The catalytic converter is an important component of your vehicle’s exhaust system, responsible for reducing harmful emissions and enabling proper engine performance. When it begins to fail, your vehicle’s efficiency and environmental impact are at risk. Recognizing the warning signs of a catalytic converter problem can help you address the issue before it leads to more severe trouble. At Ken’s Muffler & Brakes, we provide expert catalytic converter replacement in the greater Dallas area. Here’s a look at four symptoms of a catalytic converter problem.


Reduced Engine Performance

One of the first signs of a failing catalytic converter is a noticeable drop in engine performance. You may experience sluggish acceleration, reduced power, or difficulty climbing hills. This occurs because a clogged catalytic converter restricts exhaust flow, making it harder for your engine to function efficiently.


Decreased Fuel-Efficiency

A faulty catalytic converter can cause your vehicle to burn more fuel than usual. This happens because the engine has to work harder to push exhaust gases through the clogged or damaged converter. If you notice a significant drop in gas mileage, it’s worth having your catalytic converter inspected as part of the diagnosis.


Check Engine Light Illumination

The check engine light is often triggered when there’s an issue with the catalytic converter. Modern vehicles are equipped with oxygen sensors that monitor the efficiency of the converter. If the sensors detect abnormal readings, they will activate the check engine light. A diagnostic scan can confirm whether the catalytic converter is the source of the problem.


Rotten Egg Smell from the Exhaust

A common indicator of a catalytic converter problem is a strong sulfur or “rotten egg” smell coming from the exhaust. This odor is caused when the converter is no longer able to effectively neutralize hydrogen sulfide. If you detect this smell, it’s a sign that your catalytic converter may be failing and needs immediate attention.

4 Important Reasons to Always Stay Current with Oil Changes

by Ken’s Muffler & Brakes • 9 April 2025
Keeping up with regular oil changes is one of the simplest yet most important things you can do to protect your vehicle’s engine. While it’s easy to put off this maintenance task, sticking to your oil change schedule can save you money and hassle in the long run. At Ken’s Muffler & Brakes, we provide full-service oil changes in the greater Dallas area. Here are four reasons why you should always follow your recommended oil change intervals. Keeps Your Engine Properly Lubricated Motor oil plays a critical role in keeping all the moving parts of your engine properly lubricated. Without sufficient lubrication, metal components will grind against each other, causing excessive friction and wear. Over time, this can lead to serious engine damage, which may require costly repairs. Fresh oil helps ensure smooth engine operation and prevents premature wear and tear. Helps Prevent Engine Overheating Oil doesn’t just lubricate your engine—it also helps regulate its temperature. As it circulates, oil absorbs heat and carries it away from critical components. However, over time, old oil loses its ability to cool the engine effectively. Dirty or degraded oil can lead to overheating, which increases the risk of engine failure. Regular oil changes help keep your engine running at the optimal temperature. Improves Fuel-Efficiency Old, dirty oil forces your engine to work harder, which can reduce fuel-efficiency. A well-lubricated engine operates more smoothly, requiring less fuel to function properly. If you want to get the most miles per gallon out of your vehicle, sticking to your oil change schedule is a simple way to improve fuel economy and save money at the pump. Extends the Life of Your Engine Your engine is the heart of your vehicle, and taking care of it can significantly extend the life of your car. Regular oil changes reduce the risk of major engine problems by preventing excessive wear and keeping internal components in good condition. By following your manufacturer’s recommended oil change schedule, you help ensure that your engine lasts for many miles to come.

5 Warning Signs of Alternator Failure

by Ken’s Muffler & Brakes • 11 March 2025
Your vehicle’s alternator is responsible for keeping the battery charged and powering essential electrical components while the engine is running. When the alternator begins to fail, it can cause a range of problems. At Ken’s Muffler & Brakes, we provide expert alternator replacement and auto electric repair in the greater Dallas area. Here are five common signs that your alternator may be failing and in need of replacement. Battery Warning Light on the Dashboard Modern vehicles commonly have a battery warning light that illuminates when there’s an issue with the charging system. While this light is often mistaken for a simple battery problem, it can also indicate that the alternator is not generating enough power. If you see this warning, it’s best to have your charging system checked before your vehicle loses power completely. Dimming/Flickering Lights A frequent sign of alternator trouble is dim or flickering headlights, dashboard lights, or interior lights. Since the alternator supplies power to the vehicle’s electrical system, a weakening alternator may struggle to maintain consistent voltage. If multiple lights in your vehicle are acting erratically, it’s a strong indication that the alternator isn’t providing a steady electrical supply. Electrical Accessories Malfunctioning A failing alternator can lead to erratic behavior in your car’s electrical accessories. Power windows may operate slower than usual, the radio may cut in and out, or the air conditioning may not blow as strongly as before. If you experience multiple electrical issues at the same time, the alternator may be struggling to provide enough power to all systems. Dead Battery or Difficulty Starting If your car’s battery dies, it could be due to a failing alternator rather than the battery itself. When the alternator stops charging properly, the battery is forced to supply all of the power, which drains it quickly. Jump-starting the battery may temporarily resolve the issue, but if the alternator isn’t charging the battery, the problem will return. Testing both the battery and alternator can help determine the root cause. Strange Noises Coming from the Engine Unusual noises, such as grinding or whining, can indicate that the alternator’s internal components are wearing out. Ignoring these sounds can lead to complete alternator failure, leaving you stranded with a non-starting vehicle.
