The 2022 Genesis G80 is too new for widespread high-mileage patterns, but early adopters are seeing concerning engine failures on the 2.5T (theta engine family heritage) and fuel system recalls affecting both powertrains. Most examples are still under warranty, but post-warranty owners face catastrophic repair costs.
2.5L Turbo Catastrophic Engine Failure (Theta Engine)
Occasional · high severityTypical onset: 30,000-70,000 mi
Symptoms: sudden metal-on-metal knocking, loss of oil pressure, check engine light with misfire codes, engine seizing without warning
Fix: Complete engine replacement or rebuild required. This is the Theta II/III engine family known for bearing failures and piston ring issues. Metal debris circulates through the system once bearings fail. Repair involves short block replacement minimum, often full long block. 18-25 labor hours for replacement, plus machine work if rebuilding.
Estimated cost: $8,000-15,000
Fuel Pump Failure and Fuel Line Deterioration
Common · high severitySymptoms: no-start condition, engine stalling at operating temperature, rough idle and hesitation, fuel smell in cabin or near tank, check engine light with fuel pressure codes
Fix: Multiple NHTSA recalls cover fuel pump module and fuel line deterioration. Pump failures leave you stranded; deteriorating lines are fire hazards. Fuel pump replacement requires tank drop (3-4 hours). Fuel line replacement involves running new hard lines and securing with proper clips (5-7 hours depending on extent).
Estimated cost: $800-2,200
Transmission Oil Cooler Leaks
Occasional · medium severityTypical onset: 40,000-80,000 mi
Symptoms: transmission fluid spots under vehicle, transmission overheating warning, harsh shifting when fluid level drops, pink or red fluid visible near radiator area
Fix: The 8-speed automatic's external cooler lines and cooler itself develop leaks at fittings or from internal corrosion. Requires cooler replacement and sometimes hard line replacement if corrosion has spread. Must flush entire system and refill with Genesis-spec ATF. 4-6 hours labor.
Estimated cost: $1,200-2,000
Front Seatbelt Pretensioner Malfunction
Rare · high severitySymptoms: seatbelt warning light stays on, seatbelt fails to retract properly, airbag light illuminated, clicking noise from B-pillar
Fix: Recall addresses pretensioner that may not properly restrain occupants in a crash. Dealer-only repair involves complete seatbelt retractor assembly replacement with reprogramming. Not a DIY job due to airbag system integration. 2-3 hours per side.
Estimated cost: $600-1,200
Transmission Mounts Failing Prematurely
Occasional · low severityTypical onset: 35,000-65,000 mi
Symptoms: clunking when shifting from park to drive, excessive vibration at idle, shudder during acceleration, visible movement of engine/trans assembly when revved
Fix: Hydraulic transmission mount fails early, causing drivetrain movement and harsh engagement. Requires lifting engine/trans slightly to access. OEM mount strongly recommended over aftermarket. 2.5-3.5 hours labor.
Estimated cost: $450-800
Beautiful car with luxury features, but the 2.5T engine reliability shadow and fuel system recalls make this a risky used buy without comprehensive warranty coverage — stick with CPO or the 3.8 V6 if buying private party.
