What to look out for
Serious issue
With the engine off, pump the brake pedal five times to exhaust residual vacuum, then hold firm pressure on the pedal and start the engine.
Brake Vacuum Servo (Booster) Diaphragm Failure
The brake vacuum servo (booster) fitted across all three Impreza generations uses a rubber diaphragm to multiply pedal force using manifold vacuum. On EJ15 and EJ20 engines the manifold vacuum can be lower than specification due to age-related inlet manifold gasket leaks and idle control valve degradation, which reduces servo effectiveness. On higher-mileage examples the servo diaphragm itself cracks or stiffens, causing a total or partial loss of brake assistance. This results in a dramatically increased pedal effort required to achieve the same braking force, which can be dangerous in emergency situations. A failed servo can also allow a vacuum hiss from the servo housing.

Costly issue
Run a finger inside each rear wheel arch lip feeling for bubbles.
Rust in JDM imports — rear arches, sills and underbody
Most NZ Imprezas of this era are ex-Japan imports, and cars from snowy prefectures spent winters on salted roads. Rust shows in the rear wheel arch lips, sill seams, around the fuel filler, boot floor seams and on suspension components underneath. Surface rust on subframes is common and manageable; bubbling arch lips and crusty sill seams mean expensive panel work and can become WoF issues. Border checks catch the worst, but plenty of borderline cars are on NZ roads.
What you would notice
Costly issue
With engine running, turn the steering wheel slowly from lock to lock and listen for a knock or rattle that changes with steering angle.
Electric Power Steering Rack Rattle and Knock
The GE-series Impreza replaced hydraulic power steering with a column-mounted electric power steering (EPS) unit, and the steering rack itself uses a rack-and-pinion design with a spring-loaded yoke that holds the rack against the pinion gear. Over time the yoke adjuster preload diminishes due to wear of the plastic yoke pad, allowing the rack to develop measurable radial play. This produces a knock or rattle over road imperfections that is transmitted directly through the steering column to the wheel. Additionally, the EPS control module can develop software or sensor faults that cause intermittent loss of power assist or a steering wheel that requires excess effort on one lock, logged as fault code C0057 or C1511.
What you would notice
Costly issue
Excessive movement at the inner pivot point indicates bush failure.
Front lower arm inner bush failure causing vibration
The front lower control arm inner pivot bushes on the GH/GE Impreza degrade from around 80,000 km onward, with NZ/AU road conditions accelerating wear. The inner bush is a hydraulic or rubber-bonded unit pressed into the front subframe. When it fails or collapses, the lower arm pivot point moves under braking and cornering loads, producing steering vibration through the wheel under braking, wandering straight-line tracking, and a clunking or knocking sound over sharp bumps. The failure also causes inner-edge tyre wear if camber shifts as the deflected bush alters suspension geometry under load.
What you would notice
Costly issue
Look for fresh oil staining or dried oil residue on the driveshaft CV boots or differential housing.
Rear differential output shaft oil seal leak
GH/GR Impreza AWD models commonly develop oil leaks at the rear differential output shaft seals. The seals deteriorate with age and heat cycling, allowing differential oil to weep onto the driveshafts and rear subframe. Left unattended, oil loss from the rear diff leads to differential wear and eventual bearing failure. This is a documented pattern on AWD Subaru platforms of this era and is often found during pre-purchase inspections.
What you would notice
Costly issue
Spin the hub by hand and listen for grinding or roughness.
Rear wheel bearing failure
GD/GG and GH/GR Impreza rear wheel bearings have a documented shorter-than-expected service life, particularly on all-wheel-drive variants where the rear axle carries more load and is subject to greater lateral stress in corners. Bearings commonly fail in the 100,000–160,000 km range. NZ/AU roads and gravel exposure accelerate wear. Failure can progress from a hum to a roar, and in advanced cases can allow wheel play which affects brake and suspension geometry.

03Front Lower Control Arm Ball Joint Wear
The front lower control arm ball joints on both GD and GE Impreza models are a serviceable pressed-fit design, but the ball joint housing is vulnerable to accelerated wear when driven over the unsealed roads common in New Zealand. Grit and water ingress past the rubber boot causes the steel ball and socket to wear unevenly, increasing radial and axial play beyond the manufacturer's specification of approximately 0.5 mm. Once wear exceeds this limit the wheel can track inconsistently under braking and cornering, and in severe cases the joint can separate without warning, causing total loss of steering and wheel control. Both the GD MacPherson strut and GE multi-link front geometry rely on the lower ball joint as the primary lateral locating point.
Example of the part — not this vehicleA separated lower ball joint: the control arm has dropped and the wheel has splayed out under the guard.

09Electric Power Steering Column Coupling Creak and Knock
The GE/GH Impreza generation introduced electric power steering (EPS) in place of the hydraulic system used on the GD. The intermediate steering shaft coupling between the EPS motor column and the steering rack pinion develops a creak, knock, or clunk, particularly at low speed and when the steering is loaded during parking manoeuvres or at walking pace. Subaru issued a TSB addressing the issue through lubrication of the intermediate shaft splines and universal joint with a specified molybdenum disulphide grease. In some cases the EPS motor itself develops a groan under maximum steering lock.

01WRX/STI piston ringland failure (tuned/thrashed turbo cars)
Can't confirm for this car
Can't confirm for this car
Turbo Impreza variants (GD/GG and GH/GR WRX and STI, heavily represented among NZ JDM imports) crack piston ringlands, especially the EJ255 and any car that has been tuned, run lean, or fed 91 octane. A cracked ringland shows up as compression loss and oil consumption in one cylinder and means an engine rebuild. NZ has a huge population of ex-Japan WRXs with unknown tuning history, which makes a compression/leak-down test essentially mandatory on any turbo Impreza.

Non-turbo 2.5 Imprezas (GD 2.5i/RS and GH/GE 2.5i) share the EJ251/EJ253 external head gasket leak that plagues same-era Foresters and Legacys — a slow oil/coolant weep at the head-to-block joint from around 150,000 km that eventually causes coolant loss and overheating. JDM 1.5/2.0 EJ15/EJ20 cars (the bulk of NZ imports) are much less affected, so this mainly matters on NZ-new and US-spec 2.5 cars. Repair is both sides with MLS gaskets plus timing belt/water pump while apart.

Can't confirm for this car
The EJ154 1.5-litre engine introduced on the GH-generation Impreza (base model, not WRX) uses a timing chain that has documented premature stretch and chain guide wear, particularly after 80,000–120,000 km. Unlike the larger EJ20, the EJ154 has less robust guide material. Chain stretch causes timing retard, rough idle, and increased fuel consumption. In severe cases the chain can skip a tooth or break, causing valve-to-piston contact. This was a new failure mode not seen on the earlier EJ15.
Example of the part — not this vehicleThe front of a twin-cam engine with the timing cover off — chain, sprockets and guides.

11DCCD Centre Differential Actuator Failure (GD WRX STI)
Does not apply
Does not apply
GD-generation Impreza WRX STI models fitted with the Driver's Control Centre Differential (DCCD) use an electro-hydraulic actuator to vary the torque split ratio of the centre differential between 35:65 and 50:50 front-to-rear on demand. The actuator solenoid and position sensor assembly is susceptible to moisture ingress from the tunnel area and develops internal corrosion that either causes the actuator to stick at a fixed position or fail open, locking the DCCD into a set torque split regardless of driver input or the automatic mode logic. A stuck-closed actuator causes heavy understeer and binding during tight-radius turning, with associated driveline clunking.

Does not apply
Does not apply
The FB20D engine fitted to the GK/GT Impreza uses rubber valve stem seals that harden and lose elasticity as mileage accumulates, typically becoming problematic after 80,000-120,000 km. Degraded seals allow engine oil to drain past the intake and exhaust valve guides during overnight cold soaks, pooling in the combustion chamber and producing a puff of blue-grey smoke on initial cold startup. Oil consumption accelerates as the condition progresses, and the smoke disappears after the first minute of running, which can allow the issue to be missed during a brief inspection.

01e-Boxer High-Voltage Lithium-Ion Battery Degradation
Does not apply
Does not apply
The e-Boxer mild hybrid system fitted to select Impreza models uses a lithium-ion traction battery (approximately 118 V) housed beneath the rear seat/boot floor to power an electric motor integrated between the engine and CVT. As with all lithium-ion chemistry, the battery undergoes capacity degradation over time and charge cycles, reducing the electric assist contribution and fuel economy. In more advanced degradation, the battery management system may disable the hybrid assist entirely and store fault codes, and partial cell failure can trigger hybrid system warning lights that require dealer diagnosis with Subaru Select Monitor.

Does not apply
The EyeSight dual-camera system mounted behind the upper windshield on GK/GT Impreza is susceptible to internal condensation and fogging between the camera housing and windshield glass, triggered by temperature cycling, age of the windshield interlayer, or minor stone chip contamination near the camera bracket zone. Once fogged, the EyeSight system disables itself as it cannot achieve stereo image lock. Critically, any windshield replacement on an EyeSight-equipped model mandates an OEM-spec glass and a dealer-performed stereo camera recalibration, making even a minor chip repair economically significant.

01Front lower control arm bush collapse
Does not apply
Does not apply
The GK/GT Impreza (2016 onward) global platform uses front lower control arms with pressed rubber bushes that have shown premature degradation in Australasian conditions. Bush failure causes increased toe variation under braking and cornering, which produces understeer, steering wander, and increased tyre wear. This is documented across the GK global platform including XV and Forester variants on the same architecture. Bush collapse is accelerated on cars driven on unsealed or corrugated roads.

02Front Strut Knuckle and Hub Carrier Rust-Through
Does not apply
Does not apply
The GD Impreza front strut hub carriers (knuckles) are cast iron and in New Zealand's coastal and high-rainfall regions develop severe surface corrosion that penetrates into the wheel bearing bore and brake caliper mounting faces. Severe rust swells the bore, causing the wheel bearing outer race to spin in the housing (spun bearing), which cannot be corrected by a bearing replacement alone — the knuckle itself must be replaced. The brake caliper slide bolt threads also corrode into the knuckle bosses, requiring heat and extraction, and seized ABS reluctor ring mounting faces complicate brake disc replacement.

GP/GJ Impreza front wheel bearings have a documented pattern of premature failure, typically appearing in the 80,000–140,000 km range. The front bearing design on this platform is not as robust as earlier generations. AWD torque loads through the front hubs under hard cornering and acceleration accelerate wear. Failure often presents as a directional hum that changes character when cornering. Left too long, a failed front bearing affects steering, braking stability, and ABS sensor function.

The TR580 Lineartronic CVT on GK/GT Impreza models has documented fluid seepage from the external cooler lines (rubber-to-metal crimp joints) and the CVT filter housing o-ring on higher-mileage or aged units. CVT fluid is a thin, reddish oil and the seeps are often subtle but visible as pink-red staining on the underside of the transmission tunnel and subframe. Loss of CVT fluid is serious as the TR580 is highly sensitive to fluid level; even slight underfilling accelerates belt and pulley wear and can lead to catastrophic unit failure.

02Rear Differential Pinion and Side Seal Oil Leaks
Does not apply
Does not apply
The rear differential fitted to GD AWD Imprezas develops oil leaks from the pinion input shaft seal and both rear axle side seals. The pinion seal is a lip-type rubber seal that hardens with heat cycling and begins to weep gear oil past the propeller shaft flange. Side seals deteriorate similarly, allowing gear oil to migrate down the inside of the rear axle shafts and contaminate the rear brake drums or disc assemblies. Neglected leaks cause the rear differential to run low on oil, leading to hypoid gear and bearing damage. NZ conditions with gravel road dust and moisture accelerate lip seal deterioration.

Subaru Impreza buyer questions
Is the Subaru Impreza reliable?
Like any used car, it depends on the specific example and its service history. Across the 44 documented faults for the Subaru Impreza, the recurring problem areas are engine, cooling, and brakes. A Subaru Impreza with a full service history and no signs of the issues listed on this page can be a sound buy but each one needs to be checked individually before you commit.
What are the most common problems with a used Subaru Impreza?
We've catalogued 44 known faults for the Subaru Impreza, covering engine, cooling, and brakes. All 44 are written out in full on this page, with the symptoms to notice, what to inspect, and typical repair costs for each. Free to read, no account needed.
How much do repairs cost on a Subaru Impreza?
Most single repairs on the Subaru Impreza fall between $450–$2,000 at NZ independent-workshop rates. Some of the 44 documented faults cost less and a few cost considerably more, and no one car needs them all. Knowing which ones to look for before you view is what lets you negotiate the price down or walk away.
Should I get a pre-purchase inspection on a Subaru Impreza?
Yes. A Subaru Impreza inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $24.90 far less than the cost of missing one of the faults on this page.
