    Why this fails

    Internal brush wear or solenoid contact pitting typically occurs after 100k+ miles, particularly on FB20/FB25 engines with Auto Start-Stop systems which cycle the starter significantly more often. High heat from the adjacent exhaust/manifold can also degrade the internal windings over time.

    What the job involves

    1. Disconnect battery ground and high-amperage power lead to the starter.
    2. Remove air intake ducting or intercooler (on XT/WRX models) to gain clearance.
    3. Unbolt the transmission-to-engine mounting bolts that secure the starter motor.
    4. Extract the old unit and inspect the flywheel/flexplate teeth for damage.
    5. Install new starter, torque bolts to 37 ft-lbs (avg spec), and perform a voltage drop test.

    If you delay this repair

    Total vehicle strandage. Unlike a weakening battery, a starter failing via 'flat spots' or internal shorts can leave you suddenly immobile in a parking lot or at a gas station with no warning.

    Save money

    • Look for Subaru Remanufactured units (marked with an 'R1' suffix) which carry the same warranty as new but are $150-$200 cheaper.
    • Clean battery terminals first—many 'bad starters' are actually just high-resistance connections or corroded grounds.
    • Independent shops can often source high-quality Denso (the original manufacturer) units for significantly less than a dealer-branded box.
