How much does it cost to replace a catalytic converter on a Toyota Sequoia?

Replacing a catalytic converter on a Toyota Sequoia typically costs about $1,000 to $2,500 for a single converter, with higher totals if your model has two converters or if OEM parts are used. The exact price depends on the year, the part quality (OEM vs aftermarket), and the labor rate at your shop.

What drives the price

Prices vary based on several factors. The main cost drivers are the type of parts you choose, how many catalytic converters need replacement, and the labor time required. Regional labor rates and shop policies can also push the total higher or lower.

• Parts cost: OEM (Toyota) replacements tend to be more expensive than aftermarket equivalents. The Sequoia's exhaust setup can involve one or two catalytic converters depending on the model year, which directly affects the total parts bill.


• Number of converters: Many Sequoia models use one catalytic converter per exhaust bank, but some configurations may require two. Replacing two units doubles most of the parts and increases labor time.


• Labor time and rate: Labor typically runs 1–3 hours per converter, and shop rates vary by region. Labor costs can swing significantly between independent shops and dealerships.


• Additional hardware and sensors: Gaskets, mounting bolts, and O2 sensor(s) may need replacement, adding to the overall cost.


• Vehicle condition: Rusted or hard-to-reach exhaust components can extend labor time and raise the price.

In short, the total you pay is a combination of the parts choice, how many units are involved, and how long the shop spends on the job.

Typical price ranges by scenario

Below are common scenarios to help you gauge the range, with approximate totals that reflect typical parts and labor in many U.S. markets. Actual prices will vary by region and shop.

• Single catalytic converter replacement (OEM parts): Parts about $900–$1,700; labor roughly $250–$700; total typically $1,150–$2,400.


• Single catalytic converter replacement (aftermarket parts): Parts about $150–$900; labor roughly $250–$700; total typically $400–$1,600.


• Two catalytic converters (OEM parts): Parts about $1,800–$3,400; labor roughly $500–$1,100; total typically $2,300–$4,500.


• Two catalytic converters (aftermarket parts): Parts about $500–$1,800; labor roughly $500–$1,100; total typically $1,000–$2,900.

These figures illustrate why OEM replacements usually cost more, and why replacing two units can significantly raise the total versus a single converter swap.

Ways to save money and avoid common pitfalls

homeowners and fleet managers alike can pursue smarter buying choices without sacrificing reliability. Consider these strategies when planning a catalytic converter replacement.

• Get a precise diagnosis: Ensure the issue is actually a failed catalytic converter and not a failing O2 sensor, exhaust leak, or sensor wiring that mimics a catalytic problem.


• Shop around: Obtain quotes from both dealerships and independent auto shops to compare parts and labor costs.


• Consider aftermarket with standards: Aftermarket converters that meet EPA/CARB standards can offer substantial savings while remaining compliant.


• Check warranty coverage: Federal emissions warranty often covers catalytic converters for 8 years/80,000 miles; verify whether your Sequoia is still within the coverage window and what’s included in your state’s emissions warranty.


• Factor in installation specifics: If the exhaust is corroded or fasteners are seized, ask about potential extra charges for labor or parts.

Sticking with a reputable shop, ensuring proper installation, and confirming part compliance with local emission regulations can help you avoid unexpected costs.

What to do next

If you suspect a catalytic converter issue, schedule a diagnostic with a qualified technician to confirm the failure mode and obtain a detailed, written quote. Ask for a breakdown that separates parts, labor, and any miscellaneous fees, and request multiple quotes to compare both OEM and aftermarket options. This approach helps you balance reliability, compliance, and total cost over the life of your Sequoia.

Summary

For a Toyota Sequoia, replacing a catalytic converter generally runs from about $1,000 to $2,500 for a single unit, with higher totals if your vehicle uses two converters or if OEM parts are specified. Expect roughly $2,300–$4,500 for two converters with OEM parts, or $1,000–$2,900 with aftermarket parts. Costs vary by model year, parts choice, labor rates, and local regulations, so obtaining multiple quotes is the best way to ensure fair pricing.

Is it worth fixing a catalytic converter?

Yes, it is worth replacing a catalytic converter because it is essential for your car's performance, longevity, and legality. Driving without one can lead to poor acceleration, reduced engine performance, lower fuel efficiency, and environmental damage. Additionally, you will likely not be able to pass an emissions test, which is required to legally register and drive your car in most places.

Reasons to replace a catalytic converter

• Legality: You cannot pass an emissions test without a properly functioning catalytic converter, and many states require one for registration. 
• Vehicle performance: A failed or clogged converter can cause a significant loss of engine power, leading to poor acceleration and slower top speeds. 
• Engine and exhaust damage: Driving with a bad converter can cause damage to other parts of the engine and exhaust system, such as overheating or causing more significant engine stress. 
• Environmental impact: The converter's primary function is to convert toxic pollutants into safer gases, so a replacement is necessary to prevent releasing harmful fumes into the environment. 
• Fuel efficiency: A failing converter can negatively impact your gas mileage, leading to higher fuel bills. 
• Resale value: A car without a catalytic converter will have a lower resale value and may be difficult to sell.

What to consider before replacing

• Diagnosis: Have a mechanic properly diagnose the issue. Some symptoms can be caused by other problems, like a bad oxygen sensor or ignition issues. 
• Underlying issues: Investigate why the converter failed in the first place. Issues like burning oil, engine misfires, or coolant leaks can cause a new converter to fail prematurely. 
• Cost: Be prepared for a high cost, as catalytic converters are expensive due to the precious metals they contain. This can be a significant expense, but the negative consequences of not replacing it are more costly in the long run.

What year of Toyota Sequoia to stay away from?

You should be wary of Toyota Sequoia model years 2001-2008, as they experienced a higher number of issues, particularly concerning rust, brake problems, and various electronic failures in early years like 2001 and 2002. The 2008 model also introduced the second generation with early transmission concerns, notes MotorBiscuit. Additionally, some models from 2004-2010 are prone to frame rust.
 
Models to be cautious about

• 2001-2004: These years had engine, brake, and rust issues. 
• 2002: This model is particularly flagged for problems with the Vehicle Stability Control (VSC), oxygen sensors, and premature brake wear. 
• 2008: As the first year of the second generation, it can have early transmission problems. 
• 2004-2010: These models have a higher risk of frame and suspension rust. 

Other considerations

• Recalls: Check for open recalls on any model year you are considering, as some years have had multiple recalls (e.g., 2020 and 2021). 
• Maintenance: Even with a model year known for issues, a thoroughly maintained vehicle with a solid history can still be a good purchase, so check maintenance records.
