Why Is My Check Engine Light On? Common Causes and How Musser Automotive Can Help

Seeing your check engine light suddenly appear on your dashboard can cause immediate concern. While this warning light doesn’t always indicate a catastrophic problem, it should never be ignored. The check engine light is part of your vehicle’s onboard diagnostic system (OBD), designed to alert you to potential issues that require attention. At Musser Automotive, located at 1343 Old Louisville Rd, Bowling Green, KY 42101, we specialize in advanced diagnostics to quickly identify and resolve the cause of your check engine light. Here are some of the most common reasons behind that warning.

Common Reasons for the Check Engine Light

Faulty Oxygen Sensor
The oxygen sensor monitors the amount of unburned oxygen in your car’s exhaust. When it malfunctions, it can negatively affect your car’s fuel efficiency and increase harmful emissions. If left unchecked, a faulty oxygen sensor can also cause damage to your catalytic converter. At Musser Automotive, we can quickly test and replace a faulty sensor to restore your vehicle’s performance.
Loose or Faulty Gas Cap
Believe it or not, one of the simplest causes of a check engine light is a loose or damaged gas cap. The gas cap seals the fuel system and helps maintain pressure within the fuel tank. If it's not properly sealed, it can cause fuel vapors to escape, which triggers the check engine light. Before you panic, check if your gas cap is tightened properly. If the light persists, our experts at Musser Automotive can determine if the gas cap is the problem or if something else is going on.
Catalytic Converter Issues
The catalytic converter is a critical component of your vehicle’s exhaust system. It helps reduce harmful emissions by converting toxic gases into less harmful substances. Over time, it can become clogged or fail due to neglect of other maintenance tasks, such as replacing a bad oxygen sensor. A malfunctioning catalytic converter can lead to poor fuel economy, reduced performance, and potential engine damage. Musser Automotive’s certified technicians can diagnose and replace catalytic converters using top-quality parts to restore your vehicle’s emission system.
Mass Airflow Sensor Failure
The mass airflow sensor monitors the amount of air entering your engine and adjusts the fuel injection for optimal performance. A malfunctioning sensor can lead to reduced fuel efficiency, engine stalling, and poor acceleration. If your mass airflow sensor is causing the check engine light, our team will provide a thorough diagnostic test to determine the best course of action.
Ignition Coil or Spark Plug Problems
Your vehicle's ignition system is crucial for starting the engine and ensuring it runs smoothly. Worn-out spark plugs or ignition coils can lead to misfires, rough idling, or even difficulty starting the engine. Ignoring these issues can cause further damage to your vehicle’s engine and exhaust system. Musser Automotive offers fast and efficient ignition system repairs to keep your engine running smoothly.

How to Maintain Your Brakes for Safety and Performance

March 21, 2025

Brakes are arguably the most crucial component of your vehicle when it comes to safety. Maintaining them properly is essential not only for the longevity of your car but also for the safety of you and your passengers. At Musser Automotive in Bowling Green, KY, we understand that keeping your brakes in top-notch condition can sometimes feel like a daunting task. However, with regular maintenance and proper care, you can ensure that your vehicle stops safely every time, no matter the conditions. In this guide, we’ll cover the key steps involved in brake maintenance, how to identify early signs of brake issues, and why regular brake checks are so important. Whether you’re a first-time car owner or a seasoned driver, this information will help you make informed decisions about your vehicle’s care. The Importance of Brake Maintenance Your brakes are responsible for stopping your vehicle in a timely and controlled manner, whether you're driving on highways, city streets, or in stop-and-go traffic. Over time, the wear and tear on your braking system can lead to decreased performance, affecting your safety on the road. Regular brake maintenance ensures that your vehicle performs optimally and reduces the risk of sudden brake failure. At Musser Automotive in Bowling Green, KY, we always remind our customers that brake maintenance isn’t just about fixing problems—it’s about preventing them from happening in the first place. Early detection of issues such as worn brake pads or low brake fluid can save you from costly repairs down the road and, more importantly, from dangerous driving conditions. Key Components of the Brake System Understanding how your brake system works is the first step in maintaining its performance. The brake system consists of several critical components: Brake Pads: The brake pads press against the brake rotor to create friction, which slows down your vehicle. Over time, the friction wears down the pads, reducing their effectiveness. Brake Rotors: Rotors are the large discs that the brake pads clamp onto when you press the brake pedal. If the rotors are warped or worn unevenly, they can cause vibrations or decreased braking power. Brake Fluid: Brake fluid is essential for transferring the force from your foot on the pedal to the brake mechanism itself. Low or old brake fluid can cause your brakes to feel spongy or unresponsive. Brake Lines: These carry brake fluid to the brakes. If any of these lines become cracked or damaged, brake fluid could leak, leading to poor brake performance. Calipers: Brake calipers are responsible for squeezing the brake pads onto the rotors. If a caliper fails, it can cause uneven wear on the brake pads and reduced braking ability. Signs Your Brakes Need Attention Knowing the signs of brake issues is crucial for ensuring your vehicle is safe to drive. At Musser Automotive, we recommend paying attention to these common symptoms: Squeaking or Squealing Noises: This often indicates that your brake pads are worn and need replacing. If you hear high-pitched sounds, it’s time for a brake inspection. Grinding Noises: If you hear grinding when applying the brakes, it typically means that the brake pads are completely worn down, and the metal of the caliper is grinding against the rotor. This can cause significant damage to your braking system and should be addressed immediately. Vibrations or Pulsing: If your steering wheel or brake pedal vibrates or pulses when you apply the brakes, it could indicate that your rotors are warped or unevenly worn. Soft or Spongy Brake Pedal: A soft brake pedal can mean there’s air in the brake lines or the brake fluid is low. In either case, you should get your brakes checked immediately to avoid complete brake failure. Pulling to One Side: If your car pulls to one side when braking, it may be due to an issue with your brake calipers, which could be sticking or failing to apply pressure evenly. Increased Stopping Distance: If you notice that your car is taking longer to stop than usual, it could mean that your brake pads are worn or your brake fluid is low. How to Maintain Your Brakes At Musser Automotive in Bowling Green, KY, we encourage our customers to follow these essential tips to ensure their brakes remain in peak condition: Check Brake Pads Regularly: Brake pads should be checked every 12,000 miles or so, depending on your driving habits. If your pads are worn down to 3mm or less, it's time for a replacement. Change Brake Fluid Periodically: Brake fluid absorbs moisture over time, which can cause corrosion in your brake lines and reduce the efficiency of your braking system. We recommend changing your brake fluid every 2 years or 24,000 miles. Inspect Brake Rotors: Rotors should be checked for signs of warping, cracks, or uneven wear. If your rotors are damaged, they may need to be resurfaced or replaced to restore proper brake function. Replace Worn Brake Pads: Never ignore the need to replace worn brake pads. Worn pads not only reduce braking performance but can also damage the rotors, leading to more costly repairs. Pay Attention to Brake Noises: Don’t ignore unusual brake noises. Squeaking, squealing, or grinding can all be early warning signs of brake issues. Why Choose Musser Automotive for Your Brake Maintenance?
