Parts for your 2020 Subaru Impreza-Starter motor

2020 Subaru Impreza starter motor

Yes, the 2020 Subaru Impreza is fitted with a conventional 12‑volt starter motor. This isn’t guesswork: Subaru’s own technical material confirms it. The 2020 Impreza Owner’s Manual (Starting and operating – Starting the engine) describes operating the starter when the ignition switch or push‑button is engaged, including clutch/neutral interlocks. The Subaru Service Manual for the GK/GT Impreza (Starting/Charging – Starter section) details removal, installation and inspection of the starter assembly. Subaru’s genuine parts catalog also lists a dedicated “Starter assembly” for the 2.0‑litre FB‑series engine used in this model year. All up, the starter motor is absolutely relevant to this vehicle.

On the Impreza, the starter motor’s job is to crank the FB20 engine by engaging the flywheel ring gear via its solenoid drive, getting the engine to fire so the ECU and fuel system can take over. Even cars with push‑button start still use this electric starter, the button just replaces the key turn. Many 2020 models also feature auto stop‑start, so the starter is built to handle more frequent restarts and relies on a healthy battery and good connections to do it reliably.

For servicing, there’s no fixed replacement interval, but a bit of routine attention goes a long way. Keep the battery in top nick, clean and tighten the terminals, and don’t forget the engine earth straps. If cranking gets slow, you hear a single click, or there’s an intermittent no‑crank under the bonnet, have a tech load‑test the battery first, then check starter current draw and voltage drop across the main cables. Oil contamination from a weeping rocker cover or bellhousing area can also shorten starter life, so fix leaks promptly.

When replacement is needed, choose a quality OE or reputable reman unit suited to stop‑start duty. The job involves disconnecting the negative terminal, safely raising the car, removing the intake ducting or airbox for access, then undoing the main battery cable and signal wire from the solenoid and the mounting bolts. Refit with correct torque, route the cables so they’re not rubbing, and perform any battery management/idle relearn procedures recommended in Subaru service information. A fresh starter should crank smartly, with no grinding or unusual noise. Treated well, most starters will see well over 150,000 kilometres in Aussie and Kiwi conditions.

Popular questions about 2020 Subaru Impreza starter motors

Does the 2020 Impreza with push‑button start still have a starter motor?
Yes. Push‑button start just changes how the driver requests a start, the car still uses a 12‑volt starter motor and solenoid to crank the engine. The body control and engine computers handle the relays and safety interlocks automatically.

What are common signs the starter is on the way out?
Sluggish cranking even with a good battery, a single loud click with no spin, intermittent no‑crank when hot, or a grinding/whirring noise as the pinion disengages are typical clues. Always rule out a weak battery and corroded terminals first, as they’re more common than a failed starter.

How much does starter replacement typically cost?
Costs vary by region and parts choice, but expect a quality unit plus fitting to land in the mid to high hundreds of dollars in Australia or New Zealand. Stop‑start rated units may cost a touch more. Having the battery and cables checked at the same time is smart money.
