When should Infiniti QX56 spark plugs be replaced?

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 Infiniti’s recommendations.

What should I do if I see leaks under my QX56?

Don't ignore puddles of fluid under your Infiniti QX56. 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.

What do hard starts and stops do to my QX56 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.

Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Enhance Infiniti QX56 Performance with a Tune-Up

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, particularly if you want to keep your 2011 Infiniti QX56 in tip-top shape. Routine engine tune-ups can bring power back to your QX56. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions. When you take your car for regular engine tune-ups as recommended by Infiniti, you can rest assured you’re investing in your QX56’s long-term engine performance.

Engine Tune-Up for Infiniti QX56

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2011 Infiniti QX56. The first is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. Another service option pays special attention to the filters in your QX56. Specifically, we replace the fuel filter and air 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 QX56's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your QX56'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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where Should I Go for My Infiniti QX56 Tune-Up?

Come to Firestone Complete Auto Care for your next 2011 QX56 engine tune-up. Consult your vehicle’s recommended service schedule from Infiniti, or make a service appointment if you notice any of these symptoms from your engine: stalling or shaky idling when you’re stopped, diminished fuel economy, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
