On 5 separate incidents, on two separate days, when traveling at highway speeds, the car lost power and began to decelerate. After a moment the engine died. In each case I was able to coast onto the shoulder but this is a serious safety issue. On 6 further incidents, the car lost power and died in other circumstances, including in a driveway immediately after starting up. These cases were not as dangerous as the highway failures. Check engine light does not come on. No codes thrown. Dealer will not inspect for another month. Dealer has not yet inspected. Fuel, all fluids, all general maintenance is in good condition. Vehicle has less than 14k miles. Car is available for inspection upon request.

Rear Diff replaced three times. Multiple reports of people having the same problem.
-rear differential -risque of failure of delivering power to the wheels and stopping in the middle of traffic -yes -the component inspected by the dealer and been replaced -the only warning is a loud noise when you drive above 50 mph and it appeared in the early miles of the first 5400k
All wheel drive(AWD) warning light illuminates. 9482 miles have been driven on the vehicle. This has happened 5 times in the last week, April 25th- May 1st 2023. The vehicle was taken to the Genesis dealer on the 1st of May 2023. I was informed by the service department that several components related to the differential system and parts were ordered. Relief valve, actuator assembly, pressure sensor. I was informed that this may or may not fix the issue. Additional parts will have to be replaced. If that doesn't fix the issue the entire unit will have to be replaced. I asked if this was a safety problem and is it safe to continue driving my vehicle. The answer I received was they didn't know. There were no other signs or symptoms prior to this. As far I can tell the vehicle runs ok. I also don't know if the traction control system will malfunction while I am driving. I picked it up and drove it home and I haven't driven since. I called the Genesis hot line on May 1st 2023 and asked was if it is safe to drive the vehicle. As of May 2nd I haven't heard back from them.
After my test, here's what I found: If the cruise control is Off and you press and hold the cruise control button for more than 2 seconds, the speed limit function activates as indicated by the "Limit" indicator on the multi-function display. In this mode, if the vehicle speed exceeds the limit speed and you press on the gas, the power is immediately cut off, and you can't accelerate. If the vehicle exceeds the limit speed, a warning bell will sound, and the speed will flash and power is cut when pressing on the gas. If the cruise control is ON, and you press and keep holding the cruise control button, sometimes the car will begin to slow below the set speed and continue to slow, even after releasing the cruise control button, and sometimes the cruise control will remain engaged after releasing the button. In this scenario, if you press on the gas to accelerate, the power is cut out and nothing happens even though you are below the limit speed. To restore power, you have to press and release the cruise control button to deactivate the cruise control. It's as though the cruise control gets into a mode where it won't hold speed, and pressing on the gas does nothing. This seems like a software bug. The above scenarios only happen when the cruise control is ON. Power is always available when the cruise control indicates that it is not activated or when in "Normal" (non-limit) mode when active. It seems counterintuitive that accelerating manually by pressing on the gas is overridden when in the "Limit" mode. I don't know if this is a design feature or a flaw. The vehicle lost power several times in traffic - and at that time do not believe the cruise control was being used The dealer says they cannot ascertain the problem and have referred it to an executive higher-level
