Who is responsible for the costs of emissions repairs after a failure?

The vehicle owner is responsible for the costs of emissions repairs after a failure because they own the vehicle and are ultimately accountable for its maintenance and compliance with state emissions regulations. Vehicle owners must ensure their vehicles operate within the required emissions standards; therefore, any necessary repairs to address emissions failures fall under their responsibility.

Mechanics may conduct the repairs, but they are hired to provide a service rather than assume financial liability for the costs associated with emissions repairs. Similarly, state government entities and emissions testing agencies provide oversight and enforcement of emissions standards but do not cover the costs of repairs for individual vehicles. The obligation to maintain and repair a vehicle, ensuring it meets emissions regulations, lies with the owner who operates the vehicle.
