What is the 2019-2023 Genesis G70 High-Pressure Fuel Pump Failure Causing Power Loss (Recall 24V-528 / 023G)?
The fuel control valve inside the high-pressure fuel pump (HPFP) can stick or allow excess fuel into the system, producing an air/fuel mixture that runs too rich. This causes a reduction or loss of motive power at low speeds, rough running, and check-engine warnings — increasing… Repairs typically run $0-$900. Severity: high.
What is the 2019-2024 Genesis G70 Electronic Parking Brake (EPB) Actuator Failure — Won't Release or Engage?
The rear electronic parking brake actuator (rear caliper motor) can fail electrically or mechanically, leaving the EPB stuck engaged (car won't move) or refusing to set. Owners report a persistent 'Push EPB Switch' warning with a blinking EPB indicator, sometimes surfacing when t… Repairs typically run $600-$1,500. Severity: medium.
What is the 2019-2023 Genesis G70 3.3T Oil Consumption with Smoke and Fouled Plugs?
Some 3.3T owners report elevated engine-oil consumption — in one documented case roughly 2 quarts over a ~320-mile trip, accompanied by bluish exhaust smoke indicating oil burning. The consumed oil contributes to heavy intake-valve carbon (the 3.3T is direct-injected), sooty/wet… Repairs typically run $300-$1,500. Severity: medium.
What is the 2019-2026 Genesis G70 Front Brake Rotor Warping / Pulsation (Brembo Pad Deposit and Early Warping)?
G70 owners frequently report a steering-wheel and brake-pedal pulsation that feels like warped rotors, sometimes appearing at very low mileage (reports as early as ~7,000-11,000 miles) and even all four rotors at once. On Brembo-equipped cars the cause is often uneven friction-ma… Repairs typically run $0-$1,200. Severity: medium.
What is the 2019-2024 Genesis G70 GDI Intake-Valve Carbon Buildup (Misfires, Rough Idle)?
Like most gasoline direct-injection engines without supplemental port injection, the G70's 2.0T and 3.3T accumulate carbon on the backs of the intake valves over time because no fuel washes them. Owners report heavy valve coking by ~24,000 miles in some cases, especially when com… Repairs typically run $400-$900. Severity: medium.
What is the 2019-2026 Genesis G70 Headlight Condensation and Moisture Causing Lighting Failure?
Moisture inside the headlamp assembly is one of the most widely reported G70 complaints across all model years. The vented housings draw in humid air, and when the internal seal or desiccant fails, water streaks, large droplets, or pooling collect in the housing. Persistent water… Repairs typically run $0-$1,600. Severity: medium.
What is the 2019-2025 Genesis G70 Parasitic Battery Drain / Dead 12V Battery?
G70 owners report the 12V battery going dead, sometimes overnight or after the car sits a few days, leaving the vehicle unable to start. Beyond normal battery aging, a recurring cause is parasitic draw — modules not fully going to sleep. The head unit/infotainment has been identi… Repairs typically run $200-$600. Severity: medium.
What is the 2023 Genesis G70 Torque Converter Internal Rivet Damage — Scratching Noise / Low-Speed Stall (Campaign T27G)?
Certain 2023 G70 2.0T models built between April 14, 2022 and June 14, 2022 can suffer internal rivet damage and cracks inside the torque converter. Symptoms are a scratching/grinding noise and, in rare cases, an engine stall at idle or creep speeds, and the fault can set a torqu… Repairs typically run $0-$1,800. Severity: medium.
What is the 2019-2026 Genesis G70 Limited-Slip Differential Chatter Noise?
G70 models equipped with the mechanical limited-slip differential can produce a chattering or clunking noise during low-speed tight turns, such as parking lot maneuvers. The LSD clutch packs require specific friction modifier in the gear oil to operate smoothly. Repairs typically run $100-$300. Severity: low.
What is the 2019-2024 Genesis G70 Power-Folding Mirror Failure (Clicking / Not Folding or Unfolding)?
As G70s age, the power-folding side mirrors develop a clicking noise and fail to fold or unfold reliably — commonly the passenger mirror not unfolding on unlock, or a mirror that won't latch into the deployed position and drifts back from wind while driving. The usual cause is wo… Repairs typically run $80-$600. Severity: low.
What is the 2019-2026 Genesis G70 Soft Clear Coat — Easy Chipping, Peeling and Swirl Marks?
Owners across Genesis models, including the G70, report unusually soft paint and clear coat. The clear coat scratches and swirls very easily (even careful washing can mar it), the front end picks up many rock chips in only a few thousand miles, and some cars develop clear-coat bu… Repairs typically run $200-$2,500. Severity: low.
What is the 2019-2024 Genesis G70 Sunroof / Headliner Rattle and Creaking Noise?
A rattle, creak, or crackling sound (often described like squeezing a plastic bottle) coming from the sunroof area or front headliner is a common G70 complaint, frequently emerging after only a few thousand miles. The noise is often worse in hot weather (around 80F+), over bumps… Repairs typically run $0-$400. Severity: low.
What is the 2019-2026 Genesis G70 8-Speed Automatic Shift Quality Issues?
The 8-speed automatic transmission in the G70 can exhibit rough or delayed shifts, particularly the 1-2 and 2-3 upshifts during cold operation. The adaptive transmission control module sometimes hunts between gears during light throttle city driving. Repairs typically run $100-$500. Severity: low.
