Does a Chevy Traverse have a catalytic converter?
Yes. The Chevrolet Traverse is equipped with catalytic converters as part of its exhaust system to meet emissions regulations; the exact number and placement can vary by model year and engine configuration.
In modern gasoline-powered SUVs like the Traverse, the catalytic converter is a critical component that reduces pollutants by converting them into less harmful compounds. This article explains how the Traverse uses catalytic converters, where they are typically located, and what variations exist by year and engine.
What a catalytic converter does
A catalytic converter is part of the exhaust system that uses chemical reactions to reduce harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides before the exhaust leaves the vehicle. It helps a car meet emissions standards and improve air quality.
Does the Traverse have a catalytic converter?
Most Chevy Traverse models rely on catalytic converters as part of the exhaust system. The specific arrangement can differ based on the year, engine, and emissions package. In practice, many V6 Traverse configurations include more than one converter in series along the exhaust path.
Engine and year variations
Across generations, the Traverse has used different engine options, and the exhaust layout has evolved. In the modern lineup (especially with the 3.6L V6 introduced around 2009 and continued in the 2020s), it is common to have two catalytic converters in the exhaust system: a catalytic converter close to the engine (pre-cat) and a second catalytic converter further back. Some configurations may place both converters in a single assembly or in separate sections, but the goal remains the same: reduce emissions before exhaust exits the vehicle.
Regardless of the exact arrangement, the presence of catalytic converters is standard across gasoline Traverse models to comply with EPA/CARB requirements.
Below is a snapshot of typical configurations you may encounter in the Traverse lineup by era and engine:
- Modern 3.6L V6 (many 2013–present models): usually two catalytic converters in series along the exhaust path—one near the manifold and a second farther back.
- Earlier generations with smaller engines or different emissions packages: may have a single catalytic converter, but still part of the exhaust system for emissions compliance.
- Some trims or market-specific variants may consolidate or relocate catalytic components, but none of the major gasoline Traverse configurations lack a catalytic converter.
Note: Exact layout depends on year, market, and engine option. Always consult the owner's manual or a service diagram for your VIN.
Signs a catalytic converter may need attention
When monitoring the health of the exhaust system, be aware of common indicators that a converter may need service:
- Decreased engine performance or acceleration and reduced fuel efficiency
- Rattling noises from under the vehicle, especially when starting or idling
- Illumination of the check engine light and stored trouble codes indicating catalyst efficiency below threshold
- Sulfur-like or rotten egg smell from exhaust
- Failed passing of emissions tests
If any of these symptoms appear, have the exhaust and catalytic converters inspected by a certified mechanic. Replacement costs vary by vehicle and region.
Summary
Yes, the Chevy Traverse uses catalytic converters as part of its exhaust system to meet emissions rules. The precise number and arrangement vary by year and engine, with most modern V6 versions commonly employing two converters in series. If you’re troubleshooting or planning maintenance, verify the exact configuration for your specific vehicle using the VIN and service documents.
How many catalytic converters are on a Chevy Traverse?
A Chevy Traverse typically has three catalytic converters, though some models may have a different number depending on the year and engine configuration. Most commonly, the setup includes one primary converter and two secondary ones.
- Typical configuration: Many models, including those from 2008-2017, feature three converters. This usually consists of a primary one and two secondary converters located on different banks of the exhaust system.
- Variations: Some models might have a different configuration, such as two or three, with one being a pre-catalytic converter closer to the exhaust manifold and one or two downstream converters.
- Diagnosis: If you are experiencing issues, such as a “check engine” light, it's best to have the vehicle diagnosed to confirm the number of converters and identify any problems.
How much is a catalytic converter for a Chevy Traverse?
between $3,405 and $3,515
The average cost for a Chevrolet Traverse Catalytic Converter Replacement is between $3,405 and $3,515. Labor costs are estimated between $181 and $266 while parts are priced between $3,224 and $3,249.
Where is the catalytic converter located on a Chevy?
The catalytic converter is a part of your car's exhaust system that helps to reduce harmful emissions by converting toxic gases into less harmful substances. It is located underneath your vehicle, between the engine and the muffler.
What's the most common problem with a Chevy Traverse?
The most common problems with the Chevy Traverse include transmission issues, engine troubles like excessive oil consumption and timing chain problems, and steering and electrical system malfunctions. These issues are more prevalent in earlier models, with transmission and engine problems being a frequent complaint across various model years.
Common problems by system
This video explains the common reliability issues and problems with the Chevy Traverse: 59sNexologyYouTube · Oct 28, 2025
- Transmission: Owners report a range of problems, including rough shifting, slipping gears, and complete transmission failure. Some models have issues with a "Shift to Park" message, especially after shutting down the vehicle.
- Engine:
- Excessive oil consumption: Some owners have reported that their engines consume a lot of oil.
- Timing chains: Earlier models are prone to timing chain issues, which can lead to a ticking noise and potential failure.
- Other issues: Some models experience engine stalling, shuddering, and a check engine light.
- Steering: Problems include power steering fluid leaks, noisy steering, and a general lack of power steering feel.
- Electrical: Issues can include a malfunctioning infotainment system, battery drain, and various error messages. In some cases, components like alternators and starter motors have failed prematurely.
- Other:
- Brakes: Unusual brake noises have been reported.
- Climate control: Air conditioning system problems, such as compressor failure and refrigerant leaks, are also common.
- Exhaust: Exhaust leaks and other issues with the exhaust system have been noted.
