Parts for your 2020 Mitsubishi Asx-Starter motor

2020 Mitsubishi ASX starter motor: what it does, how long it lasts, and when to sort it

Technical sources confirm the 2020 Mitsubishi ASX is fitted with a conventional 12‑volt starter motor. Mitsubishi Motors service literature for the ASX/Outlander Sport platform lists a starter assembly for the 2.0‑litre MIVEC petrol, and mainstream parts catalogues from OEM and aftermarket suppliers also carry direct-fit starter units for 2020 models. As a non-hybrid, the ASX relies on a dedicated starter to crank the engine.

The starter motor’s job is simple but critical: spin the crankshaft fast enough for the 2.0‑litre petrol to fire on its own. It engages the ring gear on the flywheel via a small pinion, then disengages the moment the engine catches. On some markets, certain ASX variants may have idle stop–start, those use a beefed-up starter and an AGM/EFB battery, but it’s still a starter-driven system.

There’s no scheduled replacement interval for a starter on the ASX, but smart servicing keeps it happy. The basics matter: a strong battery, clean terminals, solid engine and chassis earths, and tidy wiring. During regular servicing, a tech will typically check cranking voltage, inspect the main starter cable and ground strap for corrosion, and listen for tell-tale noises.

• Common symptoms: slow or laboured cranking, a single loud click (solenoid), rapid chattering (low voltage), or grinding after start (worn pinion or ring gear).
• Quick checks before blaming the starter: test the battery, inspect terminals, verify the starter relay, and confirm the inhibitor/clutch switch and immobiliser are behaving.

If replacement is needed, the starter on the 2020 ASX is mounted to the transaxle bellhousing where it meets the engine. Access typically requires getting under the bonnet and often underneath the car. Best practice is to disconnect the negative battery terminal, protect stored settings if needed, and avoid arcing the main starter cable. Refit using correct hardware and heat shields, route the loom as per factory, and torque to spec as per service info.

Owners are well served choosing a quality new or reputable remanufactured unit. If the vehicle has stop–start, the replacement must be rated for that duty cycle, and the battery should match (AGM/EFB). Many starters last well beyond 150,000 km, but heat, oil contamination, weak batteries, and constant short trips can shorten their life. A quick health check every service can save a surprise no‑start on a cold Monday.

Popular questions about 2020 Mitsubishi ASX starter motors

Does the 2020 Mitsubishi ASX definitely have a starter motor?

Yes. Factory service information and mainstream parts catalogues list a dedicated starter for the 2.0‑litre petrol ASX. It’s a conventional 12‑volt unit, some variants designed for idle stop–start use a heavier‑duty version.

Where is the starter motor on a 2020 ASX?

It’s bolted to the transaxle bellhousing where the gearbox meets the engine. Access is usually from above and below, exact reach points can vary slightly by market spec, but it’s typically low down near the engine–gearbox join.

What causes a no‑crank on an ASX besides the starter?

Most no‑crank issues are battery or connection related. Also check the starter relay, engine/chassis grounds, the transmission range (inhibitor) switch on autos or clutch switch on manuals, and immobiliser/key faults before condemning the starter.
