2017 Subaru Impreza Maintenance Schedule
- Generation
- GT/GK (5th gen, first year)
- Engine
- 2.0L naturally aspirated flat-4 (FB20)
- Intervals
- 13
The 2017 Subaru Impreza marks the first year of the all-new GT/GK fifth generation, featuring the FB20 2.0L flat-four engine with standard Symmetrical All-Wheel Drive and a timing chain (no belt replacement needed). This schedule addresses the unique needs of Subaru's boxer engine layout and CVT transmission where equipped, emphasizing fluid maintenance critical to AWD longevity and the CVT's durability.
Service Intervals
Where is your Impreza right now?
Type the odometer and the table below re-sorts by what's closest. It works from the reading alone — it can't see what you've already had done.
Est. costs are US-typical, in USD.
| Service | Interval | Est. Cost |
|---|---|---|
| Engine Oil & FilterSafety itemSubaru specifies 0W-20 synthetic oil; boxer engine design makes oil quality critical for horizontal cylinder lubrication. | 6,000 mi / 6 mo | $45-$75 |
| Tire RotationSafety itemAWD system requires even tire wear across all four corners to prevent drivetrain binding and center differential damage. | 7,500 mi | $25-$50 |
| Cabin Air FilterLocated behind glove box; affects HVAC performance and air quality in the cabin. | 12,000 mi / 12 mo | $20-$45 |
| Engine Air FilterInspect at every oil change; replace when visibly dirty or at 30k miles to maintain fuel efficiency. | 30,000 mi | $25-$50 |
| Brake Fluid FlushSafety itemSubaru specifies DOT 3 or DOT 4; hygroscopic fluid degrades over time regardless of mileage. | 36 mo | $80-$130 |
| Brake Pad Inspection & ReplacementSafety itemInspect every 15k miles; AWD weight and boxer engine braking characteristics can accelerate front pad wear. | 30,000 mi | $150-$350 |
| CVT Transmission Fluid (if CVT-equipped)Safety itemSubaru Lineartronic CVT fluid (TR580) required; Subaru lists inspection under normal duty, with replacement for severe-duty use such as towing or mountain driving. | 60,000 mi | $180-$300 |
| Manual Transmission Fluid (if manual-equipped)Subaru Extra S 75W-90 gear oil specified; protects synchros and extends transmission life. | 60,000 mi | $90-$150 |
| Rear Differential FluidSafety itemThe rear differential carries its own gear oil; on CVT cars the front differential shares fluid with the transaxle and the center coupling is an electronically controlled clutch inside the CVT. | 60,000 mi | $120-$200 |
| Engine Coolant FlushSubaru Super Coolant initial change at 137,500 miles, then every 75,000 miles; protects aluminum heads and boxer engine's horizontal cooling passages. | 137,500 mi / 132 mo | $120-$180 |
| Spark PlugsSubaru specifies spark plug replacement every 60,000 miles on the FB20; boxer layout makes access labor-intensive, especially on the passenger side. | 60,000 mi | $150-$250 |
| Battery Inspection & ReplacementTest annually after three years; Subaru's AWD system and electronics place higher demands on battery. | 48 mo | $150-$250 |
| Wheel Alignment CheckAWD drivetrain is sensitive to alignment; misalignment causes uneven tire wear and potential center diff stress. | 30,000 mi | $80-$150 |
2017 Subaru Impreza Oil Change Interval
The 2017 Subaru Impreza oil change interval is every 6,000 mi or 6 months, whichever comes first (estimated cost $45-$75). Subaru specifies 0W-20 synthetic oil; boxer engine design makes oil quality critical for horizontal cylinder lubrication.
What Happens If You Skip It
- Neglecting CVT fluid changes beyond 60k miles can lead to shuddering, slipping, and catastrophic transmission failure costing $4,000-$7,000 to replace.
- Mismatched or unevenly worn tires (more than 1/4-inch tread difference) force the AWD system to work constantly, overheating and damaging the center differential.
- Deferred oil changes allow sludge buildup in the FB20's horizontal cylinders, starving bearings and potentially causing rod knock or spun bearings.
- Skipping differential fluid services leads to metal shavings circulating through the AWD system, resulting in grinding, binding, and eventual differential failure.
- Ignoring brake fluid flushes allows moisture absorption, reducing boiling point and causing brake fade or complete pedal loss under hard braking.
Common Issues at Higher Mileage — 2017 Subaru Impreza
CVT judder or hesitation during acceleration, often traced to degraded transmission fluid or worn valve body components.
Wheel bearing noise (humming or growling) becomes common, particularly on rear wheels due to AWD constant engagement.
Head gasket seepage may appear on FB20 engines, though less severe than older EJ-series; watch for coolant smell or minor external leaks.
Front lower control arm bushings wear, causing clunking over bumps and imprecise steering feel.
Brake rotor warping can occur if pads are not replaced promptly, causing pulsation during braking.
Oxygen sensor degradation may trigger check engine light and reduce fuel economy; upstream sensors typically fail first.
Common questions about the 2017 Subaru Impreza
How often does a 2017 Subaru Impreza need an oil change?
The 2017 Subaru Impreza oil change interval is every 6,000 mi or 6 months, whichever comes first (estimated cost $45-$75). Subaru specifies 0W-20 synthetic oil; boxer engine design makes oil quality critical for horizontal cylinder lubrication.
What maintenance does a 2017 Subaru Impreza need?
The services not to skip on a 2017 Subaru Impreza: engine oil & filter every 6,000 mi / 6 mo; tire rotation every 7,500 mi; brake fluid flush every 36 mo; brake pad inspection & replacement every 30,000 mi; cvt transmission fluid (if cvt-equipped) every 60,000 mi.
