• New Spark Plugs or Plug Wires are required for your 2023 Lexus LS 500h. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your car. This explosion is what moves the pistons and makes the engine run smooth. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or old, you will go through a evident poor performance and decreased power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, leading to more costly repairs.
• Your 2023 Lexus LS 500h has a vacuum leak. Each Lexus LS 500h has a vacuum system that performs a wide variety of functions. The vacuum system again helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, particularly if they're exposed to intense heat or extreme cold.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2023 Lexus LS 500h if it's not installed accurately. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even limit the car from starting. If these issues sound familiar, bring your LS 500h to Lexus and have our team of accomplished certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or using OEM components first place might cost a little bit more but could assist you save considerably from having to get poor work and damage caused by poor installation work corrected.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lexus LS 500h is what determines how much fuel is required to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your Lexus LS 500h is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a critical sign of a broken mass airflow sensor.
• The battery is low or dead. The battery in your 2023 Lexus LS 500h is each important. Without a vehicle battery, your vehicle won't start, light up the road in front, play the radio or charge your phone. Today's vehicle batteries last much longer than they did a few decades ago, and they don't absolutely require maintenance. The price of a new one depends on the type of Lexus you drive, but check our current service coupons and specials.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2023 Lexus LS 500h's exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A broken catalytic converter is usually caused by repeatedly neglected maintenance, which is why Stevinson Lexus of Lakewood offers a complimentary multi-point examination with each Lexus service. If you have an issue with your catalytic converter and don't get it repaired, your 2023 Lexus LS 500h will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other delicate problems from overheating.
• One of the most typical and frequent cause is that your 2023 Lexus LS 500h gas cap is loose, broken or missing. The gas cap for your 2023 Lexus LS 500h serves multiple purposes. It prevents unpredictable gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What hits if you have a broken fuel cap? If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump and be more expensive. Luckily, to replace a gas cap isn't costly. If your check engine light turns on expeditiously after you put gas in your 2023 Lexus LS 500h, first thing you should check is to make sure the cap isn't loose — or that it's still on your car's roof or at the fuel pump.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns more expeditiously and your car will be less efficient when it comes to fuel economy. So what hits if I don't replace your O2 sensor? A broken sensor can not only affect your miles per gallon, but it can cause serious damage to your catalytic converter and your 2023 Lexus LS 500h's spark plugs. The O2 sensor sends data to the vehicle's onboard computer to determine the specifically appropriate mixture of air and fuel that enters the cylinders in your engine. A broken O2 sensor can again cause a vehicle to fail an emissions test.
