Most Common Subaru Impreza Mk2 (GD/GG) Faults & Repair Costs

High Risk

Rear Strut Tower, Sill and Arch Corrosion

Est. Cost£500–£3,000

Mk2 shells can rot badly around the rear strut tops, sills and rear arches, sometimes hiding serious structural decay behind trim and underseal.

Warning Signs:

Rust bubbles around rear arches, Damp or rust inside the boot side trim, Corrosion advisories near suspension mounts

What to Check Before Buying:
  • Lift the boot trim around both rear strut towers
  • Inspect the sill ends and rear arch lips
  • Check underneath for previous welded repairs

Moderate Risk

Radiator End Tank Cracking

Est. Cost£200–£450

Ageing factory radiators can split around the plastic end tanks, causing coolant loss that is easy to miss until the car gets hot in traffic.

Warning Signs:

Sweet coolant smell, Low coolant level, Staining around radiator seams

What to Check Before Buying:
  • Inspect the top corners of the radiator
  • Check for dried coolant marks after the drive
  • Confirm the cooling fans cycle normally

Moderate Risk

Wheel Bearing Wear

Est. Cost£180–£400 per corner

Rear wheel bearings in particular can get noisy as the cars age, bringing a droning noise that is often mistaken for tyre roar.

Warning Signs:

Humming or droning that rises with speed, Rumble from one rear corner, Noise changes on sweeping bends

What to Check Before Buying:
  • Drive at A-road speed and listen for a steady drone
  • Check for play or roughness at each wheel if inspected on a lift

Essential Pre-Purchase Step

Buying a used Subaru Impreza Mk2 (GD/GG)? Always check for hidden finance and write-off history.

Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.

Inspection Checklist for Subaru Impreza Mk2 (GD/GG) Buyers

✓Lift the boot trim and inspect the rear strut towers carefully; corrosion here can be much worse than the bodywork suggests.
✓Check the radiator for staining or cracks around the plastic end tanks before and after the test drive.
✓Listen for wheel-bearing drone on a faster road, especially from the rear axle.
