In this guide, we look closer at the legal protection for catalytic converter defects. We explain the coverage under the powertrain warranty and show you the legal recourse for warranty claims.
While the GM Powertrain Limited Warranty provides broad coverage for major engine and drivetrain components, it does not extend to the catalytic converter. Instead, catalytic converters are generally protected under the Federal Emissions Warranty, which covers defects in materials or workmanship for 8 years or 80,000 miles, whichever comes first.
The GM Powertrain Limited Warranty protects key components of your vehicle’s engine, transmission, and drivetrain. Common covered components include the engine block, cylinder heads, timing chains, internal transmission parts, and drive axles. It typically excludes wear-and-tear components and damage from neglect or accidents.
Now that you know what is covered under the GM powertrain warranty, it's important to understand its duration. GM’s coverage lasts 5 years or 60,000 miles, whichever comes first. However, the limited warranty does not cover emissions components, including the catalytic converter. If you need help understanding the GM powertrain warranty coverage details, it’s best to speak with one of our lemon law attorneys.
Catalytic converters are not covered under the GM Powertrain Limited Warranty. Instead, they fall under the Federal Emissions Warranty, which lasts for 8 years or 80,000 miles, whichever comes first.
The coverage only includes defects in materials or workmanship. Any failures due to an accident, misuse, corrosion, or modifications are excluded. If you need a GM warranty catalytic converter replacement, the dealer would still be responsible for the labor and repair.
When the vehicle requires warranty repairs, you must file a claim through GM. We outline the step-by-step process below, so you have fewer warranty coverage disputes to deal with. Remember to keep all service records and communication to file a successful claim.
If you need to file a GM warranty claim for the catalytic converter, there's a certain process you should follow to make sure it goes smoothly. Here's how our attorneys usually handle it when they're working with clients.
Following these steps ensures your GM warranty claims are properly documented and increases the likelihood of a successful catalytic converter replacement.
Even when the catalytic converter is covered under the Federal Emissions Warranty, owners may face obstacles when filing a claim. Common denial reasons include the following:
It’s important to understand that the Magnuson-Moss Warranty Act prohibits denial due to aftermarket modifications unless they specifically caused the failure. However, many dealerships try to skirt around this and blame the consumer for problems caused by poor workmanship and materials.
One of the most common challenges with warranty claims is a lack of documentation. If you are missing any service history or repair records, you could jeopardize the claim.
Before trying to handle a GM warranty catalytic converter replacement on your own, consider hiring an attorney. While you can file a claim without a lawyer, it’s best to have a professional on your side.
It's important to understand the differences between GM’s powertrain and bumper-to-bumper warranties. This will help you figure out which warranty covers what. Let's dive into how each warranty deals with components like catalytic converters and other important parts. This overview sets the stage for exploring how each warranty handles components like catalytic converters and other key parts.
There are major differences between the GM powertrain vs. bumper-to-bumper warranty. First, let’s look at covered components. The powertrain limited warranty covers major components, such as the engine, transmission, and drivetrain. It also covers supporting components, such as the engine control module and transmission control module. The bumper-to-bumper warranty offers broader protection. It covers most other vehicle components.
Another difference is the vehicle’s warranty term. GM and Chevrolet vehicles are covered by the bumper-to-bumper warranty for 3 years or 36,000 miles. In comparison, the powertrain warranty lasts 5 years or 60,000 miles, offering longer protection.
Warranty coverage differences extend to the other protections as well. With a new GM vehicle, consumers also get the federal emissions control systems warranty, a corrosion (rust through protection) warranty, and complimentary roadside assistance.
Catalytic converters are not covered under the powertrain limited warranty, but receive protection through the federal emissions warranty. Coverage is limited to defects in materials or workmanship. Therefore, you can’t file a claim for misuse, corrosion, or damage caused by modifications.
Trying to figure out your Chevy warranty coverage can be a daunting task. You can read the warranty manual to learn more about the coverage. Here are a few tips.
To verify if a catalytic converter defect is covered, here are some important steps to follow.
Emissions system issues are among the most common car problems to occur. Here are a few of the most notable catalytic converter failure symptoms to be aware of.

After purchasing your vehicle, it's important to understand the warranty limitations, especially when it comes to expensive components like the catalytic converter. Here are some of the most asked questions regarding the applicable new vehicle warranty and how it applies to the catalytic converter.
No, catalytic converters are not covered under the GM Powertrain Warranty. They fall under the Federal Emissions Warranty, which excludes damage from corrosion and is separate from protections like the bumper-to-bumper limited warranty that covers the entire vehicle.
Catalytic converters are covered under GM’s Federal Emissions Warranty, which typically lasts 8 years or 80,000 miles from vehicle delivery. This coverage is separate from the bumper to bumper warranty, and exact coverage periods typically appear in the owner’s manual for each vehicle.
To file a claim, take your vehicle to an authorized GM dealer and explain the issue with the emissions component. While typical powertrain warranties don’t cover catalytic converters, the Chevrolet warranty for emissions components usually does, provided you have service records and documentation showing the defect.
No, GM’s rust-through protection applies only to sheet metal components and does not cover catalytic converters. The corrosion protection warranty addresses issues like an actual hole in body panels, helping avoid unexpected repair costs, but it does not extend to select emissions related components.
No, the bumper to bumper coverage does not include catalytic converters, which are part of the emissions system. It mainly covers general vehicle components and internal electrical components, so owners should not rely on it for this warranty concern.
