Title 49 › SUBTITLE VI — MOTOR VEHICLE AND DRIVER PROGRAMS › PART C — INFORMATION, STANDARDS, AND REQUIREMENTS › CHAPTER 329 — AUTOMOBILE FUEL ECONOMY › § 32907
Manufacturers must tell the Secretary of Transportation if they will meet the fuel economy standard for a model year, what they have done or plan to do to meet it, and any other information the Secretary requires. They must send that report during the 30 days before each model year starts and again starting on the 180th day of the model year. If the manufacturer later decides those steps won’t be enough, it must report extra steps and say whether those will ensure compliance. The reporting rule does not apply if the maker is following an alternative fuel economy standard. Under rules set by the Secretary or the EPA Administrator, manufacturers must keep records, run tests, make reports, and give information or items when asked. A government officer who shows ID may inspect vehicles and records at a reasonable time and in a reasonable way. U.S. district courts can order a manufacturer to follow these requests and can punish failure as contempt of court.
