2021 Subaru WRX STI Maintenance Schedule

What is the recommended maintenance schedule for the 2021 Subaru WRX STI?

What to Know About 2021 Subaru WRX STI Scheduled Maintenance

Take care of your Subaru WRX STI and it'll take care of you. With the right maintenance at the right time, your WRX STI has a good chance of hitting 200,000 miles or more. But how do you know what service to get and when? Instead of waiting for an issue to arise with your WRX STI, you can stay ahead of problems before they even begin. It’s as easy as following the recommended maintenance schedule that’s been written specifically for your 2021 Subaru WRX STI!

This recommended maintenance schedule is written by the auto manufacturer, Subaru themselves. Driving conditions, climate variations, and other variables can affect which scheduled maintenance services you’ll need; however, recommended maintenance usually includes services like oil changes, tire rotations, brake pad replacement, filter changes, and fluid checks and exchanges. Keeping up with routine service appointments is a great way to keep your WRX STI running for longer, increase your vehicle safety, and prevent common 2021 Subaru WRX STI problems.

Learn About Vital Maintenance Needs for Your Subaru WRX STI

Bring your 2021 Subaru WRX STI to Firestone Complete Auto Care for factory-recommended maintenance services and our technicians will jump right in with a Courtesy Check. This Courtesy Check can establish a baseline of what may need to be addressed during your service appointment. Every Courtesy Check will include a visual inspection of your WRX STI. We’ll check your head and tail lights, fluid levels, filters, tires (and their alignment!), and windshield wiper blades. We’ll also perform a free battery check to determine your battery’s charge level.

Think you could be due for a new battery in your 2021 Subaru WRX STI? In general, car batteries only last three to five years. There’s a chance you’ll need a replacement sooner, but it depends on the climate in your area as well as your driving habits. Short trips and extreme temperatures can shorten the overall life expectancy of your Subaru WRX STI battery. Sure, you could wait until your battery is completely dead, but it’s a much wiser decision to replace it before you need to. Otherwise, you may find yourself (and your trusty WRX STI) stuck in the middle of nowhere. Your Subaru WRX STI won’t even be able to start with a weak battery, much less get you where you need to go.

Staying on schedule for battery replacements and motor oil changes can support your engine’s overall performance and keep your 2021 Subaru WRX STI running newer, longer. To learn how often Subaru recommends you have the oil changed in your 2021 WRX STI, check out the information table at the beginning of this page. Keep in mind that your oil change interval could be different given your driving style and climate. A Firestone Complete Auto Care technician will be happy to help you determine the best oil change frequency for your car’s needs. Not sure what type of oil to use for your 2021 Subaru WRX STI? We can help with that, too!

Routine upkeep for your Subaru WRX STI suspension and steering system can improve ride comfort and help you maintain control of your vehicle. Don’t let a misalignment or pulling steering wheel put you in danger. Trust our technicians to inspect system components and if needed, perform Subaru WRX STI suspension and steering services. These might include wheel alignment, power steering fluid flushes and replenishments, ball joint lubrication, wheel bearing replacement, and strut replacement. Prevent damage or premature wear and tear on your Subaru WRX STI's steering system with regular maintenance.

If you skip recommended Subaru WRX STI services, you might find yourself with a hot mess on your hands – quite literally. A damaged A/C system is never fun, and an overheated engine can cause significant issues (like a total car breakdown!). We can help you with all those issues. Our technicians have the knowledge and tools to repair and maintain the heating and cooling systems for your Subaru WRX STI’s engine, and we can service your A/C system, too. Is your Subaru WRX STI radiator in need of replacement? We got it. Is your A/C blowing hot air? We’re here to fix that, too. Firestone Complete Auto Care is your one-stop shop for 2021 Subaru WRX STI maintenance and repairs.

Don’t wait until something goes wrong with your car. Visit your nearest location for proactive maintenance today.

2021 Subaru WRX STI Maintenance Q&A

Take an active role in maintaining your 2021 Subaru WRX STI. Get answers to common Subaru WRX STI maintenance questions and learn more about caring for your vehicle.

  • What do I do if I hit a pothole in my Subaru WRX STI? Check your car for pothole damage! If you’ve recently hit a pothole (or even if you don’t remember hitting one… they can be sneaky!) check your tire treads, tire sidewalls, and wheels for damage. Potholes can also knock your car out of alignment, so have your alignment checked if you suspect you’ve driven over a rough patch of road lately.
  • When should I use high mileage oil in my Subaru WRX STI? Do you have more than 75,000 miles on your Subaru WRX STI? If so, request to switch to high mileage oil at your next oil change. This type of oil is specially formulated to keep aging engine parts in the best possible condition.
  • Can I ignore dashboard lights on my Subaru? It's better to get them addressed as soon as possible. An illuminated dashboard light means something in your vehicle isn't functioning like it should. Letting problems linger can mean bad news for your Subaru WRX STI, so be sure to take your car in for service as soon as you notice an illuminated dashboard light
