Subaru Starter Replacement Cost
Replacement of the electric starter motor and solenoid assembly to ensure reliable engine cranking.
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
- Disconnect battery ground and high-amperage power lead to the starter.
- Remove air intake ducting or intercooler (on XT/WRX models) to gain clearance.
- Unbolt the transmission-to-engine mounting bolts that secure the starter motor.
- Extract the old unit and inspect the flywheel/flexplate teeth for damage.
- 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.
