• Owner complaints: No NHTSA complaints found for this make/model/year/issue combination in the provided data.
• What this means: There are no official recalls or reported complaints in the given data set to cite. The maintenance guidance here is based on general automotive best practice and Subaru’s typical service recommendations for this generation, not on any specific recall or complaint history.

Overview and approach

• Purpose: A practical, owner-focused maintenance schedule to help keep a 2012–2016 Subaru Impreza reliable, safe, and reasonably economical over the long term.
• Core philosophy: Regular inspections and timely service at reasonable intervals tend to prevent expensive repairs and keep performance consistent. The guide uses conservative, commonly accepted intervals that match Subaru’s typical recommendations for this generation.
• Vehicle scope: Applies to common 2012–2016 Impreza configurations (2.0L engine, manual/automatic/transmission options, and common AWD configurations). If your car uses a CVT, some service intervals (particularly for transmission fluid) may differ slightly from manual/old-school automatics. Always consult your owner’s manual for model-specific intervals.

Key maintenance items you’ll see in this schedule

• Engine oil and filter changes (synthetic recommended)
• Engine air filter and cabin air filter replacements
• Tire maintenance: rotations, balancing, tread depth checks
• Brakes and brake fluid checks
• Fluids: coolant, transmission (automatic/CVT or manual), differential (AWD), power steering, windshield washer
• Spark plugs (service intervals)
• Belts/hoses and battery checks
• Optional injector/fuel system care and seasonal checks
• Seasonal checks: cold-weather readiness, visibility, wiper blades

Maintenance intervals by mileage (general guidance)
Note: The following intervals reflect typical Subaru guidance for this generation and broadly accepted maintenance practice. If your owner’s manual indicates different intervals for your exact configuration, follow those specifications.

0–30,000 miles (0–48,000 km)

• Engine oil and filter: Inspect at every driving session; change every 7,500 miles under normal conditions with synthetic oil, or every 3,750–5,000 miles if your driving qualifies as severe (short trips, cold climates, lots of idling, heavy city driving).
• Tire rotation: Check and rotate every 5,000–7,500 miles (or with each oil change if you prefer a simple rule).
• FLUIDS: Check levels (coolant, brake, power steering, windshield washer). Top off as needed.
• Engine air filter: Inspect; replace if dirty. Typical replacement interval is around 30,000–60,000 miles depending on driving conditions.
• Cabin air filter: Inspect; replace around 15,000–30,000 miles, sooner in dusty or urban environments.
• Wiper blades and battery: Inspect, replace as needed; consider a battery test if the car sits unused for extended periods.
• Visual inspection: Belts, hoses, brake pads, rotors, suspension components, and exhaust system.

30,000–60,000 miles (48,000–96,000 km)

• Oil and filter: Follow the earlier interval guidance for your oil plan (synthetic oil often allows 7,500-mile changes; more frequent changes if you use conventional oil or have severe driving conditions).
• Tire rotation: Every 5,000–7,500 miles.
• Engine air filter: Replace around 30,000–60,000 miles (sooner if you drive in dusty areas).
• Cabin air filter: Replace around 15,000–30,000 miles; many owners choose around 30,000 miles.
• Spark plugs: Generally around 100,000 miles for many 4-cylinder Subarus of this era; if you’re approaching 60,000 miles and your plugs are original, plan for inspection and possible replacement at or near 60,000–90,000 miles depending on plug type and condition.
• Coolant: Inspect coolant level and cooling system condition; flush/replacement commonly recommended around 100,000 miles or every 5–7 years, whichever comes first. If you’re at 60k–80k, you may plan for a coolant check and schedule at 100k.
• Transmission fluid (automatic/CVT or manual): Inspect level and condition; many owners replace at around 60,000 miles for automatics. If you have a CVT, follow the CVT-specific service interval and use Subaru-approved CVT fluid. If you own a manual, check the clutch and gearbox condition and consider a service if there are grinding or synchro issues.
• Differential fluids (AWD): Inspect and consider a change around 60,000 miles; follow AWD differential service guidance from Subaru for your exact model.
• Brake fluid: Typically every 2–3 years (even if the mileage is low) due to moisture absorption; plan a brake fluid flush around the 2–3 year mark.
• Belts and hoses: Inspect serpentine belt(s) and hoses; replace if signs of wear, cracks, or glazing are present. Replace based on wear rather than a fixed mileage if you see wear.
• Brakes: Inspect pads and rotors; replace pads if below ~2–3 mm of pad material; rotors if warped or grooved.

60,000–90,000 miles (96,000–144,000 km)

• Oil and filter: Continue with normal interval (7,500 miles for synthetic; 3,750–5,000 for severe driving).
• Spark plugs: If you didn’t replace at 60k and you’re approaching 100k, plan for replacement around 90k–100k miles (check your plug type; many are long-life but verify with your service manual).
• Coolant flush/replacement: Plan around 100,000 miles; if you’re at 90k, schedule a coolant flush at or near 100k.
• Transmission fluid: If you have an automatic or CVT, follow the recommended CVT service interval and use the correct fluid. Consider a drain-and-fill or a full flush depending on your preferred service level and the recommendation for your vehicle.
• Differential fluids: Inspect and replace around 60,000–100,000 miles depending on usage and Subaru guidance.
• Brake fluid: Re-check and flush if due (typical interval every 2–3 years).
• Belts/hoses: Inspect the serpentine belt and replace if wear is evident.
• Suspension components: Inspect shocks/struts, control arm bushings, and related bushings; replace as needed if there’s noticeable wear or leaking.

90,000–120,000 miles (144,000–192,000 km)

• Oil and filter: As above; ensure consistent synthetic oil changes.
• Spark plugs: If not already replaced around 100k, plan replacement by 100k–105k miles (verify with exact plug type).
• Coolant: Plan replacement around 100k miles if not already done; establish a 5-year cadence thereafter.
• Transmission fluid: Follow CVT/manual guidelines; if you haven’t changed it recently, a service may be prudent.
• Differential fluids: Check and replace per AWD guidance.
• Brakes: Inspect pads, rotors, and brake lines; replace as needed.
• Belts/hoses: Inspect belts for cracking or glazing; replace if needed.
• Battery: Test battery health; replace if it shows signs of weakness.

120,000+ miles

• Oil and filter: Regular synthetic changes.
• Spark plugs: If not already done, replace as needed (many engines are rated for 100,000 miles or more; check your plug type and condition).
• Coolant: If not replaced recently, perform a coolant flush; plan for post-120k service cadence.
• Transmission fluid and differential fluids: Ensure fluids are clean and at the proper levels; replace per guidance.
• Brakes: Replace pads/rotors as wear dictates; inspect brake lines for corrosion.
• Tires: Replace as needed to maintain safe grip and adequate tread depth.
• Overall: Comprehensive multi-point inspection; address any suspension, steering, or driveline issues promptly.

Seasonal and condition-based checks (apply year-round)

• Winter readiness (cold climates): Verify battery health, charging system, antifreeze/coolant strength (specific gravity), windshield wiper blades suitable for winter, and proper tire tread depth or consider winter tires.
• Summer readiness: Check cooling system, cooling fans, thermostat operation, and ensure no leaks; ensure AC performance is efficient.
• Pre-trip checks: Fluid levels (oil, coolant, brake fluid, transmission fluid if applicable), tire pressure (adjust for load), spare tire condition, and a basic visual inspection of belts and hoses.
• Vehicle health monitoring: If you notice rough idling, misfires, reduced power, unusual noises, or warning lights, have the vehicle inspected promptly.

Common maintenance tasks explained (practical rationale)

• Engine oil and filter: Oil lubricates engine parts; newer synthetic oils provide good protection at extended intervals. Regular changes protect bearings, reduce sludge, and keep engine life longer.
• Air filters: Clean air improves combustion efficiency and engine performance; a clogged air filter reduces power and fuel economy.
• Cabin air filter: Keeps interior air clean and reduces allergens; replace to maintain HVAC efficiency.
• Spark plugs: Spark plug condition affects ignition timing, smooth running, and fuel economy. Worn plugs can cause misfires and reduced performance.
• Coolant and cooling system: Prevents overheating and protects metal parts from corrosion. A degraded coolant can lead to overheating and costly damage.
• Transmission fluid: Lubricates and cools the transmission; contaminated or degraded fluid can cause shifting issues or early wear.
• Differential fluid: In AWD/Subaru systems, differential fluid helps lubricate gears and ensures smooth power transfer. Contamination or loss of lubrication can cause drivetrain noise or damage.
• Brakes: Regular inspection and timely pad/rotor replacement maintain stopping power and safety.
• Belts and hoses: Worn belts can fail and leave you stranded; hoses can leak or fail under pressure.
• Battery: A reliable battery prevents breakdowns and starting issues, especially in extreme temperatures.

Model-year notes and considerations (2012–2016 Impreza)

• These model years generally share similar engine layouts and drivetrain components; differences between 2012, 2013, 2014, 2015, and 2016 are typically refinements or option-level variations rather than fundamental changes to the maintenance schedule.
• If your car uses a CVT or a traditional automatic transmission, follow the transmission-specific service intervals and the Subaru-approved fluid type for CVTs (which differ from conventional automatics).
• Timing: Subaru Impreza engines of this era use timing chains rather than timing belts, so routine timing belt replacement is not part of the regular maintenance schedule. Still, have timing-chain tensioners and related components inspected if you hear unusual engine noises or suspect slack in the chain.
