1. (a) A manufacturer shall:

   1. (1) Review warranty claim records for each engine family or test group on a quarterly basis to determine and compile by cumulative total the number of claims made for emission-related components. The data compiled shall be based on all warranty claims, without any prescreening of data as to the validity of the claims. In the case of heavy-duty vehicles or engines, a manufacturer may use nationwide data for monitoring war-ranty claims of a California-certified engine family or test group which is also certified by the United States Environmental Protection Agency.
   2. (2) Categorize warranty claims for each engine family or test group by the specific emission control component replaced or repaired.
   3. (3) On the basis of data obtained subsequent to the effective date of these regulations, file an emission warranty information report for each quarter when the cumulative number of unscreened warranty claims for a specific emission-related component or repair represent at least one percent or twenty five (whichever is greater) of the vehicles or engines of a California-certified engine family or test group.

2. (b) The emission warranty information report shall contain the following information in substantially the format outlined below:

   1. (1) The manufacturer's corporate name.
   2. (2) A description of each class or category of California-certified vehicles or engines affected by a warranty replacement or warranty repair of a specific emission-related component, including model year and engine family or test group.
   3. (3) The number and percentage of vehicles or engines in each engine family or test group for which a warranty replacement or warranty repair of a specific emission-related component was identified.
   4. (4) A short description of the specific emission-related component that was replaced or repaired under warranty.
3. (c) Emission warranty information reports shall be submitted not more than 25 days after the close of a calendar quarter. Subsequent to the filing or an emission warranty information report, a manufacturer shall submit quarterly reports updating the number and percentage of emission-related warranty claims with the most recent information, unless a recall has been implemented. Emission warranty information reports and updates shall be submitted to the Chief, Emissions Certification and Compliance Division, 4001 Iowa Ave, Riverside, CA 92507.
4. (d) The records described in Section 2144(a)(1) of these procedures and the records used under the alternative procedure described in Section 2142(a) of these procedures shall be made available to the Executive Officer upon request.

For purposes of this section, any cross-referenced section in title 13 or title 17 of the California Code of Regulations shall refer to the section identified as the alternative version “(Alternative)” for the corresponding section, to the extent an alternative version of that section exists.
