Creaking or crunching noise from the front end when negotiating speed bumps or uneven surfaces, particularly noticeable in cold weather. This is caused by dry or worn front lower control arm bushes and anti-roll bar bushes.

Typically appears

40,000-60,000 miles

What to inspect

Push down firmly on the front wings to bounce the suspension, or drive over a forecourt speed bump at low speed with the windows down, listening carefully for a dry rubber creak.

Loss of cabin heat on one or both sides. This occurs when the silica bag inside the coolant expansion tank splits, releasing silicates that circulate and permanently block the internal channels of the heater matrix.

Typically appears

50,000-80,000 miles

What to inspect

Run the engine up to operating temperature, set the climate control to maximum heat, and verify that hot air blows consistently from all dashboard vents. Check the coolant tank for discoloured, sludgy fluid.

Damp carpets in the front footwells or water dripping from the headliner near the sun visors. This is caused by blocked, kinked, or detached drain tubes on models fitted with the panoramic sunroof.

Typically appears

3-5 years

What to inspect

Press your hand firmly into the front carpets and feel the headliner around the A-pillars for dampness. Open the sunroof fully and inspect the front corner drain holes for visible debris or standing water.

Electric tailgate groans, fails to open fully, or drops back down after opening. The motorised spindle drive struts lose internal pressure or suffer motor failure, requiring complete replacement of the strut units.

Typically appears

4-6 years

What to inspect

Operate the electric tailgate using both the key fob and the boot button. Ensure it opens smoothly without grinding noises, reaches its maximum height, and holds its position without sagging.
