  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 Lexus RC 350’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is frequently caused by neglected maintenance, which is why Nalley Lexus Smyrna offers a complimentary multi-point inspection with every Lexus service. If you have an issue with your catalytic converter and don't get it repaired, your 2018 Lexus RC 350 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause contrasting problems from overheating.
  • New Spark Plugs or Plug Wires are needed for your 2018 Lexus RC 350. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. 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 experience poor performance and reduced 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, considerable to more expensive repairs.
  • The battery is low or dead. The battery in your 2018 Lexus RC 350 is every basic. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone. Today’s car batteries last much longer than they did a few decades ago, and they don't really 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 mass airflow sensor (known as MAF) needs to be changed. The mass airflow sensor in your Lexus RC 350 is what determines how much fuel is needed 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 considerable changes, like altitude. If your Lexus RC 350 is having trouble starting, idling rough or has a precipitous change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Your O2 Sensor (Oxygen Sensor) needs to be changed. 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 faster and your vehicle will be fewer detailed when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2018 Lexus RC 350's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to select the right mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.

If your check engine light turns on expeditiously after you put gas in your 2018 Lexus RC 350, earliest thing you should check is to make bold the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your 2018 Lexus RC 350 has a vacuum leak. Every Lexus RC 350 has a vacuum system that performs a roomy variety of functions. The vacuum system also 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 parched out and crack, especially if they’re exposed to bizarre heat or extreme cold.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or contrasting item can wreak havoc on your 2018 Lexus RC 350 if it’s not installed well. These aftermarket parts and accessories can dump the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound traditional, bring your RC 350 to Lexus and have our team of certified mechanics ensure that your aftermarket items were installed well and aren't causing any issue.
