Known issues

• DPF regeneration problems and occasional blocked filters requiring costly cleaning or replacement (€800–€1,200)
• AdBlue system faults, including faulty level sensors and heater element failures, causing warning lights and limp mode
• EGR valve carbon build-up and sticking, particularly in low-mileage driving patterns, leading to rough idle and reduced power
• Fuel injector carbon deposits and occasional injector failure on early CRDi units, causing hard starting and rough running
• Turbocharger bearing wear in higher-mileage examples (80k+), presenting as increased exhaust smoke or loss of boost
• Glow plug failures in cold climates, leading to difficult starting in winter months

Good for

• Fuel economy: genuine 45–52 MPG in real-world mixed driving with moderate highway use
• Torque delivery: strong low-end torque (320 Nm) makes the Tucson responsive in city driving and motorway cruising
• Practicality: generous boot space, good visibility, and easy-to-use infotainment system
• Resale value: strong demand for compact diesel SUVs in the Irish second-hand market
