The failure pattern owners describe
Owners report widespread electrical failures across the 2011 Genesis electrical system. The most severe issue is wiring harness insulation failure: one owner experienced melted and charred wires in the passenger-side harness that produced smoke, disabled transmission engagement, and triggered reverse lights that wouldn't turn off—the vehicle was declared a total loss. Another owner reported the coolant fan connector melting in 2019, linked to ECM issues, despite a prior ECM recall that allegedly didn't address the root problem.
Intermittent headlight flickering when the turn signal is engaged occurs 15–20% of the time when headlights are set to 'ON' (not 'AUTO'), with one owner noting weeks or months between incidents. Multiple owners report unexplained engine stalls at highway speeds and during reversing—dealers found no diagnostic codes and could not replicate the failures. Starting problems manifest as slow starts or clicking with no start at all.
Brake and tail light failures are frequent, with some attributed to diode failure or switch defects. Owners also report dashboard lights flashing when the vehicle gets wet, with loss of brake pedal interlock preventing normal gear engagement. One parked vehicle caught fire in the engine bay. Infotainment issues include Bluetooth randomly disconnecting and navigation screens freezing repeatedly. A 53,000-mile vehicle had drive belt failure causing loss of power steering and climate control; Hyundai denied warranty coverage.

Failure modes owners describe
Wiring harness insulation failure and fire
Wires in the harness along passenger front and rear developed melted and charred insulation, exposing wires that contacted each other. Led to smoke, electrical burning smell, loss of functionality, and vehicle declared total loss.
When: Intermittent failures over time before catastrophic failure
Symptoms owners cite: Interior lights failing intermittently; License plate light blowing out; Wisp of smoke followed by cabin filled with burning electrical smell; Vehicle would not go in gear; Dashboard warnings appeared; Reverse lights came on and would not turn off
Repairs/costs cited: Shop found melted and charred wires in passenger front and rear wiring harness; vehicle declared total loss by insurer (GEICO) because root cause unknown
Recalls/TSBs owners mention: Recall 13V113000 (04/01/13) addressed exterior lighting brake light switch but did not prevent subsequent wiring harness failure
ECM-related coolant fan connector melting
Coolant fan controller shorted out, causing the connector to melt. Preceded by 2016 engine shutdown event and ECM recall that did not address the underlying issue.
When: 2019, at 23,000+ miles on vehicle; related to 2016 incident
Symptoms owners cite: Engine light came on while driving; Coolant fan connector melted; Engine light returned after thermostat and sensor replacement
Repairs/costs cited: Dealer initially misdiagnosed as thermostat, temperature sensor, coolant flush, A/C compressor, and hose replacement. Second shop identified coolant fan controller short and melted connector
Recalls/TSBs owners mention: ECM recall in March 2016 did not address the problem; owner states recall specifications did not fix the underlying issue
Headlight flickering when turn signal engaged
Headlights flicker or shut off briefly when turn signal is used, occurring intermittently (15–20% of the time or weeks to months between incidents). Only occurs when headlights set to 'ON' rather than 'AUTO'.
When: Intermittent; can occur weeks to months apart
Symptoms owners cite: Headlights flash off and back on quickly when turn signal engaged; Headlights shut off for a couple of seconds when making turns; Does not occur when headlights in 'AUTO' mode; Distracting to driver and other drivers
Recalls/TSBs owners mention: TSB 20-BE-009H exists addressing this issue
Engine stalling without warning
Vehicle stalled suddenly on highway and local driving without diagnostic codes present. One instance occurred when door opened and closed; another with no clear trigger. No root cause identified.
When: Various mileages: 80,000 miles, 147,000 miles; also during reversing
Symptoms owners cite: Vehicle stalled without warning at highway speeds; Vehicle stalled while reversing; Loss of power on highway; Stalling resolved by opening and closing driver's door in one case
Repairs/costs cited: Dealers could not find failure codes or duplicate the failure; no diagnosis or repair completed
Engine start failures and clicking
Intermittent starting problems where vehicle sometimes starts immediately, sometimes starts slowly, or does not start at all and produces clicking sounds instead.
When: Vehicle off when problem occurs; pattern ongoing
Symptoms owners cite: Starts immediately sometimes; Slow start sometimes; No start with clicking sound
Drive belt breakage causing loss of power and steering
Drive belt broke or tore out at 53,000 miles on a vehicle maintained on Hyundai service schedule. Caused steering wheel to stiffen and A/C and lights to shut off.
When: At 53,000 miles
Symptoms owners cite: Steering wheel became stiff; A/C turned off; Lights turned off
Repairs/costs cited: Dealer quoted $7,000 out of pocket for belt and engine repairs

What owners are reporting 2 most recent
The car was parked (not running or moving) in an open air grocery store parking lot. I was in the grocery store for approximately 20 minutes and came out to find a crowd and a fire crew who had just put out the fire in the hood area of my car. I have photos of the car but they are on my phone and I don't know how to send them to computer.
Noticed that the head lights shut off for a couple of seconds when making a turn onto a ramp on an interstate. Seemed to happen when the turn signal was operated and has repeated a dozen or so times since the first occurrence, but can go weeks to months between incidents. I think that the head light selections switch was set to "on" at the time as I have not noticed this to occur when set to…
