Hyundai Ioniq2021

Known issues

• DCT (8-speed dual-clutch) transmission occasionally exhibits judder or hesitation during low-speed manoeuvres or stop-start traffic, particularly when switching between electric and petrol power
• Battery degradation over time; some owners report 5-10% capacity loss after 4-5 years, affecting electric-only range
• Charging port connector corrosion or intermittent contact issues in damp Irish climate conditions
• 12V auxiliary battery drain when vehicle is parked for extended periods; some units have failed prematurely
• Software glitches causing hybrid system to default to petrol-only mode, bypassing electric power even with charged battery
• Engine carbon build-up on direct injection fuel system, more pronounced if short trips dominate without full battery depletion cycles

Good for

• Low-emissions driving in urban areas and city centres with regular home/workplace charging
• Commuters with predictable daily mileage under 50 km who can charge overnight
• Smooth, efficient motorway cruising when running on hybrid mode with a charged battery
• Grant eligibility: 2021 models still qualify for VRT relief and SEAI supports in Ireland if purchased secondhand before emissions threshold
