California Emissions Control Warranty
For California certified vehicles, manufacturers must warrant that the vehicle will pass any Smog Check inspection during the first 3 years or 50,000 miles.
This means that any
component failure leading to a Smog Check inspection failures during the first 3 years or
50,000 miles must be repaired under warranty free of charge, unless there is abuse, neglect,
or tampering (as defined in the warranty) that affects the failure.
For “high-priced” emission control parts, the emission control warranty extends to 7 years or 70,000 miles. High priced parts are determined at the time of vehicle certification and listed in the warranty statement included in the owner’s information package provided by the vehicle manufacturer.
For Partial Zero Emission Vehicles (PZEV) the warranty extends to 15 years or 150,000 miles for all emission related components, and 10 years for hybrid vehicle batteries.
Specific vehicle warranties vary and are determined at the time of vehicle certification. Always refer to the warranty for each vehicle to determine applicable coverage.
of Smog Check failures not covered by the emission warranties are the responsibility of the
motorist and would be subject to the Smog Check repair cost waiver requirements.
The federal emissions warranty applies to 1995 and newer light duty vehicles. The warranty covers the cost of repairs that are needed to correct a Smog Check failure for the first 2 years or 24,000 miles. Some major emissions components (catalytic converters, electronic control unit/computer) are covered for the first 8 years or 80,000 miles. Heavy-duty vehicle warranty terms may be different. Note: Always refer to the warranty for each vehicle to determine applicable coverage.
