Manufacturer Identification -- 49 CFR Part 566

If a motor vehicle or item of replacement motor vehicle equipment contains a defect related to motor vehicle safety or fails to comply with an applicable Federal motor vehicle safety standard, the manufacturer is required under 49 U.S.C. § 30118 to furnish notification of the defect or noncompliance to the Secretary of Transportation, as well as to owners, purchasers, and dealers of the motor vehicle or replacement equipment, and to remedy the defect or noncompliance without charge to the owner. To ensure that manufacturers are meeting these and other responsibilities under the statutes and regulations administered by NHTSA, the agency issued 49 CFR Part 566, Manufacturer Identification. The regulations in Part 566 require manufacturers of motor vehicles or motor vehicle equipment, other than tires, to which a Federal motor vehicle safety standard (FMVSS) applies, to submit to NHTSA, on a one-time basis, identifying information on themselves and on the products that they manufacture to those standards. Manufacturers are required to submit identifying information to NHTSA no later than 30 days after they begin to manufacture motor vehicles or motor vehicle equipment subject to the FMVSS.
