These checks are specific to this model year. For tires, body panels, fluids, and the other basics every used car needs, use the general inspection guide.

Which Impreza is it?

EPA figures for each version of the 2018 Subaru Impreza. Use them to confirm you are looking at the version that was advertised, and as a yardstick on the test drive.

VersionDriveEPA rating

  • Reset the trip computer at the start of the drive. A Impreza that averages well under the EPA 32 mpg combined on a mixed route may have an engine or tire problem.

Check the odometer against these mileages

Owners report these failures starting around the mileages below. A car inside one of these ranges deserves a closer look at that part, or records showing it was already fixed.

Why these checks: what owners reported

NHTSA complaints for the 2018 Subaru Impreza, grouped by the part owners named. Open a row to read what goes wrong.

  • Exterior lights621 crash

    Headlight recall work that cannot be finished makes up most of these reports. Owners say they were notified of a headlight recall, but dealers and the manufacturer confirm the parts are not available. Several have waited nearly two years. Few describe an actual failure, though some say the low beams are very dim at night. Owners with front-end collision damage hit a second problem: dealers and body shops won't replace a damaged headlamp while the recall is open, which keeps cars off the road for months. One report is tied to a crash.

  • Wipers and visibility34No crashes

    Windshields crack with no impact point, often while the car is parked overnight or during cold weather and defroster use. Cracks often start near the bottom edge or wiper area and spread across the glass within days. Some owners have replaced the windshield two or three times and paid about $1000 each time, because warranty and insurance did not cover it. Other complaints describe heavy chipping by 10,000 miles, and one describes a rear-view mirror that fell off and pulled a chunk of glass with it.

    Windshields crack with no visible impact, usually discovered after the car has been parked. Cracks can run about 30 inches and block the driver's view. One windshield shattered when water was poured on it to wash it. Reported mileages run from 16,000 to 81,500, and several fall near 25,000. Owners generally could not find a cause, and dealers sometimes send them to independent glass shops. One complaint covers a recall repair waiting on parts.

  • Electrical111 crash

    Batteries go dead over and over, leaving cars that won't start or jump, and some owners are on their third or fourth battery. Dealers often tell owners to drive more or buy a battery tender. In one case a parasitic draw test traced the drain to the Data Communications Module. The Starlink head unit reboots itself, drops Bluetooth, and shows a black backup camera screen. Other reports cover flickering lights, a failed starter, and an ignition key that won't turn. One crash report with an injury says the side airbags did not deploy.

  • Engine7No crashes

    Oil leaks and heavy oil burning lead to blue or dark smoke, power loss under acceleration, and quotes for major repairs or rebuilds above $5000. One owner says the engine began failing at 68k miles. Another reports overheating at 106,000 miles after a failed reseal. Other complaints describe spark knock the dealer called common, and an engine that died while slowing and took minutes to restart. A fire investigator reported a fatal fire that started in the engine compartment.

  • Transmission41 crash

    Cars stall at stop signs and traffic lights, and in one case the stalled car rolled backward toward another vehicle. Other owners report shuddering, hesitation, and intermittent power loss between 2000 and 3000 RPM that dealers can't reproduce across repeated visits. One car's engine failed climbing a hill and was replaced, but the stalling continued afterward. One crash report describes sudden acceleration at low speed while parking, with the car jumping a curb and hitting a tree without the airbags deploying.

  • Body and structure4No crashes

    The wiper cowl panel lifts away from the base of the windshield. The gap starts small and grows to about 1 inch at the center after driving. Water pours in through the gap during heavy rain, snow, or car washes, and leaves and pine needles get in and clog the drain tubes. Pushing the panel back down doesn't hold, and one panel warped again soon after a warranty replacement at low mileage. The remaining reports describe windshields cracking with no impact, including a replacement that cracked within a week in frost.

  • Brakes3No crashes

    Shaking and shuddering under braking is the main complaint. It shows up once the brakes are warm or at highway speed, and the vibration comes through the steering wheel into the cabin. Owners say it continues even after new pads and rotors, and one describes the car pulling as if a front brake were grabbing. Another report describes brakes squealing at about 20,527 miles that took repeated dealer visits to fix. Owners describe the shaking as getting worse and unsafe at speed.

  • Steering2No crashes

    The tilt steering column doesn't lock firmly, so the wheel shifts up or down while driving even with the lever engaged. One such report comes from a car under 40k miles that also had water leaking in through clogged drains. A second complaint describes a rubbing noise when braking in turns, vibration at higher speeds, and shifting trouble that the dealer could not find.

In owners' own words

Excerpts from complaints Impreza owners filed with NHTSA, as written. Listen for the same symptoms on your test drive.

Exterior lightsCrash reported
My car was involved in an accident and one headlight was smashed. I found out from my body shop that was my car was recalled and they have no way to fix my headlight. I called Subaru and they told me that the body shop could just put another head light in. But when I talked to the body shop, they cannot just put a headlight in because of the recall. No one is able to help me and now I am out of a car for months instead of only one month.

Filed with NHTSA, December 2022

Exterior lights
It has been over a year since the recall was issued for my vehicle. Subaru has yet to make the remedy available in my area. It’s been over a year now and Subaru dealerships near me say that they still have no idea of when the remedy will become available. I replaced my driver side headlight assembly shortly before the recall was issued. Subaru informed me that I could receive a refund for the part that I paid for (headlight assembly) due to the recall.

Filed with NHTSA, August 2023

Wipers and visibility
Windshield cracked for not apparent reason. Parked car, places visor up, came back to car, took visor down and immediately noticed the crack. I do not remember any rocks hitting the windshield at that spot and I did not notice it at all until this morning when returning to my car. Very unusual.

Filed with NHTSA, March 2022

Electrical
When the car is turned on, all of the lights flicker nonstop to the point of moderately reducing line of sight. I am terrified the headlights are going to just quit altogether. The car also “shimmys” in time with the flickering lights. It appears to get worse when accelerating as well. Also it has been over 2 years since the headlight recall for this model. The dealership keeps saying, we don’t have the parts or just ignoring my requests altogether.

Filed with NHTSA, December 2023

Electrical
Failure of the starter motor, should be able to get the faulty part from mechanic. This rendered me unable to start my car and required a tow, thankfully not from the side of the highway. Confirmed faulty with tow driver and mechanic. The part has only been inspected by mechanic who mentioned this was the third starter motor failure he has seen on Subaru Imprezas. No warnings, though the car struggled to turn over earlier in the day.

Filed with NHTSA, June 2023

Engine
Knocking sound in engine confirmed by dealership service center to be a spark knock in the engine. No fix available and the service center stated "is a common problem in Impreza."

Where the 2018 fits in the Impreza's history

Redesigns and mid-cycle updates change what can go wrong.

The 2018 is the second model year of the Impreza's fifth generation (2017–2023).

Subaru updated the Impreza for 2020, so a 2018 does not have those changes.

What changed for 2020 (not on a 2018)
