Background:

A key measure in CARB’s Revised Proposed 2016 State Strategy for the State Implementation Plan (State SIP Strategy) is ensuring that in-use heavy-duty vehicles continue to operate at their cleanest possible level (Lower In-Use Emission Performance Level).  Amendments to warranty provisions are an important part of that measure.  The State SIP Strategy is critical for attaining federal health-based air quality standards for ozone in 2023 and 2031 in the South Coast and San Joaquin Valley air basins, as well as fine particulate matter standards in the next decade.

As previously noticed, CARB is considering lengthening the required warranty period for HDVs to better reflect the real-world longevity of modern HDVs, and to promote lower NOx emissions during their service lives.  Class 8 HDVs frequently operate upwards of a million miles before major overhaul is needed, but they are required to be warranted for only 100,000 miles under existing CARB and U.S. EPA regulations.

Additionally, to ensure that maintenance provisions do not inadvertently shorten the proposed lengthened warranty periods, or otherwise transfer the liability of component replacement from manufacturer to vehicle owner during the lengthened warranty periods, CARB proposes to change the language in 13 CCR 2036 (d) that limits warranty to the first scheduled maintenance interval by aligning with existing federal provisions that do not allow scheduled maintenance to truncate warranty.  The minimum scheduled maintenance intervals specified in § 86.004 25 of the “California Test Procedures” will also be revised to reflect current industry practices for scheduled component replacements, minimizing vehicle owners paying to replace components that are still under warranty.  A proposal for longer HDV emission warranty periods and revised maintenance provisions is scheduled for Board consideration in May 2018.
