What happens if my Subaru Ascent spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Subaru’s recommendations.

What does a puddle underneath my Subaru Ascent mean?

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

Are hard starts and stops bad for my Subaru Ascent engine?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

Tune Into Your Subaru Ascent

Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, particularly if you want to keep your 2021 Subaru Ascent in tip-top shape. Periodic tune-ups can bring more power back to your Ascent’s engine. They're designed to help your engine start easier and run more efficiently, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Subaru's recommendations, you can rest assured you’re investing in your Ascent’s long-term engine performance.

Routine Engine Tune-Up Service for Your Subaru Ascent

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2021 Subaru Ascent. One option is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. The second service focuses on your Ascent's filters, specifically replacing the air filter and fuel filter. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your Ascent's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your Ascent's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where Should I Go for My Subaru Ascent Tune-Up?

If you’re looking for 2021 Ascent engine tune-up services, head to Firestone Complete Auto Care. Follow Subaru's recommended maintenance schedule or book an appointment as soon as you notice one of the following: shaking while the engine is idling, poor fuel economy, knocking noises in the engine, or a lit up check engine light on your dashboard.
