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.
What are the long-term consequences of driving on salt-covered roads in St. Charles?
Salt-covered roads in St. Charles lead to deep rust on your vehicle’s frame and brake lines, causing compromised structural integrity. We provide the targeted undercarriage inspections and brake services needed to protect your car. Our shop ensures your vehicle stays road-ready with dependable service.
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 Plaza 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 Plaza Tire Service, your warranty is valid.
