Latest G90 electrical complaints
My 2017 Genesis G90 received Safety Recall 018G (NHTSA 24V-107) on December 31, 2024, addressing a starter-solenoid electrical short/fire risk. Around June 7, 2026, I noticed an unusual odor and found the engine-room junction/fuse box extremely hot, with visible heat damage. An independent shop documented melted plastic near the starter relay/junction box, cleaned damaged material, replaced a 200A fuse, and reinstalled the relay kit. It recommended replacing the junction box, which was not done. Around August...

7-8, 2026, warning indicators and steering-related problems occurred. The vehicle was towed to Genesis Dublin August 10. Inspection identified substantial thermal damage to the junction box and wiring. The vehicle remains unrepaired at the dealership, with damaged components believed available for inspection. The vehicle was also evaluated for an insurance claim. At a September 24 walkthrough, dealership personnel confirmed that the damaged junction-box/alternator connection area overlaps the area where alternator-related connections were handled under Recall 018G (Step 6, TSB 24-01-059HG). They discussed possible alternator overcharging but said damaged wiring prevented accurate output testing. The initiating cause remains unknown. I am concerned the recall may have reduced the original starter-solenoid short/fire risk while leaving a potentially related electrical overheating hazard unresolved. The severe heat and melting posed a potential engine-compartment fire risk. I am not claiming the recall caused this failure; I request NHTSA review whether it suggests an unresolved recall-related hazard or separate electrical defect. Genesis Motor America Case 43221279. Genesis denied warranty goodwill repair based on age/mileage without providing a conclusive technical cause. An insurance inspector attributed the thermal damage to corrosion-related electrical resistance and overheating.
The contact owns a 2017 Genesis G90. The contact stated that while the vehicle was stationary, the contact became aware of smoke coming from the driver's side of the engine. While stopped at a red light, the vehicle was smoking with an oil-burning odor. Additionally, the contact stated that the air bag module light was illuminated.

The dealer and the manufacturer agreed to assist with the recall repairs but had not provided the parts for the repairs. The failure mileage was 118,000.
The centre console screen has completely failed and has gone black. Yes, the screen is available for inspection upon request. The screen houses access to most safety systems in the car, including the reverse camera, front camera, collision avoidance system settings, lane safety settings, blind spot monitoring settings etc. Lack of access to these systems makes driving the car less safe Yes, the problem has been reproduced by a Genesis dealer The dealer had the car for over 2 weeks but was unable to find any...

I own a 2024 Genesis G90 with two active NHTSA recalls: 25V474 and 25V833. On April 19, 2026, the vehicle suffered a total electrical failure: "Check brake system" warning Engine would not start Electronic door handles failed; occupants trapped inside for over 20 minutes Turn signals operate abnormally The dealer previously repaired only by reset (no recall fix). This is a life-threatening safety defect affecting brakes, electrical system, and egress. Please open an investigation and enforce recall repairs. I am pursuing Lemon Law relief.
About every 45 days the car will not turn off. Safety items like the rear view camera will not work. The main viewing screen will go dead. I called the dealership. They said this was a common problem with my car. The only fix is to attempt a full system reboot with a paper clip. This has now happened three times to me. Once the car started without me pushing the start button. Twice while I was driving.
the electrical system failed on four separate occasions. Once in heavy traffic on Route 130, NJ; anther with a young grandchild in the car. I am afraid to drive it
Since purchased as a new vehicle from dealer, the TPMS ( Tire Pressure Monitoring System ) menu has been absent from my dash as an option to choose so that I can monitor the tire pressures. The menu widget that contains the TPMS also contains other options that are suppose to be available, but also do not show and are unavailable to the driver.
Please see attached summary of this issue which has impacted safety of a large number of Genesis vehicles since 1 January 2023.
on Thursday 10/24/2024 I went to use my car which was parked in my garage and although the car was unlocked none of the doors would open. The car was completely dead and I had used it just several days before. Nothing would open doors, trunk no response from the key fob. A tow truck had to be called and the truck dragged the car out of the garage and placed dolly wheels on the front and towed from the rear to a Genesis dealer. My concern this electrical problem locked the car if a child was in the rear the only way...

to get the child out would be to break a window and then entry through the broken window as well as exit. The included metal key would not open the door and no access to the trunk or under the hood. The doors are electronic and power operated
