All Known Issues

Brembo Brake Disc Friction Material Deposit Judder

ModerateBrakes

Flagship Stinger GT-S models are equipped with four-piston Brembo front brake calipers and vented discs. Under spirited driving followed by holding the car stationary on hot pads, uneven friction material transfer occurs across the rotor surfaces. Rather than true mechanical disc warping, this deposit creates thickness variation that induces severe vibration and steering wheel shudder during moderate-to-heavy braking from motorway speeds. Resolving the issue requires skimming the discs or replacing rotors and installing upgraded aftermarket or revised OE brake pads.

Est. Repair Cost: £350–£850
Warning Signs:

Noticeable steering wheel wobble or pulsation through the brake pedal when braking from 70 to 50 mph, High-pitched brake squeal at low urban speeds when applying light pedal pressure, Visible dark patchiness or heat spotting across the front rotor friction rings

What to Inspect:
  • Carry out several progressive braking tests from 60 mph on a clear straight road to feel for steering vibration or pedal pulse
  • Visually inspect the front Brembo discs through the alloy wheel spokes for grooving, lip wear, or pad deposit rings
  • Check service history records to see if the front discs and pads have been replaced under warranty or by a previous owner

Tailgate Hatch Rattle and Rubber Bump-Stop Resonance

MinorInterior & Trim

The wide rear liftback tailgate on the Stinger is prone to flexing and rattling over uneven road surfaces. The factory rubber bump stops, latch striker plate, and plastic interior trim clips can become misaligned or settle with temperature cycles. Drivers experience an irritating chattering or creaking noise from the rear boot compartment when driving over expansion joints, speed bumps, or rough asphalt. Adjusting the rubber dampers, applying felt insulation tape, or replacing latch striker components is commonly needed to restore cabin quietness.

Est. Repair Cost: £50–£180
Warning Signs:

Persistent low-frequency rattle or plastic creak emanating from the rear luggage area on uneven roads, Tailgate requires a forceful slam to engage the primary latch securely, Rub marks or paint chafing visible on the inner boot shut apertures where bump stops contact bodywork

What to Inspect:
  • Drive over road undulations or drain covers with the radio turned off and listen for chattering from the rear hatch
  • Open the tailgate and inspect the adjustable rubber bump stops for wear, missing washers, or loose thread mountings
  • Ensure the luggage compartment load cover sits firmly in its side guide channels without rattling

Buying Tips for 2018–2020 Kia Stinger

  • On 3.3 twin-turbo V6 GT-S models, check for high-speed brake judder under moderate-to-firm deceleration, caused by brake pad friction deposit buildup on the Brembo discs
  • Inspect the rear hatch tailgate alignment and bump-stop dampers for creaks, rattles, or water ingress past the rubber seals
  • Check the front bumper lower lip and front undertrays for scuffing and crack damage from steep ramps and high kerbs
  • Verify that all electronic driver assist systems (Blind Spot Detection, 360-degree camera, Lane Keep Assist) operate without warning lights
  • Inspect rear tyre inner shoulders for excessive wear, as the rear-wheel-drive camber and aggressive torque accelerate tyre consumption
