The 2.5L EJ253 naturally-aspirated engine in 1999-2011 Imprezas is notorious for external head gasket failure. The composite head gaskets degrade over time, allowing coolant and oil to seep externally at the gasket mating surfaces. Unlike a typical blown head gasket that causes coolant-oil mixing, Subaru EJ25 head gaskets typically leak externally first. The boxer engine design means gaskets are at the bottom of the heads, making leaks drip downward and often go unnoticed. If left unaddressed, external leaks can progress to internal coolant-oil mixing and overheating.

Common Symptoms

  • Oil seepage visible on bottom of engine near head gasket area
  • Coolant level slowly dropping without visible external puddles
  • Sweet coolant smell from engine bay
  • Oil spots on garage floor near front of vehicle
  • Overheating in severe cases (internal gasket breach)
  • Bubbles in coolant overflow reservoir

How to Fix

Replace both head gaskets with updated MLS (multi-layer steel) gaskets (Subaru OEM 11044AA770 or Six Star MLS set). Resurface both cylinder heads to within 0.002 inch flatness spec. Replace timing belt, water pump (21111AA370), thermostat, and all seals while the engine is apart. Add Subaru Cooling System Conditioner (SOA635071) after repair. Budget 8-12 hours labor for the complete job.

The 2.5L DOHC EJ25D and the 1997-and-later SOHC EJ engines are interference designs: if the rubber timing belt breaks or a belt idler/tensioner pulley seizes, the pistons strike open valves and bend them, destroying the top end. From 1997 all USDM Subaru EJ engines (including the 2.2L SOHC) became interference after a piston/head redesign. Subaru specifies belt replacement at roughly 105,000 miles/105 months, but the belt gives no warning before it snaps, and on 25-30 year-old cars idler pulleys and tensioners are as likely to fail as the belt. Many high-mileage 1990s Imprezas are running on overdue belts, making this a leading cause of catastrophic engine loss on otherwise-sound cars. (Note: the earlier EJ18 and pre-1997 EJ22 SOHC are non-interference, so belt failure there is far less destructive.)

Common Symptoms

  • No specific warning symptom before failure
  • Sudden no-start / no compression after belt break
  • Rattling or whining from a failing idler/tensioner pulley
  • Bent valves and severe engine damage after failure

How to Fix

Replace the timing belt on the ~105k-mile/roughly-decade interval and always replace the belt idler pulleys, tensioner, and water pump at the same time (the pump is belt-driven and buried behind the covers). Inspect cam/crank seals and replace if weeping. Do not defer on an interference EJ25 or 1997+ engine.

The first-generation 2.5L DOHC boxer (EJ25D) used in the 1998-1999 Impreza 2.5 RS (and shared with the 1996-1999 Legacy/Outback/Forester of the era) is notorious for internal head gasket failure. In 1996 Subaru used a composite gasket, then from 1997 switched to a multi-layer-steel shim gasket with a graphite outer film; the film between the combustion chamber and the cooling jacket degrades (typically around 100,000 miles), allowing coolant into the combustion chamber and combustion gases into the cooling jacket. Because the flat-four has two heads and the failure is typically internal (coolant-to-combustion) rather than the external weep seen on the later 2.5 SOHC, the classic pattern is overheating on the highway that cools off in town, and it can warp a head if driven on. This is the defining reliability problem of the DOHC-era 1990s Impreza.

Common Symptoms

  • Overheating, especially on long freeway drives or climbing grades
  • Oily film or coolant loss in the overflow/expansion bottle
  • Exhaust, fuel, or sulfur smell in the coolant reservoir
  • Intermittent high coolant-temperature gauge readings
  • Coolant loss with no obvious external leak
  • White exhaust smoke / bubbling in the coolant

How to Fix

Replace both head gaskets with updated multi-layer-steel gaskets, resurface/pressure-test the heads, and replace the timing belt, water pump, and thermostat while the front of the engine is open. Many owners upgrade to the revised OEM gasket or a quality MLS gasket set. A cooling-system flush and new coolant conditioner is standard on reassembly.

2008-2016 Imprezas (and related Crosstreks) have a known issue with rear coil springs fracturing, particularly in cold climates and areas that use road salt. The broken spring can puncture a tire, damage brake lines, or cause a sudden change in ride height and handling. Subaru issued a recall (WQH-74/NHTSA 19V-236) for 2008-2014 models covering free spring replacement. Later models (2015-2016) also experience the issue but may not be covered by recall.

Common Symptoms

  • Clunking noise from rear suspension
  • Vehicle sitting lower on one side
  • Visible crack or break in rear coil spring
  • Tire damage from broken spring end
  • Rattling noise over bumps from rear

How to Fix

Inspect rear coil springs for cracks or breaks, especially at the bottom coil. For 2008-2014 models, this is covered under Subaru recall WQH-74 (NHTSA 19V-236) - dealer will replace both rear springs and add protective spring covers at no cost. For non-recall models, replace with updated springs that include the protective coating. Spring part numbers: 20380FJ010 (left), 20380FJ020 (right) for 2012+ Impreza.

The rear trailing arm bushings on Imprezas corrode and fail, particularly in salt-belt states. The steel sleeve inside the rubber bushing rusts and expands, tearing the rubber apart. This causes clunking noises, vague rear-end handling, and uneven rear tire wear. In severe cases, the bushing can separate completely, allowing the rear wheel to shift its alignment dramatically. Subaru issued a recall (WRF-99) on some models for trailing arm corrosion.

Common Symptoms

  • Clunking from rear over bumps
  • Rear end wanders or feels loose in corners
  • Uneven rear tire wear (inner or outer edge)
  • Visible rust and cracking around rear trailing arm bushings
  • Rear wheels appear to toe-out when viewed from behind

How to Fix

Replace rear trailing arm bushings. Inspect the trailing arm itself for corrosion — if the arm is heavily corroded, replace the entire trailing arm assembly. Whiteline or Kartboy polyurethane bushings resist corrosion better than OEM rubber-and-steel construction. Apply anti-seize to all bolts during reinstallation. Get a 4-wheel alignment after replacement.

Pressed-in front wheel bearings on the 1993-2001 Impreza chassis are a recurring wear item; the bearings were sized for the small factory 15-16 inch wheels, and larger aftermarket wheels, high mileage, or hard cornering accelerate failure. A failed bearing hums or roars proportional to road speed, often changing pitch under cornering load as weight shifts across the bearing. Because the bearing is pressed into the knuckle, DIY replacement effectively requires a hydraulic press, so most owners pay a shop or replace the whole knuckle/hub assembly.

Common Symptoms

  • Humming or roaring that rises with vehicle speed
  • Noise pitch changes when cornering left vs. right
  • Play/wobble at the wheel when rocked on a jack
  • Growling that worsens over time

How to Fix

Press in a new wheel bearing (and new seals plus axle nut), or replace the hub/knuckle assembly. Doing bearings in axle pairs is common. Owners with larger wheels sometimes convert to the later bolt-on hub design. If a bearing has been noisy a long time, replace the hub too, as running it damages the hub.

The 2023 Subaru Impreza is one of the models named in Subaru of America's WRN-23 safety recall. The defect is in the driveshaft's center support mounting: the support bolts may loosen, and if they do, the front end of the driveshaft can come disconnected from the car. NHTSA records the safety consequence as an increased risk of a crash. This is a manufacturing/assembly-related defect rather than an age-and-mileage problem, and Subaru's remedy addresses both the bolts themselves and the surfaces they clamp against. The recall covers 4,311 vehicles campaign-wide across all the Subaru models it includes — that total is not broken out by model, so it says nothing about how many Imprezas are involved.

Common Symptoms

  • Loosening of the driveshaft center support bolts
  • Disconnection of the front end of the driveshaft

How to Fix

Dealers perform the fix at no cost: they clean the bolt mounting surfaces on the driveshaft center support brace and install new bolts. Owner letters went out November 20, 2023. Whether or not you got one, check your VIN at nhtsa.gov/recalls against NHTSA campaign 23V647000 (Subaru recall WRN-23) and book the free repair at a Subaru dealer if your Impreza is listed. Subaru's customer service line for this recall is 1-844-373-6614.

Imprezas are highly susceptible to premature wheel bearing failure, often at 40,000-80,000 miles. The full-time AWD system adds constant load to all four wheel bearings. Rear bearings fail more frequently than fronts. Road salt, water, and debris accelerate bearing wear. Symptoms start as a subtle hum and progressively worsen to a loud growl. The noise is speed-dependent and may change when turning, helping identify which side is failing.

Common Symptoms

  • Progressive humming noise that increases with vehicle speed
  • Noise quiets when turning one direction and gets louder turning the other
  • Vibration felt through floorboard or steering wheel
  • ABS warning light illumination (wheel speed sensor affected)
  • Visible play when rocking the wheel at 12 and 6 o'clock positions

How to Fix

Replace the failed wheel bearing. Subaru Imprezas use hub-type bearings that require pressing out the old bearing and pressing in the new one. The steering knuckle must be removed. Use quality bearings: NSK 62BWKH19 (Subaru OEM supplier), Koyo DAC4584W-1CS81, or NTN AU0838-1LXL/L588. Replace in axle pairs for even wear. Torque specifications: front axle nut 162 ft-lbs, rear 140 ft-lbs.

Automatic-transmission 1990s Imprezas use the 4EAT with an electronically managed transfer clutch (governed by the Duty C solenoid) to split torque to the rear wheels. When the Duty C solenoid or its control valve sticks/leaks, or the transfer clutch pack wears, the AWD stays partially locked and the car binds during low-speed tight turns, producing a grabbing, grumbling shudder and drivetrain resistance. It is often misdiagnosed as a suspension or tire problem. A quick test: installing the FWD fuse that isolates the transfer clutch will make the bind disappear if the solenoid/valve is the cause.

Common Symptoms

  • Grabbing/grumbling and shudder during slow tight turns
  • Feeling of drivetrain resistance or binding when parking
  • Symptom eliminated when the FWD fuse is installed
  • Low-pitched driveline growl in both turn directions

How to Fix

Confirm with the FWD-fuse test. If solenoid-related, replace the relatively inexpensive Duty C transfer solenoid (and service the control valve) - this fixes the majority of cases caught early. If the transfer clutch pack is already worn, the extension housing/clutch pack must be rebuilt or the transmission replaced. Use only Subaru ATF and match tire circumference on all four corners to avoid re-inducing bind.

1993-1999 Imprezas (GC8/GF8/GM sedan, coupe, and wagon) are highly prone to corrosion at the rear wheel arches, rocker panels, and the rear subframe/crossmember, particularly in salted-road climates. The outer quarter panel and wheel housing are joined with spot welds and foam adhesive that are not water-tight, and the overlapping inner-arch seams trap dirt and moisture in a hard-to-access pocket, so rust blooms from the inside out; by the time paint bubbles the damage underneath is usually extensive. The rear subframe and its mounting bolts also corrode; seized or sheared bolts complicate suspension work and can be an inspection (MOT/state safety) failure. This is age- and environment-driven wear that now affects the majority of surviving northern-climate cars.

Common Symptoms

  • Bubbling paint and perforation at the rear wheel arches
  • Rusted-through rocker panels below the doors
  • Flaking, scaling rust on the rear subframe/crossmember
  • Seized or sheared subframe/suspension bolts
  • Safety-inspection failure for structural corrosion

How to Fix

Cut out rusted arch/rocker metal and weld in reproduction repair panels (widely available), then seam-seal, prime, and repaint. Treat cavities with wax/cavity rustproofing. For subframe corrosion, replace the subframe if structurally compromised and renew mounting bolts; soak/heat seized hardware to avoid shearing. Ongoing prevention: keep drain holes clear and undercoat.

The 2017+ Impreza (5th generation) uses a thinner, more aerodynamic windshield design that is highly prone to stress cracking, particularly around the EyeSight camera housing area. Cracks often appear spontaneously without any impact, starting from the edges or around the camera mounting bracket. Temperature changes exacerbate the issue. EyeSight-equipped vehicles require dealer recalibration ($200-400) after windshield replacement, adding significant cost.

Common Symptoms

  • Crack appearing from windshield edge with no visible impact point
  • Crack originating near EyeSight camera housing
  • Crack spreading rapidly across windshield
  • EyeSight system disabled warning after crack develops

How to Fix

Replace windshield with OEM Subaru glass or equivalent that meets EyeSight specifications. After installation, EyeSight camera recalibration is mandatory at a Subaru dealer (requires specialized targets and procedure). Some aftermarket glass does not meet the optical clarity requirements for EyeSight and can cause system malfunctions. Check comprehensive insurance — many policies cover glass with no deductible.

The 2012+ Impreza's Lineartronic CVT (TR580 for 2.0L models) is prone to harsh engagement, delayed acceleration response, and premature failure. The smaller TR580 CVT handles the 2.0L engine but can develop valve body issues causing harsh shifts into Drive/Reverse and a pronounced thunk when engaging gear from Park. The CVT chain can stretch, and the transmission oil pump can fail. Subaru extended the CVT warranty to 10 years/100,000 miles on affected models.

Common Symptoms

  • Harsh thunk when shifting from Park to Drive or Reverse
  • Delayed acceleration from a stop (2-3 second lag)
  • Shuddering at low speeds during light throttle
  • Transmission warning light illuminated
  • Metallic whining noise from transmission area
  • Vehicle surging or bucking at highway speeds

How to Fix

Begin with CVT fluid drain and refill using genuine Subaru CVT fluid. Have dealer check for and apply all available TCM software updates. Valve body replacement resolves harsh engagement in many cases. For complete CVT failure, a remanufactured CVT from Subaru costs less than a new unit. Verify 10-year/100,000-mile CVT warranty coverage before paying out of pocket.

The SOHC EJ18 and EJ22 engines in the base 1990s Impreza use a camshaft-driven distributor. With age, the cap and rotor corrode and crack, and the distributor O-ring can weep oil into the cap. This causes crossfire and weak spark that shows up as rough idle, hesitation, and hard starting, classically worse in damp or rainy weather when moisture inside the cap promotes arcing. It is an inexpensive but frequently overlooked maintenance item on these high-mileage cars.

Common Symptoms

  • Rough idle and intermittent misfire
  • Hesitation or stumble under acceleration
  • Hard starting or stalling, worse in wet/humid weather
  • Check-engine light with misfire codes (OBD-II cars)

How to Fix

Replace the distributor cap, rotor, and spark plug wires (and plugs) with quality parts; on OBD-II cars this clears random/cylinder misfire codes. If oil is found inside the distributor, replace the distributor O-ring/seal. Keep ignition components dry and correctly seated.
