Most Common Subaru Impreza Mk3 (GE/GH/GR) Faults & Repair Costs

Moderate Risk

Steering Rack Leaks

Est. Cost£450–£900

Hydraulic steering racks on Mk3 Imprezas can leak from the seals, eventually causing heavy steering and pump noise.

Warning Signs:

Heavy steering, Whining pump, Fluid around the rack gaiters

Moderate Risk

Rear Arch and Underbody Corrosion

Est. Cost£300–£2,000

Rust commonly starts around the rear arches, sill ends and suspension mounting areas, especially on cars that have lived through many salty UK winters.

Warning Signs:

Bubbling paint on rear arches, Flaky underseal, Corrosion advisories near suspension mounts

High Risk

Boxer Diesel Crankshaft Failure

Est. Cost£3,000–£6,000

Diesel Mk3 Imprezas inherit the same EE20 bottom-end risk seen elsewhere in the Subaru range, making them one of the least forgiving versions to buy blind.

Warning Signs:

Engine knock, Low oil pressure, Sudden engine failure

Essential Pre-Purchase Step

Buying a used Subaru Impreza Mk3 (GE/GH/GR)? 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 Mk3 (GE/GH/GR) Buyers

Inspect rear arches, sills and the rear subframe area carefully; corrosion can be much worse underneath than it appears in photos.
Check the steering rack gaiters and fluid level before driving, then listen for pump whine on full lock.
Treat diesel examples as specialist purchases only and avoid cars with thin history.
