Korea's best-selling SUV with five-year warranty
The Hyundai Tucson is one of the UK's top-selling compact SUVs, competing directly with the Nissan Qashqai and Kia Sportage. The third-generation (2015-2020) dominates the used market with strong availability, while the fourth-generation (2021+) introduces hybrid, mild-hybrid and PHEV powertrains. Hyundai's five-year unlimited-mileage warranty remains transferable, making used examples excellent value.
We track 11 known issues across the Hyundai Tucson range, including 2 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.
Found a Hyundai Tucson? Enter the reg to see which of our 11 known issues apply to that exact car, plus full MOT history and mileage checks.
JM (2004–2010) — Petrol options included the 2.0 Beta, 2.7 V6, with 2.0 CRDi on the diesel side. Our database flags 3 known issues on this generation, 1 of which are rated as safety-critical. The most significant concern is Turbo failure (£600–£1,200 to address).
TL (2010–2022) — Petrol options included the 1.6 T-GDi, with 1.6 CRDi, 1.7 CRDi, 2.0 CRDi on the diesel side. Our database flags 9 known issues on this generation, 1 of which are rated as safety-critical. The most significant concern is Parking brake failure (£400–£1,000 to address).
The electronic parking brake system on TL-generation Tucsons suffers from widespread failures across multiple components including the actuator motor, control module, and cable mechanism. MOT data shows this model fails parking brake tests at 95.7 times the national fleet average, with failures documented across all mileage ranges from 20,000 to 150,000+ miles. The system may fail to engage, disengage, or provide insufficient holding force. This represents the single most prevalent defect on this generation.
A failed parking brake creates a serious safety hazard on slopes and may result in vehicle runaway. The car will fail its MOT test. Complete system replacement can cost £800-1,500 depending on which components have failed. The vehicle should not be parked on slopes until repaired.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
The D4EA 2.0 CRDi engine in JM-generation Tucsons experiences turbocharger failure, typically manifesting as bearing wear, actuator malfunction, or compressor wheel damage. This issue commonly occurs between 80,000-180,000 miles and can result from poor oil quality, blocked oil feed lines, or actuator control problems. Failure modes include complete loss of boost pressure, excessive smoke production, and in severe cases, catastrophic turbo seizure that can damage the engine.
Turbo failure results in significant power loss and potential engine damage if metal debris enters the cylinders. Complete turbo replacement costs £600-1,500 including fitting. Continued driving with a failed turbo risks engine damage requiring rebuild. The vehicle remains driveable but with severely reduced performance.
During a test drive, check for hesitation, lack of power or unusual whining from the turbo area. Watch for blue or white smoke from the exhaust under hard acceleration. Check the oil condition and service history — turbos rely on clean oil.
The dual-clutch transmission (DCT) fitted to 1.6 T-GDi models suffers from premature clutch wear and juddering, particularly affecting urban driving conditions. The system uses two clutches alternating engagement for seamless shifts, but poor calibration and inadequate cooling leads to clutch slip and eventual failure. This issue is distinct from the broader DCT control problems but often occurs alongside them. Specialist clutch replacement typically costs £1,000-2,500.
Clutch failure results in inability to engage drive effectively, making the vehicle unreliable for daily use. Complete clutch replacement requires transmission removal and costs £1,000-2,500. The vehicle may become undriveable once clutch wear reaches critical levels.
Check each gear engages smoothly without crunching. Feel the clutch bite point — very high or very low can indicate wear. Listen for bearing noise when the clutch is depressed.
The dual-clutch transmission system experiences control module failures, software glitches, and hydraulic system problems beyond the physical clutch wear issues. Problems include hesitation during gear changes, sudden loss of drive engagement, and error codes relating to transmission control. NHTSA data shows significant complaint volumes regarding shifting problems and gear selection failures. This represents the broader DCT system reliability issues distinct from clutch wear alone.
DCT control failures can result in complete loss of drive without warning, creating dangerous situations in traffic. Repair costs range from £1,000-3,000 depending on whether software updates, control module replacement, or complete transmission replacement is required. The vehicle may become unreliable for daily use.
Test the automatic gearbox extensively in slow traffic, car parks and on hill starts. Feel for any juddering, hesitation or clunking during gear changes. Try repeated low-speed manoeuvres as this is where problems are most apparent.
The D4EA diesel engine suffers from fuel injector failures, typically caused by contamination in the fuel system or wear of the injector nozzles and seals. Failed injectors cause rough running, increased emissions, and poor fuel economy. This issue commonly affects vehicles between 80,000-180,000 miles and often requires replacement of multiple injectors simultaneously due to similar wear patterns across the engine.
Failed injectors cause poor fuel economy, increased emissions leading to MOT failure, and potential engine damage from incorrect fuelling. Individual injector replacement costs £75-200 per injector plus fitting, but multiple failures are common. Total repair costs range £300-800 depending on how many injectors require replacement.
Check for fuel smells around the engine bay and underneath the car. Look for staining or wetness around fuel lines and connections. Injector issues may cause rough running or misfires that are most noticeable at idle.

Based on 554k real DVSA MOT tests, the Hyundai Tucson fails more often than average on several items. The biggest outlier is subframe bushes or mounts worn at 276x the fleet average, followed by parking brake efficiency less than 50% of the r... (97x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Hyundai Tucson MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 10k miles) typically costs £60–£120 at an independent garage.
The bigger-ticket items to budget for include dct fluid service (£200–£300).

The Hyundai Tucson has some well-documented weak points, including 2 safety-critical issues that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable. 2017-2019 Mk3 diesels (1.7 CRDi or 2.0 CRDi) offer the best balance of proven reliability and value. For the Mk4, 2022+ models benefit from early-production fixes and may still carry remaining warranty. Avoid 2015-2016 first-year Mk3 examples and the underpowered 1.6 petrol across all years.
