Oil leaking onto the exhaust manifold increases the risk of a fire.
The manufacturer has issued service bulletins covering engine 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.
Certain 17-18MY Genesis G80 (DH) vehicles may exceed evaporative emissions standards due to Onboard Refueling Vapor Recovery (ORVR) system. To correct this symptom, an auxiliary canister assembly between the canister and Canister Close Valve (CCV) will be installed.

Owners of the 2018 Genesis G80 describe multiple engine failures across this 11-complaint cluster. The turbo oil supply pipe leak appears most frequently—white smoke from under the hood, oil dripping onto the hot exhaust manifold, and fire risk. Two owners report the leak recurred after a 2019–2020 recall repair; one was denied warranty coverage and told to pay out of pocket. Genesis and NHTSA campaigns 24V191000 and 19V538000 address this issue, but parts remain unavailable months after recall issuance, forcing owners to park outside.
Separate reports detail engine knocking with hesitation and a check engine light at 38,500 miles, engine stalling during normal driving that requires full shutdown to restart, and intermittent oil pressure warnings at low RPMs—mostly blamed on a faulty sensor, though owners worry a sensor warning could mask real problems.
One owner reported overheating and alarm at 49,000 miles after routine dealer service. The oil pressure light false alarms appear cold-weather related (below 55 degrees) and are described as expensive to diagnose. No owners report successful repairs for the knock, stall, or pressure sensor issues; some have not yet brought vehicles to dealers.
Turbo oil feed pipe or turbo charger oil supply pipe develops seal failure or leak, allowing hot oil to drip onto the exhaust manifold. Results in white smoke from under hood, fire hazard.
When: 43,628 to 45,000 miles; some cases occurring after prior recall repair (2019-2020)
Symptoms owners cite: White smoke from underneath hood; Burning smell from engine
Repairs/costs cited: Left side or turbo charger oil supply pipe replacement. One owner reported paying out of pocket after prior recall repair in 2020.
Recalls/TSBs owners mention: NHTSA Campaign 19V538000 (Engine and Engine Cooling) completed in 2020 for oil supply pipe leak; Campaign 24V191000 (Engine and Engine Cooling) issued but parts unavailable as of complaint filing. Owner reports Genesis refusing warranty coverage for recurrence.
Engine overheats during normal driving, triggering alarm. Vehicle able to restart initially but subsequently towed to dealer. Condition reported after recent service.
When: 49,000 miles
Symptoms owners cite: Alarm followed by engine overheating
Recalls/TSBs owners mention: NHTSA Campaign 24V191000 (Engine and Engine Cooling) and 24V107000 (Electrical System) issued; parts not available for recall repair at time of complaint.
Knocking sound from under hood near engine, accompanied by engine hesitation during idling and at various speeds. Check engine warning light illuminates.
When: 38,500 miles
Symptoms owners cite: Knocking sound from underneath hood near engine; Engine hesitation while idling or driving at various speeds; Check engine warning light illuminated
Engine stalls and vehicle shuts off involuntarily during driving. Requires placing vehicle in park and completely shutting down before restart. Precedes stall with engine slowing then speeding before stopping.
Symptoms owners cite: Engine stalls and vehicle shuts off while driving regardless of conditions; Engine slows then speeds up before stopping; Vehicle lunges forward when placed in park; Front sensor warning goes off without vehicle in front
Oil pressure warning light illuminates intermittently at low RPMs, then extinguishes at higher RPMs or speeds. Owners suspect faulty oil pressure sensor. Light obscures visibility of other potential warning issues.
When: 72,200 miles and unspecified mileage; occurs below 55 degrees Fahrenheit
Symptoms owners cite: Check Oil and Low Oil warning light illuminates while idling; Oil pressure light comes on at low RPMs; Light turns off at higher RPMs and speeds; Warning light persists in cold temperatures below 55 degrees
Repairs/costs cited: Owners report faulty oil pressure sensor suspected; described as very expensive repair.
