Courtesy Checks on Your Lexus IS250

Every service performed at Firestone Complete Auto Care includes a multi-point Courtesy Check. Why? So we can fully assess what your Lexus IS250 may need and get ahead of potential problems. What will be inspected during a Courtesy Check? First, a technician will pop the hood on your Lexus IS250 and test the battery to find out how much charge is remaining on it. We know that the best time to replace your battery is before you need to. The check will continue with a visual inspection of your Lexus IS250's filters, lights, wiper blades, hoses, alignment, tires, fluid levels, and belts. After the Courtesy Check, we’ll give you a detailed report of what we found. Courtesy Checks cost nothing but a few minutes of your time. Time spent caring for your car is time well spent, indeed!

Complete Vehicle Inspection Services for Your Lexus IS250

We perform a Courtesy Check any time you bring your car to a local Firestone Complete Auto Care for service, but we can also dig deeper and perform a Complete Vehicle Inspection on your 2011 Lexus IS250 if you prefer. A Complete Vehicle Inspection can help diagnose bothersome changes in how your car runs or handles. In addition to a visual check of everything that's included in a Courtesy Check, a Complete Vehicle Inspection also includes an examination (by hand!) of your steering and suspension system, brakes, and exhaust components. With this inspection, we want to help you stay on top of any issues that may need immediate attention in order to prevent further damage. Because you can only drive with confidence when you have confidence in the health and integrity of your Lexus IS250.

State Inspection Testing for Your Lexus IS250

Depending on your location, you may be able to take care of your state inspection or safety test at your local Firestone Complete Auto Care. These inspections are governed by state automotive laws and may vary in different locations. Call your store ahead of time to confirm that this service is offered.

Common 2011 Lexus IS250 Vehicle Inspection Questions

  • How much does it cost to get a Complete Vehicle Inspection on a Lexus IS250? We routinely offer coupons and discounts for this important service. Call your local Firestone Complete Auto Care for a free estimate for your 2011 Lexus IS250.
  • How do I know if my Lexus IS250 needs a check-up? It needs a check-up if something feels 'off' to you, the driver. Your Lexus IS250 could benefit from a Courtesy Check if it has any illuminated dashboard lights, you hear weird noises coming from any part, the engine doesn't start sometimes, or your vehicle pulls to one side.
  • Can you fix my 2011 Lexus IS250 so it will pass a state inspection test? Don’t panic! Come in for a complete inspection today and we’ll find (and repair) the root cause before you have your vehicle retested.
  • When should I get a complete vehicle inspection for my Lexus IS250? The best time to get a complete vehicle inspection for your Lexus IS250 is before going on a road trip for the peace of mind. Another great time is when something abnormal occurs, and you can't pinpoint the issue. You might notice new dashboard lights, hear strange noises from under the hood, or your steering wheel doesn't feel like it once did.
  • Where can I find coupons for Lexus IS250 inspections? We’re always looking for ways to help our customers save, which is why we frequently update our offers. Check out our latest offers to see how you can save today, and download our mobile app to stay in the loop and receive special deals.
  • Sometimes I can’t get my Lexus IS250 engine to start. Will an inspection help? While an inspection won't immediately fix your Lexus IS250 engine, it can help us identify the underlying issue so we can get the engine back up and running. If you're experiencing unusual performance, it's likely time for an inspection or diagnostic service.
