What owners say about the electrical system

Verbatim from NHTSA complaints, newest first
“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…”

“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 manufacturer was notified of the failure. The contact referenced NHTSA Campaign Number: 24V107000 (Electrical System) and 24V191000 (Engine and Engine Cooling) as possible causes for the failure. 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.”

“My 2017 Genesis G80 3.8L, VIN [XXX], has approximately 43,840 miles and intermittently slips or shifts improperly between approximately third and fifth gears while driving and causes harsh jolts forward. Jenkins Genesis confirmed the condition, stated that the transmission was slipping from the 3–5 clutch area, and recommended complete transmission replacement. The malfunction is unpredictable and creates a risk of sudden loss or interruption of propulsion while merging, crossing an intersection, changing lanes or driving at highway speed. A driver may press the accelerator but not receive the expected forward power. A [XXX] infant is regularly transported in the vehicle. The vehicle also has a faulty right-front ABS wheel-speed sensor, a passenger seat-belt safety-system communication fault, and intermittent electrical or sensor warnings. Genesis TSB 21-AT-010HG-1 applies specifically to the 2017 G80 and addresses shift flare or harsh shifting during the 2–3, 3–4 and 4–5 shifts. It requires transmission-solenoid, wiring-harness and fluid inspection procedures. TSB 19-AT-014HG also addresses harsh or delayed shifting in 2017–2018 G80 vehicles and provides…”
