Build the inspection planSafetyHigh
ABS module fire recall.
- Typically appears
- Any
- What to inspect
- Confirm the ABS/HECU recall was completed.
ElectricalLow
Infotainment and camera glitches.
- Typically appears
- Age-related
- What to inspect
- Test the screen and reversing camera.
Exhaust/EmissionsHigh
DPF warning light illumination and vehicle entering limp-home mode due to soot accumulation, particularly on 1.7 and 2.0 CRDi models used for short journeys.
- Typically appears
- 40,000-70,000 miles
- What to inspect
- Start the engine and check the instrument cluster for the DPF warning light. Rev the engine to 3,000 rpm to ensure it revs freely and has not defaulted to limp mode.
Body/InteriorMedium
Creaking, rattling, or sticking of the panoramic sunroof mechanism, caused by track debris or failing plastic guides.
- Typically appears
- 30,000-60,000 miles
- What to inspect
- Operate the sunroof through a full open and close cycle. Listen for grinding noises and check that the glass seats flush with the roofline without manual assistance.
Climate ControlMedium
Air conditioning system blowing warm air due to a porous or stone-damaged condenser leaking refrigerant.
- Typically appears
- 50,000-80,000 miles
- What to inspect
- Set the climate control to maximum cold with the engine running. Feel the vents for chilled air within 60 seconds and shine a torch through the lower front bumper grille to spot dark, oily patches on the condenser.
SteeringMedium
Noticeable clicking or clunking noise from the steering column when turning the wheel, caused by a degraded flexible rubber coupling within the EPS motor assembly.
- Typically appears
- 60,000-90,000 miles
- What to inspect
- With the engine idling and wheels pointing straight, rapidly rock the steering wheel left and right by about 10 degrees. Listen for a distinct metallic clunk from behind the dashboard.

Build my inspection planFrequently asked questions
Is the Tucson reliable?
Value-packed but check the dual-clutch and engine history carefully.
Are there Tucson engine recalls?
Yes — GDI engine and ABS-fire campaigns exist; confirm completion.
Should I avoid the 1.6T DCT?
Test it thoroughly; the dual-clutch can be jerky and troublesome.
Do the 1.7 and 2.0 CRDi diesel engines use a timing belt or a timing chain?
Both the 1.7-litre and 2.0-litre CRDi diesel engines fitted to the Mk3 Tucson utilise a steel timing chain rather than a rubber cambelt. These chains are designed to last the lifetime of the vehicle, provided the car receives regular oil changes using the correct specification synthetic oil to prevent tensioner failure.
What should I check on the HTRAC all-wheel-drive system?
The HTRAC AWD system is generally robust, but the transfer case and rear differential require fluid changes every 40,000 miles to prevent premature wear. When inspecting, check the rear differential casing for oil leaks and ensure there is no binding or juddering from the drivetrain during tight, low-speed manoeuvres.
Are there any specific checks required for the 48V mild-hybrid models?
Introduced during the 2018 facelift, the 48V mild-hybrid system features a lithium-ion battery located under the boot floor. Dealers must ensure the boot area is completely dry, as water ingress from faulty tailgate seals can damage the battery and DC/DC converter. Replacement of these high-voltage components is highly expensive.
