5.0/10
5 walk-away risks, 3 serious faults, 1 minor fault documented for this generation, weighted by severity and repair cost. Biggest factor: 2021 hecu / abs module fire recall. Score methodology.
The 2021-2025 Tucson guide has to treat 2021 as a leftover TL-generation car and 2022-2025 as the NX4 redesign, because the faults do not line up neatly. The official high-cost traps are mostly recall-driven: 2021 HECU/ABS fire risk, 2023-2024 electric oil-pump controller overheating, 2022-2024 tow-hitch harness fire risk, 2024 MDPS power-steering pack short, and 2025 connecting-rod-bolt engine recall. The owner-reported traps sit underneath those recalls: hybrid coolant loss, hybrid 6-speed lag/vibration, and European 7DCT clutch judder. The safest Tucson is a 2023-2024 NX4 2.5 petrol or 1.6 hybrid with every recall closed by VIN and no coolant, steering or transmission warning history. Owners should keep dealer recall invoices because this generation's resale value depends less on mileage and more on proving the car is not sitting inside an open fire or driveline campaign.

Engines and trims
Which Hyundai Tucson should you buy?
On most used cars, the engine and trim choice changes the risk more than the mileage does. Narrow this down before you start viewing cars.
2.0L / 2.4L petrol TL carryover
2021 US-market carryover
ACCEPTABLE ONLY AFTER HECU CHECK
The 2021 Tucson is mostly the old third-generation TL car. It does not share the NX4 hybrid story, but it does carry the HECU/ABS fire recall risk. Buy it like an older Hyundai: recall status, underbody condition, oil history and ordinary automatic-transmission behaviour matter more than screen size.
Smartstream 2.5L GDI/MPI petrol with 8-speed automatic
2022-2025 NX4, market-dependent
BEST MAINSTREAM CHOICE
The 2.5/8AT Tucson avoids hybrid coolant and 6-speed hybrid driveline concerns, but it still sits inside recall populations for electric oil pump controller, tow-hitch harness, MDPS and some 2025 engine-build issues. A recall-clean 2.5 is the easiest NX4 Tucson to recommend.
1.6L T-GDi hybrid / plug-in hybrid with 6-speed automatic
2022-2025 NX4
GOOD IF COOLANT AND DRIVE FEEL ARE CLEAN
The hybrid Tucson is quick, efficient and more refined than the petrol 2.5, but buyer risk shifts to coolant circuits, hybrid warnings and transmission/clutch control. The inspection must include both reservoirs, a cold pull-away test and a module scan beyond generic OBD.
1.6 T-GDi / 1.6 CRDi with 7-speed DCT
2021-2025 Europe and other non-US markets
MARKET-SPECIFIC INSPECT CAREFULLY
The 7DCT row is irrelevant to many US Tucsons but very relevant in Europe. Low-speed clutch judder, reverse hesitation and adaptation issues appear in owner evidence. Verify the gearbox by VIN before applying this fault.
Year notes
Year-by-year buyer advice
Use this to narrow the search before you spend time travelling to view a car.
2021
Final TL-generation Tucson in the US, mostly 2.0/2.4 petrol and 6-speed automatic. HECU/ABS fire recall is the headline official risk.
Buyer: Confirm whether the car is TL or early NX4 market spec, then run the HECU recall before viewing. Do not let cheap pricing distract from fire-recall status.
Owner: If recall 195/20V543 applies, finish it and keep the invoice; the old-generation Tucson now competes mainly on trust and condition.
2022
NX4 redesign arrives in many markets with 2.5 petrol, 1.6 hybrid/PHEV and dramatic new bodywork. Early cars carry launch-year trim/software/roof-molding checks by VIN.
Buyer: Treat 2022 as a launch-year NX4 unless the market says otherwise. Check roof molding, tow-hitch wiring and hybrid coolant levels before comparing trims.
Owner: Keep the first dealer service records complete; launch-year nuisance repairs look worse if undocumented.
2023
NX4 range matures, but electric oil-pump controller recall 246 / 23V526 affects certain vehicles.
Buyer: This is a good buying year only after recall 246 is closed. If stop-start or transmission warnings appear, do not assume software until the pump controller is checked.
Owner: Finish EOP recall work promptly and watch for hot-electronics smell or transmission warnings after long drives.
2024
Recall exposure continues: electric oil pump on some cars, MDPS recall 261 / 24V412 on a small population, and tow-hitch harness recall on equipped vehicles.
Buyer: A 2024 Tucson needs a full VIN printout. Steering assist, tow harness and EOP status are worth more than wheel size or trim badges.
Owner: If you have a hitch harness, inspect it after rain and complete recall work; do not wait for trailer-light faults.
2025
Facelift/refresh in some markets with new recall checks, including connecting-rod-bolt recall 281 / 25V549 on affected Tucson/Santa Fe production.
Buyer: Buy only after VIN clears engine recall 281 or shows completed remedy. A nearly new 2025 with knock or oil leak is a dealer problem, not a bargain.
Owner: Keep engine-recall documentation and report any knock, oil leak or power-loss warning immediately while warranty leverage is strongest.
Common problems
Faults to check before buying
What fails, what it looks like, what it costs, and the quick checks you can do at the viewing - ranked by how badly each one can hurt you.
Fault 1
2021 HECU / ABS module fire recall
Affects
2021 TL-generation Tucson under Hyundai recall 195 / NHTSA 20V543.
Symptoms
Often no warning; possible ABS/ESC lights, burning smell, smoke or heat marks near the hydraulic electronic control unit.
Typical repair cost
EUR 0 under recall; EUR 900-1,800 retail HECU/module repair if unsupported.
Codes / scan clues
ABS/ESC module codes if already failing; absence of codes does not clear the fire recall.
Root cause: The HECU can corrode internally and short, creating engine-compartment fire risk.
Quick check
- Confirm the 2021 is old TL generation or market-specific NX4.
- Run VIN for Hyundai recall 195 / NHTSA 20V543.
- Inspect ABS module area for corrosion, heat marks or non-factory wiring.
- Confirm fuse/software/remedy paperwork.
- Do not buy an unrepaired affected car to park inside.
Buyer note
This is the 2021-specific hard gate. A clean recall printout turns it into a normal older Tucson; an open fire recall does not.
Owner note
If open, follow park-outside guidance until complete and keep the dealer invoice for resale.
Fault 2
Transmission electric oil pump controller overheating
Affects
Certain 2023-2024 Tucson under Hyundai recall 246 / NHTSA 23V526.
Symptoms
Burning smell, smoke, warning messages, poor transmission operation, stop-start issues or parked fire concern.
Typical repair cost
EUR 0 under recall; EUR 500-1,200 retail pump/controller repair.
Codes / scan clues
Transmission/ISG-related codes vary; Hyundai scan required.
Root cause: Damaged electrical components in the Idle Stop & Go electric oil pump controller can overheat.
Quick check
- Run VIN for recall 246 / 23V526.
- Ask for electric oil pump controller inspection/replacement record.
- Smell engine bay after the drive.
- Check stop-start and transmission warnings only after recall status is known.
- Reject any smoke story.
Buyer note
A new-looking Tucson with an open EOP recall is not clean stock. Close the campaign before buying.
Owner note
Do not postpone this one; the recall exists because the controller can overheat.
Fault 3
Tow hitch harness water ingress and fire risk
Affects
2022-2024 Tucson with optional Mobis tow hitch wiring harness under Hyundai recall 290 / NHTSA 25V893.
Symptoms
Trailer lights fail, blown fuses, burning smell, battery drain, corrosion at trailer module or recall notice advising outside parking.
Typical repair cost
EUR 0 under recall; EUR 200-700 retail harness/module repair if unsupported.
Codes / scan clues
Body/trailer lighting codes possible; often no powertrain DTC.
Root cause: Incorrect harness location/installation can allow water into the tow-hitch control module, shorting the module and creating fire risk.
Quick check
- Confirm whether hitch wiring is fitted even if the ball mount is absent.
- Run VIN for 25V893 / Hyundai 290.
- Inspect module and harness for corrosion or water tracks.
- Test trailer-light output if possible.
- Avoid unrepaired cars until the remedy is completed.
Buyer note
This is not just a towing accessory fault. If the harness is fitted and recall is open, price and storage risk change.
Owner note
Park outside if Hyundai/NHTSA advice applies and get the harness replaced when parts are available.
Fault 4
2025 connecting rod bolt engine recall
Affects
Certain 2025-2026 Tucson and Santa Fe under Hyundai recall 281 / NHTSA 25V549.
Symptoms
Engine knock, oil leak, loss of drive power, warning light, or VIN recall notice before any symptom appears.
Typical repair cost
EUR 0 under recall; EUR 5,000-10,000+ engine replacement if unsupported.
Codes / scan clues
Misfire, knock or oil-pressure codes after damage; recall status is the key.
Root cause: Connecting rod bolts may have been improperly tightened during assembly, risking engine damage and power loss.
Quick check
- Run VIN for recall 281 / 25V549.
- Ask whether inspection or engine replacement was required.
- Cold-start and listen for deep knock.
- Inspect for lower-engine oil leaks.
- Do not buy symptomatic 2025 stock before dealer resolution.
Buyer note
Nearly new does not mean low-risk here. A 2025 Tucson with open engine recall belongs at Hyundai, not in your driveway.
Owner note
Report knock, oil leak or power loss immediately while the campaign and warranty trail are fresh.
Fault 5
2024 MDPS electric power steering short
Affects
Certain 2024 Tucson and Santa Cruz under Hyundai recall 261 / NHTSA 24V412.
Symptoms
Heavy steering, EPS warning, intermittent assist loss or steering effort changing suddenly.
Typical repair cost
EUR 0 under recall; EUR 900-2,000 retail MDPS electric power pack replacement.
Codes / scan clues
C-series MDPS/EPS codes; scan steering module directly.
Root cause: Circuit board in the motor-driven power steering assembly may short circuit, causing loss of power assist.
Quick check
- Run VIN for 24V412.
- Confirm MDPS electric power pack replacement where affected.
- Turn lock-to-lock at parking speed.
- Scan EPS/MDPS module.
- Reject active steering warning.
Buyer note
Small recall population, big consequence. Steering assist faults are not a wait-and-see item.
Owner note
Keep the MDPS recall paperwork; later steering symptoms need a known baseline.
Fault 6
Hybrid/PHEV coolant loss and cooling-circuit leaks
Affects
2022-2025 Tucson Hybrid/PHEV 1.6 T-GDi; owner-reported more than recall-proven.
Symptoms
Sweet coolant smell, low engine or inverter reservoir, residue at hose joints, heat-management warning, hybrid warning or dealer pressure-test history.
Typical repair cost
EUR 150-500 hose/clamp/diagnosis; EUR 700-1,800 pump/heat-exchanger/radiator work.
Codes / scan clues
P0A/P1 hybrid cooling codes may appear; monitor temperature data.
Root cause: Evidence points to individual hose, clamp, reservoir or heat-exchanger faults rather than one universal defect. Low coolant still matters because hybrid thermal control is central to reliability.
Quick check
- Check both coolant reservoirs cold.
- Smell engine bay after the drive.
- Look for coloured residue at hose joints and heat exchangers.
- Ask for pressure-test paperwork if coolant was topped up.
- Reject hybrid warnings with low coolant.
Buyer note
Low coolant on a hybrid is not a small top-up. It needs a pressure-test explanation before purchase.
Owner note
Photograph reservoir levels monthly if the car has had a coolant complaint; trends help dealers fix intermittent leaks.
Fault 7
Hybrid 6-speed launch lag, vibration or transmission warnings
Affects
2022-2025 Tucson Hybrid/PHEV with 1.6T hybrid and 6-speed automatic.
Symptoms
Delay pulling away, flare before engagement, vibration under light load, harsh 2-3 shift, check hybrid system or drivetrain warnings.
Typical repair cost
EUR 150-350 software/adaptation diagnosis; EUR 1,200-3,000 actuator/clutch/valve-body work; EUR 4,000-7,000 transmission replacement.
Codes / scan clues
Hybrid and transmission control-module codes; exact DTCs require Hyundai scan.
Root cause: Owner evidence points to hybrid clutch/transaxle control, calibration, communication or hardware faults. It is not yet one clean recall defect, so the road test and scan matter.
Quick check
- Test cold pull-away in normal and sport/HEV modes.
- Pull away gently uphill.
- Watch for revs rising without acceleration.
- Scan hybrid and transmission modules.
- Avoid repeat dealer visits with no diagnosis.
Buyer note
If a hybrid Tucson hesitates or flares during the viewing, do not assume it is normal hybrid behaviour.
Owner note
Ask the dealer to document module codes and adaptations; intermittent hybrid faults need a paper trail.
Fault 8
EU 7DCT clutch judder and adaptation problems
Affects
Non-US 1.6 T-GDi or diesel Tucson variants with 7-speed DCT.
Symptoms
Jerky low-speed take-up, clutch smell, reverse hesitation, shudder in traffic or harsh shifts after adaptation.
Typical repair cost
EUR 150-350 adaptation/software; EUR 900-1,800 clutch pack; EUR 2,000-4,000 mechatronic/gearbox work.
Codes / scan clues
DCT clutch/adaptation codes vary by scan tool.
Root cause: Dry dual-clutch transmissions are sensitive to heat, low-speed manoeuvring and adaptation. This is market-specific and should not be applied to US 2.5/8AT cars.
Quick check
- Verify gearbox type by VIN.
- Crawl in traffic until warm.
- Reverse uphill slowly.
- Smell for clutch after manoeuvres.
- Reject violent shudder described as normal DCT.
Buyer note
The DCT can be fine, but it must be tested hot. A five-minute suburban drive will miss the fault.
Owner note
Avoid holding the car on throttle on hills; use the brake and let the clutch cool in traffic.
Fault 9
Roof molding detachment
Affects
Certain 2022 Tucson and related 2022-2023 Santa Cruz vehicles under recall 241 / NHTSA 23V038.
Symptoms
Loose roof side molding, wind noise, trim lifting after motorway use or missing roof trim.
Typical repair cost
EUR 0 under recall; EUR 150-500 retail trim repair.
Codes / scan clues
None.
Root cause: Roof moldings may loosen and detach, creating road-hazard risk.
Quick check
- Run VIN for 23V038.
- Gently check roof moldings for looseness.
- Look for glue or clip repairs.
- Listen for wind noise at speed.
Buyer note
Low-cost compared with the fire recalls, but it is easy to inspect and should be closed before sale.
Owner note
If the molding lifts, repair it before it leaves the car and becomes someone else's hazard.
