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.
