At what mileage do catalytic converters go bad?
Catalytic converters, an essential component of a vehicle's exhaust system, typically last between 10 to 15 years or 100,000 to 150,000 miles. However, various factors can cause them to fail prematurely. The exact mileage at which a catalytic converter goes bad can vary depending on driving conditions, maintenance, and the quality of the converter itself.
Factors Affecting Catalytic Converter Lifespan
Several factors can contribute to the premature failure of a catalytic converter:
- Mileage: As a general rule, catalytic converters start to deteriorate after around 100,000 miles of use.
- Age: Catalytic converters can last up to 15 years, but their performance may degrade over time due to exposure to high temperatures and exhaust gases.
- Driving Conditions: Frequent short trips, stop-and-go driving, and driving in heavy traffic can all put extra strain on the catalytic converter, leading to faster deterioration.
- Maintenance: Neglecting regular maintenance, such as oil changes and tune-ups, can contribute to catalytic converter failure.
- Fuel Quality: Using low-quality fuel or fuel with high sulfur content can also damage the catalytic converter over time.
It's important to note that the lifespan of a catalytic converter can vary significantly based on these factors, and regular inspections and maintenance are crucial to ensuring its longevity.
Signs of a Failing Catalytic Converter
Some common signs that a catalytic converter is failing include:
- Reduced fuel efficiency
- Difficulty starting the vehicle
- Increased engine noise or vibration
- Visible discoloration or damage to the converter
- Illumination of the "Check Engine" light
If you notice any of these symptoms, it's important to have your vehicle inspected by a qualified mechanic to determine the cause and address the issue before it leads to more serious problems.
Maintaining Your Catalytic Converter
To extend the life of your catalytic converter, it's important to follow these maintenance tips:
- Regularly change your engine oil and use high-quality fuel
- Avoid excessive idling or driving in stop-and-go traffic whenever possible
- Have your vehicle's emissions system checked and serviced regularly
- Address any engine performance issues, such as misfiring or poor fuel combustion, promptly
By following these best practices, you can help ensure that your catalytic converter lasts as long as possible, saving you the cost of a costly replacement.

Lifespan of a Catalytic Converter
If your vehicle is kept in good working order, it can function well for more than 100,000 miles and sometimes as long as the vehicle is running and driving.
How can I check if my catalytic converter is bad?
Diagnosing Catalytic Converter Issues
- step 1: obtain vehicle history.
- step 2: correct other engine codes.
- Step 3: Correct Exhaust System Leaks.
- Step 4: Check Converter Temperature.
- Step 5: check backpressure.
- step 6: check o2 (oxygen) sensor.
- step 7: examine cooling system.
- step 8: inspect fuel system.
What are the three most leading failures of a catalytic converter?
Most catalytic converter failures fall under one of three categories: Overheated, melted or broken converters.
How much does it cost to replace a catalytic converter?
$300.00 to $2,500.00
For direct-fit options, a replacement can cost anywhere from $300.00 to $2,500.00, depending on the model, for just the cost of the part. You should also think about labor costs, which could cost between $70 and $130 an hour to install the converter.
At what mileage should a catalytic converter be replaced?
A catalytic converter typically lasts about 70000 to 100000 miles, although this can vary based on several factors, including: Driving Conditions: Frequent short trips can lead to more wear and tear. Vehicle Maintenance: Regular maintenance, such as oil changes and tune-ups, can extend its life.
Is it worth fixing a catalytic converter?
Issues like reduced engine power, stalling, or poor acceleration can all be signs that there is an issue with your catalytic converter. Replacing it will restore your engine performance, but it may not always be worth the cost. That will depend on how poorly your engine is currently performing.
What happens if you keep driving with a bad catalytic converter?
Driving with Bad Catalytic Converter
If you encounter some of these issues when you're driving, you should get them replaced since they could be harmful to the engine. Those symptoms might lead to complete engine failure, which is a lot worse than any annoying noises or smells.
How do you know when a catalytic converter needs to be replaced?
Please be on the lookout for these signs, so you know when to take your car to the catalytic converter specialists at Northrich Automotive.
- RATTLING NOISE.
- BLUE EXHAUST.
- POOR ENGINE PERFORMANCE.
- POOR FUEL MILEAGE.
- "CHECK ENGINE" LIGHT ILLUMINATES.
- SULFUR SMELL FROM EXHAUST.
- FAILED EMISSIONS TEST.
How does a car act when the catalytic converter is bad?
Driving with Bad Catalytic Converter
If you're noticing sluggish engine performance, reduced acceleration, a smell of rotten eggs or sulfur from the exhaust, dark exhaust smoke, or extreme heat coming from under the vehicle, these are symptoms of a clogged Catalytic Converter, and it should be repaired soon.
What is the average lifespan of a catalytic converter?
10 years
Catalytic Converters should run for at least 10 years, but they don't have to get swapped out as soon as those 10 years are up. It only needs to get replaced whenever you begin to see those problems occur and if it's recommended by the service technicians.
