2019 Lexus GS300 Courtesy Inspection

When you bring your vehicle to Firestone Complete Auto Care for any service, we’ll automatically do a multi-point Courtesy Check. We do this to get a clear idea of your Lexus GS300’s maintenance needs and get ahead of potential problems. What will be inspected during a Courtesy Check? The technician will begin by testing your Lexus GS300's battery to see how much charge it has left – and determine if it may fail in the near future. No one wants to be stranded with a dead or weak battery! After we’ve inspected your Lexus GS300’s battery, we’ll visually inspect your filters, lights, wiper blades, alignment, tires, hoses, belts and fluid levels. Once your Courtesy Check is complete, we’ll outline everything we found in a report for you. Courtesy Checks cost nothing but a few minutes of your time. If those few minutes can save you from repair costs down the road, they’re worth it!

Complete Vehicle Inspection for 2019 Lexus GS300

While every visit to your local Firestone Complete Auto Care includes a Courtesy Check, we can also dig deeper and perform a Complete Vehicle Inspection on your 2019 Lexus GS300 if you prefer. The Complete Vehicle Inspection service can help find the root of any new issues in your vehicle. A Complete Vehicle Inspection includes everything in a Courtesy Check, plus a hands-on examination of your exhaust system, steering and suspension, and brakes. This inspection is aimed at informing you of any major problems that could wreak havoc on your car if left unaddressed. We’re here to help you take care of your Lexus GS300 and keep it running newer, longer.

These inspections are governed by state automotive laws and may vary in different locations. If you need this type of inspection, call your store to be sure it’s offered before you take your vehicle in for service.
