What stands out
Electrical accounts for 30% of every owner complaint on file for this vehicle — the dominant problem area across 8 categories tracked.
No new NHTSA electrical complaint has been filed on this vehicle in over 5 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Some vehicles may exhibit a loss of connectivity or interruptions in the middle of using Bluelink Service functions. This may be due to an irregular disconnection on Verizon's communication network. If you are experiencing issues with remote commands, or other Bluelink services, please see the instructions below to reestablish the connection via the AVN pinhole reset method.

The failure pattern owners describe
2017 Genesis G80 owners report recurring electrical problems with serious safety implications. The most widespread complaint is a faulty oil pressure sensor that lights up at stops and idles but clears on acceleration—Genesis already issued a recall for this in Korea but refuses to cover US vehicles, leaving owners facing $800–$1600 repair bills for a sensor costing under $200 to manufacture.
More critically, Genesis issued federal recall 24V107000 in February 2024 for an ABS module electrical short that can cause engine compartment fires while driving or parked. Yet months later, dealers lack the repair parts and cannot confirm delivery dates. Owners report conflicting guidance from Genesis about whether it's safe to drive vehicles subject to this fire-risk recall.
Beyond the oil sensor and ABS issues, owners describe complete electrical collapses—sudden loss of all power while driving (affecting steering and acceleration), spontaneous restarts 15–20 minutes later without input, and dashboard blackouts on the highway. Starter and alternator failures have also been reported, sometimes denied warranty coverage. One incident involved improperly seated battery terminals that killed all electrical power at highway speed. A few owners also mention LED headlight discoloration turning orange and impairing night visibility.
The pattern suggests systemic electrical design or manufacturing problems affecting multiple subsystems across this model year.

Failure modes owners describe
Oil pressure sensor malfunction
Oil pressure warning light illuminates at idle or deceleration, clears under acceleration. Sensor fails due to defect. Genesis issued recall in Korean market but not in US market despite widespread reports. Not covered under warranty.
When: At complete stops or deceleration; intermittently
Symptoms owners cite: Oil pressure warning light comes on at idle or slow speeds; Warning light clears when accelerating; Light comes on intermittently
Repairs/costs cited: Sensor replacement $800–$1600 at US dealerships; sensor costs less than $200 but labor-intensive due to location behind engine manifold
Recalls/TSBs owners mention: Recall issued in Korean market for 'DH' body style; no recall issued in US market

The car randomly does not turn on when I press the start button. Nothing happens. It's not the key fob either because absolutely nothing works in the car at that point. I can't open the trunk using the button inside the car, lock or unlock the doors, nothing. The car is essentially a useless hunk of metal. After about 15-20 minutes though, the car will just randomly turn on. I don't press…
