks before shutting off. The system will only restore if I turn the A/C off. So I assumed the issue was due to the A/C putting pressure on the vehicle. I took it back to the same dealership on 6/6/2023 and they performed a fuel sample and said there was bad gas (high water content) in the tank (even though I only use 93 octane gas from a premium gas station, Shell) and stated the fix action would be to drain the fuel and clean the injectors for $850. I declined because I didn't believe that was truly the problem and wanted a second opinion from a different Genesis dealership. About three weeks later, I was merging on the interstate going 65 miles per hour and the vehicle stalled, lost power and came to an immediate stop. Absolutely nothing worked!!! I almost got hit by multiple vehicles. I waited a few minutes before restarting and the vehicle drove like nothing was wrong. However, this problem continued several times as I was trying to get home. I did notice it was having difficulty accelerating after that. I would say this vehicle randomly stalled in moving traffic more than 10 times in a two month period. I was finally able to get a service appointment with Lakeland Genesis on August 4th. After about a week, I was notified the fuel pump is indeed bad and needs to be replaced, which is what I thought initially. The vehicle has not been repaired yet because the part is on backorder with no ETA. So I'm unsure if replacing the fuel pump is the final fix. We are part of an online GV70 forum and it seems many other owners are going through this same issue. This is extremely dangerous and someone is going to be seriously injured or killed because the vehicle stalls with no warning lights, no alerts, no error codes, no nothing.

I was driving 72mph on the Turnpike for about 30 minutes when suddenly I felt the car lose all power. The speed immediately started dropping, the RPM’s were very high. I had my foot on the gas pedal and it would not do anything. It was extremely scary being on highway with no power. I was able to make it to the next exit where I pulled into a gas station and turned the car off. I sat there for a few minutes before restarting it and when I did it seemed to reset the system. I was scared to pull over on the highway in case the vehicle wouldn’t reset and I wouldn’t be able to pull out onto the road. This is the 3rd time this vehicle has lost power. The other two times I had just started the vehicle and when I went to go there was no power. There were no warning lights and engine light that came on any of the times this has happened.

Vehicle lost power while normal driving. This happened multiple times. All dashboard lights turn on, then vehicle shut down/shut off. Had to safely pull over to shift gear into PARK, then restart vehicle. Vehicle acceleration is very poor, the more it does this. Vehicle feels like it’s not being provided fuel. On my app, vehicle show “ALL SYSTEMS NORMAL”. Purchased brand new, only 8500 highway miles.

Car has now lost power several times, including incident trying to cross multi lane road when it lost power and caused other vehicles to slam on brakes to avoid hitting me. The car lost power while merging onto interstate and vehicles had to avoid my car. It’s lost power just driving down the highway with cars swerving around me. I feel very unsafe but I need my car for work.
