said they had replaced a harness to get the door switches working properly. However the same issue has not started again. leading me to believe that was not the cause of the issue.

This problem has been occurring since i got the car and will be calling the dealer back again to express the dissatisfaction and failure to repair what they claimed to have fixed. It has already spent just under 2 months in the shop out of the 3 months that i have owned the vehicle.

monitoring system failure •Reverse and surround view camera failures •No infotainment or radio control on center stack •Windows and trunk release inoperable •All in-car electronics •On-board maintenance system warnings, random resets All off the above failures occurred without any prior indication of an issue, while vehicle was in motion and being driven on public roads with other drivers and vehicles nearby. These are repeat and reoccurring issues, first appearing at approximately 3,900mi on 01/20/2022. This vehicle is not safe to be driven. It is a danger to its driver (me) and passengers, and also all other nearby vehicles and pedestrians. It remains at Genesis of Akron, despite the inability to be repaired. On November 18, 2022 they required me to turn in the loaner I had been given and I was informed neither Genesis of Akron nor Genesis USA will provide safe transportation during the arbitration or lemon investigation period(s).
