On the 2018-2023 Kia Stinger 3.3L Twin-Turbo V6, nHTSA recall 24V169000 (Kia SC300) covers certain 2018-2023 Stinger vehicles with the 3.3L turbocharged engine. The left turbocharger oil-feed pipe and hose assembly can deteriorate and leak oil onto hot exhaust components, increasing fire risk.

Common Symptoms

  • Burning-oil odor or smoke from the engine compartment
  • Visible oil leakage near the left turbocharger

How to Fix

Check the VIN for recall 24V169000/SC300. If burning oil, smoke or active leakage appears, stop safely and arrange service. A Kia dealer replaces the left turbocharger oil-feed pipe and hose assembly free of charge. Do not infer P0234/P0299, turbocharger damage or a need for generic gaskets or a boost gauge from this recall.

On the 2018-2023 Kia Stinger, all turbocharged GDI engines in the Stinger (3.3T, 2.5T, 2.0T) develop carbon deposits on the intake valves over time because GDI fuel injection sprays fuel directly into the combustion chamber rather than onto the valve stems. Without port injection washing the valves, carbon accumulates and restricts airflow, causing rough idle, misfires, and power loss. This typically becomes noticeable between 40,000-80,000 miles.

Common Symptoms

  • Rough idle that worsens over time
  • Hesitation during acceleration
  • Misfires and check engine light (P0300-P0306)
  • Decreased fuel economy
  • Loss of power compared to when new

How to Fix

Walnut shell blasting of intake valves is the most effective treatment ($400-700 at a shop). CRC GDI IVD Intake Valve Cleaner (#05319) can slow buildup between cleanings. Some owners use catch cans (Mishimoto part #MMBCC-KS-18 for Stinger) to reduce oil vapor reaching the intake. Preventive walnut blasting every 40,000-50,000 miles is recommended.

On the 2018-2023 Kia Stinger 3.3L twin-turbo Lambda II V6 (T-GDI), the engine oil pressure switch on the Lambda II 3.3T is prone to seeping/leaking. Owners commonly see the oil-pressure warning light flicker at a warm idle and go out when RPM rises (classic bad-switch behavior, not a failing pump), and leaking oil onto hot components can cause a burning oil smell. It commonly sets DTC P0521. The switch sits deep in the engine valley under the intake manifold, so replacing this cheap part is labor-intensive.

Common Symptoms

  • Oil-pressure warning light flickers at warm idle, clears when revved
  • Burning oil smell
  • Oil seepage near the intake valley

How to Fix

Replace the oil pressure switch. Because the upper intake manifold must come off for access, shops typically renew the intake/surge-tank gaskets and injector seals at the same time; the part is inexpensive but 3-4+ hours of labor drives the cost. A Kia TSB (ENG237-family) covers the leaking-switch failure mode on Lambda V6 engines.

On the 2018-2023 Kia Stinger, the Stinger is widely reported to develop interior rattles, particularly from the dashboard, A-pillar trims, and door panels. The rattles originate from plastic clips losing tension and trim panels not being adequately secured from the factory. The issue is more noticeable in cold weather when plastic contracts. While not a safety issue, it is a common quality complaint for a premium sports sedan.

Common Symptoms

  • Buzzing or rattling from dashboard on rough roads
  • A-pillar trim rattles over bumps
  • Door panel creaking
  • Rear deck/parcel shelf rattle
  • Rattles worse in cold weather

How to Fix

Identify rattle source by pressing on trim panels while driving (have a passenger do this). Apply felt tape or foam strips behind loose trim clips ($10-30 DIY). Dealer may apply Kia anti-squeak tape under warranty. A-pillar rattle: remove trim, add foam padding behind clip points. Dashboard rattle: often the center speaker grille or instrument hood. Parcel shelf: add felt strips at contact points.

Owner tips & cautions

  • Tip3M felt tape (part #08612) applied behind trim clips eliminates most dashboard and A-pillar rattles. Inexpensive and easy DIY fix

On the 2018-2023 Kia Stinger, a very widely reported complaint (a single forum thread runs 45+ pages) is a popping, creaking, or rattling noise from the panoramic sunroof area. The mechanism is metal-on-metal contact where a protrusion on the glass rail bumps the sunroof housing; the noise is worst after heat-soak followed by A/C cooling because of expansion/contraction. Dealers often cannot permanently fix it, and the same design affects related Kia/Genesis models.

Common Symptoms

  • Popping/creaking from roof over bumps
  • Rattle worse after sun heat-soak then A/C
  • Metal-on-metal tick near sunroof

How to Fix

Apply foam/felt padding between the rail protrusion and housing, or lubricate the seals with Krytox-type grease (documented DIY fixes); pressing the headliner where it meets the opening resolves a plastic-crinkle variant. Dealer attempts (shimming/adjusting the glass) have mixed success; one owner needed a full sunroof replacement. No formal recall exists.

On the 2018-2023 Kia Stinger, the 8-speed wet dual-clutch transmission in the Stinger exhibits harsh low-speed shifts, delayed response when pulling away from stops, and occasional gear hunting on hills. The DCT clutch pack adapts over time but the adaptive learning can drift, leading to rough shifts. TCU software updates have improved shift quality. In rare cases, clutch pack replacement is needed.

Common Symptoms

  • Jerky or harsh shifts at low speeds (1st to 2nd, 2nd to 3rd)
  • Delayed engagement when pulling away from a stop
  • Transmission gear hunting on inclines
  • Shudder during low-speed creeping in traffic
  • High RPMs before upshift during normal driving

How to Fix

Have dealer perform TCU software update with latest calibration. A TCU reset (battery disconnect for 30 minutes, then re-learn drive) can recalibrate shift points. DCT fluid change at 30,000-mile intervals with Kia DCT fluid. For severe cases, clutch pack replacement under warranty ($2,000-4,000).

Owner tips & cautions

  • TipAfter a TCU update, the transmission needs 200-300 miles of mixed driving to fully re-learn your driving style. Give it time before judging the results
  • TipChange DCT fluid every 30,000 miles. Many owners report noticeably smoother shifts after a fluid change with fresh Kia DCT fluid
Typical repair cost:$0 - $4,000

On the 2018-2023 Kia Stinger, owners widely report brake-pedal and steering-wheel pulsation under braking, especially on GT (3.3T) cars. The root cause is usually uneven pad-material transfer (friction deposits) from the soft OEM pads glazing onto the rotors when hot, rather than true warping. Resurfacing/replacing rotors without changing pads brings the problem back.

Common Symptoms

  • Pulsation/vibration through brake pedal when stopping
  • Steering-wheel shimmy under braking
  • Vibration felt at highway-speed braking
  • Rapid pad/rotor wear

How to Fix

Replace front rotors AND pads together (Kia has covered this under the 12-month/12,000-mile brake warranty for some owners). Many owners permanently resolve it by re-bedding the brakes or switching to higher-quality aftermarket pads (e.g. Hawk) with a proper bedding-in procedure.
