Problem 1
Hyundai Tucson: Blocked DPF or sooted EGR valve on the CRDi diesel
What goes wrong
Short urban trips stop the particulate filter from regenerating, and soot builds up in the EGR valve.
How to check it yourself
Read codes and live data: DPF soot load and pressure, EGR valve position.
The usual fix
Regenerate with a motorway drive or a forced regeneration; clean or replace the EGR valve; clean or replace a DPF that stays blocked.
Signs: Loss of power, Check engine light
Fault codes: P2002, P2463, P0401, P0402
Problem 2
Hyundai Tucson: DCT gearbox judder or hesitation at low speed
What goes wrong
The dry dual clutches judder when pulling away in slow traffic, especially when cold; early software made it worse.
How to check it yourself
Note whether it happens mainly when moving off in traffic. Read the gearbox codes and ask a dealer about software updates.
The usual fix
Dealer software update and clutch re-learn; worn clutches are replaced (check the manufacturer’s warranty first).
Signs: Harsh shifting, Transmission slipping
Problem 3
Hyundai Tucson: Clunk over bumps from worn drop links or bushes
What goes wrong
The anti-roll bar drop links and control-arm bushes wear, giving a knock over speed bumps and a creak at low speed.
How to check it yourself
With the car on the ground, have someone rock it side to side while you listen and feel at each drop link. Lift the front and check the drop-link ball joints and arm bushes for play.
The usual fix
Replace the worn drop links (usually in pairs) or control-arm bushes.
Signs: Clunk over bumps, Noise when turning
