Subaru Maintenance: Understanding the A, B, C, and D Maintenance Plans in Canada

Owning a Subaru means choosing reliability, performance, and safety.
But to maintain these qualities, regular maintenance is essential.

In Canada, the Subaru maintenance plan is designed to maximize the lifespan of each model—whether it's a Subaru Forester, Outback, Impreza, Crosstrek, or WRX.

This program follows a clear schedule alternating between four types of maintenance: A, B, C, and D, performed based on mileage or elapsed time.

Subaru recommends maintenance every six months or 10,000 km, whichever comes first.

What are Subaru A, B, C, and D Maintenance?

Subaru A Maintenance

A maintenance is the most frequent and simplest, perfect for keeping your Subaru ready for Quebec's trails.

Engine oil change and filter replacement;
Battery maintenance;
Lubrication of latches, hinges, and locks;
