When should Infiniti QX50 spark plugs be replaced?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What does a puddle underneath my Infiniti QX50 mean?

Don't ignore puddles of fluid under your Infiniti QX50. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.

Are hard starts and stops bad for my Infiniti QX50 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.

Enhance Infiniti QX50 Performance with a Tune-Up

Is it tune-up time? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, especially if you want your 2021 Infiniti QX50’s engine to last for a long time. Periodic tune-ups can bring more power back to your QX50’s engine. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Infiniti, you’re taking vital steps toward keeping your QX50’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Infiniti QX50

The Firestone Complete Auto Care location in your community offers several Infiniti QX50 engine tune-up services. The first 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*. A second service option replaces the air and fuel filter in your QX50. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your QX50. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your QX50's mileage and maintenance history can uniquely impact its tune-up needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where to Get a Tune-Up for Your Infiniti QX50

If you’re looking for 2021 QX50 engine tune-up services, head to Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Infiniti, or make a service appointment if you notice any of these symptoms from your engine: decreased gas mileage, "rough" idling or stalling when stopped, knocking noises in the engine, or a lit up check engine light on your dashboard.
