Parts for your 2019 Subaru Impreza-Starter motor

2019 Subaru Impreza starter motor

Yes — the 2019 Subaru Impreza uses a conventional 12‑volt starter motor. This is confirmed by Subaru’s Factory Service Manual for the 2019MY Impreza (FB20 engine, Starter System section), the Subaru genuine parts catalogue listing a starter assembly for this model, and references to starter circuits and fuses in the 2019 Owner’s Manual. So the starter motor is very much relevant to servicing and repair on this vehicle.

The starter motor’s job is simple but critical: it spins the FB20 engine fast enough for fuel and spark to take over. A solenoid shoves the pinion gear into the flywheel ring gear, the motor cranks the engine, and once it fires, the pinion disengages. If the starter doesn’t do its thing, there’s no getting under way — no matter how new the fuel or plugs are.

There isn’t a set replacement interval for a starter on the 2019 Impreza, but a bit of preventative attention goes a long way. During regular servicing, it’s smart to check:

• Battery health and charging voltage — a weak battery can mimic a bad starter.
• Main power and earth/ground cables for corrosion or looseness, especially at the starter and body/gearbox earthing points.
• Starter relay and related fuses if there’s a click but no crank.
• Voltage drop across the positive and ground circuits while cranking, high drop points to cable or connection issues.

Common warning signs include slow cranking when the battery tests fine, a single loud click from the engine bay, intermittent no‑crank after a hot soak, or grinding noises that suggest the pinion or ring gear is unhappy. If these show up, a proper current draw test and bench test can confirm whether the starter is on the way out.

When replacement is needed, the routine is straightforward for a trained tech: disconnect the negative battery terminal, access the starter at the bellhousing, remove the electrical connectors and mounting bolts, swap the unit, and torque everything to spec. It’s good practice to clean the mating surfaces, refresh any tired cables, and verify the engine cranks cleanly with no abnormal noises. Genuine or high‑quality aftermarket units that match the FB20 spec will save headaches later. While they’re there, the workshop should also scan for any body/immobiliser faults if push‑button start models present no‑crank symptoms.

As part of scheduled servicing, asking the shop to check crank speed, cable condition, and charging performance around the 60,000–100,000 km mark is a low‑cost way to catch issues early and keep the Impreza starting first turn, every time.

What are the signs of a failing starter motor on a 2019 Subaru Impreza?

Slow cranking with a healthy battery, a single click and no crank, intermittent no‑start after the engine is hot, or grinding on engagement are the usual clues. A proper voltage drop and current draw test will separate starter faults from battery, cable, or relay issues.

Can a bad starter be mistaken for a flat battery?

Absolutely. Both can produce a slow or no‑crank situation. If the battery tests at good state‑of‑charge and the headlights don’t dim much during a start attempt, the starter or its cables may be the culprit. Testing under load is the quickest way to tell.

How much does a starter replacement cost in Australia or New Zealand?

Prices vary with parts choice and labour rates, but as a ballpark, expect roughly 1.0–1.5 hours labour plus the cost of a quality starter motor. Genuine units tend to cost more than reputable aftermarket options, a shop can quote precisely after testing.
