What are common problems with Subaru Impreza?

[LeWyatt]

The most common Subaru Impreza problems are excessive engine oil consumption in 2012-2016 models, head gasket failures in pre-2012 2.5L engines, and CVT transmission issues in 2011-2017 models. Owners also frequently report premature suspension wear, electrical glitches, and rust, particularly on rear wheel arches. Models from 2008-2013 are often flagged by reliability surveys as having higher overall failure rates.

A core issue is engine oil consumption. Data from a 2015 class-action lawsuit and subsequent warranty extension confirmed that certain FB-series engines in 2011-2015 models could consume over 1 quart of oil per 1,000 miles—far above industry norms. This is often linked to faulty piston rings. Oil leaks from the rear main seal, camshaft, and crankshaft seals are also prevalent in higher-mileage examples.

Head gasket failure is a notorious problem for Imprezas equipped with the EJ25 engine, common in models built before 2012. The failure typically causes external coolant leaks and potential overheating. Repair is labor-intensive, often costing over $2,000. Subaru addressed this in later FB engine designs, making it less frequent in post-2012 vehicles.

The Continuously Variable Transmission (CVT) is another concern. Models from the 4th generation (2011-2017) can exhibit shuddering, jerking, or whining noises. In severe cases, this leads to complete failure. Subaru extended the CVT warranty to 10 years/100,000 miles for 20121-2017 models in response, a clear indicator of a recognized pattern.

Electrical and infotainment problems are widespread. These range from faulty brake light switches (prompting official recalls) and knock sensor failures to software glitches in the STARLINK system, causing screen freezes or connectivity loss.

Suspension and steering components, such as sway bar end links and wheel bearings, tend to wear out sooner than on some competitors. Rust, especially on rear quarter panels and brake lines, is a known issue in regions that use road salt.

Problem Category	Most Affected Model Years	Key Symptoms/Notes
Engine Oil Consumption	2012-2016 (FB engine)	Burns > 1qt/1,000 miles; piston ring design flaw.
Head Gasket Failure	Pre-2012 (EJ25 engine)	External coolant leak, overheating risk.
CVT Transmission Issues	2011-2017	Shuddering, whining, potential failure; warranty extension exists.
Suspension Wear	All generations	Premature failure of sway bar links, wheel bearings.
Rust	All generations, especially older	Rear wheel arches, brake lines, undercarriage.

Proactive maintenance is crucial. Check oil levels every 1,000 miles for affected models. Have the CVT fluid inspected regularly, though Subaru may label it "lifetime." Address rust early with undercoating and wash the undercarriage frequently in winter. For pre-2012 models, verify if the head gaskets have been replaced with the updated multi-layer steel (MLS) type.

As a mechanic who sees a lot of Subarus, the Impreza’s issues are pretty predictable once they hit 80,000 miles or so. The big one I tell customers to watch for is oil consumption. People come in with a check engine light, and it’s often just low oil from burning it off. I’ve seen 2014-2015 models need a quart added between changes. The other job we do constantly is front sway bar links—they start clunking over bumps way sooner than they should. If you’re buying used, get it on a lift. Check for wetness around the rear of the engine block and look for crusty rust behind the rear wheels. Those are the money pits.

I’ve owned my 2014 Impreza for nine years now. It’s been reliable in the sense that it’s never left me stranded, but it demands attention. Yes, it uses oil—about a quart every 3,000 miles in my case. I just keep a spare in the trunk and check it every other fuel stop. The head unit is the other annoyance; the Bluetooth randomly disconnects and the screen can be slow to respond. On the plus side, the all-wheel drive is fantastic in snow. My advice? If you can handle the minor quirks and stay on top of fluid levels, it’s a solid car. Just go in with your eyes open to these known issues.

Shopping for a used Impreza? Focus your inspection on three things: model year, service history, and rust. Avoid the 2008-2013 years if you want fewer headaches. For any car, ask for records on timing belt changes (for older models) and CVT fluid service. Look under the oil filler cap for white sludge, which could indicate a failing head gasket. Check the trunk wheel well and rear quarter panels for bubbling paint—rust starts there. Test drive it thoroughly; listen for CVT whine during acceleration and feel for shuddering at low speeds. A pre-purchase inspection by a Subaru specialist is worth every penny.

From a long-term ownership cost perspective, the Impreza’s common problems translate into predictable expenses. The head gasket repair on an older model is a major outlay, often between $2,000 and $3,000. While less catastrophic, chronic oil consumption adds up in added oil and potential catalytic converter damage from excess oil burn. CVT failure, though covered under an extended warranty for some years, is a $7,000+ repair out of warranty. Factor in the propensity for suspension bushings and wheel bearings to need replacement more frequently than average, and your maintenance budget should be higher than for a Toyota Corolla. The key is preventive spending: addressing rust proofing early and adhering to stricter fluid change intervals for the CVT and engine oil can mitigate larger costs down the road.
