Still have questions? We’ve got answers.

We've put together the most important information on tires, vehicle maintenance, repairs, warranties, and more to help you drive with confidence.

How does the extreme heat in McKinney affect my vehicle's belt and hose health?

Heat in McKinney makes engine belts and hoses brittle, which can lead to sudden leaks or failures. We provide the thorough inspections and tire care needed to keep your vehicle efficient. Our shop is ready to handle the maintenance that protects your car from the heat.

How often should I service my vehicle?

You should service your vehicle every 5,000 to 7,500 miles or every 6 months, whichever comes first, for routine maintenance like oil changes and inspections. Always check your owner’s manual, as some vehicles and driving conditions may require more frequent attention to keep everything running smoothly and safely.

How do I know what services to perform on my vehicle and when?

Any of our friendly, neighborhood locations can help you determine the schedule that’s best for your car. In many cases, the maintenance schedule is determined by the manufacturer for optimal service life for your vehicle; this can be found in the owner’s manual.

Do I need an appointment, or can I walk in?

Appointments are recommended, but walk-ins are always welcome.

Will I get an estimate before work begins?

Absolutely. We provide clear estimates and only complete the work you approve.

Why is my check engine light on?

It could be something simple or serious. We recommend a diagnostic scan to find the cause.

How do I know when my next oil change is due?

After each oil change at Sun Auto Tire & Service, our technician will place a reminder sticker in the upper left-hand corner of your windshield. For added convenience, we can also send you a service reminder when it’s time for your next appointment. To enroll in this program, ask your Service Advisor for details.”

Is my warranty voided if I get non-dealer work done?

No. In fact, it is against the law for a manufacturer to dishonor their warranty just because the vehicle was serviced elsewhere. As long as the service is performed by capable car mechanics like the ones at your friendly neighborhood Sun Auto Tire & Service, your warranty is valid.

Can I get an Express Lane oil change without an appointment?

Appointments aren’t necessary at an Express Lane location – get in and out and back on the road in about 20 minutes.
