Parts for your 2013 Subaru Impreza-Starter motor

2013 Subaru Impreza starter motor — what it does, care, and when to replace

Yes, the 2013 Subaru Impreza is fitted with an electric starter motor. This is confirmed in the Subaru Factory Service Manual for 2012–2014 Impreza (Starting/Charging System), the Subaru Genuine Parts catalogue (which lists a starter motor assembly for FB-series engines), and common OE supplier data from Denso’s application guides. Even in markets where some trims feature Auto Start Stop, the system still relies on a heavy‑duty starter motor designed for more frequent cranking.

The starter’s job is simple but critical: it draws high current from the battery, engages the flywheel ring gear with a small pinion via a solenoid, and spins the FB20 engine quickly enough for the ECU to take over fuel and spark. Once the engine fires, the starter disengages. Without it, there’s no crank, no go.

• Common signs of starter trouble:
  • Single click, slow crank, or no crank with dash lights still bright
  • Intermittent starting that improves after tapping the housing (worn brushes/solenoid contacts)
  • Grinding noise at start (pinion or ring gear engagement issues)

There’s no fixed replacement interval, starters are serviced on condition. Good preventative care on a 2013 Impreza is mostly about the support act: healthy battery, clean terminals, solid earth straps, and sound wiring to the starter and starter relay. If the engine cranks slowly, a proper voltage‑drop test across the positive cable, negative cable, and the starter itself can save a lot of guesswork.

• Helpful tips:
  • Keep the battery at full charge, weak batteries cook starters
  • Clean and tighten the main earth from battery to body/engine
  • Listen for changes in cranking speed after long, hot drives (heat‑soak can reveal marginal units)
  • If equipped with Auto Start Stop, use the correct spec battery (often AGM) to protect the starter

When replacement time comes, go for a genuine Subaru unit or an OE‑equivalent (commonly Denso) remanufactured starter. Disconnect the negative battery terminal before touching anything. The starter is mounted at the bellhousing, access varies slightly between manual and CVT. Inspect the flywheel ring gear while you’re there, renew any tired cables or the starter relay, and refit heat shields and loom clips exactly as found. After installation, check for clean, crisp engagement and consistent cranking speed. With decent battery care and clean connections, most starters will rack up plenty of kilometres without drama.

Does the 2013 Impreza have Auto Start Stop, and does it change the starter?

Some markets and trims offered Auto Start Stop around this era. Those cars still use a starter motor, but it’s engineered for higher cycling and paired with the correct battery spec (often AGM). Using the right battery and keeping it well charged helps preserve starter life.

What are the most common symptoms of a failing starter on a 2013 Impreza?

A loud click with no crank, slow cranking even with a good battery, or grinding at engagement are the big ones. If everything goes dead when turning the key, think battery or main connections first, if lights stay bright but it won’t crank, the starter or its control circuit is more likely.

How long should a starter last on this model?

Many last 150,000–250,000 km, depending on driving and battery care. Lots of short trips or Auto Start Stop use can shorten lifespan, while a strong battery and clean grounds can extend it significantly.
