The 1996 Impreza represents first-generation EJ-series Subaru reliability with typical head gasket vulnerabilities and some transmission cooling concerns. Generally solid daily drivers when maintained, but budget for the inevitable head gasket job.
Head Gasket Failure (2.2L EJ22 engines)
Common · high severityTypical onset: 100,000-150,000 mi
Symptoms: External coolant seepage at block/head mating surface, often visible as crusty residue, Overheating under load or gradual coolant loss without visible leaks, White exhaust smoke or milky oil in severe cases (less common on EJ22), Bubbling or pressurization in coolant reservoir
Fix: Full head gasket replacement both sides, resurface heads if warped, replace timing components and water pump while apart. 12-16 labor hours depending on experience and complications. The 2.2L is less prone to internal failure than later 2.5L engines but external seepage is still typical.
Estimated cost: $1,800-2,800
Automatic Transmission Oil Cooler Line Corrosion
Common · medium severityTypical onset: 80,000-140,000 mi
Symptoms: Transmission fluid pooling under vehicle, often near radiator area, Rust-through or pinhole leaks in steel cooler lines, Delayed engagement or slipping if fluid level drops significantly, Visible corrosion on lines running from transmission to radiator
Fix: Replace both cooler lines and affected fittings; upgrade to braided stainless if available. Flush transmission and refill with Dexron III. 2-3 labor hours. Salt-belt cars see this earlier and more severely.
Estimated cost: $300-550
Front Engine/Transmission Mount Deterioration
Common · low severityTypical onset: 90,000-130,000 mi
Symptoms: Excessive vibration at idle, especially in Drive with A/C on, Clunking when shifting from Park to Drive or Reverse, Visible tearing or oil saturation in rubber mount sections, Engine rocks noticeably under throttle application
Fix: Replace pitch stopper mount and front transmission mount as a pair. OEM or quality aftermarket critical here—cheap mounts fail in under a year. 2-3 labor hours total.
Estimated cost: $250-450
Fuel Filter Clogging (carbureted models or early EFI)
Occasional · medium severitySymptoms: Stumbling or hesitation under acceleration, Hard starting after sitting, especially when warm, Loss of power at highway speeds or under load, Engine stalling at idle after spirited driving
Fix: Replace inline fuel filter, inspect fuel pump sock filter if accessible. On '96s this is typically 0.5-1 labor hour. Often overlooked maintenance item—should be changed every 30k miles.
Estimated cost: $80-150
Rear Wheel Bearing Failure
Occasional · medium severityTypical onset: 110,000-160,000 mi
Symptoms: Grinding or humming noise from rear that increases with speed, Noise may change pitch or volume during turns, Excessive play in wheel when jacked up and wiggled at 12-6 o'clock, ABS light may illuminate if equipped and sensor damaged
Fix: Replace wheel bearing assembly or press out and replace bearing/race depending on design. Requires hub removal. 2-2.5 labor hours per side. AWD system stress accelerates wear.
Estimated cost: $300-500 per side
Headlight Circuit/Switch Failure (NHTSA recalls)
Occasional · high severitySymptoms: Headlights intermittently fail to turn on or flicker, Combination switch overheating or melting at connector, One or both headlights out despite new bulbs, Burning smell from steering column area
Fix: Check for open recalls (NHTSA campaigns for headlight issues). Replace combination switch assembly and repair wiring harness connector if melted. 1.5-2.5 labor hours including diagnostics.
Estimated cost: $200-400
Exhaust System Rust-Through (donut gasket and Y-pipe)
Common · low severityTypical onset: 70,000-110,000 mi
Symptoms: Loud exhaust noise from engine bay, especially on cold start, Ticking or popping sounds that follow engine RPM, Visible rust perforation or cracking at Y-pipe to head connection, Failed emissions test due to pre-cat leaks
Fix: Replace donut gaskets where headers meet Y-pipe, or replace entire Y-pipe if rotted. Often need to cut rusted studs and install new hardware. 2-3 labor hours. Rust-belt endemic.
Estimated cost: $300-600
Solid buy for a budget AWD platform if head gaskets are documented as done or you budget $2k for the inevitable job—mechanically simple and parts are cheap.
