What happens if my Hyundai Sonata 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 Hyundai’s recommendations.

What do I do if I see a pool of liquid under my Hyundai Sonata?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are some driving habits better for my Hyundai Sonata engine than others?

Hard starts and stops put extra wear and tear on engine components. Smooth, gradual starts and stops, on the other hand, are a great way to help your engine run better. They can also help maximize your fuel economy.

Enhance Hyundai Sonata Performance with a Tune-Up

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you drive a 1990 Hyundai Sonata. Periodic tune-ups can bring more power back to your Sonata’s engine. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Hyundai's recommendations, you can rest assured you’re investing in your Sonata’s long-term engine performance.

Hyundai Sonata Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Hyundai Sonata engine tune-up services. The standard Firestone Tune-Up is one service option. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. Another service option pays special attention to the filters in your Sonata. 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 Sonata's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your Sonata: your vehicle’s maintenance record and mileage can determine which service is best. If you’re not sure what services are the best fit for your car, let us help! Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
