Used Subaru Impreza 5th Gen (2017-2023): Buyer's Guide

The 2019 Subaru Impreza has 189 NHTSA complaints on file. The 2022 has 12. Same engine. Same Subaru Global Platform. Same basic shape. But the 2022 has a properly debugged ECM, a windshield class action in the rearview, a suspension revision under it, and EyeSight standard on every CVT trim. The year you pick inside this generation matters more than the model itself.

This guide covers the 5th generation Impreza specifically: the SGP-era cars from 2017 through 2023. Not the WRX. Not the Crosstrek. The base Impreza, which shares the platform but has its own reliability story, its own recall history, and its own buyer traps.

This Generation at a Glance

The 5th gen Impreza was the first Subaru built on the Subaru Global Platform. Developed over four years at a cost of $1 billion, SGP brought a 70% increase in torsional rigidity over the previous generation and a lower center of gravity. The result is a noticeably better-riding, better-handling car than the 4th gen it replaced.

The generation runs 2017 to 2023. A meaningful mid-cycle refresh arrived for 2020: updated front fascia, new wheel designs, revised suspension tuning for a more compliant ride, new interior materials, and EyeSight driver assistance standard on every CVT-equipped trim. The 6th generation arrived for 2024 on a further-evolved SGP.

Body styles: 4-door sedan and 5-door hatchback. Both are available in all trims. The 5-door is more practical and most buyers prefer it.

The manual transmission is only available on the Sport trim. It also drops AWD entirely, making the car front-wheel drive. Most buyers considering the Impreza are here because of AWD. If that's you, the CVT is your only real choice.

Powertrain and Trim Breakdown

FB20 CVT (AWD) — The Car Most People Buy

The vast majority of 5th gen Imprezas on the used market are CVT-equipped AWD cars. That's the right choice for most buyers, but it comes with specific things to check.

Oil consumption and the PCV valve recall (2017-2018)

The FB20 in 2017 and 2018 models shipped with a PCV valve that used a plastic internal mechanism. Under normal operation, the valve allowed engine oil to enter the intake and combust, causing white exhaust smoke and measurable oil loss. Subaru addressed this with a recall — TSB 02-175-18 — replacing the plastic-valve PCV with an all-metal version that seats more reliably. If you're buying a 2017 or 2018, your first job is verifying this recall was completed. Enter the VIN on NHTSA.gov or run it through CarScout's recall checker before anything else.

The updated PCV valve largely resolved the issue on affected cars. On unrepaired examples, owners on impreza5.com report consuming a quart of oil every 1,000-3,000 miles. That's not normal. That's a drain-and-refill lifestyle.

VVT / AVCS codes (P0018, P0011)

DTC P0018 is the most frequently reported trouble code across 2017-2018 Imprezas. It indicates a crankshaft-to-camshaft timing correlation fault, typically from a failed oil control valve inside the AVCS variable valve timing system. The OCV itself costs $80-200 in parts, but with diagnosis and labor, a full repair typically runs $300-600. TSB 09-120-24R calls for an ECM reprogram on affected 2017-2020 models as part of the fix.

The VVT system runs on engine oil pressure. Every VVT code that starts with poorly maintained oil ends the same way: an OCV starved of clean fluid eventually sticks or fails. If you're buying any 5th gen Impreza, ask about oil change history. A car with 80,000 miles and no oil service records is the highest-risk version of this issue.

CVT longevity

Subaru classifies the CVT fluid as "lifetime," meaning they don't publish a mandatory change interval for the US market. Owners on impreza5.com and Subaru-related forums consistently disagree. Forum consensus lands on a drain-and-fill every 30,000-40,000 miles, with most experienced owners crediting that interval for CVT life past 150,000 miles. A single fluid service runs $150-200 at a dealership.

When inspecting a used 5th gen, ask for the transmission service history. If you're looking at a car with 80,000+ miles and no CVT fluid on record, that's a $150 service you'll want done immediately and a question about what else was deferred.

Subaru extended the CVT warranty to 10 years or 100,000 miles on many 2012-2017 models following earlier-generation reliability concerns. Some 2017 CVT Imprezas still fall within that window. Verify the warranty status on any 2017 purchase before closing the deal.

EyeSight reliability

EyeSight became optional on Sport and Limited trims in 2017, expanded to more trim configurations in 2018-2019, and became standard on every CVT trim starting in 2020. The system uses two forward-facing cameras mounted near the rearview mirror.

Owners on the Subaru forums report two EyeSight failure modes. The first is environmental: condensation on the camera lens causes temporary shutoffs, especially in cold or humid weather. This resolves with the defroster on. The second is hardware failure. At high mileage, owners report the cameras failing outright. A replacement runs approximately $3,700. If you're buying a 2017-2019 car with EyeSight at 100,000+ miles, factor that potential cost into your offer. On the test drive, turn on the ignition and confirm EyeSight initializes without warning lights. Test it on the road if possible.

EyeSight randomly shutting off during a test drive is normal: the system self-protects when it can't see clearly. Warning lights staying on in normal daylight conditions are not normal.

Windshield cracking

A class action lawsuit covers 2017-2020 Subaru Impreza models (along with Outback, Forester, Crosstrek, and Legacy on the same platform) for a windshield defect. The ceramic border material around the perimeter of the windshield, combined with the heat from the wiper deicer element, creates a thermal stress concentration. Cracks typically originate at the lower edge near where the defroster meets the glass. TSB 12-192-15R acknowledged the root cause. The warranty portion of the class action was dismissed, but the pattern is real and documented across hundreds of owner complaints.

On any 2017-2020 Impreza inspection, get on your knees and look at the lower windshield edge directly. Any crack starting near the defroster line will spread. A replacement windshield runs $350-700 depending on whether EyeSight recalibration is required. EyeSight-equipped cars need camera recalibration after windshield replacement, adding $150-300 to the bill.

FB20 Manual (FWD) — Sport Trim Only

The Sport is the only trim that offers a manual transmission. Choosing it means giving up AWD entirely: manual Imprezas are front-wheel drive.

That's a significant trade-off for a brand where AWD is the primary selling point. Forum owners who've owned both confirm it: the AWD CVT Sport is more capable in winter than the FWD manual Sport, even with winter tires. If you're choosing the manual for driver engagement in a state that gets real snow, you're making a compromise the platform wasn't designed for.

The manual Impreza also has more severe oil consumption than CVT versions. Owners on impreza5.com observe that engine braking and higher-rev driving cycles pull more oil through the PCV system. TSB 02-175-18 applies specifically to manual-transmission cars. The PCV valve update is more critical on a manual than on a CVT car.

What the Sport trim gets you besides the manual: sport-tuned suspension, 18-inch alloy wheels, Active Torque Vectoring (on AWD Sport with CVT), aluminum sport pedals, and a more aggressive interior presentation. If you choose the Sport CVT instead of the Sport manual, you get AWD plus most of the Sport's equipment.

The manual Impreza Sport is for people who genuinely prefer a stick and accept the FWD compromise. It's a driver's car in a compact, practical package. It just isn't an AWD car.

Trim-Specific Notes

2.0i Base: CVT, AWD, 17-inch steel wheels on base, STARLINK 6.5-inch infotainment. No heated seats, no EyeSight before 2020. The no-frills choice. Starting price in used market makes it the budget pick.

2.0i Premium: Adds 17-inch alloys, heated front seats, fog lights, and the 8-inch StarLink infotainment. This is the sweet spot for most buyers. You get the practical upgrades without the complexity of the top trims.

2.0i Sport: Sport-tuned suspension, 18-inch wheels, available in 5-door body, option of manual or CVT. Worth seeking out for the suspension alone if ride is a priority. The AWD Sport with CVT is the best balance in the lineup.

2.0i Limited: Full leather interior, EyeSight standard from 2019 onward, power driver seat, proximity key with push-button start. The EyeSight standard equipment on 2019+ Limited trims is a meaningful safety upgrade. After 2020, all CVT cars get EyeSight, making the Limited's safety premium disappear and shifting its value to interior quality alone.

The 5-door hatchback body style costs slightly more than the equivalent sedan. It is worth it. The rear cargo floor is at bumper height, loading is easier, and the hatch silhouette holds up better over time. Many owners who bought the sedan wish they had bought the 5-door.

Which Model Years to Target Within This Generation

The 2020 is the best value inside this generation. It gets the mid-cycle refresh, EyeSight standard on every CVT trim, zero formal recalls, and a suspension tune that makes the ride measurably more comfortable than pre-refresh cars. Prices are lower than 2022 because there are more of them.

The 2022 is the cleanest car on paper. Only 12 total NHTSA complaints for the entire model year. Pricing reflects its scarcity in used inventory.

Avoid 2017. Seven recalls is a lot for any car, and the combination of PCV issues, ECM software problems, and VVT codes makes early production 2017 Imprezas the highest-risk cars in the generation. A well-maintained 2017 with full service records and verified recall completion is manageable, but pay accordingly.

Avoid 2019 despite its low formal recall count. The 189 NHTSA complaints are the tell. Complaints reflect owner frustration that didn't reach recall thresholds: ECM-related stalls, headlamp failures, electrical gremlins, and windshield issues. The difference between a 2019 and a 2020 in used prices is often under $1,500. The 2020 is worth the premium.

Pre-Purchase Inspection Checklist

For 2017-2018 models:

• Before the test drive, enter the VIN on CarScout's recall lookup or NHTSA.gov. Confirm the PCV valve recall (TSB 02-175-18) was completed. If the dealer can't confirm it, budget for the update and ask for a price concession.
• Start the car cold. Watch the exhaust at startup for white or bluish smoke. A brief puff is normal. Smoke that persists past 30 seconds or recurs at idle suggests oil consumption that the PCV recall may not have fully resolved.
• On a cold start, listen for a metallic tick or rattle in the first 30 seconds that fades as the engine warms. A tick that does not fade at operating temperature can indicate P0018 VVT/OCV issues. Have a mechanic scan for codes before buying any high-mileage 2017-2018.

For CVT-equipped cars (all years):

• Ask for transmission service records. If the car has 60,000 or more miles with no CVT fluid service on record, budget $150-200 and do it immediately. Treat the missing service as a negotiating point.
• On the test drive, the CVT should accelerate smoothly from a stop. Any jerking, shuddering, or unexpected RPM surge under moderate acceleration is a red flag.

For EyeSight-equipped cars (2017-2019 Limited/Sport, all CVT 2020+):

• At the start of the test drive, verify EyeSight initializes without warning lights. If it shows a camera error in normal daylight conditions, the cameras need service.
• On the highway portion of the test drive, verify lane centering and adaptive cruise work. A system that constantly turns off is not normal in clear weather.

Windshield and body check:

• Crouch down at the front of the car and look along the lower windshield edge where the defroster vents meet the glass. Any crack starting at the black ceramic border near the bottom edge will spread. This is not a chip from road debris. The failure pattern starts at the defroster line.
• If the windshield is cracked and the car has EyeSight, a replacement runs $500-1,000 including camera recalibration. Factor that into your offer.

All cars:

• Check all four tires for matching brand and tread depth. The AWD system requires tires within 2/32-inch of each other. Mismatched tires indicate deferred maintenance and can damage the center differential. A full set of four tires costs $600-1,200.
• Operate all four windows and the rear wiper. Check that the rear defroster clears glass in 10-15 minutes.
• Test the infotainment. The StarLink system in 2017-2019 cars has a reputation for occasional freezes and unresponsive touchscreens, though it rarely affects drivability.

Running Costs

The FB20 uses a timing chain rather than a rubber belt. There is no timing belt replacement interval. This is a meaningful advantage versus many competitors that require a $600-1,200 belt service at 90,000-100,000 miles.

AWD cars have a tire cost that owners sometimes don't anticipate: all four tires must remain matched in brand and tread depth. Replacing one corner often means replacing all four. Budget $600-1,200 every 40,000-60,000 miles for tires, depending on the brand and trim's wheel size.

Annual fuel cost for the CVT at 15,000 miles per year: approximately $2,100-$2,400 at $3.50/gallon. The manual's 27 mpg combined adds roughly $200-300 per year in fuel costs versus the CVT.

EyeSight camera replacement if needed at high mileage: approximately $3,700. This cost doesn't apply to all cars, but it's worth knowing before you prioritize EyeSight-equipped inventory.

FAQ

Is the 5th gen Subaru Impreza reliable? It's reliably average. Annual repair costs run about $653 versus the $526 industry average for compact cars. Early years (2017-2019) had documented ECM, PCV, and VVT issues. The 2020-2022 model years are significantly cleaner. With regular CVT fluid changes every 30,000-40,000 miles, 150,000-200,000 miles is achievable. The FB20's timing chain instead of a belt removes one major maintenance cost.

Which year 5th gen Impreza is best? The 2020 is the best value: zero recalls, mid-cycle refresh with updated styling and suspension, and EyeSight standard on all CVT trims. The 2022 is the cleanest year in the generation with only 12 NHTSA complaints on record. Avoid 2017 (7 recalls, first-year VVT and PCV issues) and 2019 (189 NHTSA complaints, the highest of any 5th gen year).

Does the 5th gen Impreza have a timing belt? No. The FB20 uses a timing chain, not a rubber belt. There is no timing belt replacement interval. This eliminates a $600-1,200 service that many Japanese competitors require at 90,000-100,000 miles.

Is the manual transmission Subaru Impreza AWD? No. The manual transmission is only available on the Sport trim, and it makes the car front-wheel drive. Every AWD Impreza in this generation uses the CVT. If you want AWD with a manual gearbox, the Subaru WRX is the correct car.

How long does the Subaru Impreza CVT last? With fluid changes every 30,000-40,000 miles, owners report 150,000+ miles without major issues. Subaru extended CVT warranty to 10 years or 100,000 miles on 2012-2017 models. One owner on impreza5.com reported a CVT replacement at 85,000 miles under the extended warranty, with no further transmission issues afterward. The key variable is maintenance: the "lifetime fluid" designation Subaru uses is not a recommendation, it's a cost-cutting specification.

Bottom Line

The 2020-2022 5th gen Impreza CVT is the sweet spot. Zero recalls, standard EyeSight across the lineup, a suspension that rides better than early-gen cars, and AWD traction that owners consistently rate as the car's best attribute. The 5-door body adds practical value. Pay the premium for it.

Before buying any 5th gen, run the VIN through a recall check at /tools/recall-lookup. On a 2017 or 2018, confirm the PCV valve recall was completed before you finalize anything.
