The third-generation Tucson TL was a huge sales success in Europe, and the 1.7 CRDi diesel was the most popular engine choice. The D4FD engine is reasonably robust for a modern diesel, but it demands regular motorway driving to keep the emissions system healthy. Available with a 6-speed manual (115 hp) or 7-speed DCT automatic (141 hp), the manual is the more reliable option.
5-year warranty, strong resale
Economical and refined diesel
DPF clogs on short trips
DCT gearbox reliability concerns
Buy if: You do regular motorway driving, prefer a manual gearbox, and want a well-equipped compact SUV with strong warranty support.
Avoid if: You drive mostly short urban trips or the car has a DCT gearbox with unverified service history.
Expected Annual Maintenance Costs
Common Problems
Diesel particulate filter blocks when regeneration cycles cannot complete during short urban drives · more· less
The 1.7 CRDi requires active DPF regeneration every 300-500 km, which needs approximately 20 minutes of sustained driving at 60+ km/h. If the car is used predominantly for short urban trips, the regeneration cycle cannot complete, causing progressive soot buildup. Symptoms include the DPF warning light, reduced power, increased fuel consumption, and eventually limp mode. Forum reports show DPF warnings appearing as early as 30,000 km on cars used mainly in city traffic. Professional DPF cleaning using a forced regeneration costs €200-400. If the filter is too heavily clogged, replacement costs €800-1,800 depending on OEM or aftermarket parts. Aftermarket DPF filters start from around €350, while OEM units can reach €1,200-1,500. Prevention is straightforward: a 30-minute motorway drive every 300-500 km allows the system to self-clean.
DMF has limited lifespan due to high low-rpm torque output of the D4FD engine · more· less
The 1.7 CRDi develops maximum torque from just 1,250 rpm, which places significant stress on the dual mass flywheel and clutch assembly. The DMF absorbs torsional vibrations and has a finite lifespan, typically showing wear between 80,000-130,000 km depending on driving style. Symptoms include rattling at idle, vibrations when pulling away, clutch slippage, and a high biting point. Some owners have reported premature failures as early as 30,000 km on DCT-equipped models. A combined clutch and DMF replacement costs approximately €900-1,600 including labour at an independent garage. Hyundai dealers charge more, typically €1,200-1,800. The DMF alone costs around €400-700 as a part. Urban stop-start driving accelerates wear significantly.
Carbon deposits clog the EGR valve, causing rough running and reduced power · more· less
The exhaust gas recirculation valve on the D4FD engine progressively accumulates carbon deposits, particularly on cars driven mostly in urban traffic at low engine temperatures. Symptoms include rough idle, hesitation under acceleration, reduced power, increased fuel consumption, and eventually the check engine light. The EGR valve on the 1.7 CRDi is positioned under the turbo manifold and is difficult to access, requiring approximately 5-6 hours of labour for replacement. Cleaning the EGR valve costs €200-350 and can resolve the issue temporarily. Full replacement including labour runs €400-800. A professional EGR cleaning every 50,000-60,000 km is recommended as preventive maintenance once outside warranty.
Dry-clutch DCT suffers from shudder, jerky shifts, and premature clutch wear in stop-start traffic · more· less
The 7-speed dual-clutch transmission (D7UF1) paired with the 141 hp version uses a dry-clutch design that is sensitive to urban driving conditions. Common symptoms include judder in first gear, slipping with jerky shifts in higher gears, hesitation from standstill, and metallic noises during gear changes. Hyundai issued a TSB for DCT clutch judder diagnosis and TCU software updates, but this does not fully resolve the underlying hardware wear. Clutch pack replacement costs €1,200-2,000 at a dealer, while a full transmission replacement runs €2,500-3,000. The 6-speed manual gearbox in the 115 hp version is robust and does not suffer from these problems. This issue only applies to DCT-equipped models.
Variable geometry turbo actuator sticks from carbon buildup, causing limp mode · more· less
The D4FD uses a variable geometry turbocharger (VGT) whose actuator mechanism can stick due to carbon deposits building up on the vane mechanism. This typically occurs on cars driven gently at low RPM for extended periods. Symptoms include sudden loss of boost, limp mode with the engine limited to around 2,500-3,000 rpm, and fault codes P0299 (underboost) or P2563 (turbo actuator). In some cases, cleaning the actuator mechanism and updating the ECU software resolves the issue for €300-500. If the turbo internals are damaged, replacement costs €800-1,500 at an independent specialist. Regular motorway driving and occasional higher-rpm use helps prevent carbon buildup on the VGT mechanism.
Steering becomes sticky or heavy at various speeds due to MDPS coupling or sensor failure · more· less
Some Tucson TL owners report intermittent power steering issues where the steering feels sticky, notchy, or heavy at certain speeds. The root cause is typically a dried-out universal joint coupling in the steering column or a faulty torque sensor in the MDPS module. Hyundai released a TSB for the MDPS coupling replacement involving application of special grease. The coupling replacement costs approximately €200-400 including labour. If the MDPS module itself needs replacement, costs rise to €600-1,000. While not extremely common, the issue can be alarming when it occurs at highway speeds.
Reliable if driven regularly on motorways, problematic for city-only use
The Hyundai Tucson TL 1.7 CRDi is a solid choice if the driving profile matches the engine's needs. The D4FD diesel has no catastrophic design flaws (unlike its NX4 successor), and the timing chain is long-lived (250,000+ km). However, like most modern diesels, it depends on regular motorway driving to keep the DPF, EGR, and turbo healthy. Cars with DCT gearboxes carry additional risk. Manual gearbox versions with documented motorway use and complete service history are the safest buy.
Recalls and Technical Service Bulletins
ABS module (HECU) internal corrosion causing fire risk (2016-2020 models, recall 11DC03)
Critical - verify completed
Secondary hood latch failure (May 2015 - March 2016 production)
Verify completed
DCT software update for clutch judder (DCT-equipped models)
Verify if applicable
Trailer hitch wiring harness malfunction (May 2015 - November 2016 production)
Verify if applicable
Contact Hyundai with the VIN to verify all recalls and technical service bulletins have been completed. The ABS/HECU fire risk recall is the most critical and affects a large number of Tucson TL vehicles produced between 2016 and 2020.
Warranty Status
Factory warranty (5 years / unlimited km)
Expired on 2015-2020 models
Rust perforation warranty (12 years)
May still apply on 2015-2020 models
Extended warranty
Available through Hyundai dealers
All Tucson TL models (2015-2020) are now beyond Hyundai's 5-year factory warranty. The 12-year rust perforation warranty may still apply to later models. An extended warranty is available through Hyundai dealers and can be worthwhile given the diesel-specific maintenance requirements.
