B. DESIGN AND DEFECT WARRANTY
The Design and Defect Warranty covers repair of emission related parts which become defective during the warranty period. The Design and Defect warranty for model year 1995 and newer light-duty cars and trucks is outlined below:
Design and Defect Warranty Coverage for 1995 and newer light-duty vehicles:
* Emission control and emission related parts are covered for the first 2 years or 24,000 miles of vehicle use; and
* Specified major emission control components are covered for the first 8 years or 80,000 miles of vehicle use.
According to federal law, an emission control or emission related part, or a specified major emission control component, that fails because of a defect in materials or workmanship, must be repaired or replaced by the vehicle manufacturer free of charge as long as the vehicle has not exceeded the warranty time or mileage limitations for the failed part.
Design and Defect Warranty coverage may vary depending on the type of vehicle you have (e.g., heavy-duty trucks, motorcycles or recreational vehicles have different time and mileage requirements). To determine the length of warranty coverage that applies to your vehicle, look for the emissions warranty information in your owner's manual or warranty booklet. If you own a California vehicle, you may be entitled to additional warranty coverage.
The owner's manual or warranty booklet will also provide you with guidance on the procedures for obtaining warranty coverage. If you have questions about the emissions warranties on your vehicle or need help in filing a warranty claim, contact your local car dealer or the manufacturer's zone or regional representative listed in your owner's manual or warranty booklet.
What Emission Control and Emission Related Parts Are Covered by The Design and Defect Warranty?
An emission control part is any part installed with the primary purpose of controlling emissions. An emission related part is any part that has an effect on emissions. Listed below are some examples of parts or systems which fall under these definitions. A more complete list can be found in your owner's manual/warranty booklet. If any of the parts listed below fail to function or function improperly because of a defect in materials or workmanship, causing your vehicle to exceed federal emission standards, they should be repaired or replaced under the emissions warranty if your vehicle is less than 2 years old and has been driven less than 24,000 miles. One manufacturer may use more parts than another, so the following list is not complete for all vehicles.
EMISSION CONTROL PARTS
1. Exhaust Gas Conversion Systems: oxygen sensor, thermal reactor, catalytic converter, dual-walled exhaust pipe
2. Exhaust Gas Recirculation System: EGR valve, thermal vacuum switch, EGR solenoid, EGR spacer plate, EGR backpressure transducer, sensor and switches used to control EGR flow
3. Evaporative Emission Control System: purge valve, fuel filler cap, purge solenoid, vapor storage canister, and filter
4. Positive Crankcase Ventilation (PCV) System: PCV valve, PCV solenoid
5. Air Injection System: Air pump diverter, bypass, or gulp valve, reed valve, anti-backfire or deceleration valve
6. Early Fuel Evaporative (EFE) System: EFE valve, thermal vacuum switch, heat riser valve
7. Fuel Metering System: electronic control module (unit) or EFI air flow meter, computer command module or mixture control unit, deceleration controls, electronic choke, fuel injectors, fuel injection units and fuel altitude compensator sensor, bars or rails for EFI or TBI systems, mixture settings on sealed fuel mixture control solenoid, diaphragm or other systems, fuel metering components that achieve closed/other feedback control sensors/loop operation switches and valves
8. Air Induction System: thermostatically controlled air cleaner, air box
9. Ignition Systems: electronic spark advance timing advance/retard systems, high energy electronic ignition
10. Miscellaneous Parts: hoses, gaskets, brackets, clamps, and other accessories used in the above systems
EMISSION RELATED PARTS
These are examples of other parts of your vehicle which have a primary purpose other than emissions control but which nevertheless have significant effects on your vehicle's emissions. If any of these parts fail to function or function improperly, your vehicle's emissions may exceed federal standards. Therefore, when any of the parts of the following systems are defective in materials or workmanship and have failed in a way that would be likely to cause your vehicle's emissions to exceed federal standards, they should be repaired or replaced under the emissions warranty:
1. Fuel Injection System: fuel distributor
2. Air Induction System: turbocharger, intake manifold
3. Exhaust System: exhaust manifold
4. Ignition System: distributor, spark plugs, ignition wires and coil
5. Miscellaneous Parts: hoses, gaskets, brackets, clamps, and other accessories used in the above systems.
What Are Specified Major Emission Control Components?
There are three specified major emission control components, covered for the first 8 years or 80,000 miles of vehicle use on 1995 and newer vehicles:
* Catalytic converters.
* The electronic emissions control unit or computer (ECU).
* The onboard emissions diagnostic device or computer (OBD).
