On the 2020-2023 Genesis GV80, driver and front-passenger seat belt pretensioners can build excessive internal pressure and rupture upon deployment in a crash, projecting metal fragments into the cabin and injuring occupants. Genesis recalled ~65,500 vehicles across multiple models (GV80, G80, GV70, GV60), with GV80 units built July 2020 through December 2022 affected.

Common Symptoms

  • Pretensioner ruptures during crash deployment
  • Metal fragments expelled into cabin
  • Risk of serious injury during airbag/belt deployment

How to Fix

Free recall remedy: dealer installs a protective metal cap over the front pretensioners to contain any rupture. Verify VIN at NHTSA.gov under campaign 23V094; call Genesis at 855-371-9460 to schedule.

On the 2021-2024 Genesis GV80, owners report a humming, whining or howling noise from the rear differential that changes with vehicle speed and is most noticeable during steady cruise between approximately 35-75 mph. Genesis TSB 23-DS-004G (Aug 2023) and revision 23-DS-004G-1 identify an improperly torqued pinion lock nut from the factory causing incorrect ring-and-pinion mesh. Dealer first installs a repair kit (bolts + nut) and re-torques per spec; full rear differential assembly replacement is required if noise persists. The same TSB also covers 2021-2024 G80 (RG3) and 2022-2024 GV70 (JK1/JK1A) — chassis code for GV80 is JX1.

Common Symptoms

  • Whine or howl from rear of vehicle on acceleration
  • Hum that changes pitch with road speed
  • Noise unchanged when turning (distinguishes from wheel bearing)
  • Drone between 30-60 mph

How to Fix

Have dealer perform TSB 23-DS-004G inspection: install repair kit (2 bolts + 1 nut) and re-torque pinion lock nut first; replace rear differential assembly if noise persists. Repair is covered under Genesis 10yr/100k powertrain warranty - document the noise on a repair order before warranty expires.

Typical repair cost:$0 - $4,500

On the 2021-2023 Genesis GV80 3.0L Diesel I6, diesel GV80 models experience NOx aftertreatment system issues, including SCR catalyst efficiency codes and DEF quality warnings. The NOx sensor can give false readings, triggering regeneration cycles and reduced power modes.

Common Symptoms

  • DEF quality warning message
  • Reduced engine power mode
  • Frequent DPF regeneration cycles
  • Check engine light with NOx codes

How to Fix

Replace the NOx sensor and clear adaptation values. Use only manufacturer-approved DEF fluid. Update the ECU calibration for improved NOx system management. Avoid short trips that prevent the DPF from completing regeneration.

Typical repair cost:$400 - $2,000

On the 2021-2024 Genesis GV80 2.5L T-GDI Theta III (Smartstream G2.5T), theta III 2.5L T-GDI engines in GV80 JX1 (and related G80/GV70) illuminate the Check Engine light with random or specific cylinder misfire codes P0300-P0304 during cold start. Root cause is identified as ECM misfire-detection logic; Genesis issued service campaign 914G covering 2021-2024MY GV80 built 07/27/2020-03/04/2024 for a free ECM reflash.

This issue also affects: Hyundai Accent, Hyundai Elantra, Hyundai Excel

Common Symptoms

  • Check Engine Light on after cold start
  • Rough idle during warm-up
  • Brief stumble or shudder on first start of the day
  • Multi-cylinder or cylinder-specific misfire codes

How to Fix

Free dealer remedy under Service Campaign 914G / TSB 25-01-051G: ~30 minute ECM software reflash with improved misfire logic. Persistent misfire after reflash warrants coil/injector swap-test on the affected cylinder.

Typical repair cost:$0 - $0

On the 2021-2023 Genesis GV80, gV80 owners describe the HUD progressively fading from one side (an 'eclipse' moving across the projection) until 80-90% of the display is blocked, then briefly recovering. Many units intermittently fail for months before going completely dark and requiring full HUD assembly replacement. Cause is typically LCD/projector overheating or hardware failure, not the windshield.

Common Symptoms

  • HUD dims or fades from one side
  • Round dark area sweeps across HUD image
  • HUD intermittently disappears then returns
  • Eventually HUD stops projecting entirely

How to Fix

Rule out polarized sunglasses (which kill HUD visibility) and direct sun overheating of the projector. If fade persists when cool, request HUD projector module replacement under 5yr/60k bumper-to-bumper warranty; out of warranty, full unit replacement runs ~$1100-$2200 installed.

Typical repair cost:$1,100 - $2,200

Common Symptoms

  • 3D navigation display freezing
