There are differences from one vehicle year, make and model, gasoline and diesel engines. There are also differences between trucks that are over/under 8,500 pounds gross vehicle weight (GVW).
Contact The Dealer: If your 8 year old or newer vehicle fails a smog check or its check engine light (service engine soon light) turns on or flashes, we recommend contacting your local dealership to see if the repairs are covered under any emissions warranty, whether that be Federal or California. If you run in to a service writer unfamiliar with Federal Emission Warranty or California Emissions Warranty, ask to speak with their supervisor.
What Reasons Can a Manufacturer Use to Deny a Warranty Claim?
If your vehicle is within the age and mileage requirements for the applicable emissions warranty, the manufacturer can only deny coverage if evidence shows that you have failed to properly maintain and use your vehicle, causing the part or emission test failure.
Some examples of misuse and lack of maintenance include:
- vehicle abuse (off-road or overloading); or
- tampering with emission systems, including removal or intentional damage of emission parts or emission systems; or
- improper maintenance, including failure to follow maintenance schedules and instructions specified by manufacturer, or use of replacement parts which are not equivalent to the originally installed parts.
