- How many miles before my Lexus needs an oil change?
- Part of the Lexus of Knoxville ownership experience is letting us worry about your maintenance schedule so you don’t have to. Someone from our service center will contact you when it is time to get your scheduled maintenance, including an oil change. However, you can check your owner’s manual to determine the time intervals for service for your specific vehicle if you wish to manage this as well. If you are unable to find your owner’s manual, give us a call and we will be happy to look it up for you.
- When should I replace my car battery?
- You should check the warranty date on the battery to determine when it should be replaced. The letter is the month – A for January, B for February and so on. The number is the year. A battery that shows D18 means April 2018. You should change the battery just before this date so you do not end up stranded with a dead battery. You can also bring your battery into our service center to have it checked.
- What if my vehicle doesn’t start?
- There are several things that could result in a vehicle not starting such as a dead battery, a bad starter, a bad alternator, a bad sensor, or even a broken timing belt.
- If the issue is a starter or the battery, you will generally hear a click when you engage the ignition. If you have a voltmeter, you should check the battery. It should have at least 12 volts when the vehicle is off. Have someone turn the key while you check the voltmeter and the voltage does not drop below 10.50 volts, the problem is most likely the starter, assuming that all other systems are working fine.
- What if my “Service Engine Soon” light turns on?
- You should bring your vehicle in as soon as your service engine soon or check engine light comes on. The only way to determine the issue with your vehicle is by plugging in the code reader into the diagnostic port.
- How often do I need to buy or replace tires?
- There is no hard and fast rule for replacing tires because it depends on the type of tires, how you drive, how often, and where. Tires will wear faster if you are driving often on rough surfaces, such as gravel. Tires made with soft rubber also tend to wear faster. Every tire has an expected number of miles it will last. However, you should still always check your tires for low pressure, wear, or other imperfection. If you notice that the tread is almost even with the wear bars, then you need to get new tires.
- Do I need to align my tires when I get new ones?
- It is always a good idea to have your alignment checked. If you notice and uneven wear pattern on your vehicle, then you should absolutely have an alignment done.
- What kind of tires should I get?
- When you are ready to get new tires, you should let your service technician at Lexus of Knoxville know where you drive, how often, and if you drive mostly in the city or on the highway. With this information, they will be better able to help you find the best tire for you and your vehicle.
- When should I replace my belts and hoses?
- The time frame varies based on the product. When hoses start to get soft or if they are showing cracks, they should be replaced. When belts show dry rotting, the bottom side is shiny or if the tensioner can no longer keep tension on the belt, it’s time to change the belts.
- What is the difference between OEM and generic parts?
- OEM parts are “original equipment manufacturer” parts. That means that they are made by the manufacturer, like Lexus. They may be sold by Lexus or a third party. generic parts are made by another manufacturer to fix your Lexus vehicle. Even though they fit, they do not have the same quality as OEM parts. Here at Lexus of Knoxville, we only use Lexus OEM parts.
- Why should I use ASE-certified technicians?
- No one knows your Lexus better than the technicians at Lexus of Knoxville. That’s because our personnel are Lexus trained and certified—so they’ll fix your car according to the exact manufacturer standards. It is also important to note that in order to properly service a Lexus vehicle, technicians need to be certified to use the specific diagnostic equipment. Without these tools or knowing how to use them, technicians cannot properly identify a problem with your vehicle. This can easily lead to an inaccurate diagnosis that will end up costing you more than you need to pay. That is something that will never happen here at Lexus of Knoxville. By using an ASE auto repair technician, like those at our service center, you know that your repairs will be done correctly the first time.
- What’s wrong with uncertified mechanics?
- If you choose a mechanic that does not have the proper Lexus certification, you cannot know whether or not that mechanic knows how to do the job. You also cannot guarantee that they will use quality OEM parts. Additionally, they may not guarantee the parts or their work.
